7、ound 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.Scientists

8、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 researchers has an

9、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 hot, molte

10、n 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 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 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

12、 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, plus chemical cl

13、ues 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 mentioned17 The shape of lands and oceans are slowly changed with the movements of plate

27、 many people may suffer health problems from the use of mobile phones. In England, there 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

28、hand, why do some medical studies show changes in the brain cells of some people who use mobile phones? Signs of change in the issues of the brain and head can be detected with modern scanning (扫描) equipment. In one case, a traveling salesman had to retire at a young age because of serious memory lo

29、ss. He couldnt remember even simple tasks. He would often forget the name of his own 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 employers doctor didnt agree.Wha

30、t is it that makes mobile phones potentially harmful? The answer is radiation. High-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 thei

31、r 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 mobile phone only when you really need it.

Th

36、e 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 content in food have left many people struggling to accept fare that simply does not tast

37、e 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 companies are working together on ways to help consumers lower salt intake through foo

38、ds 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, reportedl

39、y 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 any

40、 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. Supertasters, people who experience tastes more tensely, consume more salt than nontast

41、ers 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 example, cheese is a

42、 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 pronounced.Hayes cited research done more than 75 years ago by a chemist named Fox and a

43、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.36 John Hayes pointed out that _.A food with le
