【学法指要】

单元难点疑点思路明晰

1. I\'ve got some personal affairs that I have to see to . 我有些私事非处理不可。

〖明晰〗1) affair, business 作“事物”讲时，这两个词的意义很相近，常可通用。

Mind your own affairs (business) . 少管闲事。

business不能用复数，而affair特别是指重大或头绪较多的事务时，常需要复数，在下面的句子里，这两个词不能通用。

Each Ministry of Foreign Affairs lodged a protest with the other . 双方外交部向对方外交部提出抗议。

Business before pleasure . 先办正事，再谈娱乐。

2)see to有“注意，照料，保证，修理，诊治”等意思。例如：

Your shoes need seeing to . 你的鞋得修补了。

You ought to have your eyes seen to by a doctor . 你应该请医生治眼睛。

2. I dare say my uncle will . I have no other relatives . 我认为我叔父会得到这笔钱，我没有其他的亲戚。

〖明晰〗1)I dare say 的意思并不是“I dare to say”，而是和“也许”几乎同义或者等于“我想”。

I dare say you\'re right . 我看大概是对的。

I dare say it will come later . 我想它以后会来的。

2)dare用作情态动词时，后接动词原形，主要用于疑问句和否定句或者表示不肯定意义的各种从句中。例如：

Dare you ask him ? 你敢问他吗?

I dare not go there . 我不敢去那儿。

That is as much as I dare spend . 我只敢花那么多的钱。

3)dare作主动词时是规则动词，用法如下：

a)表示“敢”，后接动词不定式，也可省去to。例如：

I don\'t know how he dares to appear in public .

I\'ve never dared go back to look . 我从来不敢回去看一下。

3. I think it will be necessary for me to pay you a visit and see where you live . 我想有必要去拜访你，看看你住在什么地方。

〖明晰〗1)句中的it用作形式主语。例如：

Is it necessary for us to meet/necessary that we meet ?我们有见面吗?

2)pay a visit (to someone or something)/pay (someone or something) a visit表示“(短时间)访问(某人，某物)”;“参观(某物)”。例如：

Shall we pay your brother a visit this afternoon ?

4. Do you see that hole high up in the wall, about 18 cm by 9 ? 你看到墙壁上方那个大约18厘米宽，9厘米高的洞没有?

〖明晰〗1)句中的high用作副词，指的是高矮;而highly表示很高的程度(意思往往是 very much)。

The plane flew high above . 飞机高高地在上空飞。

An eagle circled high overhead . 一只鹰在头上高高盘旋。

The goods on display are all very highly priced . 这些展销货物标价都很高。

He speaks very highly of the boy\'s behaviour . 他十分赞赏孩子的行为。

2)about 18 cm by 9用作后置定语，修饰that hole，介词by表示面积、 体积的长、宽、高。例如：

The room measures fifteen feet by twenty feet . 房间宽十五英尺，长二十英尽。

5. Dr Watson and I will spend the night locked in your room . 我和华生就锁在你的房间里过夜。

〖明晰〗1)第一人称单数I与其他人连称用时，通常的词序是，第二、三人称代词在前， 第一人称代词在后。例如：

You and I can do it . 我和你都能做这件事。

You, Tom and I are to leave tonight . 我、你和汤姆今晚得离开。

2)句中的过去分词locked用作方式状语。例如：

Just then the old man entered (supported) by his son . 就在这时， 老人由儿子扶着走了进来。

He turned away (disappointed) . 他失望地走开了。

She went home (exhausted) . 她回到家时已精疲力尽了。

6. Immediately Holmes jumped up from the bed and struck a match . 福尔摩斯立即从床上跳起，划燃一根火柴。

〖明晰〗The young lady rushed into the room immediately she heard the noise . 那位年轻的女士一听到响声就冲入房间。

第一例句中的 immediately 用作副词， 表示“立刻， 立即”; 第二例句中的immediately用作副词，表示“一……就……”，类似的说法还有instantly, directly, the moment, the minute, the instant等。例如：

I\'ll go there directly (=as soon as) I have finished my breakfast .

The moment I saw you I knew you were angry with me .
