♦Unit4Timetocelebrate：祈使句(Let's...用法)

♦八下Unit1Careertalks：感叹句(What/How引导)

♦七下Unit2G。forit!：固定句型(Whynot…？/Whydontyou…？)

♦八上Unit1Thisisme：固定句型(hadbetterdo/hadbetternotdo)

【考点精讲】

考点一感叹句

感叹句用于抒发惊讶、喜悦、赞美等强烈情绪，句末用感叹号，由What、How引导。

(-)四种基础结构

引导词句式结构例句

WhatWhat+a/an+形容词+可数名词单数+主+谓！Whatabeautifulgirlsheis!

WhatWhat+形容词+可数名词复数+主+谓！Whatbeautifulflowerstheyare!

WhatWhat+形容词+不可数名词+主+谓！Whatdeliciousfooditis!

HowHow+形容词/副词+主+谓！Howbeautifulthegirlis!

补充：

a/an判断标准：名词发音以元音音素开头用an,辅音音素开头用a

Whataninterestingstory!（元音音素开头）

Whatausefulbook!（辅音音素开头）

（-）What与How快速区分口诀

后有名词短语用What,只有形/副无名词用How

1.beautifulgirlsheis!—>有名词girl—>What

2.beautifulthegirlis!—>无名词，只有形容词—>How

3.fastheruns!—>副词fast,无名词—>How

4.interestingbookstheyare!一名词books-What

5.interestingthebooksare!—>只有形容词—►How

（三）口语简化形式

可省略主语+谓语，只保留感叹部分：

Whatabeautifulgirl!（省略sheis）

Howwonderful!（省略itis）

（四）What、How句型互换

核心：What后名词放到How句主语位置，形容词不变

1.Whatabeautifulgirlsheis!=Howbeautifulthegirlis!

2.Whatdeliciousfooditis!=Howdeliciousthefoodis!

3.Whatinterestingbookstheyare!=Howinterestingthebooksare!

考点二祈使句

表命令、请求、劝告、建议，主语you默认省略，谓语一律用动词原形。

（-）三种基础句式

句式结构例句

肯定祈使句动词原形+其他Openthedoor,please.

否定祈使句Don't/Never+动词原形+其他Don'tbelate./Nevergiveup.

Let型祈使句Let+宾语+动词原形Letmehelpyou.

易错提醒：否定不加to

Don'ttobelate.

Don'tbelate.

（二）Let's与Letus对比

短语含义反意疑问句例句

Let's包含听话人，咱们shallwe?Let'sgo,shallwe?

Letus不包含听话人，请允许我们willyou?Letusgo,willyou?

（三）祈使句统一反意疑问句规则

i.Let's...,shallwe?

2.所有其他祈使句（肯定/否定、Letus）,统一用willyou?

Openthedoor,willyou?

Don'tbelate,willyou?

Letusgo,willyou?

考点三教材核心固定句型

1.It's+形容词+for/ofsb+todosth

it为形式主语，真正主语是后面不定式todo

forsb：形容词描述事情本身性质（easy/difficuk/important/necessary）

It'simportantforustolearnEnglishwell.

ofsb：形容词描述人的品格品质（kind/nice/clever/foolish/polile）

It'skindofyoutohelpme.

2.Ittakes/took/willtakesb+时间+todosth

含义：做某事花费某人多长时间，take随时态变形

Ittakesmehalfanhourtogettoschool.（一般现在时）

Ittookhertwohourstofinishthework.（一般过去时）

Itwilltakeusthreedaystogetthere.（一般将来时）

3.so...that.../such...that...如此..以至于....

结构用法例句

so+形/副+thatso后直接加形容词、Sheissoyoungthatshecan'tgotoschool.

副词

so+形+a/an+单数可数名词SO修饰形容词再接单Sheissoyoungagirlthatshecan'tgoto

+that数名词school.

such+a/an+形+单数可数名such搭配完整名词短Sheissuchayounggirlthatshecan'tgoto

词+that语school.

such+形+复数名词+thatsuch修饰复数名词短Theyaresuchinterestingbooksthateveryone

语likesthem.

such+形+不可数名词+thatsuch修饰不可数名词Itissuchdeliciousfoodthateveryoneenjoys

短语it.

互换公式：S0+形容词+a/an+单数名词=such+a/an+形容词+单数名词

sobeautifulagirl=suchabeautifulgirl

4....enoughtodo.../too...to...

结构含义例句

形/副+enough+to足够……可以做……Sheisoldenoughtogoto

doschool.

too+形/副+todo太……而不能……（自带否定，不加Sheistooyoungtogotoschool.

not）

易错点：enough修饰形容词/副词后置

□enoughold

□oldenough

5.Whynot...?/Whydon*tyou...?

表委婉建议：为什么不……？后均接动词原形

Whynotgotothepark?

Whydon'tyougotothepark?

6.hadbetter（not）dosth

最好做/最好不要做，口语缩写'dbetter,后接动词原形

Youhadbetterfinishyourhomeworkfirst.

Youhadbetternotstayuplate.

四、失分点整理

1.What/How混用

□Ilowbeautifulgirlsheis!

□Whatabeautifulgirlsheis!（后有名词girl）

□Whatbeautifulthegirlis!

□Howbeautifulthegirlis!（无名词）

2.祈使句反意疑问混淆

□Let'sgo,willyou?

□Let'sgo,shallwe?

□Letusgo,shallwe?

□Letusgo,willyou?

3.for/of区分不清

□It'skindforyoutohelpme.

□It'skindofyoutohelpme.（kind形容人品格）

□It'simportantofustostudyhard.

It'simportantfbrustostudyhard.（important形容事'情）

4.so/such结构错误

□Itissointerestingbookthateveryonelikesit.

Itissuchaninterestingbookthateveryonelikesit.（后接名词短语）

口Thebookissointerestingthateveryonelikesit.（后接形容词）

5.enough位置错误

□Heisenougholdtogotoschool.

□Heisoldenoughtogotoschool.

6.hadbetter否定多加to

□Youhadbetternottogo.

□Youhadbetternotgo.

五、九年级衔接预览

1.Unit2Onthemoney：大量使用Whynot、Whydon'tyou,hadbetter提建议；

2.Unit5Afinebalance：高频使用so…that…、such…that…引导结果状语从句;

复习重点：感叹句辨析、祈使句反意疑问、for/of句型、so/such与too/enough结构。
