Answer 1

本文介绍了电脑的产生、发展以及在我们曰常生活中广泛的使用，针对一些人对将来电脑会控制人类的担忧，作者提出了自己的看法。

1. A one of后要用可数名词的复数形式,根据文章意思，可知答案是A.

2. D要表达第几个世纪，应该用"序数词+ century",而根据常识，计算机是20世纪的产物,A项"21世纪"与实际不符合。

3. B固定搭配not only... but (also) ..,意为"不但……而且……"。

4. A in many ways为一固定用法，表示"在许多方面"。

5. D根据文章大意，可知答案是   D. 表示"给人们带来财富和快乐"。

6. C 因为Eniac是名字，故用called。

7. C根据常识可知老式计算机庞大而笨重，故填largeo

8. D该句意为"自它诞生之日起，它的发展就非常迅速"，since在意思和时态上与主句呼应，为正确选项。

9. C动词短语go through表示"经历"。

10. D 11. A用介词for+宾语表示"为人们做事"，故选入。

12. C know about表示"了解"，侧重于有关某人或某事的具体情况。

13. A learn后面接的是一个宾语从句，而且连接词在从句中做learn的宾语，所以只能用what, 因为that在宾语从句中是纯连词，只能起连接作用，不能做句子成分。

14. D think of表示"想起;认为"；think about表示"考虑"；think out表示"想出"；根据文章含义,答案应是   D.

15. C介词as表示"作为"，为正确选项。
