Thats comforting. But its als

8、o misleading because theres actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against one another, slowly changing each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4. 5

9、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 researchers has an answer. Theyve found new

10、evidence suggesting that Earths 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 billions years ago, lots of asteroids (小行星 ) were hitting Earth, keeping its crust in a hot, melted state. After the hard cr

11、ust formed, much of it sank at various times into the planets 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 Supra-crustal (上地壳 ) Belt. The rocky crust there is be

12、tween 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 volcanic rock. To explain this

13、 structure, the scientists proposed 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 explanation, plus chemical clue

14、s 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. 16 The ground beneath our feet is still. （ A） Right （ B） Wrong （ C） Not mentioned 17 The shape of lands and oceans changed as the plates bumped in to each ot

15、her. （ A） Right （ B） Wrong （ C） Not mentioned 18 As the earth is cooled, it formed the plate. （ A） Right （ B） Wrong （ C） Not mentioned 19 Scientists say the earths crust began shifting 3 billion year ago. （ A） Right （ B） Wrong （ C） Not mentioned 20 It took a long time for the melted earth to become

16、hard again. （ A） Right （ B） Wrong （ C） Not mentioned 21 The formation of Isua supracrustal belt was 8 billion years ago. （ A） Right （ B） Wrong （ C） Not mentioned 22 Isua supracrustal belt is a tourist resort nowadays. （ A） Right （ B） Wrong （ C） Not mentioned 三、 概括大意与完成句子 (第 23-30题，每题 1分，共 8分 ) 下面的短文

24、s accessing health records during patient exams, and managers approving employee requests. A survey by Frost but his employers doctor didnt agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobi

25、le phones. Mobile phone companies a-gree 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 its best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your m

26、obile 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 say they are bad for your health. So for now, its wise not to use your mobile phone too often. 31 People buy cell phones fo

30、o update regular phones （ D） to stop using mobile phones 35 Some People Do Not Taste Salt Like Others Low-salt foods may be harder for some people to like than others, according to a study by a Penn State College of Agricultural Sciences and Food scientist. The research indicates that genetic factor

31、s influence some of the difference in the levels of salt we like to eat. Those conclusions are important because recent, well-publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others, pointed

32、 out John Hayes, assistant professor of food science, who was lead investigator on the study. Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers to lower salt intake through f

33、oods that are enjoyable to eat. This study increases understanding of salt preference and consumption. The research involved 87 carefully screened participants who sampled salty foods such as soup and chips, on multiple occasions, spread out over weeks. Test subjects were 45 men and 42 women, report

34、edly healthy, ranging in age from 20 to 40 years. The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes. They rated the intensity of taste on a commonly used scientific scale, ranging from barely detectable to strongest sensation of

35、any kind. “Most of us like the taste of salt. However, some individuals eat more salt, both because they like the taste of saltiness more, and also because it is needed to block other unpleasant tastes in food, “ said Hayes. “ Supertasters, people who experience tastes more intensely, consume more s

36、alt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more. However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese, Hayes noted“For examp

37、le, cheese is a wonderful blend of dairy flavors from fermented, milk, but also bitter tastes from ripening that are blocked by salt, “ he said. “A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced. Hayes cited research done more than 75 years ago by a chemist nam

38、ed Fox and a geneticist named Blakeslee, showing that individuals differ in their ability to taste certain chemicals. As a result , Hayes explained, we know that a wide range in taste acuity exists, and this variation is as normal as variations in eye and hair color. “Some people, called supertaster

39、s, describe bitter compounds as being extremely bitter, while others, called nontasters, find these same bitter compounds to be tasteless or only weary bitter, “ he said. “Response to bitter compounds is one of many ways to identify biological differences in food preference because supertasting is n

40、ot limited to bitterness. “ 36 In paragraph 2, John Hayes points out that_. （ A） it is good to health to eat food without salt （ B） many people reject low-salt food completely （ C） many people accept low-salt tasteless food reluctantly （ D） food with reduced salt tastes better 37 The fourth paragrap

41、h describes briefly_. （ A） how to select subjects and what to do in the research （ B） how to identify supertasters and nontasters （ C） why to limit the number of subjects to 87 persons （ D） why to select more male subjects than female ones 38 The article argues that supertasters_. （ A） like the tast

42、e of saltiness to block sweet tastes in food （ B） like snack foods as saltiness is their primary flavor （ C） consume less salt because they dont like intensive tastes （ D） like to share salty cheese with nontasters 39 Which of the following applies to supertasters in terms of bitter taste? （ A） Tast

43、e acuity is still a mysterious subject in science. （ B） They like high-salt cheese as it has intense bitter taste. （ C） They prefer high-salt cheese, which tastes less bitter. （ D） They prefer high-salt cheese as it is good to health. 40 What message do the last two paragraphs carry? （ A） Taste acui

44、ty is genetically determined. （ B） Taste acuity is developed over time after birth. （ C） Taste acuity is related to ones eye and hair color. （ D） Taste acuity is still a mysterious subject in science. 40 Calculating Crime When you think about maths, you probably dont think about breaking the law, so

45、lving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals. People who solve crimes look for patterns that might reveal (揭示 ) the identity of the criminal. Its long been believed, for example, that criminals wi

46、ll break the law closer to where they live, simply because its easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely

47、it is that the same criminal did it. But Mike OLeary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminals home base by combining these patterns with a citys layout (布局 ) and histo

48、rical crime records. The records of past crimes contain geographical information and can reveal easy targets that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersect

49、ions are. OLeary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminals patterns change with age. Its been shown, for example, that the younger the criminal, the closer to home the crime. Other computer programmers have worked on similar software, but OLearys uses more maths. The mathematician plans to make
