Now satellites are helping to forecast（预报）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 stations. So meteorologists（气象学家）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 that 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 three or five days. Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.

1. Satellites travel _____________.

A. in space                               B. in the atmosphere

C. above the ground                   D. above space

2. Why do we use the weather satellites to take pictures of the atmosphere? Because __________.

A. the weather satellites can do it easily             B. clouds form there

C. the weather forms there                        D. the pictures can forecast the weather

3. Meteorologists forecast the weather __________.

A. when they have received satellite pictures

B. after they have compared new satellite pictures with earlier ones

C. before they received satellite pictures

D. during they study satellite pictures

4. Maybe we’ll soon be able to forecast the weather for ________.

A. one day                              B. two days

C. five days                            D. seven days or even longer

5. The main（主要的）idea of this passage is that satellites are now used in _________.

A. taking pictures of the atmosphere             B. receiving pictures of the atmosphere

C. doing other work in many ways              D. weather forecasting

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.

We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.

Global Positioning System (GPS) (全球定位系统)

It’s a system that uses radio signals from satellites to show exact (精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers.

Space Technology

Russian and American scientists have worked together for the International Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless (无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space.

Underwater Robot

Hercules is a kind of Underwater Robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago. The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the time.
(   )1. ______ can tell you where the user is on the earth exactly.

A. Satellites                          B. Receivers

Snow fell on the mountain. It snowed and snowed. The snow did not melt（融化）. It became deep and heavy. The snow on the bottom pressed （挤压）together., it became ice.

The ice was very wide and thick. It began to move down the mountain. It was like a river of ice. It was a glacier（冰河）.

Sometimes the glacier moved only a few inches（英寸） each day. As it moved, it took rocks and dirt with it. It changed the land. In some places, it left hills. In some places, when the glacier melted, it made rivers and lakes.

A million years ago, there were many big glaciers. Glaciers covered many parts of the world. The glaciers changed the land.

Glaciers are still at work today. A glacier in the north of Canada is cutting a new path（路） down the side of a mountain. This glacier will change the land, too.

Long ago, people in Rome（罗马） talked to one another in Latin（拉丁文）. Pupils in school learned to read and write in Latin. Books are in Latin.

Some Romans（罗马人）went to other parts of the world. They took their language with them. Soon Latin was used in many countries. It became a world language.

People in other countries did not talk in Latin the same way. In each land, they changed the language a little. As time went by, they made more changes. At last they did not talk in Latin any more. New languages had come from the old one.

We have known for a long time that flowers of different plants open and close at different time of day. This is so familiar that there seems to be no need to ask the reason for it. Yet no one really understands why flowers open and close like this at particular times. The process (过程) is not as simple as we might think, as recent experiments have shown. In one study, flowers were kept in constant (连续的) darkness. We might expect that the flowers, without any information about the time of day, did not open as they normally do. In fact, they continued to open at their usual time. This suggests that they have some mysterious (神秘的) way of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of “inner clock”.

This discovery (发现) may not seem to be very important. However, it was later found that not just plants but also animals —including man —have this “inner clock” which controls the working of their bodies and influences (影响) their activities. Men, then, are also influenced by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.

In the past, this did not matter very much because people lived in natural condition. In the modern world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very useful, then, to know more about the “inner clock”. Such ordinary things as flowers might help us understand more about ourselves.

1. A recent experiment showed that ________________.

  A. different flowers open and close at different times of day

  B. for their opening and closing, flowers do not need information from the outside world

  C. flowers are influenced by weak light even when they are in a dark room

  D. flowers can be used for telling the time

2. The “inner clock” _________________________.

   A. is an unimportant discovery           B. is only found in animals

   C. has not been understood by far         D. has an effect on human life

3. Further study of the “inner clock” will be useful because ________________.

   A. it might help us in some way

   B. we do not yet understand plants and animals well enough

   C. the number of spacemen and airplane pilots is fast increasing

   D. we should try to live more naturally than we do now

4. Kept in constant darkness, flowers ________________________.

   A. will not open or close as usual           B. will not open any longer

   C. will open as they do in natural conditions   D. will always remain in full blossom (开花)

5. ________________ have a mysterious power of knowing time without information from the outside world.

   A. Animals including man as well as plants      B. All living things except man

   C. Flowers are the only things in the world that   D. Neither animals nor plants
