if条件句
if条件句:条件句用于陈述语气,表示假设的情况可能发生,其中 if 是“如果”的意思,引导条件状语从句,if从句用一般现在时,主句则用一般将来时。
(主将从现)
构成 | if从句 | 主句(主将从现) |
时态 | 一般现在时:主+be(is/am/are)+其它(名/形)。主+V原+其它。主(单三)+V(单三)+其它。 | 1.一般将来时: 主语+shall/will+V原2.主句是祈使句3.主句含有情态动词Can, may , must等词4.主句含有want, hope , wish 等表愿望的词 |
例句 | If I am an teacher,If you come back,If he comes,If you can come,If I have much money | I will be busy.call me please.he will take us to the zoo.please let me know.I may take a trip. |
注意:在与if条件句连用的主句中我们一般用will 表示将来时,而不用be going to 表示将来时。
PS:在when(当…时候), after, before 等引导的时间状语从句中,如果主句为一般将来时,从句要用一般现在时表示将来(主将从现)。如: I will call you when I reach Canada. 我一到加拿大就给你打电话。
