              Four common bad habits combined—smoking, drinking too much, inactivity and poor diet—can age you by 12 years, sobering new research suggests.
The findings are from a study that tracked nearly 5,000 British adults for 20 years, and they highlight yet another reason to adopt a healthier lifestyle.
Overall, 300 people studied had all four unhealthy behaviors. Among them, 90 died during the study, or 30 percent. Among the 400 healthiest people with none of the four habits, 8 percent of them died.
The risky behaviors were: smoking tobacco; downing more than three alcoholic drinks per day for men and more than two daily for women; getting less than two hours of physical activity per week; and eating fruits and vegetables fewer than three times daily.
These habits combined substantially increased the risk of death and made people who engaged in them seem 12 years older than people in the healthiest group, said lead researcher Elisabeth Kvaavik of the University of Oslo.
The healthiest group included never-smokers and those who had quit; teetotalers, women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times daily.
"You don't need to be extreme" to be in the healthy category, Kvaavik said. "These behaviors add up, so together it's quite good. It should be possible for most people to manage to do it."
The US government generally recommends at least 4 cups of fruits or vegetables daily for adults, depending on age and activity level, and about 2 hours of exercise weekly.
小题1:What problem may you have, if you smoke often and eat few fruits and vegetables?
A.You would have difficulty in walking.B.You would feel tired, lack of energy.
C.You may look older than you really are.D.You may face the risk of death of cancer.
小题2:How many of the 400 healthiest people with none of the four habits died?
A.32.B.24.C.56.D.120.
小题3:What does this text mainly talk about?
A.Suggestions to smokers.B.The results of four bad life habits.
C.The findings of a new research.D.The recommends from the US government.

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , the number of such reasons is small. Pruning involves the cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.
First, pruning may be done to make sure that trees have desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches, which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air.
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合). Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce that risk of death as far as possible. It is important to make the area, which has been pruned, smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose. Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly .
小题1:.Why should pruning be done?
A.To make the tree grow taller.B.To improve the shape of the tree.
C.to get rid of the small ranches .D.To make the small branches thicker.
小题2:.Trees become unhealthy if the gardener__________.
A.giving a tree a special shape and a definite height
B.removing small side branches and making a tree look less thick
C.allowing too many branches to grow in the middle
D.having a tree surrounded by many other trees
小题3:.Why is a special material painted on the tree?
A.To help a wound to dry.B.to cover a rough surface.
C.To make a wound smooth.D.To prevent disease entering a wound.
小题4:.A good gardener prunes a tree _________ .
A.several times throughout the year B.as quickly as possible
C.occasionally when necessaryD.regularly every winter
小题5:.What was the author’s purpose when writing this passage?
A.To discuss different methods of pruning.
B.To introduce some common knowledge of pruning.
C.To explain how trees develop disease.
D.To give practical instruction for pruning a tree.

Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Eco-passages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages?  The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway.  This showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders(火蜥蜴)and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around.  You might see an animal overpass!
小题1: The writer uses the example of “ocelots” to show that __________.
A.wild animals have become more dangerous
B.the driving condition has improved greatly
C.an increasing number of animals are killed in road accidents
D.the measure for protecting wildlife fails to work
小题2:From the story, we know an eco-passage is __________.
A.an underground path for cars
B.a fence built for the safety of the area
C.a bridge for animals to get over a river
D.a path for animals to cross the road
小题3: When the writer says that “animals seem to be catching on” (Para. 6), he means __________.
A.animals begin to realize the dangers on the road
B.animals are crossing the road in groups
C.animals are increasing in number
D.animals begin to learn to use eco-passages
小题4: The writer asks visitors and drivers to look around when traveling because __________.
A.wild animals may attack carsB.they may see wild animals on eco-passages
C.they may see wild animals in the parkD.wild animals may jam the road
小题5: The best title for the passage is __________.
A.Special bridges help animals cross the road
B.Endangered animals increase because of roadkill
C.Animals fail to cross the road
D.Take steps to protect animals in danger

Situated in the South West of England, between Exeter and Plymouth, Torquay is one of the most popular holiday resorts in Britain. It provides a variety of entertainment, sports of every kind and cultural facilities, all set in a position of outstanding natural beauty. Visitors can choose between luxury hotels by the sea, with private suites(套房),swimming pools and saunas, and comfortable but less expensive guest houses. There are camping sites, too, and hundreds of houses displaying“B & B”signs.
As well as a number of small quiet bays, which are ideal for beach barbecues away from the crowds, Torquay has large sandy beaches where you can buy refreshments(饮料)and hire deck chairs, boats and even beach huts. There are large areas of grassland overlooking the sea, and miles of winding cliff paths for walkers who just want to enjoy the scenery and what is often said to be the healthiest air in the country. For the sportsmen and women there are opportunities not only for golf, tennis, squash and bowls, but also for water-skiing, hang-gliding and deep-sea fishing.
After a day in the open air, there’s lots to do in the evenings, too. There are plenty of discos, the occasional opera or ballet, and summer variety shows in the seafront theatres. For the children, there is a beautiful model village with a complicated railway layout which is remarkably realistic-especially when the lights are all on at night.
Of course, there’s no need to spend your whole holidays in Torquay. Only a short drive away is Dartmoor National Park, where you can walk for miles through dramatic, unspoiled countryside, or picnic by beautiful rivers and streams.

All sorts of items become litter(垃圾) but two of the most common and most dangerous are cigarette butts(烟头) and plastic bags. Litter is a big problem for our environment but it is a problem that individuals can easily do something about. Not littering at all or cleaning up litter, such as  cigarette butts and plastic bags, greatly improves the quality of our environment.
Although cigarette butts, are small, they are bad for the environment. Over 1,600 billion cigarette are smoked each year in China and large quantities of the butts are thrown away. Worldwide, about 4. 5 trillion butts are littered every year. Apart from the fact that butts spoil the beauty of the environment, they contain some very toxic chemicals. These find their way into the water supply where they decrease the quality of the water and endanger plants and animals that live there. So, if people have to smoke, they shouldn't throw away the butts but put them in the rubbish bin instead.
Plastic bags are another common form of litter that is a danger to the environment. There areseveral reasons for this. They are made from oil and gas, which are non—renewable resources. If they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous number of these become litter. This is a huge problem because they last from 20 to 1,000 years in the environment. They float easily in the air and water and travel long distances. They find their way to rivers, parks, beaches and oceans. Plastic bags kill up to one million seabirds, 100, 000 sea mammals and countless fish each year worldwide. It is up to people not to let plastic bags become litter. It would be better if they used fewer and recycled them.
Cleaning up your cigarette butts and plastic bags would improve the environment. And we would know that we were doing something to look after our planet. However, I believe the best solution would be not to smoke or use plastic bags at all.

   How men first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters. These letters could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken, or written in letters, we call words.
The power of words, then, lies in their associations---the things they bring up before our

minds. Words become filled with meaning for us by experience, and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar(粗俗的).

小题1:Which is TRUE about the origin of language?
A.Men, as well as animals, in vented certain sounds to express thoughts.
B.The origin of language is a complicated question.
C.Words did not haven written form, at first.
D.Words were invented to represent meanings.
小题2:The power of words lies in          
A.the fact that it can associate the things in the world with the ideas in our minds.
B.the fact that once word is connected with another
C.the fact that it can associate one person with another

A.the more we read and learn, the larger our vocabulary will be
B.the longer we live, the number of words that mean something to us increases
C.words can be used to represent various meanings

Another food which is closely associated with Americans is apple pie.Apple pie is often served hot with a spoon of ice cream or a slice of cheese at the end of the biggest meal of the day—dinner, and it is a favorite dessert throughout the nation, if a person is typical of Americans, we can say, "He is as American as apple pie."
It is true that the apple and apple pie do not originate in America, but the expression "as American as apple pie" is not the product of a pure imagination.As early as 1625, the English colonists, having brought orchards (果园) on this new land and in most of the colonial times, the apple was a main material of both plain and fancy cooking.The first Massachusetts governor, William Endicott, was one of many keen apple planters who helped to lay the foundations for today' s apple-growing industry in America.
A major attraction of the apple for the colonists was that it could be made into cider (苹果酒). Like most Europeans, English colonists held a strong suspicion (怀疑) of drinking water, and since grapegrowing was hindered by plant peats, cider became an alternative to wine.Cheap and easy to produce, it was the American drink of first choice well into the nineteenth century. Whether it was dried, raw or cooked, the apple also found its way into numerous colonial dishes, including apple sauces, pudding, stuffings and many desserts.Therefore, the conclusion to be drawn here is obvious.The apple pie became known as American, not because it was invented on this land (since it was proved that Europeans had been eating apple pies for centuries), but because, thanks to the huge orchards in the states of Washington and New York, America became the world's largest apple-producing nation.
小题1:If a person is said to be as American as apple pie, it means that _______.
A.he always prefers apple pie as a dessertB.his favourite pie is apple pie
C.he behaves and thinks in the American way D.he is good at making American apple pie
小题2:The apple can be used to make into all of the following except _______.
A.wineB.saucesC.puddingD.cider
小题3:The underlined word hindered in Paragraph 3 means.________.
A.promotedB.preventedC.improvedD.enlarged
小题4:It can be concluded from the passage that_______.
A.the apple pie was first served in America
B.the English colonists developed a taste for the apple only after they, arrived at the New World
C.the expression "as American as apple pie" is a pure imagination
D.the apple pie is traditionally associated with Americans due to their large apple production
