七年级英语句型转换专项练习题合集

七年级英语句型转换专项练习题合集在七年级英语学习中，句型转换是考查语法应用、词汇灵活度与语言转换能力的核心题型。它要求我们在理解句意的基础上，熟练运用语法规则对句子结构、语气、表达形式进行调整。这份练习题合集将从五大常考题型入手，结合解题思路与实战训练，帮助你系统突破这一重难点。一、肯定句变否定句/一般疑问句解题思路：先判断谓语动词类型（be动词/情态动词/实义动词），再针对性变形：若含be动词（am/is/are）或情态动词（can/may/must等）：变否定句在其后加`not`；变一般疑问句将其提至句首。若含实义动词：主语为第三人称单数时，否定句加`doesn't`、动词还原；一般疑问句用`Does`开头、动词还原。主语为非三单时，否定句加`don't`；一般疑问句用`Do`开头。例题示范1.原句：*Sheisastudent.*否定句：Sheisn'tastudent.一般疑问句：Issheastudent?2.原句：*Heplaysbasketballeveryday.*否定句：Hedoesn'tplaybasketballeveryday.一般疑问句：Doesheplaybasketballeveryday?实战训练1.TheyarefromChina.（变否定句+一般疑问句）2.Wehavelunchatschool.（变否定句+一般疑问句）3.ThegirlcansingEnglishsongs.（变否定句+一般疑问句）二、对划线部分提问（特殊疑问句）解题思路：先判断划线部分的成分（时间、地点、事物、原因、方式等），选择对应疑问词（`what/where/when/why/how/who`等）；再将剩余部分变为一般疑问句（对主语提问除外，直接用疑问词替代主语）。例题示范1.原句：*Hegoestoschoolbybike.*（对`bybike`提问）分析：`bybike`表方式→用`how`；剩余部分变一般疑问句（主语`he`+实义动词`goes`→加`does`、动词还原）。提问：Howdoeshegotoschool?2.原句：*Theboyinblueismybrother.*（对`Theboyinblue`提问）分析：划线部分是主语（人）→用`who`；疑问词作主语，剩余部分保持陈述句语序。提问：Whoisyourbrother?实战训练1.Shegetsupat6:00everymorning.（对`at6:00`提问）2.Theyarereadingbooksinthelibrary.（对`inthelibrary`提问）3.IlikeEnglishbecauseit'sinteresting.（对`becauseit'sinteresting`提问）4.Theredpenismine.（对`Theredpen`提问）三、同义句转换解题思路：抓住原句核心语义，用同义词/短语或不同句型结构替换（如`too...to...`与`so...that...`、`spend...on...`与`Ittakes...to...`等），确保句意不变。例题示范1.原句：*Heistooyoungtogotoschool.*同义句：Heissoyoungthathecan'tgotoschool.2.原句：*Ispendanhouronmyhomeworkeveryday.*同义句：Ittakesmeanhourtodomyhomeworkeveryday.实战训练1.Shewalkstoschooleveryday.（用“go...onfoot”改写）2.ThebookissoexpensivethatIcan'tbuyit.（用`too...to...`改写）3.Iusuallygotobedat9:30.（用“halfpastnine”改写）4.Heisgoodatplayingfootball.（用`doeswellin`改写）四、陈述句变感叹句解题思路：感叹句分两种结构：`What+(a/an)+形容词+名词+主语+谓语!`（中心词为名词，可数单数用`a/an`，复数/不可数名词不用）；`How+形容词/副词+主语+谓语!`（中心词为形容词/副词）。例题示范1.原句：*Theflowerisbeautiful.*感叹句：Howbeautifulthefloweris!/Whatabeautifulfloweritis!2.原句：*Theflowersarebeautiful.*感叹句：Whatbeautifulflowerstheyare!实战训练1.Thegirlisveryclever.（用`How`和`What`各写一句）2.Theweatherisfinetoday.（变感叹句）3.Herunsveryfast.（变感叹句）4.It'saniceday.（用`How`和`What`各写一句）五、陈述句变祈使句解题思路：祈使句以动词原形开头（省略主语`you`），表命令、请求；否定祈使句在句首加`Don't`。例题示范1.原句：*Youshouldcleanyourroom.*祈使句：Cleanyourroom.2.原句：*Youcan'tplayinthestreet.*否定祈使句：Don'tplayinthestreet.实战训练1.Youshouldbequietinthelibrary.（变祈使句）2.Youmustn'ttouchthemachine.（变否定祈使句）3.Youcangohomenow.（变祈使句）4.Youshouldnoteatinclass.（变否定祈使句）学习小贴士1.分析结构：先确定句子的谓语类型、成分（主语/宾语/状语等），再套用对应规则。2.细节把控：注意单复数、时态、
