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.

 这本书太难了,我看不懂。

 I was so angry that I couldn’t speak. = I was too angry to speak.

 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。

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。

 I haven’t been able to find the book. How about tomorrow?

 那本书我还没能找到。明天怎么样?

 He must be able to use the foreign language, forgetting all about his own.

 他一定要能做到在使用外语的时候完全忘掉本族语。

 When will you be able to help me with my Chinese?

 你什么时间能够帮助我学中文呢?

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
