If you have to miss one meal day(or if you want to do so),which meal will cause you fewest health problems if you don't eat it? lf they have to make a decision of this type,most people(especially dieters or very busy people)will choose to skip breakfast.
However,many experts in the field of health consider breakfast(the meal which “breaks”your“fast”which started the night before)to be the most important meal of the day.If we eat a good breakfast,they say,we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humor.Nevertheless,many people skip breakfast or substitute a donut and a cup of coffee for a well-balanced meal.What hap-pens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people.Participants included both males and females who ranged in age from 12 to 83.During the experiment,these people were given a variety of breakfasts,and sometimes,they had to skip breakfast completely.Special tests,including blood tests and endurance tests,were set up to analyze how well the participants'bodies functioned when they had eaten a certain kind of breakfast.
The results showed that if a person eats an adequate breakfast,he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast.This fact appears to be especially true if a person's work involves mental activity.The study showed that if schoolchildren eat fruit,eggs,bread,and milk before going to school,they will learn more quickly and will be able to concentrate on their lesson for a longer period of time than if their breakfast diet is inadequate.
The study also showed that,contrary to what many people believe,if you skip break-fast,you will not lose weight.This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing.So remember,if you are on a diet,skipping breakfast will not help you.You will probably lose more weight if you reduce your other meals.

What do those countries in the world have in common? People are killing each other or driving others out of their families. Why is this hap pening? Very simple, really: in each h of these places, and elsewhere in the world, one group of people believes that another group is different from them and dangerous to them. It has been thus throughout history. How different are humans from each other?
We come in different colors: red, blank, white, yellow and brown; we have a variety of political systems, social systems, religious views(宗教信仰) or none at all; we are different in mind, have different educational systems, different socio-economic classes. We speak different languages, and have different customs and dresses.
If we were to break each of these further, we would have quite a long list of qualities and characteristics that make humans appear to be different from each other. I say they appear to be different , because most of what I have listed stands for what we see or hear, not what is true of human. Man is man everywhere, which is only because where he lives. when he lives there, with whom he lives there, and all have effect on how he lives, that is, what he believes, what he wears, his customs, his gods, his language and so on. These are man-made fact that each group develops over time living together, facing the same problems, needing and desiring the same things. They are his culture. The truth is that we are much more the same than different. If you wear one type of clothing and I wear another, we both wear some kind of clothing. Our culture demands it. If you speak one language and I another, we both speak so that others will understand us. We must communicate with each other. Nothing is gained by giving too many differences, but much lost . If we understood our differences as the ones of culture, then we could make our world more peaceful.
Difference doesn't mean better or worse, right or wrong . It means only that differences have been made by society. Differences produce variety of thought, feeling and action, and that can be very helpful to work out human problems peacefully.

查看习题详情和答案>>You must have been troubled by when to say “I love you” because it is one of the greatest puzzles in our life.
What if you say it first and your partner doesn’t love you back? Or if they do say it but you don’t feel they mean it? Being the first to declare your love can be nerve racking(紧张)and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn’t it pay to hold back, play it cool and wait until the other half has shown their hand fast?
A really good relationship should be about “being fair and being equal,” says psychologist Sidney Crown. “But love is seldom equal.” All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. “That feeling of ‘I’ve always loved you more’ may be subverted(颠覆,破坏) for a time, but it never goes away completely and it often emerges in squabbling(大声争吵).” In love, at least, the silent, withholding type is not always the most powerful. “The strongest one in a relationship is often the person who feels confident enough to talk about their feelings,” says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. “The one with the upper hand is often the person who takes the initiative. In fact, the person who says ‘I love you’ first may also be the one who says ‘I’ m bored with you’ first.” Hall believes that much depends on how “I love you” is said and the motivation of the person saying it. “Is it said when they’re drunk? Is it said before their partner files off on holiday, and what it really means is ‘Please don’ t be unfaithful to me’ ?” By saying ‘I love you’, they are really saying ‘Do you love me?’ If so, wouldn’t it just be more honest to say that. Collins agrees that intention is everything. “It’s not what is said, but how it’s said. What it comes down to is the sincerity of the speaker.”

查看习题详情和答案>>The government-run command post in Tunis is staffed around the clock by military personnel, meteorologists and civilians. On the wall are maps, crisscrossed with brightly colors arrows that painstakingly track the fearsome path of the enemy.
What kind of invader gives rise to such high-level monitoring? Not man, not beast, but the lowly desert locust(蝗虫). In recent months, billions of the 3-inch-long winged warriors have descended on Algeria, Libya, Morocco and Tunisia, blackening the
sky and eating up crops and vegetation. The insect invasion, the worst in 30 years, is already creating great destruction in the Middle East and is now treating southern Europe. The current crisis began in late 1985 near the Red Sea. Unusually rainy weather moistened the sands of the Sudan, making them ideal seedbed for the locust, which lays its eggs in the earth. The insect onslaught threatens to create yet another African famine. Each locust can eat its weight (not quite a tenth of an ounce) in vegetation every 24 hours. A good-size swarm of 50 billion insects eats up 100,000 tons of grass, trees and crops in a single night.
All ﹩150 million may be needed this year. The U.S. has provided two spraying planes and about 50,000 gal. of pesticide. The European Community has donated ﹩3.8 million in aid and the Soviet Union, Canada, Japan and China have provided chemical-spraying aircraft to help wipe out the pests. But relief efforts are hampered by the relative mildness of approved pesticides, which quickly lose their deadly punch and require frequent replications. The most effective locust killer dieldrin has been linked to cancer and is banned by many Western countries and some of the affected African nations. More than 5 million acres have been dusted with locust-killing chemicals; another 5 million will be treated by the end of June.
On May 30, representatives of Tunisia, Algeria, Libya, Morocco and Mauritania will meet in Algiers to discuss tactics to wipe out the ravenous swarms. The move is an important step, but whatever plan is devised, the locust plague promised to get worse before the insects can be brought under control.

One of my difficulties is to spell English. English words are too difficult to spell correctly. I always need a 1 which I can keep 2 me when writing. When I think 3 a word that I am not sure I can spell, I look it 4 in the dictionary. But what 5 words I think I really can spell? Some of these words are the 6 that I always spell wrongly!
What I need 7 a book that contains (包含) all the words spell 8 . Where can I find it? Properly I shall have to write it 9 ! Of course, I need a book which I can rely on (依靠). If I can't rely on it, 10 is the use of it? Also, it must be a book to carry 11 , so it must be small 12 to put in my pocket.
An Englishman 13 I knew to be a university lecturer once told me that 14 the most educated Englishman 15 spell every English word correctly! If he hears a new word which he has never heard before, he cannot be 16 how to spell it! I was so surprised that I wouldn't believe it, but he said, 17 , there are nearly 18 a million words in English, and nobody knows all of them, and secondly, English is not spelled phonetically (根据语音地). What he said 19 me very happy! If an English lecturer cannot spell 20 English words correctly, how can I?
