planet. The first man-made satellite went into the orbit in 1957. By 1968 there were over three hundred
satellites in the orbit. Some satellites send back weather pictures. Others send out radio waves. Some
satellites are what we call "junk". In 1963, the United States put millions of small pieces of wire into orbit.
They were used to carry radio waves. Many of these wires may still be there. Some space junk was not
put in the orbit. For example, one piece of space junk is a glove lost by an astronaut!
Space is very big. Does it matter if there is junk in the orbit? Many scientists think so. They say we
must pay much attention to how we use this new resource. They think anything man puts into space
should be made to come back to earth when its work is done. They say it"s dangerous to have space junk,
because it"s possible for spacecraft to collide with the junk.
B.1963
C.1968

money back! From the first day your pronunciation will be excellent. Just send…" and so on? Of course,
it never happens quite like that. The only language that is easy to learn is the mother tongue. And think
how much practice that gets! Before the Second World War people usually learned a foreign language in
order to read the literature (文学) of the country. Now speaking the foreign language is what most people
want. Every year many millions of people start learning one. How do they do it? Some people try at home,
with books and tapes; some use radio or television programmes; others go to evening classes. If they use
the language only two or three times a week, learning it will take a long time, like language learning at school.
A few people try to learn a language fast by studying for six or more hours a day. It is clearly easier to learn
the language in the country where it is spoken. However, most people cannot afford this, and for many it is
not necessary. They need the language in order to do their work better. For example, scientists and doctors
mainly need to be able to read books and reports in the foreign language. Whether the language is learned
quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the students work
for him.
B. half a year
C. six months
D. less than two month
August, it is very hot and wet in the southern part of the United States. People there have heart trouble
and other kinds of health problems during this month. In the northeast and the Middle West, it is very hot
at some times and very cold at other times. People in these states have more heart trouble after the weather
changes in February or March.
The weather can also influence intelligence. For example, in a 1983 report by scientists that IQ of a
group of students was very high when a very strong wind came, but after the strong wind, their IQ was
10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can
make it lower. Students in many schools of the United States often get worse on exams in the hot months
of the year (July and August).
Weather also has a strong influence on people"s feelings. Winter may be a bad time for thin people. They
usually feel cold during these months. They might feel unhappy during cold weather. But fat people may
have a hard time in hot summer. At about 18℃, people become stronger.
Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on
low pressure days. There is "good weather" for work and health. People feel best at a temperature of
about 18℃.
Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather"s problem.
B. Good weather
C. Warm weather
D. High intelligence
important choices by themselves. They need to think about questions like these: Should we go to college?
What kind of jobs do I want? However, other people also influence their choices. Who influences teenagers?
It depends on the kind of choice. When teenagers buy things,friends are the most important influence.
This is especially true for clothes and music. TV shows, advertisements and parents also influence teenagers.
In more serious things, parents are probably the most important influence. Some teenagers say it"s best to
regard both parents and friends as influences. James, a seventeen-year-old boy says he"s "just a crazy man",
he also says, "Parents are really important because they can tell you what"s right and wrong. " But teenagers
also feel they need to make choices-to make their own mistakes. As one teenager girl said, "If our parents
don"t let us make our own choices, maybe in the future we don"t know how to do it. " And they feel friends
can often be a big help, especially because friends sometimes know more about their situation than their
parents do.
Do you depend on parents or others when you decide what to do and how to do it? Whoever you depend
on, the correct choice is the most important. Your future is in your hand.
( )1. People from 13 to 19 can be called teenagers.
( )2. When teenagers buy clothes and music, friends are the most important influence.
( )3. TV shows and advertisements can"t influence teenagers.
( )4. In more serious things, friends are probably the most important influence.
( )5. Sometimes friends know more about teenagers" situation than their parents.
We also learn that it can be very terrible when there is a strong wind. What 3 things do we know about
it? The first thing to remember is that the sea is very big. 4 the map of the world. There is 5 sea
than land. The sea covers three-quarters of the 6 .
Some parts of the sea 7 very shallow (浅). But some places are very deep. There is one place near
Japan. It is nearly 11 kilometres deep. The 8 mountain in the world is about 9 kilometres high. If we put
that mountain into the sea at that place, there would be 9 kilometres of water above it!
The sea is salty. There is one sea called the Dead Sea. It is very salty. It is 10 salty that swimmers
cannot sink! Fish cannot live in the Dead Sea.
but your car may have two wings (翅膀). New Scientists Magazine says American Aviation Company is
going to test a flying car.
The Skycar looks like a red bat mobile (蝙蝠状的可移动物). It seats about four people and has a top
speed of over 600 km per hour. At that speed, a 200-km trip only takes about 20 minutes. It will be able to
take off and land up and down, like a helicopter (直升飞机). During its first test, the Skycar will rise to a
height of 2 meters, hover (盘旋) for one minute, and then land.
The Skycar is hand-built and cost about $1 million. The company thinks that one day the Skycar will
cost about $60,000.
