42、识他了。(表经历)2)用于till / until从句的差异 延续动词用于肯定句，表示做直到 瞬间动词用于否定句，表示到 ，才 He didnt come back until ten oclock.他到10 点才回来。 He slept until ten oclock.他一直睡到10点。典型例题1. You dont need to describe her. I _ her several times.A. had metB. have met C. metD. meet 答案B. 首先本题后句强调对现在的影响，我知道她的模样，你不用描述。再次，several times告知为反复发生的
