7、, the ground feels solid beneath our feet. Thats comforting. But its also misleading because theres 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. Sc
8、ientists 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, eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researche
9、rs has an answer. Theyve found new evidence suggesting that Earths crust (地壳) 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 pummeling Earth, keeping its crust in a
10、 hot, molten state. After the hard crust formed, much of it sank at various times into the planets hot insides. There, it melted before returning to the surface as lava. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrus
11、tal(上地壳) belt. 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 look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of vol
12、canic 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 area cooled, forming what we see today. That explanation, p
13、lus 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. 16 The ground beneath our feet is indeed still. A Right B Wrong C Not mentioned 17 The shape of lands and oceans are slowly changed with the
14、movements of plates. A Right B Wrong C Not mentioned 18 Earth cooled down shortly after it was formed. A Right B Wrong C Not mentioned 19 Scientists once estimated that Earths crust started shifting three billion years ago. A Right B Wrong C Not mentioned 20.It took a long time for the melted crust
15、to become hard. A Right B Wrong C Not mentioned 21.The formation of the Isua supracrustal belt is thought to have started about 3.8 billion years ago. A Right B Wrong C Not mentioned 22. The lsua supracrustal belt is now a popular holiday resort. A Right B Wrong C Not mentioned 第3部分：概括大意与完成句子(第2330题

29、man had to retire at a young age because of serious memory loss. He couldnt remember even simple tasks. He would often forget the name of his own son.

31、mount is too small to worry about. As the discussion about their safety continues, it appears that its best to use mobile phones less often.

36、ording to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat. Those conclusions are important because recent, well-publicized (大力宣传的) efforts to reduce the salt con
37、tent 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 out John Hayes, 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
38、 companies are working together on ways to help consumers lower salt intake through foods 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 mult
39、iple occasions, spread out over weeks. Test subjects were 45 men and 42 women, reportedly 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 comm
40、only used scientific scale, ranging from barely detectable to strongest sensation of 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 because it is needed to block other unpleasant tastes in food, said Hayes
41、. Supertasters, people who experience tastes more tensely, consume more salt 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 bloc
42、k unpleasant bitter tastes in foods such as cheese, Hayes noted. For example, cheese is a wonderful blend of dairy flavors from fermented (发酵的), 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
43、pronounced. Hayes cited research done more than 75 years ago by a chemist named 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
44、normal as variations in eye and hair color. 36 John Hayes pointed out that _. A food with less salt tastes better. B many people never eat low-salt food. C many people make efforts to accept low-salt food. D it is good to health to eat food without salt. 37 The fourth paragraph briefly describes_? A
45、 why the number of subjects was limited to 87. B why more male subjects were chosen than female ones. C how salty foods were made and distributed to the subjects in the research. D how the subjects were selected and what they were asked to do. 38 It is true that _. A nontasters like to share salty c
46、heese with supertasters. B supertasters like the taste of saltiness to block sweet tastes in food. C nontasters consume more salt because they like intense tastes. D supertasters like snack foods more as they contain higher levels of saltiness. 39 Supertasters prefer high-salt cheese because _. A it is good to health. B it tastes less bitter. C it is rich in nutrition. D it has intense bitter tastes. 40 It can be inferred from the last paragraph that taste acuity is _. A genetically determined. B identified with certain chemicals. C developed over time after birth. D related to o
