1.All countries can take part if their athletes reach the standard ______ to the game.
A. admitted
B. to be admitted
C. being admitted
D. admitting

2.They had a new kind of program,which ______ before the competition.
A.had just been developed
B.was just developed
C.had just been developing
D.was just developing

求答案+合适的解释 谢谢!

A过去分词做定语。显然只有A符合
A前面有个had,而 develop显然应在had之前。故再退一步,用过去完成时。

C B

两题都选A。

1. B (好奇怪的句子)
固定形式,to be admitted 作定语修饰 standard
eg. the work to be done, the book to be read

2. A
前半句是过去时,后半句是说过去的过去发生的事,所以用过去完成时。
