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?
18 In what way does the speaker think diving is similar to space travel?
19 What is the speaker’s purpose in giving this talk?
选项
A、To show how simple the mechanical aids for diving can be.
B、To provide reasons for his changeable character.
C、To explore the philosophical issues of space travel.
D、To explain why he took up underwater exploration.
答案
D
解析
主旨题。在听完整篇短文及回答完以上三个问题之后,可以发现大部分篇幅都是用来解释作者为什么对underwater exploration(水下探险)发生了兴趣。所以选D。
