Here is a page from a magazine called Future. Read the following information about things that may happen in ten years.

    Cars will run on solar power (太阳能) and will be much cleaner. They will be much safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself.
    New cities will have to be built in the sea. Some cities on water will have two levels (层). People will live on the upper level; the lower level will be used for traffic, shops and factories.
    Biotechnology (生物技术) will make food better and healthier. Plants without insects or illnesses (病虫害) will be developed. The taste of fruit and vegetables will be better and food will be kept longer.
    Many new ways to cure (治愈) illnesses will be found. People will use products of genetic engineering (基因产品) to cure more illnesses. However, some new illnesses will appear.

   Going to the zoo is very popular. Every year over 134 million visitors go to zoos to enjoy watching and learning about the animals. Zoos are the only places that most people will ever meet an elephant, a tiger or other animals that are in danger. {#blank#}1{#/blank#}. They help us to enjoy different kinds of animals as well as make us think more about nature(自然).

   Zoos are also important to animals. In order to make more space(空间), food, and other things for ourselves, we leave less and less room for animals. {#blank#}2{#/blank#}. If there were no zoos, more animals in the world would have gone extinct(濒临灭绝). {#blank#}3{#/blank#}. Some people think that animals should not be kept by people for any reason(原因). If they become extinct, then that's the way it should be. {#blank#}4{#/blank#}. We should do everything we can to protect them(保护它们).
{#blank#}5{#/blank#} What's the best title of this passage?

    Air is a colorless, tasteless and invisible（看不见的）gas that is around us. An "empty" drinking glass and an "empty" room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.

    Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth（布）into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.

    A about 6.0-magnitude(震级) earthquake(地震) hit Yi'bin, Sichuan at 22:55 on June 17th, 2019,and it killed at least 12 people and injured(受伤的) more than 220.

    Many people in Chongqing felt it. Most of them rushed out to the safe places such as the square, the playground, the street .But some didn't.

    What can we do when an earthquake happens? In fact, there's little we can do to stop natural disasters(自然灾害) such as earthquakes happening. But, some methods can reduce(减少) the harm they cause.

    Drop down onto your hands and knees. This way can protect you from falling.

    Cover your head under a strong table or desk. You can also stay along a wall, and cover your head with your arms and hands.

    Hold on to(守住，抓牢) your shelter(遮蔽物) until the shaking stops. Be prepared to move with your shelter if the shaking continues.

Schools can normally take the earthquake drills(演练) to help student stay alive.

    Tigers are the largest wild cats in the world. They usually go out to hunt for food when it is dark. And they hunt alone most of time. When a tiger sees an animal, it moves quickly and then jumps on the animal to kill it. Sometimes it can take the tiger several days to finish eating its food. When the tiger is full, it will cover the dead animal with leaves. Later, when the tiger is hungry again, it comes back to eat some more.

    Tigers are different from others in the cat family. They like water and often jump into rivers to swim. Some tigers live in very cold places-in North Korea, Russia and China. Other tigers live in warmer places-in India and parts of Southeast Asia.

    But now all tigers are in danger. Some people kill tigers to use their skins for clothes, and their bodies for medicine. There is also less land for tigers to live on.
