LONDON —A British judge on Thursday sentenced a businessman who sold fake (假冒的)bomb detectors (探測器) to 10 years in prison, saying the man hadn’t cared about potentially deadly consequences.

It is believed that James McCormick got about $77. 8 million from the sales of his detectors — which were based on a kind of golf ball finder — to countries including Iraq, Belgium and Saudi Arabia.

McCormick, 57,was convicted (判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.

“Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people,’’ Judge Richard Hone told McCormick. “You have neither regret, nor shame, nor any sense of guilt.”

The detectors, sold for up to $ 42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they “l(fā)acked any grounding in science” and were of no use.

McCormick had told the court that he sold his detectors to the police in Kenya,the prison service in Hong Kong, the army in Egypt and the border control in Thailand.

“I never had any bad results from customers,” he said.

39. Why was McCormick sentenced to prison?

A. He sold bombs.                              B. He caused death of people.

C. He made detectors.                              D. He cheated in business.

40. According to the judge, what McCormick had done ________ .

A. increased the cost of safeguarding

B. lowered people’s guard against danger

C. changed people’s idea of social security

D. caused innocent people to commit crimes

41. Which of the following is true of the detectors?

A. They have not been sold to Africa.

B. They have caused many serious problems.

C. They can find dangerous objects in water.

D. They don't function on the basis of science.

42. It can be inferred from the passage that McCormick _________ .

A. sold the equipment at a low price

B. was well-known in most countries

C. did not think he had committed the crime

D. had not got such huge profit as mentioned in the text

【語篇解讀】本文是一篇記敘文,題材是新聞報道。本文報道了一條賣假冒炸彈探測器的商人被判10年徒刑的新聞。

段落

關(guān)鍵詞、句

大意推測

第一部分(Para. 1-3)

McCormick, 57,was convicted of cheats last month and sentenced Thursday at the Old Bailey court in London

新聞案件的簡介:57歲的McCormick上月被起訴詐騙并于周三在倫敦的Old Bailey court法庭被判刑。

第二部分(Para. 4)

cheating conduct, promoted a false sense of security, contributed to causing death and injury to innocent people

法官宣判:罪犯的欺騙行為增強了人們虛假的安全感并促使導(dǎo)致給無辜百姓帶來死亡和傷害。

第三部分(Para. 5-7)

But in fact they “l(fā)acked any grounding in science” and were of no use, sold…to… , never had any bad results

案件細節(jié)及當(dāng)事人的反訴:假冒炸彈探測器被銷往世界各地,但它根本沒有科學(xué)依據(jù),也毫無用處。罪犯狡辯假冒產(chǎn)品沒有給用戶帶來任何不良后果。

【解析】

39. D。細節(jié)理解題。難度:中等。問題是“為什么McCormick被判刑入獄”。根據(jù)問題中的關(guān)鍵詞sentenced to prison定位原文第一段。第一段說到McCormick是一位商人,生產(chǎn)了假冒的炸彈探測器,這是一種商業(yè)欺騙。選項D和其對應(yīng),為正確答案。

40. B。細節(jié)理解題。難度:難。問題是“根據(jù)法官的說法,McCormick的所為導(dǎo)致了什么樣的結(jié)果”。根據(jù)問題中的關(guān)鍵詞according to the judge定位第四段的第一句:your cheating conduct … promoted a false sense of security and … contributed to causing death and injury to innocent people(你的欺騙行為提高了人們虛假的安全感并助推給無辜百姓帶來死亡和傷害)。由此可見,McCormick的行為讓人們有了安全感,但這種安全并不真實。B “降低了人們防范危險的安全意識”符合此意,為正確答案。

41. D。判斷題。難度:難。問題是“下面哪種說法對探測儀來說是正確的”。

解題思路:根據(jù)問題中的關(guān)鍵詞detectors,把四個選項具體對應(yīng)到原文中一處。A對應(yīng)文章倒數(shù)第二段的最后一句he sold his detectors to the police in Kenya,the prison service in Hong Kong, the army in Egypt and the border control in Thailand。該句中的Kenya是非洲的肯尼亞,否定了A的說法。B對應(yīng)第一段第一句“the man hadn’t cared about potentially deadly consequences”,法官只說罪犯沒有關(guān)注潛在的致命后果,而不是已經(jīng)導(dǎo)致嚴(yán)重的問題。C對應(yīng)第五段的第一句話“were said to be able to find such dangerous objects as bombs under water and from the air”提示,探測儀的功能只是據(jù)說,而不一定真的具備找到水中危險物品的功能。選項D定位第五段的最后一句“in fact they ‘lacked any grounding in science’ and were of no use可知,這種探測儀沒有科學(xué)根據(jù),也毫無用途,和D“沒有科學(xué)根據(jù)的工作原理”相吻合,故最佳答案是D。

42. D。推理判斷題。難度:中等。

解題思路:返回原文,將選項與原文一一進行比較

本題主要考查第四段和第七段。A“以低價銷售設(shè)備”與原文第四段第一句不符,因為該句提到法官指控McCormick通過賣一些無用的設(shè)備來巨額利潤。B“在大多數(shù)國家很有名”與文中提到的區(qū)區(qū)幾個國家和地區(qū)Iraq,Belgium,Saudi Arabia,Kenya,Hong Kong,Egypt和Thailand購買他的探測儀不符。C“認為他沒有犯罪”和第七段對應(yīng),其中他所說的“I never had any bad results from customers”和C符合,C是正確答案。D“他沒有賺取文中提到的那么大利潤”在原文沒有語言根據(jù)。
