麻烦各位,给补充说明一下吧! 万分感谢!!

7C:因为前一句是现在进行时~所以后面那句也是~
8D:be going to do将来时~be doing有时也可以用现在进行时表示将来时~但不是所有单词都可以~start就不可以
9B:就是上面说的那种情况,用现在进行时表示将来时~leave是典型代表之一
10C:be to do表示已经计划好的,将要去做~be going to do 主要指应对当前情况将要发生的,没有计划的。will be就是一种将要发生的状态,没什么特别 呃
11B:用一般现在时表示常常做的事情~
12A:自从那以后就一直持续的动作,到现在可能任然再进行,所以不用D~since than是完成时的一种标志了~一般遇到都会用完成时的~
