1. Struggling in a world of silence and darkness, I must have appeared to them to be simple. 我掙扎在一個(gè)聽(tīng)不到聲音、看不見(jiàn)天日的世界里,對他們來(lái)說(shuō),我準顯得頭腦簡(jiǎn)單。

1) world表示"世界"時(shí),通常在其前加定冠詞the;但world前面或后面有定語(yǔ)修飾時(shí),通常要用不定冠詞a。

Wouldn't it be ________ wonderful world if all nations lived in ________ peace with one another?

A. a; / B. the; / C. a; the D. the; the

答案:A

2) must have appeared表示對過(guò)去的一種肯定推測,意思是"肯定","準是"。例如:

It must have rained last night, for the ground is wet.昨天晚上肯定下過(guò)雨了,因為地面還是濕的。

對過(guò)去的否定推測不能用"mustn't + have + 過(guò)去分詞",而應使用"can't (couldn't) + have + 過(guò)去分詞"。

2. Those first words were to change my world.我最先學(xué)的這些單詞改變了我的生活天地。

"be + 不定式"結構常有以下用法:

1) 常用來(lái)表示計劃或安排(做某事)的意思。例如:

We are to begin the work next month.我們安排下個(gè)月開(kāi)始這項工作。

2) 表示注定要發(fā)生的事。例如:

This experience was to change his life.這次經(jīng)歷注定要改變他的生活。

3. When there is no one in the office, you can leave the answering machine on so that people who call you up can leave a message.辦公室沒(méi)有人的時(shí)候,你可以讓留言機開(kāi)著(zhù),以便給你打電話(huà)的人可以留言。

本句中兩次出現了leave,第一個(gè)leave后接復合賓語(yǔ),是"使......處于(某種狀態(tài))"的意思;第二個(gè)leave是"把......交給;委托"的意思,短語(yǔ)leave sb. sth (=leave sth. to sb.)意思是"把某物(事)交給某人"。leave a message的意思是"留言"。

4. It took him some time to connect the long rubber pipe to the air supply pipe that ran round the port, but at last it was done and as a result work was able to progress much faster.他花了相當長(cháng)的時(shí)間去把那根長(cháng)長(cháng)的橡皮管接到環(huán)繞港口的輸氣管上,但最后還是接好了,因此,修理工作進(jìn)展得快多了。be able to一般可與can互換使用,其區別是:

1) can沒(méi)有將來(lái)時(shí)、完成時(shí)等,這種情況下用be able to表達。

2) 表示"過(guò)去成功地做了某事"時(shí),不可用could,應使用was (were) able to來(lái)表達。本句中的was able to就不能用could替換。
