动词在句首为什么要改成不定式to see if there is any chance.这句话谓语see ,宾语if there is any chance我不明白有什么必要必须把see改成to see如果是see if there is any chance,see就是谓语了吧.还有to see if there 问个关于非谓语动词的问题She pretended not to see me when I passes by.请问这句为什么要用”to see”不定式?用现在分词”seeing”不行吗? I will go to see you.这个句子中的to是介词,还是动词不定式?为什么? I saw Miss Zhao.She was drawing a picture.改为同意句Miss Zhao ___ ____ ______ a picture.see用在被动语态当中,不是后接动词不定式吗?是不是应该改成Miss Zhao was seen to draw a picture.see 在被动语态当中,后面有接 i'm going to paint it pink.请问为什么这里要用动词不定式这里的动词不定式做什么语?to在这里是介词还是动词不定式符号?为什么to后不加动名词? why not go to see the pandas with us?why not 后面要跟动词原形,现在跟了动词不定式 是为什么啊? the restaurant is here to here在句中为什么是副词,不定式有名词性,为什么副词修饰了名词性的不定式,不是副词修饰动词吗? 那个 feel,hear,notice,see,watch ...这些动词后的不定式做宾补to要省略么? 为什么“to+动词原形”叫“不定式”? 请问这里为什么要用动词不定式?he was afraid to leave his home.改成 he was afraid left his home. 这两个动词不定式在句子中做什么成分This was even more exciting to see than the rapids where the water seemed to boil.请问动词不定式to see和to boil在句中做什么成分? 主动句中,感官使役动词作宾补为什么要用省to的不定式 动词不定式分别在这些句子中充当什么成分?为什么?To get on well with the classmates is important for me.Who wants to have another try?Dad went to the hospital to see his friend. 动词不定式的是什么成分nice to meet you 中动词不定式 to meet you 在句中担当什么成分,请写明原因. there will be a friend________here to see me tomorrow.A:to come B:coming 我认为选A对吗如果不对,那为什么句中动词see 用了不定式形式呢?那么come也应该用不定式表示将要发生的动作啊 为什么含有感官动词和使役动词的不定式要省略to 动词不定式的否定式是在to 前加not,而want to 为什么不能 不定式的作用,在下面这句话的作用.they thought of the idea to cycle along the Mekong River. 其中的TO CYCLE ALONG 的动词不定式有什么作用啊,为什么要用不定式
