Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and even cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Some burst with anger, and scream and yell (大叫). But others keep their anger inside. They can not or will not express it. This is called repressing anger.
For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones . They speed the heart rate, raise blood pressure, or sugar into the blood, etc. In general the person feels excited and ready to act.
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, "Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably."

All the housewives who went to the new supermarket had one great ambition: to be the lucky customer who did not have to pay for her shopping.

The cupboards in kitchen were full of things which she did not need. Her husband tried to advise her against buying things but failed. She dreamed of the day when the manager of the supermarket would approach her and say: “Madam, this is Your Lucky Day. Everything in your basket is free.”

She dashed back to the supermarket, got the tea and went towards the cash-desk.

Computer technology has its own special words. One example is the word “mouse”. A computer mouse is not a small animal that lives in buildings or open fields. It is a small object that you move around on a flat surface in front of a computer. The mouse moves the pointer on the computer screen. Computer expert (专家) Douglas Engelbart developed the idea of the mouse in the early 1960s. It was called a mouse because it had a tail at one end. The tail was the wire (电线) that connected it to the computer.
Using a computer takes some training. People who are experts are sometimes called hackers. A hacker is usually a person who writes software programs in a special computer language. But the word “hacker” is also used to describe a person who tries to steal information from computer systems.
Another well known computer word is Google, spelled g-o-o-g-l-e. It is the name of a popular “search engine(引擎)”for the Internet. People use the search engine to find information about almost any subjects on the Internet. People who started the company named it Google because in mathematics, googol, spelled g-o-o-g-o-l, is an extremely large number. It is the number followed by one hundred zeros.
When you “Google” a subject, you can get a large amount of information about it. Some people like to Google their friends or themselves to see how many times their names appear on the Internet. If you Google someone, you might find that person’s name on a blog. A blog is the shortened name for a Weblog. A blog is a personal Web page. It may have stories, opinions , pictures and links(链接) to other Web sites. Some people add information to their blogs every day. People who have blogs are called bloggers.

Very soon the Rabbit noticed Alice, as she went hunting about, and called out to her, “What are you doing out here? Run home this moment, and fetch me a pair of gloves and a fan! Quick, now!”
Alice was so much frightened that she ran off at once in the direction it pointed to. She saw a little house, on the door of which was a plate with the name “W. RABBIT”. She went in and hurried upstairs.
By this time she had found her way into a tidy little room with a table in the window, and on it a fan and two or three pairs of tiny white kid gloves: she took up the fan and a pair of the gloves, and was just going to leave the room, when her eye fell upon a little bottle that stood near the looking-glass. There was no label(标签) this time with the words’ DRINK ME,’ but she opened it and put it to her lips(嘴唇).”I know something interesting is sure to happen,” she said to herself. Before she had drunk half the bottle, she found her head touching the ceiling. She went on growing and very soon had to get down on her knees on the floor. Still she went on growing, and as a last resource, she put one arm out of the window, and one foot up the chimney(烟囱), and said to herself, “Now I can do no more, whatever happens.
