_______in conversation,they didn't notice me entering the room.______in conversation,they didn't notice me entering the room.1.engaged2.engaging3.engaged themselves4.having engaged themselves为何不选原因详解
选 1.engaged
Engaged in conversation,they didn't notice me entering the room.他们忙着说话,都没注意我进屋了.
engaged 形容词,从事...的;忙於...的[(+in/on)],后面不用加反身代词,所以2,3,4都不对.
例如:
He is engaged in his business.
他忙於他的生意.
We are engaged in compiling a dictionary.
我们正忙於编一本字典.
She was engaged in protecting wild birds.
她致力於保护野生鸟类的工作.
She is now engaged in writing letters.
她现在正忙著写信.
选1
前面一句补充完整是“They are engaged in conbersation,”
而这里因为主语是一致的，所以可省略are （这里是形容词engaged 是“在使用中的，忙碌”的意思）
2不对 它是engage动词ing形式 而engage作及物动词时 是“使...忙碌” 所以用法是engage sb. with sth.
3中 应该改成engagi...

2不对 它是engage动词ing形式 而engage作及物动词时 是“使...忙碌” 所以用法是engage sb. with sth.
3中 应该改成engaging themslves 原因同2
4不符合语态和意思
收起
这里是过去分词做状语,关键是要分词的逻辑主语和句子主语保持一致.而且忙于某事是be engaged in
句子补充完整是because they were engaged in conversation......
此时engage的逻辑主语和句子主语一致,所以从句的主语谓语可以省略.
因此选A engaged做状语
1吧~
