Prehistoric men and women enjoyed a more varied diet than people do now, since they ate

species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: Only the three major cereals (谷物类食物) and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something？ After all, there are 800 000 species of plant on earth.

1.Most of us have come to expect().

A、no variation in our diet

B、a reduction in food supplies

C、a specialist diet

D、food conforming to a set standard

2.The conclusion seems to be that we().

A、could make use of more natural species

B、don't cultivate the right kind of food

C、produce more food than we need

D、cultivate too many different species

3.In prehistoric times people().

A、ate much more than we do today

B、lived mainly on plant food

C、had a wide-ranging diet

D、were more fussy about what they ate

4.The specialization of food was started by().

A、the emergence of supermarkets

B、the rise of agriculture

C、the rich countries

D、the modern shops

5.According to the passage, people in the West today survive on().

A、carrots and tomatoes

B、several thousand types of plants and cereals

C、a very small number of cultivated foods

D、special species planted one thousand years ago

根据材料，回答下列各题： Why Teenagers Really Do Need an Extra Hour in Bed？ A) "Making tee

ns start school in the morning is cruel ," brain doctor claims. So declared a British newspaper headline in 2007 after a talk I gave at an academic conference. One disbelieving reader responded: " This man sounds brain-dead. " B) That was a typical reaction to work I was reporting at the time on teenage sleep patterns and their effect on performance at school. Six years on there is growing acceptance that the structure of the academic day needs to take account of adolescent sleep patterns. The latest school to adopt a later start time is the UCL Academy in London; others are considering following suit. C) So what are the facts about teenage sleep, and how should society adjust to these needs？ The biology of human sleep timing, like that of other mammals, changes as we age. This has been shown in many studies. As adolescence begins, bedtimes and waking times get later. This trend continues until 19.5 years in women and 21 in men. Then it reverses. At 55 we wake at about the time we woke prior to adolescence. On average this is two hours earlier than adolescents. This means that for a teenager, a 7 a.m. alarm call is the equivalent of a 5 a.m. start for a person in their 50s. D) Precisely why this is so is unclear but the shifts related with changes in hormones (荷尔蒙) at adolescence and the decline in those hormones as we age. However, biology is only part of the problem. Additional factors include a more relaxed attitude to bedtimes by parents, a general disregard for the importance of sleep, and access to TVs, DVDs, PCs, gaming devices, cell phones and so on, all of which promote alertness and eat into time available for sleep. E) The amoount of sleep teenagers get varies between countries, geographic region and social class, but all studies show they are going to bed later and not getting as much sleep as they need because of early school starts. F) Mary Carskadon at Brown University in Providence. Rhode Island, who is a pioneer in the area of adolescent sleep, has shown that teenagers need about 9 hours a night to maintain full alertness and academic perforruance. My own recent observations at a UK school in Liverpool suggested many were getting just 5 hours on a school night. Unsurprisingly. teachers reported students dozing in class. G) Evidence that sleep is important is overwhelming. Elegant research has demonstrated its critical role in memory improvement and our ability to generate wise sohitions to complex problems. Sleep disruption may increase the level of the stress. Excited behaviors, lack of empathy, sense of humor and mood are similarly affected. All in all, a tired adolescent is a moody, insensitive, angry and stressed one. Perhaps less obviously, sleep loss is associated with metabolic (新陈代谢的) changes. Long-term lack of sleep might be an important factor for negative conditions such as diabetes (糖尿病), overweight and high blood pressure. H) Adolescents are increasingly using stimulants to compensate for sleep loss, and caf, feinated (含咖啡咽的) and/or sugary drinks are the usual choice. So a caffeinated drink late in the day delays sleep at night. Tiredness also increases the likelihood of taking up smoking. I) In the US, the observation that teenagers have biologically delayed sleep patterns compared to adults prompted several schools to put back the start of the school day. An analysis of the impact by Kyla Wahlstrom at the University of Minnesota found that academic performance was enhanced, as was attendance. Sleeping in class declined, as did self-reported depression. In the UK, Monkseaton High School near Newcastle instituted a 10 am start in 2009 and saw a progress in academic perfomance. J) However, a later start by itself is not enough. Society in general, and teenagers in particular, must start to take sleep seriously. Sleep is not a luxury but a ftmdamental biological need, enhancing creativity, productivity, mood and the ability to interact with others. K) ff you are dependent upon an alarm clock, or parent, to get you out of bed ; if you take a long time to wake up; if you feel sleepy and impatient during the day; ff your behavior. is overly impulsive, it means you are probably not getting enough sleep. Take control. Ensure the bedroom is a place that promotes sleep-dark and not too warm-dont text, use a computer or watch TV for at least half an hour before trying to sleep avoid avoid bright lights. Try not to nap during the day, and seek out natural light in the morning to adjust the body clock and sleep patterns to an earlier time. Avoid caffeinated drinks after lunch. L) It is my strongly held View, based upon the evidence, that the efforts of dedicated (专注的，投入的) teachers and the money spent on school facilities will have a greater impact and education will be more rewarding when, collectively, teenagers, parents, teachers and school governors start to take sleep seriously. In the universal language of school reports: we must do better. In the US and UK, several schools that have delayed the start of the school day witnessed a progress in academic performance.

Is that 6 a.m. wokeout getting in the way of good sleep？ Don't think your fat cell

s won't notice. A new study published in The Annals of Internal Medicine (a medical journal) finds that inadequate shut-eye has a harmful effect on fat cells, reducing their ability to respond to insulin (胰岛素) by about 30 percent. Over the long-term, this decreased response could set the stage for type-2 diabetes (a medical condition in which someone has too much sugar in his or her blood), fatty liver disease and weight gain.

The study adds to a growing body of evidence that there' “an intimate relationship between the amount of sleep we get and our ability to maintain a good, healthy body weight,” says sleep expert Helene Emsellem, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland. But Americans don't seem to be getting the message that we need seven to nine hours par night. More than 1 in 5 of us, according to a report from the Centers for Disease Control and Prevention, is getting six or fewer hours of sleep per night, on average.

So how did researchers study fat cells in the Annals paper？ Matthew Brady of the University of Chicago and a group of colleagues selected and persuaded seven volunteers to take part in the research project. They were all young, thin and healthy and agreed to sleep for eight nights in a sleep lab. “For four nights they were allowed to stay in bed for 8.5 hours a night,” says Brady. Then, a month later, they came back for four additional nights——but this time they were allowed just 4.5 hours of sleep per night. And after each visit, researchers got a sample of their fat. Brady explains that the fat cells responded significantly to the loss of sleep. “I was very surprised to be honest,” he says.

Bad things can happen when fat cells become less responsive to insulin. “Fat cells are actually your friend,” he says. “They're there to store lipids (血脂).” When lipids stay inside the cells, your body can utilize the fat when you're exercising or sleeping or going about your day. “However, when fat cells stare to become insulin resistant, the lipids star to leach out of the fat cells and rise in the bloodstream,” Brady says.

1. According to the passage, lack of sleep for a long while can probably lead to all of the following EXCEPT {A; B; C}.

A. heart disease

B. weight gain

C. diabetes

2. The main idea of the third paragraph is {A; B; C}.

A. We will be in trouble if our fat cells become less responsive to insulin.

B. More and more studies are done to study the link between sleep and weight.

C. More than 20% of Americans are not getting enough sleep.

5. Which of the following is an appropriate title for this passage？{A; B; C}

A. Poor Sleep May Lead to Too Much Stored Fat and Disease

第7题

There is much discussion today about whether economic growth is desirable. At an earli

er period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast.

Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.

People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.

This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.

1.We may infer from the context that "proponents “ (Paragraph 3)most probably means .

[A] arguments in support of something

[B] disagreement

[C] people who argue for something

[D] people who argue against something
