语法提升
现在完成时（2）
考向1 含for或since的现在完成时
要表达某一行为或状态从过去某时间一直持续到现在
（包括“现在”在内），甚至还可能延续下去，我们也可以
借助现在完成时，此时常与“for+时间段”或“since+过去的
时间点/从句”连用。
I have lived in Beijing for 5 years.我在北京住了5年了。
She has worked at this company for a long time.她在
这家公司工作很久了。
I have known him since 2018.我从2018年就认识他了。
He has studied English since he was 6 years old.他从
6岁就开始学英语了。
含for和含since的现在完成时的句子有时可互相转换。

I’ve lived here since 13 years ago.
I’ve lived here for 13 years.
It has been 13 years since I began to live here.

个酒店住了两周了。

考向2 现在完成时中的谓语动词
在含有现在完成时的肯定句中，与“for+时间段”或
“since+过去的时间点或从句”连用的动词必须为延续性动
词。延续性动词表示能够持续的动作，可以与表示一段
时间的状语连用。常见的延续性动词有have、live、teach、
learn、work、study、know等；常见的非延续性动词
（词组）有come、go、leave、start、die、finish、
become、join、buy、get married等。

典例 按要求完成句子，每空一词。
（达州中考）His brother joined the army three years
ago.（改为同义句）
His brother ____ _____ in the army for three years.
has
been
[解析] 原句意为“他哥哥三年前参的军”。根据“for three
years”可知，时态应用现在完成时，且谓语动词应为延续
性动词；be in the army“参军”为延续性动词词组；主语
是“His brother”，助动词应用has。故填has been。
