Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter on Answe

4、r Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once. A few months ago, I was down with a terrible cold which ended in a persistent bad cough. No matter how many different _ 26_ I tried, I still couldn't get rid of the cough Not only did it

5、 _ 27_ my teaching but also my life as a whole Then one day after class, a student came up to me and _28_ traditional Chinese medicine. From her description, Chinese medicine sounded as if it had magic power that worked wonders. I was _ 29_ because I knew so little about it and have never tried it b

6、efore. Eventually, my cough got so much _ 30_ that I couldn't sleep at night, so I decided to give it a try. The Chinese doctor took my pulse and asked to see my tongue, both of which were new _ 31_ to me because they are both non-existent in Western medicine. Then the doctor gave me a scraping（

7、刮） treatment known as "Gua Sha". I was a little _ 32_ at first because he used a smooth edged tool to scrape the skin on my neck and shoulders A few minutes later, the _ 33_ strokes started to produce a relieving effect and my body and mind began to _ 34_ deeper into relaxation. I didn'

Each statement contains information given in one of the paragraphs Identify the paragraph from which the inform

10、ation is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. Is it really ok to eat food that's fallen on the floor? A) When you drop a piece of food on the floor, is it really OK

11、to eat if you pick it up within five seconds? An urban food myth contends that if food spends just a few seconds on the floor, dirt and germs won't have much of a chance to contaminate it. Research in my lab has focused on how food becomes contaminated, and we've done some work on this parti

12、cular piece of wisdom. B) While the "five-second rule" might not seem like the most pressing issue for food scientists to get to the bottom of, it's still worth investigating food myths like this one because they shape our beliefs about when food is safe to eat. C) So is five seconds o

13、n the floor the critical threshold（门槛）that separates a piece of eatable food from a case of food poisoning? It's a bit more complicated than that. It depends on just how many bacteria can make it from floor to food in a few seconds and just how dirty the floor is. D) Wondering if food is still O

14、K to eat after it's dropped on the floor is a pretty common experience. And it's probably not a new one either A well-known, but inaccurate, story about Julia Child may have contributed to this food myth. Some viewers of her cooking show, The French Chef, insist they saw Child drop lamb on t

15、he floor and pick it up, with the advice that if they were alone in the kitchen, their guests would never know. E) In fact it was a potato pancake, and it fell on the stovetop, not on the floor Child put it back in the pan, saying, "But you can always pick it up and if you're alone in the k

16、itchen, who's going to see it?" But the misremembered story persists. It's harder to pin down the origins of the oft-quoted five- second rule, but a 2003 study reported that 70% of women and 56% of men surveyed were familiar with the five-second rule and that women were more likely than

17、 men to eat food that had dropped on the floor. F) So what does science tell us about what a few moments on the floor means for the safety of your food? The earliest research report on the five-second rule is attributed to Jillian Clarke, a high school student participating in a research project at

18、the University of Illinois. Clarke and her colleagues introduced bacteria to floor tiles（瓷砖）and then placed cookies on the tiles for varying times. They reported bacteria were transferred from the tiles to the cookies within five seconds, but didn't report the specific amount of bacteria that ma

19、de it from the tiles to the food. G) But how many bacteria actually transfer in five seconds? In 2007, my lab at Clemson University published a study in the Journal of Applied Microbiology. We wanted to know if the length of time food is in contact with a contaminated surface affected the rate of tr

20、ansfer of bacteria to the food. To find out, we introduced bacteria to squares of tile, carpet or wood. Five minutes after that, we placed either bacon or bread on the surface for 5, 30 or 60 seconds, and then measured the number of bacteria transferred to the food. We repeated this exact procedure

21、after the bacteria had been on the surface for 2, 4, 8 and 24 hours. H) We found that the number of bacteria transferred to either kind of food didn't depend much on how long the food was in contact with the contaminated surface-whether for a few seconds or for a whole minute. The overall number

22、 of bacteria on the surface mattered more, and this decreased over time after the initial introduction. It looks like what's at issue is less how long your food stays on the floor and much more how contaminated with bacteria that patch of floor happens to be. I) We also found that the kind of su

23、rface made a difference as well. Carpets, for instance, seem to be slightly better places to drop your food than wood or tile. When a carpet was contaminated, less than 1% of the bacteria were transferred. But when the food was in contact with tile or wood, 48-70% of bacteria were. J) Last year, a s

24、tudy from Aston University in the UK used nearly identical parameters（参数）to our study and found similar results. They also reported that 87% of people asked either would eat or had eaten food fallen on the floor. K) Should you eat food fallen on the floor then? From a food safety standpoint if you h

25、ave millions or more bacteria on a surface, 0. 1% is still enough to make you sick. Also, certain types of bacteria are extremely harmful, and it takes only a small number to make you sick. For example, 10 bacteria or less of an especially deadly strain of bacteria can cause severe illness and death

26、 in people with compromised immune systems. But the chance of these bacteria being on most surfaces is very low. L) And it's not just dropping food on the floor that can lead to bacterial contamination. Bacteria are carried by various "media", which can include raw food, moist surfaces

27、 where bacteria have been left, our hands or skin and from coughing or sneezing（打喷嚏）. Hands, foods and utensils（器皿）can carry individual bacteria living in communities contained within a protective film. These microscopic layers of deposits containing bacteria are known as biofilms and they are found

28、 on most surfaces and objects. Biofilm communities can harbor bacteria longer and are very difficult to clean. Becteria in these communities also have an enhanced resistance to sanitizers（清洁剂）and antibiotics compared to bacteria living on their own. M) So the next time you consider eating fallen foo

29、d, the odds are in your favor that you can eat it without getting sick. But in the rare chance that there is a micro-organism that can make you sick on the exact spot where the food dropped, you can be fairly sure that the bug is on the food you are about to put in your mouth. N) Research or common

30、sense tells us that the best thing to do is keep your hands, utensils and other surfaces clean. 36. A research project found bacteria made their way to the food on the floor in five seconds. 37. Whether food is contaminated depends much on the number of bacteria that get onto it. 38. Food contaminat

31、ion may result from various factors other than food dropping on the floor. 39. Males are less likely than females to eat food that may have been contaminated. 40. The author's research centers around how food gets contaminated. 41. Keeping everything clean is the best way to stay healthy. 42. Ch

32、ances are you will not fall sick because of eating food picked up from the floor. 43. For a long time people have had the experience of deciding whether or not to eat food picked up from the floor. 44. Some strains of bacteria are so harmful that a tiny few can have deadly consequences. 45. Research

33、ers found how many bacteria got onto the food did not have much to do with how long the food stayed on a contaminated floor. Section C Directions: In this section, you will hear a passage three times. When the passage is read for the first time，you should listen carefully for its general idea.When t

34、he passage is read for the second time，you are required to fill in the blanks with the exact words you have just heard. Finally，when the passage is read for the third time，you should check what you have written. Passage One Questions 46 to 50 are based on the following passage. The latest in cat res

35、earch reveals that the lovely animal seems to have a basic grasp on both the laws of physics and the ins and outs of cause and effect. According to a newly published study, cats seem to be able to predict the location of hiding prey（猎物）using both their ears and an inborn（天生的）understanding of how the

36、 physical world works In a recent experiment, Japanese researchers taped 30 domestic cats reacting to a container that a team member shook Some containers rattled（发出响声）; others did not. When the container was tipped over, sometimes an object fell out and sometimes it didn't. It turns out that th

37、e cats were remarkably smart about what would happen when a container was tipped over. When an object did not drop out of the bottom of a rattling container, they looked at it for a longer time than they did when the container behaved as expected. "Cats use a causal-logical understanding of noi

38、se or sounds to predict the appearance of invisible objects," lead researcher Saho Takagi says in a press release. The researchers conclude that cats' hunting style may have developed based on their common-sense abilities to infer where prey is, using their hearing. Scientists have explored

39、 this idea with other endearing creatures: babies. Like cats, babies appear to engage in what's called "preferential looking"looking longer at things that are interesting or unusual than things they perceive as normal. When babies' expectations are violated in experiments like the

40、ones performed with the cats, they react much like their animal friends. Psychologists have shown that babies apparently expect their world to comply with the laws of physics and cause and effect as early as two months of age. Does the study mean that cats will soon grasp the ins and outs of cause a

41、nd effect? Maybe, Okay, so cats may not be the next physics faculty members at America's most important research universities. But by demonstrating their common sense, they've shown that the divide between cats and humans may not be that great after all. 46. What do we learn from a newly pub

42、lished study about cats? A) They can be trained to understand the physical world. B) They know what kind of prey might be easier to hunt. C) They have a natural ability to locate animals they hunt. D) They are capable of telling which way their prey flees. 47. What may account for the cats' resp

43、onse to the noise from the containers? A) Their inborn sensitivity to noise. C) Their special ability to perceive. B) Their unusual sense of direction. D) Their mastery of cause and effect. 48. What is characteristic of the way cats hunt, according to the Japanese researchers? A) They depend on thei

44、r instincts. C) They wait some time before attack. B) They rely mainly on their hearing. D) They use both their ears and eyes. 49. In what way do babies behave like cats? A) They focus on what appears odd. C) They do what they prefer to do B) They view the world as normal. D) They are curious about

45、everything. 50. What can we conclude about cats from the passage? A) They have higher intelligence than many other animals. B) They interact with the physical world much like humans. C) They display extraordinarily high intelligence in hunting. D) They can aid physics professors in their research wo

46、rk. Passage Two Questions 51 to 55 are based on the following passage. Imagine you enter a car with no steering wheel, no brake or accelerator pedals（踏板）. Under a voice-activated command, you say an address. "The fastest route will take us 15.3 minutes. Should I take it?" You say "yes

47、" and you are on your way. The car responds and starts moving all by itself. All you have to do is sit back and relax. How weird would it be if, one day in the future, everyone had such a car No crazy driving，no insults，no cutting in; traffic laws would be respected and driving much safer. On the other hand, imagine the cost savings for local police enforcement and town budgets without all those spee
