现在完成时的填空题.原句；He has just bought (buy)an Australia car课后练习有一道按原文填空的题He just _____(buy)an Australia car这时填什么呢?原因? 初三英语现在完成时的1题he has already finished his homework改成否定句 现在完成时的否定句是怎么改的he has gone to moscow改否定句：1：he hasn't gone to moscow2：he don't has gone to moscow------------------------------那句对,都对没?还是都错, has turned into和has been tuened into有什么区别原句：We're very happy that Qinghuai River has turned into a clean river.但我觉得是has been turned into 不是现在完成时的被动语态吗? 现在完成时可以和now连用吗比如：He has gotten up now.这句对么? 两道现在完成时的题1.Where is Mr.Liu?---He ( )the library.A.has been to B.has gone to C.has been in答案写的是选A 可是我觉的怎么是选B呢?2.Miss Gao left an hour ago .(改写句子,句意不变)是改成Miss Gao has been away sin He left Wuhan two weeks ago.改为现在完成时还有一个题Susan has been in this city for more than ten years.改为同义句 He has been saving money to buy a portable computer.句中的时态是否是现在完成时,用现在完成时表示持续到现在的动作或状态.请问我这样理解正确吗? have/has been done 是现在完成的被动语态但He has been there for six months .这个句中的has been 与前面所说的现在完成时的被动有关系吗? 现在完成时的回答句 填空 .I （become） a Christian when I was a child.此句填have become 还是became 从他是一个小孩开始,他就是一个基督徒（Christian） 这句话的翻译,同样不清楚是用现在完成时还是过去时 He has been a Christian 问道填空题：he never _______ (go) to school since last year.按照时态,这个句子应该是现在完成时,填has,但never能放在主动词has前吗? He has been here since 1996=（ ）（ ）9 years since he （ ）here此题所在单元教的是~现在完成时~ he has always come late 用 现在完成时 造 因为我看到书上有句he has always been a good neighbour He【 has gone to】谓语 Beijing 现在完成时和过去完成时的have 与 had都是助动词吧 现在完成时的has gone has been问题where has John gone?To the library.He has been there an hour.第二句是不是他去那里已经一个小时了?为什么要用has been 而不用has gone呢?has gone 不是表示去了哪里还没有回来吗 用动词的现在完成时填空 He has more time time than i 保持原句不变 I____have_____much time as he
