since可以接doing吗
@袁舒4397：since后一般加现在完成时,那加doing进行时态可以吗?例句说明 - 作业帮
简露15989036498…… [答案] 现在完成时+since+一般过去时,如:I have worked here since i came here. 现在完成进行时+since+一般过去时,如:I have been working here for 10 years since i came here.这里强调动作仍然在继续.
@袁舒4397：有since doing sth.用法吗 - 作业帮
简露15989036498…… [答案] 没有这种用法. since+从句,主句.表已知必然理由,原因状语从句 since you have been here,you may stay here as well. 主句.(完成时态)since+从句(过去式).时间状语从句 it has been 3 years since I left home.
@袁舒4397：since 能加doing(v.ing )吗?有做过这样的题 -

@袁舒4397：求解since后面可以加have done 的形式吗 -
简露15989036498…… 完全可以,表示既然或因为的意思时就可以,since有三个意思,一般用于现在完成时,但还有其它意思,要根据具体情况而定,要灵活掌握运用.
@袁舒4397：since一定要用完成时么 i love you since last summer 这句话是对是错? -
简露15989036498…… i love you since last summer 错 since的主句也可用完成进行时,I have been loving you since last summer
@袁舒4397：since后是一定接现在完成时吗 -
简露15989036498…… 不一定,since还可以做连词,表示因为的意思;用作连词 (conj.): 既然; 因为 [例句]He must have taken the book since it isn't here.他一定是把书拿走了,因为书已不在这里了.Since you can't answer the question, perhaps we'd better ask someone else.既然你无法回答这个问题,我们最好再问问别人.保证正确率,望采纳如有疑问,请追问
@袁舒4397：since后面加什么时态 -
简露15989036498…… since,副词 adv(常用于现在完成时或过去完成时),介词(常用于现在完成时或过去完成时). since后面从句用一般过去时. 例:I've made great progress in English since I came to this school. 自从我来到这个学校以来;我在英语上取得...
@袁舒4397：since在原因状语从句中 延续性动词与非延续性动词都可接? -
简露15989036498…… since在时间状语从句中,延续性动词与非延续性动词都可接.接短暂性动词时表示从这个动作发生之时算起一直到现在的这一段时间.接延续性动词时表示从这个动作结束之时算起起到现在的这一段时间.如:He has been in the school since 1998. 他1998年以来一直在这所学校工作.He has been in the company since he studied in Nanchang University. 他南昌大学毕业后一直在这家公司工作. since在原因状语从句中也是延续性动词与非延续性动词都可接.但那没有多大的探讨意义.
@袁舒4397：since前面能用瞬间动词吗,举例. -
简露15989036498…… 有时可以.since不但有“自从...＂的意思,还表示”既然…“,这时就无所谓短暂性动词或延续性动词了.例如:You can go home since he comes.既然他来了,你就可以回家了.但在表示”自从“的意思时,一定要用延续性动词.不过也有例外情况,比如若since前的短暂性动词是否定式,此时也可以用.例如:He hasn't bought this book since 3 years ago.他自从3年前就没买过这本书.例子举得不太好,但是否定词+短暂性动词是可以加since表示自从的.
@袁舒4397：since的用法: since后面可以接什么 -
简露15989036498…… since about six years 是错误的. since 用于现在完成时中,后面跟过去的时间或者跟一般过去时的动作. 例如: She has lived here since about six years ago. =She has lived here since 2007.
简露15989036498…… [答案] 现在完成时+since+一般过去时,如:I have worked here since i came here. 现在完成进行时+since+一般过去时,如:I have been working here for 10 years since i came here.这里强调动作仍然在继续.
