三、阅读理解
Let’s clean up the ocean together!
We all know it’s important to have dreams. However, to make the dreams come true is not an easy thing. A young Dutch (荷兰的) man named Boyan enjoys working hard to make his dreams come true.
When Boyan was 16, he went diving (潜水) in Greece. He was shocked to see more plastic bags than fish in the sea. The boy made up his mind to clean up the ocean. However, everyone told him that there was nothing he could do. The teenager didn’t give up. He spent several months studying plastic pollution. Finally, he came up with a science project using floating barriers (漂浮的栅栏) to collect the waste. That is to say, instead of using nets and ships to collect the plastic bags, the barriers can make the plastic bags come together with the help of natural ocean currents (洋流) and winds. What’s more, the collected plastic bags can be recycled and made into products or oil.
Boyan won prizes for the project, but that was not enough for him: he wanted to make it a reality. Then he set up The Ocean Cleanup. Together with scientists, engineers and volunteers, the young man is working hard to clean up the ocean to make our world a better place.
Would you like to join them
41．Where does Boyan come from
A．Holland. B．Greece. C．England. D．Asia.
42．In this passage, the underlined word “waste” refers to ________.
A．nets B．barriers C．plastic bags D．currents
43．The Ocean Cleanup is ________.
A．a group B．a club C．a company D．a school
44．What is NOT true according to the passage
A．There were more plastic bags than fish in the sea.
B．There was nothing Boyan could do with the plastic pollution.
C．The floating barriers can make the plastic bags come together.
D．The collected plastic bags can be recycled.
45．The author writes the passage to tell us ________.
A．to clean up the ocean B．to pollute the ocean
C．to protect the fish in the ocean D．to make our city a better place
We should not use more water than we actually need. If we do, we will not have enough water in the future. 46 It is not a difficult question to answer. If we remove more fresh water than nature replaces, we have taken too much.
Many cities run campaigns (运动) to get people to stop wasting water. They show their ways they can cut back on water use. 47 What’s more，they carry out programs that offer money to reduce water use. For example, they give people shower heads and toilets that use less water. 48 .
Another threat (威胁) to our water supply is pollution. When our sources of fresh water get polluted, we can no longer use this water. This also endangers (危及) the animals that depend on the water.
49 We can save lots of water by not letting taps (水龙头) run while we brush our teeth or by turning off taps right after washing hands. By collecting cold water when we’re taking warm showers, we can also save water. 50 In this way, we can make full use of water.
根据短文内容，从下列选项中选出能填入文中空白处的最佳选项。选项中有一项为多余选项。
A．However, just how much is too much
B．There are several things we can do to save water.
C．Finally, they make laws to control the use of water.
D．We don’t have to let the cold water run until it gets warm.
E．They also increase water bills for people who use too much.
F．We should ask the public to solve their problems.
四、短文填空

However, Maria doesn’t like this city although it’s easy for her to find a good job. The environment isn’t good here. The air 53 (pollute). The litter 54 (throw) everywhere. And at midnight, she 55 (wake) up by loud noises from time to time because there are many big factories around their house.
Maria often thinks of her life in the countryside. One day Maria 56 (see) her neighbor, Mrs. Garcia, carrying a gardening tool and a bag of soil. Maria wondered how Mrs. Garcia could garden in the city. “My mom used to 57 (grow) vegetables. Now we don’t have a yard, so she can’t do it,” said Maria.

Let’s try our best to protect the environment
Dear friends,
I’m a student of Grade 9. My name is Li Hua. As we know, we have only one Earth. But in recent years, many disasters happened on the Earth and unusual weather appeared very often. All these bad things were caused by the terrible environment, but the terrible environment was caused by humans. As students, what should we do
First, in order to protect our environment, we can give talks on how important the environment is. Second, we should save water and energy in our daily life. Third, in order to reduce air pollution, it’s better to go to school by bus, by bike or on foot. Fourth, we should divide the garbage into four kinds before putting it into the dustbins, and we should learn how to sort it. And we can reuse bags instead of plastic bags. Last but not least, no business, no killing. We all should know that wild animals are part of the environment, so we shouldn’t eat them. It’s time for us to protect wild animals.
If we all keep doing these things, I believe the environment will be better and better. Let’s try our best!
