had的后面跟过去式吗如：I had to （went or 什么）bookshop by taxi

had的后面跟过去式吗如：I had to （went or 什么）bookshop by taxi 由if引导的假设语气的问题,如：If i had a lot of money,i would buy a car.没if连接的那个子句必须要用到过去式助动词吗?后面直接i bought不行吗? had的过去式 i had judged another person simply for what i assumed she had to be...had to是肯定的意思吗.因为to后面必须跟动词原形,所以用另外一个be吗 英语过去式中加了be后面的动词还要改过去式吗例：I had a lot of work to do last Saturday ,so I _____( not go ) out at all.和Sorry ,I don't know.I _____(not notice)him leaving.怎么写?快快快速度啊！！帮帮忙！！！ had后面可不可以接动词过去式 过去式had had been 是 was 的过去式吗I liked to run after I had liked to walk 这个是过去式的先后次序吗句式正确吗 过去完成时态=主语+had+过去分词 可是had不是助动词吗?助动词后面不是跟动词原形吗?这不是很矛盾?比如：He told me he had finished 这个had后面跟了finish的过去分词 had 后面能不能加nothave 和has 过去式后能不能加 not,变成hadn‘t? HAD是不是HAS的过去式? 过去式的用法be动词的过去式或had后面的动词用原形还是动词过去式?举例! 句子里的两个had是什么意思I had a strong suspicion that Tom had seen me coming.这句英语中的两个had是什么意思,句中的strong又是什么意思,是跟had一起的词组吗 had后面跟原型还是过去式选择题;they had great fun _____on the beach.A.to play B.playing C.play D.played I knew that my turn had come.这句话怎样理解后面的had 为什么用had?而且had后面come为什么用原型?不懂诶. had（过去式）后面的chat要用过去式吗?为什么.They sat down under a big tree and 【 】a 【 】 (chat ).根据所给单词填空 I wish I had some one like that 中'had'的形式是过去式还是过去分词为什么?谢谢 had在否定时,后面的动词是什么时态?He hadn`t won the Pritzer Prize until 1955.中的won是过去式,否定形式的也要是动词的过去分词吗？
