Unit 2 No Rules, No Order语法归纳和练习- 2024-2025学年人教版英语七年级下册
Unit 2 No Rules, No Order 语法聚焦:祈使句&情态动词&频度副词
一、语法归纳
语法点 1:祈使句
1.祈使句的定义
祈使句用于表达命令、请求、劝告、警告、禁止等语气。它的主语通常是第二人称 you,但一般省略不写。
2.祈使句的结构
肯定祈使句:动词原形(+ 宾语 + 其他成分)。
例如:
Open the door, please.(请打开门。)
Come here early.(早点来这儿。)
Let's go shopping.(咱们去购物吧。这里 Let's 是 Let us 的缩写形式,也是一种特殊的肯定祈使句结构 )
否定祈使句:Don't + 动词原形(+ 宾语 + 其他成分)。
例如:
Don't run in the hallways.(不要在走廊里跑。)
Don't be late for class.(上课不要迟到。这里 be 动词原形用于祈使句中表示 “处于某种状态” )
Never eat in the classroom.(绝不要在教室里吃东西。Never 也可用于构成否定祈使句,语气比 Don't 更强 )
3.祈使句的特点
祈使句通常没有主语,句末用感叹号或句号,读时一般用降调。当祈使句表示请求时,通常在句首或句末加上 please,句末加 please 时,前面要用逗号隔开。例如:Please come in. 或 Come in, please.(请进。)
语法点 2:情态动词 can 的用法
1.表示能力
can 表示某人 “能;会” 做某事,即具备某种能力。其否定形式是 can't(cannot 的缩写),表示 “不能;不会”。
例如:
I can speak English.(我会说英语。)
She can't play the guitar.(她不会弹吉他。)
Can you swim Yes, I can. / No, I can't.(你会游泳吗?是的,我会。/ 不,我不会。)
2.表示请求许可
在口语中,can 可以用来向对方请求许可,意为 “可以”,常用于非正式场合。其否定回答常用 can't 或 mustn't(表示 “禁止;不允许”)。
例如:
Can I have a glass of water (我可以喝杯水吗?)
Yes, you can.(是的,你可以。)
No, you can't /mustn't.(不,你不可以。)
3.can 与 be able to 的区别
can 只有一般现在时和一般过去时(could)两种时态形式,而 be able to 有更多的时态变化,可以用于各种时态。
例如:
I will be able to drive a car next year.(明年我将能开车。这里不能用 can,因为表示将来的能力 )
在过去时态中,could 常用来表示过去一般的能力,即过去 “能,会” 做某事;而 was/were able to 则强调过去成功地做了某事(=managed to do sth. 或 succeeded in doing sth.)。
例如:
I could run faster when I was young.(我年轻时能跑得更快。只是说明过去有跑步快的能力 )
He was able to escape from the fire yesterday.(他昨天成功地从火灾中逃了出来。强调成功做到 )
语法点 3:频度副词的进一步运用(本单元延续上一单元内容)
1.频度副词与祈使句或情态动词连用时的位置
当句子中出现祈使句时,频度副词通常放在祈使句动词之前。例如:Always listen to your teachers carefully in class.(在课堂上要总是认真听老师讲课。)
当句子中含有情态动词时,频度副词一般放在情态动词之后,实义动词之前。
例如:You should always keep your room clean.(你应该总是保持你的房间干净。)
2.对含有频度副词的句子提问
依旧用 how often 来对频度副词进行提问,询问动作发生的频率。
例如:
They often play basketball after school.(对 often 提问)
How often do they play basketball after school
