解答：

1、第一個句子是含有if 引導的條件狀語從句的複合句,前半句Frank _____ a film 是主句,後半句if he's free next Saturday爲從句,主句用一般將來時,從句則用一般現在時.後半句用的是一般現在時,is free,所以主句用一般將來時,will see.故 選D.
2、第二句和前一個句子 其實屬於同類句子,前半句will go 一般將來時,後半句則要用一般現在時,而且是否定句,故選B.
3、for 目的,with則表示伴隨情況.選A.
4、根據句子意思,需要填入一個「直到」盡頭.所以選擇B.
5、第五句這是徵求對方意見,「我可以問你一個問題嗎?」,英語正確的回答是1、肯定回答 Yes,please.即允許對方任何時候提問題；2、否定回答,Sorry,you mustn't.拒絕回答問題.
