IV. 注意问题
1. 语气问题：
所谓肯定语气就是从句本身不缺少任何句子成分，只需要连接词that 就可以表达一个完整的意思；而所谓的疑问语气则是指主句本身包含有疑问的、或不清楚、不肯定的、或还没有决定等意向，或者是从句还需要某个带疑问语气的连接词来充当某个句子成分才能表达一个完整的意义或概念，这时不能用that来引导从句。（一般说来，ever类词和that 都是表达肯定语气的选择。）
Who stole the necklace will be found out soon. Whoever breaks the law will be punished.
I don’t know whether he’ll come to our help. That Japan lies east of China is known to us all. That fashion differs from country to country may reflect the cultural differences from one aspect. That people spend so much money on their pets surpris us a lot.
2. 语序问题：凡是从句都应该用陈述的语序。
马来西亚双威大学The manager asked what was the matter // the trouble. The manager asked what was wrong. The teacher asked who had broken the window. (_上面三句话的引导词都充当主语，语序不变。) The teacher asked why Tom hadn’t turned up.
3.主谓一致：一般说来，单个的主语从句做主语，主句的谓语动词用单数。
