试题分析：通过本文考查了学生对一些英语语法的理解和应用。如固定搭配，形容词副词的区别，名词的用法等。

1.when 考查连词。这里的意思是：当他在实验室工作的时候意外的发现了X光线。when表示“当……时候”。

2.2】clearly 考查副词。这里用副词修饰动词，表示“清楚地”。

3.3】and 考查连词。这里用and并列连接X-ray和report。

4.4】over 考查短语。all over the world意为“全世界”，为固定短语。

5.5】discovery 考查名词。这里需要用名词，discover为动词，需改为名词discovery。

6.6】to look 考查动词短语。use sth to do sth表示“用……做……”，为固定短语。

7.7】Using 考查动名词。这里需要用动名词作主语。

8.8】unknown 考查助动词。这里表示“未知的放射性”，故用形容词unknown，表示“未知的”。

9.9】them 考查宾格。这里需用宾格作宾语，they为主格，需改为them。

10.10】made 考查时态。本文时态为一般过去时，所以这里需用过去式。
