Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood.

Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily. Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and

machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.?

1. The stone chip is thought to be the most important tool because it ______.

A. was one of the first tools

B. developed human capabilities?

C. led to the invention of machines

D. was crucial to the development of mankind

2. At the end of the passage the author seems to suggest that life in future is ______.

A. disastrous

B. unpredictable

C. exciting

D. colorful

1. D) 這是一道細節題。根據文章第二段尾句

“Some scientists say that it was the key to the success of mankind”

可知“stone chip”對於人類的發展起到了非常重要的`作用，這與D正好相符。

2. B) 在文章最後一段中作者説人類在過去的幾百萬年時間 裏一直使用“stone chip”，人類社會發生的變化很小。而我們使用“silicon chips”才不過幾年，生活卻發生了巨大的變化。 於是作者發出了疑問：“二十年後的生活會是什麼樣子的呢?”， “ 二百萬年後的世界又會是什麼樣子呢?”， 表明將來的生活無法預料，這與選項B相符
