英语中heard和hear的区别为什么有的地方时hear 有的地方时heard 不要跟我说过去加d的= =我也知道= =难道说.真的只有这个区别? 英语中I am sorry to hear that和I am sorry to heard that有什么区别? 英语中listen和hear的区别It is too noisy.I cannot _____ the tape clearly.A)listen B)listen to C)hear D)be heard顺便说一下listen(to)和hear有什么区别?什么时候用listen(to),什么时候用hear? make ones hear和make ones heard的区别 heard +doing和do的区别使用错了，hear 英语,hear of 和hear.这是一个改错题,I heard him but i never know him.这句话中哪儿错了?答案上说是heard 改为heard of .可是这里为什么不能用heard呢?分类错了诶。貌似是英语学习。 heard,heard from,heard of和heard about的区别?听说和收到来信..有区别么? heard of和heard from的区别 heard 和heard of的区别?have you heard that?have you heard of that?有啥分别? Have you heard from Marry?为什么翻译成：你有收到marry的来信吗?hear:明明是听到,听说的意思.怎么和信扯上关系了? hear of 和hear about的区别? hear of和hear about 的区别? hear about和hear from的区别. do you hear about 与have you heard abouta的区别.have any one of you hear about sth中have的词性是? hear about ,hear of ,hear fromhear from ,hear of ,hear about 这三个短语的意思,用法有什么不同?..另:I haven't ____him for a long time.A.heard from B.heard of C.heard about 应该选哪个?为什么? I heard a dog barking outside,I heard a dog bark outside.1,那句是对的?2,如都对,要表达意思有什么区别?3.如果只有一个句子是对的，请说明另外一个为什么是错的。4.第一句为什么要用heard,而不是hear? hear,hear from,hear about,hear of,listen,listen to的区别和用法,求每一个详细的解说,区别和用法都要说,最好有e.g., listen和hear的区别
