attack are attacked
②unless you take your own food with you.

bring 指从别处拿到这里来,或指拿到说话人所在的地方。
carry 表示“携带；运载”等,具有负重的含义,不表示固定方向。
fetch “ 去拿来”，是去某处将某物拿回来或将某人接回来。

take B. wear
C. use D. make

【点拨】考查动词辨析。句意：—汤姆，你带着把雨伞吧。看看这阴暗的天空。要下雨了。—谢谢你，爸爸。take 拿，买，花费；wear 穿，戴；use 使用；make 制作，使。take sth. with sb.“某人随身携带某物”，为固定搭配，故选A。
语法讲解
条件状语从句表示主句动作发生的条件, 在初中阶段常由if(如果) 引导, 表示“假如有从句的动作发生，就会有主句的动作发生”。
Please call me if he is at home.
假如他在家的话, 请给我打电话。
if 引导的条件状语从句
［重点］时态
如果主句是一般将来时, 从句一般用一般现在时。
I won’t go there with you if it rains tomorrow.
如果明天下雨的话, 我就不和你一起去那儿了。
考点1
中考在线1：If you take this train, you ______ in Shanghai in five hours.
A. arrive B. will arrive
C. arrived D. have arrived
【点拨】本题用语法判定法。考查动词时态。句意：如果你坐这班火车，你将在五小时内到达上海。分析句子结构可知，本题是含有if 引导条件状语从句的复合句，时态上遵循“主将从现”的原则。故选B。
B
主从句的位置
从句可以位于主句之前, 也可以位于主句之后。不过从句在前时, 主从句之间须用逗号隔开。

如果他回来了, 请告诉我一声。
语法讲解
考点2
［易错点］if 的两面性
if 引导条件状语从句时意为“如果”, 如果引导宾语从句则意为“是否”。请比较:
（1）We will go out if it is fine tomorrow.
（2）I don’t know if the train has arrived.
考点3
中考在线2：
— Would you like to go hiking if it ________ fine this Saturday
— I’d love to. But nobody knows if it _______.
A. is; will rain B. is; rains
C. will be; will rain D. will be; rains
A
【点拨】本题用语法判定法。考查动词时态。第一个if 意为“如果”，引导条件状语从句，从句中应用一般现在时表示将要发生的动作；第二个if 意为“是否”，引导宾语从句，主句中的谓语动词用一般现在时，宾语从句中可根据需要用任何时态，此处指这个星期六的天气，用一般将来时，故选A。
拓展：条件状语从句和主句还有一个共同的伙伴，有时它可以替代从句和主句，它就是“祈使句+and/or+ 简单句 ”。其中and 表示句意顺承；or 则表示转折，意为“否则”。
拓展

中考在线3：Keep working hard, and you will achieve success. (保持句意不变)
___________ __________ keep working hard, you will achieve success. [上海]
【点拨】原句意为“继续努力，你就会成功的”，由句意可知，成功的条件是“继续努力”，将其转化为if 引导的条件状语从句，人称保持一致。if 放在前，后加 you。故填If you。
If you
unless 引导条件状语从句, 相当于if 引导的条件状语从句的否定形式,即unless=if...not。中文意为“如果不……；除非”。

含unless 或if 引导的条件状语从句的复合句中，主句用一般将来时，从句用一般现在时代替一般将来时。
即所谓的“主将从现”。

A. if B. after C. unless D. when
