Long ago, people put food in ice houses in winter. Today, fridges are used in almost every home. Inside a fridge, there is a special liquid. When it moves through the pipes, it becomes cold and takes heat away from the food. The food is kept at a low temperature, so bacteria grow slowly. That is why food stays fresh for a longer time. However, a fridge only slows down bacteria. We should not keep food for too long. Scientists say that a fridge is one of the most useful inventions for the kitchen. 第19小题：Where did people put food in winter long ago? 第20小题：Why does food stay fresh in a fridge? 第21小题：What do scientists say about the fridge? 短文2： Plastic was invented about one hundred years ago. At first, people wanted a cheap material to replace ivory. An inventor made the first plastic from plant materials. It could be shaped into any form when heated. Soon, plastic was produced in large numbers. Toys, bags, bottles and pens were made of it. Plastic is light, strong and cheap, so it changed our life completely. However, plastic does not break down easily. It stays in the ground for hundreds of years. Today, scientists are trying to invent new plastics that are kind to the earth. 第22小题：Why was plastic invented at first? 第23小题：What was the first plastic made from? 第24小题：What advantage does plastic have according to the passage? 第25小题：What problem does plastic cause? 第四节 听短文填空 Boys and girls, attention, please.

He noticed that many parents had to throw away broken toys at home. He had an idea: why not fix toys for people? He put a small sign in front of his house: Toy Repair Corner. At first, only a few neighbors came. Later, more and more people brought broken toys to him. Zihan does not do the work for money only. He charges very little, and he teaches children how to fix simple things themselves. This year, he opened a free toy-repair class at the community centre. More than thirty kids come every Saturday. Zihan says his dream is to study engineering at university. He wants to design machines that can help old people. From a small toy corner to a big dream, the boy is on his way. 59.

C The Long Snake That Digs Tunnels Digging a long tunnel through a mountain is hard and slow work for humans. But today, a special machine does most of the job. The tunnel boring machine, or TBM, is like a long snake under the ground. At its front, there are many sharp cutting discs. As the machine moves forward, the discs grind through rock and earth. The waste material is carried out by a conveyor belt. At the same time, workers inside the machine put concrete rings on the walls, so the tunnel will not fall down. One TBM can dig as much as thirty metres a day. It works day and night, and it does not disturb the people on the ground above. Different TBMs are built for different ground: some for soft earth, others for hard rock. China now has some of the largest TBMs in the world. They have helped build tunnels under rivers, mountains and even the sea. Thanks to these powerful machines, our journeys are becoming shorter and easier. 63. What is a TBM mainly used for? A. Building houses. B. Digging tunnels. C. Making cars. D. Cutting trees. 64. What are the cutting discs at the front of a TBM used for? A. Lighting the way. B. Carrying workers. C. Grinding through rock and earth. D. Painting walls. 65. Why do workers put concrete rings on the tunnel walls? A. To make the tunnel not fall down. B. To make the tunnel beautiful. C. To keep animals out. D. To save money. 66. What can we learn about TBMs from the passage? A. TBMs are very small. B. TBMs are made in Japan. C. TBMs dig only one metre a day. D. TBMs work day and night and do not disturb people above. D Plants: Little Air Cleaners at Home Indoor air pollution is a problem we do not always notice. Paint, furniture and even cleaning products may release harmful gases into the air. But scientists have found a natural helper: green plants. A study was done in a sealed room. Scientists put three common indoor plants in the room, which had a small amount of harmful gas in the air. After twenty-four hours, they tested the air again. They found that the amount of harmful gas had dropped by nearly fifty percent. The plants took in the gases through their leaves, and the bacteria in the soil also helped break them down. Another finding was also interesting: plants cleaned the air better when their soil was wet. However, if the air was too dry, the plants worked more slowly. The study suggests that keeping a few green plants at home is a simple and cheap way to improve indoor air. Next time you buy a plant, remember: it is not only beautiful, but also working as a little air cleaner for you. 67. What may release harmful gases indoors according to the passage? A. Windows. B. The sun. C. Paint, furniture and cleaning products. D. Fresh air. 68. What happened to the air after twenty-four hours in the study? A. The plants died. B. Harmful gas dropped by nearly fifty percent. C. The air became worse. D. Nothing changed. 69. When do plants clean the air better according to the study? A. When their soil is wet. B. When the air is dry. C. At night. D. In winter. 70. What does the study advise people to do? A. Buy more furniture. B. Open windows less. C. Use more cleaning products. D. Keep a few green plants at home. 第二节 阅读表达（共5小题，每小题2分） 阅读下面短文，并根据短文内容回答问题。 Paper is so common that we seldom think about where it comes from and how many trees are cut for it. But do you know that old paper can be turned into new paper again? Recycling paper is not magic. It starts when waste paper is collected and sorted. Then the paper is put into big tanks with water. It is torn into very small fibres and mixed well, like making porridge. This soft mixture is called pulp. Next, the pulp is spread thinly on a moving screen. The water drains away, and the fibres stick together. Finally, the thin sheet is pressed and dried, and it becomes new paper again. Recycling one ton of waste paper can save about seventeen trees. It also uses less water and energy than making paper from wood. That is why many schools now have waste-paper recycling boxes. Next time you finish a piece of paper, do not throw it away at once. Put it in the recycling box, and let it get a new life in this world. 71. What happens first when paper is recycled? ________________________________________________ 72.
