译林版八年级下册英语Unit1-4单元重点语法夯实应用专项训练

 

核心语法知识点拨

       现在完成时

1. 基本结构

肯定：主语+have/has+动词过去分词

否定：主语+haven’t/hasn’t+动词过去分词

一般疑问句：Have/Has + 主语 + 动词过去分词？

特殊疑问句：特殊疑问词 + have/has + 主语 + 动词过去分词？

2. 标志词与时间状语：already、just、ever、never、before，yet(常用于否定句、疑问句)等

表持续时长：for + 时间段、since + 时间点/一般过去时从句

其他高频：so far、up to now、in the past few years

3. ★高频易混易错

have/has been to：去过某地，已返回

have/has gone to：去了某地，尚未回来

have/has been in：在某地停留，后接时间段

4. for & since (高频考点)

for和since表持续时长时，谓语动词须用延续性动词；

短暂性动词转换：buy→have、borrow→keep、leave→be away、die→be dead、join→be in等。

5. 现在完成时与一般过去时辨析

现在完成时：侧重过去动作对当下造成的影响，或动作从过去持续到现在，无明确过去时间状语

一般过去时：单纯陈述过去事实，与现在无关联，常搭配yesterday、last…、…ago、just now等

判断技巧：有具体过去时间用一般过去时；强调对现在影响、持续状态用现在完成时

       疑问词+动词不定式

1. 基础结构：疑问词what/which/when/where/how/who + to do

2. 常搭配动词：know, learn, see, hear, ask, tell, decide, explain, forget等

3. 易错提醒：what to do 后无需加宾语；how to do 后面必须补充完整宾语

       must 与 have to 用法辨析

1. must：表主观上的必须；否定mustn’t 意为禁止、绝不允许；无人称和时态变化，后接动词原形

2. have to：表客观条件下不得不；否定don’t/doesn’t/didn’t have to 意为不必；有人称及时态变化，后接动词原形
