单选题Oceanography has been defined as "The application of all sciences to the study of the sea." Before 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 travellers 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 (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 information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings (测探) 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(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.

单选题With the current mood of global uncertainty and an economic recession, people are likely to suffer from increased stress, depression and anxiety. These psychological symptoms, in a new twist to the old saying of "mind over matter", can lead to actual physical problems. The mind and the body are integrated system. It's like a web. If one part is disturbed, it will directly, or indirectly, affect another part. Hence, psychological and emotional reactions will trigger physical responses. When a person feels a threat to his well-being, the brain reacts by releasing chemicals. For example, the adrenal gland in the brain may release adrenaline(肾上腺素) which prepares the body to respond to physical threats. The brain's neuro-chemistry programs a person to react in one of the classic ways: fight, flight or fright. Are you sleeping well? Are you eating well? Are you working or studying well? Any mental health problem would affect these three areas of behavior. Some people deal with stress and anxiety by turning to religion, others by talking to friends and family. But there are other options. Exercise is a good outlet. Play a game. Go jogging. You will be concentrating on doing something. There is a target to be achieved and will occupy your mind. Go Karaoke singing and dancing with friends. The worst thing to do is to sit at home and think.
