(一)be supposed to的用法小结语法讲解 be supposed to do sth.意为“应该做某事”，其中to为不定式符号，后跟动词原形，可与should do sth.互换，两者多用于口语中。也可等同于ought to do sth.，但使用较少，多用于正式文体中。考向一当be supposed to的主语是人时，意思为“某人应该……”，表示劝告、建议、义务、责任等，相当于情态动词should。
eg：Everyone is supposed to wear a seat belt in the
car. 每个人在小汽车里都应该系安全带。
Teachers are supposed to treat all the students alike.
老师们应该对所有的学生一视同仁。典例The students ought to wear school uniforms when they're at school. (贵州黔西南)
A．are supposed to B．are allowed to
C．would like to D．love toA【解析】句意：当学生们在学校的时候应该穿校服。ought to的意思是应该，后跟动词原形。be supposed to do sth.应该做某事；be allowed to do sth.被允许做某事；would like to do sth.愿意做某事；love to do sth.喜欢做某事。故选A。考向二 be supposed to的否定结构为be not supposed to，常用于口语中，意为“不准，不得，不应当”。
eg：She was not supposed to be angry about that.
她不应当为那件事而生气。
You are not supposed to make so much noise
when the child is sleeping.
当孩子睡觉的时候，你不应该这么吵。典例 You are supposed to smoke here.(改为否定句)
You ________ ________supposed to smoke here.【解析】be supposed to的否定结构为be not supposed to
意为“不准，不得”。are not考向三当be supposed to用于过去时时，常表示
“某事本应该发生而没有发生”。
eg：He was supposed to arrive at six. But he was late.
他本应该6点钟到达，但是他迟到了。
The train was supposed to arrive half an hour ago.
火车本应在半小时之前到达。考向四 be supposed to后面接“have＋过去分词”时，表示“本应该做某事而没有做”。
eg：You are supposed to have handed in your
homework.
你本应该把你的家庭作业交上来了。
He is supposed to have arrived an hour ago.
他本应该一小时前就到了。【难点】考向五 suppose，think，believe，guess等可以
在特殊疑问句中作插入语。
eg：Who do you suppose will win the game?
你认为谁将会赢这场比赛？【难点】(二)It＋be＋adj.＋to do sth.句型考向一 It＋be＋adj.＋to do sth.意为“做某事是……的”，it为形式主语，真正的主语是后面的动词不定式(短语)。因动词不定式(短语)作主语较长，而谓语部分相对较短，用it代替后就避免了“头重脚轻”的现象。
eg：I think it's important to sleep eight hours a night.
我认为每晚睡8个小时是很重要的。考向二表示“(对某人来说)做某事是……的”，用句型“It＋be＋adj.＋for/of sb.＋to do sth.”，其中sb.为动词不定式to do sth.的逻辑主语。二者的具体用法为：eg：It's hard for me to answer your question.
对我来说回答你的问题很难。
It was foolish of him to go alone.
他单独去太傻了。典例 —Let me help you carry the box，Granny.
—Thank you，Li Lei. It's very nice ________ you
________ me. (钦州)
A．of；to help B．for；to help
C．of；helping D．for；helping【解析】 It's＋adj.＋for/of sb.＋to do sth.“(对某人来说)做某事是……的”,为固定句型；又因句中的形容词nice是描述人的品行的词，故介词要用of。A1．When you go abroad，it _______________ bring your
passport.
2．After class，students ______________ clean the chalk
off ? the blackboard.
3．If you visit the northern coast of Norway during the winter
season，it __________________ pack warm clothes.

clean up 清除干净知识点1eg：Please clean the writing off the paper.
请把纸上的笔迹擦掉。拓展 clean...off为“动词＋副词”型短语，代词作宾语时，只能放在两词中间，名词作宾语时可放在两词之间，也可放在副词之后。
eg：Please clean them off.请把它们擦掉。
I wanted to clean off the black mark.
＝I wanted to clean the black mark off.
我想把这个黑点擦掉。易错提示： knock /n?k/ v. 敲(门)knock作不及物动词，相关短语：knock at/on 敲，knock against 与……相撞，knock down/off 撞倒。知识点2考向一魔法记忆Yesterday，Tom knocked on my door and told me that his car knocked against a big tree and the tree was knocked down.

and ________ my bowls and dishes. (南京)

A．knocked off B．took off
C．showed off D．turned off【解析】本题考查短语辨析。句意：——昨天汤米走过我
的桌子，碰掉了我的碗和盘子。——下次他应该小心。
knock off 撞倒，碰掉；take off 脱掉；show off 炫耀；turn
off 关上。根据He should be careful next time.可知碗和盘
子被碰掉了。故选A。Aknock用作名词，意为“敲击声；敲击”。

有敲门声。考向二take off 脱下(衣服)；(飞机等)起飞；休假eg：It's very hot in the room. Take off your coat.

A．take care B．take place
C．take after D．take off【解析】考查动词短语辨析。take care当心；take place发生；take after(外貌或行为)像(父或母)；take off脱下，起飞。句意：——今天天气热，不是吗？——是的，天气很热。为什么不脱掉你的夹克呢？所以答案选D。Dtake的常用短语：
