什么情况下用一般现在时表示一般将来时
在时间、条件等状语从句中,用一般现在时表示一般将来时。
在一些情况下,一般现在时能用来表示将来时。
1、谓语动词是:come,go,arrive,leave,start,begin,return,live,fly 等,可以表示将来发生的动作。
The train leaves at six tomorrow morning.
When does the bus start? It starts in ten minutes.
2、在时间或条件从句中,一般要用一般现在时表示将来,而不用一般将来时。
When Bill comes,ask him to wait for me.
I'll write to you as soon as I arrive there.
3、谓语动词是 hope,take care that,make sure that 等后的宾语从句中,用一般现在时表示将来。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.
4、这种时态可以和一个时间短语连用以表示已确定的、对将来的安排:
如:The boys start school on Monday.男孩们星期一开学。
I leave tonight.我今天晚上动身。
5、这一用法代替了较常用的现在进行时态:
如:The boys are starting school on Monday.男孩儿们星期一就要开学了。
I’m leaving tonight.我今天晚上就动身。
6、这两种时态之间的差别是:
⑴一般现在时比现在进行时具有的个人色彩更少:I’m leaving tonight通常可能含有我决定离开的意思,但I leave tonight可指这是计划的一部分,但计划不一定是我订的。
⑵一般现在时要比现在进行时听起来更为正式。计划开办一个新分店的百货商店很可能说Our new branch opens next week(本店新设分店下周开业),而不说Our new branch is opening next week。
⑶现在进行时显得累赘的地方就用一般现在时,例如在谈到像旅程安排那样的一系列预定的将来的动作时,可以这样说:
We leave at six,arrive in Dublin at ten and take the plane on?
我们6点出发,10点到达都柏林,并在??乘飞机??
而不说:
We are leaving at six,arriving in Dublin at ten and taking the plane on然而要注意,在像My train leaves at six(我常乘坐的火车6点开)这样的句子中,用一般现在时表示习惯性动作,这里就不能用现在进行时来代替。
在正式的英语语法里,用现在进行时表示一般将来时用来表示按计划近期内即将发生的动作.例如:
We are meeting him after the performance.
I'm going to Qingdao for the summer holiday.
When is Mr Manning taking his holiday?
用现在进行时表示一般将来时的用法海常见于某些时间状语分句核条件状语分句中.例如:
I'll think about it while you're writing the report.
When you are talking with him,take care not to mention this.
注意,用现在进行时表示一般将来时,在句中或上下文通常有表示将来时间的状语或其他依据,否则意义便含糊不清.
比较:
Are you doing anything special tonight?(表示将来)
Are you doing anything special now?(表示说话时正在进行的动作)
Are you doing anything special ?(可作以上两种解释,以上下文而定)
