One reason Americans eat so many calories is that we tend to eat large portions(分量). Studies find that hamburgers and fries are generally offered in serving sizes two to five times larger than the appropriate meal size. Researchers find we usually clean our plates no matter how high they're piled, even if we already feel satisfied. See the suggestions below to further master the fine art of sizing up（估量） your snacks and suppers.

Extremely large portions are one possible reason Americans continue getting fatter even as the percentage of our total calories from fat has gone down in recent years. Fortunately, portions are relatively simple to control because it's easier to count cookies than calories or grams of fat.

Pre-picture portions. Use familiar objects to picture how much you should eat of a food before you pick up your fork or spoon. For example, a half cup of low-fat granola is about the size of your fist. A half cup of low-fat ice cream equals half an orange.

Use a smaller dish. This tip might sound ridiculous, but it works. First and most obvious is that you can't put as much food on, say, a salad plate. But psychologically, you're just not as prone to eat as heartily and quickly if your plate will be empty in 45 seconds.

Have raw vegetables at every meal. Raw cucumbers, tomatoes, carrots, and peppers have few calories and lots of nutrients. A plate of them in the middle of the table almost always gets eaten up, cutting down appetite for the more calorie-dense meat.

Start your meal with soup. Studies show that a bowl of soup at the start of the meal reduces overall meal consumption, since they are lowest in calories and highest in nutrients.

Manage your fork. After every bite of food, put your fork down. Don't pick it up until you have thoroughly chewed and swallowed the previous bite. The goal is both to slow down your eating and to eat less. Remember: Your body needs 20 minutes of digestion before it sends signals to your brain that you are no longer hungry.

Modern society cannot well do without the contribution that women can make in the professions and other kinds of work. There is a serious shortage of nurses and teachers, to mention only two of the occupations followed by women. It is a waste to give years of training at public expense only to have the qualified teacher or nurse marry after a year or two and be lost forever to her profession. The training, it is true, will help her in her duties as a mother, but if she continued to work, her service would be more widely useful. Many factories and shops, too, are largely staffed by women, many of them married. While here the question of training is not so important, industry and trade would be seriously short of staff if married women did not work.
We can see then that there are good reasons for regarding it as desirable that married women should have some occupation outside the home. However, there are serious objections. Schools do not keep children occupied the whole day and school holidays are long. The mother’s working day will almost certainly end well after the school day and her holiday will not begin at the same time as her children’s. There will be therefore a period when children are not taken care of unless a substitute for the mother can be found, or unless it becomes more generally possible for women to work part-time. There seem to be some grounds for believing that there is more bad behavior among the children of working mothers than among those of mothers who stay at home, but more evidence is required before we can be certain of this. What we can be certain of, however, is that many more will continue to do so.
【小题1】According to the writer, women nurses and teachers ought to carry on their occupation after marriage because______.

A．they are not allowed to give up their jobs

【小题2】According to the writer, one possible way for the children of working mothers to be attended to is that________.

A．schools keep children occupied the whole day

B．their mothers change their occupation

C．their mothers do not work full time

D．their mothers should stay at home

【小题3】The clause “unless a substitute for the mother can be found” means_______.

A．if someone takes over the mother’s occupation

B．if no mother works all day

C．if no one takes care of the children for the mother

D．if someone takes care of the children for the mother

【小题4】The writer believes that bad behavior among the children of mothers who do not work is _________ among the children of working mothers.

    In the college-admissions wars, we parents are the true fighters. We’re pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. I’ve twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids’ college background as a prize demonstrating how well we’ve raised them. But we can’t acknowledge that our obsession(痴迷) is more about us than them. So we’ve created various justifications（辩解）that turn out to be half-truths, prejudices or myths. It actually doesn’t matter much whether Aaron and Nicole go to Stanford.

We have a full-developed panic; we worry that there won’t be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. What causes the hysteria(歇斯底里) is the belief that scarce elite（精英）degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All seems right but mostly wrong. We haven’t found any convincing evidence that selectivity or prestige matters. Selective schools don’t systematically employ better instructional approaches than less selective schools. On two measures—professors’ feedback and the number of essay exams selective schools do slightly worse.

By some studies, selective schools do enhance（提高） their graduates’ lifetime earnings. The gain is reckoned at 2-4% for every 100-point increase in a school’s average SAT scores. But even this advantage is probably a statistical fluke(偶然). A well-known study examined students who got into highly selective schools and then went elsewhere. They earned just as much as graduates from higher-status schools.

Kids count more than their colleges. Getting into Yale may signify intelligence, talent and ambition. But it’s not the only indicator and, surprisingly, its significance is declining. The reason: so many similar people go elsewhere. Getting into college is not life’s only competition. In the next competition—the job market and graduate school—the results may change. Princeton economist Alan Krueger studied admissions to one top Ph.D. program. High scores on the GRE helped explain who got in; degrees of famous universities didn’t.

So, parents, take it easy（lighten up）. The stakes (利害关系) have been vastly exaggerated. Up to a point, we can rationalize our pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be destructive. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction. They may have been so conditioned to being on top that anything less disappoints.

“Most experiences of absent-mindedness ,forgetting where you left something or wondering why you just entered a room , are caused by a simple lack of attention, ” says Schacter. “You’re supposed to remember something, but you haven’t encoded（编码） it deeply.”
　Encoding, Schacter explains, is a special way of paying attention to an event that has a major impression on recalling it later. Failure to encode properly can create troublesome situations. If you　put your mobile phone in a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in your cupboard. “ Your memory itself isn’t failing you, ” says Schacter, “Rather, you didn’t give your memory system the information it needed.”  http://wx.jtyjy.com/
　Lack of interest can also lead to absent -mindedness. “A man who can recite sports statistics from 30 years ago, ” says Zelinski, “ may not remember to drop a letter in the mailbox.”Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory depends on just that.
　　“Visual cues（ 视觉提示 ）can help prevent absent--mindedness, ”says Schacter, “But be sure the cue is clear and available. ”If you want to remember to take a medicine with lunch, put the pill bottle on the kitchen table—don’t leave it in the medicine box and write yourself a note that you keep in a pocket.
　　Another common experience of absent - mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time, ”says Zelinski. “The best thing to do is to return to where you were before entering the room, and you’ll likely remember.”
【小题1】The writer of the passage thinks that encoding properly is very important because ________.

A．it enables us to recall something from our memory

B．it slows down the process of losing our memory

C．it helps us understand our memory system better

D．it helps us to get back to where we were

【小题2】One possible reason why women have a little better memories than men is that________.

A．they rely more on the environment

B．they have a wider range of interests

C．they have an unusual power of focusing their attention

D．they are more interested in what’s happening around them

【小题3】Why can a note in the pocket hardly serve as a reminder? ________.

A．It will easily get lost

B．It is out of your sight

C．It’s not clear enough for you to read

D．It might get mixed up with other things

【小题4】From the last paragraph we can learn that________.

A．repetition might help improve our memory

B．memory depends to a certain extent on the environment

C．we’d better return to where we were if we forget things

D．we should think about something else while doing one thing

【小题5】The passage is mainly about ________.

A．the memory system of persons

B．a way of encoding and recalling

C．the causes of absent-mindedness

D．the impression of the environment on memory

Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?

The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis, by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.

A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.

The attempt to discover the explanation of this phenomenon in the antithesis of “facts” and “theories” or “facts” and “ideas”—in the neglect among the ancients of the former, and their too exclusive attention to the latter—proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories.

Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.
