      We often hear the phrase: “You have 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, 70 people die. That is, 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.

      “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 time, so you should move indoors immediately and stay there until the storm has ended. The most important thing to remember is to seek shelter,”Lopes said.

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

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

      *Do not stand under a tree.

      *Get off bicycle and motorcycles.

      *Crouch down（蹲下）if there is no shelter.

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

    Of the people who are struck by lightning each year in the U.S.A., about ____ people are lucky enough to continue to live.

       A. 400                    B. 330              C. 70                  D. 5

    If you hear the thunder, the most important thing you do is to _____.

       A. find shelter to hide in            B. stand still in the open spaces

       C. stand under a tree               D. stop working in the fields

    Which of the following is NOT true?

       A. If you hear the thunder, you needn’t move indoors right away.

       B. Fewer than 70 people are killed by tornadoes and hurricanes each year in the U.S.A.

    C. People don’t pay as much attention to the danger of lightning as that of floods.

    D. Floods are the first most common cause of deaths during natural disasters in the U.S.A.

    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.

    1.The best title of this passage would be ________.

    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

    D．we can get the by-products of stress by crying

    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.

        A middle-aged stranger visited us late on a dark rainy night when my father was working the night shift (a job for a period during the night).

Then he disappeared, and we started hearing footsteps and creaking boards in the attic(the space or room at the top of a building, under the roof, often used for storing things).

             Modcm inventions have speeded up people’s lives amazingly. Motor-cars cover a bundred miles in little more than an hour. Aireraft cross the world a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every ycar motor-cars are produced which go even faster each new computer boasts（吹嘘）of saving preeious seconds in handling tasks.

Yet before we do so ,we must think of the hard tasks our ancestors faeed;:they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modem machinery has freed peope fre that primitive existcnee.

    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 “light”; 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
