1.有道选择：she-------well at school but that changed when she became friends with a different group of girls Adid Bhad done C had been doing
我选的b 正确答案选c 这个没有持续下去,为什么要用过完进行时?过完和过完进行时的区别呢?2.有一例句：I HAVE BEEN READING FOR THE PAST TWO WEEKS.这句用了现完进行时,我觉得是不是用现完也可以?因为已经完成了
能讲下具体出现since、for该怎样区分用现完还是现完进行时?

进行时（现在/过去进行时）强调动作开始后,一直延续,到说话时还在进行中；完成式表示结束了,要不然是刚刚结束,要不然是对现在还有影响.
since 不论什么时态,表示从哪一个时间点起；
for 不论什么时态,表示延续了多长时间.

那个选择为什么选c啊，她已经变了！第二个句子为什么不用现完？

举报夜色星辰

在变之前，she had been doing well 她一直都表现很好。强调动作、行为的延续性：一直都。从过去某时刻，一直延续，直到她变的那个时刻。第二个句子也是强调动作延续到讲话的这一刻仍在继续。 I have just read a novel. (意思是：I finished reading it) 完成了，读完一本小说，现在不读它了。I have been reading the novel (还没有读完，还在继续读）

所以第二个问题也清楚了，to abandon既不是修饰projects也不是修饰mental audit的区分定语和宾补的方法：定语是修饰名词的句子成分，名词不一定是宾语，也
