1．I’ll be able to write faster. 我就能写得更快些。
be able to 意思是“能够”，相当于情态动词can，只是can 只有现在式和过去式两种(can. could)，而be able to则有更多的时态形式。例如：
Some of us can use the computer now. But we couldn’t do it three years ago.
我们中有些人现在能使用计算机，可在三年前我们就不能。
The work is so difficult. No one is able to do it.
干这活儿很难。没有一个人能干这活儿。

注意：在表示允许、可能、惊异时用can或could，一般不用be able to。如：
You can go now. Right now, all right?
你现在可以走了。马上走，好吗？
Can (could) 可以用来指比较委婉地提出请求，疑问或看法。而be able to 不能这样用。如：
— Can I take a message for John?
— Yes, thank you.
我给约翰捎个口信好吗?
— 好的，谢谢。
Could you wait a few days for the money? I’ll return it to you in a few days.
这个钱你们等几天行吗？过几天我就还给你。
另外，was able 还表示”成功地做到”，相当于managed to do sth/succeeded in doing sth
2. We can come up with the answer together. 我们可以一起发现答案。
come up with (an answer)意思为find or produce a way to solve, or an answer “发现， 产生/解决办法或答案”。但是，不能说An idea is come up with。如：

— How could he come up with this idea?

— 他怎么想出这个主意的？
3. We just need to keep working on it and not give up. 我们需要坚持做下去，不能放弃。
（1）keep dong sth.意思为“继续做某事”或“不断/反复做某事”。如：
Keep reading, and your English will be better and better.
坚持，你的英语会越来越好。
Keep on doing something也是继续做某事的意思。但是，此时表示在持续的过程中时有间断。如：
He is a famous writer. He keeps on writing every day.
他是一位著名的作家。他每天都坚持写作。
work on sth意思是“从事……工作”如：
The writer is working on a new book. The scientist is working on a new plan. We must work hard on all subjects.
这位作家正在写一部新书。科学家正在研究新计划。我们应该努力学习各门功课。
（2）give up 意思为“放弃，停止”，后面可跟动名词形式作宾语。如：
Give up smoking! It’s no good to you! 戒烟！烟对你没好处！
I can do nothing more. I have to give up.
我无能为力，只好放弃。
4. Which of these do you think is the second most useful invention?
你认为哪一个是第二有用的发明？
(1) do you think 是插入语，常置于疑问词之后，不能置于疑问词之前，作“你认为……”解释。如：
— How old do you think my father is?
— I think he’s fifty.
— 你认为我父亲多大年纪了？
— 我想有五十岁吧。
— Who do you think will teach us English this term?
— Mr Li, I think.
— 你认为这个学期谁将教我们英语？
— 我想是李教师。
(2) 在最高级前加系数词second, third…，表示程度比较次要，意思为“居第二/ 第三位的……”。如：
Changjiang River is the longest one in China. And Yellow River is the second longest one.
长江是中国最长的河流，黄河是第二长河。
Bill is the second tallest in our class.

爱迪生是个伟大的发明家。他发明里许多东西，一生中有1093项发明。
5. When he was a child, he was always asking questions and trying out ideas.
当他还是个孩子的时候，他总是问一些问题，试验一些新的想法。
（1）always与进行时态连用，表示说话人厌烦、赞赏、不满、批评等情感，意为“总是……”。如：
The girl behind me is always talking in class.
坐在我后面的女生上课总是讲话。 （表示厌烦）
The PLA are always doing good deeds for the people.
人民解放军总是为人民做好事。 （表示赞赏）
（2）try out 意为“试验；试用”。如：

答案：A
6. Most of the questions had nothing to do with his lessons. 多数问题都与他的功课无关。
have nothing to do with 意思是“与……无关“。如：

你在另一个城市。这跟你没有关系。
另外：
have something to do with 与……有关
have much to do with 与……有很大关系
have a little to do with 与……有一点儿关系
have little to do with 与……几乎没有关系
注意：此处的替换词都是不可数的，不能用many, a few，或few替换。疑问句中要用anything，如：
— Did her speaking have anything to do with the question?
— Yes, it did. What she said had something /much /a little(little) to do with our work.
— 她的话与问题有关吗？
— 是的，她的话和我们的工作有些关系/有很大关系/有一点儿关系(几乎没有关系)。
7. The teacher didn’t want to teach Tom any more. 老师再也不想教汤姆了。
not…any more 意思为“不再；再也不”相当于not…any longer，通常可用no longer代替，在句中作状语，表示动词或状态不再延续。如：
I can not wait any longer /any more. = I can no longer wait.
我再也不能等了。
8. He learnt very fast and became very interested in science.
他学得很快，对自然科学产生了浓厚的兴趣。
be (become ) interested in …对……感兴趣。注意此处是interested，不是 interesting。

那女孩对唱歌跳舞感兴趣。我弟弟对画画感兴趣。他们都有自己的喜好。
9. Edison saw a little boy playing on the railway tracks at a station.
爱迪生看见一个小男孩在车站的铁轨上玩。
see sb doing sth 看见某人正在做某事，表示某人的动作正在进行，用现在分词；see sb.do sth.看见某人做某时，表示某人的动作已结束，使用省略to的不定式。如：
A thief robbed Jim’s wallet last night. Mary saw a wallet lying on the ground after that. I said I saw the thief enter the shop twice that day.
昨晚，一个小偷抢了吉姆的钱包。之后，玛丽看见地上有个钱包。我说我曾看见那个小偷进了那家商店两次。
10. The boy was too frightened to move. …The boy’s father was so thankful that he taught Edison how to send message by telegraph.
男孩吓坏了，动不了。……男孩的父亲非常感激他，就教爱迪生如何通过电报发送信息。
（1） too…to…太……以致不能……
too 后只能接形容词或副词, too…to可以转换成so…that…。so+形容词/副词+that +从句 意思为：“如此；以致于”转换后的that从句应是否定句。如：
She is too young to do the job. = She is so young that she can’t do the job.
他太年青了，不能做这项工作。
The book is too difficult for me to read. = The book is so difficult that I can’t read.

我愤怒得说不出话来。
He spoke so fast that I could hardly follow him. = He spoke too fast for me to follow.
他讲得太快，我几乎听不懂他的话。
注意后一句中follow 后面不能再接him，因为:如果不定式动词与主语具有逻辑上的动宾关系，则不能再加宾语。
（2）句型such(a/an)+形容词+名词+that从句,也可表示 “如此……以致于……”。such后面的名词可以是单数，复数或不可数。如：
This is such a good book that all of us like it very much. =
This is so good a book that all of us like it very much.
这是一本很好的书，所有的人都喜欢看。
She is such a good teacher that all of us love her. =
She is so good a teacher that all of us love her,
她是一位好老师，我们都爱她。
注意：在such…that 句型中，当such后的名词有many, much, some, few, little several等词修饰时则需用so…that句式。如：
She has so few friends that she is always lonely.
她们很少有朋友，以致于总是寂寞的。
I’ve so many falls that I’m black and blue all over.
我摔了这么多跤，弄得全身青一块紫一块的。
11. What do you want to do after you graduate from school? 你毕业后想做什么？
句中graduate 作动词，后接介词from，如：
I want to be a teacher after I graduate from school.
我毕业后想成为一位老师。
12. Don’t you think his radio is too noisy? 难道你不认为他的收音机太吵了吗？
分析：这是一个否定疑问句，相当于“难道不……?”回答以事实为根据，事实是肯定的，回答用Yes。中文翻译为“不”；若事实是否定的，回答用No，中文翻译为“是的”。如：
— Don’t you think they speak too quickly?
— Yes, I do.
— 难道你不认为她们讲得太快了吗？
— 是够快的。
13. Let’s ask him to turn it down. 我们让他把收音机音量关小。
turn down意思为“把音量关小“，反义词是turn up把音量开大，类似的短语还有：turn on “打开”，turn off “关掉”，其中on, off ,down, up都为副词，因此代词作宾语，必须位于动词之后，副词之前。如：
The TV is too noisy. Please turn it down.
电视机太吵了。请把音量关小。
Please turn off the lights when you leave home, and turn up the radio. Then nobody dare break in.
当你离开家的时候，请关灯，将收音机开大一点。没人敢闯进来。
三、语法
动词不定式(一)
动词不定式是非谓语动词的一种。所谓非谓语动词就是不能做谓语的动词结构。正因为如此，所以他不受主语的人称和数的变化的影响，不必和主语保持一致，没有人称和数的变化。不定式是由to＋动词原形构成，这个to只是不定式的一个符号，没有任何实际意义。另外，由于是动词不定式，他自然具有了动词的性质，因此可以带宾语和状语，不定式加上它的宾语或状语构成不定式短语。虽然不定式不能做谓语动词，但是可以作除谓语以外的其它句子成分。
动词不定式极其短语在本单元中出现的几种语法功能：
1） 用作宾语
I’ve begun to learn English.
我已经开始学英语。
The old man always forgets what to do.
那位老人总是忘记该做什么。
Liu Mei wanted to ask the teacher a question.
刘眉想问老师一个问题。
句中to learn English, what to do, to ask the teacher a question分别作谓语动词begun, forgets, wanted的宾语。
动词不定式作及物动词的宾语，常用的及物动词有begin, want, hope, forget, remember, like, love, need, try, ask, learn, wish, agree, choose, start：等。
2） 用作宾语补足语
Tell the child not to play on the road.
告诉孩子们不要在路上玩。
My father told me to turn the radio down.
我父亲告诉我要我把收音机的音量调小些。
I often help my mother (to) do housework at home.
我经常在家帮助妈妈做家务事。
句中not to play on the road, to turn the radio down, (to) do housework at home分别作tell, told, help的宾语补足语。
注意：
1．作动词ask, like, tell, want等的宾补时，动词不定式要带to。如：
2．表示感官和使欲的动词，如：let, make, feel, hear, see, watch等，作这些动词的宾补时，动词不定式不带to。如：
My parents don’t let me swim in the river.
我父母不让我在河里游泳。
Did you watch the old man get into the bus?
你注意到那位老人上了公共汽车吗？
3． 作动词help的宾语补足语时，动词不定式可带to，也可不带to。如：
Could you help me (to) do the cooking this afternoon?
今天下午你能帮助我做饭吗？
He can’t help me (to) mend my bike.
他不能帮我修理我的自行车。
