小升初英语专项十：祈使句、感叹句和there be句型一、知识点回顾1.祈使句概念：表示命令、警告、提醒、建议、请求、叮嘱、号召等，谓语动词用原形。
主语you通常省略，句末用感叹号或句号。
肯定结构：Go and wash your hands.（去洗你的手。
——命令）Be quiet,please.（Please be quiet.）（请安静。
——请求）Let’s go home.(让我们回家吧。
——建议)否定结构：（1）Do型和Be型的否定式都是在句首加don't构成：Eg:Don't go at a red light! 不要忘记我！Don't be late for school! 上学不要迟到！（2）Let型的否定式有两种：“Don't + let +宾语+动词原形+ 其它成分”和“Let + 宾语+ not + 动词原形+ 其它成分”。
Eg:Don't let him go. / Let him not go. 别让他走。
（3）有些可用no开头,用来表示禁止性的祈使句。
如：No smoking! 禁止吸烟！No fishing! 禁止钓鱼！小试牛刀：将下列祈使句改成否定句。
(1)Let’s fly kites now.____________________________________________________________________(2)Let him stay at home alone.____________________________________________________________________2.感叹句概念：表示喜怒哀乐等强烈情感的句子。
一般以what或how引导。
(1)what引导的感叹句（主要修饰名词）①What +a/an+形容词+可数名词单数+（主语+谓语）！E.g:What a lovely dog it is!②What +形容词+可数名词复数+（主语+谓语）！E.g:What lovely dogs they are!③What +形容词+不可数名词+（主语+谓语）！E.g:What clean water it is!(2)how引导的感叹句（主要修饰形容词或副词）How +形容词/副词+（主语+谓语）！E.g:How fast he runs!有关感叹句的选择题或填空题————做题方法(1)先找主语和谓语（一般先确定谓语动词）有名词①可数名词单数——what a/an(2)再看主语前有无名词②可数名词复数③不可数名词what无名词———how小试牛刀：用what或how填空。
(1)____________a good boy!(2)____________good the boy is!把一个句子改写为感叹句————做题方法E.g：He is a very clever boy.(1)一断：从谓语后面把句子分成两半。
例句即He is后面断开(2)二倒：把断开的主谓放在名词后面。
例句即变为：a very clever boy.He is(3)三去：考虑到感叹句翻译时会有“多么，如此之类加强语气的附带词汇”，所以应去掉句子中有类似意思的单词（so,very,too,quite）以避免语义重复。
例句即变为：a clever boy.He is(4)四加：根据做填空题的方法，加上相应引导词，调整单词字母大小写以及标点。
例句即变为：What a clever boy he is!注意：时间地点等放在句子原来的位置。
E.g:She is so busy at home on the weekend.How busy she is at home on the weekend!小试牛刀：把下列句子改为感叹句。
They are strong tigers.____________________________________________________________________3.There be句型(1)就近原则①____________________________________________________________________②____________________________________________________________________(2)There be句型一般疑问句，回答不需要代词。
