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

A．hotels and restaurants B．large enterprise groups C．local councils and officials D．commercial property developers

Rather than taking the final then, what they did was to find Professor Aldric after the final and explain to him why they missed the final. They told him that they went up to UVA for the weekend, and had planned to come back in time to study，but they had a flat tire (爆胎）on the way back and didn’t have a spare and couldn’t get help for a long time and so were late getting back to campus. Aldric thought this over and then agreed that they could make up the final on the following day. The two guys were overjoyed and relieved. So, they studied that night and went in the next day at the time that Aldric had told them. He placed them in separate rooms and handed each of them a test booklet and told them to begin. They looked at the first problem, which was something simple about free radical formation and was worth 5 points. “Cool，" they thought, “this is going to be easy. " They did that problem and then turned the page. They were unprepared, however, for what they saw on the next page. It said: (95 points) Which tire was flat？ The two students decided to visit their friends at the weekend beacause_______ A.they didn’t want to take the exam B.they were invited by their friends C.they were not worried about the exam at all D.they forget the arrangement of the final exam They didn’t return as planned because_______.A.they got lost on their way back B.they slept beyond the time to come back C.their car broke down on their way back D.they couldn’t get help when they were in difficulty How did the Professor arrange the make-up exam？A.He made the exam booklet very long.
