英语语法(动词不定式)
什么时候不定式用主动或被动语态
例如:The problem isn't easy to work out.
The building to be built here next month will be a supermarket.
Having a trip abroad is certainly good for the old couple,but it remains to be seen whether they will enjoy it.
请问具体怎么区别?
Thanks in advance
顺便问一题 -I don't know ____ with this problem.It 's too hard.
-You can ask Mr.Wang for help.
不应该用 what to do 为什么老师说用how to do?还是都可以?求分析

【动词不定式】
1.定义:动词 + 不定式to do
2.用途:
动词不定式在句中可以作句子任何成分.动词不定式的被动形式除了一般形式外还有其完成式和进行式.
[动词不定式的语态]
动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性
动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出.这一使动者我们称之为 逻辑主语,其形式如下:
主动形式 被动形式
一般式 (not) to make (not) to be made
完成式 (not) to have made (not) to have been made
进行式 (not) to be making
完成进行式 (not) to have been making
(1)语态
如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者,不定式一般要用被动语态形式.如:
It's a great honour to be invited to Mary's birthday party.(不定式作主语)
It was impossible for lost time to be made up.(不定式作主语)
I wish to be sent to work in the country.(不定式作宾语)
Can you tell me which is the car to be repaired?(不定式作定语)
He went to the hospital to be examined.(不定式作状语)
在There be结构中,修饰主语的不定式可用被动,也可用主动.如:There are still many things to t ake care of (to be taken care of).但有时两种形式表达的意思不同,如:These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)
这样看来,你的句子
The problem isn't easy to work out.不定式作宾语
The building to be built here next month will be a supermarket.不定式作定语
Having a trip abroad is certainly good for the old couple,but it remains to be seen whether they will enjoy it.不定式作宾语
OK?希望能帮到你啊!
再问: 我不太明白 为什么 第一句中 the problem不是work out这个动作的承受者? 解决问题啊...
再答: work out 是enough发出的,因为是enough to do
再问: 你是说easy?哪来的enough easy的话是形容词怎么能作为使动者呢
再答: 是easy,我刚回答了个enough的题,给混了,sorry啊! 是easy (for sb) to do sth,work out 是easy发出的,work out不是谓语
