You may think there is only sand (沙子) in the desert, but it is not the fact (事实). In the desert, there is a little rain, and it is not enough for most plants. But we can see some plants live in the desert. There is water in some places in the desert. We call these places oases (绿洲). People grow different kinds of crops (庄稼) there.
People also live outside the oases. They have camels (骆驼), sheep and other animals. These animals live on the desert plants and do not need much water.
The animals are useful to the desert people in many ways. They eat meat and drink milk and they use the camels to carry things like water and food. What’s more, the camels can even help people find water.
The desert people have to keep moving from place to place. They must always look for desert plants for their animals. When there is no more food for their animals, they move to another place. The desert people are friendly. They would be ready to help the people in need and give them food and water.

Green is more than just a color. It stands for health, youth and life. Now, it also means caring for the environment (环境).
People live in a “throw-away society”. They use things for a short time and then throw them away. Why does this happen First, there are too many choices. For example, if you are bored with your shoes after a few months, you may buy new ones and throw away the old ones. Second, many young people want the latest technology. They buy new phones and throw away the old ones. This leads to more rubbish.
Recycling is easy. You can be the “Head of Recycling” in your family. Learn what can be recycled and find a place to keep them. Encourage (鼓励) everyone to think before throwing things away — can they be reused or recycled
Being green can be fun. Look at your backyard. Can you plant a tree or start a small garden If so, get your hands dirty. You will be proud to see your tree grow and your garden produce tomatoes or strawberries.

①Most people know that trees are good for us. They give us shade on sunny days and make our world beautiful with their green leaves. But trees do much more than that. They also help to make the air around us clean and healthy, which is very important for everyone.
②First, trees take in bad air and give out good air. The good air is called oxygen (氧气). We need oxygen to breathe (呼吸) and stay healthy every day. Trees make this happen quietly, all year round. They are like nature’s air cleaners.
③Second, trees can stop dust (灰尘) and small dirty things in the air. Their leaves are like small nets that catch these things. When dust comes with the wind, it gets stuck on the leaves. Later, when it rains, the water washes the dust away. This helps to keep the air clean for us to breathe.
④Third, trees can make the air cooler on hot days. When the sun is strong, trees give out water from their leaves into the air. This makes the air around them feel fresh and cool. It is nicer to walk under trees in summer because of this.
⑤Planting trees is an easy and useful way to help our Earth. Trees work hard every day to clean the air for us. We can plant trees in our school, in parks, or near our homes. Let’s plant more trees and take good care of them, because they take good care of us.
21．What is the passage mainly about
A．Why trees are beautiful. B．How trees help clean the air.
C．Where to plant trees. D．What trees eat.
22．What do trees give out that we need to breathe
A．Dust. B．Shade. C．Oxygen. D．Water.
23．Why does the writer talk about “hot days” in Paragraph 4
A．To tell us to drink more water.
B．To explain how trees help us feel cooler.
C．To say trees need more sun in summer.
D．To show that trees grow better in hot weather.
24．What can we learn from the passage
A．Trees are only useful in parks.
B．Trees can help us save money.
C．Planting trees is good for people and the Earth.
D．Trees make the air hotter in summer.
25．What’s the structure of the passage (①=Paragraph 1, ②=Paragraph 2…)
A．①-②③④-⑤ B．①②-③④-⑤ C．①②③-④⑤ D．①-②③④⑤
D
Scientists have some important news. The year 2025 was one of the warmest years ever recorded! A climate (气候) centre in China discovered this after studying weather data (数据) from all over the world for many years. The data clearly shows our earth is getting hotter and hotter, and this trend (趋势) is not slowing down.
A key reason for this warming is the very warm Arctic. Temperatures at the North and South poles keep breaking records every year. When the ice there melts, it not only makes sea levels rise but also changes the weather: Some places may become too hot to live in comfortably, some areas may get too dry and have no enough water for farming, and others may face very big storms.
This news makes all of us focus on environmental problems. We need to protect our planet right now, and everyone can play a part. We can help by saving energy — like turning off lights when we leave a room, planting more trees to take in carbon dioxide, and using less plastic (塑料) bags and bottles because plastic takes hundreds of years to break down. Even small things, such as walking or riding bikes instead of taking cars for short trips, matter a lot. Every small action is important for our earth, and if we work together, we can make the planet a healthier home.
26．What’s the theme (主题) of the passage
A．Nature. B．Culture. C．History. D．Sports.
27．What does the underlined word “melts” in Paragraph 2 mean
A．Turns into air. B．Turns into land.
C．Turns into wind. D．Turns into water.
28．What will life on earth be like when the ice at the poles goes on melting
A．Tiring. B．Happy. C．Terrible. D．Colourful.
29．How can we save energy in daily life according to the passage
①Plant more vegetables. ②Use less plastic bottles.
③Don’t drive cars for short trips. ④Turn off water when others use it.
⑤Turn off lights when leaving a room.
A．①②⑤ B．②③⑤ C．②③④⑤ D．①②③④⑤
30．What’s the writer’s purpose in writing the passage
A．To make us know big storms are really awful.
B．To call on us to work together to protect the planet.
C．To show how bad plastic is bad for the environment.
D．To tell us the Arctic is the coldest place on earth.

Studies suggest that as many as half of all migratory birds (候鸟) do not make it back to spring and summer grounds. Migratory birds need our help now more than ever. Here are some things you can do in your home or garden to help them.
Make windows safer
Windows are deadly for birds. At night, lighted windows attract (吸引) and kill migratory birds. During the daytime, windows reflect (映出) trees or the sky, encouraging birds to fly into them. You can turn off lights at night, and use window tape (胶带) to keep birds away from windows during the day.
Keep cats indoors
Billions of birds die in the U. S. and Canada each year when they are caught by cats. Keeping cats indoors is good for the cats and the local wildlife.
Grow native plants
From window boxes to large gardens, the plants that you grow can make a difference to birds. Native (本地) plants support more insects (昆虫), so migratory birds have more to eat. Besides, don’t use pesticides (杀虫剂) in your garden.
66．Why do migratory birds need our help

【导语】本文讲述了Scott和家人、同学在世界地球日植树的故事。Scott邀请同学加入，大家在卡片上写字并粘在树上，通过实际行动向人们传递保护环境的重要性。
【解析】1．句意：今年，Scott想让一些同学加入他们，在地球日一起植树。
根据前文“Scott and his family are in a planting club.”以及后文“plant trees on Earth Day”可知，Scott想邀请同学“加入”他们的植树活动。join意为“加入”，符合语境。choose意为“选择”，get意为“得到”，take意为“拿”，均不符合“邀请同学一起参与”的语境。
2．句意：所以他告诉了他们这件事。
根据前文“Scott wants some of the classmates to join them”以及后文“Scott asks his classmates”可知，Scott是“告诉”同学们关于植树的事。tells意为“告诉”，符合语境。watches意为“观看”，looks意为“看”，finds意为“发现”，均不能接双宾语结构“tell sb about sth”。
3．句意：“你们想种什么树？”Scott问道。
根据后文“Well, all trees.”可知，回答的是“什么样的树”，因此提问应用what。what意为“什么”，符合语境。who意为“谁”，when意为“什么时候”，how意为“怎样”，均不能与“trees”构成合理的提问内容。
4．句意：它们对人们有益。
根据常识及上下文，植树对环境有益，最终受益的是“人们”。people意为“人们”，符合语境。dogs意为“狗”，food意为“食物”，buildings意为“建筑”，均不符合“植树对环境有益”的逻辑。
5．句意：我们可以制作一些漂亮的卡片，然后把它们粘在树上。
根据后文“stick them on the trees”可知，需要先“制作”卡片才能粘贴。make意为“制作”，符合语境。change意为“改变”，play意为“玩耍”，collect意为“收集”，均不能与“cards”和“stick”构成制作、粘贴的合理动作链。
6．句意：Scott的同学们在卡片上写了一些话。
根据后文“some words on the cards”可知，同学们“写”了话在卡片上。write意为“写”，符合语境。think意为“思考”，notice意为“注意”，speak意为“说话”，均不能与“words on the cards”构成合理的动宾搭配。
7．句意：他们非常开心，因为他们可以在大自然中种树。
根据后文“they can plant trees in nature”可知，能在大自然中种树让他们感到“开心”。happy意为“开心的”，符合语境。clever意为“聪明的”，busy意为“忙碌的”，interested意为“感兴趣的”，均不符合“能种树”带来的情感反应。
8．句意：Scott和他的父母教他们种树。
根据前文“Scott goes to the park with his parents and his classmates”以及“Scott and his parents teach”可知，教的对象是“同学们”，即“他们”。them意为“他们”，符合语境。me意为“我”，him意为“他”，us意为“我们”，均与“classmates”的指代不符。
9．句意：并且最后他们把他们的卡片粘在树上。
根据前文“We can make some nice cards and stick them on the trees.”可知，他们制作了卡片，最后要粘贴的是“卡片”。cards意为“卡片”，符合语境。photo意为“照片”，maps意为“地图”，books意为“书”，均与“stick on the trees”的动作不符。
10．句意：而且他们也希望人们了解环境的重要性。
根据前文“They want people to plant trees.”以及后文“want people to know the importance of the environment”可知，前后是并列关系，表示“也”希望人们了解环境的重要性。also意为“也”，常位于句中，符合语境。very意为“非常”，too意为“也”（常位于句末），only意为“仅仅”，均不符合此处句中并列的语法位置。

13．第二段指出“These animals live on the desert plants and do not need much water.”以及第三段提到骆驼可以运水可知，骆驼不需要太多水，但能运水且吃植物。
14．第四段“The desert people have to keep moving from place to place. They must always look for desert plants for their animals.”表明，沙漠居民需要不断迁徙寻找食物和水，生活条件艰苦。
15．文章第一段介绍了沙漠中的绿洲，后几段重点介绍了沙漠居民依赖的动物及其迁徙的生活方式。“Oases and the desert people’s lives”涵盖了绿洲环境和居民生活两个主要方面。
16．C 17．A 18．B 19．A 20．B
【导语】本文是一篇说明文，介绍了绿色的环保含义，指出了一次性消费的问题，并倡导人们通过回收、种植等方式践行环保。

【导语】本文主要介绍了树木对净化空气和环境的重要作用，分别从产生氧气、阻挡灰尘和夏季降温三个方面具体阐述，最后呼吁人们植树护树。
【解析】21．根据第一段中的“But trees do much more than that. They also help to make the air around us clean and healthy, which is very important for everyone.”以及后文分别阐述树木的三种净化作用可知，文章主要介绍了树木如何帮助净化空气。
22．根据第二段中的“First, trees take in bad air and give out good air. The good air is called oxygen (氧气). We need oxygen to breathe (呼吸) and stay healthy every day.”可知，树木释放出我们呼吸所需要的氧气。
23．根据第四段中的“Third, trees can make the air cooler on hot days. When the sun is strong, trees give out water from their leaves into the air. This makes the air around them feel fresh and cool.”可知，第四段中心是树木在炎热天气降温，举热天例子解释树木如何让空气变凉爽，即作者提到“hot days”是为了解释树木如何帮助人们感觉凉爽。
24．根据第五段中的“Planting trees is an easy and useful way to help our Earth. Trees work hard every day to clean the air for us.”以及全文可知，植树对人类和地球都有益。
25．通读文章可知：第①段为总起：引入主题，指出树木能净化空气；第②、③、④段分别用“First, Second, Third”并列说明了树木净化空气的三个不同具体作用；第⑤段为总结：提出倡议，呼吁植树。其篇章结构为“总-分-总”，即①-②③④-⑤，对应选项A。
26．A 27．D 28．C 29．B 30．B
【导语】本文是一篇说明文，主要介绍了2025年是有记录以来最热的年份之一，又介绍了地球变暖的原因以及保护地球的行动建议。
【解析】26．主旨大意题。根据第一段“The year 2025 was one of the warmest years ever recorded! A climate (气候) centre in China discovered this after studying weather data (数据) from all over the world for many years.”可知，本文主题属于自然范畴。
27．词句猜测题。根据“it not only makes sea levels rise”可知，此处“melts”指的是“冰化成水”,与“turn into water”意思相符。
28．推理判断题。根据第二段“… but also changes the weather; Some places may become too hot to live in comfortably, some areas may get too dry and have no enough water for farming, and others may face very big storms.”可推知，两极的冰持续融化会使人们的生活很糟糕。
29．细节理解题。根据第三段“We can help by saving energy — like turning off lights when we leave a room, planting more trees to take in carbon dioxide, and using less plastic (塑料) bags and bottles because plastic takes hundreds of years to break down. Even small things, such as walking or riding bikes instead of taking cars for short trips, matter a lot.”可知，日常生活中可以节约能源的方法有少用塑料瓶、短途旅行不开车和离开房间要关灯。
30．推理判断题。文章最后一段明确呼吁“We need to protect our planet right now, and everyone can play a part ... if we work together, we can make the planet a healthier home.”，核心目的是号召大家共同保护地球。
31．E 32．A 33．F 34．C 35．D
