It is home to many animals and plants, but it is facing many problems today.One of the biggest problems is plastic pollution. Every year, millions of tons of plastic end up in the oceans. This plastic pollution is harmful to sea animals and birds, because they often mistake plastic for food. As a result, many sea creatures (生物) get sick or die.Another problem is the rising sea level. Because the Earth is getting warmer, the ice is melting in the North and South Poles, causing the sea level to rise. This causes floods in the areas near the sea. What’s worse, lots of people living near the sea have to move. It is also harmful to sea life, as their home gets destroyed (遭破坏的).Overfishing is also a problem to the sea. People catch too many fish, faster than they can reproduce (繁殖). If we don’t stop, there will be fewer fish in the future. Overfishing does harm to not only the fish but also other animals that depend on them for food.To protect the sea, we need to do something. We can do this by using less plastic and recycling more. We can also learn about the sea and teach others why it is important. Together, we can take care of the sea and make sure it is safe for animals, plants, and people. We need to remember that the sea helps us, so we must also help the sea.( )33. How many problems is the sea facing according to the text?A. 2. B. 3. C. 4. D. 5.( )34. Why is the sea level rising?A. Because there is more rain falling into the sea.B. Because people pour too much water into the sea.C. Because the Earth is getting warmer and the ice is melting.D. Because the sea animals are making the water rise.( )35. What might happen if overfishing doesn’t stop?A. There will be more kinds of fish in the future.B. Other animals that depend on fish for food will have enough to eat.C. The number of fish will become smaller and it will affect (影响) other animals too.D. People will stop catching fish.( )36. What does the last paragraph mainly talk about?A. The problems the sea is facing. B. The reasons for the rising sea level.C. The importance of sea animals. D. How to protect the sea.DThe Sahara Desert in North Africa is the largest hot desert in the world. It is about 1,800km from the north to the south and about 4,800km from the east to the west. Temperatures can reach 58℃ in the daytime and can fall to -6℃ at night. More than 8,000 years ago, the Sahara was a rich land where farmers grew food and plants grew well. As the rainfall in the area gradually went down every year, it became a huge desert. Most areas of this desert have less than 13cm of rain every year.Gary Smith and a few of his brave friends decided to hike across the Sahara. Supporters in cars, who carried food and water for the group, stayed with them together.One day, Smith walked alone and then he couldn’t find the rest of the group. Even worse, he could not find out which direction to go. Then a sandstorm covered the area. When the storm was over, Smith was even more worried. In the heat that he couldn’t stand, he quickly finished his water. He had to spend that night out in the open, and he almost felt he couldn’t survive (生存).The next day, he walked on. After the second night, he started to worry about dying. He realized that his friends might not find him in time. It was late on the third day that Smith lost his consciousness and fell over.When Smith awoke, he was in the car with his friends. He had been found by a group of Bedouins who were traveling in a truck. In such a large desert with the weather conditions, this made it possible for him to survive. Then the Bedouins returned to his group of friends. Smith was so lucky.( )37. How did the Sahara turn into a desert according to the text?A. People cut down more and more plants. B. There was less and less rain.C. The temperature was higher and higher. D. The animals ate up all the plants.( )38. Which of the following is the right order according to the passage?a. Gary Smith got lost in the desert. b. Gary Smith fell over on the desert.c. There was a sandstorm in the area. d. Gary Smith was saved by some travelers.A. a-c-b-d B. a-d-c-b C. a-d-b-c D. c-a-b-d( )39. What does the underlined word “this” in Paragraph 4 refer to?A. Traveling in a truck. B. Being in this kind of weather.C. Being found by Bedouins. D. Hiking across the Sahara.( )40. What’s the writer’s purpose of writing the text?A. To show that the Sahara is in great danger.B.

This year’s theme is “Planet vs. Plastics” (全球战塑). So, I decided to try something different: a whole day without using any plastic. It sounded exciting, but it was quite hard.My morning started with a homemade breakfast in a glass bowl. But later when I tried to order juice as usual, I had to give up because of those plastic cups. I faced a bigger problem at the supermarket. Almost everything was wrapped (包装) in plastic—from fruits and vegetables to meat. It made me realize that plastic is everywhere, making it hard to carry on with my no-plastic plan.Plastic is widely used in our daily life. It can be made into all kinds of things such as bags, bottles and toys. It’s tough (牢固的) and it’s really light. So we depend heavily on it.But there’s one thing: Using too much plastic can be harmful to the environment. Humans use about one million plastic bottles every minute, and more than 5 trillion plastic bags are used each year according to a United Nations report. The world produces 200 million tons of plastic waste each year, but only less than 10 percent has been recycled. Most of them end up in the lakes, rivers and oceans, hurting animals and nature.To make a difference, China stopped the production, sale and use of plastic shopping bags with a thickness of less than 0.025mm in 2008. From 2010 to 2020, China recycled 170 million tons of waste plastic. These have helped reduce plastic waste.Let’s join hands and make a clean and beautiful world.66.

Today I am very glad to be here to give a speech on saving the Earth.Our Earth was healthy and beautiful in the past. However, it is facing a lot of serious problems now. The number of wild animals is getting smaller and smaller. What’s worse, there are more and more natural disasters than before, such as floods and sandstorms. Both people and animals are in great danger now.Why does this happen? Firstly, people cut down too many forests. As a result, a lot of wild animals have nowhere to live or nothing to eat. Besides, more and more smoke and waste cause a great deal of pollution and climate change. Therefore, natural disasters happen more often than before.In order to improve the situation, both the government and people should take action right now. The government should make laws to prevent people from cutting down trees. At the same time, everybody should realize the importance of protecting the environment and do what they can to help it.That’s all. Thank you very much!A. Soon, Basu found a way to do this.B. They also taught the students how to protect them.C. I’m happy to make the earth a better place.D. Her friends didn’t want to know about forestry at all.E. When she was a little girl, she always liked to watch animals.F. The government is still trying to get more money to build schools.G. At that time, she came to learn about a serious problem in her country.ProblemsAnimals in dangerMore natural disastersCausesCut down forests...AdviceThe government. . ....
