问题描述：
When you ___ at the station,give me a ring and then I'll come and fetch you in my car.
Please explain among (1),(2),(3),(4),and(5) in mandarin.
Please choose from following sentence as below.
1)have arrived
2)arrived
3)arrive
4)will arrive
5)would arrive
答
1)have arrived没有必要用完成时态,因为连词when已经表明了“在.时间之后”,故错误.
2)arrived一般过去时不能表示一般将来时,故错误.
3)arrive在时间状语从句中,可以用一般现在时来代表一般将来时,正确；
4)will arrive在时间状语从句中,不能写成一般将来时,故错误；
5)would arrive是过去将来时,也不是一般现在时表一般将来时,故错误.
