1. Struggling in a world of silence and darkness, I must have appeared to them to be simple. 我掙扎在一個聽不到聲音、看不見天日的世界里,對他們來說,我準(zhǔn)顯得頭腦簡單。

1) world表示"世界"時,通常在其前加定冠詞the;但world前面或后面有定語修飾時,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表示對過去的一種肯定推測,意思是"肯定","準(zhǔn)是"。例如:

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

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

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(jié)構(gòu)常有以下用法:

1) 常用來表示計劃或安排(做某事)的意思。例如:

We are to begin the work next month.我們安排下個月開始這項工作。

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.辦公室沒有人的時候,你可以讓留言機(jī)開著,以便給你打電話的人可以留言。

本句中兩次出現(xiàn)了leave,第一個leave后接復(fù)合賓語,是"使......處于(某種狀態(tài))"的意思;第二個leave是"把......交給;委托"的意思,短語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(dāng)長的時間去把那根長長的橡皮管接到環(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(qū)別是:

1) can沒有將來時、完成時等,這種情況下用be able to表達(dá)。

2) 表示"過去成功地做了某事"時,不可用could,應(yīng)使用was (were) able to來表達(dá)。本句中的was able to就不能用could替換。
