英语作文中“能”的高级表达
can,be able to
举例如下：
我能帮助你吗？
Can I help you
你能联系上你父母吗
Are you able to reach your parents
能，会用英语怎样表达_
A well-known proverb goes that “where there is a will, there is a way”, which means that one can find a way to success as long as he or she has a strong will With a strong will, one can focus all his energy on one point, which makes his success possible Without a strong will, however, one can be easily distracted from his goal or discouraged by setbacks, which leads to his ultimate failure
History abounds with examples of strong-willed figures winning success Actually, there is no better illustration of the proverb than the deeds of Gou Jian, king of Yue in ancient China Defeated by Fu Chai, king of Wu, Gou tried every means possible to steel his will Eventually, with the help of Fan Li and Xi Shi, he managed to rebuild his country and his armies and had Fu Chai taste the bitterness of failure
In short, a strong will is essential if we want to make achievements in our studies or work, or indeed in any other aspect of our lives One should lose no chance to strength his will and remember, God helps those who help themselves
1sb can do sth/sb could do sth/sb may do sth
2sb be able to do sth /sb be capable of doing sth
不同的表达方式区别并没有很大，试着比较下：
can, be able to
这两者都有“能”的意思。其区别在于:
1can还可表示“可以”“可能”,即具有某种感情色彩。例如:
Can I come in我可以进来吗
That can't be true那不可能是真的。
以上两句都不可换用be able to。
2can只有现在时和过去时两种形式,而be able to则有多种时态形式。试比较下面两句:
Will you be able to come tomorrow
你明天能来吗(将来时)
This factory has been able to produce newly-devised sewing machines
这家工厂已能生产新设计的缝纫机了。(完成时)
3在be able to之前可加用另外一个助动词,且多用于否定或疑问结构,而can则无此用法。
4用于否定结构, be able to表达一时情况,而can则表达往常情况。试比较下面两句:
He is not able to swim today
他今天不能游泳。
He can't swim at all
他根本不会游泳。
5be able to后可接系表结构,表示一种状态或性质;而can没有这种用法。例如:
He was able to be cold about her now他现在对她可能有些冷淡。
6be able to有非谓语动词形式,而can则没有。例如:
I hope to be able to do the work我希望能做这项工作。
