Unit_1Willpeople_have__robots知识点讲解及其练习(好资料).doc

1、Unit 3 Will people have robots?1、一般将来时a) 一般将来时的构成：由助动词shall或will加动词原形构成，shall用于第一人称。在口语中，will在名词或代词后常简略为ll， will not常简略为wont。这个时态的肯定，否定和疑问结构可表示如下：肯定句否定句疑问句I (We)shall(will) go.You(He, She, They) will go.I(We)shall(will) not go.You(He, She, They)will not go.Shall I(we) go?Will you (he, she, they) go?

2、用”be going to +动词原形”也可表示将来时，表示将要发生的事，打算或决定要做的事。I think it is going to snow.我看要下雪。b)一般将来时的用法：1）表示将要发生的动作或情况；2） 不以人的意志为转移，肯定要发生的事情。The day after tomorrow will be National Day.后天是国庆日。 c) 一般将来时的时间状语标志词：1.含tomorrow; next短语；2.in+段时间 ；3.how soon；4.by+将来时间；5.by the time sb.do6.祈使句句型中：or/and sb. will do7.在时间

3、/条件状语从句中, 如果从句用一般现在时, 主句用将来时 8.another day 2、in 与 after的区别in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”，句子中的谓语动词要用一般将来时态；after常指以过去时间为起点的“一段时间之后”，所以它与过去时态连用。当after指某个特定的未来时刻或日期之后，或指以将来某一时间为起点的若干时间之后时，它可以与将来时态连用。 例句：Ill be back in half an hour. 我半小时后就回来.本句中的in作以后解，不能用after代替。after和in都可以表示以后的意思，其区别是：1）after

4、以过去为起点，表示过去一段时间以后，常用于过去时态的句子。例如：They started working after lunch. 他们是午餐后开始工作的。The film was shown after the meeting. 电影是会议结束以后放的。2）in以现在为起点，表示将来一段时间以后，常用于将来时态的句子。如：They will start working in half an hour. 他们将在半小时后开始工作。The film will be shown in 2 or 3 days. 这部电影将在两三天后上映。3）在某个特定的时间以后，after也可用于将来时态的句子。例

5、如：They will start working after 10 am. 他们将在上午10点以后开始工作。The film will be shown after 5 oclock. 这部电影将于4点以后上映。4) “after+一段时间”或“一段时间+later”表示“（在过去某个时间看来）一段时间之后”。He went home after two days. 他两天后回家了。Three years later，she had a baby. 三年后，她生了一个婴儿。征对性练习一. 根据句意，用括号中动词的适当形式填空。1.

9、ays more than one hundred birds in the big tree every evening. 每天傍晚那棵大树上总会有100多只小鸟。一、There be句型的用法:1)There与be中间可插入一些表示推测的情态动词、表示时态的短语和一些动词短语,以强调某种语气。例如:There must be some flowers in the box. 盒子里肯定有些鲜花。There happened to be some money in my pocket.我的口袋里碰巧有一些钱。There will be a meeting this afternoon.注意:

10、be不能换成have及have的变化形式。2)There be句型常与过去时间状语连用,构成一些固定句型,用于故事发生的开头,交代故事发生的时间。例如:Many years ago,there was such a beautiful girl called Cindy.很久以前有一个叫Cindy的美丽女孩。3)There be句型可换成There come / go,以引起注意,加强语气。例如:There comes the bus.公共汽车来了。4)There be句型或There加其他动词的句型,其动词的单复数,常采用就近一致的原则。例如:There is a desk, two cha

11、irs and three benches in the room. There are two chairs, a desk and three benches in the room. 5)There be或There加其他动词的句型,其反意疑问句一律用there？ 例如:There is a cat in the garden, isnt there？ There used to be no house here, used there / did there？(过去这儿没有房子,是吗？)二、使用There be句型时应注意:1、there be 结构中的be是可以运用各种时的。 The

12、re is going to be a meeting tonight.今晚有个会议。 There was a knock at the door.有人敲门。 There has been a girl waiting for you.有个女孩一直在等你。 There will be rain soon.不久天就要下雨了。 2.动词be单复数形式要跟there be之后的真正的主语一致。并且要根据就近一致原则来变换be的单复数形式。如：There is a book on the desk.课桌上有一本书。 How many people are there in the city?这个城市里

13、有多少人口。There is a pen and two books on the desk.课桌上有一个钢笔和两本书。3. 在therebe引起的句子结构中，用来修饰主语的不定式主动形式和被动形式均可。 There is no time to lose(= to be lost).时间紧迫。 There is nothing to see(=to be seen).看不见有什么。 There is nothing to do.(=to be done)无事可做。 4、There is no doing.（口语）不可能.There is no telling when he will be b

14、ack. 无法知道他什么时候回来。There is no knowing what he is doing. 无法知道他在做什么。 4、.there be与have的区别：1）含义不同。there be表示的是“某地（时）有某人（物）”，强调“存在关系”。Have则表示“某人（物）所有”，强调“所属关系”。如，There is a bus in your factory.（公共汽车不一定属于我们厂所有） Our factory has a bus.（公共汽车属于我们厂所有）2）句型不同。there be句型为“There be +某人（物）+某时（地）”；have 句型为“某人（物）+have

15、(has)+某物（人）。如There isnt a cat under the chair. She doesnt have two brothers.3)当表示某物的构成和组成部分时，用there be和have 均可。如，Our school has sixty classes.= There are sixty classes in our school.我们学校有60个班。【注意】there be句型中有两个或多个并列主语时，须根据就近原则，be与最靠近的主语在数上保持一致。如，There are two eggs and a cup of milk on the table.Ther

23、6点起床。He wears everyday clothes today今天他穿一身便服。Wear、put on、have.in的区别wear表示“穿”，表示状态，用一般现在时表示经常状态，用现在进行时表示暂时状态。egWe wear our rain boots on a rainy day. 我们在下雨天穿雨鞋。She is wearing a new coat 她穿着一件新衣服。Does he wear glasses? 她戴眼镜吗？put on是“穿上”，“戴上”的意思，强调动作。egShe put on a red coat and went out. 她穿上红色大衣出去了。 注意：

24、put on是一时的动作，不能跟表示一段时间的状语连用。他整天戴着草帽。 误：He puts on a hat all day. 正：He wears a hat all day5、. be worth doing值得；be worthy of doing, be worthy to do值得6、Seem的用法：1)seem to do似乎He seems to think so.2)It seems that看来It seems that he is lying. 3) seem +adj./n.好象是 He seems ill.7、would like sth意思为“想要某物“； woul

25、d like to do意思为 “想要做某事”。回答would like句型的一般疑问句时，其肯定回答为 “Yes, please.”;否定回答“No, thanks”或 “Id like /love to, but.”8、.make sb. do; make +n+adj.; make friends with sb.; make +n./ pron.+n.9、. Such作形容词，意思是“如此的”“这样的”，修饰各种名词。 Such这样的。如It is such bad weather.天气如此恶劣。 Such常和as搭配，表示一种类别。如We enjoy such a voice as

26、hers.我们喜欢象她那样的嗓子。 Such常和表示结果的that从句搭配，表示“如此.以至于”如 It was such a hot day that we all had to stay at home. Suchthat和sothat都可用来引出一个结果状语从句。由于such是形容词，所以that从句前有一个受such修饰的名词；而so 是副词，用以修饰形容词或副词，因此that从句前一般不出现名词。如 They are such kind-hearted teachers that people in the village all respect them. The exam was

27、 so difficult that many students failed to pass it.a) 如果名词是可数名词的单数形式，such和so的位置不同：such+a/an+形容词+单数名词so+形容词+a/an+单数名词b) 如果名词是不可数名词或名词复数，只可用such,不能用so.:such+形容词+不可数名词或复数名词c) 如果被修饰的不可数名词被much, little, 或复数名词被many, few等表示量的形容词修饰时，用so，不用such.d) 当little表示“年纪小的”时，可用such+little+名词 There were such little chil

28、dren that they couldnt clean the room.10、 people, person, folks, human: people“人们“全体；person “人”（不分年龄，性别它包括men, women, children.它可做people的单数形式可以说every person但不能说one people. Person指“人们”时着重个体；folks“人们”，指一般人或特殊年龄位置，境遇等特殊级的人；human主要用来区别于其他动物。11、be able to 为“能，会”，表示能力，在这个意义上与can的意思相同，一般情况下两者可以互换，但can只有现在式

29、和过去式（could）而be able to则用于更多的时态，主要体现在be的变化。两者在用法上有一些差异：can （could）表示主观能力不表示意愿，它的将来时用will be able to而 be able to表示主观意愿强调克服困难做某事。12Fee-fed-fed. Feed sth to sb把食物给;feed sb on sth13.use的短语： (1)be used by:被使用 e.g. Rockets are used by astronauts. (2)use sth. to do sth.:使用某物做某事 e.g. He often uses the comput

33、 to you. 3.表示过去习惯性的动作，着重动作的重复，有“总是、总会”等意思。例如： On Sundays he would come to our village and work with us. 4.表示虚拟、假设、条件等，有“要、将要、会、就会”等意思。例如 1） If you had come earlier ，you would have seen him. 2） It would be better to adopt the new method. 注意： 1）would like； Would like to do = want to 想要，为固定搭配。 Would yo
