A. will go, is fine
B. goes, is fine
C. will go, is going to be fine
D. goes, will be fine
答案：
(答案→)A. will go, is fine
B. goes, is fine
C. will go, is going to be fine
D. goes, will be fine
解析：本题的含义是你知道弗兰克这个星期天如果不下雨是否同我们去剧院，第二个if表示条件，遇到将来用一般现在时，故填is fine，第一个if引导的是宾语从句，遇到将来要用将来，故第一个空填will go，故本题选A。
