课文详注 Further notes on the text

1.I often fish for hours without catching anything. 我经常一钓数小时却一无所获。

without 通常表示“缺乏”、“没有”:

当它位于动名词前时,它表示“不曾”、“不”:

杰克代替托尼参加了比赛。

Instead of sugar, he bought some salt.

他没有买糖,而是买了些盐。

副词instead单独使用时一般出现在句尾:

If you don't want a holiday in England, why don't you go to Australia instead?

假如你不想在英国度假,那你为什么不去澳大利亚呢?

3.I am even less lucky. 我的运气甚至还不及他们。

less是little的比较级,意为“不及”、“不如”、“更少”:

Tom has got little chocolate, and Jack has got even less.

汤姆只有一点儿巧克力,杰克则更少。

I spend less time on English than on French.

我花在英语上的时间比花在法语上的少。

(cf. 第8课语法)

4.…I always go home with an empty bag. ……然后空着袋子回家。

with可以表示“有……的”、“持有……的”、“随身带着……”等:

Who's the man with the umbrella?

Who's the man with the beard?

那个留胡子的男人是谁?

Who's the woman with the little boy?

带着那个小男孩的女人是谁?

5.I'm not really interested in fishing. 我并不是真的对钓鱼有爱好。

语法 Grammar in use

动名词(The Gerund)(1)

动名词和现在分词的形式完全一样,都是由动词+-ing构成。-ing 形式作名词时称为动名词。从广义上讲,动名词可以代替名词,尽管它像动词一样可带宾语。像名词一样,它可以作主语:

Dancing is fun. I love it.

跳舞有意思,我喜欢跳舞。

Walking quickly is difficult.

走快是很难的。(动名词+副词作主语)

Washing the car makes him dirty.

擦洗汽车把他身上弄脏了。(动名词+宾语作主语)

动名词也可以作宾语或介词宾语:

Mary is keen on cooking.

玛丽热衷于烹调。(介词宾语)

Congratulations on passing your exams!

祝贺你通过考试!

可以带动名词的介词通常有 before,after,instead of,without 等。用介词+动名词结构可以将两个短句合为一句话,或者将一个从句变为动名词结构。动名词的否定式是在它前面直接加not:

Tom always knocks before entering a room.

汤姆在走进一个房间前总要敲门。

He apologized for not writing to you.

他为没给你写信而表示道歉。

动名词也可以用表示完成时的 having +过去分词结构:

You can't leave the restaurant without having paid the bill.

在没有付账之前你不能离开饭店。

I an did not understand English.

伊恩不懂英语。(不可用 realize)

3.interested与interesting

大多数现在分词和许多过去分词都可以作形容词用。常见的以-ed和-ing结尾的成对的形容词有 excited/ exciting, tired/ tiring, interested/ interesting等。以-ed结尾的形容词常与人称主语连用,表示人的情绪、状态、喜好等;以-ing结尾的形容词则常与非人称主语连用,表明事物的某种特征、性质等:
