二、本单元课文难点讲解
第69课重点例句及相关知识的分析
1. Well, first I was so busy reading a novel that I forgot to look at the time.
句中be busy dong sth是"忙于做某事"，而be busy with sth 则是"忙于某事"的意思。forget的过去式为forgot，过去分词为forgotten，其后的宾语可以由不定式充当，也可以由动词的-ing形式来充当，但两者的意思是有区别的。forget to do sth是"忘记做某事"，此事还未做；forget doing sth是"忘记了做过某事"，此事已做过。
例如：（l）Don't forget to post the letter. 不要忘了寄出这封信。
（2）He has forgotten to pay me． 他忘了付钱给我。
2. He said he was coming.
... he was coming.过去将来时，表示过去计划安排要做的事情。
如：Did he know when and where we were meeting?
3. I'm beginning to get angry with him．
get在本句中当系动词，后跟形容词作表语。意思是"变为……；变得……"。需要注意的是 get angry with与 be angry with虽然汉语意思相同，但前者更强调"由不生气变得生气了"这一过程。例如：
（1）Spring comes, it gets warmer and warmer．
（2）I hope you will get better soon．
4. We can't wait any longer.
not any longer 不再
如：I can't wait any longer.
He doesn't live here any longer.
not any longer=no longer
如: He lives there no longer.
She no longer needed the shoe!
5. That's really a bad excuse.
excuse
(1) vt. 原谅
如：Excuse me , may I use your bike?
Excuse me for coming late.
(2) n. 借口，托辞，理由，辩解
如：Her excuse was that her watch had stopped.
What is your excuse for failing to hand in your homework?
What is your excuse for being absent?
He made an excuse for being late.
6. Now we need to wait for Jim．现在，我们须等等Jim。
need既能作名词，亦能作动词，意思是"需要；必须"。
need既能作情态动词，也能作规则动词。need解释为规则动词的"需要；要"时，相当于want，need+ V-ing = need to be + V - ed
例：It needs rewriting. = It needs to be rewritten. 它需重写．
need解释规则动词的"必要"时，相当于be necessary，通常限用于疑问句及否定句中。
need作情态动词时，相当于must，但语气较弱些。
第70课重点例句及相关知识的分析
1. mist n. 雾，其形容词为misty，比较级为mistier，最高级为mistiest。
例如：（l）The accident happened on a misty evening.
（2）She is lost in the mists of time．
（3）The distant trees misted over.
2. Mallory was an English school teacher who loved climbing．
句中who是关系代词，引导的是定语从句，用来修饰前面的先行词teacher。同时，who在定语从句中作主语。因此，不可以省略，可由that来替换。
例如：（1）I didn't see the man who/that stole my bag．
（2）Most people who/that live in less developed countries are quite poor．
3. … but some people wondered whether Mallory and Irvine had got there first．
本句是带有宾语从句的复合句，主句使用了一般过去时态，从句使用的是过去完成时，说明从句的动作在主句的动作之前完成的。wonder用作动词，是"想要知道"的意思，常跟宾语从句。同时它还有"感到惊奇"之意。
例如：（1）I don't wonder at her refusing to marry him．
（2）I wondered to hear her voice in the next room.
（3）I wonder what she wants．
（4）I was wondering how to get there quickly．
4. The other members of their climbing team watched as Mallory and Irvine climbed slowly up towards the summit. 登山队的其他成员看着Mallory和Irvine向着峰顶缓慢地攀登着。
（l）climbing team登山队。climbing在这里是动名词，表示目的。所以，climbing team＝team for climbing
动名词作定语的其他例子：
walking stick = stick for walking拐杖；sleeping bag = bag for sleeping睡袋；swimming suit = suit for swimming泳装。
（2）as在这里等于when／while。
（3）towards = toward（介词）朝……的方向，但不一定到该处。
to有时相当于towards，但有时有"到"该处的含义。
5. However, it is still not known whether he and lrvine ever reached the top of the mountain.
it is known+从句，是一个常见的句型。
如：It is well known that China is famous for the Great Wall.
it is said that.... 据说；it is reported that...据报道; it is told that...据告知……。
三、本单元词语辨析
1. before long, long before
before long的意思是"不久以后，很快"用于将来时态。而 long before意为"很早以前"，用于过去时。例如：
（1）I hope to see you again before long．
（2）We finished our work long before．
2. so that....; so... that....
(1) so that....为了，以便 。引导一个目的状语从句，从句中往往有情态动词。也可引导一个结果状语从句。
如：I left at 5:00 so that I could catch the early bus.
Speak loudly, so that they can hear what you say.
He didn't study English so that he lost a chance to work in a foreign company.
(2) so... that....既可引导一个结果状语从句，也可引导一个目的状语从句。
如：The classroom was so noisy that I could hardly study.
I got up so early in the morning that I could catch the train.
四、同步练习

1. The box is too heavy for me to carry. (改为同义句))

2. Where will they spend their summer holidays next year? She didn't know. (改为含有宾语从句的复合句)

3. "Have you returned the books to the library?" she asked me. (改为含有宾语从句的复合句)

同步练习答案及讲解
