第一篇
A recent study,published in last week's Journal of American Medical Association,offers a picture of how risky it is to get a lift from a teenage driver. Indeed,a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone,by contrast,the risk of death for drivers between 30 and 59 decreases with. each additional passenger.
The author also found that the death rates for teenage drivers increased dramatically after 10 pm,and especially after midnight.With passengers in the car,the driver was even more likely to die in a late-night accident.
Robert Foss,a scientist at the University of North Carolina Highway safety Research Center, says the higher death rates for teenage drivers,have less to do with"really stupid behavior" than with just a lack of driving experience."The basic issue,"he says,"is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is."
Both he and the author of the study believe that the way to mitigate（使······缓解）the problem is to have states institute so-called graduated licensing systems,in which getting a license is a multistage process.A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult,followed by a period of driving with passenger restrictions,before graduating to full driving privileges.
Graduate licensing systems have reduced teenage driver crashes,according to recent studies. About half of the states now have some sort of graduated licensing system in place,but only 10 of those states have restrictions on passengers. California is the strictest,with a novice（新手）driver prohibited from carrying any passenger under 20(without the presence of an adult over 25)for the first six months.
According to Paragraph 3,which of the following statements is true?
A:Teenagers should spend more time learning to drive.
B:Driving is a skill too complicated for teenagers to learn.
C:Restriction should be imposed on teenagers applying to take driving lessons.
D:The licensing authorities are partly responsible for teenagers' driving accidents.

The World's Best-Selling Medicine
Since ancient times,people all over the world have used willow to stop pain. The willow tree contains salicylic acid（水杨酸）.This stops pain, but there is one problem. Salicylic acid also hurts the stomach. In 1853,a French scientist made a mixture from willow that did not hurt the stomach.
However,his mixture was difficult to make,and he did not try to produce or sell it.
In 1897,in Germany,Felix Hoffmann also made a mixture with salicylic acid. He tried it himself first and then gave it to his father because his father was old and in a lot of pain.
His father's pain went away,and the mixture did not hurt his stomach.
Hoffmann worked for Bayer,a German company. He showed his new drug to his manager,who tested the drug and found that it worked well.Bayer decided to make the drug.
They called it aspirin and put the Bayer name on every pill.
Aspirin was an immediate success. Almost everyone has pain of some kind,so aspirin answered a true need. Aspirin was cheap,easy to take,and effective. It also lowered fevers.
Aspirin was a wonder drug.
At first,Bayer sold the drug through doctors,who then sold it to their patients. In 1915,the company started to sell aspirin in drugstores.In the United States,Bayer had a patent（专利权）on the drug. Other companies could make similar products and sell them in other countries,but only bayer could make and sell aspirin in the United States.In time,Bayer could no longer own the name aspirin in the United States. Other companies could make it there,too.However,Bayer aspirin was the most well known,and for many years,it was the market leader.
By the 1950s,new painkillers were on the market. Aspirin was no longer the only way to treat pain and reduce fever. Bayer and other companies looked for other drugs to make.However,in the l970s they got a surprise. Doctors noticed that patients who were taking aspirin had fewer heart attacks than other people. A British researcher named John Vane found the reason aspirin helped to prevent heart attacks.In 1982,he won the Nobel prize for his research. Doctors started to tell some of their patients to take aspirin every day to prevent heart attacks.It has made life better for the many people who take it. It has also made a lot of mon-ey for companies like Bayer that produce and sell it!
Why was Felix Hoffmann looking for a painkiller?
A: His company told him to do that.
B: His father was in pain.
C: He wanted to make a lot of money.
D: He suffered from headache.

Common-cold Sense
You can't beat it,but you don't have to join it.Maybe it got the name"common cold"because it's more common in winter.The fact is,though,being cold doesn'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.
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't had the opportunity to become immune to many cold viruses.
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.
Colds are usually spread by direct contact,not sneezing or coughing.From another person'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.
Hygiene is your best defense.Wash your hands frequently,preferably with a disinfectant soap,especially when children in your household have colds.
But even careful hygiene won't ward off every cold.So,what works when a coughing,sneezing, runny nose strikes?
The old prescription of two aspirins,lots of water,and bed rest is a good place to start.But you'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.
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

Ants Have Big Impact on Environment as“Ecosystem Engineers”
Research by the University of Exeter has revealed that ants have a big impact on their local environment as a result of their activity as“ecosystem engineers”and predators. The study,published in the Journal of Animal Ecology,found that ants have two distinct effects on their local environment.
Firstly,through moving of soil by nest building activity and by collecting food they af-fect the level of nutrients in the soil. This can indirectly impact the local populations of many animal groups,from decomposers to species much higher up the food chain.
Secondly,they prey on a wide range of other animals,including larger prey which can be attacked by vast numbers of ant workers.
Dirk Sanders,an author of the study from the university's Centre for Ecology and Con-servation,said:“Ants are very effective predators which thrive in huge numbers. They're al-so very territorial and very aggressive,defending their resources and territory against other predators. All of this means they have a strong influence on their surrounding area.”
“In this research,we studied for the first time how big this impact is and the subtleties of it. What we found is that despite being predators,their presence can also lead to an increase in density and diversity of other animal groups. They genuinely play a key role in the local environment,having a big influence on the grassland food web,”Sanders said.
The study,carried out in Germany,studied the impact of the presence of different combinations and densities of black garden ants and common red ants,both species which can be found across Europe,including in the UK.It found that a low density of ants in an area increased the diversity and density of other animals in the local area,particularly the density of herbivores and decomposers. At higher densities ants had no or the opposite effect,showing that predation is counteracting the positive influence.
Dr Frank van Veen,another author on the study,said:“What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels,but as the number of ants increases,their predatory impacts have the bigger effect一thereby counteracting the positive influence via ecosystem engineering.”
Ants are important components of ecosystems not only because they constitute a great part of the animal biomass but also because they act as ecosystem engineers. Ant biodiversity is incredibly high and these organisms are highly responsive to human impact,which obviously reduces its richness. However,it is not clear how such disturbance damages the maintenance of ant services to the ecosystem. Ants are important in below ground processes through the alteration of the physical and chemical environment and through their effects on plants,microorganisms,and other soil organisms.
As predators,ants______.
A:prey on small as well as large animals
B: collect nutritious food from the soil
C: collect food as decomposers
D: prey on species much higher up the food chain
