A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect. Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality. In addition, smokers tend to be unhappier than non-smokers. However, after taking account of previous ill health, smoking, and other lifestyle and socio-economic factors, the investigators found that unhappiness itself was no longer associated with increased mortality.
The lead author, Dr Bette Liu, now at the University of New South Wales, Australia said: "Illness makes you unhappy, but unhappiness itself doesn't make you ill. We found no direct effect of unhappiness or stress on mortality, even in a ten-year study of a million women."
As in other studies, unhappiness was associated with deprivation, smoking, lack of exercise, and not living with a partner. The strongest associations, however, were that the women who were already in poor health tended to say that they were unhappy, stressed, not in control, and not relaxed.
The main analyses included 700 000 women, average age 59 years, and over the next 10 years these women were followed by electronic record linkage for mortality, during which time 30 000 of the women died.
After allowing for any differences already present in health and lifestyle, the overall death rate among those who were unhappy was the same as the death rate among those who were generally happy. The study is so large that it rules out unhappiness being a direct cause of any material increase in overall mortality in women.
This was true for overall mortality, for cancer mortality, and for heart disease mortality, and it was true for stress as well as for unhappiness.
1. The word “mortality” in the passage means .
A. richness B. relaxation
C. death D. morality
2. According to the passage, which of the following statements is true?
A. Unhappiness will definitely make a person ill.
B. Unhappiness doesn’t necessarily make you ill.
C. Unhappiness is not associated with lack of exercise.
D. The death rate among those unhappy people is greater.
3.It’s wrongly believed that ________.
A. unhappiness itself is not associated with increased mortality
B. there is no direct link between unhappiness and mortality
C. ill health directly causes unhappiness and stress
D. ill health directly results from unhappiness and stress
4.The writer’s attitude towards the result of the study is __________.

The analysis in The Lancet looks at obesity (肥胖) trend in over 200 countries. In the UK, one in every 10 young people aged 5 to 19, is obese. Obese children are likely to become obese –adults, posting them at risk of serious health problems, say experts. Researchers believe wide availability of cheap, lattening food is one of the main drivers.
Although child obesity rates appear to be stabilizing in many high-income European countries, including the UK, they are accelerating at an alarming rate in many other parts of the world. The largest increase in the number of obese children has been in East Asia. China and India have seen rates “balloon” in recent years. Polynesia and Micronesia have the highest rate of all — around half of the young population in these countries is overweight or obese.
The researchers say that if current world trends continue, “obese” will soon be more common than “underweight”. “We have not become more weak-willed, lazy or greedy. The reality is that the world around us is changing.”
Dr Fiona Bull from the World Health Organization suggested tough measures to prevent “calorie-rich, nutrient-poor food” and entourage more physical activity. “But so far, just over 20 countries around the world have introduced a tax on sugary drinks,” she said.
Dr Alison Tedstone, chief nutritionist (营养学家) at Public Health England, said, “Our sugar reduction programme and the government’s sugar tax are world-leading, but this is just the beginning of a long journey to meet the challenge of a generation. The evidence is clear that just telling people what to do won’t work. While education and information are important, deeper actions are needed to help us lower calorie consumption and achieve healthier diets.”
1.What mainly contributes to child obesity according to the researchers?
A. Children don’t take enough physical exercise.
B. Children are driven to consume cheap diets.
C. Children become more weak-willed and greedy.
D. Children can reach cheap and fattening food more easily.
2.How can we describe child obesity rates in France?
A. Alarming. B. Steady.
C. Slow. D. Ballooning.
3.What may Dr Fiona Bull think of the sugar tax?
A. It is world-leading. B. It is not effective enough.
C. It needs to be promoted further. D. It should be made to be less tougher.
4.What can be inferred from the last paragraph?
A. England is the first to tax sugary drinks.
B. Solving the problem of child obesity is a hard nut.
C. Education plays a small role in controlling child obesity.
D. People should be told about the danger of being overweight.

The study, published today in the journal PLOS Biology shows that the average body size and number of sharks and other marine predators—vital to maintaining healthy ocean ecosystems—fell significantly near cities with more than 10,000 people and associated fishing boats.
The minimum distance from people and fishing which had no measurable effect was 1,250 kilometers. This is far further than previous studies have suggested and probably reflects the increased distances fishing boats can now travel. As a result, sharks were only observed at 12% of sites monitored.
Lead author Dr. Tom Letessier said, ''Human activity is now the biggest influence on sharks' distribution. Just 13% of the world's oceans can be considered 'wilderness' but sharks and other predators are much more common and significantly larger at distances greater than 1,250 kilometers from people. This suggests that large marine predators are generally unable to thrive near to people and is another clear example of the impact of human overuse on our seas. ''
To collect their data, the team analyzed videos taken at 1,041 sites across the Indian and Pacific Oceans, selected to test the biggest possible range of conditions and habitats. Sharks and other free-swimming predators were studied using cameras attached cannisters(炮筒)filled with bait. In total, the team recorded 23,200 animals representing 109 species. These included 841 individual sharks from 19 different species.
Dr. Letessier added, ''Our study also found that shallower water environment, of depths less than 500 meters, were vital for marine predator diversity. We therefore need to identify sites that are both shallow and remote and protect them. However, there are still numerous shallow hot spots near human markets that are not appropriately protected, and this must change. ''
1.According to the study, what happened to sharks and other marine predators?
A.They became less important for keeping healthy ocean ecosystems.
B.They only lived near cities with 10,000 people.
C.They loved swimming after fishing boats.
D.Their average body size and number decreased sharply.
2.Which of the following statements may Dr. Tom Letessier agree with?
A.Large marine predators can grow well near people.
B.People shouldn't disturb the sea and sea animals.
C.Sharks’ distribution was mainly affected by human activity.
D.Other ecological factors have no impact on sharks’ distribution.
3.What does the author intend to do in Paragraph 4?
A.Introduce a new topic for readers.
B.Introduce the study means used by the team.
C.Summarize the previous paragraphs.
D.Collect data about sharks and other predators.
4.What can we infer about the perfect environment for marine predator diversity?
A.It should be deeper than 500 meters.
B.It should be spots that are hot enough.
C.It should be shallower and away from humans.
D.It should be spots changed from human markets.

In a study published in the U. S. journal Science, researchers from the Chinese Academy of Agricultural Sciences(CAAS) and the University of Florida identified the chemical combinations and genetic recipe for better tomato flavor(味道).
“In recent years, consumers often complain that the modern tomato is less flavorful than it once was” said co-principal researcher Sanwen Huang. “Our results provide a practical road map for breeding tomato varieties with better flavor.”
For the study, a 170-person consumer group was created to evaluate 160 tomatoes representing 101 varieties, based on qualities such as “overall liking” and “flavor degree”. The results pointed to dozens of chemical compounds of interest, and further research using a statistical model discovered 33 flavor compounds connected with consumer liking, such as glucose(葡萄糖). The reason why modern tomatoes don’t taste good anymore is that a total of 13 of these flavor-associated compounds “were significantly reduced in modern varieties,” their paper wrote. Moreover, the researchers found that smaller fruit tended to have greater sugar content, suggesting that “selection for more sizable tomatoes has cost sweetness and flavor”.
Based on this knowledge, Huang and Professor Harry Klee of the University of Florida studied the whole genomes of 398 varieties of tomato, identifying about 250 positions of genes on a chromosome(染色体), which controlled tomato flavor.
“We’re just fixing what has been damaged over the last half century to push them back to where they were a century ago,” said Klee in a statement. “We can make the supermarket tomato taste noticeably better.” Klee said new tomato varieties with better flavor could be ready in three to four years. In addition, “the genes and pathways identified here in the tomato almost certainly point to pathways worth researching for improvement of flavor quality in other fruit crops,” they wrote.
1.According to the text, the study ________.
A. was carried out just through a survey
B. was conducted by Chinese researchers themselves
C. was completely focused on the genes of different tomatoes
D. was done with the background of declining flavor of tomatoes
2.The researchers have found that ________ in the study.
A. bigger tomatoes are much sweeter
B. some genetic positions affect the taste of tomatoes
C. some chemical compounds make tomatoes less tasty
D. a total of 13 flavor-associated compounds make tomatoes appealing in taste
3.What is the influence of the study according to the text?
A. The study lays the foundation for further researches to improve other fruit crops’ flavor.
B. The study makes it possible for us to have noticeably more tasty tomatoes next year.
C. The study provides a road for where to plant tomatoes with better flavor.
D. The study has fixed all the genes of existing tomatoes.

A recent study, published in last week’s Journal of the 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 p.m., 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 night of passenger restrictions, before graduating to full driving privileges.
Graduated 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.
1.Which of the following situations is most dangerous according to the passage?
A．Adults giving a lift to teenagers on the highway after 10 p.m.
B．A teenager getting a lift from a stranger on the highway at midnight.
C．Adults driving with three or more teenage passengers late at night.
D．A teenager driving after midnight with passengers in the car.
2.According to Robert Foss, the high death rate of teenage drivers is mainly due to ________.
A．their frequent driving at night
B．their lack of driving experience
C．their improper way of driving
D．their driving with passengers
3.According to Paragraph 3．which of the following statements is TRUE?
A．The licensing authorities are partly responsible for teenagers' driving accidents.
B．Driving is a skill too complicated for teenagers to learn.
C．Restrictions should be imposed on teenagers applying to take driving lessons.
D．Teenagers should spend more time learning to drive.
4.The most suitable measure to be taken to reduce teenagers' driving accidents is that ________ .
A．driving in the presence of an adult should be made a rule
B．they should be prohibited from taking on passengers
C．the licensing system should be improved
D．they should not be allowed to drive after 10 p.m.

According to a study published in the pre-print website bioRxiv, a team of Israeli scientists recorded tomato and tobacco plants producing sound frequencies which humans cannot hear in stressful situations—such as when they experienced a lack of water or their stems were cut. The team identified the sounds with microphones placed around 10 centimeters (around four inches) away from the plants, though the scientists say the noises could potentially be heard several feet away by some mammals and insects, such as mice.
Plants exposed to drought stress have been shown to experience cavitation (空化现象)— a process where air bubbles (气泡)form, expand and explode inside tissue that transports water. These explosions produce sound, but they have only ever been recorded using devices directly connected to the plants. The latest study, meanwhile, is the first to identify plants making sounds which can be detected over a distance. And the researchers say that cavitation could potentially be the source of these sounds.
The team detected the tomato plants made 35 sounds an hour on average when they were exposed to drought conditions, while the tobacco plants produced 11. When the stems of the plants were cut, the tomato plants made 25 sounds an hour on average and the tobacco plants produced 15. As a comparison, unstressed plants made less than one sound hour on aver-age, according to the study.
The team say that while they only tested tomato and tobacco. It's possible that other plants could also produce sounds, adding that the latest findings could have implications for agriculture. ''Plant sound emissions could offer a novel way for monitoring crops' water state—a question of vital importance in agriculture, '' the authors wrote in the study. ''More Precise irrigation can save up to 50 percent of the water consumption and increase the output, with dramatic economic implications. ''
''According to Anne Visscher from the Royal Botanic Gardens, Kew, in the U. K., the idea that the sounds could be used in precision agriculture is 'practical' though she urges caution regarding the Israeli team's suggestion that other animals could hear the sounds at a distance, '' New Scientist reported.
1.What do the Israeli scientists find about plants?
A.Stressed plants tend to lack water.
B.Some plants can understand humans' sounds.
C.Stressed plants can make more frequent sounds.
D.Some mammals and insects can communicate with plants.
2.What can we learn about cavitation?
A.It may contribute to the plants' sounds.
B.It may lead to plants experiencing drought.
C.It is determined by the number of air bubbles.
D.It was identified and recorded for the first time.
3.How many sounds do the tomato plants make per hour on average when cut?
A.11. B.15.
C.25. D.35.
4.What's Anne Visscher's attitude to applying the study to agriculture?
A.Supportive. B.Cautious.
C.Reserved. D.Opposed.
