Today, many endangered animals live in zoos. There, scientists work to keep each species(物种) alive. How do they do that? One way is by taking cells(细胞) from animals. Then the cells are frozen(冷冻). They can be used in the future to help animals reproduce.

The San Diego Zoo has been freezing cells for 40 years. It's also called the Frozen Zoo. Now, the zoo is the biggest of its kind, with a large gene bank. It has cells from more than 1,000 species. One of the species is the northern white rhinoceros(犀牛).

There are only five northern white rhinoceros alive in the world now. They are unable to have their children. Some scientists there want to use the bank's frozen cells to produce another northern white rhinoceros. They want to do this before the species dies out. That could happen by 2025.

Can the zoo save the northern white rhinoceros? Other species have been saved successfully. So it's possible for the white rhinoceros too.

Saving the white rhinoceros would be expensive. So some people don't think using frozen cells is the best thing to do. Some wonder whether it's worth spending millions of dollars on the species that nearly dies out. Some say scientists should work on the reasons why animals become endangered in the first place.

（1）、What is the first passage mainly about?

A、Why scientists want to keep each species alive. B、Introducing one way of keeping each species alive. C、Introducing the situation of endangered animals. D、How to freeze cells from animals.

（2）、The underlined word "That" in the third paragraph refers to ______.

A、reproducing the northern white rhinoceros B、the northern white rhinoceros dying out C、the northern white rhinoceros having babies D、freezing cells from the northern white rhinoceros

（3）、Why do some people disagree on saving the white rhinoceros?

A、Because they don't know why animals become endangered. B、Because the animals are useless to people. C、Because it's dangerous to save them. D、Because saving them is too expensive.

（4）、From the passage we can learn that ______.

A、scientists succeeded in saving some endangered animals B、it's good for the endangered animals to live in zoos C、the San Diego Zoo is famous for its gene bank D、people have known the reasons why animals become endangered

Plant scientists consider them as fruit. Most other people think of them as vegetables. Whatever you call tomatoes, there are many different kinds of this popular and healthy food.
There are two groups of the plants. Small tomato plants grow to about one meter. They can be planted rather close together. Some short kinds do not require special care and are often gotten crop by machines. Large tomato plants can grow over two meters tall. They also produce larger fruits.
People who grow only a few plants can place wire cages around each one. The cage can be made of wire fence material. The cage helps the plant grow taller and produce a better crop.
Tomatoes often need extra calcium (Ca), or the fruits may be ruined. Add lime to the soil can solve this problem. Dry lands may also ruin the fruits. Tomatoes need water regularly. The soil should never dry out completely. Dried grass or leaves placed around the plant can help hold water in the soil and stop the growth of unwanted plants.
Tomatoes are native to South America. The tomato is a member of the potato family. The leaves of the plant are poisonous, like the leaves of its relatives. Before the 18th century, people grew tomatoes only as pretty plants. They called the bright red fruit a “love apple”, but would not eat it.

    Habit is any action that we have performed so often that it becomes something that we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to get rid of these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.
    First, look at why you do it. In other words, what's the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it? It may make you feel a little better for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get more time to spend on the Internet!
    Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn. When you think that way, you'll find that it's not wise to keep your bad habit! Now it is time to make a decision. What will you choose? I'm sure you will choose to do what you think is more important.

Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.

    Now satellites(卫星)are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere(大气), because this is where the weather forms(形成). They send these pictures to the weather station. So meteorologists(气象专家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
    Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare(比较)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
    So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead(提前).

    “High tech” and “state of the art” are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention or system that uses the newest ideas or discoveries of science and engineering.
    What is high tech? A computer is high tech. So is a communications satellite. A modern manufacturing (制造业的) system is surely high tech.
High tech became a popular expression in the United States during the early 1980's. Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave ovens (微波炉), etc. “State of the art” is something that is as modern as possible. It is a product that is based on the very latest ways and technology. Something that is “state of the art” is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modern electronic design and parts. It is the best that one can buy.
    “State of the art” is not a new expression. Engineers have used it for years, to describe the best and most modern way of doing something.
Millions of Americans began to use the expression in the late 1970's. The reason was the computer revolution（革命）. Every computer company claimed (声称) that its computers were “state of the art”.
    Computer technology changes so fast that a state of the art computer today might be old tomorrow. The expression “state of the art” has become as common and popular as computers themselves. Now all kinds of products are said to be “state of the art”.

What will the world of the future be like? There are plenty of people who are happy to give their opinion of what we will be doing in 2050. Here are two predictions about the world of tomorrow.

When we dream about the future, many like to think of owning a personal flying car. The advantages are obvious. This technology would allow total freedom of movement. We could fly at 480 km per hour, avoiding traffic lights and busy roads. However, some people believe there will be problems with traffic control. If the cars become popular, there is likely to be air traffic jam. Another big problem is mechanical failure. What will happen if the cars stop working? These are problems we must expect if flying cars become a reality.

Three-dimensional printing is another new technology with exciting possibilities. 3D printers are used to build an object with liquid plastic.

They build the object layer by layer until it is complete. Car companies already use 3D printers to make life-size models of car parts, and medical companies use the technology to make man-made body parts. As we move into the future, 3D printing will revolutionize the way we shop, the way we manufacture and the way we treat sick people. The disadvantage is that such equipment will be extremely expensive.

So in the future, we might be able to fly to work or print out new shoes. Although there are some problems to solve before this will be possible, we can certainly dream of a world where technology makes life easier and safer for millions of people.
