People will be alert(警觉的)and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging in the brain that they are putting the theory to work in their own lives. “The idea is not necessarily to learn to memorize large amounts of information,” says James Fozard, associate director of the National Institute of Ageing. “Most of us don’t need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness.” Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. “The point is, you need to do both,” Cohen says. Intellectual activity actually influences brain-cell health and size.
(1)What is the passage mainly about?()
A. Special mental training for old people.
B. Biochemical changes in the human brain.
C. The influence of intellectual activities on brain-cell size.
D. The importance of mental activities in the efficiency of the brain.
(2)A person who is said to be cognitively healthy should ().
A. be alert and receptive in mind B. who are highly intelligent
C. be good at doing group work D. remember large quantities of information
(3) The findings of James and other scientists in their work ().
A. remain a theory to be further proved B. have been challenged by many other experts
C. are practiced by the researchers themselves D. have been generally accepted
(4)According to Fozard's argument, people can make their brains work more efficiently by ().
A. constantly doing memory work B. making frequent adjustments
C. going through specific training D. taking part in various mental activities
(5) Which of the following statements would Cohen most probably support?()
A. Older people should keep mentally active by challenging their brains.
B. No matter whether it is done in group or alone, mental activity is always good for brain-cell health.
C. Physical strength is more important to older people than mental health.
D. People who engage in more mental activities but less physical ones are always happier.

听力原文：M: What're you doing up so early, Anna？ (19) Have you decided to take up jogging in the park like me？
W: No, Mike. You know I really can't stand jogging. I've joined a yoga class at our local fitness center. I hear it's a great way to stay fit. Want to join me？
M: No way! Yoga is for girls. I'd rather do some weights at the gym than (21) distort my body into painful postures.
W: Come on, there's more to yoga than that! (20) It's perfect for physical and spiritual well-being. It also helps your body become more flexible.
M: No thanks—I think all of this is (21) just a moneymaking trick. I'm telling you Anna, don't buy into it!
W: Mike, we just learn three new postures every day and do some meditation. My yoga coach is going to teach us about breathing today. Did you know that we don't even breathe properly anymore？
M: Count me out! I don't need anyone to tell me how to breathe! Just because celebrities are doing yoga, everyone's running after it.
W: That's not true! You're always reluctant to try something new. Give it a chance~you might enjoy it.
M: Okay, but (22) only if you promise I would end up with a body like what exactly Stallone has got!
(23)
A．Doing yoga.
B．Jogging.
C．Doing some weights.
D．Learning breathing.

W: Hmm, it sounds interesting. Please share with us. What does it mean？
M: Essentially, what it means is that as you are building a house, you try to leave the landscape feature on the land, especially the vegetation in the original condition. So what you are not doing is the usual practice of "land scraping". By which I mean literally scraping or cleaning the land of any and all the original plants.
W: Why is the approach called Envelop Building？
M: Good question! Because instead of clearing everything away, you let your original landscape elements envelop or surround your house. Let the vegetation physical features such as hills and slopes or interesting rock formations, constitute a significant part of the character of the building site. The design of the house should take these features of the land into account.
W: Any more information about Envelop Building？ Is it a recent technology？
M: Actually, integrating your original wild landscape with a house is not that new. The famous American architect Wright was doing it about 65 years ago. Envelop Building is not as easy as it sounds though. It's not just that you build your house and leave the land alone. By building, you are already damaging the original landscape. But as architects, we should try to work with environment, not against it. A creative architect can find ways to incorporate natural landscape into the overall design.
W: I guess this technology will be acknowledged by more architects.
(23)
A．Eliminating the original vegetation from the building site.
B．Making the houses in an area similar to one another.
C．Deciding where a house will be built.
D．Surrounding a building with wildflowers and plants.

Meanwhile, poorer nations have enjoyed some success in their battles against malnutrition and famine. Bat, according to research presented at the annual meeting of the American Association for the Advancement of Science, it is more a case of being out of the frying pan and into the fire. The most striking example actually in the poor world comes from the Pacific islands, home of the world's most obese communities. In 1966, 14% of the men on this island were obese while 100% of men under the age of 30 in 1996 were obese.
This increase in weight has been uneven as well as fast. As a result, undernourished and overnourished people frequently live cheek by jowl (面颊). The mix can even occur within a single household. A study of families in Indonesia found that nearly 10% contained both the hungry and the fat. This is a mysterious phenomenon, but might have something to do with people of different ages being given different amounts of food to eat.
The prospect of heading off these problems is bleak. In many affected countries there are cultural factors to contend with, such as an emphasis on eating large meals together, or on food as a form. of hospitality. Moreover, there is a good measure of disbelief on the part of policymakers that such a problem could exist in their countries. Add to that reluctance on the part of governments to spend resources on promoting diet and exercise while starvation is still a real threat, and the result is a recipe for inaction. Unless something is done soon, it might not be possible to turn the clock back.
The first sentence of the passage most probably implies that ________.
A．many Americans are obsessed with the rising temperature in their bathroom
B．more people are overweighed in the United States
C．people are doing more physical exercises with the help of scales
D．youngsters become taller and healthier thanks to more activities
第5题
A．By going on a diet.
B．By doing physical exercise.
C．By having fewer meals.
D．By eating fruit and vegetables.

截取一段明文如下:
The Mutual Information Analysis (MIA) is a generic side channel distingui she that has been introduced at CHES 2008. This paper brings three contributions with respect to its applicability to practice. First, we emphasize that the MIA principle can be seen as a toolbox in which different (more or less effective) statistical methods can be plugged in. Doing this, we introduce interesting altematives to the original proposal. Second, we discuss the contexts in which the MIA can lead to successful key recoveries with lower data complexity than classical attacks such as, eg. using Pearson's correlation coefficient. We show that such contexts exist in practically meaningful situations and analyze them statistically. Finally, we study the connections and differences between the MIA and a framework for the analysis of side- channel key recovery published at Eurocrypt 2009. We show that the MIA can be used to compare two leaking devices only if the discrete models used by an adversary to mount an attack perfectly correspond to the physical leakages.

The trouble with the term "behavior" is that it is often taken to refer only to more or less overt, and describable, physical movements and acts. Yet part of language behavior. -- that of understanding spoken or written language, for example -- has little or no physically observable signs. It is true we can sometimes infer that understanding has taken place by the changes that take place in the other person's behavior. When someone has been prohibited from doing something, we may infer that he has understood the prohibition by observing that thereafter he never behaves in that way. We cannot, of course, be absolutely sure that his subsequent behavior. is a result of his understanding; it might be due to a loss of interest or inclination. So behavior. must be taken to include unobservable activity, often only to be inferred from other observable behavior.
Once we admit that the study of language behavior. involves describing and explaining the unobservable, the situation becomes much more complicated, because we have to postulate some set of processes, some internal mechanism, which operates when we speak and understand. We have to postulate something we can call a mind. The study of language from this point of view can then be seen as a study of the specific properties, processes and states of the mind whose outward manifestations are observable behavior; what we have to know in order to perform. linguistically.
This approach to language, as a phenomenon of the individual, is thus principally concerned with explaining how we acquire language, and its relation to general human cognitive systems, and with the psychological mechanisms underlying the comprehension and production of speech: much less with the problem of what language is for, that is, its function as communication, since this necessarily involves more than a single individual.
What is the best title for this passage？
A．Language as Means of Communication
B．Language and Psychology
C．Language and the Individual
D．Language as a Social Phenomenon

Children today not only exist; they have taken more attention, in no place more than in America, and at no time more than now. It is always Kids' Country here. Our civilization is child-centered, child-obsessed. A kid's body is our physical ideal. In Kids' Country we do not permit middle age. Thirty is promoted over 50, but 30 knows that soon his time to be overtaken will come.
We are the first society in which parents expect to learn from their children. Such a topsy-turvy (颠倒)situation has come about at least in part because, unlike the rest of the world, ours is an immigrant society, and for immigrants the only hope is in the kids. In the Old Country, that is Europe, hope was in the father, and how much wealth he could accumulate and pass along to his children. In the growth pattern of America and its ever-expanding frontier, the young man was ever advised to go west; the father was ever inheriting from his son. Kids' Country may be the inevitable result.
Kids' Country is not all bad. America is the greatest country in the world to grow up in because it is Kids' Country. We not only wear kids' clothes and eat kids' food, we dream kids' dreams and make them come true. It was, after all, a boys' game to go to the moon.
If in the old days children did not exist, it seems equally true today that adults, as a class, have begun to disappear, condemning all of us to remain boys and girls forever, jogging and doing push-ups against eternity.
The author uses the example of the Renaissance painting to show that ______.
A．adults were smaller and smaller now because they had many things to do
B．adults expressed less concern for their children
C．children looked and acted like adults at that time
D．children were not allowed to appear in family paintings
第10题
Weight Control: The Power of Healthy Choices
What Is a Healthy Weight for Me？
This is a tough question to answer. Even though many people talk about weight, what really matters is how much of your body weight is fat. The body mass index (BMI) is an approximate measure of body fat. It is based on your height and weight. A BMI between 19 and 25 is considered a normal amount of body fat. If someone's BMI is 25 to 29.9, that person is said to be overweight. A person is said to be obese (过度肥胖的) if his or her BMI is 30 or higher. The higher your BMI is, the greater your risk for diseases such as diabetes, heart disease, arthritis, and certain cancers is.
Some Causes That Can Lead to Being Overweight
Having weight problems in your family.
Eating when you're lonely, sad, bored or stressed.
Eating because you feel pressured by friends or family to eat.
Using food for recreation, or eating just because food is available.
Taking medicine that makes you feel hungry.
Having hormone problems that slow your metabolism (how fast your body burns calories).
How Can I Lower My BMI？
The best way to lower your BMI is to reduce the total number of calories you take in and to be more physically active.Long-term success is not about finding the "right" diet. It's about identifying your behaviours that have contributed to taking in more calories than your body needs. It is also about making a plan to develop healthier eating and physical activity habits. For example, you may eat when you're under stress rather than when you're hungry. Choosing another activity to do when you feel stressed, such as taking a walk, may help you break the habit of eating at those times.
You're more likely to make changes in your habits if you set a specific goal for yourself. For example, instead of saying "I'm going to lose 20 pounds", decide that you'll be more active every other day of the week. Be specific about what kind of activity you'll do and which days you'll do it. Your new goal might be: "During my lunch hour on Mondays, Wednesdays and Fridays, I'm going to walk for half an hour in the park." Once your new healthy behaviour becomes a habit, you can move on to another goal.
Why Is Physical Activity a Big Deal？
Physical activity builds muscles, so even if you don't lose pounds, you will look and feel better when you are more active. Being active also reduces your risk of chronic diseases like heart disease and diabetes, even if you are overweight.
What Is the Best Kind of Activity？
First, ask your family doctor if there is any kind of physical activity that you should not do. Being more physically active doesn't mean you need to have a formal or complicated exercise program. Remember that the best kind of activity is the kind that you'll keep doing. Whatever activity you choose, try to do it for at least 30 minutes per day on most days of the week.
Aerobic exercises, such as swimming, walking or jogging, raise your heart rate and help burn calories. The longer you exercise, the more fat your body will burn. Walking can be very helpful even if you don't walk fast.
Light weight training also has many health benefits. It helps add muscle mass to your body. Muscle burns calories faster than fat does.
How Can I Change My Eating Habits？
Change them one at a time. For example, start by training yourself to eat without doing anything else at the same time.Focus on enjoying the taste and smell of your food by eating more slowly. Don't watch TV, talk on the phone or drive a car while you eat.
Healthy Habits
