单元语法小专题(Grammar Focus)语法精讲 一、祈使句的运用祈使句是表示命令、请求别人做某事或征求对方意见的句子。祈使句很大一部分直接用动词原形开头，成了典型的“无主句”。如：Come to school earlier next time.下次早点来学校。Li Ping，answer the question，please.李萍，请回答这个问题。祈使句在运用中，一般常可在句首或句尾加上“please”，please意为“请”，放在句尾时一般用“，”与前面的句子隔开，祈使句通常又可分为下面几种类型：1肯定祈使句，一般将动词原形放在句子开头。如：Stand up，please.起立。Be more careful next time.下次仔细点。2否定祈使句，一般在肯定祈使句前加上dont构成，表示“不要”之意。如：Lucy，dont watch TV any more.露西，不要再看电视了。Please dont do it like that！请不要再像那样做了！3以“let”开头的祈使句，let意为“让”，一般句子结构为“let sb. do sth.”。如：Let us go out for a walk，Mr. Wu.吴先生，让我们去外面散步。Let your father come to visit me this afternoon.让你爸爸今天下午来见我。二、可数名词与不可数名词普通名词分为可数名词和不可数名词。可数名词可以用具体的数词来修饰，也可以用“数词计量名词of可数名词的复数形式”来表示。如：three apples三个苹果；two bags of watermelons两袋西瓜不可数名词没有复数形式，表示量时用“数词计量名词of不可数名词”结构。如：a cup of milk一杯牛奶可数名词的量可以用how many提问；不可数名词的量可以用how much提问。some，any，a lot of，lots of等既可以修饰可数名词，又可以修饰不可数名词。语法精练.用括号内所给单词的适当形式填空。1. _(open)the door，please!2_(not make)any noise in class!3How many _(tomato)do we need?4How much _(water)is there in the bottle?5Let him _(go)，please.6There is a lot of _(water) in the bottle.7The _(child) are playing games on the playground now.8Can you give me two bottles of _(orange)，please.按要求完成下列句子，每空一词。9You must listen to the teacher carefully.(改为祈使句)_ _ the teacher carefully，please.10You cant pour dirty water into the river.(改为祈使句)_ _ dirty water into the river.11Please close your book！(改为同义句)_ _ please close your book?12I have two brothers.(对画线部分提问)_ _ _ _ you _？13There is a_little bread in the fridge.(对画线部分提问)_ _ _ _ _ in the fridge?14There are five books on the desk.(对画线部分提问)_ _ _ are there on the desk?15I would like five_pieces_of bread.(对画线部分提问)_ _ _ would you like?.根据汉语意思完成句子，每空一词。16请看黑板。_ _ the blackboard，please.17你们班上有多少学生？_ _ _ _ _ in your class?18下次不要迟到。_ _ late next time.19这件大衣多少钱？_ _ is the coat?20我们回家吧。_ _ home.21我想要一杯酸奶。I would like _ _ _ _.22在我们班里有五十名学生。There _ fifty _ in our class.单元语法小专题(Grammar Focus).1.Open2.Dont make3.tomatoes4.water5.go6.water7.children8.orange.9.Listen to10.Dont pour11.Could you12.How many brothers do；have13.How much bread is there14.How many books15.How much bread.16.Look at17.How many students are there18.Dont be19.How much20.Lets go21.a cup of yogurt22.are students
