7、ound feels solid beneath our feet. That“s comforting. But it“s also misleading because there“s actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scienti

8、sts know that Earth formed about 4.5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust(地壳), eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researcher

9、s has an answer. They“ve found new evidence suggesting that Earth“s crust started shifting at least 3.8 billion years ago. The new estimate is 1.3 billion years earlier than previous ones. Not long before 3.8 billion years ago, lots of asteroids (小行星) were hitting Earth, keeping its crust in a hot,

10、melted state. After the hard crust formed, much of it sank at various times into the planet“s hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地壳) bel

11、t. The rocky crust there is between 3.7 and 3.8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of vo

12、lcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock, called magma(岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explana

13、tion, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beginning around 3.8 billion years ago.（分数：7.00）(1).The ground beneath our feet is indeed still.（分数：1.00）A.RightB.WrongC.Not mentioned(2).The shape of lands and oceans are sl

15、It took a long time for the melted crust to become hard.（分数：1.00）A.RightB.WrongC.Not mentioned(6).The formation of the Isua supracrustal belt is thought to have started about 3.8 billion years ago.（分数：1.00）A.RightB.WrongC.Not mentioned(7).The Isua supracrustal belt is now a popular holiday resort.（分

In many countries, cell phones are very popular with young people. They find that the phones are more than a means of

26、communicationhaving a mobile phone shows that they are cool and connected. The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there

27、 has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health. On the other hand, why do some medical studies show changes in the brain cells of some people who us

28、e mobile phones? Signs of change in the tissues of the brain and head can be detected with modern scanning (扫描) equipment. In one ease, a traveling salesman had to retire at a young age because of serious memory loss. He couldn“t remember even simple tasks. He would often forget the name of his own

29、son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer“s doctor didn“t agree. What is it that makes mobile phones potentially harmful? The answer is radiation. Hig

30、h-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about. As the discussion about their safety continues, it appears that it“s best to use mobile phones less often. Us

31、e your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it“s wis

32、e not to use your mobile phone too often.（分数：15.00）(1).People buy cell phones for the following reasons EXCEPT that _.（分数：3.00）A.they“re popularB.they“re cheapC.they“re usefulD.they“re convenient(2).The world “ detected “ in paragraph 3 could be best replaced by _.（分数：3.00）A.curedB.removedC.discover

No school I have taught in has ever ignored spelling or con

36、sidered it unimportant as a basic skill. There are, however, vastly different ideas about how to teach it, or how much priority(优先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely and confidently in writing wi

37、thout holding him back with the complexities of spelling? If spelling becomes the only focal point of his teacher“s interest, clearly a bright child will be likely to “play safe“. He will tend to write only words within his spelling range, choosing to avoid adventurous language. That“s why teachers

38、often encourage the early use of dictionaries and pay attention to content rather than technical ability. I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: “This work is terrible! There are far too many spelling errors and your writing is illegible

39、 (难以辨认的).“ It may have been a sharp criticism of the pupil“s technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay, which contained some beautiful expressions of the child“s deep feelings. The teacher was not wrong to draw attention to the

40、errors, but if his priorities had centered on the child“s ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.（分数：15.00）(1).Teachers differ in their opinions about _.（分数：3.00）A.the difficulties in teaching spellingB.the role

41、 of spelling in general language developmentC.the complexities of the basic writing skillsD.the necessity of teaching spelling(2).The expression“ play safe“ probably means _.（分数：3.00）A.to write carefullyB.to do as teachers sayC.to use dictionaries frequentlyD.to avoid using words one is not sure of(

Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it

45、is the least efficient, unhealthiest and most environmentally damaging fossil fuel. Natural gas reserves could plug some of the gap from oil, hut reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. We could fas

46、t reach an energy crisis. We need to rapidly develop sustainable solutions to fuel our future. Less-polluting renewable energy sources offer a more practical long-term energy solution. They may benefit the world“s poor too. “Renewable“ refers to the fact that these resources are not used faster than

47、 they can be replaced. The Chinese and Romans used watermills over 2,000 years ago. But the first hydroelectric dam was built in England in 1870. Hydroelectric power is now the most common form of renewable energy, supplying around 20% of world electricity. China“s Three Gorges Dam, which has just b

48、een completed, is the largest ever. At five times the size of the US“s Hoover Dam, its 26 turbines will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China“s entire electricity demand. Surprisingly, some argue that hydroelectric dams significantly contribute g

49、reenhouse gases. In 2003, the first commercial power station to harness tidal currents in the open sea opened in Norway. It is designed like windmill, but others take the form of turbines. As prices fall, wind power has become the fastest growing type of electricity generationquadrupling worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world“s entire energy needs. Wind farms come in onshore and offshore forms. Th
