问题补充:
—Tomorrow my birthday, I’d like you and Jane to come.
-- I’m not sure if she free.
A. will be; is going to
B. is going to; is
C. will be; is
D. is; will be
答案:
A. will be; is going to
B. is going to; is
C. will be; is
D. is; will be
解析:考察时态和从句。第一句明天是我的生日,在一个陈述句事实的句子,不是将来时。第二空的if意为:是否。引导的是宾语从句。从句中用将来时。句意:—明天是我的生日。我想你和Jane来参加。—我不敢肯定他她是否有空。故D正确。
