<span style=";font-family:宋体;font-size:14px">When you go to university to study for a degree, you have decided to study professionally, rather than as an amateur; so being a student is now your profession for at least the next four years.</span>
<span style=";font-family:宋体;font-size:14px">This involves a change of attitude in many ways. Although the process has been going on since you went to middle school, the biggest change is going to take place. Now, instead of taking several subjects, you have chosen one major subject because you find it interesting and worth exploring further. The choice was yours. You also have the goal of getting a degree . The degree and the stages you have to pass through to achieve it give you motivation, even though it may become weak from time to time, and not all parts of the course will be exciting; a sure way to lose interest is to do too little work. It is a law of diminishing returns - the less work you do, the less interest you will have and the more bored you will become. So, regular work is needed to keep up your interest as well as to keep pace with new work.</span>
<span style=";font-family:宋体;font-size:14px">Another change is in the relationship with teachers. This may well have changed during middle school and high school, but now the whole context is different. You are no longer forced to slay in school all day, and apart from your class time, you organize your own time and place for studying. You are there to study (an active process) rather than to be taught (passive). Your teachers may or may not urge you, but they do want you to share their interest in the subject and they want you to succeed.</span>
<span style=";font-family:宋体;font-size:14px">Some activities, like discussing and reading, are basic to studying. Make sure that you are doing these efficiently.</span>
<span style=";font-family:宋体;font-size:14px">Group discussions give you a chance to train yourself to speak and discuss more effectively.</span>

In the future you are almost certainly going to have to be good at speaking, so get into the way of talking about your subject now. This is actually more fun than sitting being silently miserable because you are not saving anything. Nobody will think what you say is foolish. Everyone will be thankful not to face awkward silence.</span></span>

Most people have experienced the feeling, after a taxing mental work-out, that they cannot be bothered to make any more decisions. If they are forced to, they may do so intuitively, rather than by reasoning. Such apathy is of ten put down to tiredness; but a study published recently in Psychological Science suggests there may be more to it than that. Whether reason or intuition is used may depend simply on the decision-maker's blood-sugar level—which is, itself, affected by the process of reasoning.
E.J. Masicampo and Roy Baumeister of Florida State University discovered this by doing some experiments on that most popular of laboratory animals, the impoverished undergraduate. They asked 121 psychology students who had volunteered for the experiment to watch a silent video of a woman being interviewed that had random words appearing in bold black letters every ten seconds along the perimeter of the video. This was the part of the experiment intended to be mentally taxing. Half of the students were told to focus on the woman, to try to understand what she was saying, and to ignore the words along the perimeter. The other half were given no instructions. Those that had to focus were exerting considerable serf-control not to look at the random words.
When the video was over, haft of each group was given a glass of lemonade with sugar in it and half was given a glass of lemonade with sugar substitute. Twelve minutes later, when the glucose from the lemonade with sugar in it had had time to enter the students' blood, the researchers administered a decision-making task that was designed to determine if the participant was using intuition or reason to make up his mind.
The students were asked to think about where they wanted to live in the coming year and given three accommodation options that varied both in size and distance from the university campus. Two of the options were good, but in different ways: one was far from the campus, but very large; the other was close to campus, but smaller. The third option was a decoy, similar to ope of the good options, but obviously not quite as good. ff it was close to campus and small, it was not quite as close as the good close option and slightly smaller, if it was far from campus and large, it was slightly smaller than the good large option and slightly farther away.
Psychologists have known for a long time that having a decoy option in a decision-making task draws people to choose a reasonable option that is similar to the decoy. Dr. Masicampo and Dr. Baumeister suspected that students who had been asked to work hard during the video and then been given a drink without any sugar in it would be more likely to rely on intuition when making this decision than those from the other three groups. And that is what happened; 64% of them were swayed by the decoy. Those who had either not had to exert mental energy during the showing of the video or had been given glucose in their lemonade, used mason in their decision-making task and were less likely to be swayed by the decoy.
It is not clear why intuition is independent of glucose. It could be that humans inherited a default nervous system from other mammals that was similar to intuition, and that could make snap decisions about whether to fight or flee regardless of how much glucose was in the body.
Whatever the reason, the upshot seems to be that thinking is, indeed, hard work. And important decisions should not be made on an empty stomach.

听力原文:Once you have arrived in our country, beware those professional pickpockets. Here's how to protect yourself. Women whose bags are hanging in front of them are tricky for the thieves, as there isn't a blind side. If you want make it even harder, use a bag with handles rather than a strap. For men, one of the best places to keep a wallet is in the back pocket of tight trousers. You'll feel any attempts to move it. Another good place is in the buttoned-up inside pocket of a jacket. There's just no way in. Even better, keep wallets attached to a cord or chain that is fastened to a belt.

Cancer is used generically for more than 100 different diseases, including malignant tumors of different sites such as breast, stomach, colon, lung and mouth.【1】The disease arises principally as a consequence of individual exposure to the substances that cause cancer in what individuals inhale, eat and drink, or are exposed to in their personal or work environment. Personal habits, such as tobacco use, dietary and physical activity patterns—well as occupational and environmental conditions—rather than genetic factors, play the major roles in the development of cancer.
Many of the chronic diseases risk and the diseases themselves overlap. In developed countries, cancer is the second-biggest cause of death after cardiovascular disease (CVD), and epidemiological evidence points to this trend emerging in the less developed world. This is particularly true in countries of "transition" or middle income countries such as in South America and Asia. Already more than half of all cancer cases occur in developing countries.
There are approximately 20 million people living with cancer at the moment; by 2020 there will an estimated 30 million. And the impact is far greater than the number of cases alone would suggest.【2】Regardless of prognosis, the initial diagnosis is of- ten perceived by patients as life-threatening, with over one-third of sufferers experiencing clinical anxiety and depression. Cancer can also be profoundly distressing as well as economically disruptive to patients' families. The clinical care of cancer patients is a costly element in public health budgets.
【3】Dietary factors are estimated to account for approximately 30% of cancers in Western countries, making diet second only to tobacco as a preventable cause of cancer. This proportion is thought to be about 20% in developing countries and is projected to grow. As developing countries become urbanized, patterns of cancer, particularly those most strongly associated with diet and physical activity, tend to shift towards the patterns of economically developed countries. Cancer rates also change as populations move between countries and adopt different dietary patterns.
The relative importance of cancers as a cause of death is increasing. The incidence of lung cancer and cancers of the colon and breast generally increases in parallel with economic development, as stomach cancer declines. Cancer is also strongly associated with social and economic status. Cancer risk factors are highest in groups with the least education. In addition, patients in the lower socioeconomic classes have consistently poorer survival rates than those in higher social class.
In recent years, substantial evidence has pointed to the link from overweight and obesity, to many types of cancer such as breast and kidney.【4】The composition of the diet is also important since fruit and vegetables may have a protective effect by decreasing the risk for some cancer types such as oral and gastric cancer.
Regular physical activity has also been seen to have a protective effect in reducing the risk of breast cancer. High intake of preserved meat or red meat might be associated with increased risk of colorectal cancer. Another aspect of diet clearly related to cancer risk is the high consumption of alcoholic beverages, which convincingly increase the risk of oral cavity, liver and breast cancers.
The wealth of knowledge that already exists about cancer risk factors provides obvious and ample scope for action to reduce the cancer burden of all countries. After tobacco, overweight and obesity seems to be the most important avoidable cause of cancer.
【5】Given that poor nutrition, physical inactivity, obesity tobacco and alcohol are risk factors common to other chronic diseases such as CVD, type 2 diabetes, and respiratory diseases, conducting a cancer prevention program withi
