have been to 的用法以及怎么判断从句
总是不知道have been to的用法,还有过去完成时该怎么用?have+p.have been + p.该怎么用?过去时与完成时的区别是什么?怎么判断一个句子是宾语从句,还是定语从句?宾语从句的关系代词一般用that吗?.

助动词have的用法 1）have+been +过去分词,构成完成式被动语态,例如：English has been taught in China for many years.(中国教英语已经多年.) 2)现在完成进行时构成：have / has been + 现在分词用法:)下面详细举例：用于表示动作从过去某一时间开始一直延续到现在或离现在不远的时间,动作是否继续下去,则需视起来而定.如：How long has it been raining?雨下多久了?She has been sitting there for more than 2 hours.他已经在那坐了两个多小时了.We’ve been seeing quite a lot of each other recently.最近我们常常见面.He has been telephoning me several times in two days.这两天他打了好几次电话给我.注意：使用现在完成进行时还有以下一些情况：一般现在时主要由动词原形表示,但第三人称单数后要加词尾s,另外be和have有特殊的人称形式例：it all depends he coves sports i know it 现在进行时由助动词be的人称形式加现在分词构成例：i am working 一般将来时由助动词shall will加动词原形构成例：i shall go you will go 一般过去时由动词的过去式表示例：i was glad to get your letter 现在完成时由have的人称形式加过去分词构成例：i have read it he has read it 过去进行时由be的过去式和现在分词构成,主要表示过去某个时刻正在进行的动作例：the wind was no longer blowing．过去完成时由had加过去分词构成,主要表示过去某时前业已发生的动作或情况例：they showed us the new machine tools they had turned out 一般过去将来时由should would加动词原形构成,表示从过去某时看来将要发生的事情例：he was sixty－eight,in two years he would be seventy 现在完成进行时有have（has）been 加现在分词构成例：how long has it been raining?过去完成进行时由had been加现在分词够成例：it had been raining for two days the fields were all under water．
