Answer 1

1.D 看到for就是典型的现在完成时代表，然后因为left是点动词，所以不能用于完成时。
2.B since表示现在完成时
3.C already意思是已经，句子中又有for，要用现在完成时
4.C he has made much progress这句话运用了现在完成时，再根据句意，果断选C。
这几道题都是现在完成时的题型，同学好好学，因为很重要。

Answer 4

第一个选D。这是一个现在完成时，标志性的词组是“for a month”
第二个选B。这同样是现在完成时，标志性“since”
第三个选C。这同样是现在完成时，标志性“for two years”
第四个选C。这是由“since”引导的现在完成时，表示“自从”。
综合几个题，楼主你可以看一下现在完成时的相关语法，加强一下。
