since ……

答：for与since都能与现在完成时连用，但区别较大：for后须接“时间段”，since后须接“时间点”，二者可以转换，均须与延续性动词连用，也可以与非延续性动词的否定式连用。二者引出的时间状语往往用 how long提问。如：He has been here for two years.=He has been here since two years ago.他来这里已有两年了。—How long have you had this book?这本书你买多久了?—For a week./Since a week ago.买一周了。We haven't heard from him for a month.我们已有一个月没收到他的来信了。since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而for则不能。如：He has taught here since he came to China.自从他来到中国就在这儿教书。 It is /has been an hour since he left here.他离开这儿已有一小时了。祝你新年快乐！学习进步！

since then

from then on

Since then

at from

from(since) that time或since then

1、用法不同。

这两个词都可以和表示时间的词语连用。一般说来，for后接一段时间(累计时间)，用以说明某事一直进行了多长时间；而since后接某一时间(过去的一个时间点)，用以表示某件事开始的时间。

2、语气不同。

since和for均含有“因为”之意。

但是for作为并列连词，语气较弱，所引出的句子一般放在后面，表示附带说明的理由或推断理由。

since比for语气稍强，一般用于表示“由于大家已知的事实”。

3、读音不同。

since的英式读法是[sɪns]；美式读法是[sɪns]。for的英式读法是[fə(r)]；美式读法是[fər]。

单词解析：

一、for

用法：

conj. (连词)

1）for是并列连词,引导的是并列从句,表示原因的语气很弱,一般是对结果作出推断性的补充说明或解释,不表示直接原因, for前多加逗号。

2）for用法较正式,很少用于口语,一般用于书面语。

二、since

用法：

prep. (介词)

1）since用作介词的意思是“从…以来,自从…之后”,其宾语常指过去的一个时间点,其含意通常指持续到说话时刻的动作或情况开始于什么时候。

2）since之后常接名词、动名词作其宾语, since then意为“从那以后”。

since用作副词表示“以前”时还可和long, ever连用。long since意为“好久以前”, not long since意为“就在不久前”, ever since意为“从那时起,此后一直”
