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.

Having one of those days or weeks — when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster — often within a day or two.

Walk it off

Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.

Tune it out

Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.

Give yourself a pep talk

Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper; the pessimistic (悲观的) messages you’ve been giving yourself and then give optimistic answers. ("I still don’t have a job. "vs" I have two interviews next week.")

Reduce your stress

Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing (想象), all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no options(选择权) By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.

Avoid things that won’t improve your mood

TV may not help much: You need to increase your energy level and stimulate your mind something — that the TV show "Neighbors" won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta, produce a calming effect in people who have a desire for them.

We learn from the text that it might help rid us of a bad mood ________.

A. to do nothing about it

B. to take a long walk on the beach

C. to do some exercises with light music

D. to talk it to neighbours

Why is it suggested that you close your eyes and picture the beach?

A. It is not complicated to do so.

B. It is an area to be easily controlled.

C. It helps beat a bad mood.              

D. It brings us a new technique.

TV may not improve your mood because ________.

A. it sometimes shows what happens around you

B. it keeps you stay unmoved

C. it reminds you of eating and drinking

D. it produces a calming effect

This text most probably appears in ________.

A. a book on physical exercises            B. a doctor’s handbook

C. a notice                                    D. a magazine

Some futurologists have assumed that the vast upsurge(剧增)of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse(反面)of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to putting off marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy comes to life, the number of marriages also rises.

The increase in divorce rates follows to the increase in women working outside the home. Yet, it may be wrong to jump to any simple cause-and-effect conclusions. The impact of a wife’s work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible(似是而非的). Tensions grounded in financial problems often play a key role in ending a marriage. By raising a family’s standard of living, a working wife may strengthen her family’s financial and emotional stability.

Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union.

Also, a major part of women’s inequality in marriage has been due to the fact that, in most cases, men have remained the main breadwinners. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities.

The word “portend” (Line 2, Para.1) is closest in meaning to“_____”.

    A. defy   B. signal   C. suffer from   D. result from

It is said in the passage that when the economy slides_____.

    A. men would choose working women as their marriage partners

    A. they are more likely to dominate their marriage partners

    B. their husbands are expected to do more housework

    D. they tend to suspect their husbands? loyalty to their marriage

Which of the following statements can best summarize the authors view in the passage?

    A. The stability of marriage and the divorce rate may reflect the economic situation of the country.

    B. Even when economically independent, most women have to struggle for real equality in marriage.

    C. In order to secure their marriage women should work outside the home and remain independent

    D. The impact of the growing female workforce on marriage varies from case to case.

Are Societies Ageing Too Fast?

       An ageing society is one in which the population of people over the age of 60 is increasing.The global population at present is about 6 billion with 1 person in every 10 aged 60 or above._.This will mean that for the first time in human history the population of older persons will be larger than the population of children! What are the causes of this population change?

       _.And another is that birthrates have dropped as people, especially women, are educated.Measures to slow population growth like China’s one-child policy, have also contributed to lowered birthrates.The increase in the aged population is not just an interesting trend, however; it also has severe implications for the future of global economies.

       People traditionally retire at 65 and live on government pensions._.Another concern is that as medical expenses increase with age, the demands of the growing aged population will eventually cause medical systems to face bankruptcy(破产).

       ___.They suggest that because people are living longer, they ought to work longer, while governments need to establish a sound social security system.They also suggest that individuals start saving as soon as possible to ensure a financially secure retirement.People should also develop good health habits in their youth to ensure an active and productive old age.__.By finding cures for diseases like Alzheimer’s and cancer, medical bills and the need for care would be drastically reduced.

       Finally, an important step to ensure a bright future for all is to do away with negative stereotypes that see valuable members of society only as pensioners or patients.It’s high time we stopped seeing ageing as a disease and started playing our parts in securing the future of our ageing societies.

A. Due to ageing problem, cities are facing more challenges.

B. Experts insist that steps should be taken now to prepare for the future.

C. As people grow older, a huge financial burden will be placed on the government.

D. Biomedical research is another tool we can use to deal with the problems of ageing societies.

E. One reason is that dramatic health advances have added 20 years to the average life-expectancy.

F. The United Nations projects that by 2050, it will be 1 in every 5.

G. As is known to all, good habits lead to good health.

The bar-tailed godwit (斑尾鷸)has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.

The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.

One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.

Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

1.For the flight from Alaska to New Zealand, the bar-tailed godwit__________

A.doesn’t need to stop to eat

B.is afraid of hot weather

C.seems very tired at last

D.should fly less than 7,000 meters

2.The main reason why the bar-tailed godwit can break the record is that it ______.

A.eats little food every hour

B.has a special body shape

C.stores much water in its body

D.has very light body weight

3.The last paragraph tells us that _________.

A.researchers have understood the bird very well

B.the bird has a very good sense of direction

C.there are still many who doubt the bird’s ability

D.the bird has an inner compass

 

 

A.The great impact and progress in genetic engineering

         B.Worries about privacy protection

         C.Worries about medical use of genetic engineering

         D.Genetic knowledge helps to predict diseases

         E.Genetic knowledge may not be properly used

         AB.The application of genetic engineering in the medical fields

 

1.__________

Current research into the human gene system is helping us understand why people have predispositions(易患某病倾向)to certain diseases.Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer.Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be.Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings.

2.__________

The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases.Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes (中风). But with the research that is now being conducted, we may find cures to many more diseases.In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.

3.__________

Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against.Another problem is that many people do not want to discover their weakness.What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?

4.__________

Many people believe that history has not always shown human decision-making to be bright when it comes to ethical(道德的)choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society.

5..__________

One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious.
