问题描述:

the life we were used to __ greatly since 1992
A.change B.has changed C.changing D.have changed
请各位说一哈为什么,

be used to doing 过去曾做某事,过去习惯做某事
be used to do 过去常常做某事
the life we were used to __ greatly since 1992意思为自92年以来,我们的生活已经发生了巨大的改变,强调完成时态,首先就排除A,C,再根据意思就知道主语是the life,在此做整体含义。谓动词用单数。即B

应该选B,since是用完成时的标志,所以看到它就先排除A和C,又因为The life为单数,所以选B.

有since用完成时,life单数第三人称,综合这两条,B对

选 B 因为还原就是the life has changed 我们的生活改变从 1992年到现在

we were used to 是个定语从句,修饰the life的,意为我们曾习惯的生活从1994年就开始变化了。
句子的主体就是the life (定语从句)---greatly since 1992,因为主语是the life 要单三,所以可以排除A,D ,又C不合语法规则。
P.S如果是刚刚开始学现在完成式,就应该对since1992敏感,有它就差不多是完成式了,再根据语法判断。~0~

since 是加完成时的
the life we were used to,是我们已经习惯的生活 的意思
不要把TO 和change 看成搭配。

因为since 所以是完成时
主语是life 第三人称单数
综上 选b
the life(we were used to )has changed greatly since 1992
注意:括号里是定语 只起修饰作用哦

The life (we were used to) has changed greatly since 1992.
括号里的是修饰life的定语
