3个英语问题 1,Did you hear the dog( bark) loudly just now 为什么是bark 而不是barking? 2,We are very happy( to clean )the floor 为什么不可以用进行时态 3,Every students has a responsibility (to look) after our earth.WHY?
1 你刚才听到狗叫了吗?hear the dog bark 是省略to的不定式做宾语补足语,强调听到的结果.如果用barking 现在分词作宾语补足语,表达“狗叫”这个动作正在进行. 2.固定搭配:be happy to do sth. 3.固定搭配:have a responsibility to do sth.类似的还有 ability,way,chance,plan ...等这样的抽象名词后常跟不定式做后置定语.
1. 刚才(just now)听到狗叫得很响,不是现在听到狗正叫得很响,所以是bark ,而不是barking. 2 be happy to do 是固定用法,没有进行时态的用法。 3.固定搭配:have a responsibility to do sth.,有责任做某事; look after 是照顾的意思,句子中引申为保护的意思。...
