2026-2027学年九年级英语上册期中重难点专项训练（人教版新教材）
专项03 语法精练Unit1-Unit4
语法讲义
Unit1 The Changing World
核心语法：现在完成时；used to do sth.
1. 现在完成时：have/has + 过去分词
含义：①过去动作对现在造成影响；②动作从过去持续到现在（for+时间段 / since+时间点）
肯定句：主语+have/has + done
否定句：主语+have/has + not + done
一般疑问句：Have/Has +主语 + done?
标志词：already, yet, ever, never, just, before, since, for, so far
⚠️辨析：have been to（去过，已回）；have gone to（去了，未回）；have been in（待在某地多久）
2. used to do sth. 过去常常做某事（现在不这样了）
否定句：didn’t use to do / used not to do
疑问句：Did sb. use to do…?
⚠️辨析：be used to do（被用来做）；be used to doing（习惯于做）
Unit2 Inspiring people
核心语法：it作形式主语
句型：
1. It is/was + adj. + of sb. to do sth.
形容词描述人的品质（kind, brave, wise, careless）
例：It was brave of him to save the boy.
2. It is/was + adj. + for sb. to do sth.
形容词描述事情特征（important, difficult, necessary, easy）
例：It is important for us to keep learning.
3. It is + adj. + that从句
例：It is amazing that he kept trying for years.
要点：it无实义，真正主语是后面的不定式/从句
Unit3 Smart Learning
核心语法：that / if / whether 引导宾语从句
1. that引导（陈述句变来，that无词义，常省略）
I think (that) reading helps a lot.
⚠️并列第二个that不能省
2. if / whether引导（一般疑问句变来，译为“是否”）
I wonder if/whether you have a good way to study.
⚠️只能用whether：介词后、whether…or not、whether + to do
3. 宾语从句三要素：引导词、陈述语序、时态
主现从任意；主过从必过；真理永一现
Unit4 Our Memory
核心语法：疑问词（what/who/where/when/why/how等）引导宾语从句
1. 引导词在从句中有词义，充当句子成分，不能省略
例：Do you know how memory works?
2. 语序：一律陈述语序：引导词+主语+谓语
XCould you tell me where is the library?
√Could you tell me where the library is?
3. 转换：主句主语=从句主语时，可简化为“疑问词+to do”
I don’t know what I should do. = I don’t know what to do.
