It is a terrible illustration of man &39; s weakness to nature ,and the tsunami(海 啸) that struck the Japanese coast in March, 2011 has illustrated the difficulty of fighting against natural disasters, even for a prosperous nation.
Totally preventing tsunami-damage is impossible. But there is much that can be done to minimize damage and loss of life. Measures that can be taken include designing solid buildings, and developing early-waming systems, public education programs and evacuation(疏散) strategies. Moreover, the approach of a tsunami is possibly picked up by the sensors of complicated international waming systems. Countries can use radio and television broadcasts as well as loudspeaker networks to warn the public.
But an early waming system depends on how far the tsunami strikes, if it&39; s close by, the warning system is not going to be very effective. When people are faced with an unstoppable force like a tsunami the massive waves created by events like underwater earthquakes, the best course of action for them is to get inland and to the higher ground as quickly as possible.
51. The first paragraph tells us that________
A.man can easily defeat the nature
B.tsunamis take place only in Japan
C.man’ s ability to cope with natural disasters is limited
D.the tsunami-damage in Japan is not so terrible
To prevent tsunami-damage, the following measures can be taken EXCEPT________A.designing firm buildings
B.developing early-warning systems
C.developing evacuation strategies
D.keeping the public unaware of the seriousness of tsunamis
When a tsunami happens, the best course of action for people is to________A.listen to radio and television broadcasts for information
B.get inland and to the higer ground as quickly as possible
C.stay where they are
D.rely on the warning systems
According to the passage , which of the folloiwing can cause a tsunami ？A.Storms
B.Massive waves
C.Underwater earthquakes
D.Floods
Which of the following statements is correct according to che passage？A.The total prevention of tsunamis is possible
B.Rich countries are less affected by tsunamis than poor countries
C.Approaching tsunamis can possibly be picked up by sensors
D.An early warning system is effective when a tsunami is close by

W: Stem cell research sounds pretty impressive,I'll admit.But just what is it？
M: Well,a stem cell is a special type of cell.It is a general cell that.when it divides.Call become any specific type of cell.
W: You mean,a stem cell can become a heart cell？Or a brain cell or a kidney cell？
M: That's about it.Stem cells are a part of the body's maintenance and repair system.When they divide, they can become any cell type.
W: I guess there would be some tremendous medical advantages in that sort of research.
M: You've said a mouthful.Recently,scientists were able to help a man who lost a jawbone from cancer.They recreated bone material for his jaw from stem cells.What it means is that since the new bone was created out of the person's own cells,there was no problem with rejection because the DNA was the same.
W: I bet the person was delighted.Why would anyone oppose that sort of research？It would seem to have endless potential to benefit the human race.
M: I agree,but there are people who think we should not interfere with nature and mainipulate"what is not natural".
W: It is easier to hold such a narrow view if you're not in a position to need the benefits of the research.If you're missing a jawbone because of cancer,you probably support the research.
What is the man's attitude toward the stem cell research？
A．Supportive.
B．Opposed.
C．Pessimistic.
D．Neutral.

The Inner Clock That Rules Our Lives
Guess what time it is---without looking at your watch! The chances are you will be right within half an hour. Or try waking up at a particular time--without an alarm clock. You'll probably be able to do that, too.
Just about everyone can do these things, with a little practice, because the human body has its own built-in clocks.
There is a complex series of interacting rhythms in nearly everything the human body does. It sleeps to a rhythm, eats to one, and even shows a rhythm in the electrical waves produced by the brain.
Three main rhythmic cycles affect body time: the daily rhythms of the revolving earth; the monthly orbit of the moon around the earth; and the yearly journey of the earth around the sun,
A Perfect Time Sense
Not only mankind is affected by these great natural fides. All animals and plants feel them; too. Sometimes a body clock can keep accurate time to the precise minute, as in the case of the bean aphid (蚜虫), which can either lay eggs or produce live young, according to natural time that when the daylight lasts longer than 14 minutes, live offspring are born to take full advantage of the extra warmth. If the day is shorter, the aphid lays eggs to hatch at a later time.
Man's time sense is both mental and physiological. He feels hungry every three to four hours. His brain cells show two-to-three-hour cycles of activity. Even dreams run in cycles. During dreaming, the eyes, even under closed eyelids, show rapid scanning movements. Measurements of this movement, during "rapid eye movement", or "REM", permit accurate timing of periods of dreaming. Based on this, man appears to dream in cycles of about 90 minutes.
Circadian Rhythm
Man's natural rhythm of life is balanced between the length of the 24-hour solar day and the lunar day, which is 50 minutes longer. For this reason it is called the circadian (昼夜的) rhythm. Under normal conditions the circadian rhythm is constantly influenced by the rising and setting of the sun. But people isolated from outside stimuli--such as prisoners kept constantly in cells without natural light--revert automatically to a longer natural cycle.
The circadian pattern seems to be controlled partly by the hypothalamus--an area in the base of the brain close to the pituitary (垂体) gland. The hypothalamus can regulate pituitary secretions, and thus, the activity of a number of other endocrine (内分泌) gland. Effects on the cortex of the adrenal (肾上腺) gland, and changes in release of an adrenal hormone called cortisol (皮质醇), appear to be especially important in certain kinds of rhythms. These mechanisms are highly adaptable.
Most humans do have contact with natural stimuli, and their slightly shorter version of the circadian rhythm is vitally important to them. Temperature, blood pressure, pulse, breathing, and hormone activity all rise and fall in time with the world's slow spin.
A Cycle for Illness
Similarly, ability, temper, and even resistance to infection are controlled by the circadian clock. This may be why some epileptics have seizures only at certain times of the day or why pregnant women get morning sickness.
Experiments have shown that mice injected with pneumonia germs at 4 a.m. survive better than those injected at any other time of day. This could be important to humans. If vulnerability to disease is rhythmic, then response to vaccination is likely to be rhythmic, too.
Circadian rhythms account for the difference between "owls", people who are wide awake at night and stay up late, and "larks", who rise early, do their best work in the morning, and go to bed early.
Lark and Owl Patterns
Both the lark people and the owl people have quite distinct rhythms, probably because of differences in the rhythm of
