The health of millions could be at risk because medicinal plants are being used up.These plants are used to make traditional medicine，including drugs to fight cancer.“The loss of medicinal plants is a quiet disaster，”says Sara Oldfield，secretary general of the NGO Botanic Gardens Conservation International.

Most people worldwide (including 80 percent of all Africans)rely on herbal medicines(草药)which are got mostly from wild plants.But some 15,000 of the 50,000 medicinal species are under threat of dying out，according to a report from the international conversation group Plantlife.Shortages have been reported in China，India，Kenya，Nepal，Tanzania and Uganda.

Overharvesting does the most harm，though pollution and competition from invasive(侵略性的)species are both responsible.“Businessmen generally harvest medicinal plants，not caring about sustain ability，”the Plantlife report says.“Damage is serious partly because they have no idea of it，but it is mainly because such collection is unorganized.” Medicinal trees at risk include the Himalayan yew and the African cherry，which are used to treat some cancers.

The solution，says the report's author，Alan Hamilton，is to encourage local people to protect these plants.Ten projects studied by Plantlife in India，Pakistan，China，Nepal，Uganda and Kenya showed this method can succeed.In Uganda the project has kept a sustainable supply of lowcost cancer treatments，and in China a public run medicinal plant project has been created for the first time.

“Improving health，earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants，”says Hamilton.“You have to pay attention to what people are interested in.” Ghillean Prance，the former director of the Royal Botanic Gardens at Kew in London，agrees that medicinal plants are in need of protection.

“Not nearly enough is being done，”he told New Scientist.“We are destroying the very plants that are of most use to us.”

The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. “Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it, but it is mainly because such collection is unorganized.” Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found.

A team from the School of Dentistry' s Violence Research Group studied drinking habits in

children aged | 1-16 in England. They found not only a link between drink and violence but also

that children who drank were more likely to be hit, even if they weren' t violent themselves.

The researchers are now calling for measures to prevent alcohol misuse to reduce injury

risk. Current policy focuses on reducing aggression but this research shows that there should be

equal effort to reduce victimization(受害).

More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 1 l-year-olds were drinking

monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age

of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed

22.6% of 16-year-olds were getting drunk more than 21 times a year.

The study, which has just been published in the Journal of Adolescence, found a strong

link between frequency of drinking and frequency of hitting other people.

However, children who reported drinking monthly were also three times more likely to be

hit. Adolescents(青少年) who drank but didn't get into fights were more likely to be hit than

those who did fight.

Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related

violence work had focused on the offenders rather than the victims. His team is calling for more pre-vention work from parents and teachers in the first two years of secondary school by taking advantage of the "teachable moment", that is, immediately after a student has missed school because of drunkenness.

Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of vio-lence because of reduced physical co-ordinatlon ( 配合), poor decision-making in threatening situa-tions and isolation while out late at night.

He said,"This new study seems to be the first to show a direct link between alcohol misuses and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury. "

58. The underlined word "aggression" in the third paragraph probably means_____

A. violence         B. sad feelings     C. bad manners          D. drunkenness

59. Drinkers may be more at risk of violence because of all the following EXCEPT __

A. reduced the physical co-ordination

B. isolation while out late at night

C. a higher frequency of hitting other people

D. poor decision-making in threatening situations

60. Which of the following statements is NOT true according to Professor Shepherd' s research?

A. The frequency of children getting drunk increases with age.

B. His previous alcohol-related violence work had focused on the offendersl

C. Some children missed school because of drunkenness.

D. This new study shows a direct link between alcohol misuse and victimization.

Teenagers who check social media for several hours a day are at the risk ofdeveloping ADHD (多动症), a study has concluded.

The research team, from the University of Southern California, tracked 2,600teenagers aged 15 and 16. They asked them how many times they checked theirphones and other digital devices for various reasons, and then monitored them for symptoms of ADHD. After two years, those who had checked their phones the mostoften were twice as likely as those who checked the least often to show signs ofADHD.

Writing in the JAMA medical journal, the scientists said, “Modern mediadevices immediately inform users when new text messages, social media postings, or videogame play invitations arrive. Exposure to such information may drawattention away from important tasks. Frequent distraction could interrupt thedevelopment of constant attention and organization skills.”

They believe constant access to instant entertainment also has an impact. Researcher Professor Adam Leventhal said all previous research had focused on the link between ADHD and televisions. “What’s new is that previous studies on thistopic were done many years ago, when social media, mobile phones, tablets andmobile apps didn’t exist. We can say with confidence that teens who are exposedto higher levels of digital media are significantly more likely to develop ADHDsymptoms in the future,” he said.

Leventhal believes the findings help fill a gap in understanding how newmobile media devices and seemingly limitless content pose a mental health risk forchildren. And the findings serve as a warning.

British scientists welcomed the findings. But Professor Andy Przybylski of theOxford Internet Institute said, “The study relies on survey responses provided bythe students in question. It is not clear if teachers or parents would rate the childrensimilarly or if the self-reported measure of digital screen use is related with eitheractual behavior or higher quality survey items.”

1.How did the researchers conduct the study?

A. By monitoring 2,600 teenagers with ADHD.

B. By tracking the participants for two years.

C. By analyzing data from previous researches online.

D. By controlling different teens’ time spent on social media.

2.What does Leventhal think of the exposure to higher levels of digital media?

A. It will cause diverse ADHD symptoms.

B. It will create higher ADHD risks.

C. It will weaken teenagers’ confidence.

D. It will have a major influence on organization skills.

3.What does Professor Andy Przybylski think of the study?

A. It provides a better understanding of the media.

B. It should have focused on parents’ responses.

C. Its findings are not reliable enough.

D. It’s a breakthrough in this field.

4.What can be a suitable title for the text?

A. The use of digital media is on the rise

B. Teens are increasingly exposed to ADHD

C. Heavy use of social media may increase ADHD risks

D. Teens’ exposure to modern media calls more attention

Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes, experts warn. Leading health researchers say they are “very concerned” by the growing number of youngsters trying the devices.

E­cigarettes have been marketed as a healthier alternative to smoking conventional cigarettes. But previous research shows e­cigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system.

Worryingly, researchers at Liverpool University discovered 16% of teenagers who have used e­cigarettes had never previously smoked. The experts also found e­cigarettes were “strongly related” to drinking among teenagers. Study author Prof. Mark Bellis said, “Our research suggests that we should be very concerned about teenagers accessing e­cigarettes. While debate on e­cigarettes has focused largely on whether or not they act as a gateway to tobacco cigarette use, e­cigarettes themselves contain a highly addictive drug that may have more serious and longer lasting impacts on children because their brains are still developing.”

Researchers surveyed 16,000 students aged 14 to 17 in the North West of England and asked them about their alcohol and tobacco use. They found that one in five answered yes to the question: “Have you ever bought or tried electronic cigarettes?” More males than females said they had.

Of the teenagers that had accessed e­cigarettes, 16% had never smoked, 23% had tried smoking, 12% only smoked when drinking, and 14% were ex­smokers. The research also found teenagers who drank alcohol were significantly more likely to have accessed e­cigarettes than non­drinkers.

Among those who had never smoked, it was found that those who regularly have excessive(过多的)drinking were four times more likely to access e­cigarettes than those who never drink. In all of those that drink, regardless of smoking status, e­cigarette access was associated with excessive drinking and involvement with violence after drinking. The researchers said their findings suggest that teenagers who use e­cigarettes are most susceptible to other forms of substance use and risk­taking behaviors.

1.How have e­cigarettes been promoted in the market?

A. As a healthier substitute for traditional cigarettes.

B. As a device meeting the mental needs of smokers.

C. As a product preventing smokers from using tobacco products.

D. As a new device promoted among youngsters.

2.What do we learn from the survey made in the North West of England?

A. E-cigarettes are now widely available and heavily promoted.

B. E­cigarette access is linked to excessive drinking and violence after it.

C. Teenagers are very knowledgeable about alcohol and tobacco use.

D. The number of adult cigarette smokers is dropping at present.

3.Which of the following can replace the underlined words “susceptible to” in the last paragraph?

A. greatly interested in

B. commonly accustomed to

C. deeply disappointed at

D. easily influenced by

4.What's the main idea of the passage?

A. Experts are concerned about excessive drinking in teenagers.

B. The harm of the e­cigarettes is greater than that of alcohol.

C. Teenagers are in danger of risking their health on e­cigarettes.

D. Researchers are aware of smoke­related health harm.
