Part Ⅲ 

Reading Comprehension 

( 40 minutes )

Section A

Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

Questions 26 to 35 are based on the following passage.

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  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 it before. 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（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’t feel any improvement in my condition in the first couple of days, but after a few more regular visits to the doctor, my cough started to  35  . Then, within a matter of weeks, it was completely gone!

A) deepen                    I)remedies B) experiences                J) scared C) hesitant                D) inconvenience              K) sensitive       E) lessen                     L) sink          F) licenses                    M) temporary G)pressured                   N) tremble H) recommended               O) worse

Section B

Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information 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.

How a Poor, Abandoned Parisian Boy Became a Top Chef

A) When you drop a piece of food on the floor, is it really OK 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 particular 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 on 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 OK 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 the 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 kitchen, 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 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 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 made 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 transfer 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 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 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 surface 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, 45-70% of bacteria were.

J) Last year, a study 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 have 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 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 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 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 food, 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 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 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 contamination 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. Chances 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. Researchers 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: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

Passage One

Questions 46 and 50 are based on the following passage.

The latest in cat research 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 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 the 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 noise 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 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 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 and 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 published 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’ response to the noise from the containers?

A) Their inborn sensitivity to noise.

B) Their unusual sense of direction.

C) Their special ability to perceive.

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 their 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.

B) They view the world as normal.

C) They do what they prefer to do.

D) They are curious about everything.

考试方面的学习建议:听力： 听力部分是在考试里面最容易拿分数的部分。最开始的时候，我连听voa special english都很困难。我的方法是：一个sp要听4-5次，把里面不懂的英语单词的发音，含义全部搞清楚，然后每天坚持2个小时的听力训练，狂攻sp。如果没事，就拿一个MP3吊耳朵，让自己慢慢习惯英语语境。2个月后，我听了一盘四级英语考试磁带，发现自己原来根本听不明白的东西变的简单了。所以还是绝对值得的。

2：单词 这是一个老生常谈的话题，大家知道，单词是英语的础，没有单词，就好象建大厦没有砖头，只能幻想空中楼阁。但是被单词又被大家认为是最难，最枯燥的事情。基础好的朋友可以通过阅读学单词，但是对基础不好的，这点根本行不通。整篇文章都看不太明白，还谈什么学单词呢？既然咱们现在水平不行，就要拿出比别人更的努力。我背单词的草稿纸已经放满了一个大箱子。 大家肯定有这种经验，前不久背了的单词，很快就忘记了，那么该怎么办呢？我当时是每天固定背30-40个左右的单词，第二天复习前一天的单词，然后每个礼拜天，花1小时把一个礼拜的单词复习一下，每一个月又花几个小时把一个月的单词复习一次。不懂的单词全部记下来。

3：阅读 阅读在我看来，就是通过增加阅读量，提高阅读速度，掌握一定的阅读技巧。 最开始的时候，因为基础比较差，太难的文章肯定不适合基础差的朋友。先可以看一些"书虫"（高中水平）一类的改编小说，练练感觉。当单词量积累到一定程度以后，就可以正式开始提高阅读水平了。把题里的句子、单词都弄明白，并且对其中的难句做一定的分析，特别是语法结构。这里有一个问题：最开始你做题目的时候准确率会很低，千万别灰心，坚持下去，从每一篇阅读里面吸取精华，很快就会发现：阅读真的没那么可怕。

4:作文 这里我记得一个提高班的英语老师说过的一句话：读书破万卷，下笔如有神。作文一个字:背！如果你背了很多很多范文，作文不会低分的。但是我建议在背的同时，可以用一个小本子，把一些很精彩的句子抄下来，经常看看，并举一反三。同样一个句子，用在不同的地方，会有不同的效果最后:要对自己有信心，相信自己，付诸努力，坚持下来，你一定能行
