8、These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. “This never happened before,“ say the older citizens of Kiribati. What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being bur
9、ned, pollutants (污染物 ) are released; these pollutants trap heat in the earths atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川 ) and polar (极地的 ) ice caps. If the trend continues, scientists say, many countries will suffer. Bangladesh, for exam
10、ple, might lose one-fifth of its land. The coral (珊瑚 ) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate - they would be swallowed by the sea. The loss of these coral islands would be everyones loss. Coral formations are home to more specie
11、s than any other place on earth. The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence.

Most young children ask a lot of questions and you should give careful scientific answers. Dont only give facts, but try to give explanations as well. 2 Science is not just k
17、nowledge; it is a way of thinking, a method of finding out about the world. We see something. We try to explain it, and we test our idea by setting up an experiment. One day you come home and find the plant on the table has fallen over. You think it might be the wind from the open window or the cat,
18、 so you close the window, but leave the cat in and see what happens (you can also try leaving the window open and shutting the cat out). Of course, you remember there may be a third explanation. 3 Ask your child to get a piece of string, some salt, a glass of water and an ice cube (冰块 ). Tell her to
19、 put the ice in the water, and then put one end of the string on the ice, leaving the other end over the side of the glass. Put a little salt on the ice. Wait a minute, and then pull the string; it should be attached to the ice. Ask the child: “What has happened?“ 4 Probably she wont know. Ask her w
20、hether fresh water or salt water freezes into ice first. If you live near the sea and have a cold winter, she should know fresh water freezes first as she will have seen that happen. Show her how to test the idea by half-filling two paper cups with water, adding salt to one. Then put them in the ice
21、box and check every three minutes. Write the results in a table. The conclusion will be that salt changes the behaviour of water. Thinking about the string, we see the salt turned some of the ice into water. Then the salt went away into the water and the ice froze again leaving the string attached.
22、5 Then you can ask, “Will water with salt boil at the same temperature as water without salt?“ She can think, tell you her idea and you can test it in the kitchen. (take care because of the heat) 23 A What exactly is science? B How do you find an explanation? C What topics do you need? D How do you
23、answer your childs questions? E Where does your child study science? F How do you set up the experiment on salt and water? 23 Paragraph 1 _. 24 Paragraph 2 _. 25 Paragraph 3 _. 26 Paragraph 4 _. 27 A the icebox B the ice C scientific answers D the experiment E the world F Water 27 When your child as

25、o AIDS Now Most people say that the USA is making progress in fighting AIDS, but they dont know theres no cure and strongly disagree that “the AIDS epidemic is over,“ a new survey finds. The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worded that public c
26、oncern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths. “While people are very optimistic about the advances, theyre still realistic about the fact that there is no cure.“ says Sophia Chang, director of HIV programs at the foundation. The Kaiser
27、survey, like a recent USA TODAY Gallup Poll, does find that the number of people ranking A1DS as the countrys top health problem has fallen. In the Kaiser Poll, 38% say its the top concern, down from 44% in a 1996 poll; in the Gallup Poll, 29% say AIDS is No.1, down from 41% in 1992 and 67% in 1987.
28、 Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November: 52% say the country is making progress against AIDS, up from 32% in 1995. 51% say the government spends too little on AIDS. 86% correctly say
29、AIDS drugs can now lengthen lives; an equal number correctly say that the drugs are not cures.67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell. Daniel Zingale, director of AIDS Action Council, says, “Im encouraged that the American people are g

34、gs Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter,
35、 in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments. Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A pl
36、ant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the suns energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptation
37、s that only certain kinds of plants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the abil
38、ity to remain completely still when an enemy is near. Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded
39、 mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to
40、 readapt to the new conditions. 36 Some plants and animals develop superior characteristics so that they may _. （ A） help others of their kind get food, shelter and other things needed （ B） survive even in extremely severe conditions （ C） become better adapted to the environments San others of their
41、 kind （ D） result in the evolution and production of more intelligent organisms 37 In the first paragraph, the word “environments“ could best be replaced by_. （ A） contexts （ B） surroundings （ C） neighbors （ D） enemies 38 It can be inferred from this passage that the feathers of a bird care colored
42、_. （ A） to frightened its enemies （ B） to attract its enemies （ C） to adjust its body heat （ D） to match its environment 39 Which of the following is not directly mentioned? （ A） A living thing may adapt in its structure. （ B） An organism may adapt in its function. （ C） A living creature may adapt i
43、n its genetic makeup. （ D） A living organism may adapt in its sleeping habit. 40 The author cites the behavior of warm-blooded mammals in order to illustrate which of the following? （ A） A living thing may have the ability to create an environment of its own. （ B） A living creature may have the abil
44、ity to remain still when an enemy is near. （ C） A living creature may have the ability to make food from its inorganic chemicals. （ D） A living creature may have the ability to change the color of its skin. 41 Inspecting a Used Car The scariest part of buying a used car is not being completely sure
45、of what condition its in. A car thats been in a major accident is always a bigger risk, but sellers often try to hide this information. Andrew Bleakley, evaluator-inspector, runs a mobile vehicle inspection service in Montreal. For about $ 80 he will perform a full, unbiased inspection on a used veh
46、icle. In his 10 years as a professional inspector, Bleakley has seen a lot. He warns. “Watch out for dealer demonstration vehicles which are used, not new. They may have been in a collision.“ He adds that it is not uncommon in Ontario and Quebec especially for unscrupulous sellers to roll back the o
47、dometer or to even disengage it. Bleakiey has special tools to check for this. Bleakley always recommends hiring all independent technician to inspect the condition of a. used car before you buy it. The problem is finding someone qualified to do the inspection. Which he says generally doesnt mean ju
48、st any mechanic. A thorough mechanical inspection includes checking the compression, all major systems, including the engine, electrical and charging systems, transmission and drive line, fluids, brakes, suspension, and steering. Essential, too, is all inspection of the cars body and finally a road
49、test. There are, however, a few things everyone can do before buying a used car: Do a visual check of the car. Look at the right rear door hinges. If they are very worn, or the door doesnt close well, the car may have been used as a taxi. Holes in the roof could mean the car was used for deliveries. Check for oil leaks on the pavement. Note that leaks are not necessarily a significant problem it depends on the cause. Dont as
