根据以下材料，回答题

Ward off Travel Bugs

（1） As the holiday season approaches， so does the prospect of jet lag， an upset stomach or sunburn.

With care and some help fi"om natural sources， however， it is quite possible to avoid these problems.

（2） You can start to prepare a couple of weeks before you leave. Food poisoning will make any holiday miserable， but by taking some medicine such as lactobacillus and bifidobacteria， you can reduce the likelihood of poisoning caused by food or water tainted （感染，污染） with unfamiliar bacteria.

（3） By improving the bacteria balance in your digestive tract， you crowd out the pathogenic （病原的）bacteria and stop them gaining a foothold. The beneficial bacteria also produce gentle but effective natural antibiotics （抗生素） in yourgut.

（4） In many holiday locations you need to remember the basics: drink bottled water， avoid undercooked meat and ensure that food hygiene （卫生） is adequate. If you get food poisoning，drink plenty of water to stay hydrated（保持水分）and see a doctor. However， if you detect diarrhea（腹泻） early enough， you might like to try taking about 10 or 15 pancreatic digestive enzymes， which can digest the multiplying bacteria before they take over.

（5） Taking a teaspoon of silicol gel can also help. This lines the stomach and upper intestinal area and binds with bacteria and viruses， allowing them to be safely passed out of the gut. When you pack，include grapefit-it-seed extract， which is an excellent all-round anti-bacterial， anti- parasitic，anti-viral （抗毒的） and anti-fungal （杀菌的） agent.

（6） Your flight can also be made more pleasant. Peppermint oil and ginger capsules （胶囊） ward off motion sickness， but a more delicious option is to eat crystallized ginger. If you tend to get ear-ache on take-off and landing， you can use special ear plugs with filler that slows down the rate of change in air pressure.

（7） The greatest concern is "economy class syndrome"， the popular name for deep-vein thrombosis （血栓症） ， which can lead to blood clots traveling from the legs to the lungs， heart or brain. To reduce this， you need a couple of hours to stay hydrated， and avoid alcohol.

（8） You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoid quercetin. Vitamin C and quercetin also help to reduce prickly heat.

（9） Finally， if any adverse symptoms persist while overseas， you should see a doctor.

阅读材料，回答题。

How does Organisms Ward off Invaders

The livelihood of each species in the vast and intricate assemblage of living things depends on the existence of other organisms．This interdependence is sometimes subtle，some times obvious．Perhaps the most straightforward dependence of one species on another occurs with parasites，organisms that live on or in other living things and derive nutrients directly from them．The parasitic way of life is widespread．A multitude of microorganisms(including viruses and bacteria，and an army of invertebrates or creatures lacking a spinal column(including crustaceans，insects，and many different types of worms)make their livings directly at the expense of other creatures．In the face of this onslaught，living things have evolved a variety of defense mechanisms for protecting their bodies from invasion by other organisms．

Certain fungi and even some kinds of bacteria create substances known as antibiotics into their external environment．These substances are capable of killing or inhibiting the growth of various kinds of bacteria that also occupy the area，thereby eliminating or reducing the competition for nutrients．The same principle is used in defense against invaders in other groups of organisms．For example，when attacked by disease--causing fungi or bacteria，many kinds of plants produce chemicals that help to ward off the invaders．

Members of the animal kingdom have developed a variety of defense mechanisms for dealing with parasites．Although these mechanisms vary considerably，all major groups of animals are capable of detecting and reacting to the presence of“foreign”cells．In fact，throughout the animal kingdom from sponges to certain types of wornls shellfish，and all vertebrates(creatures possessing spinal column)

there is evidence that transplants of cells or fragments of tissues into an animal are accepted only if they come from genetically compatible or closely related individuals．

The ability to distinguish between“self”and“non-self”，while present in all animals，is most efficient among vertebrates，which have developed an immune system as their defense mechanism．The immune system recognizes and takes action against foreign invaders and transplanted tissues that are treated as foreign cells．

What does the passage mainly discuss？ 查看材料

A.How parasites reproduce

B.How organisms react to invaders

C.How antibiotics work to cure disease

D.How the immune system of vertebrates developed

请根据短文的内容，回答题。

Common-cold Sense

You can&39;t beat it, but you don&39;t have to join it. Maybe it got the name "common cold" because it&39;s more common in winter. The fact is, though, being cold doesn&39;t have anything to do with getting one. Colds are caused by the spread of rhinoviruses, and, at least so far, medical science is better at telling you how to avoid getting one than how to get rid of one.＜br＞

Children are the most common way cold viruses are spread to adults, because they have more colds than adults -- an average of about eight per year. Why do kids seem so much more easily to get colds than their parents？ Simple. They haven&39;t had the opportunity to become immune to many cold viruses.＜br＞

There are more than 150 different cold viruses, and you never have the same one twice. Being infected by one makes you immune to it -- but only it.＜br＞

Colds are usually spread by direct contact, not sneezing or coughing. From another person&39;s hand to your hand and then to your nose or eyes is the most common route. The highest concentration of cold viruses anywhere is found under the thumbnails of a boy, although the viruses can survive for hours on skin or other smooth surfaces.＜br＞

Hygiene is your best defense. Wash your hands frequently, preferably with a disinfectant soap,especially when children in your household have colds.＜br＞

But even careful hygiene won&39;t ward off every cold. So, what works when a coughing, sneezing, runny nose strikes？＜br＞

The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you&39;ll also find some of the folk remedies worth trying. Hot mixtures of sugar(or honey), lemon,and water have real benefits.

According to the essay， you may have a cold because__________. 查看材料

A.the weather is too cold

B.the spread of rhinoviruses gets people infected

C.another person"s coughing passes the cold to you

D.you wash your hands too often

根据以下材料，回答题Invisibility RingScientists can"t yet make an invisibility cloak like t

根据以下材料，回答题

Invisibility Ring

Scientists can"t yet make an invisibility cloak like the one that Harry Potter uses. But， for the first time， they"ve constructed a simple cloaking device that makes itself and something placed inside it invisible to microwaves.

When a person "sees" an object， his or her eye senses many different waves of visible light as they bounce off the object. The eye and brain then work together to organize the sensations and reconstruct the object"s original shape. So， to make an object invisible， scientists have to keep waves from bouncing off it. And they have to make sure the object casts no shadow. Otherwise， the absence of reflected light on one side would give the object away.

Invisibility isn"t possible yet with waves of light that the human eye can see. But it is now possible with microwaves. Like visible light， microwaves are a form. of radiant energy. They are part of the electromagnetic spectrum， which also includes radio waves， infrared light， ultravioletmys， X rays， and gamma rays. The wave lengths of microwaves are shorter than those of radio waves but longer than those of visible light.

The scientists" new "invisibility device" is the size of a drink coaster and shaped likearing. The ring is made of a special material with unusual ability. When microwaves strike thering， very few bounce off it. Instead， they pass through the ring， which bends the waves all the way around until they reach the opposite side. The waves then return to their original paths.

To a detector set up to receive microwaves on the other side of the ring， it looks as if the waves never changed their paths as if there were no object in the way! So， the ring is effectively invisible.

When the researchers put a small copper loop inside the ring， it， too， is nearly invisible.

However， the cloaking device and anything inside it do cast a pale shadow. And the device works only for microwaves， not for visible light or any kind of electromagnetic radiation. So， Harry Potter"s invisibility cloak doesn"t have any real competition yet.

Harry Potter is mentioned in the passage， because scientists __________. 查看材料

A.can now make an invisible cloak of the same kind as he uses

B.try to make an invisible cloak of the same kind as he uses

C.try to invent a device similar in idea to the invisible cloak he uses

D.know that it is possible to make an invisible cloak of the same kind

根据以下材料，回答题。

The Fridge

1 The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: "store in the refrigerator. "

2 In my fridgeless Fifties childhood， I was fed well and healthily. The milkman came daily， the grocer， the butcher， the baker， and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes. NOthing was wasted and we were never troubled by rotten food. Thirty years on， food deliverieshave ceased， fresh vegettbIes are almost unobtainable in the country.

3 The invention of the fridge contributed comparatively little to the art of food preservation. A vast variety of well-tried techniquesady already existed natural cooling， drying， smoking， salting，sugaring， bottling...

4 What refrigeration did promote was marketing marketing hardware and electricity， marketing soft drinks， marketing dead bodies of animals around the globe in search of a good price.

5 Consequently， most of the world"s fridges are to be found， not in the tropics where they might prove useful， but in the ，Tealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter， millions of fridges hum away continuously， and at vast expanse，busily maintaining an artificially-cooled space inside an artificially-heated house，-while outside，

nature provides the desired temperature free of charge.

6 The fridge"s effect upon the environment hasbeen evident， while its contribution to human happiness has been insignificant. If you don"t believe me， try it yourself. Invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers but at least you"ll get ride of that terrible hum.

A.The invention of the fridge.

B.The pollution caused by fridges.

C.The widespread need for fridges.

D.The days without the fridge.

E.The waste of energy caused by fridges.

根据以下材料，回答题

Mad Scientist Stereotype Outdated

Do people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed？ The Institute of Physics set out to find out whether the stereotype of a physic"boffin" （科学家） still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong. Most people picked a white male of around 60， wearing glasses and with a white beard.

While this stereotype may have been the image of all average physicist fifty years ago， the reality is now very different. Since 1960 the number of young women entering physics has doubled and the average age of a physicist is now 31.

The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting by blackboards full of equations （等式） or working with fizzing （嘶嘶响 ） test tubes. These stereotypes are really damaging to society. Very good school children are put off studying science because they don"t see people like themselves on television or in magazines doing science. They simply don"t relate to the media"s image of the mad scientist.

This is one reason why fewer young people are choosing to do science at university. If we want to encourage more young people to study science subjects， we need to change this image of the scientist and make science careers more attractive. But we must also develop children"s interest in science.

In an attempt to change this negative image， an increasing number of science festivals are being organized. Thousands of people from secondary schools are also encouraged to take part in the internationwide science competitions of which the most popular are the national science Olympiads. Winning national teams then get the opportunity to take part in the Intemational Science Olympiads which are held in a different county every year. These events are all interesting for the young people who take part but they only involve a small proportion of students who are already interested in science. It seems that there is a long way to go before science becomes attractive as subjects like computer studies or fashion and design.

Most people have similar ideas of what a physicist looks like. 查看材料

B.Wrong

根据以下材料，回答题American SocietyWhen foreigners are sometimes asked what seems most str

根据以下材料，回答题

American Society

When foreigners are sometimes asked what seems most strange about American society，somewhere on the top of the list will be the fact the average citizen is allowed to possess guns.

Although it is true that many people carry guns legally in the United States， it is also known that many who possess guns carry illegally. Others， who don"t have guns， feel that guns can be acquired quite easily. A recent survey indicated that many high school students， especially in the inner cities， can acquire gun with little difficulty.

Although most people would never want to own a gun， others have taken up hunting as a sport and enjoy hunting wild game in season. Hunting for deer and duck in fall and winter is very much a part of the American culture.

Also， some farmers in rural areas who raise cattle and sheep feel they need to protect their animals against wolves that attack their herds and flocks at night. To defend and support their rights to possess firearms the National Rifle Association （NRA） was founded in 1871. The main importance of this organization has been its efforts to prevent strict gun control legislation. The NRA has great political support in small towns and rural areas， especially in the West and the South，where hunting is especially popular. Those who favor the right to possess guns insist that the Constitution provides the right of people "to keep and bear arms". They believe that gun control laws will not solve the problem of crime and violence in America.

Recent events in America， however， have shown that the question of gun possession is now out of control and strong voices have called for immediate action to be taken. In seemingly peaceful schools students have gone into classrooms and opened fire upon their classmates.

America has been shocked by such incidents which seem to occur with greater frequency. The periodic deaths of innocent citizens and even foreign visitors from guns have forced legislators to pass laws to stop these senseless killings.

The day may not be far off when America will be transformed from a gun culture to one which controls their use and possession.

What is most unusual about American society？ 查看材料

A.Many Americans acquire guns illegally.

B.Ordinary people can possess guns legally.

C.The average citizen does not try to possess guns.

D.Many school children carry guns legally.
