10、e was invited to a 40th birthday party. The time printed on the invitation was 7:30pm. Jane went off with her husband, expecting a merry evening of wine, food, and song.By 9:45, everybody was having great fun, but no food had appeared. Jane and David were restless. Other guests began whispering that
11、 they, too, were starving. But no one wanted to leave, just in case some food was about to appear. By 11:00, there was still no food, and everyone was completely off their heads. Jane and David left hungry and angry.Their experience suggests that the words in the printed invitations need to be made
12、clearer. Everyone reads and understands the invitations differently. Most of us would agree that 6:30 -8:30pm means drinks only, go out to dinner afterwards; 8:00pm or 8:30pm means possible dinner, but 9:30pm and any time thereafter means no food, eat beforehand, roll up late.But this is not always
13、the case. If asked to a students party at 6:30pm, it is normal for guests not to appear before midnight, if at all, and no one cares. Being the first to arrive - looking eager - is social death. When my mother is asked to a party for 6:30, she likes to be there, if not on time, then no later than se
14、ven. My age group (late thirties) falls somewhere between the two, but because we still think were young, were probably closer to student-time than grown-up time.The accepted custom at present is confusing, sometimes annoying, and it often means you may go home hungry, but it does lend every party t
15、hat precious element (成分) of surprise.21. The underlined words “off their heads” probably mean_. A. tired B. crazy C. curious D. hopeless22. Jane and Davids story is used to show that_.A. party-goers usually get hungry at parties B. party invitations can be confusingC. people should ask for food at
16、parties D. birthday parties for middle-aged people are dull23. According to the writer, people in their late thirties_. A. are likely to arrive late for a party B. care little about the party time C. havent really grown up yet D. like surprises at partiesBPeople may set an alarm on the phone or cloc
17、k that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music .The study, carried out by researchers in Australia, inv
18、olved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, We are very surprised by these findings as one might expect a harsh beeping sound to be more successful” at waking up a person.
19、Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertias harmful effects on human performance later in the day.Not everyone will experience t
20、he full effect. But for those who do, care should be taken when performing duties that require a top performance within this period, he said. This includes dangerous tasks like driving or riding our bikes shortly after waking up. The same is true for people who work in dangerous situations shortly a
21、fter they wake, including firefighters and pilots.So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a beeping alarm. McFarlane said that the changes over ti
22、me between the music tones may help increase a persons attention when waking from sleep.And is there a kind of music that is best to wake up to? There may be, McFarlane said. We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using inc
23、lude “ Close to me by the Cure and Borderline by Madonna.No matter how you wake up, experts say, the amount of sleep you get also matters - a lot.24. Which of the following might be the best title for the text?A. What is grogginess? B. Why are musical alarms better?C. Which music is the best? D. How
24、 can we overcome grogginess?25. The paragraph following this passage is likely to focus on _.A. examples of good musical alarmsB. more findings of the application of musicC. explanations about why music is more helpfulD. suggestions on how to sleep well and feel fresh each morning26. In which sectio
25、n of a magazine may you find the passage?A. HealthB. FictionC. Technology D. EntertainmentCBritish anthropologists Russell Hill and Robert Barton of the University of Durham, after studying the results of one-on-one boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling matches at the Ol
26、ympic Games, conclude that when two competitors are equally matched in fitness and skill, the athlete wearing red is more likely to win. Hill and Barton report that when one competitor is much better than the other, colour has no effect on the result. However, when there is only a small difference b
27、etween them, the effect of colour is enough to tip the balance. The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant. Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar res
28、ults in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchells work shows that the powerful malesthe ones who are more successful with femaleshave a brighter red nose than other males. As well as the studi
29、es on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds success with female zebra finches. Zebra finches already have bright red beaks (鸟喙), so this study suggests
30、 that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from the University of Glasgow say that the birds brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, and his colleagues think they have found proof that bright red or orange bea
31、ks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females. Meanwhile, what about those athletes who win in their
32、 events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing? 27. According to their research, Hill and Barton conclude that _
33、. A. the colour of clothing has an effect on most sport eventsB. red should be the choice of colour for clothing in sportsC. red plays a role when competitors are equally capableD. athletes perform better when surrounded by bright red28. The underlined word “tip” in Paragraph 2 is closest in meaning
34、 to _. A. achieveB. seekC. keepD. change29. The example of the blue footed booby proves that _. A. male birds use different body parts to draw attention B. red is not the only colour to attract female birds C. blue gives female birds the same advantage D. blue can indicate how healthy a bird is30. W
35、hat is the best title for the passage? A. What Colour Implies More Power? B. A Tip on Clothing. C. Need to Change the Rules in Sports? D. Red Is for Winners.第二节（共5小题; 每小题2分, 满分10分）根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Teenagers are supposed to be moody, right? One moment they are happy and laughi

This time Ill say something about memory. Since memory plays an important role in our life, scientists are increasingly interested in research o
87、n how to improve memory. Here are some factors they believe to be important in developing memory. To begin with, you must take special care in your daily life. Food, for example, is very important. Some vegetables and fruits are necessary for your memory to work properly. Another factor is water. It
88、 helps to keep the memory systems working properly, especially in old people. According to Dr. Rosewell, lack of water in the body has an immediate and strong effect on memory. It can cause confusion and other thought difficulties. Sleep also plays an important role. To be able to have a good memory
89、, we must allow the brain to have plenty of rest. While sleeping, the brain no longer controls the senses, and starts to review and store the information one has received. Lack of sleep would make one feel tired and would weaken ones ability to concentrate. Also, ones ability to store information would be affected.
