The young frog(or tadpole)spends all its life in the water．But the adult frog spends half of its life in the water and half on land．A frog’s back legs are long so that it can jump while on land．But its back feet are webbed--in other words，they have skin between the toes—and this helps the frog to swim．
AnswerⅢ：a tadpole——蝌蚪；webbed——蹼；
PassageⅣ：猜出单词white light，refract，spectrum，primary colors在文中的意思。 Newton discovered that‘white light’(in other words，colorless light from the sun)really consists of a series of colors，which are mixed
a spectrum of seven colors：namely，red，orange，yellow，green，blue，indigo and violet．
Our eyes also recognize colors which are not part of the spectrum．For instance，purple is a mixture of blue and red．
Scientists have found that they can produce almost any color by mixing different amounts of red，green and blue light．(For example，when all three are mixed，they form white．)These are called the primary colours． AnswerⅣ：white colour--白炽光；refract——折射；spectrum——光谱；primary colours——三原色

AnswersⅨ：she-she(thought)；her-Bridget；their-she and Dermot. Passage X：指出下列黑体字所代表的内容。
How do people behave when they are threatened by danger? This is something which has interested psychologists for many years．Recent studies have produced the following findings． Firstly，it seems that men and women often behave differently．In a fire，the latter are likely to warn people and try to save lives，while the former run forward to fight the fire．This was discovered in a study of 500 fire victims．
Secondly，there may be no cowards and no heroes．When they feel threatened，people can react in any one of these ways：they stand still
19 in fear，they try to escape or they risk their lives to save others. But
those who do the last are not always braver than the others．People who
have acted bravely often describe their experience thus：‘If I’d had time to think，I wouldn't have done what I did．’ Danger affects your body in several ways．Here are the signs that you feel threatened． Answer X：

PassageⅪ：阅读短文，找出主题句，并指出主题句是如何被扩展的。
1)The buoyant force of liquid，or how much it pushes upward，depends on the density of the liquid．A body will float if its density is less than that of the 1iquid in which it is immersed；it will sink if its density is greater．Ice is less dense than water，so icebergs float on the surface of the ocean．Steel ships are designed with many spaces filled with air so that their density is less than that of water． 2)What is a black hole?Well,it's difficult to answer this question, since the terms we would normally use to describe a scientific phenomenon are inadequate here．Astronomers and scientists think that a black hole is a region of space(not a thing)into which matter has fallen and from which nothing can escape--not even light．So we can’t see a black hole．A black hole exerts a strong gravitational pull and yet it has no matter．It is only space-or so we think． 3)To discover，how life began，archaeologists study fossils．Fossils are the remains or imprints of plants and animals of long ago that have been preserved in the earth’s crust．The simplest forms of life appear in the lowest or oldest rocks．Although scientists can calculate that the earth is 4．6 billion years old，the oldest rocks that show any trace of 1ife are less than 2 billion years old．Since the oldest forms of 1ife were all sea life，many scientists believe 1ife began in the sea．

There are many types of kinetic and potential energy，including chemical，thermal，mechanical，electrical，and nuclear energy．Chemical energy is potential energy that is stored in gasoline，food，and oil．Just as the watch spring needs to be released to do the work of moving the hand，the energy stored in food molecules needs to be released by enzymes or substances in the body，and the energy stored in gasoline must be released by the spark plug to do its work of propelling the car forward．Thermal energy may be defined as the kinetic energy of molecules. When a substance is heated，the molecules move faster，which causes that substance to feel hot．Mechanical energy is energy related to the movement of objects．Electric energy is energy that is produced by electric charges．Nuclear energy is the energy that is stored in the nuc1eus of certain kinds of atoms，1ike uranium． QuestionⅩⅢ：
1)What does kinetic and potential energy include?
20 1)It includes chemical，thermal，mechanical，electrical，and nuclear
energy.
2)Is thermal energy kinetic energy or potential energy? 2)It is kinetic energy．

Answer I：The power of tornadoes is great and unbelievable． PassageⅡ In one year the world uses as much energy as that contained in 21 billion barrels of oil．And the amount of fuel needed is growing rapidly．The supplies of fossil fuels-coal，oil，and gas-are limited．They may not last for a century．Then what will take their place?
to challenge their authority．Indeed，they behave as if they were hardly a ware that wrong buttons may be pushed，or that a computer may simply malfunction．People should rely on their own internal computers and check the machine when they have the feeling that something has gone wrong． Questioning and routine double-checks must continue to be as much a part of good business as they were in pre—computer days．Maybe each computer should come with the warning：for all the help this computer may provide，it should not be seen as a substitute for fundamental opinion and reasoning skills． Question：It can be inferred from the passage that the author would disapprove of．
Answer XIV：complete dependence on computers for decision——making a／a mentally lazy attitude toward computers．
第二章答题技巧
第一节概括中心思想或段落大意 Passage I
The great power of tornadoes is almost unbelievable．The speed of this whirling funnelshaped wind may be more than 500 miles per hour. It can tear up trees，carry buildings away，and can even lift large trucks off the highway．The tornado is like a giant vacuum sweeper that sucks up anything in its path．Experts believe that the most violent force of a tornado is found inside the funnel，where a vacuum is created because of very low air pressure．When this vacuum moves over a building which is filled with air under normal pressure，the difference between the air pressure inside the building and that outside causes the building to explode．The largest tornado on record had a funnel a mile wide．
For the answer，let's look to the sky．Each day the sun showers the world with several thousand times as much energy as man uses．Here，in a sense，energy is unlimited．The sun's energy is free for the taking．If man could capture even a small part of the sun’S energy at low cost，no one would worry about running out of nonrenewable fuels．
If scientists succeed in making use of the power of the sun，this new energy will have many different uses．The sun’s energy can be used in your own house for heating and cooking.
Then the sun can also be used as a source of fuel for power plants．Solar energy can be used in telephone communication，in space travel，and in farming． Once the sun's energy is captured，the supply of energy will be endless．No wonder those who look to the sky see there great changes in our future way of life．
