题目内容
11．在你们离开教室之前，要确保所有的电灯都关了．（make sure）Make sure that all the lights are turned off before you leave the classroom．．分析 Make sure that all the lights are turned off before you leave the classroom．
解答 答案：Make sure that all the lights are turned off before you leave the classroom．．
首先分析句子的时态和结构：表达"确保"用make sure 后面跟that 从句，从句表述的是一般性的事实用一般现在时，"所有的灯都关了"其中主语all the lights是动作turn off的承受者，所以用被动语态，一般现在时被动语态的构成是：主语+am/is/are+动词的过去分词，时间状语从句"在你们离开教室之前"用before引导，短语"离开教室"是：leave the classroom，故答案是：Make sure that all the lights are turned off before you leave the classroom．
点评 此题考查对整句话的翻译，做这类题时先分析所给汉语句子意思确定相关的词汇和句型，然后仔细推敲时态考虑人称和数的变化等容易出错的问题．

2．In common with many countries，Britain has serious environmental problems．In 1952，more than 4，000people died in London because of the smog．The government introduced new laws to stop smog from coal fires and factories and the situation improved a lot．
Today，London is much cleaner but there is a new problem：smog from cars．In December
1991，there was very little wind in London and pollution increased a lot．As a result，about 160
people died from pollution in just four days．
Part of the problem is the new‘out of town'shopping centres．In the past，people often walked to shops near their home or went by bus．Now，many people drive to the new shopping centres．As a result，the small shops have disappeared and more people have to travel to do their shopping．
Critics say that Britain needs better and cheaper public transport．Transport in Britain is very expensive．An early morning train trip from Glasgow to London （about 600km） can cost about
￡100，for example．A short 15-minute bus trip can cost over￡1.00．
Many people are trying to reduce the use of cars in Britain．Some cities now have special bicycle paths and many people cycle to work．Some people also travel to work together in one car to reduce the pollution and the cost．
