第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。
A
Trees are not just beautiful plants; they are essential for life on Earth. They play a crucial role in keeping our environment healthy.
Trees absorb carbon dioxide, a gas that contributes to global warming, and release oxygen, which we need to breathe. They also help keep the soil in place, preventing erosion and floods. In addition, forests provide habitats for countless species of animals and plants.
However, many trees are being cut down every day. Some are cut for wood to make furniture, paper, and other products. Others are cleared to make room for buildings, farms, and roads. This deforestation has serious consequences, such as climate change, loss of wildlife habitats, and soil degradation.
To protect our planet, we need to plant more trees and stop illegal logging. Everyone can help by using less paper, recycling, and supporting policies that protect forests. Trees are our friends, and we should do everything we can to protect them.
26．Why are trees essential for life on Earth
A．Because they are beautiful.
B．Because they can be made into furniture.

Saihanba is China’s largest forest. It lies on the south of Inner Mongolia Autonomous Region (内蒙古自治区). Saihanba means “beautiful and high mountains”.
Around the 10th century, the rulers of the Liao Dynasty (916—1125) made it a royal (皇家的) hunting place because it was home to beautiful forests, green grasslands, clear lakes and different kinds of wild animals. Emperor Kangxi of the Qing Dynasty (1644—1911) liked Saihanba so much that he made hunting there a royal festival. The royal festival finally stopped in 1860 because of no money and it had to be open to the public. After that, the cutting down of trees and wild fires changed green Saihanba into gray deserts. By the 1950s, the beauty of Saihanba had completely disappeared with only one tree left. The tree is now famous as “the Tree of Honor”.
On seeing the tree, Chinese scientists made up their minds and dreamt of restoring Saihanba. In February, 1962, the plans were made and more than 120 foresters joined 242 local people in Saihanba to begin rebuilding it. Over the next 55 years, those first tree-planters fought against many difficulties to continue planting trees. After their death, their children and relatives followed their footsteps and went on with their hard work of planting trees.
Today, the scientists’ dream has come true and beautiful grassland and flowers appear again around the tree of honor. Chinese people successfully changed Saihanba in the past half-century.
31．What’s the right order of events (事件) given in Paragraph 2
①Saihanba became a royal hunting place.
②Saihanba was a desert and disappeared.
③Saihanba wasn’t closed to the public any more.
④Saihanba turned into the place for royal hunting festivals.

Scientists found plants could “talk”. Lilach Hadany and her team recorded (录音) some plants in different places. Their recordings showed that the plants made some sounds.
After the scientists changed their recordings, people could hear plants clicking (咔嗒) clearly. They also found the plants hardly clicked when they had enough water. As their soil (土壤) got drier, they clicked more and more.
When the scientists cut off a part of the plants, the plants also clicked more. But the clicking wasn’t the same as when the plants needed water. The plants made more sounds when they felt bad. Because of these findings, the scientists thought that they can use a plant’s sounds to find out when it needs help, and what problem it is having.
Some questions come with the study. One important question is: Do plants make sounds to talk with each other Other studies showed that plants seem to talk in some ways. If some animals are eating the plants, the plants will send chemicals into the air. Soon, nearby plants start to make other chemicals that don’t taste good to the animals. Maybe the sounds could work in the same way. Another question is: Is anything listening to the plants Hadany says that she and her team will study if plants or animals will answer the clicking sounds of the plants.
The study changed people’s ideas about plants. Hadany says, “Even in a quiet place, there are sounds that we don’t hear, and those sounds have things to tell.”
36．What does the underlined word “hardly” in Paragraph 2 mean
A．sometimes B．Always C．Often D．almost never
37．Which of the following is TRUE according to the passage
A．Plants clicked more when the soil was too dry.
B．Plants made no sound when scientists cut them off.
C．Plants made sound to talk when animals were eating them.
D．People couldn’t hear plants’ sounds because they were too quiet.
38．What will Hadany and her team study next
A．How do the plants make the clicking sounds
B．Do plants make sounds to talk with other plants
C．Will plants or animals answer plants’ clicking sounds
D．What can they do to change people’s ideas about plants
39．Which one can be the title for the article
A．Plants can “talk”. B．Plants on Earth C．Beautiful music D．The sound of nature
40．We can read this passage from a _________.
A．fairy story B．science magazine C．news report D．travel guide

Why do plants grow in some places and not in others Some lands have so many plants. 41
To grow, plants need some things. One is warmth. In very cold places almost (几乎) nothing grows. 42 In very dry parts of the earth only some unusual (罕见的) plants can grow. That’s why dry deserts everywhere have almost no trees or grass.
Plants need to have a place to put down their roots (根) and grow. 43 If the town is on hard lands, the plants here can only find the soils between the cracks of stones to grow in.
44 What will happen if we try to make things grow on the sandy beach A few plants, such as beach grass, will grow in sand. 45 Even if (即使) the weather is warm and we water the plants every day, many of them will die (死) because the sand on this beach has almost no food for plants.

B．But most plants won’t grow.
C．Plants must have food to grow.

A team found that plants can make sounds.
The team recorded (录制) tomato plants at different times. It showed that the plants made ultrasound (超声波). Humans could only hear them with the help of a computer.
As the team studied the sounds, they started to find some interesting facts. Plants made different sounds at different times. They seldom made sounds when they had enough water. But when the soil got dry, they made more sounds. The team also found that plants made sounds when they got hurt. When the team cut a leaf from the plants, the plants also made sounds. But the sounds weren’t the same as when the plants needed water.
The team developed a computer AI system (系统). They used it to tell different kinds of sounds. It was able to find the difference between thirsty (口渴的) plants and plants with cuts. Maybe one day we can use these sounds to find out a plant’s problem.

Why Are Plants Important
Plants are very important for people, animals and the environment. Now let me introduce the importance of plants to you.
First of all, for people, plants can give us basic needs. We can use trees and plants in many ways. We can get a lot of food from plants. Some plants can be made into medicine and clothing. Second, plants are also important for animals. Many animals live in the forest and they eat the fruit from plants and trees. Third, trees and other plants help clean the air, so we can breathe the fresh air every day. They can not only stop the wind from blowing the soil away but also stop the water from washing the soil away.
In a word, all living things cannot live without plants. The plants are important. Let’s protect plants and make our world greener.
