he has bought an australian car and has gone to alice springs时态问题以及其他几句
我不知道一般说话时候,什么情况用过去完成时,什么情况用过去式,新概念第二册中有一些问题请教大家:
1.he has bought an australian car and has gone to alice springs.buy不是瞬间动词吗,这里为什么要用过去完成时呢?为什么不用he bought an australian car?
2.I have just received a letter from my brother,Tim.He is in australian.He has been there for 6months.
同样搞不清楚什么情况用完成时或过去式,为什么不用i just received a letter from my brother?
接下来一句更不懂了,既然he IS IN australian.为什么要用he has been there for 6 months?他既然现在在澳大利亚,为什么后面一句又用完成时,他去了澳大利亚6个月?
3.last summer,i went to italy.我知道这里有last summer所以要用过去式.但是一般这种去了回来了不是应该用i've been to italy吗?如果用过去式就是强调去的动作吗?如果这里没有last summer,用过去式会不会奇怪呢?
he has been there for 6 months为什么不用he has gone there for 6 months呢,have been不是去了回来了吗?我们老师说gone表示去了没回来.

1、概念解析
1)一般过去时,表示过去某个时间发生的动作或存在的状态
2)一般现代时,表示目前存在的状态、特征、客观真理
3)现在完成时,表示过去发生或已经完成的动作对现在造成的影响和结果,或从过去已经开始,持续到现在的动作或状态.
4)现在完成时与一般过去时区别:
现在完成时表示过去发生的某一动作对现在造成的影响或结果,强调的是现在的情况,而一般过去时只单纯表示过去的动作或状态,和现在不发生关系,强调的只是过去的动作.
现在完成时常与模糊的时间状语连用,或无时间状语.一般过去时,常与具体的时间状语连用.
2、例句分析
1)buy作为购买讲时,是瞬间动词,只是强调后面不能接一段时间,但没说不可以用于现在完成时.买车这个动作发生在过去,句意说的是“他买了辆澳大利亚车并开着车去了爱丽丝泉.”这里表示的是过去发生的动作对现在造成的影响,不是说不可以用过去式,只不过这里用现在完成时表达的意思更准确.具体参阅概念分析4)你如果只用he bought an australian car,说的就是,“他过去买了俩澳大利亚车”,现在这辆车还有没有,就无从而知了.
2)例句2,说I have just received a letter...,“我刚收到了一封信”,收到这封信这个动作是过去发生的,而句子要说的是这封信对现在产生的影响.通过【过去】收的这封信,我【现在】知道了,“他现在住在澳洲,并且已经在那里待了6个月了.”后面用he has been there for 6 months,表达的意思是“他从去澳洲这个过去动作发生开始,到现在算起来已经有6个月了”.强调的是从过去已经开始,持续到现在的动作或状态
3)对的,有表达具体时间的状语last summer,要用过去式的.用现在完成时,不能跟表达过去的时间状语连用.这里用I've been to Italy.是完全正确的,不是说不行.只不过,这里原句强调的意思只是过去went这个动作.分析对比一下这几个句子,你就明白了.
如:
last summer, i went to Italy.“去年夏天,我去的意大利(现在回来与否,不知道,可能还在Italy)
I've been to Italy.“我去过意大利”(现在已经回来了,肯定不在Italy了)
I went to italy.(我去了意大利,什么时候去的,不知道,现在回来了没有,也不知道)
也就是说,went这个动作发生在过去,对现在不产生影响.
而have been to,表达的意思就是去了再回来,对现在产生的影响.
只用过去式,不跟时间状语,表达的意思是多么的空白,这个你肯定看出来了.
问题补充的很好,你又忘了gone这个词的原型是go瞬间动词,后不能跟一段时间6 months连用了啊?

He has just bought an Australian car.可以说Chinese car吗 He has bought 和 He bought 有什么区别呢? He has bought it 这个句子对吗 He has just bought an Australian car and has gone to Alice Springs.为什么这里用an不用a?He has just bought an Australian car and has gone to Alice Springs.请问an不都是用在元音之前吗,这里的Australian car 都不是原因啊,为什 he has just bought an Australian car and has gone to Alice Springs.句中and后仍然需要用has gone吗主语反正都是他,and 的后项不能不用has吗?he has just bought an Australian car and gone to Alice Springs 一般疑问句是否必须用yes或no开头Has Captain Ben Fawcett bought a small aeroplane ,or has he bought an ordinary taxi?回答是他买了一架小飞机.那是不是得用yes开头呢? He has just bought an Australian car and has gone to Alice Springs,为什么用两个has,为什么不把第一个has 改成had,因为买车这个动作在go 明明是过去的过去 He has already bought the book(否定句)急 how lond has he ()[lent,borrowed,had,bought] the dictionary He has just bought another garage .有语法错误吗 What has he bought?回答加意思急.3Q he has an uncle (对an提问) he has bought an australian car and has gone to alice springs时态问题以及其他几句我不知道一般说话时候,什么情况用过去完成时,什么情况用过去式,新概念第二册中有一些问题请教大家:1.he has bought an au 变句型 英语例句:He bought an expensive CD yesterday.What an expensive CD he bought yesterday!1:She has a very kind teacher.2:Hangzhou is a beautiful city.3:It is a beautiful park.4:I‘ve got a difficult problem.5:He has drawn very 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?
