Unit 6 I’m going to study computer science.


1. Were you able to keep them?
be able to表示＂能够＂，相当于 can，常用来表示 can不能表达的将来时或完成时的情况，可用于各种时态。
He will be able to finish reading the book next week. 他下周将能读完这本书。
【易混辨析】
can / be able to
(1) can＂能＂，表示过去或现在＂能力所及＂时，与be able to 通用。
He can / is able to speak German. 他会说德语。
I could / was able to run very fast when I was a boy. 我小时候就跑得很快。
(2) be able to的过去式还可表示一种＂经过努力做到了＂的意思。而can的过去式则没有这种意义。
He started late, but he was able to catch the train. 他出发晚了，但他还是赶上了火车。
(3) can通常只用于过去或现在两种时态，而be able to 则可用于各种时态。
He has not been able to come since he got hurt. 自从受伤以后，他就一直未能前来。
(4)在表示猜测时，只能用can，而不能用be able to。
That can’t be your bag. 那不可能是你的书包。学/科*+网

Finish your homework first, then you’ll ___________watch TV for an hour.
A. can B. be able to C. may D. could
【答案】B
【解析】can＂能够＂，不能与将来时连用；need＂需要＂；be able to＂能够＂，可用于各种时态；may＂可以， 可能＂。根据句中的will可知句子时态是一般将来时，四个选项中只有be able to可以和will连用，故选B。
2. promise n. 承诺；诺言　
v. 许诺； 承诺；保证
make a promise/promises 允诺[来源:学科网]
keep a /one’s promise 遵守诺言，信守承诺
break a /one’s promise违背诺言

improve此处用作及物动词，意为＂改进；改善＂，还可用作不及物动词。

The weather is beginning to improve. 天气开始好转了。
【注意】
improve相当于make ... better，已包含better之义，再加上个better，即属赘余。

正：We hope to improve our work.
【知识拓展】
improve名词形式为improvement
self-improvement 自我改进；自我提高
4. Many resolutions have to do with self-improvement.
have to do with关于；与……有关系。这个句型表示与某事、某人有牵连，有关系，有瓜葛。

6. Sometimes the resolutions may be too difficult to keep.
too…to…是＂太……以致不能……＂，to是不定式符号，后接动词原形，该句式虽没有否定词not/no，但表达否定意义，若逻辑主语是动作的执行者，则需用 for 引出。
English is too difficult for me to read. 对我来说英语太难了。
【知识拓展】　
(1) too…to…可转化为复合句 so…that…句型，此时that从句的谓语动词要用否定形式。
The problem is too difficult for me to work out.
=The problem is so difficult that I can’t work it out.
(2) too…to…还可转化为＂not+形容词/副词+enough to do＂，其中形容词/副词是句型too…to…中形容词/副词的反义词。

There is no book on the desk. 桌子上没有书。 (no=not a)
There is no water there. 那里没有水。 (no=not any)
