七年下册法（一）情一、 Can情 can 有一定的,但不能独立存在,它必与原形一起构成。

情can 没有人称和数的化。

其具体用法如下:1.表示 " 能、会 ",指力或体力方面的" 能力 " 。

例如 : Jim can swim, but I can吉’姆t会.游泳,但我不会。

2.表示 " 可能 ",常用于否定句或疑句中,指某种可能性。

例如 : Han Mei can't be in the classroom. 梅不可能在教室里。

Can he come here today, please 他今天能到里来3.表示 " 可以 ",常用于口中,指可或求做某事。

例如 : Can I have a cup of tea, please 我可以喝一杯茶You can go out.你可以出去了情can 的基本句型1.肯定句型 :主 +can+原形 +其它。

例如 : They can play basketball. 他能打球。

2.否定句型 :主 +can not(can't/cannot)+ 原形 +其它。

表示 "某人不能 (不会。

不可能 )做⋯⋯"。

其中 can't 是 can not 的略式 ,英国多写成 cannot 。

3.疑句句型分 :一般疑句句型和特殊疑句句型两种型。

⑴一般疑句句型 :Can+主 +原形 +其它。

表示 " 某人会 (能。

可以 )做⋯⋯ ".其肯定答用 ""Yes,主 +can."作答 ;否定答用 "No, 主 +can't." 作答。

(注意 :答中作主的人称代,根据句中的主作相的化。

其化:第一人称 ,第二人称答 ;第二人称 ,第一人称答;第三人称 ,第三人称答。

)例如 : ①-Can you sing an English song for us 你可以我大家唱一首英歌-Yes.行。

语法专题：how、how long、how far引导的特殊疑问句一、用法1. 引导问句表示”问候”或询问”状况”，以how引导问句向他人表示问候或询问某事或某人的进展或状况。

例如：how怎样问健康状况、做事的方式等He is fine/strong. How is he?I go home by bike. How do you go home?Everything is ok.How is everything?I’m getting well with my classmates.How do you get on with your classmates? It’s sunny.How is the weather today? 今天天气怎样? (相当于What’s the weather like today?)注意：礼貌用语”How do you do?”(你好!)不是向人提问,而是打招呼,它的答语仍是:”How do you do?”；”How are you?”(你好吗?)的答语为”Fine, thank you.” “I’m well/OK/all right.”等。

2. how long对时间、物品长度提出疑问。

回答时间长度时常根据实际情况选用:”about+时间段”、”for +时间段”或”since+时间点”。

例如：how long多久问一段时间，问物体的长短He has lived here for a year. How long has he lived here?The desk is one meters long. How long is the desk?I’ve worked in that factory for two years. How long have you worked in that factory?The bridge is 200 metres.How long is the bridge?3. how far多远，问距离。

新人教版｜七年级英语下册所有语法都在这，15分钟所有搞懂！一 . 神态动词can 的用法can+ 动词原形，它不随主语的人称和数而变化。

1.含有 can 的一定句：主语+can+ 谓语动词的原形 + 其余。

2.含有 can 的否认句：主语+can't+动词的原形 + 其余。

3.变一般疑问句时，把can提早： Can+ 主语 + 动词原形 + 其余？一定回答：Yes，主语 +can 。

2. What's the time?=What time is it?此刻几点了？3.时辰表达法：顺读法和逆读法。

顺读法：“钟点 + 分钟”直接读数字。

如： 7: 05 seven five；8:16 eight sixteen逆读法：借助介词past 或 to 表示，要先说分再说钟点。

a. 当分钟不超出30 分钟时（包含30 分钟），即< 或 =30 ，用 past 表示。

其构造为：“分钟+past+整点”意为“几点过几分”。

如： 1:25 twenty-five past oneb.当超出30 分钟时，即>30 ，用 to 表示。

其构造为：“所差分钟（即60 —所过分钟数）+to+下一个整点”，to 译成“差”，差几分钟到几点。

如： 4:38 twenty-two to fivec. 当分钟为30 分钟用half 表示，当分钟为15 分钟用 a quarter。

感叹句一般用how或者what开头，句末加感叹号。

what 修饰名词，how修饰形容词或副词。

具体句式如下：（1）what引导的感叹句：1）What a(an)＋形容词＋可数名词的单数形式＋主语＋谓语！What a clever boy he is！多么聪明的小男孩啊！2）What＋形容词＋可数名词的复数形式＋主语＋谓语！What interesting books the children are reading!孩子们读的书多么有趣啊！3）What＋形容词＋不可数名词＋主语＋谓语！What cold weather it is！多冷的天！（2）how引导的感叹句：1）How＋形容词或副词＋主语＋谓语！How lovely the baby is！这孩子真可爱！（lovely 为形容词）How fast he runs! 他跑地多快啊！（fast为副词）2） How＋形容词＋a(an)＋可数名词的单数形式＋主语＋谓语！How heavy a box they are carrying! 他们抬的箱子多重啊！3）How＋主语＋谓语！How time flies! 时间过得多快！2. －Who visited her grandma?－Becky did.本句的答语中的did是用来代替上文中的动词visited的。

例如：－Do you like music? 你喜欢音乐吗？－No, but my father does. （does= likes music）不，但是我父亲喜欢音乐。

－Do you think he is clever? 你认为他聪明吗？－I think so.（so 代替he is clever）我认为如此。

Unit 1语法小专题(Grammar Focus)语法精讲一、情态动词的基本用法情态动词是表示说话人的语气、情态等的一类词。

如:can(能,会)、may(可以),以后我们还将学到must(必须),should(应该),would(应该、想要)等。

情态动词在运用时有以下三方面的特征:1,情态动词无主语人称及单复数的变化。

eg: They can play the piano.She can speak a little English.You may watch TV after supper.2.情态动词在句中运用时，后接动词原形。

eg:The girl can sing English songs.I can play Chinese chess.3.含情态动词的肯定句变为一般疑问句时，将情态动词提至句首，后加“？”；变否定句时，在情态动词后加上“not”即可。

eg:This boy can dance well.→—Can this boy dance well?(一般疑问句）-Yes, he can./No, he can't.→This boy can't dance well.(否定句）二、情态动词can的用法小结can是情态动词,意为“能;会”,表示某人或某物具备的能力,还可用来提出请求,没有人称和数的变化后面直接接动词原形。

下面来看一下它的具体用法。

1,表示有能力做某事,意为“能;会"。

eg：I can speak English.我会讲英语。

He can play basketball. 他会打篮球。

2、表示许可,意为“可以"。

eg：You can sit here.你可以坐在这儿。

下面一起来看一下can的句型变换:(1)变为否定句变为否定句时在情态动词can后加not,缩写为can't。

eg:She can't play the piano.她不会弹钢琴。
