导致了演出被取消。put out灭火put off延期，故第一个空用put off；第二个空，表示正在进行，且cancel与其逻辑主语"the show"之间是被动关系，故用现在分词的被动式，故选C项。

考点考查动词短语及非谓语动词:

7.With your help, there is no doubt our plan is meant for will work out successfully.

A. what; that B. whether; that

C. that; whether D. that; what

【答案】D

【解析】

【详解】考查名词性从句。句意：在你的帮助下，毫无疑问，我们的计划意味着这个问题将被成功解决。there is no doubt后是一个同位语从句，doubt用在否定句中，从句用that引导；______ our plan is meant for是同位语从句中的主语从句，缺少for的宾语，用what引导。故选D.

【点睛】There is no doubt that ...是一个固定句式，意思是"毫无疑问......"，that引导的是同位语从句。doubt的用法还有have no doubt that ..., there is some/much/little doubt ...等。doubt还可以后接宾语从句。如：

There is no doubt that he is an honest man.

I have no doubt that you will succeed.

注意：不管是在同位语从句中还是在宾语从句中，在否定句中，doubt后面接that从句，而在肯定句中，通常接whether引导的从句。如：

There is no doubt that he will agree with us.

There is some doubt whether he will come to this activity tomorrow.

8. to the gift was a note on which he expressed his gratitude for our reception during his stay here.

A. Being attached B. Attaching

C. Attached D. having attached

【答案】C

【解析】
