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.

From the deepest forests to our towns and cities, trees are all around us. We share our world with trees. They are our silent friends, but we often overlook them.
In fact, trees are very important for all living things on Earth. To begin with, forests are a safe place for animals, insects and plants to live. Trees are also good for us humans because they take in greenhouse gases like CO and produce oxygen. This means they help create a clean environment for everyone on this planet.
Trees make our lives more convenient. Many of the things around us, such as paper and pencils, come from trees. Just look around your room—a lot of the furniture is made of wood. Trees also provide us with delicious fruit and wonderful drinks. For example, we can make tea from the leaves of the tea tree.
Trees do so much for us. We can’t imagine a world without them. However, humans are not treating trees in a kind way. We are cutting down forests all around the world. We are polluting the water and the air, and this harms trees. All these things are a big problem. We need to do more to protect trees and save our planet.

C
Mangroves (红树林) are special trees that grow in coastal areas. They look like “guardians” of the sea—their long roots not only hold the soil together but also protect coasts from storms and waves. Besides, these forests are home to many animals, such as fish, birds and crabs.
However, mangroves are in danger now. Over the past 50 years, about 35% of the world’s mangroves have disappeared. One main reason is human activities: people cut down mangroves to build farms, ports or houses. Another reason is pollution—oil spills and plastic waste damage the water and kill the plants and animals living there.
Luckily, more and more countries have realized the importance of mangroves and started to protect them. In China, for example, local governments set up nature reserves to stop people from cutting down the trees. Volunteers also help clean the beaches near mangroves and teach visitors about their role. With these efforts, some mangrove areas are growing again.
Mangroves show us how closely humans and nature are connected. To save them is to protect our own home. We should all do our part to keep the balance between humans and nature.
36．What do mangroves’ long roots NOT do
A．Hold the soil together. B．Protect coasts from storms.
C．Provide food for fish. D．Create shade for smaller plants.
37．Why have many mangroves disappeared

38．What does China do to protect mangroves
A．Build more ports near mangroves. B．Let volunteers cut down dead trees.
C．Set up nature reserves. D．Stop visitors from entering mangrove areas.
39．What can we learn from the passage
A．Mangroves only live in China. B．Humans and nature depend on each other.
C．All mangroves will disappear soon. D．Plastic waste helps mangroves grow.
40．What is the main idea of the passage
A．To introduce the importance of mangroves and ways to protect them.
B．To explain how mangroves grow in coastal areas.
C．To describe the animals living in mangroves.
D．To show the history of mangrove protection.

考查副词辨析。Actually实际上；Hardly几乎不；Suddenly突然；Really真正地。根据“Lucy hasn’t finished her homework”以及“she didn’t write a word at all”可知，此处指实际上她一个字也没写，所以应该用Actually。故选A。
4．B
【解析】句意：如果你感到孤独，尽管和我交谈。
考查动词短语。feel free to do sth.“尽管做某事”，所以空处用动词不定式形式。故选B。

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.

From the deepest forests to our towns and cities, trees are all around us. We share our world with trees. They are our silent friends, but we often overlook them.
In fact, trees are very important for all living things on Earth. To begin with, forests are a safe place for animals, insects and plants to live. Trees are also good for us humans because they take in greenhouse gases like CO and produce oxygen. This means they help create a clean environment for everyone on this planet.
Trees make our lives more convenient. Many of the things around us, such as paper and pencils, come from trees. Just look around your room—a lot of the furniture is made of wood. Trees also provide us with delicious fruit and wonderful drinks. For example, we can make tea from the leaves of the tea tree.
Trees do so much for us. We can’t imagine a world without them. However, humans are not treating trees in a kind way. We are cutting down forests all around the world. We are polluting the water and the air, and this harms trees. All these things are a big problem. We need to do more to protect trees and save our planet.

Mangroves (红树林) are special trees that grow in coastal areas. They look like “guardians” of the sea—their long roots not only hold the soil together but also protect coasts from storms and waves. Besides, these forests are home to many animals, such as fish, birds and crabs.
However, mangroves are in danger now. Over the past 50 years, about 35% of the world’s mangroves have disappeared. One main reason is human activities: people cut down mangroves to build farms, ports or houses. Another reason is pollution—oil spills and plastic waste damage the water and kill the plants and animals living there.
Luckily, more and more countries have realized the importance of mangroves and started to protect them. In China, for example, local governments set up nature reserves to stop people from cutting down the trees. Volunteers also help clean the beaches near mangroves and teach visitors about their role. With these efforts, some mangrove areas are growing again.
Mangroves show us how closely humans and nature are connected. To save them is to protect our own home. We should all do our part to keep the balance between humans and nature.

C．Set up nature reserves. D．Stop visitors from entering mangrove areas.
39．What can we learn from the passage
A．Mangroves only live in China. B．Humans and nature depend on each other.
C．All mangroves will disappear soon. D．Plastic waste helps mangroves grow.
40．What is the main idea of the passage
A．To introduce the importance of mangroves and ways to protect them.
B．To explain how mangroves grow in coastal areas.
C．To describe the animals living in mangroves.
D．To show the history of mangrove protection.

On March 1st, 2024, three Spain-born pandas, Chulina, Jiu Jiu and YouYou, arrived in China after a 12-hour flight with their parents Bing Xing and Hua Zui Ba. All the pandas are in good health.
The panda parents started their life at the Madrid Zoo of Spain in 2007. Since then, they have given birth to six baby pandas there. Their three older children, born in 2010 and 2013, have already returned to China. Of the three younger ones, Chulina was born in 2016 and a pair of twins, You You and Jiu Jiu, were born in 2021.
Before the pandas returned to China, the Madrid Zoo held a party to say goodbye to this panda family. At the ceremony, Madrid’s mayor (市长) said, “Saying goodbye is sad, which is like saying goodbye to loved ones when they are going on a trip, but I’m also joyful because we have already had a close relationship with the cute pandas.”
The Madrid Zoo received the first pair of pandas from China in 1978. Four years later, Chu Lin was born, the first baby panda born in captivity (被圈养的) in Europe.
Over the years, workers in Madrid Zoo have learned to care for, protect and raise pandas with the help of Chinese and Spanish experts. “Through the pandas, I can learn a lot about the Chinese culture,” said Alejandro Cubrera, one of the men workers taking care of pandas. “They all have Chinese names and I know their meanings.

参考答案及试题解析
1．D
【解析】句意：——我们队在校运动会上表现很好。——是的，你们跑得最快。
考查副词最高级。fast快；faster更快；most fast错误表达；the fastest最快。根据答句中“of all”可知，比较范围是“所有人中”，需用最高级形式。故选D。
2．A
【解析】句意：——你认为世界上哪种动物是最快的？——我认为是猎豹。它能跑每小时110多公里。
考查形容词最高级辨析。the fastest最快的；the most beautiful最漂亮的；the heaviest最重的；the largest最大的。根据答语“It can run over 110 kilometers per hour.”可知，猎豹每小时能跑110多公里，强调的是速度，因此问句应询问“最快的动物”。故选A。
3．A
【解析】句意：露西还没有完成她的作业。实际上，她一个字也没写。
考查副词辨析。Actually实际上；Hardly几乎不；Suddenly突然；Really真正地。根据“Lucy hasn’t finished her homework”以及“she didn’t write a word at all”可知，此处指实际上她一个字也没写，所以应该用Actually。故选A。
4．B
【解析】句意：如果你感到孤独，尽管和我交谈。
考查动词短语。feel free to do sth.“尽管做某事”，所以空处用动词不定式形式。故选B。
5．A
【解析】句意：清明节不仅是一个传统节日，而且也体现了天气与植物生长之间的关系。
考查名词辨析。connection连接；choice选择；difference差异；situation情况。根据“Qingming is not only a traditional festival, but also shows the…between weather and plant growth”可知，清明节作为节气，强调天气与植物生长之间的联系。故选A。
6．B
【解析】句意：我的电脑比杰克的便宜得多。
考查比较级修饰词及名词所有格。根据“My computer is…cheaper than….”可知，第一空后cheaper是比较级，需用much等词修饰表示程度，而more不能修饰比较级；第二空表示杰克的电脑，应用名词所有格Jack’s。故选B。
7．D
【解析】句意：保罗承诺昨天傍晚7点在火车站接我。然而，他直到8点才出现。
考查动词时态。doesn’t appear没有出现，一般现在时；isn’t appearing没有出现，现在进行时；won’t appear将不出现，一般将来时；didn’t appear没有出现，一般过去时。根据时间状语“yesterday evening”，事件发生在过去，需使用一般过去时描述动作“未出现”。故选D。
8．D
【解析】句意：保护环境对我们来说很重要。
考查固定句型“It’s+adj+for sb to do sth”的用法。根据“It’s important…us…the environment.”可知，此处是“It’s+adj+for sb to do sth”句型，意为“对某人来说做某事是……的”，其中it是形式主语，不定式是真正的主语。故选D。
9．C
【解析】句意：夏天我们应该戴太阳镜保护眼睛免受强烈的阳光照射。
考查动词辨析。prevent防止；provide提供；protect保护；practice练习。根据空后的“our eyes from the strong sunlight”可知，此处表示保护眼睛免受强烈的阳光照射。短语protect...from...意为“保护……免受……”。故选C。

【解析】句意：我非常失望，因为我没有买到音乐会的票。
考查形容词辨析。disappointed失望的，修饰人；disappointing令人失望的，修饰事物；excited激动的，修饰人；exciting令人激动的，修饰事物。空处用于修饰主语“I”（即修饰人），所以排除选项B和D；结合“because I didn’t get tickets for the concert”可推知，由于没买到音乐会的票，所以“我”很失望。故选A。
11．A 12．B 13．B 14．A 15．D 16．C 17．B 18．D 19．D 20．B 21．D 22．A 23．C 24．B 25．D
