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 reason 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.
16 How did the speaker’s friends respond to his change of interest?
17 What is one of the reasons for the speaker to switch his interest to underwater exploration?

选项
A、They both attract scientists’ attention.
B、They both can be quite challenging.
C、They are both thought-provoking.
D、They both lead to surprising findings.
答案
B
解析
短文提到,出人意料的是,海洋与太空有许多共同之处,对于人类来说,海洋和太空同样不友好,如果要在其中生存,必须借助器械的帮助。B“它们都挺有挑战性的”是对原文的概括,故选B。
