Yours ____1. 祈使句是表示请求、命令、叮嘱、号召、
劝告等的句子; 通常省略主语you; 句中谓语
动词用动词原形; 句尾一般用降调; 祈使句的
开头是动词原形。
祈使句有肯定和否定两种：
e.g. Look?out!? 小心！
Wait?here?for?me!? 在这等我！ Grammar Come in, please! 请进！
　 Sit down, please. 请坐。
　 Let's go home. 我们回家吧。
否定的祈使句是在动词前(即句首)加Don't.
e.g. Don't talk in class! 不要在课常上讲话！
Don't open the window! 别开窗！
Don’t be late for school. 上学别迟到 !
Don’t smoking! 别吸烟!2. 情态动词have?to?的用法have to意思是“必须、不得不”, 它侧重于客观
上的必要和外界的权威。
1) 结构: 主语＋have?to＋动词原形＋其他
(一般现在时, 主语是第三人称单数时,
用has?to; 句子是过去时, 用had?to.) 如：We?have?to?wear?sneakers?for?gym?class.?
在体育课上, 我们必须穿运动鞋。
Tom?has?to?practice?the?guitar?every?day.?
汤姆每天必须练习弹吉它。
I?had?to?get?up?at?5:00?am?last?Monday.?
上周一, 我不得不早上5点起床。
2) 否定形式: 主语＋don’t?have?to＋动词原形
＋其他(一般现在时, 主语是第三人称单数时,
用doesn’t?have?to; 句子是过去时, 用
didn't?have?to)
e.g. Nick?doesn't?have?to?wear?a?uniform.
? 尼克不必穿制服。
We?didn't?have?to?do?our?homework?at?once.?
我们不必马上完成作业。3) 疑问句: Do (Does 或 Did)＋主语＋
have?to?＋动词原形＋其他
如: --Do?you?have?to?stay?at?home?on?weekends??
--Yes,?I?do.?/?No,?I?don't.?
周末你必须呆在家里吗？
是的, 我必须。/ 不, 我不必。
Did?he?have?to?go?to?bed?by?11:00?last?night??
昨晚, 他不得不11点前上床睡觉吗？?1) 表示能力, “会”, “能”(在第一册中已经学习
这种用法) 例如:
Can?you?play?the?guitar??你会弹吉它吗？
Judy?can?speak?a?little?Chinese.?
朱蒂会说一点中文。
I?can?dance?and?sing.?我能唱歌又能跳舞。3. 情态动词can的用法2) 表示允许、许可, “可以”、“能” (在这一课
中新学的词义) 例如:
Can?the?students?run?in?the?hallways??
学生们可以在走廊上跑吗?
We?can?eat?outside.?我们可以在外面吃东西。
Can?I?come?in??我能进来吗?注意: 同样是情态动词, can和have?to的用法
是有区别的, 和大部分情态动词一样，
can在否定句中, 直接在can后加上not，
在疑问句中, 把can放到主语前面，
并且没有人称和数的变化。Language Points1. --What are the rules? 规则是什么？
　--Well, we can't arrive late for class.
哦, 我们上课不能迟到。
1) rule规则, 可数名词, 构成的短语有：
　obey the rules 遵守规章
be against the rules
break the rules违反规章school rules 校纪 = the rules of the school
class rules 班规 = the rules of the class
※ rule还可以用作动词, 意为“统治, 支配”。
e.g. The king ruled the country 500 years ago.
　 500年前, 国王统治着这个国家。2) arrive “到达”, arrive是一个不及物动词，
不能直接跟表示地点的名词。如果要跟名词，
就必须加介词in或at。在“大地方”前加“in”；
在“小地方”前加“at”.
arrive in / at + 地点
get to +地点
reach +地点 (到达某地方 )e.g. When did you arrive in Shanghai?
你什么时候到的上海？
When we arrive at the school, it was 7:50.
当我们到达学校时，已经 7：50了。
※如果 arrive后不接名词，就不用介词：
e.g. After you arrive (here/there), please call me.
　　你到了(这里/那儿)后给我打个电话。 3) late “迟, 晚” (形容词或副词)
e.g. Why are you late? 你为什么迟到？
　 Sorry, I come late. 对不起, 我来晚了。
be late for＋n. (对)……迟到
e.g. Don't be late for work / class /meeting.
上班/上课/开会别迟到。 2.?hear, listen和sound都有“听”的意思，
但三者是有区别的。
1) hear “听说“, 侧重于”听”的内容。例如:
I'm?sorry?to?hear?that?you?are?ill.?
听说你生病了, 我很难过。
I?never?heard?such?an?interesting?story.?
我从来没听过这么有趣的一个故事。2) listen“听”侧重于“听”这一动作。例如:

3) sound“听起来”, 它是系动词, 后面
接形容词等。例如:

It?sounds?like?fun.?听起来挺有趣。3. out, outside
