live on the planet Mars. Our own planet, Earth, is becoming more and more crowed and polluted. Luckily,
we can start again and build a better world on Mars. Here is what life could be like.
First of all, transport should be much better. At present, our spaceships are too slow to carry large
numbers of people to Mars-it takes months. However, by 2100, spaceship can travel at half the speed of
light. It might take us two or three days to get to Mars!
Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can
be grown on Mars. These plants will produce the food and air that we need. However, can these plants
produce water for us? There is no answer now.
There is a problem for us to live on Mars. Mars pulls us much less than the Earth does. This will be
dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans
on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better than that on Earth in many ways, People will have more space. Living in a
large building with only 10 bedrooms is highly possible. Many people believe that robot will do most of our
work, so we have more time for our hobbies.
There will probably be no school on Mars. Every student will have a computer at home which is
connected to the internet. They can study, do their homework and take exams in online schools. Each student
will also have their own online teacher called "e-teacher".
However, in some ways, life on Mars may not be better than that on the earth today. Food will not be
the same-meals will probably be in the form of pills and will not be as delicious as they are today. Also,
space travel will make many people feel ill. The spaceship will travel fast but the journey to Mars will probably
be very uncomfortable.
B. on the moon
C. under the sea
D. in the sun
B. A few months
C. A few days
D. A few years
B. will study mainly in a classroom
C. will meet each other face to face every day
D. needn"t study at all
B. there will be more space and less work to do
C. there will be much delicious food
D. all students don"t need to do any homework
B. We need to develop a special plant which can produce water.
C. On Mars, we can jump higher than on the earth.
D. Food will be much more tasty.

Beijing-Shanghai Railway was completed in 1968. The line runs 1,462 km between China"s two main
cities and passes through five provinces and the city of Tianjin.
Since opening, it has been one of the busiest routes in our country. The Beijing-Shanghai route is now
served by 10 trains a day, five of which are non-stop. The journey time is just under 12 hours.
Now trains are allowed to travel at 250 kph (kilometers per hour) and the journey time is only 10 hours.
With the sixth railway speedup, China has joined the ranks (行列) of countries with high-speed rail services. Trains are able to run at speeds of 200 kph on some 6,003 km of track (轨道), and on some sections, the
highest speed can increase to 250 kph. The 6,003 km of track serves both high-speed passenger trains and
low-speed cargo (货物) trains.
Railway operators have to deal with the problem of the speed gap (差距) between the two kinds of trains
to make sure they both run safely.
B. No, it doesn"t.
C. It"s very far.
D. We don"t know.
B. Six.
C. Seven.
D. Eight.
B. twelve hours
C. one day
D. two days
B. Beijing-Shanghai Railway passes through six provinces.
C. All of the trains run without any stops on Beijing-Shanghai Railway.
D. Since opening, Beijing-Shanghai Railway has been one of the busiest routes in China.
B. a dictionary
C. a newspaper
D. an advertisement
when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat
formed (形成) a circle about six meters across. Around this circle were four smaller circles of flattened wheat.
Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These
circles were larger-nearly 15 meters across. That same year, another English farmer discovered three circles
of flattened wheat on his land-one large circle between two small circles. During the following years, farmers
in England found circles in their fields more and more often.
The circles are called "crop circles" because they usually appear in fields of wheat or corn. The wheat in
the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it.
Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear
only in the months from May to September. What causes the crop circles?
At first, people thought that some kids were making them as a joke, or that farmers were making them to
attract tourists.(In fact, in 1991, two men said they made the circles themselves, but many scientists don"t
believe them.) People tried to copy them: They tried to make circles exactly like the ones the farmers had
found. They couldn"t do it. They couldn"t enter a field of wheat without leaving tracks, and they couldn"t
flatten the wheat without breaking it.
Several times people reported seeing stranger objects near the fields where crop circles later appeared.
Many people believe that these crop circles are the messages sent by living things from outer space (外层空间) or the marks left by their spaceships.
Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990
some scientists spent three weeks in the part of England where many circles have appeared. They had all the
latest high-tech equipment (最新高科技设备). The equipment-worth 1.8 million dollars-got nothing. But one
night, as the scientists were watching a field, crop circles formed in the field behind them, which were quite
different from the others. The scientists had neither seen nor heard anything.
When Steven discovered the crop circles on his land in 1978, he said, "It was just like something that had
landed in the field from the air and gone back up again. I don"t know what to make of these things."
Crop circles have appeared in England, Japan, the United States and Russia. Experts from all over the
world have studied them, and they say what Steven said: They don"t know what to make of these things.
B. lying wheat
C. harvested wheat
D. growing wheat
B. that cannot be solved but found all around the world
C. that cannot be made clear or understood
D. that is discovered and copied by the farmers
countryside think so. For hundreds of years, they have observed animals. They think animals" behavior
(行为) can be connected to future weather conditions or events. For example, if swans fly into the wind,
a hurricane is coming. Or, if cows lie down, a rainstorm is coming. There are many traditional stories
connecting animals and natural events. Many people think that these stories are just folklore, traditional
stories and beliefs without scientific evidence (证据). Scientists, however, are beginning to take another
look at some of these ideas.
Kiyoshi Shimamura is a Japanese earthquake researcher. He noticed an increase in dog bites a short
time before earthquakes hit. Then, he did an investigation (调查) of twelve public health centers in Kobe,
Japan. These health centers treated people after the 1995 earthquake. He noticed some interesting
information about the month before the big earthquake. Treatment for animal bites had increased. In fact,
aggressive (冒犯的; 侵略的) behavior in dogs, such as biting and barking loudly, jumped (猛增) 60
percent!
People noticed other changes in animal behavior before the earthquake as well. For example, fish began
swimming together in large groups, only in the middle of the water and not near the edges. Also, birds flew
away from their nests for many days, leaving their eggs unprotected. The animal behavior suggests that
animals may be able to predict natural events better than people.
B. Many earthquakes of Japan
C. Effect (影响) of natural events on animals" actions
D. Folklore and other stories about animals
B. They stay together in large groups.
C. They leave their homes.
D. They hurt people.
B. Birds
C. Cows
D. All of the above
B. The number of patients with bites
C. The number of earthquakes a year
D. Places dogs go during earthquakes
ago?
The 1 wild dogs were trained by 2 in Europe about 10,000 years ago. These first "dogs" were not
like 3 we have now. They may have been small wolves. These dogs often came near humans to 4 some
food. Some of the young dogs were adopted (收养) by people and grew up with them.
Humans believed the 5 were a help to them in many ways. The dogs helped them to hunt (狩猎). They
could smell and hear danger 6 . people could. They helped keep people 7 on cold nights. So is was 8
to raise the dogs.
Now, there are many different kinds of dogs 9 they may look quite different from each other. Dog trainers
think there are more that 400 different kinds in the world. The number keeps increasing with new kinds.
Since those early days, humans and dogs have always been together. We should 10 them from now on
because they are really our friends.

| We have always been interested in the moon. 2000 years ago people already knew it moved around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky. When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on Earth. This was because they believed the moon had once been a planet that had been caught in the earth"s gravity (引力) millions of years earlier. In 1969 moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information. After years of study, most scientists now think that the moon was once part of Earth. They believe very early in its history, maybe 4 million years ago, something about the size of Mars hit Earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon. In the future, even though our ideas about the moon may change again, we will still be interested in it. | |||

| A. Why people are interested in the moon. B. How ideas about the moon have changed over time. C. Where the moon came from in the past. D. That people have finally learned the truth about the moon. | |||
| 2. Before 1969 most scientists thought the moon was _____. | |||
| A. part of the earth billions of years earlier B. older than the earth C. a planet caught by the earth"s gravity D. made of the same things as the earth | |||
| 3. From this passage we can learn that _____. | |||
| A. scientists in the past were not clever B. the earth was once part of the moon C. new information brings new ideas D. we now know everything about the moon |
