Question

【題目】用since或for完成句子。

【1】John has been a member of the Party 2003.

【2】We have studied English many years.

【3】He has had this English dictionary three months.

【4】The couple have lived here they moved here three years ago.

Answer 1

【答案】

【1】since

【2】for

【3】for

【4】since

【解析】

for和since在現(xiàn)在完成時的句子中引導時間狀語從句，since后面接過去的某一具體時間點，“since+過去的時間點”表示從這一時間點到現(xiàn)在的一段時間。兩者引導時間狀語從句的謂語要用短暫性動詞，并且要用一般過去時。由此可知1、4小題用since。2、3小題用for。
