问题 By the time you get back, great changes ______ in this area.
选项 A、will take place
B、are taking place
C、will have taken place
D、are to take place
答案 C
解析 本题考查将来完成时的用法。句中有by the time表示到某一时间已完成某动作，且由you get back可知，应选用将来完成时，故选项C为正确答案。再如：By the time you come back next week，we will have finished the job．(下星期你回来时，我们就已经把工作做完了。)
[避错指南] 选项A为一般将来时，B为现在进行时，D用一般将来时，在此都不符合句子的时间状语的要求。
