逻辑主语问题I’m going to the post office,for I have a letter to post .( 逻辑主语是I ) Thank you.But I have no letters to be posted now 能否解释一下为什么这两句话逻辑主语不一样 是根据什么判定的? 有关不定式主动表被动的问题参考书上说,如果句子的主语不是不定式的逻辑主语,那么不定式就需要用被动语态来表示.有一个例句：A:Li Ming,I‘m going to the post office .I know you have a important letter 英语语法问题.I don't feel good;I'm afraid ,I'm going to英语语法问题.I don't feel good;I'm afraid ,I'm going to be sick.为什么I'm going to 后面要加be .sick在此是做名词还是形容词I will be fifteen years old next year.这里 I'm going to I'm going to I'm going to 英文I agree to help him,不定式的逻辑主语是什么?什么叫逻辑主语 I'm going to telephone him怎么改成用he作主语 I'm going to be a singer.主语 谓语 宾语 还有其它什么语,分别是什么? 逻辑主语问题i ma going to shanghai to attend an important meeting tomorrowdo you have anything to be taken to your brother为什么用to be taken而不是to take呢就像i have a lot of homework to do一样 关于句子的逻辑主语 有个句子There are five pairs ______,but I’m at a loss which to buychoose from 我们老师讲I为句子逻辑主语 那么句子的逻辑主语怎么判断 choose from是不是他的形式看逻辑主语呢 英语语法问题I'm going to go cry和I' m going to cry哪句英语对,为什么呢? I'm going to marry I am going to ().I'm going to ().().I'm going to ().().I'm going to ().().I'm going to ().I'm going to ().That wiu be fun!I can't wait.括号里的填做什么或者填时间. i am going to telephone him.把主语变成he i'm going to wear a T-shirt,T-shirt划线提问 I'm not going to Beijing .He isn't going to Beijing,either.(合并为一句话） __ he __ I _ going to sorry,I haven;t finished your book _____ ,but I;m going to.Ayet B already
