Eversincegettingtoknowyou,ican'tstopthinkingaboutyou为什么不用完

Question

Ever since getting to know you, i can't stop thinking about you为什么不用完

Answer 1

1.ever since 的结构：(作为连词)=since 完成时态---- ever since +主+动词简单过去式
例：I have known him ever since he was a child.
他从小我就认识他了.
这种用法同since 差不多,不过 ever since 比 since 用得少.
再如：We have lived in Shanghai ever since we came to China.(自从我们来到中国之后就住在上海.)
以上所说的 ever since 作为连词.
2.ever since 也可作为副词,解释“此后”（就一直...）
例：1）He fell ill at Christmas and has been ill ever since.
他在圣诞节生病了此后就一直不适.（has + be ill）
2）He left home last year and has been away ever since.
他去年离家走了,此后一直在外面.（has + be away）
3）He fell off his horse a week ago and has been in bed ever since.
一周前他从马背上跌下来,从那以后就一直躺在床上.
4）He went to Turkey in 1950 and has lived there ever since.
他在1950年去土耳其,此后就一直住在那里.
但此题要表达的是“禁不住做某事”,其句型是can't stop/help doing sth,借助情态助动词,而情态助动词很少有时态变化,但比较常考的是“情态助动词+have+done”,表示本应该做某事,其他情况时态变化很少,因此不能用现在完成时!
