We have saved as a final set of emotions the two most important emotions pertaining to other people: love and its opposite, hate. Love can be seen everywhere. Yet surprisingly, love has been the subject of less scientific research than other emotions, such as anger and fear. The reason for this may be twofold. First, love is a very complex emotion, difficult to describe and measure. Secondly, unlike many extreme emotions, extreme love is generally not a problem; thus less medical attention has been paid to it.

What is love? This is a complex question and requires a complex answer. Love is an enduring, strong, positive attraction and feeling for another person or thing. But it is more than this. It also involves feelings of caring, protection, excitement, and tenderness. When two people are in love, they feel drawn to one another; they greatly enjoy each other's company; and they may be sexually attracted to one another.

Sometimes it is easier to think in term of different kinds of love: “puppy” love, romantic love, brotherly love, and so forth. Though they differ in some respects, they share one important characteristic: a strong positive feeling toward another.

Our feeling toward other people are often complex. We may love someone and, at the same time, be angry with him. Or we may love someone, even though we are jealous of him. We might even love someone and, at the same time, hate him for some specific reason. Hate is a strong negative emotion toward someone, and is due to anger, jealousy, or some other factor. Like love, hate can be a very strong emotion. It can also be very dangerous. The question is often asked, “Is it bad to hate?” The best answer is probably “sometimes yes and sometimes no.” Usually hate does not help us; it makes us feel unhappy and makes us do things that may hurt others. However, sometimes it may be necessary to hate and hurt someone in order to protect loved ones.

You hear this，“No wonder you are fat．All you ever d0 is eat．”You feel sad．“I skip my breakfast and supper．I run every morning and evening．What else can I do?”

Basically you can do nothing．Your genes，not your life habits，determine your weight and your body constantly tries to maintain it．

Albert Stunkard of the University of Pennsylvania found from experiments that“80 percent of the children of two fat parents become fat，as compared with no more than 14．percent of the children of two parents of normal weight．”

How can obese people become thinner through dieting? Well，dieting can be effective．but the health costs are great．

Jules Hirsch，a research physician at Rockefeller University，did a study of eight fat people．They were．given a liquid formula（配方）providing 600 calories a day．After more than 10 weeks，the subjects lost on average 45 kg．But after leaving the hospital，they all regained the weight．

The results were surprising：by metabolic（新陈代谢的）measurement，fat people who lost large amounts of weight seemed like they were starving．They had psychiatric problems．They dreamed of food or of breaking their diet They were anxious and depressed．Some wanted to kill themselves．They hid food in their rooms．

Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormal state lust like that of starved non．obese people．

Thin people, however，suffer from the opposite．They have to make a great effort to gain weight Ethan Sims of the University of Vermont got prisoners to volunteer to gain weight．In four to six months—they ate as much as they could．They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended，they were back to normal weight and stayed there．

This did not mean that people are completely without hope in controlling their weight．It means that those who tend to be fat will have to constantly battle their genetic inheritance（遗传）if they want to significantly 1ower their weight．

The findings also provide evidence for something scientists thought was true—each person has a comfortable weight range．The range might be as much as 9kg．Someone might weigh 60--69kg without too much effort．But，going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing．the metabolism to push the weight back to the range it seeks．

The story is mainly written to 。

A．point out the relations between our body and mind

B．warn us it’s extremely harmful to reduce or gain our weight

C．tell us that it’s difficult to make a significant change in our weight

D．stress that dieting 1s a recommended way to help you reach your desired weight

Jules Hirsch’s study’found that ．

A．big weight loss could lead to mental problems

B．a person’s weight can be decided by their parents’ weight

C．only dieting cannot produce a desired result in weight reduction

D．big efforts to lose weight may result in a weight much heavier than one’s normal weight

From the text，we know that the body can still feel comfortable

A．when the weight goes up or down by 6 kg

B．when the weight goes up or down by l0 kg

C．when the weight is increased by 20 to 25 percent

D．when the weight is decreased by 20 to 25 percent

What can be inferred from the passage?

A．When it comes to weight，naturalness is the healthiest

B．Weight reduction could be both risky and painful．

C．Seek professional advice when reducing your weight．

D．There’s no hope and no point in controlling your weight．
