人教版英语九年级各单元语法梳理
 
Unit 1:How can we become good learners?
第一单元的语法重点是:"by+V-ing”结构详解;提建议的句式。
by+V-ing
★“by+V-ing”结构在句子中作方式状语,常用来表示“以、靠、借助、通过、用(某种方法或手段)”而达到某种预期的目的。该结构常用来回答 How ? 之类的问题。
★ 当 by 和表示交通工具的名词连用时,它与名词之间不用任何限定词,且名词用单数形式。
They often go to school by subway. 他们经常坐地铁上学。
★ by,in 和 with 都可以表示“通过;借助”。by 后接表示动作、行为的名词;in 表示“用某种语言;用某种材料”;with 后接表示物体或工具的名词。如:
You may send the book by post. 你可以通过邮局把书寄出去。英语时态总结

Unit 2:I think that mooncakes are delicious!
第二单元的语法重点是:宾语从句;反义疑问句;表达“花费”。
宾语从句
that,if 和 whatever 引导的宾语从句:
★ 宾语从句中连接词的选择
1. 由 that 引导的宾语从句:that 在从句中无词义,不作任何成分,常可省略。如:
Jenny said (that) she could finish her painting before supper.
I think (that) you are right.
2. 由 if 或 whether 引导的宾语从句:if 或 whether 引导宾语从句时,一般可通用,都表示“是否”。如:
I don't know if / whether she still works there.
I want to know if / whether there is a hospital in this street.
但在下列情况下,只能用 whether,而不能用 if:
(1)在 whether ... or not 或 whether or not 结构中,不能用 if。如:
Nobody knows whether or not it will rain.
(2)在介词之后用 whether。如:
I'm interested in whether he likes English.
★ 主从句时态的呼应
当主句是一般现在时态时,从句可用各种时态;
当主句是一般过去时态时,从句常用过去的某种时态。
但当从句叙述的是客观事实或一般真理时,即使主句为过去时,宾语从句仍然用一般现在时态。如:
He said he would spend his holiday in Dalian.
Our geography teacher told us that the sun rises in the east.
直击中考

-Don't mention it. _____ you have more questions,come to me any time.
A.If 
B.Because
C.Though
反义疑问句
①肯定陈述句+否定提问。如:
Lily is a student isn't she?
Lily will go to China,won't she?
②否定陈述句+肯定提问。如:
She doesn't come from China,does she?
You haven't finished homework,have you?
③提问部分用代词而不用名词如:
Lily is a student,isn't she?
④陈述句中含有否定意义的词
如:little,few,never,nothing,hard 等,其反意疑问句用肯定式。
如:He knows little English,does he?他一点也不懂英语,不是吗?
