编者按：2007年第9期本刊发表了一篇题为《〈第二课堂〉一篇文章碰中7道高考题》的文章，当时在广大读者中引起了强烈反响，并且在其后的若干年中，本刊每年都有一些句子或试题与当年的高考题高度吻合。今年高考结束后，又有某些热心的读者给本刊打来电话，说是本刊又有不少题与高考题高度相似，有的甚至是完全雷同。但是，高考作为国考，其命题是高度保密的，况且本刊碰中高考题的文章的发表时间均远远早于高考题出现的时间，有的甚至要比高考题早上好几年。所以，我们只能说：“对不起，高考题，我与你太相像了，但这并不是我的错。”

【相似程度】
同学们仔细看一看，比一比，这两道题的相似程度有多高？至少可以说是95%吧！
相同点一：两道题均为主从复合句，从句均由before引导，主句均为祈使句，且均以动词consider开头。
相同点二：两道题的四个选项完全相同，而且就连顺序都完全一样。
相同点三：两个句子的意思高度相同，完全可视为同义句，只是个别之处用同义表达代替了而已。如果将答案填入空格，两个句子及其意思如下：

Before you decide to leave your job, consider the effect it will have on your family. 在你决定辞职之前，要考虑一下你的决定对你的家人有何影响。
【考点分析】
事实上，重庆卷的这道高考题是一道典型的陷阱题，许多同学一看试题所给的选项就以为此题是考查非谓语动词的用法，而一些自作聪明的考生首先就排除了选项A，因为consider是动词原形，不属非谓语动词的范畴，故将其排除。
做对此题的关键是要注意此句是一个主从复合句，主句为祈使句，从句为before引导的时间状语从句。既然主句为祈使句，所以就应用动词原形，而不能用非谓语动词。也就是说，命题者对于此题的设计思路是：以祈使句为考点，用非谓语动词来干扰。类似的考题主要有以下几种结构类型：
一、主句为祈使句，从句为状语从句
其中状语从句主要为时间状语从句，可能由before, when, until等来引导。如：
1. 从句由before引导
Put it in your diary before you forget. 用记事本记下免得忘了。
Remember to bolt the door before you go to bed. 记住上床前把门闩上。
Don’t go jumping to conclusions before you know the facts. 了解事实之前，不要匆匆下结论。
有时before后接的不是句子，而是动词的-ing形式。如：
Save the document to disk before closing it. 关闭文件前把它保存到磁盘上。
Before signing the contract, read the small print. 在签署合约以前，请详读小号字印出的内容。
2. 从句由until引导
Stir the mixture until it looks creamy. 将混合料搅拌至乳脂状。
Continue until you reach the end of the road. 继续走，一直走到路的尽头。
Please remain seated until your name is called. 点到名字之前请不要站起来。
3. 从句由when引导
Press the buzzer when you want to talk. 你想讲话的时候就按蜂鸣器。
Do not open the door when the train is in motion. 列车行驶时不要打开车门。
Wipe your feet when you come in from the street. 从街上回来进门时要在擦鞋垫上蹭蹭脚。
有时when后接的不是句子，而是动词的-ing形式。如：
Avoid bending at the waist when lifting heavy objects. 举重物时不要弯腰。
Be extra careful when walking along country roads. 在乡间小路上散步要格外小心。
二、用and或or 连接的并列句，其中至少有一句为祈使句
Keep to the path or you may get lost. 沿着小路走，否则可能会迷路。
Do what he wants, or you will upset him. 按他的要求做，否则你会惹他不高兴。
Call me next week and we’ll try and make a date. 下周打电话给我，我们争取定个时间见个面。
Follow these few simple rules, and you won’t go far wrong. 遵守这些简单的规则，你就不会出什么大错。
三、用破折号连接的句子，其中至少有一句为祈使句
Don’t just stand there―do something. 别光站在那儿，做点什么。
Sit down―you’re making me nervous! 坐下吧――你站着让我很紧张！
Take a safety tip from me―get that light mended! 听我一句安全建议吧――找人修修那盏灯！
Slow down―there are speed traps along this stretch of road. 开车慢一点，这段路有好几处车速监视区。
