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. 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 those73 people die. That means more people are 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 to 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 from 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 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.
The popular opinion about being struck by lightening is that .
A. there is a greater chance for being killed by lightening than any other natural disaster
B. it is the most dangerous among all the natural disasters
C. the chance for a person to be struck by lightening is very small
D. it is impossible for people to be killed by lightening
The average death rate of being struck by lightening in US is about .
A.18% B.50% C.30% D.73%
Among all the safety tips, the most important one is that when you hear thunder in the open air, .
A. just stand by your bicycles and motorcycles
B. quickly find a place to go inside
C. count ten seconds between a thunder and a lightening
D. don’t have a hair drier in your hand
According to the passage, which of the following is TRUE?
A. There are more people killed by tornadoes and hurricanes than by lightening in US each year.
B. There are on average 5 persons killed by lightening in Nepal each day.

When I was small and my grandmother died I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that crying does so, too.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to be helpful. Study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don’t even know we’re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don’t fight it. It’s a natural — and healthy — emotional response (反应).
59. Why didn’t the author cry when her grandmother died?
A. Because her father did not want her to feel too sad.
B. Because she did not love her grandmother.
C. Because she was too shy to cry at that time.
D. The author doesn’t give the explanation.
60. It can be inferred from the text that ______.
A. there are two ways to keep healthy
B. crying does more good to health than laughing
C. crying and laughing play the same roles
D. emotional health has a close relationship to physical health
61. According to the author, which of the following statements is TRUE?
A. Crying is the best way to get help from others.
B. Fighting back tears may cause some health problems.
C. We will never know our deep feelings unless we cry.
D. We must cry if we want to reduce pressure.
62. What might be the most suitable title for the text?
A. Power of Tears B. How to Keep Healthy
C. Why Do We Cry D. A New Scientific Discovery
Doctors say anger can be an extremely damaging emotion(情感), unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell(咆哮).But other people keep their anger inside. They can not or will not express it. This is called repressing (抑制) 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(荷尔蒙).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(强烈地) 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(解决办法) 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.”?
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. They said that laughter is much healthier than anger.?

Every pet owner loves his pet. There is no argument here.
But when we asked our readers whether they would clone(克隆) their beloved animals, the answers were split almost down the middle. Of the 228 readers who answered it, 108 would clone, 111 would not and nine weighed each side without offering an opinion.
Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and final sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure.
Most of the respondents (被调查的人) who liked the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope a clone could never truly recreate a pet, many simply didn’t wish to go against the natural law of life and death.
Both sides expressed equal love for their animals. More than a few respondents owned “the best dog/cat in the world”. They thought of their pets as their “best friend”, “a member of the family,” “the light of my life.” They told moving stories of pets’ heroism(英勇精神), cleverness and selfless devotion.
“People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of Goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
But would cloning reduce the blow? This question seemed to be at the heart of this problem.
71. So far as the cloning of pets is concerned, a recent survey shows that, of all pet owners, __________.
A. a lot more of them are for it
B. a lot more of them are against it
C. very few of them are willing to tell their opinions
D. about half of them are for it and the other half against it
72. While talking about the respondents from the readers, the underlined expression “final sadness of owning a pet” refers to ___________.
A. the death of one’s pet
B. the high cost of owning a pet
C. the troubles one has to deal with in keeping a pet
D. the dangers involved in the cloning of a pet
73. In spite of(尽管) their differences on the problem of cloning, it seems that ________.
A. all pet owners try to go against the natural law of life and death
B. all pet owners love their pets very much
C. people who support cloning love their pets more
D. people who dislike cloning love their pets more
74. From what Gary Kowalski says, we can know that he _________.
A. has never thought about the problem of cloning
B. is going to write another book on pets
C. support the idea of cloning pets
D. is all against the cloning of pets
75. What is the key question at the heart of the problem of cloning pets?
A. Can cloning make one suffers less pain when a pet dies?
B. Can pet owners afford the cost of cloning?
C. Does cloning go against the law of nature?
D. Can cloning really produce an exact copy of one’s pet?
