Have you ever felt sad about the world when we saw the unkind behaviors (行为) or heard the unpleasant words? How can we have a comfortable    16    ? Does it depend on the government, the cleaners, the policemen and the teachers?

I like taking a walk around the lake near our home. One day, my daughter and I noticed how many litters were lying along the road. So the next day we    17    some big bags and started to collect litters along the way. There were plastic bottles, cups of tea drinks, snack bags, and    18    a school uniform (制服). By the time we finished walking a    19    of the lake, one of the bag was nearly full. We also cleaned several    20    that lead to the top of the hill. In the end, we collected three bags of litters.

Tired but happy, we stopped before we went home, and    21    one last look at the lake as the sun set. It looked more    22    than ever.

I know that sometimes the world’s problems can seem uncountable (数不清的) and you wonder whether you can help or not. In fact, the persons with warm hearts are also uncountable. So you are not    23   .

Every smile you share, every kind    24    you say, makes a difference. Every loving thought you think, every little thing you do for the flowers, the plants, the    25   , the humans—makes a difference in this world.

A

Gordon Hempton is an ecologist (生态学家). He has spent more than 40 years studying natural sounds and saving quiet. Why save quiet?

Today, man-made noise seems to be everywhere. It keeps us away from natural sounds and is bad for our health. However, quiet helps us a lot. Like nature, it helps us find peace in our minds. But the number of naturally quiet places is going down quickly.

Hempton became interested in natural sounds many years ago. One day, he was driving and got tired. So he stopped his car and found a place to rest. Then it began to rain heavily, and Hempton stayed and listened. “I stayed away from all man-made noise then and only heard the rain and animals making sounds,” he said. “I was surprised.”

In the following years, Hempton tried to find naturally quiet places and record natural sounds. In 2005, he found a dream place in a forest park. He did a lot to keep the quiet there. However, in 2018, man-made noise finally broke it. This made him realize that man-made noise breaks not only the quiet of this place but also that of the world. So, he started the Quiet Parks International (QPI ) in the same year. He wanted more people to take action to save quiet.

Now, Hempton and his team are busy saving quiet. Thanks to them, we can hear some of the world’s finest recordings of natural sounds and keep some best quiet places.

26．What is Paragraph 2 mainly about ________.

A healthy living place must be in balance (平衡). What does this stand for (代表)? Here it is. As a rule, rabbits eat plants. The rabbits keep the plants under control. Tigers eat rabbits. They make sure there are not too many rabbits. This is how the nature stays balanced.

But sometimes, things can get out of balance. A swamp (沼泽) in Florida is not in balance. What is the problem? There are too many large snakes. The snakes didn’t live in the swamp in the past. Why? Because some pet keepers let their pet snakes stay in the swamp. Their numbers become bigger and bigger. There are too many large snakes now. They are eating too much of the native wildlife (当地野生动物). So they are bad for the natural environment in the swamp. The snakes eat rabbits and other small animals. In the end, there is less food for large fish and wild cats. Now all of the wildlife in the swamp is becoming hungry.

To stop this problem, some people are trying to catch the snakes and take them away from the swamp. But it’s not easy because the snakes are very good at hiding. We need to be careful about what animals we bring into different environments so that we don’t break the balance of nature.

32．What is Paragraph 1 mainly about?

A．What the animals eat.                           B．Where the animals live.

C．How the nature stays balanced.              D．Why the nature needs balance.

33．A swamp in Florida is not in balance because __________.

A．too many large snakes appear                B．there is more native wildlife in it

C．large fish and wild cats are gone            D．many pet keepers come to live in it

34．What does the underlined words “this problem” refer to(指代)?

A．There is more food for small animals.

B．Some people are trying to catch the snakes.

C．The wildlife in the swamp is becoming hungry now.

D．The animals in Florida live in different environments.

35．What can be the best title for the text?

A．The balance of nature.                          B．A swamp in Florida.

C．The wildlife in Florida.                        D．The natural environment.

D

Have you heard of a cloud forest? Is it the same as a rainforest? Actually, it’s a very special kind of forest in cloudy mountains. There, clouds brush through trees and wet their leaves. Rain falls almost every day. Hundreds of mosses(苔藓) grow and cover everything like a soft, green coat.

Plants of cloud forests live in an unusual way. They grow on the branches of trees instead of on the ground. The air is very damp, so plants can get all the water they need from the fog and rain. They live on the high parts of trees so that they can get more light to be stronger.

There are many kinds of special animals in cloud forests. For example, tree kangaroos live in trees like monkeys. They use their long tails to balance just as monkeys do. Frogs have suckers(吸盘) on their toes so they can climb up trees and cross leaves easily. Many other special animals are waiting for us to discover, aren’t they?

Cloud forests are important to people. They give us healthy food crops, such as wild beans, peppers, tomatoes, potatoes and strawberries. Furthermore, they offer new medicine to treat cancer. Unluckily, the beautiful forests are in danger now. Why? Firstly, the climate is getting warmer, but plants and animals in cloud forests like to live where it’s cool. It’s difficult for them to find a proper place to live in. Secondly, people cut down many trees to plant crops or feed cows. The animals are losing their homes.

Once cloud forests are gone, there must be a huge loss to humans. Save the cloud forests before it’s too late!

36．How does the writer start the passage?

A．By telling stories.                                B．By giving examples.

C．By showing numbers.                           D．By asking questions.

37．What does the underlined word “damp” mean in paragraph 2?

A．Dry.                B．Sunny.                   C．Wet.                       D．Snowy.

38．According to the passage, many things live in cloud forests, including ________.

①mosses    ②blueberries    ③frogs with suckers

④monkeys    ⑤tree kangaroos

A．①②③            B．①③⑤                  C．②④⑤                   D．③④⑤

39．Which of the following is TRUE according to the passage?

A．We can use healthy food crops to make medicine for headache.

B．Hundreds of mosses grow because it’s always sunny in cloud forests.

C．The animals are losing their homes because people cut down many trees.

D．Plants need more water to be strong so they grow on the high parts of trees.
