总结：动词填空题解题步骤：

1.判断用谓语动词形式还是非谓语动词形式。

2.如果是非谓语动词，则根据非谓语动词所充当的句子成分决定填不定式还是分词（根据逻辑主语决定用现在分词还是过去分词）。

3.同一种非谓语动词形式还要注意区分语态与时态。

注意1：

_________ （arrive）at the airport, he started looking for the tour guide. _____________ (make) our plan, we’ll put it into practice.

结论1：非谓语动作与谓语动作只有有明确的先后关系才用完成式，紧接着发生的动作只用一般式。

B. Suffering

C. To suffer

D. Being suffered 注意2：

___________________ （还没完成）his work, he daren't go home. ____________________ (感觉不舒服), he asked a leave.

结论2：非谓语动词的否定要将not放到非谓语动词的最前面。
