Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work. For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question "what is at the bottom of the oceans？" Had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured. It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea. The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a fivevolume report, the last volume being published in 1895. The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on ______. A．an academic aspect B．a military aspect C．a business aspect D．an international aspect

They could see there was something wrong with both watches. They observed them for several hours before speaking to each other. They both silently found the German watch was losing 60 minutes and the Japanese are doubled that. The scientists with the Japanese watch then slowly raised his head and said, “Both watch are out of work, but my watch is right more often than yours, so it’s better.” The scientist with the German watch went home without saying a word. (1) The two scientists were quarrelling at the beginning of the story, because_______. A.the Japanese watch was better B.the German watch was better C.each of them thought his own watch was better than the other’s D.both the watches were wrong (2) They did an experiment because they_______. A.wanted to know whose watch was better B.liked their lab C.wanted to repair their watches D.had a basin of water in their lab (3) After they did the experiment, they found_______. A.both their watches were good B.neither of their watches could tell the correct time C.there was something wrong with the German watch D.there was something wrong with the Japanese watch (4) After putting the Japanese watch in water for 20 minutes, two scientists found_______. A.it was a good watch B.it went forward C.it went faster than the German one D.it went backwards 120 minutes (5) How about the German watch at last？ A.It went more correctly than before. B.It stopped working. C.It went as well as the Japanese one. D.It was better that the Japanese one.

“Breast-feeding not only has short-term benefits, but also breast-feeding has long-term benefits, ” says Bernardo Lessa Horta of the Federal University of Pelotas in Brazil, who led the study being published in The Lancet Global Health. Doctors have long known that breast-feeding can be good for a baby’s health. This is especially true in poor countries, where water can be contaminated. For instance, a baby given formula in developing countries is 14 times more likely to die in the first six months than one who’s breast-fed. In the U.S., some research has suggested that breast-feeding may raise a baby’s IQ(智商)by a few points. But a recent study with siblings(兄弟姐妹)found little advantage to breast-feeding. Horta says these previous studies didn’t follow children into adulthood to see if breast-feeding had long-term effects. So Horta analyzed data collected from 3,493 volunteers he and his colleagues have been following since birth. They are now in their 30s. First, the researchers gave the subjects IQ tests. Those who were breast-fed for 12 months or more had IQ test scores that were 3.76 points higher than those who were breast-fed for less than one month, the team found. When Horta and his colleagues looked at how much education the subjects had gotten and how much money they were making, they also found a clear difference: Those who were breast-fed the longest stayed in school for about an extra year and had monthly salaries that were about a third higher. 1. From the passage, we learn that Horta {A; B; C}. A. is from Brazil B. conducts his research in the U.S. C. has 30 researchers on his team 2. Which of the following about those who were breast-fed is NOT mentioned？{A; B; C} A. They stayed longer in school B. They were happier C. They were smarter 3. Which of the following is TRUE？{A; B; C} A. Doctors don’t understand the benefits of breast-feeding. B. Horta is concerned with water contamination in poor countries. C. Horta’s research project lasted about 30 years 4. The word contaminated in Paragraph 3 is closest in meaning to {A; B; C}. A. finished B. interested C. polluted 5. Which of the following is an appropriate title for this passage？{A; B; C} A. Researchers Have Pointed Out the Disadvantages of Breast-feeding B. Researchers Have Found Out the Shortcomings of Formula C. Breast-feeding Improves Chances of Success
