【课文分析】

    1.He became interested in flying ever since he took his first flight at the age of six.

    ①become interest in 开始对……感兴趣。

    We have become interested in science.

    我们开始对科学感兴趣了。

    和interest有关的短语还有:

    show interest in sth.(interest是名词)表现出对……的兴趣。如:

    My son is already showing an interest in music.

    我儿子已经表现出对音乐的兴趣。

    be interested in对……感兴趣。如:

    Are you interested in football?

    你对足球感兴趣吗。

    ②at the age of 在……岁时

    He can’t understand such a thing at the age of ten.

    在他10岁时,他不明白那样的事。

    I began to learn English at the age of six.

    我六岁时开始学英语。

    2.In his spare time, he built model aeroplanes and wind tunnels to test the model aeroplanes.

    spare 作形容词时意为“空闲的”

    in one’s spare time 在某人的空闲时间。如:

    What does Amy usually do in her spare time?

    艾米在业余时间里一般做什么呢?

    spare 作动词时意为“让给,腾出”。如:

    Can you spare me five minutes?

    你能腾出五分钟和我谈谈吗?

    3.Armstrong studied engineering and later joined the navy in 1949.

    ①later“后来,之后”

    Later he decided to taste the hot mixture.

    后来他决定尝一下这种热的混合物。

    I’ll give you further details later.

    我以后会告诉你更多的细节。

    ②join “加入”

    Do come and join us.

    一定要来参加我们的活动。

    Xiao Ming is old enough to join the army.

    小明到了参军的年龄。

    4.He worked as a naval pilot for three years.

    ①句中的as是介词,表示“作为”。如:

    What do you do every day as a librarian?

    作为图书管理员,你每天都做什么?

    She has worked as a cleaner in this hospital for 5 years.

    她在这家医院作清洁工五年了。

    I wrote on the ground with a stick as a pen.

    5.In 1962, he was selected to become an astronaut.

    select“挑选,精选”

    Four skiers will be selected to represent each country.

    每个国家将选出四名滑雪者作为代表。

    辨析:choose, select, pick

    这组动词都有“挑选”的意思。

    ①choose 强调在“选择”某物时的意愿,特别是当供挑选物只有两个时,我们应当用choose。如:

    I am not sure which sweater I should choose.

    我不确定我应该选哪一件毛衣。

    ②有好几个东西供选择时,最好用 select。因为有较多的被挑选物,挑选人就必须加以鉴别。如:

    ③pick 在用作“挑选”时,不强调鉴别,也不强调意愿。

    Tom picked a red shirt because he liked red.

【语法讲解】

    A.限制性定语从句

    定语从句有限制性和非限制性两种。

    关系代词或者关系副词所引出的定语从句如有限定或确定先行词的作用,即为限制用法。限制性定语从句是先行词不可缺少的定语。对句意的明确性起着重要的作用。如果省去,往往会使主句的意思不完整、不明确。由于这种不可分的特点。故在使用中不用逗号隔开。

    The woman who is wearing a red dress is Mrs Green.

    那个穿红礼服的女人上格林夫人。

    The city where I live is beautiful.

    我居住的城市很美丽。

    We shouldn’t eat fruit that are green

    who is wearing a red dress ,where I live, that are green 这些是分别是这3个句子的定语从句,去掉它们句子的意思就不完整了。

    B.关系代词

    在复合句中修饰名词或代词的从句叫做定语从句。被定语从句修饰的名词或代词叫做先行词。引导定语从句的词称为关系词,有关系代词和关系副词两类。在本单元中,我们只涉及到关系代词。

    引导定语从句的关系代词主要是who/whom/whose/that/which。关系代词在句子中所能作的成份,如下表所示:

    1) who引导,修饰前面指人的名词或代词,做该定语从句的主语。如:

    He who doesn’t study hard won’t pass the exam.

    谁不认真学习他就考试及格不了。

    Do you know the young woman who is talking with Jim?

    你认识那个正在和吉姆说话的年轻妇女吗?

    2) whom引导,修饰前面指人的名词或代词,作该定语从句的宾语,whom在定语从句中可以省略。

    Do you know the young woman (whom) Jim is talking with?

    你认识那个吉姆正在和她讲话的年轻妇女吗?

    3) whose引导,其修饰的词可以是人也可以是物,在从句中whose作其后接名词的定语

    This is the famous singer whose songs are popular all over the world.

    这就是那个歌曲在全球流行的著名歌手。

    Every morning I go to the park whose gate is never locked.

    每天早晨我都去那个从不关门的公园。

    4) that引导,可指人也可指物,在从句中可以作主语或宾语,作宾语时that可省略。

    That is the only movie (that) I’d like to see.

    那是我唯一喜欢看的一部电影。

    5) which引导,可指人也可指物,在从句中可以作主语或宾语,作宾语时which可省略。
