Question

                                           C 

              Crime-fighdng technology is getting more sophisticated(高級(jí)的) and rightly so. The police need to be equipped for the 21st century. In Britain we ve already got the world's biggest DNA database. By next year,the state will have access to the genetic(基因的) data of 4. 25 million people: one British-based person in 14.Hundreds of thousands of those on the database will never have been charged with a crime.

              Britain is also reported to have more than four million CCTV (closed circuit television) cameras.

There's a continuing debate about the effectiveness of CCTV. Some evidence suggests that it's helpfiil in reducing shoplifting and car crime.It has also been used to successfully identify(識(shí)別)terrorists and murderers. However,many claim that better lighting is just as effective when it comes to preventing crime, and that cameras could displace (轉(zhuǎn)移) crime. A police report said that only one crime was solved for every l,000 cameras in London in 2007. In short,there's conflicting evidence about the effectiveness of cameras,so it's   likely that the debate will continue.

              Professor Mike Press,who has spent the past decade studying how design can contribute to crime reduction,said that,in order for CCTV to have any effect,it must be used in a targeted way.

Most cameras that simply record city centres continually — often not being watched 一 do not produce results. CCTV can also have the opposite effect of that intended,by giving citizens a false sense of safety and encouraging them to be careless with property(財(cái)產(chǎn)) and personal safety.

              Professor Press said:“All the evidence suggests that CCTV alone makes no positive influence on crime reduction and prevention at all. The weight of evidence would suggest' the investment is more or less a waste of money unless you have lots of other things in place.”He believes that much of the increase is driven by the marketing efforts of safety companies who promote the crime-reducing benefits of their products. He described it as a “l(fā)azy approach to crime prevention" and said that authorities should instead be focusing on how to change the environment to reduce crime.

C篇(熱點(diǎn)話題)

本文是說(shuō)明文。英國(guó)有超迓四百萬(wàn)個(gè)閉路電視攝像頭，這能否有效減少犯罪呢？

28. A. 細(xì)節(jié)理解題。由第一段中的 Crime-fighting technology is getting more sophisticated 和 Hundreds of thousands of those on the database will never have been charged with a crime 可知，英國(guó)建立一個(gè)龐大的DNA數(shù)據(jù)庫(kù)是為了打擊犯罪。

29. C. 段落大意題。由第二段中的some evidence suggests that it's helpful in reducing shoplifting and car crime 和However,many claim that ... displace crime 以及 there's conflicting evidence about the effectiveness of cameras 可知，人們對(duì)CCTV攝像頭的作用觀點(diǎn)不一。

30. B. 觀點(diǎn)態(tài)度題。由最后一段中的All the evidence suggests that CCTV alone makes no positive influence …the investment is more or less a waste of money 可知，Mike Press 教授認(rèn)為CCTV在減少和預(yù)防犯罪方面沒有產(chǎn)生積極的作用，他甚至覺得這種投資是浪費(fèi)錢。

31. A. 細(xì)節(jié)理解題。由最后一段中的authorities should instead be focusing on how to change the environment to reduce crime可知，Press教授認(rèn)為，官方應(yīng)該重點(diǎn)關(guān)注如何改變環(huán)境來(lái)減少犯罪。
