1)后跟形容词如： You look well/fine/healthy. 你看起来很健康 The teacher looks happy. 老师看上去很高兴 She looks pale. 她面色苍白 2)后跟过去分词如： You look tired; you’d better have a rest. 你看上去很累,你最好休息一下 3)后跟名词如： He looks a nice, honest man. 他看上去是个诚实的好人 4)后跟介词短语等如： He looks in good health. 他看来十分健康 (2)用作不及物动词,意为“看,望,瞧” 1)单独使用时,后不跟介词如： I looked but saw nothing. 我看了,但什么也没看见 Look! Here comes the bus. 瞧!汽车来了 Look before you leap. 三思而后行 2)和at连用如: The teacher is looking seriously at us. 老师正严肃地看着我们 Look at these pictures. How beautiful they are! 看这些画,它们是多么漂亮啊! 3）和其它某些介词或副词连用: look after 照看，照料 look for 寻找 look around 四下环顾；到处寻找 look back on 回想，回顾 look down on 看不起 look forward to 盼望 look into 朝……里面看 look on...as 把某人看作 look out 当心 look over 仔细检查；翻阅 look through 浏览；仔细检查；看穿 look up 抬头看；查；找出 2. want want 表示“想要”， 有以下用法： ①want+名词“想要某物” I want a bottle of juice. 我想要一瓶果汁。
②want to do sth.“想要干某事” He wants to go to a movie. 他想去看一部电影 ③want sb. To do sth.“想要某人干某事” I want you to play with me. 我想要你和我一块玩 3. be going to （1）be going to 是一种固定结构，它后面要接动词原形，用来表示按计划或安排要发生的动作，有时也可以表示推测将要或肯定会发生的动作，有“准备；打算”的意思含有be going to 结构的句子中往往有表示将来的时间状语如： We are going to have a class meeting this afternoon. 今天下午我们打算开班会安排) Look at the black clouds. It’s going to rain. 看那些乌云，快要下雨了推测) （2）be going to 在肯定句中的形式 be going to 结构中的助动词be很少用原形，它一般有三种形式，即：am , is , are当主语是I时用am；当主语是第三人称单数时用is；当主语是其他人称时用are。
如： I am going to buy something tomorrow morning. 明天早上我要去买些东西 She is going to see Mr. Wang this afternoon. 她打算今天下午去看望王先生 （3）含be going to 的句子变否定句和一般疑问句的变法 由于句子中有助动词be，因此be going to 的否定句和一般疑问句的构成很容易，即在be (am, is, are) 的后面加上not 就构成了否定句；把be (am, is, are) 放到句首，在句末加问号就构成了一般疑问句，其答语为：Yes, 主语+ am/is/are. / No, 主语+ isn’t/aren’t. / No, I’m not.不过 I am... 在改为一般疑问句时常常改为“Are you ....?”如： They are going to see the car factory next week. (肯定句) They are not going to see the car factory next week. (否定句) —Are they going to see the car factory next week? —Yes, they are. (No, they aren’t.) (一般疑问句及其回答) (4)使用be going to 应注意的两点 ①There be 句型的be going to 结构为：There is / are going to be... (注意句型中going to 后面的be不能改为have。
) 常用来表示将有某事发生如： There is going to be a football match next Saturday in our school. 下周六我们学校将有一场足球比赛 ②come, go, leave, arrive等表示位置移动的动词常用现在进行时表示将要发生的动作，它们很少与be going to 结构连用如： Miss Sun is coming tonight. 今晚孙小姐要来 4. be able to be able to do 和can 的含义基本相同，但二者有一定的区别 表示“能力”时，can常指现在，较be able to更常用；如果只表示能力时，两者都可用；但若表示过去的能力+特定行为时，则要用was/were able to；若指将来才具备的能力则只能用shall/will be able to表示如： I can/am able to swim. (现在时，二者皆可) 我会游泳 The baby will be able to walk in a few weeks. (表示将来的能力，不能用can) 这个婴儿几周后将能走路。
5. sure 我相信李先生一定会感到惊讶和快乐 sure 是形容词，意为“肯定的，当然的”常用来回答一般疑问句，等于 Yes或Certainlysure的用法： (1)be sure＋不定式常用于祈使句，表示要求，意为“务必、请一定”指外界的看法如： I think he’s coming, but I’m not quite sure. 我认为他就要来了，但我不是很肯定 Be sure to telephone me and give me all the news. 务必打给我并告诉我所有消息 (2)be sure＋of或about意为“相信，对……有把握”，后接名词、代词或动词的-ing形式常用来表示“人对某事的看法”，指主观上的看法如： Are you sure of that meeting? 你相信那场会吗？ He is sure about this answer. 他对答案很有把握(胸有成竹) (3)be sure＋从句表示“某人对……有把握”如： I’m sure that he is coming to help me. 我相信他会来帮我的。
The teacher is sure that these books are interesting. 老师很有把握地说那些书非常有趣 (4)make sure意为“务必、确信”，其后也可接of或about或动词不定式或that从句如： I made sure (that) he was badly ill. 我确信他病的很严重 Will you make sure of his return? 你能确保他返回吗？ Make sure to come to the party on time. 务必准时到晚会来 6. be popular with somebody popular 形容词 流行的, 受欢迎的 a popular song 一支通俗歌曲 She is popular at school. 她在学校里很受人喜欢 如果表示“受某人的欢迎，在某人中流行”，用短语：be popular with somebody,如： This dance is popular with young people. 这种舞很受青年人喜爱 7. deal with的用法 (1)dea。
