It was still only a little after 7 o’clock, the Sun was pale, and the air was cool. The morning smelled delicious. After a difficult walk, Sam finally sat down by the pool, put away his compass (指南针) and lifted his field glasses. There they are! The mother swan was only a few feet away. She was sitting very close, not moving. The father swan was nearby. Both birds were listening and waiting. Both birds saw Sam, but they thought it didn’t matter. Sam stayed with these two great birds in the wild, just like old friends. That made him really happy.
In the morning, when the Sun was up in the sky, Sam focused his glasses on the nest (巢) again. At last, he saw a small head pushing through the mother’s feathers, the head of a baby swan. The baby climbed out of the nest. It had a grey head and neck, with soft fine feathers. Soon another baby appeared. Then another. Then the first one walked his way down into his mother’s feathers again for warmth. Then one tried to climb up his mother’s back, but her feathers were wet, and he fell off. The mother swan just sat and sat, enjoying her babies, watching them use their legs. One of the baby swans, more brave than the others, left the nest and walked around on the shore (岸边) of the island. When this happened, the mother swan stood up. It was time for her to lead her children to the water. The baby swans did as their mother did and soon found it easy to swim.
“One, two, three, four, five,” Sam counted. “One, two, three, four, five. Five babies, just as sure as I am alive! This is my lucky day.” The father swan, when he saw his children in the water, felt like he should act like a father. He began by making a speech.

The ocean is a huge and amazing world. It covers more than two-thirds of the Earth’s surface. The ocean is home to millions of living things, from tiny plankton to huge whales.
The ocean is very important to us. It provides us with many things. For example, we get fish, shrimp and other seafood from the ocean. Seafood is an important part of many people’s diet. The ocean also gives us salt, which we use to cook food.
Moreover, the ocean helps regulate (调节) the Earth’s climate. It absorbs (吸收) a lot of heat from the sun. This helps keep the Earth’s temperature stable. The ocean also produces a large amount of oxygen. About half of the oxygen we breathe comes from the ocean.
However, the ocean is facing many problems. Pollution is a big threat. People throw plastic bags, bottles and other rubbish into the ocean. This hurts marine animals. Many animals mistake plastic for food and eat it, which causes them to die. Overfishing is another problem. Some fishermen catch too many fish, which reduces the number of fish in the ocean.
We must protect the ocean. We can reduce plastic use by using reusable bags and bottles. We can also support sustainable fishing (可持续捕鱼). Governments should make stricter rules to stop ocean pollution. Everyone has a responsibility to protect the ocean. Let’s work together to keep the ocean clean and healthy.
1．How much of the Earth’s surface does the ocean cover
A．Less than one-third. B．More than two-thirds. C．About half. D．All of it.
2．What do we get from the ocean
① Seafood ② Salt ③ Oxygen ④ Plastic
A．①②③ B．①②④ C．①③④ D．②③④
3．Why is the ocean important to the Earth’s climate
A．It produces oxygen. B．It provides seafood.
C．It absorbs heat from the sun. D．It gives us salt.
4．What problems is the ocean facing
A．Pollution and overfishing. B．Pollution and cold weather.
C．Overfishing and lack of oxygen. D．Lack of salt and pollution.
5．What can we do to protect the ocean
A．Throw more plastic into the ocean. B．Ignore the ocean problems.
C．Catch as many fish as possible. D．Use reusable bags and bottles.

When we look at the Earth, we see many different things. Sometimes, you may hear people talk about landform and landscape. Are they the same thing Let’s find out!
A landform is a natural feature of the Earth’s surface. Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms. They are made by nature over a long, long time. For example, mountains are formed when huge pieces of the Earth’s surface push against (撞) each other. Valleys can be made by rivers cutting through the land little by little. Each landform has a name that tells us what it looks like and how it was formed. Scientists study landforms to learn about the history of the Earth.
A landscape, on the other hand, is what you see when you look at an area of land. It includes (包括) landforms, but it also has other things like plants, buildings, and lakes. Imagine standing on top of a hill. You can see green trees waving in the wind, a small village with houses, and a clear lake nearby. All these things together make up the landscape. A landscape can change rapidly. If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months.
Let’s take a forest in the mountains as an example. The mountain is the landform — it’s a natural feature of the Earth. But when you see the tall trees, hear the birds singing, and watch a little stream (溪流) running down the mountain, that’s the landscape.
So, the key difference is this: landform is about the natural shapes of the Earth, and landscape is about the whole view of an area, including both natural and man-made things. Next time you go on a trip, try to enjoy different landforms and describe (描述) the beautiful landscapes around you!
1．Which of the following is a landform
A．A newly-built bridge. B．A flat plain.
C．A group of trees. D．A small house.
2．What can we learn from the text about how mountains are formed
A．They are made by people building up the land.
B．They are formed when rivers cut through the land.
C．They are formed when the Earth’s plates push into each other.
D．They are formed by heavy rain and strong winds.
3．What does the underlined word “rapidly” in Paragraph 3 probably mean
A．Brightly. B．Quickly. C．Powerfully. D．Quietly.
4．What does “landscape” usually include
A．Only landforms. B．Only natural things.
C．Just man-made things. D．Landforms, trees, houses and lakes.
5．How does the writer explain the difference between landform and landscape
A．By telling stories. B．By listing numbers.
C．By giving examples. D．By asking questions.

Lucy is a 16-year-old environmental volunteer who devotes herself to urban biodiversity protection. Last year, she signed up for the City Green Initiative, a local non-profit organization dedicated to building small ecological gardens and green corridors in crowded residential areas. Every Saturday morning, she meets her teammates at the community square, then they walk to the nearby abandoned lot to work. They clear the garbage, turn the soil, and plant native flowers and shrubs that are attractive to bees and butterflies. They also set up wooden bird feeders and water basins in the trees, hoping to draw more small birds to settle down. Besides these tasks, Lucy and her team regularly visit the neighborhood families to give out brochures. They teach residents how to sort household waste properly and how to recycle materials like plastic bottles and old newspapers into useful crafts.
Lucy’s interest in this meaningful cause started with a school lecture on sustainable living. The speaker shared how a tiny urban garden could provide shelter for dozens of species and improve the air quality around the community. Deeply moved, Lucy realized that even small daily actions could make a big difference to the environment. In her spare time, she also gives 15-minute talks at the community center, sharing practical tips on creating a wildlife-friendly balcony—such as growing herbs and avoiding pesticides. Thanks to Lucy and her teammates’ continuous efforts, the once-barren lot has now turned into a lively mini forest, and more and more neighbors have begun to join their green campaign.
1．Which organization did Lucy join
2．When does Lucy do volunteer work
3．What does Lucy’s team give to residents
4．What made Lucy love the green cause
5．What does Lucy share at the community center

If you like unusual places, you should visit the Hebrides Islands（岛）. Not many people live on these islands in the northwest of Scotland. The land is not good for farming. It’s only good for keeping sheep. The winters are long, cold, and wet. It’s hard to make a living on the Hebrides, but for a visitor, these islands can be very special.
They’re not for everyone, however. Even in summer it is cool and windy. The water is too cold for swimming. There are no forests, and there are only a few trees and green fields. Instead of fields, there are just rocks（岩石）and small plants. The hills, too, are just piles of rocks. Sometimes the view（风景）looks like pictures of the moon.
But there is beauty in this place. From the beach you can often see all the way to the rocky hills. From the hills you can see far out to other islands and the open ocean（海洋）. The colors, too, are special. Blue is everywhere. It’s in the sky and in the ocean. It is in the tiny flowers that grow on the hills. In the spring there is also green in the hills. In the summer and fall the hills are more purple. Often the air is soft and gray with clouds and rain.
On these islands you can forget about the rest of the world. The evenings are quiet. The restaurants close early, and there isn’t any nightlife. Visitors stay at a guest house or a Bed and Breakfast. This is the best way to learn about life on the islands. The islanders are often friendly, and they like to talk.
If you want to meet islanders, you can also try the pubs（酒吧）or even the shops. People are in no hurry here. They like to chat about the weather or the fishing. There are also some tourist shops, but not many. They sell the usual tourist things. They also sell some beautiful clothes made of wool from the islands.
Do not come to the Hebrides for e to walk in the clean, cool e for the quiet beauty and for the views.
1．Are there many people living on the Hebrides Islands
2．How is the weather on the Hebrides Islands in summer
3．Where can you see other islands and the open ocean
4．What do the islanders like to chat about
5．What attracts（吸引）you most on the Hebrides Islands Why

After a difficult walk, Sam finally sat down by the pool, put away his compass (指南针) and lifted his field glasses. There they are! The mother swan was only a few feet away. She was sitting very close, not moving. The father swan was nearby. Both birds were listening and waiting. Both birds saw Sam, but they thought it didn’t matter. Sam stayed with these two great birds in the wild, just like old friends. That made him really happy.
In the morning, when the Sun was up in the sky, Sam focused his glasses on the nest (巢) again. At last, he saw a small head pushing through the mother’s feathers, the head of a baby swan. The baby climbed out of the nest. It had a grey head and neck, with soft fine feathers. Soon another baby appeared. Then another. Then the first one walked his way down into his mother’s feathers again for warmth. Then one tried to climb up his mother’s back, but her feathers were wet, and he fell off. The mother swan just sat and sat, enjoying her babies, watching them use their legs. One of the baby swans, more brave than the others, left the nest and walked around on the shore (岸边) of the island. When this happened, the mother swan stood up. It was time for her to lead her children to the water. The baby swans did as their mother did and soon found it easy to swim.
“One, two, three, four, five,” Sam counted. “One, two, three, four, five. Five babies, just as sure as I am alive! This is my lucky day.” The father swan, when he saw his children in the water, felt like he should act like a father. He began by making a speech.

The ocean is a huge and amazing world. It covers more than two-thirds of the Earth’s surface. The ocean is home to millions of living things, from tiny plankton to huge whales.
The ocean is very important to us. It provides us with many things. For example, we get fish, shrimp and other seafood from the ocean. Seafood is an important part of many people’s diet. The ocean also gives us salt, which we use to cook food.
Moreover, the ocean helps regulate (调节) the Earth’s climate. It absorbs (吸收) a lot of heat from the sun. This helps keep the Earth’s temperature stable. The ocean also produces a large amount of oxygen. About half of the oxygen we breathe comes from the ocean.
However, the ocean is facing many problems. Pollution is a big threat. People throw plastic bags, bottles and other rubbish into the ocean. This hurts marine animals. Many animals mistake plastic for food and eat it, which causes them to die. Overfishing is another problem. Some fishermen catch too many fish, which reduces the number of fish in the ocean.
We must protect the ocean. We can reduce plastic use by using reusable bags and bottles. We can also support sustainable fishing (可持续捕鱼). Governments should make stricter rules to stop ocean pollution. Everyone has a responsibility to protect the ocean. Let’s work together to keep the ocean clean and healthy.
1．How much of the Earth’s surface does the ocean cover
A．Less than one-third. B．More than two-thirds. C．About half. D．All of it.
2．What do we get from the ocean
① Seafood ② Salt ③ Oxygen ④ Plastic
A．①②③ B．①②④ C．①③④ D．②③④
3．Why is the ocean important to the Earth’s climate
A．It produces oxygen. B．It provides seafood.
C．It absorbs heat from the sun. D．It gives us salt.
4．What problems is the ocean facing
A．Pollution and overfishing. B．Pollution and cold weather.
C．Overfishing and lack of oxygen. D．Lack of salt and pollution.
5．What can we do to protect the ocean
A．Throw more plastic into the ocean. B．Ignore the ocean problems.
C．Catch as many fish as possible. D．Use reusable bags and bottles.
【答案】1．B 2．A 3．C 4．A 5．D
【导语】本文是一篇说明文。主要介绍了海洋的面积、对人类的贡献、在调节气候中的作用，以及当前面临的污染和过度捕捞等问题，最后呼吁人们保护海洋。
1．细节理解题。根据文章第一段“It covers more than two-thirds of the Earth’s surface.”可知，海洋覆盖了地球表面超过三分之二的面积。故选B。
2．细节理解题。根据文章第二段“we get fish, shrimp and other seafood from the ocean...The ocean also gives us salt”和第三段“The ocean also produces a large amount of oxygen.”可知，海洋为我们提供海鲜、盐和氧气。文中未提及海洋提供塑料。因此，我们能从海洋获得的是①②③。故选A。
3．细节理解题。根据文章第三段“It absorbs a lot of heat from the sun. This helps keep the Earth’s temperature stable.”可知，海洋对地球气候重要是因为它能吸收太阳的热量。故选C。
4．细节理解题。根据文章第四段“Pollution is a big threat.”以及“Overfishing is another problem.”可知，海洋面临污染和过度捕捞两大问题。故选A。

When we look at the Earth, we see many different things. Sometimes, you may hear people talk about landform and landscape. Are they the same thing Let’s find out!
A landform is a natural feature of the Earth’s surface. Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms. They are made by nature over a long, long time. For example, mountains are formed when huge pieces of the Earth’s surface push against (撞) each other. Valleys can be made by rivers cutting through the land little by little. Each landform has a name that tells us what it looks like and how it was formed. Scientists study landforms to learn about the history of the Earth.
A landscape, on the other hand, is what you see when you look at an area of land. It includes (包括) landforms, but it also has other things like plants, buildings, and lakes. Imagine standing on top of a hill. You can see green trees waving in the wind, a small village with houses, and a clear lake nearby. All these things together make up the landscape. A landscape can change rapidly. If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months.
Let’s take a forest in the mountains as an example. The mountain is the landform — it’s a natural feature of the Earth. But when you see the tall trees, hear the birds singing, and watch a little stream (溪流) running down the mountain, that’s the landscape.
So, the key difference is this: landform is about the natural shapes of the Earth, and landscape is about the whole view of an area, including both natural and man-made things. Next time you go on a trip, try to enjoy different landforms and describe (描述) the beautiful landscapes around you!
1．Which of the following is a landform
A．A newly-built bridge. B．A flat plain.
C．A group of trees. D．A small house.
2．What can we learn from the text about how mountains are formed
A．They are made by people building up the land.
B．They are formed when rivers cut through the land.
C．They are formed when the Earth’s plates push into each other.
D．They are formed by heavy rain and strong winds.
3．What does the underlined word “rapidly” in Paragraph 3 probably mean
A．Brightly. B．Quickly. C．Powerfully. D．Quietly.
4．What does “landscape” usually include
A．Only landforms. B．Only natural things.
C．Just man-made things. D．Landforms, trees, houses and lakes.
5．How does the writer explain the difference between landform and landscape
A．By telling stories. B．By listing numbers.
C．By giving examples. D．By asking questions.
【答案】1．B 2．C 3．B 4．D 5．C
【导语】本文是一篇说明文，介绍了地形和景观的区别。
1．细节理解题。根据“Think of big mountains that rise high up, low valleys (山谷) between hills, flat plains that go on and on, and sandy deserts. These are all landforms.”可知，高耸的大山、小山之间的低山谷，连绵不断的平原，还有沙漠，这些都是地形。故选B。
2．细节理解题。根据“mountains are formed when huge pieces of the Earth’s surface push against (撞) each other”可知，山是由地球表面的巨大板块相互推动而形成的。故选C。
3．词义猜测题。根据“If people build new buildings or cut down a lot of trees, the landscape will look different in just a few months.”可知，如果人们建造新的建筑物或砍伐大量的树木，景观将在短短几个月内看起来不同。因此景观的变化很快，rapidly和quickly都表示“快的，迅速的”。故选B。
4．细节理解题。根据“It includes (包括) landforms, but it also has other things like plants, buildings, and lakes.”可知，景观包括地形，但也有其他东西，如植物、建筑物和湖泊。故选D。
5．推理判断题。通读全文，结合文中关键词句“For example”“Let’s take a forest in the mountains as an example.”等可知，作者通过列举很多的事物来解释什么是地形和景观。故选C。

Lucy is a 16-year-old environmental volunteer who devotes herself to urban biodiversity protection. Last year, she signed up for the City Green Initiative, a local non-profit organization dedicated to building small ecological gardens and green corridors in crowded residential areas. Every Saturday morning, she meets her teammates at the community square, then they walk to the nearby abandoned lot to work. They clear the garbage, turn the soil, and plant native flowers and shrubs that are attractive to bees and butterflies. They also set up wooden bird feeders and water basins in the trees, hoping to draw more small birds to settle down. Besides these tasks, Lucy and her team regularly visit the neighborhood families to give out brochures. They teach residents how to sort household waste properly and how to recycle materials like plastic bottles and old newspapers into useful crafts.
Lucy’s interest in this meaningful cause started with a school lecture on sustainable living. The speaker shared how a tiny urban garden could provide shelter for dozens of species and improve the air quality around the community. Deeply moved, Lucy realized that even small daily actions could make a big difference to the environment. In her spare time, she also gives 15-minute talks at the community center, sharing practical tips on creating a wildlife-friendly balcony—such as growing herbs and avoiding pesticides. Thanks to Lucy and her teammates’ continuous efforts, the once-barren lot has now turned into a lively mini forest, and more and more neighbors have begun to join their green campaign.

But there is beauty in this place. From the beach you can often see all the way to the rocky hills. From the hills you can see far out to other islands and the open ocean（海洋）. The colors, too, are special. Blue is everywhere. It’s in the sky and in the ocean. It is in the tiny flowers that grow on the hills. In the spring there is also green in the hills. In the summer and fall the hills are more purple. Often the air is soft and gray with clouds and rain.
On these islands you can forget about the rest of the world. The evenings are quiet. The restaurants close early, and there isn’t any nightlife. Visitors stay at a guest house or a Bed and Breakfast. This is the best way to learn about life on the islands. The islanders are often friendly, and they like to talk.
If you want to meet islanders, you can also try the pubs（酒吧）or even the shops. People are in no hurry here. They like to chat about the weather or the fishing. There are also some tourist shops, but not many. They sell the usual tourist things. They also sell some beautiful clothes made of wool from the islands.
