题目内容
12．-Jim，how about going to the movie Mission Impossible IV tonight？-Well，I ______ it already．（ ）
| A． | see | B． | saw | C． | have seen | D． | will see |
分析 -吉姆，今晚去看电影"碟中碟4"怎么样？
-嗯，我已经看了．
解答 答案：C
根据already，可知应该用现在完成时态．already是现在完成时的标志词．现在完成时态表示过去发生或已经完成的动作对现在造成的影响或结果．或从过去已经开始，持续到现在的动作或状态．本题属于表示过去发生或已经完成的动作对现在造成的影响或结果，现在完成时态的构成：助动词have/has+过去分词，根据主语I，用have seen，故选：C．
点评 本题主要考查动词时态，做此类题目要注意时间状语、标志词．根据上下文所表达的含义，做出判断．同时更应记清时态的构成形式．就本题而言，主要考查现在完成时态．

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．
