Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.

A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic snow were declining.

In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.

In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.

Many scientists had believed that the lead would stay in soil and snow for a longer period.

The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.

Scientists say both studies demonstrate that certain parts of the ecosystem respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.

57.　 The study published in the journal Nature indicates that ________.

A.　 the Clean Air Act has not produced the desired results

B.　 lead deposits in arctic snow are on the increase

C.　 lead will stay in soil and snow longer than expected

D.　 the US is the major source of lead pollution in arctic snow

58.　 Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US　 _____ .

A.　 was discouraged B.　 was enforced by law

C.　 was prohibited by law　　　　　 D.　 was introduced

59.　 How did scientists discover the source of lead pollution in Greenland?

A.　 By analyzing the data published in journals like Nature and Ambio.

B.　 By observing the lead accumulations in different parts of the arctic area..

C.　 By studying the chemical elements of soil and snow in Northeastern America.

D.　 By comparing the chemical compositions of leaded gasoline used in various countries.

60.　 The authors of the Ambio study have found that ________.

A.　 forests get rid of lead pollution faster than expected

B.　 lead accumulations in forests are more difficult to deal with

C.　 lead deposits are widely distributed in the forests of the US

D.　 the upper layers of soil in forests are easily polluted by lead emissions

　　　 A.　 Join a Class, Sports Team, or Club

　　　 B.　 Eat alone in Public

　　　 C. Talk to your Neighbors

　　　 D.　 Keep an Open Mind

　　　 E.　 Take Pictures

　　　 F.　 Meet People through your Job

　　　 What could seem like an exciting, fresh new start can also be a huge pain: moving to a new city. Whether you decided to pick up and go because of a job offer, or simply wanted to get away from your old town, moving to a brand new city allows for a chance to start a new----brand new image and all.

　　　 But the big move can also be terrible; especially if you don’t know anyone in the place you now call home.

　　　 So in order to create your new image, you’ll need a whole new crew. Here’s how to meet some of those new people.

61. _____________

One of the great things about taking pictures at an event or party is that it gives you an excuse to get in touch with the person later. Everybody loves seeing pictures of himself, and it’s very easy after taking a picture to say “Are you on Facebook?” or “If you’d like I can email it to you.”

This can be the seed that leads to new connections. The next time you hear about a fun event email your new contacts to let them know about it.

62. _____________

　　　 If you don’t know anyone in a new city, it can be tempting to order take-out and retreat back to your lonely apartment or hotel room. Instead, try eating by yourself in public as often as possible.

You might feel self-conscious eating by yourself but it has an important benefit: you are much easier to approach when you are alone. People may be afraid of interrupting you or being rude if you are in a conversation with someone else.

Bring a book or newspaper to read (this will make you feel less self conscious). Plus, having an interesting book with you will give others an excuse to start a conversation if they’ve read it.

63. _____________

　　　 Yoga, salsa dancing, volleyball, jogging, Toastmasters (a Public Speaking club), a class for work, martial arts, etc. Take up a new hobby or continue an old one!

These are all great places to meet new people, primarily because you will be forced to see the same people over and over again in the class. You will automatically make friends with them if you have a common interest and are forced to see each other again.

64. _____________

　　　 You’re most likely to meet people at your office, so make sure to chat with the guy who sits at the cubicle next to yours, and try to make casual conversation with everyone from your manager to the guy who fixes the photocopy machine. This is your chance to spread yourself thick and make that extra effort, since you’re still considered “the new guy” and will be getting a certain degree of attention. Use it to your advantage.

　　　 Try to eat at the cafeteria rather than at your desk, and take people up on their offer to join them for lunch or go to the local happy tour; even if some of these people aren’t exactly “your type”, they might have friends that you’d love to hang with.

65. _____________

　　　 You may have never even known your previous neighbors, but home is a great place to start meeting people. There could be a whole pool of cool people in your apartment building or on your street, especially if you’re in the right area. So when you see some one from your apartment building getting their mail or a guy washing his car in his driveway, break the ice by asking a question that shows you’re new in town, like where the local video of liquor store is, and where the hot clubs are. Never overlook those that live next door, as they can always come in handy when you need them.

LONDON —A British judge on Thursday sentenced a businessman who sold fake (假冒的）bomb detectors (探测器) 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 “lacked 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

【语篇解读】本文是一篇记叙文，题材是新闻报道。本文报道了一条卖假冒炸弹探测器的商人被判10年徒刑的新闻。

【解析】

39. D。细节理解题。难度：中等。问题是“为什么McCormick被判刑入狱”。根据问题中的关键词sentenced to prison定位原文第一段。第一段说到McCormick是一位商人，生产了假冒的炸弹探测器，这是一种商业欺骗。选项D和其对应，为正确答案。

40. B。细节理解题。难度：难。问题是“根据法官的说法，McCormick的所为导致了什么样的结果”。根据问题中的关键词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（你的欺骗行为提高了人们虚假的安全感并助推给无辜百姓带来死亡和伤害）。由此可见，McCormick的行为让人们有了安全感，但这种安全并不真实。B “降低了人们防范危险的安全意识”符合此意，为正确答案。

41. D。判断题。难度：难。问题是“下面哪种说法对探测仪来说是正确的”。

解题思路：根据问题中的关键词detectors，把四个选项具体对应到原文中一处。A对应文章倒数第二段的最后一句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。该句中的Kenya是非洲的肯尼亚，否定了A的说法。B对应第一段第一句“the man hadn’t cared about potentially deadly consequences”，法官只说罪犯没有关注潜在的致命后果，而不是已经导致严重的问题。C对应第五段的第一句话“were said to be able to find such dangerous objects as bombs under water and from the air”提示，探测仪的功能只是据说，而不一定真的具备找到水中危险物品的功能。选项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，这种探测仪没有科学根据，也毫无用途，和D“没有科学根据的工作原理”相吻合，故最佳答案是D。

42. D。推理判断题。难度：中等。

解题思路：返回原文，将选项与原文一一进行比较。

本题主要考查第四段和第七段。A“以低价销售设备”与原文第四段第一句不符，因为该句提到法官指控McCormick通过卖一些无用的设备来巨额利润。B“在大多数国家很有名”与文中提到的区区几个国家和地区Iraq，Belgium，Saudi Arabia，Kenya，Hong Kong，Egypt和Thailand购买他的探测仪不符。C“认为他没有犯罪”和第七段对应，其中他所说的“I never had any bad results from customers”和C符合，Ｃ是正确答案。Ｄ“他没有赚取文中提到的那么大利润”在原文没有语言根据。

 In the dark forests ________ some large enough to hold several English towns.

   A. stand many lakes                                    B. lie many lakes

   C. many lakes lie                    D. many lakes stand

【详解】本题考查倒装结构，完全倒装。同时stand 和lie的区别。stand是突出的，lie是平躺的，湖不可能是突出的，所以此题应该选择lie。

A Love Note To My Mom

When I was a little girl, I would often follow you as you modeled (做模特) for fashion magazine. It was years later that I finally understood what role modeling 36 in your life. I know little that you were 37 every penny you earned to go to 38　 school.

I cannot thank you enough for 39 you told me one autumn afternoon when I was nine. After finishing my homework, I wandered into the dining room where you were buried 40　 piles of law books. I was __41　 .Why were you doing what I do—memorizing textbooks and studying for 42　 ? When you said you were in law school, I was more puzzled. I didn’t know Moms__ 43　 be lawyers too. You smiled and said,“In life, you can do anything you want to do.”

Though I was young, your words kept 44 in my ears. I watched as you faced the 45 of completing your studies, starting companies with Dad, while still being a 46 and a Mom of five kids. I was tired just watching you 47 . With your wise words in my 48 mind, I suddenly felt free to dream. My whole world 　__49 .I set out to live my life filled with__ 50 __ , seeing endless possibilities for personal achievements.

Your words became my motto. I 51　 found myself in the position of being either the first (woman doctor in Maryland Rotary) 52 one of the few women (top medical reporters) in my field. I gained strength every time I said , “Yes, I’ll try that.”

Encouraged by your 53 , I have forged ahead (毅然前行) with my life’s journey, less afraid to make mistakes, and 54　 meeting each challenge. You did it, and now I’m 55 it. Sorry, got to run. So much to do, so many dreams to live.
