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(掩蓋) the very real dangers of lightning.

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

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.

A. there’s a greater chance for being killed by lightening than any other natural disaster

We don’t plan to cry, but it just happens. In fact when we feel sad or angry, a good cry is almost impossible to resist. But if you didn’t know what crying was, you’d have to wonder why some strong feelings started water streaming from people’s eyes and why they seemed to feel better afterwards.

Now a US researcher had found there may be more in crying than we think. William H. Frey II, author of “Crying: The Mystery of Tears,” believes it may really be one of the body’s clever self-repair mechanisms. Crying may be a way of getting rid of the by-products of stress, he says.

He has found that tears contain some chemicals which can cause stress. One of these is the hormone prolactin (激素), which is set free when one is feeling stressed. Since women have more of this than men, that might explain why they usually cry more, he suggests.

Unsurprisingly, Dr Frey’s study seemed to prove that most people feel better after a good cry. And sex has nothing to do with it ––– the result was true for women and men. So, next time you feel like bursting into tears, go ahead. If Dr Frey is right, you’ll be doing yourself a favour.

A．Why Do We Cry                        B．Crying and Tears.

A．crying is one of our habits

B．we can’t control it

C．crying is one of the body’s self-repair mechanisms

3.According to the passage, men seem less likely to cry than women because_______.

A．their bodies contain less hormone prolactin

B．their tears contain more chemicals

C．they are not so full of feelings as women

D．the chemicals in their tears can’t cause stress

4.The author advised us________.

A．to plan to cry very often

B．not to cry any more

C．to go outdoors without hesitation

D．to cry as we want to

5.Which of the following is NOT true according to the passage?

A．Good cries can make most people feel better

B．Only women can feel better after crying.

C．It is easy to understand that people feel better after a good cry.

D．Crying is sometimes impossible to resist.

An earthquake is caused by a sudden slip on a fault, or fracture, in the earth's surface. The tectonic plates on the surface are always slowly moving, but they get stuck at their edges because of friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and create the shaking we feel.

An earthquake's degree is a measured value of its size and is the same no matter where you are, or how strong or weak the shaking was in different locations. An earthquake's intensity is a measure of the shaking it creates, and varies with location.

A degree of 8 or higher defines a “great” earthquake; 7 to 7.9 is considered “major”; 6 to 6.9 is “strong”;5 to 5.9 is “moderate”; 4 to 4.9 is “l(fā)ight”; 3 to 3.9 is "minor"; and less than 3 is “micro.”

Experts have said that a million people died in earthquakes in the 20th century ­and that this century might see 10 times as many deaths, with as many as a million killed in a single quake. That is, unless major efforts are made to fortify the world’s growing cities, which are expected to be homes to billions of added residents.

Even though the rate of earthquakes over time seems to be more or less unchanging, the world's population explosion means that more people are moving into quake zones, which are often near coasts. The result, the experts say, is the prospect of continuing trauma.

“It is inevitable,” Klaus H. Jacob, an earthquake expert at Lamont-Doherty, the earth sciences research center of Columbia University, said at the end of the last century. “More and more people, and more and more buildings, are  at stake  . As the world gets more populous and richer, allowing a more built-up environment, higher buildings and all the infrastructure that supports our civilization, communications and the like, the risk goes up.”

  63. We can feel the earthquake because               

    A. the plates are always moving.     

    B. the stress overcomes the friction.

    C. the plates get stuck.  

    D. the waves in which energy is released travel through the earth’s crust.

   64. a degree of 8.2 is thought              

   A. a  “moderate” earthquake.         B. a “major” earthquake .

   C. a “strong” earthquake.             D. a “great” earthquake.

  65.  Experts have said that                

   A. a billion people died in earthquakes in the 20th century.

   B. ten times as many deaths will be seen by this century.

   C. a million people will be killed in a single earthquake this century.

   D. if we don’t take measures, something worse may happen.

   66. The underlined expression probably means           .

    A. endangered       B. strong         C. safe        D. weak
