一天怎么快速记住20个单词
can (v)能,常考词
讲解:常和be able to; must 进行区别考试
1.can 与be able to答题关键在于情态动词构成句子的基本结构
例: He will be able to finish it. 此句中的时态是 will v原,而can不能单独构成谓语,即:不能放于v原的位置,所以此时只能用be able to 不能用can. 考察基本语法是否扎实.
2.can 还可表示:可能.这是很多同学容易忽视的意思.
例: There is light in the room. There can be a person in it. 屋子里有灯,可能里面有人(可能有,可能没有).
3.can 表可能时,容易和must 在一起考. must 表肯定.
题: Mom hasn’t come back home. She __ be still at work now.
A. must B. can’ C. need D. can
考点分析:D can 表示可能
题: He __ be abroad now. I saw him just now.
A must B must not C can not D. needn’t
考点分析:C must的两层意思
- I must finish it.(大家非常熟悉的必须的意思)
- The road is wet. It must rain last night.路上全湿了,昨晚肯定下雨了
注意: must表肯定时, 没有否定形式. 即:没有mustn’t
4.can 还可表示意愿,此时和would you like 的意思相同
例: Can you lend your book to me?= Would you like to lend your book to me?你愿意借你的书给我吗?
单词不只是要会默写，知道意思，更要会用,
