二、阅读理解（共20小题，每小题2分，满分40分）

第一节（共15小题，每小题2分，满分30分）

阅读以下三篇短文，从每小题所给的四个选项中，选出一个与短文内容相符的最佳选项。

A

The Yellow River starts in the Qinghai-Tibet Plateau (青藏高原) and runs eastward across China. On its way, it passes through the Loess Plateau (黄土高原)—a place with a lot of soft soil and few plants. When it rains, the soil is easily washed into the river, turning the water brown. It looks like “half water, half sand”. So the Yellow River has been famous for its brown water for many years.

But in 2025, something amazing happened: parts of the river became clear! People saw clear water at Hukou Waterfall in Shaanxi Province. This surprised everyone.

▲ First, less rain fell in early 2025. The Loess Plateau got 35% less rain than usual. Less rain means less soil is washed into the river. Second, people have worked for years to protect the land. They planted trees and built small dams (大坝) to stop soil from being washed away. Today, green plants grow on nearly 63% of the Loess Plateau. In 1999, it was only 31%. That’s why its water is clearer today!

However, the clear water brings both hope and new challenges. On the positive side, more fish have returned, and the risk of dangerous floods may be reduced. But clear water also has its downsides: it can wear away (磨损) riverbanks faster, and less soil getting to the river means that wetlands by the river are getting smaller.

Nature and humans need to work together for a better future. Scientists are now studying how to keep the river healthy while enjoying its green and clear water. People near the river are also learning new ways to farm so that they won’t harm the land or the water. Everyone agrees that protecting the Yellow River is important for both its beauty and its role in history.

16．People were surprised that the Yellow River ______.

A．got more water

B．became much cleaner

C．looked brown for many years

D．ended in the Qinghai-Tibet Plateau

17．Which of the following can be put in “▲”?

A．When did this happen?

B．How did it affect people?

C．Cleaning the water is important.

D．There are two main reasons for the clean water.

18．What percent of the Loess Plateau has green plants today?

A．Only 31%.B．Around 32%.C．About 35%.D．Nearly 63%.

19．What positive effect of the clearer water is mentioned in the passage?

A．It’s helpful for the fish.

B．It makes no real difference.

C．It brings little bad influence.

D．It’s good for the riverbank.

20．What is the main idea of the passage?

A．The Yellow River is famous for its beautiful scenery.

B．People find new ways to make the Yellow River clearer.

C．Why the Yellow River became clear and how to protect it.

D．Farming near the Yellow River always harms the land and water.

B

Last weekend, I went camping after a long time of tiring work. The trip let me enjoy the clear lake and beautiful views in the forest. I felt the difference at once. I relaxed. I came home feeling rested. Going camping became a way to reduce the worry in my life.

I not only got a nice weekend, but also experienced the benefits of nature, which was good for my mental health. Research has found that as few as five minutes in nature can be helpful for people to reduce worry and feel happier. This means that we can get relaxed and feel better from stepping outside right away.

Even though sometimes we are unable to put our whole body and mind into nature, we can still find chances to relax in nature. We can take a five-minute break in a small park near our house or take a moment to sit under a big tree. We'll find them useful. Our better feelings in later life can demonstrate the active influence of nature.

Besides simply spending more time outdoors, think about how we can enjoy nature even if we are too busy. Listen to recorded bird songs or rainstorms instead of music. Bring green plants or pictures of natural beauty into our home. Although bringing nature indoors is quite different from a real outdoor experience, we can still feel nature and experience better feelings.

Being in nature doesn’t ask anything of us. Slow down, go outside, and notice what’s around us. Listen, touch and smell, and we will really notice the benefit in our emotions.

Yeshe Dolkar, 15, lives in Nangqian County, Qinghai. On a cold snowy day, she saw two snow leopards near the headwaters of the Lancang River. “They have blue-green eyes and long fluffy (蓬松的) tails with black spots (斑点) all over the body. They look so cool!” Yeshe Dolkar said.

Since the mid-20th century, the area of snow, grasslands and lakes in Sanjiangyuan has become smaller because of climate change and human activities. Wild animals like snow leopards have been endangered.

On 22 July 2000, China set up Sanjiangyuan National Nature Reserve to better protect the area and the wildlife there. In these years, the population of wild animals has been rising.

Local people have also learned how to protect Sanjiangyuan over the years. In Nangqian County, people used to leave dirty bags behind in grasslands. But now things have changed. According to Palden Wangchuk, a 22-year-old young man, people regularly pick up waste on the grasslands and take it down the mountains. “The grasslands have put on a new look,” he said. “As young people, we should protect our home and continue to live together with nature in harmony (和谐),” Palden Wangchuk added.

36．means

【解析】句意：交流的方式已经改善了很多。句中“the means of...”为固定搭配，意为“……的方式、手段”，且谓语动词have为复数形式，主语用复数，mean的名词复数形式是means，故填means。

37．worse

【解析】句意：如果你不按时吃药，你的感冒会变得更糟。空格前“get”为连系动词，意为“变得”，后需接形容词作表语。根据后半句“if you don’t take medicine on time”的语境逻辑可知，不按时吃药会导致病情比现在更糟，暗含与现在的状况进行对比的意味，要求使用形容词bad的不规则比较级worse。故填worse。

38．the most interesting

43．ocean

【解析】句意：海洋覆盖了地球表面70%以上的面积。根据中文提示可知，空格处应用ocean“海洋”。这个词是名词，在句中作主语，句中谓语动词“covers”是第三人称单数形式，说明主语是单数概念，这里指的是地球上的海洋整体，因此用单数形式即可。故填ocean。

44．surface

【解析】句意：湖面平静而反光。句中“The”后需要填入名词，作句子的主语。“表面”对应的英文单词是 surface，故填surface。

Dear Tim,

I’m writing to tell you something about one of the greatest wonders of the natural world in China—the Yarlung Tsangpo Grand Canyon. It’s in Xizang, China. And it is the deepest canyon in the world, about 505 kilometres long. The deepest depth of it reaches around 6 kilometres.

As a place that all nature lovers want to visit, the Yarlung Tsangpo Grand Canyon is home to thousands of plants and animals. It’s called “the plant museum” and “the animal kingdom”. The best time to visit it is spring and summer.

I’m sure you will have a great time there.

Yours,

Wang Haoyu
