(二)重难点语法考点详解
考点 1:两组进行时态辨析
1. 现在进行时(am/is/are doing)
侧重此刻或现阶段正在开展的行为,these days为本单元高频标志词,指代近期一直在做的事。
例:They are discussing their future plans these days.
这些日子他们一直在探讨自己未来的规划。
补充特殊用法:come/go/leave 等位移动词,可用现在进行时表即将发生的将来动作。
例:We are leaving our junior high school in one month.
2. 过去进行时(was/were doing)
锁定过去某一个精准时间点,动作正在进行;常搭配 when、while 引导时间状语从句。
• at this time last night 昨晚这个时刻
• when 引导短暂动作,主句多用过去进行时
例:I was practicing my speech when my teacher came into the classroom.
老师走进教室的时候,我正在练习演讲稿。
考点 2:现在完成时标志性副词辨析
1. already:多用于肯定句,置于助动词之后;
2. yet:多用于否定句、疑问句,常放句末;
3. ever(曾经)、never(从未)多用于疑问句、陈述句;
4. before 单独置于句末,为现在完成时标识。
例句:I have never forgotten the warm memories from junior high school yet.
考点 3:时态结合被动语态
六大时态均可对应被动结构,整理常用被动形式:
1. 一般现在被动:am/is/are done
2. 现在进行被动:am/is/are being done
3. 一般过去被动:was/were done
4. 过去进行被动:was/were being done
5. 一般将来被动:will be done
6. 现在完成被动:have/has been done
例句:Our graduation yearbook has been made by the whole class.(现在完成被动)
考点 4:易混时态区分
1. these days:现在进行时,现阶段一直在做;
2. in those days:一般过去时,过去那段时期;
3. at this time last year:过去进行时,过去特定时刻;
4. so far /up to now:现在完成时,时至今日。
