专题11 重点语法知识梳理：情态动词及专练60题(解析版)-六年级英语下学期期末考点大串讲
专题11 重点语法知识梳理三：情态动词及专练60题（解析版）Ⅰ.情态动词一、概论情态动词是一种特殊的助动词，具有下列特征：1. 情态动词具有一定的词义，能表达某种看法；如：can能，may可以，must必须，need需要，等等；2. 情态动词不能单独作谓语，只能和实义动词的原形一起构成复合谓语；如：You can stay here before 5:00 o’clock. 你可以在这呆到五点钟。
We must have a talk right now. 我们现在就必须谈谈。
3. 情态动词无人称变化，即任何事物做主语对情态动词来讲都无变化。
但是情态动词有时态变化。
时态变化会在以后分单词讲解，此处仅以can为例，看看人称对情态动词是否无影响：如：I can dance very well.我舞跳得很好。
He can play basketball pretty well.他篮球打得很好。
I know you can play the piano fairly well.我知道你钢琴弹得很棒。
They all can swim quite well.他们游泳游得相当好。
二、常见的情态动词1.can/can’t,能够/不能① 表示"能、会",指脑力或体力方面的"能力"。
例如:Jim can swim but I can't.吉姆会游泳,但我不会。
① 表示"可能",常用于否定句或疑问句中,指某种可能性。
例如:Han Mei can't be in the classroom.韩梅不可能在教室里。
Can he come here today,please?请问他今天能到这里来吗？① 表示"可以",常用于口语中,指许可或请求做某事。
例如:Can I have a cup of tea,please?请问我可以喝一杯茶吗？You can go out.你可以出去了？① 否定句型为: 主语+c an not(can't/cannot)+动词原形+其它。

六年级英语下册语法特训5情态动词must(含答案)译林版三起
语法特训5：情态动词must〔含答案〕一、must和can辨析must和can都是情态动词。
情态动词不能单独使用，必需与其后的动词共同构成谓语，其后接动词原形。
情态动词本身没有人称和数的变化。
1.must表示必需，否认时表示禁止，语气比拟剧烈。
例如：You must finish your homework now.你现在必需完成家庭作业。
You mustn't cross the road now.你现在不能过公路。
2.must也可以表示说话人的主观推想。
例如：It's seven o'clock.Tom must be at home.现在七点钟。
汤姆确定在家。
3.can通常表示力量〔体力、学问、技能〕，或表示恳求和允许。
例如：The robot can talk.这个机器人能说话。
You can get there by bus.你可以乘公共汽车到那儿。
Can I have some water?我能喝一些水吗？二、must的根本句型1.确定句结构主语十must十动词原形〔十其他〕。
例如：I must spell these new words.我必需拼写这些生词。
2.否认句结构主语十must十not十动词原形〔十其他〕。
must not=mustn't。
例如：You must not/mustn't smoke here.你不能在这里吸烟。
3.一般疑问句结构Must十主语十动词原形〔十其他〕？例如：Must I clean all the rooms?我必需清扫全部的房间吗？Yes, you must./No, ,你必需〔清扫〕。
/不,你不必(清扫)。
留意：must开头的一般疑问句，假设作否认答复，应用needn't或don't have to，而不用mustn't (由于mustn't表示禁止，意为“绝不能〞；而否认答复是想表示没有必要，不是绝不能做某事，所以否认答复用needn't或don't have to)。
