D．They were afraid he wasn't fully prepared.
听力原文： When my interest shifted from space to the sea, I never expected it would cause such confusion among my friends, yet I can understand their feelings. As I have been writing and talking about space flight for the best part of 20 years, a sudden switch of interest to the depth of the sea does seem peculiar. To explain, I'd like to share my reasons behind this unusual change of mind. The first excuse I give is an economic one. Underwater exploration is so much cheaper than space flight. The first round-trip ticket to the moon is going to cost at least 10 billion dollars if you include research and development. By the end of this century, the cost will be down to a few million. On the other hand, the diving suit and a set of basic tools needed for skin-diving can be bought for 20 dollars. My second argument is more philosophical. The ocean, surprisingly enough, has many things in common with space. In their different ways, both sea and space are equally hostile. If we wish to survive in either for any length of time, we need to have mechanical aids. The diving suit helped the design of the space suit. The feelings and the emotions of a man beneath the sea will be much like those of a man beyond the atmosphere.

Male sea horses have a fold of skin on their bellies that forms a pocket, called a brood pouch. During the breeding season, the sea horse's pouch swells to receive eggs. A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return every day to check on her mate and the eggs, but she doesn't stay long, nor does she take part in the birth.
It takes from five to six weeks for the eggs in the male's pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult from him to swim, so the male often uses his tall to grasp a piece of sea grass. Firmly, gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change Iris color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs.
The eggs hatch inside the male's pouch. When the babies begin moving around, the mate sea horse knows it's time for them to be born. He grabs a sea grass stem with his tail and begins rocking, bending his body back and forth, this causes the opening to enlarge until wide enough for the first baby sea horse to shoot out. the father sea horse continues rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out.
Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tiered when it's over.
Soon after giving birth to one brood, the male will approach his mat and show her his empty pouch. This tells her he is ready to receive eggs again.
What part does the female sea horse play in having babies？
A．Receive eggs.
B．Laying eggs.
C．Hatching eggs.
D．Protecting eggs.
Oceanography
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．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(大陆间的) 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(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(测水深) 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 with living creatures, 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.
第 41 题 We can infer from the passage that the telegraph cable was built mainly for____.
A．oceanographic studies
B．military purposes
C．business considerations
D．investigating the depths of the oceans
