七八年级核心考点精讲精练专题十二感叹句、祈使句与固定句型【教材出处】七上Unit4Timetocelebrate：祈使句（Let's…用法）八下Unit1Careertalks：感叹句（What/How引导）八上Unit3Makeithappen!：固定句型（It's+adj.+for/ofsbtodo）八下Unit3Whatmakesagreatteam?：固定句型（Ittakessb+时间+todo；too…to…）七下Unit2Goforit!：固定句型（Whynot…?/Whydon'tyou…?）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。（一）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）（二）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________beautifulgirlsheis!→有名词girl→What________beautifulthegirlis!→无名词，只有形容词→How________fastheruns!→副词fast，无名词→How________interestingbookstheyare!→名词books→What________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Whatabeautifulgirlsheis!=Howbeautifulthegirlis!Whatdeliciousfooditis!=Howdeliciousthefoodis!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。（一）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Let's…，shallwe?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+todosthit为形式主语，真正主语是后面不定式todoforsb：形容词描述事情本身性质（easy/difficult/important/necessary）It'simportantforustolearnEnglishwell.ofsb：形容词描述人的品格品质（kind/nice/clever/foolish/polite）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、副词Sheissoyoungthatshecan'tgotoschool.so+形+a/an+单数可数名词+thatso修饰形容词再接单数名词Sheissoyoungagirlthatshecan'tgotoschool.such+a/an+形+单数可数名词+thatsuch搭配完整名词短语Sheissuchayounggirlthatshecan'tgotoschool.such+形+复数名词+thatsuch修饰复数名词短语Theyaresuchinterestingbooksthateveryonelikesthem.such+形+不可数名词+thatsuch修饰不可数名词短语Itissuchdeliciousfoodthateveryoneenjoysit.互换公式：so+形容词+a/an+单数名词=such+a/an+形容词+单数名词
