英语问题求教现在完成时后可不可以跟动作完成的具体时间,例如I have returned the book yeater

i returned the book to the library的同意句 英语翻译I returned the book that I ----- ------- 请问i read the book和i have read the book的具体区别 --Have you returned the book to the library__?--Yes,I have__ 英语现在完成时问题Mike,where have you _____?I have _________ the libr 十万火急的英语问题：he has written a book the name of which i have for 现在完成时是已经完成的动作吗? NO后面接名词的问题例如我没有书是 I HAVE NO BOOK 还是 I HAVE NO BOOKS 一般过去时和现在完成时 和过去完成时的区别 一般现在时和现在完成时的区别 具体动作的时间空间上的区别! 八下英语现在完成时I bought this book two months ago.(同义句)I have (had) 现在完成时例句：I have finished reading the book,read要加ING? 现在完成时问题过去完成时不是说有两个表示过去的时间词时就用过去完成时么I have taught here since
