根据教育部课程标准与一线教学经验,人教版九年级英语第七单元的核心价值在于系统建立含有情态动词的被动语态的应用能力,这一语法点是中考英语的重要考查内容。本单元以”Teenagers should be allowed to choose their own clothes”为话题,将语法学习融入真实语境。

基本结构为:情态动词(should, can, must, may等) + be + 及物动词的过去分词。
例句与应用对比:
句型类型 | 主动语态例句 | 被动语态转换 |
|---|---|---|
表达允许 | Parents should allow? teenagers to make some choices. | Teenagers should be allowed? to make some choices. |
表达禁止 | The school should not allow? students to smoke. | Students should not be allowed? to smoke in the school. |
表达义务 | We must obey? the school rules. | The school rules must be obeyed. |
否定句与疑问句:
否定句:在情态动词后直接加not。例如:Teenagers should not be allowed? to drive at 16.
一般疑问句:将情态动词提到句首。例如:Should? teenagers be allowed? to have part-time jobs?
1. get/have sth. done 结构
意为“使某事被做”,动作常由他人完成。例如:Anna wants to get her ears 热播短剧 www.esoua.com pierced(安娜想打耳洞)。此结构中,过去分词(pierced, cut, repaired)表达被动含义。
2. enough 的用法
形容词/副词 + enough + to do sth.:足够…可以做某事。例如:They are not serious enough to make? their own decisions.(他们不够稳重,不能自己做决定。)
enough + 名词:足够的…。例如:We don’t have enough time.
3. regret 的用法辨析
regret doing sth.:后悔做过某事(事情已发生)。例如:I regret talking? back to my mom.(我后悔和妈妈顶嘴了。)
regret to do sth.:遗憾地要做某事(事情尚未做)。例如:I regret to tell? you that you failed the test.(我很遗憾地通知你考试没通过。)
