【重点难点】

   1.Mr. Jiang is the first person in Sunshine Town to own a robot.

    to own a robot  是不定式短语做定语,修饰 person。e.g.

    Have you had enough to eat?

    辨析in order to / in order that

    (1)in order to +动词原形

    否定形式:

    in order not to do sth.

    The assistant told the students to keep quiet in order not to disturb others.

    (2)in order that 后接从句,表示目的,从句中常用may, can, could, might, will be able to, would, should 等情态动词。

    He spoke slowly in order that everyone could understand him.

    4.The robot made Mr. Jiang's life much easier.

    机器人使得姜先生的生活变得更加轻松。

    make + 宾语+ 形容词做宾语补足语,其中宾语补足语可以用名词、形容词、动词的过去分词或省略to的不定式等,以表示宾语的情况或动作。

    He was a little man with thick glasses, but he had a strange way of making his class lively and interesting.

    他戴着深度近视眼镜,身材瘦小,但他有一套可以使他的课生动,有趣的奇妙方法。

    Your letter made me very happy.

    你的来信使我很高兴。

    He raised his voice to make himself heard.

    夜深了,又没有公共汽车,结果我们只好步行回家。

    He has broken his leg. As a result,he will have to be away from school for two or three months.

    他把腿摔断了,因此他将不得不休学两三个月。

    as a result之后还可以加of结构,即:as a result of,意为:由于……的结果。

    由于从自行车上摔下来,他不能去上班了。

    As a result of his hard work,he received a big prize.

    由于他工作勤奋,所以获得了大奖。

    (2)no longer  不再,相当于 not any longer  上句也可写成:

    …Mr. Jiang did not need to get up early to do the housework any longer and he … .

    an extra hour = one more hour = another hour 表示“在原来的基础上再加一小时”。

    辨析no more 与not …any more

    二者都表示“不再”,“再没有”的含义

    7.While Mr. Jiang was at work, the robot would clean his flat.

    当姜先生在工作的时候,机器人就在打扫他的公寓。

    at work的意思是“在工作”。at是介词,表示人和事物的状态。work作“工作”解时,是不可数名词。此外,在短语前,往往带be动词,即be at work.例如:

    1)—Where is your father?  你父亲在哪儿?

    —He's at work.  在上班

    2)Is your mother at work now ? 你母亲现在在上班吗?

    类似的短语还有:

    be at home 在家       be at school 在上学

    e.g. He had gone wrong and made many mistakes.

    My computer has gone wrong. It doesn't work.

    11.Mr. Jiang did not know what he should do with the robot.

    do with 与what 连用,表示“对待、处理”,表示“怎样处理某事”要说“what… do with…”,不说 “how… do with…”。

    e.g. I don't know what to do with the rubbish.

    What have you done with the milk?

    12.The robot was just too much trouble. 

    机器人真是太麻烦了。

    too much“太多”,修饰不可数名词或动词;

    e.g. too much time; too much money; eat too much

    too many “太多”,修饰可数名词的复数形式。

    e.g. too many books; too many people

    much too  “太”,修饰形容词或副词。

    e.g. much too expensive; much too late

    13.Will a robot bring any bad changes to your life?

    机器人将给你的生活带来坏的变化吗?

    bring sb. sth. = bring sth. to sb.  “给某人带来某物”

    14.What can you do if you decide that having a robot is too much trouble?

    如果你确定拥有一个机器人太麻烦,你该怎么办?

    that having a robot is too much trouble 为宾语从句,做decide的宾语。having a robot 在宾语从句中做主语。

    e.g. We know that going to bed late is not good for our health.

Vocabulary

    1.My robot is made to look just like a real person. 

    我的机器人造的像真人一样。

    be made 是被动语态,“被制造”。主动语态应是:

    I make my robot look just like a real person.

    辨析be made to do sth. / be made of / be made from/ be made in / be made by

    be made to do sth. 被迫做某事

    The workers were made to work 10 hours a day.

    工人们每天被迫工作十小时。

    make, let, have作使役动词,其后接不带to的不定式作补语,但这类结构变为被动语态时,后面不带to的不定式要转换为带to的不定式。

    be made of 意为“由…原材料制成”,主语为制成品,而且能看出原材料, of后面接表示原材料的名词。

    e.g. This jacket is made of cotton. 这件上衣是棉花做的。

 【新题预测】

    ①The result of the experiment was very good,       we hadn't expected(预料).

    A、when        B、that        C、which        D、it

    【答案】C

    【解析】此句主从句之间有逗号分开,且从句并非主句必要成份,属于非限制性定语从句,应由which来引导,不可用that。

    ②—I drove to Zhuhai for the air show last week.

    —Is that the reason       you had a few days off?

    A、why        B、when        C、what        D、where

    【答案】A

    【解析】reason做先行词,其后定语从句又缺少原因状语,故用why这一关系副词。

    4.The robot also has three long arms connected to its chest.

    机器人还有三只胳膊与它的胸部连接。

    connect to连接;相连

【语法讲解】

   A   本单元主要学习由连接代词或连接副词引导的宾语从句,that 在宾语从句中只起连接作用,没有含义,也不在从句中充当成分,故可省略。但有些词如连接代词 what, who, whom, which 和连接副词 when, where, how, why,它们在从句中既起连接作用,又在句中担当一个成分,所以不能省略。如:

    Nobody knows where she was born.

    没有人知道她是在哪儿出生的。(where 在从句中做状语)

    We don't know who will teach us English next term.

    我们不知道下学期谁将教我们英语。(who 在从句中作主语)

    另外,在运用宾语从句时要注意:

    (1)如果主句时态用过去时,则从句一般也要用与过去相关的时态。如:He knew that he was wrong.(他知道他错了。)

    (2)that 不能和其他连词重复使用,如:

    Can you tell me that what time it is?(误)

    Can you tell me what time it is?(正)

    (3)宾语从句的词序要用陈述句的语序。

    Please tell me how can I study English well.(误)

    Please tell me how I can study English well.(正)

    B  (1)in order to do sth.  是“为了做某事”,是动词不定式作目的状语。in order that从句也是“为了……”之意,是目的状语从句,也可用so that从句来换。

    In order to catch up with his classmates, he works harder than ever.

    为了赶上同学们,他比以往更加用功了。

    The teacher explained the passage again and again in order that every student might understand it.

    老师一遍又一遍地解释这篇文章,以便每位学生都能够理解。

    (2)As a result (由于的)结果;因此常用在有上下文的情况下。例如:

    It was late at night and there was no bus. As a result , we had to walk to He village.

    夜深了,又没有公共汽车,因此我们不得不步行到那个村庄。

    He had some bad fish, As a result, he felt sick his morning.

    由于吃了些坏鱼,所以今天上午他感到不舒服。

    As a result of (=because of… )意思是“由于”例如:

    As a result of fog the flight was delayed.

    由于有雾,航班误点了。

    He got a rise as the result of his hard work.

    由于他工作勤奋,所以他长了工资。

    Thousands of people lost their lives as the result of the war.

    由于那场战争,成千上万的人民丧失了生命。

    (3) In order to keep my flat as clean as new, I had my robot sweep the floor every day.

    have my robot sweep the floor 让我的机器人打扫地板

    have sb. do sth. 使某人做某事,do前省略不定式符号to。与have相搭配的还有:have sth. done表示某事已做了,有三层含义:①表示主语有意识地让别人做某事;②说明主语蒙受伤害、损失;③表示句子的主语可能参与完成的某件事。have sb. done使某人被或受……,have sb. doing使某人做某事,have sth. to do有什么事要做,这种结构中主语是不定式的逻辑主语。

【新题预测】

    C.done

    D.to be doing                                           (答案:B)

    Help should be given to those who need it (need + pron)

    I don't think you need to help him.(need + to do)

    我觉得你没必要帮他。

    Our farm needs helping in autumn.(need+动词-ing形式)

    注意helping虽是-ing形式,但是含有被动的意思。此句还可以用不定式的被动式来表示,即:Our farm needs to be helped in autumn.

    (2)need 可作情态动词,后跟动词原形,作“需要”,“有必要”解,通常用于否定句中。例如:

    (3)need作名词,构成in need of词组,作“需要……”解。如课文中出现的:

    A friend in need is a friend indeed.患难见真情。
