1.) I would appreciate it______you call back this afternoon for the doctor's appointment
A.until B.if C.when D.that
2.)____the poem a second time the meeaning will become clearer to you
A.Your having read B.while reading C.If reading D.when you read
key & reason
第二题选D，但是我还是不是很明白原因~

第一道题目选择B
按照意思就能选择出来了.“如果”
第二题选择D
这个句子后半部分“the meeaning will become clearer to you”是一个完成的句子.
在英文语法中,一个句号中只能有一个完整的句子,除非有连词链接.
很明显“the meeaning will become clearer to you”前面并没有连词.那么“____the poem a second time”这部分必然是个从句.
再看“the meeaning will become clearer to you”的主语是“the meeaning ”.那如果从句省略主语,则应该与主句的主语保持一致,也应该是“the meeaning”.
很显然B和C省略了主语,但是read是人发出的,而不是“the meeaning ”.首先淘汰掉.
其次A选项用了一个现在完成时（这里用了省略系动词的形式,但是还是现在完成时）,明显主语是将来时,两者时态不能兼用.
最后只剩下了D.
读一下句子,意思语法完整,时态正确.OK就选择D了.
