muscles when you pick up a heavy object. However, there is a correct way to lift things from the floor. If you
pick up big or heavy objects correctly, you probably will not hurt your back.
To lift something from the floor correctly, first bend your knees and squat (蹲) down. Keep your back
straight. Don"t bend over from your waist; keep your back and hips (髋) and waist (腰) in a line. If you bend
over, the muscles in your lower back can become hurt very easily. If you keep your back and hips straight, the
muscles are stronger, because they have much more support. The other muscles can then help the lower back
muscles.
As you squat down, try to get as close to the object as possible. For example, if you are going to pick up a
heavy box, squat down directly in front of it, maybe you will have to spread your knees and legs. Put one knee
on each side of the box. Remember at all times to keep your back straight.
Put your hands under the object that is in front of you, between your knees.
To lift the object, you should stand up slowly. Use your muscles in order to stand up. In other words, lift
with your legs, not with your back.
B. back
C. knees
D. hands
B. to bend your knees and squat down
C. to put one knee on each side of it
D. to straighten your back at all times
B. Putting one knee in front of the thing.
C. Standing up slowly.
D. Putting your hands under the thing between your knees.
a. Keep your back straight.
b. Bend your knees.
c. Spread your knees and legs.
d. Squat down.
e. Stand up slowly.
B. b, a, c, e, d
C. b, d, a, c, e
D. b, a, d, c, e

Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west
from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射)
stream. The jet stream is a very high altitude wind which always blows from the west to the east across the
Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are
moving with the wind than in the opposite direction.
What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away?
What happened would depend on how strongly the things were attached (附着) to the Earth. The Earth is
moving at quite a speed, moving at over a thousand miles per hours. If you turn something around your head
on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line.
"Switching off" gravity would be like letting go of the string. Things not attached to the Earth would fly off in
a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling.
Most things outside would fly off into space.
B. Planes go slower when they are moving with the wind
C. It takes more time to fly from NY to London than from London to NY
D. The yet stream always blows from the east to the west across the Atlantic.
B. move quickly
C. come out
D. grow quickly
B. trees and buildings would not easily fly off
C. something around your head would not fly away
D. everything outside buildings would fly off into space
and the general principles apply to any language. Naturally, you will not read every book at the same speed.
You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook-
but you can raise your average reading speed over the whole range of materials you wish to cover so that the
percentage (百分比) grained will be the same whatever kind of reading you are concerned with.
The reading passages which follow are all of an average level of difficulty for your stage of instruction.
They are all about five hundred words long. They are about topics of general interest which do not require a
great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks
and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English,
with understanding at four hundred words per minute, you might skim (浏览) through a newspaper at perhaps
650~700, while with a difficult textbook you might drop to two hundred or two hundred and fifty.
Perhaps you would like to know what reading speeds are common among native English-speaking university
students and how those speeds can be improved. Tests in Minnesota, U.S.A., for example, have shown that
students without special training can read English of average difficulty, for example, Tolstoy"s War and Peace
in translation, at speeds of between 240 and 250 words per minute with about seventy percent comprehension.
Students in Minnesota claim that after twelve half-hour lessons, once a week, the reading speed can be
increased, with no loss of comprehension, to around five hundred words per minute.
B. The introduction to a book on fast reading.
C. The introduction to an English textbook.
D. A local newspaper for young people.
in the University of Minnesota?
B. You can increase your reading speed by four times.
C. You can increase your reading speed by three times.
D. No real increase in reading speed can be achieved.
B. about two hundred and forty-five words per minute
C. about five hundred words per minute
D. about three hundred words per minute
_____.
B. improve your understanding of an economics textbook
C. choose the suitable material to read
D. only in your reading of a physics textbook
as people call it, is drawing more and more attention now. Sometimes it"s a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost
do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two
killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied,
not only these two diseases can be cured completely, bringing happiness and more living days to the patients,
but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the
economy as well. In addition, human life span (寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the
English imperial (皇帝的) family being a good example, have hereditary (遗传的) diseases. This means their
children will for sure have the family disease, which is a great trouble for these families. In the past, doctors
could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. Scientists just
need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture (生产) human beings in large
quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict
that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for
most couples in the world can have babies in very normal way. Of course, the governments must take care to
control gene technology.
B. The two murderers who killed the cloned baby.
C. The two diseases of cancer and heart disease.
D. Hereditary diseases and cancer.
B. Gene technology can be used to clone human babies.
C. How gene technology can be used to treat hereditary diseases.
D. Gene technology can solve all the problems of the English imperial family.
B. Using gene technology, scientists find the wrong gene and correct it.
C. Using gene technology, human babies can be cloned.
D. Doctors can cure cancer and heart disease with the help of gene technology.
B. Telling people the advantages and disadvantages of gene technology.
C. Telling the readers that gene technology will not benefit people.
D. Explaining that gene technology will also do harm to the humanity.
Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist. At least,
this is what psychologists tell us, and they should know, because they have been seriously studying the
meaning of colour preference, as well as the effect that colours have on human beings. 2_____. If you happen
to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
3_____. A yellow room makes most people feel more cheerful and more relaxed than a dark green one;
and a red dress brings warmth and cheer to the saddest winter day. 4_____. A black bridge over the Thames
River, near London, used to be the scene of more suicides (自***) than any other bridge in the area-until it was
repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even
more if the bridge had been done in pink or baby blue.
5_____. It is an established fact that factory workers work better, harder, and have fewer accidents when
their machines are painted orange rather than black or grey.
B. They tell us, among other facts, that we do not choose our favourite colour as grow up - we are born with
our preference.
C. The rooms are painted in different colours as you like.
D. If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.
E. Light and bright colours make people not only happier but more active.
F. Life is like a picture or a poem, full of different colours.
G. Colours do influence our moods-there is no doubt about it
Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result
of where and how you live? These are very old questions and the answers to them are still not clear.
We know, however, that just being born with a good mind is not enough. In some ways, the mind is like
a leg or an arm muscle. It needs exercise. Mental (done with the mind) exercise is particularly important for
young children. Many child psychologists (心理学家) think that parents should play with their children more
often and give them problems to think about. The children are then more likely to grow up bright and intelligent.
If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become
dull and unintelligent. Parents should also be careful with what they say to young children. According to some
psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely
to keep doing silly and foolish things. So it is probably better for parents to say very positive (helpful) things to
their children, such as "That was a very clever thing you did." or "You are such a smart child."
B. pretty and handsome; ordinary-looking
C. great and important; common
D. hopeful and helpful; careless
B. a strong person; a weak person
C. a highly intelligent person; a foolish or weak-minded person
D. a famous person; an ordinary person
B. often thinking about difficult problems
C. often helped by his parents and teachers
D. born with a good brain and putting it into active use
B. to be hard on their children
C. to leave their children alone with nothing to do
D. to give their children as much help as possible
B. The less you use your mind the duller you may become.
C. Intelligence is obviously the result of where and how you live.
D. What makes a person bright or stupid is still under discussion.
