It seems that the Englishman just cannot live without sports of some kind. A famous French humourist once said that this is because the English insist on behaving like children all their lives. Wherever you go in this country you will see both children and grown-ups knocking a ball about with a stick or something, as if in Britain men shall always remain boys and women girls! Still, it can never be bad to get exercise, can it?
Taking all amateur（业余）and professional sports in Britain into consideration, there can be no doubt that football is at the top of the list. It is called soccer in the United States. The game originated in Britain and was played in the Middle Ages or even earlier, though as an organized game, or “association football”, it dates only from the beginning of the 19th century.
The next is rugby, which is called “football” in the United States. It is a kind of football played by two teams of fifteen players rather than eleven. The rugby, in which an oval-shaped ball is used can be handled as well as kicked. It is a pretty rough game.
In summer, cricket is the most popular sport. In fact, it has sometimes been called the English national game. Most foreigners find the game rather slow or even boring, but it enjoys great popularity among the British.
Tennis rates high on the list, too. It was introduced into England from France in the 15th century, but it was from England that it spread to practically every country in the world.
Table-tennis or “ping-pong” surely is not played on a great scale as it is in China or in Japan. Basketball and volleyball were introduced into Britain during the late 19th century from America and are gaining popularity. Horse-back riding, swimming, rowing and golf all attract a lot of people.
小题1:The main purpose of paragraph one is to tell us that the English_______.

A．are all sports lovers	B．behave like children
C．like to kick a ball around	D．can remain young all their lives

小题2:According to the passage, which of the following is NOT true about football and rugby?

A．They differ in the shape of the ball

B．They are played by different numbers of players

C．They both can be handled

D．They both can be kicked

小题3:From the second and the third paragraph, we know that_____.

A．Americans love football most of all

B．British people love rugby most of all

C．Americans and British people may call the same thing differently

D．football originated in Britain in the 18th century

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US．
When 40 per cent of Hawaii's US$14 million-a-year papaya （木瓜）industry was destroyed by a virus five years ago, work began on creating genetically engineered（转基因的）trees．
Researchers successfully introduced seeds that were designed to resist the virus．Since then, more and more people have been testing genetically engineered trees．Some researchers put special bacteria into trees to help them grow faster and produce better wood．Others are trying to create trees that can clean polluted soil．Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper．
The Pentagon （五角大楼） even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack．So far, the poplar, eucalyptus （杨树与桉树）, apple and coffee trees are among those being engineered．All this can be done today because we have a better understanding of tree genomes （基因组）．
However, some people fear that the genetically engineered trees will cause dangerous results．They are worried that the new trees will breed with natural species and change the balance of the forest environment．
“It could be destructive,” said Jim Diamond, an environmentalist. “Trees are what is left of our natural environment and home to many endangered species.”
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers．They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled．
63．Which kind of tree is not the ones that scientists are planting in the US?
A．Trees that worms can't hurt．
B．Genetically engineered trees．
C．Trees that can resist wind better．
D．Trees that can protect themselves at a chemical attack．
64．What caused the American scientists to work on special trees?
A．Tree genomes are mapped out so scientists know how to improve trees．
B．Great numbers of trees have been lost due to attacks by viruses．
C．Researchers successfully introduced seeds designed to resist the virus．
D．They think science could give nature a fighting chance against both natural and man-made dangers．
65．Which of the following was probably the first kind of trees being engineered?
A．Papaya． B．Pine． C．Apple． D．Poplar．
66．Why did critics think engineered trees dangerous? Because ________．
A．these trees can destroy the balance of nature
B．everything except trees has been genetically engineered
C．trees are home to many endangered species
D．these trees may affect normal trees

Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.
Some birds like eating locusts. but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you'll find the main use of colouring is protecting themselves. Bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.
Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn't strong at all.

Finally, this week’s comedy “Tomorrow’s Another Day” at the Cambridge MGM cinema, is another one in the long line of successes from director Peter Hamin.
This one has an unusual story line. Just imagine this; one day Mickey Style , a TV reporter, goes off to make a program about an exciting film festival in Canada. On his first morning there he wakes up, the sun is shining, the birds are singing , and life just couldn’t be better. He works through the day , goes to bed; wakes up the next morning… to find it’s the same day! The same sun, the same birds singing in the same tree, the same people saying and doing exactly the same things, day after day, He is caught in a place where time has simply stood still, where there will be no tomorrow.
This could be very serious, but it’s not. It’s an extremely funny film, which made everyone, including your reviewer (评论家) , laugh out loud. It has the silliest ending , and the audience loved it! Sabetha Tayior is great as the generous bank manager, yes, really, although Hollywood probably won’t give her any prizes. So if you want to forget your troubles, this is the film for you.
1.What is the writer trying to do in the text? _________

YOU CAN HELP!
Everyone was born with his own built-in burglar(窃贼) alarm. It’s called the sense of sight and sound．Unfortunately, many of us go around with the alarm switched off.
We don’t see the stranger wandering outside the house next door.
We don’t notice the sounds from the flat upstairs.
(Weren’t they supposed to be on holiday?)
The police can only do so much to prevent crime. There never can be enough of them to guard every home in every town. So they need your help in fighting with the burglars，the vandals（恣意破坏者）, and the car thieves.
Not, of course, by setting out to have a go every time you see something suspicious. It’ll always be the job of the police to arrest criminals.
But by acting as a line of communication between them and your community, for instance, you probably know far more about your immediate neighborhoods than the police ever could.
A stranger in someone’s garden would probably be far more obvious to you than it would to even the local police, if, of course, you were on the look-out.
That’s the whole idea behind the Neighborhood Watch schemes, springing up around the country to create a spirit of watchfulness within a community, anything suspicious being reported to the police.
It’s early days yet, but results so far are very encouraging. The crime figures are already dropping in many of the areas running the scheme. And all due to people like you.
61. The underlined word “them” refers to “______”.
A. criminals          B. the police   C. neighbors   D. strangers
62. The advertisement points out that many people______.
A. are not ready to help the police
B. are not as watchful as they could be
C. don’t look after their gardens well
D. don’t tell their neighbors about their holidays
63. One of the ways we could help prevent crime is to______.
A. turn on the alarm system in our home
B. try to stop criminals from escaping
C. look out for people behaving suspiciously
D. inform the police if we hear noises upstairs
64. The purpose of the advertisement is to __________in their neighborhood.
A. ask people to join the police force
B. advise people how to protect their homes
C. warn people about the increasing risk of crime
D. encourage people to be on watch for possible crime

For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing . At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) （一氧化碳）.
In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .
Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .
The oxygen in your blood passes into your tissues（组织）. But here again C

O makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude（高度）of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .
1．The gas amount in cigarette smoke is______________.
A．640 times higher than the gas safe levels in factories
B．640 times lower than the gas safe levels in factories
C．640 times as much as that in factories
D．as dangerous as that in factories
2．If you smoke , ______________ .
A．your blood carries more oxygen than is normal
B．your blood carries much more CO than is normal
C．you can have five to ten times of blood than usual
D．your blood will be poisonous
3．Those who smoke______________.
A．all live at sea level
B．don’t live at an altitude of two miles
C．breathe as much oxygen as non-smokers
D．only get the same amount of oxygen at the sea level as non-smokers at an altitude of nearly 2 miles
4．Smokers are______________.
A．easily hurt B．easily excited C．easily tired D．healthy
