一般將來時
一般將來時主要用于：
表示將要發(fā)生的動作或情況
e.g. Tom will have a bike of his own.
與這個時態(tài)連用的時間狀語常用：
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來時態(tài)與其它結(jié)構表將來情況的區(qū)別：
一般將來時態(tài) ：主要從時間的角度表將要發(fā)生的動作或情況。
be going to 結(jié)構 ：①表(主觀上)打算或準備做某事時。 ②表有發(fā)生某事的預兆時。
e.g. They are going to have a competition with us in studies. It is going to rain.
據(jù)以上區(qū)別，故下面一句是錯的：
I am going to be eighteen years old next year.
應改為： I shall be eighteen years old next year.
be about to do sth 結(jié)構 ：意為"剛要做某事"、"馬上要做某事"強調(diào)時間之緊迫性。
e.g. We are about to discuss this problem.
