Unit 3 Computers 教案之语言点详解

词汇详解:

一.

词语辨析 1. personal / private / individual

【解释】

personal 指属于或关于某人或某些特定的人,以区别于其他人。

private 指属于私人所有或具有私营性质,以区别于集体或公共的,有时含不公开的意味。

individual 与集体的相对,指个别或个体的。

【练习】用上面所提供的辨析词的适当形式填空

1). Will you do it for me as a ________ favour?

2). If you go to a _________ hospital,

you must pay. 3). We traveled together,

but each _________ bought his own ticket. Keys:

1). personal

2). private

3). individual

2. after all/above all/at all/in all

【解释】

after all意为“毕竟”“尽管”“到底”“究竟”;

above all 意为“最重要的是”“尤其是”;

at all一般用在否定句中,用以加强否定语气。at all用在疑问句、条件句中,起强调作用,意为“真的”“确实”“竟然”等。另外,not at all用来表示“不用谢”;

in all表示“总共”“总计”。

【练习】用上面所提供的辨析词的适当形式填空

1). So you see,I was right ________.

2). ________,he wanted to succeed.

3). It will do you no harm ___________.

4). We visited,

_______,

20 universities in the US.

Keys: 1). after all 2). Above all

3). at all

4). in all

3. type / kind /sort 【解释】

1)kind系普通用语,其含义较模糊,它所指的种类可用任何标准区分,但着重以事物的自然属性和内在性质为标准来区分。

2)type常和换用kind,但在表示动植物的种类,以及牌类游戏时,不能用type代替

3)sort也为普通用语,比kind更口语化,其概念同kind一样很不严密,两者常可互换,

但sort常掺杂说话人的主观色彩,带有轻蔑与贬低的含义。如:

We talked of all sorts of subjects.我们谈了各种话题。

These sorts of people are ready to eat anywhere.这种人总是走到哪里吃到哪里。

【练习】用上面所提供的辨析词的适当形式填空

1). He’s quite a pleasant ________,

really. 2). All ________ of difficulties have to be overcome. 3). I’ll never do this _________ of thing.

4)There are different ________ of animals in Shanghai Wild Animal Park. Keys: 1). type 4.deal with/do with 【解释】

deal with和do with二者可译为“处理”,但在特殊疑问句中,

do with与what配合使用,而deal with与how配合使用。

【练习】用上面所提供的辨析词的适当形式填空

1). How would you _________ an armed burglar?

2). What have you __________ my umbrella?
