英语中考语法复习：主将从现

（重难点、易错点+中考真题+强化训练）

 

一、定义

“主将从现”是指在复合句中，如果主句表示将来的动作或状态（主句用一般将来时），那么由某些连词引导的状语从句（主要是时间状语从句和条件状语从句）则用一般现在时来表示将来的动作或状态。

结构公式：

主句 (将来时) + 连接词 + 从句 (一般现在时)

核心连接词：

       时间状语从句：when (当...时候), as soon as (一...就...), until/till (直到...), before (在...之前), after (在...之后), once (一旦)

       条件状语从句：if (如果), unless (除非 = if not), on condition that (条件是)

例句 ：

1. I will call you when I arrive at the station.

主句：I will call you (一般将来时)；

从句：when I arrive at the station (一般现在时)

译：当我到达车站时，我会给你打电话。

2. If it doesn't rain tomorrow, we will go to the park.

主句：we will go to the park (一般将来时)；

从句：If it doesn't rain tomorrow (一般现在时)

译：如果明天不下雨，我们就去公园。

 二、 重点

1.  核心时态搭配：牢记“主将来，从现在”。

       条件类: if (如果), unless (除非), as long as (只要)

       时间类: when (当...时), as soon as (一...就), until (直到...为止), before (在...之前), after (在...之后)

3.  主句的多样性：

①　主句用 will/ shall/be going to + do 表示将来 主将从现

②　祈使句：   主祈从现

三、 难点

例：I will go(主句)if it is fine tomorrow(从句，由if引导).
