　The way people hold to the belief that a fun - filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.

　　As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment （预担的义务）, self - improvement.

　　Ask a bachelor（单身汉） why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.

　　Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

　　Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

According to the author, a bachelor resists marriage chiefly because ________ .

　　A. he is reluctant to take on family responsiblilities

　　B. he believes that life will be more cheerful if he remains single

　　C. he finds more fun in dating than in marriage

　　D. he fears it will put an end to all his fun adventure and excitement

　Raising children, in the author’s opinion is ________ .

　　A. a moral duty

　　B. a thankless job

　　C. a rewarding task

　　D. a source of inevitable pain

From the last paragraph, we learn that envy sometimes stems from ________ .

　　A. hatred　　　　　　　　　　　　B. misunderstanding

　　C. prejudice　　　　　　　　　　　D. ignorance

To understand what true happiness is one must ________ .

　　A. have as much fun as possible during one’s lifetime

　　B. make every effort to liberate oneself from pain

　　C. put up with pain under all circumstances

　　D. be able to distinguish happiness from fun

We often hear the phrase: "You've a greater chance of being struck by lightning." It is used to describe something that hasn't got much chance of happening. However, the common saying undermines(掩盖) the very real dangers of lightning.

Last Friday, at least 5 people were killed by lightning in Nepal(尼泊尔).

Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year, and of those, 73 people die. There are more people killed by lightning than by tornadoes and hurricanes.

Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters.

So to raise awareness, the US has made June 22-28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms.

"If you hear thunder, you are in danger of lightning," said Rocky Lopes, a disaster educator at the American Red Cross.

"Thunder means that lightning is close enough to hit you at any minute, so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek a hiding place," Lopes said.

Summer is the high time for lightning storms, so when lightning strikes across the sky, remember these safety tips:

Stop working, fishing, swimming or playing in open fields.

If you can count less than ten seconds between a thunder and a lightning flash, take cover inside the nearest building.

Do not stand under a tree.

Get off bicycles or motorcycles.

Crouch down(蹲下)if there is no hiding place.

Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers.
