Question

求英语阅读理解的答案

How long, some readers will ask, has the world endured? That is a question which has attracted much attention in the last few years. Gradually the earlier estimates, which varied very widely, have been brought towards agreement. Astronomers and mathematicians who base their computation on the rate of cooling of celestial bodies and on various processes of diffusion and atomic change, give us 2,000 million years as the age of the earth as a body separate from the sun, and about 300 million years as the length of time since life appeared upon it in any abundance. The age of the sun as a star is now supposed to be somewhere in the nature of five billion years. The earth, says Sir James Jeans in his Universe Around Us, will in all probability go on for another billion years and then its equatorial temperature may be sinking to Arctic conditions. Since man has existed as a self-conscious social creature for only 30,000 years or less, this gives him illimitable opportunity for the attainment of knowledge and power. Long before he reaches that limit, he may make himself master of time and space.
1.According to the author, what is the future of man?
A. He will become more confident.
B. He will ultimately have to adapt to arctic conditions.
C. He will eventually die out.
D. He will continue forever.
2.The author of this passage tends to be fairly ____________
A. optimistic
B. pessimistic
C. skeptical
D. indifferent

Answer 1

D
A

Since man has existed as a self-conscious social creature for only 30,000 years or less, this gives him illimitable opportunity for the attainment of knowledge and power. Long before he reaches that limit, he may make himself master of time and space.
因为人类作为有自我意识的社会物种紧有3万或者不到3万年.这便给于人类无限的机会去获取知识和能力.在人类达到极限前,人类或许可以掌握时间和空间.

前文讲地球将会到达另一个冰河时代. 但是文章末却说人类可以掌握时间和空间的能力.也就是说 人类将不会灭亡.

从这里分析 本文作者表现出乐观.

从这里可以看出

A

同理，跟上面里有一样，既然人类能 may make himself master of time and space，显然作者是抱着乐观态度的。
