第三節回答問題（共3小題；每小題2分，滿分6分）
閱讀下面短文，根據第58至第60小題的具體要求，盡可能簡要回答問題，并將答案轉寫到答題卡上。
If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
58. What is the main reason for one is poor memory? (回答詞數不超過8個)
59. What will happen if you do not use your arms or legs for some time? (回答詞數不超過5個)

I know what you’re thinking: pizza（比薩餅）？ For breakfast? But the truth is that you can have last night’s leftovers in the a.m. if you want to.

I know lots of women who skip breakfast (不吃早飯), and they have a ton of different excuses for doing it. Some say they don’t have time, others think they’re “saying” calories (卡路里)，still others just don’t like breakfast food.

學科But the bottom line is that eating in the morning is very important when you’re trying to lose weight .“Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R.D. , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.

學科Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.

So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers – it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow.” I put away the leftovers instead of eating more that night. Try it … you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.

小題1:The word “leftovers” in paragraph I probably means ______.

A．food remaining after a meal	B．things left undone
C．meals made of vegetables	D．pizza topped with fruit

小題2:What can we infer from the text?

A．Working women usually have breakfast in a hurry.

B．Many people have wrong ideas about breakfast.

C．There are some easy ways of cooking a meal.

D．Eating vegetables helps save energy.

小題3:According to the last paragraph, it is important to _______.

A．eat something for breakfast	B．be careful about what you cat
C．heat up food before eating it	D．cat calorie-controlled food

小題4:The text is written mainly for those _______.

A．who go to work early	B．who want to lose weight
C．who stay up late	D．who eat before sleep

These needles may possibly do you some good.” I agreed. In a moment, he had taken out a few needles from his purse. Without a moment’s delay, he fixed a few needles into the skin on my head here and there, Before long, I felt thoroughly relieved(緩解疼痛).

Although we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.

There are three kinds of flu virus, known as A, B and C. Flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies （抗體） which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability（可變性） is less developed in the flu B virus, which affects only human beings. Flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918 and 1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence （病毒性）, the ease with which it can be transmitted and the strength of the opposition it encounters （遇到）. Scientists, however, have a reliable general picture of the world situation.

72. Which of the following is the most appropriate title for the passage?

A. Symptoms of Flu B. Man VS Flu Virus

C. WHO: The Major Organization against Flu Virus D. Variability of Flu Virus

73. What does the author say about the flu B virus?

A. B Virus is relatively stable and causes mild infections that do not spread far through the population.

B. B Virus is unstable, and is responsible for the epidemics that cause frequent concern.
C. B virus is extremely unstable and is responsible for some of the worst outbreaks of the disease.

D. B virus has a very developed variability, and it affects only human beings.

74. Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads?

A. The strength of the virus. B.The ease with which the virus can be transmitted.

C. The strength of the opposition. D.The immunity the virus can bring about.

75. This article is quite probably ________.

A. a piece of news B. a special science report

C. an introduction to a disease D. a scientific fiction

Eat healthier. Exercise twice a week. Read more books. Lose weight. We make the same resolutions(決心) every year, but most of us fail, dying out after only a few days or , at best, weeks. Even the most successful among us crash and burn when it comes to personal change. President-elect Barack Obama struggles to remove his cigarette habit.
Professionals who help people make changes in their lives suggest the change is determined not by one's surroundings, but one's mind. Beginning with small goals or steps usually leads to a bigger payoff later, they say. But they caution that the experience is different for everyone.
"People are more likely to make positive changes in their lives not only when their friends do, but when their friends of friends do, and when their friends of friends of friends do," said Nicholas Christakis, a professor of medical sociology at Harvard University. "People are better able to make changes in their lives - lose weight, quit smoking, become happy - when they do this with a large number of other people, and so taking advantage of your social network ties can result in a magnification of your own efforts."
Jhonny Augustin understands that well. His resolution for 2008 was to shed 30 pounds from his 237-pound frame. But the change didn't come easily. He said,"I'm a huge procrastinator, I kept putting it off until tomorrow. I didn't get to do it until the summer." However , Augustin got inspired when he saw his older brother working out. Today, Augustin weighs 190 pounds.
“Of course, change can happen only if people don't set their expectations too high or try to tackle too many changes at once; one of the biggest mistakes we make is setting unrealistic goals, ”said Dalia Llera, a psychologist and associate professor of counseling and psychology at Lesley University. "You can't accomplish in a few weeks what you haven't accomplished in a few years," said Llera.
46.From the first paragraph we can infer that      .
A.change for a person is challenging
B.famous people have great determination
C.most people don’t want to change themselves
D.personal change is beyond belief
47.It is known from Nicholas christkis that      .
A. making a change is easier with support from a cheerful group of friends
B. social networks have great effect on one’s change
C. people who have the same attitude often get together
D. people’s mood can contribute to their efforts
48.The word “procrastinator” in Paragraph 4 refers to those who      .
A. have great determination to make a change
B. have no desire to do something great
C. put off work especially because of laziness
D. have habitual carelessness and laziness
49.According to the passage, Dalia Liera suggested that      .
A. people should understand their goals well
B. people should try their best to change themselves
C. people should have confidence and positive habits
D. people should start with setting small goals to meet
50.The passage is mainly about      .
A. the reason why losing weight is so hard
B. the effect of the positive change
C. the attitudes towards change in life
D. the ways of making a change

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蠑螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神經束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were                    B. whether they would grow back
C. how long it would take to re-grow    D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins.         B. Proteins similar to n-AG.
C. Stem cells and proteins.              D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in                      B. shows where researchers got their new ideas
C. states the author’s opinion           D. describes the result of researchers’ studies
