The Beginning of Oceanography①Oceanography has been defined as "the application of all sciences to the study of the sea".②Before the nineteenth century, scientists with an interest in the sea were few and far between. 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.③The first time that question "What is at the bottom of the oceanshad 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（起伏形状）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 infonnation on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings（测声）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.④The 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.⑤Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition（考察），which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.7.Even Newton was not willing to go to sea to ______.

What Can Gene Technology BringAmong all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.The greatest thing that gene technology can do is to cure some serious diseases. Doctors at present can almost do nothing with them. Cancer and heart disease are the examples.1.______And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, these two diseases can be cured completely, bringing happiness and more living days to the patients.2______Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary（遗传的）diseases.3______ This is a great trouble for these families. In the past, doctors could do nothing about the hereditary diseases. But gene technology can solve this problem perfectly.4______Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, so these people predict that human babies would soon be cloned. 5______ Of course, the governments must take care to control gene technology.1.

The SleepersThere are times when people are so 1______(tiredness) that they fall asleep almost anywhere. We can see there is a lot of sleeping on the bus or train on the way home from work in the evenings. A man will be reading the newspaper, and seconds later it appears as if he is trying to eat it. Or he will fall asleep on the shoulder of the 2______(strange) sitting next to him. Another place where 3______(planned) short sleep goes on is in the lecture hall where a student will start snoring (打鼾)so 4______(loud) that the professor has to ask another student to shake the sleeper 5______(wake). A more embarrassing (尴尬)situation occurs when a student starts falling into sleep and the 6______(weigh) of the head pushes the arm off the desk, and the 7______(move) carries the rest of the body along. The student wakes up on the floor with no 8______(memorize) of getting there. The 9______(bad) time to fall asleep is when driving. Police reports are full of accidents that occur when people fall into sleep and go off the road. If the drivers are lucky, they are not 10______(serious) hurt. One woman's car, for example, went into the river. She woke up in four feet of water and thought it was raining. When people are really tired, nothing will stop them from falling asleep—no matter where they are.1.
