　　(2024·江西六校聯(lián)考)

　　“When I grow up, I want to be...”

　　Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.

　　However, it seems career options aren't only based on personal taste. In a survey carried out by teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the U．K. in May 2011 by job website monster.co.uk, in which medicine was the top choice among U．K. teenagers aged between 13 and 17.

　　Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high-profile professions is often seen as a sign of upward social mobility.

　　It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the U．K. tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”．

　　However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens' survey discovered, a variety of unconventional jobs—coffee shop owner, gourmet (美食家), waiter at a fast food restaurant—are among teenagers' career choices. They can be equally interesting and rewarding jobs.

　　With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.

　　語篇解讀：本文是一篇議論文。文章論述了青少年心中最理想的職業(yè)。所有的職業(yè)生涯道路需要特殊的教育和培訓(xùn)，我們對自己的特長既要客觀現(xiàn)實又要樂觀自信。

　　1．What is the passage mainly about?

　　A．Choosing a good job is very important.

　　B．Careers in teenagers' mind.

　　C．Teenagers in the U．K. like doctors.

　　D．The choice of career needs challenge.

　　答案：A　主旨大意題。本文是圍繞“青少年心中最理想的職業(yè)”展開論述的，故選A項。

　　2．According to the article, all of the following are the benefits of being a doctor EXCEPT ________.

　　A．respect from others B．upward social mobility

　　C．high pay D．the oldest profession

　　答案：D　細節(jié)理解題。根據(jù)文章第四段關(guān)鍵詞“the most esteemed members of society, make good money, a sign of upward social mobility.”可知，A、B、C三項提到了，D項在文中沒提到。

　　3．What do youngsters think is increasingly becoming one of the most important indicators of a successful career?

　　A．Prestige. B．Fulfillment.

　　C．Happiness. D．Wealth.

　　答案：D　細節(jié)理解題。根據(jù)第五段最后一句“Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”．”可知，財富正日益成為判斷成功職業(yè)的最重要指標(biāo)。故選D項。

　　4．What can we learn from the last paragraph?

　　A．According to your particular talents and skills, you can choose your favorite career.

　　B．Specific education and training can help get a good job.

　　C．Whatever career you choose, you should balance optimism and confidence with being realistic about your particular talents and skills.

　　D．Responsibility is the most important when you choose a good job.

　　答案：C　推理判斷題。根據(jù)文章最后一段“...you have to learn to balance optimism and confidence with being realistic about your particular talents and skills...”可知，無論從事什么職業(yè)，我們對自己的特長既要客觀現(xiàn)實又要樂觀自信。故選C項。

　　(2024·新課標(biāo)全國Ⅱ·B)

　　Since the first Earth Day in 1970，Americans have gotten a lot “greener” toward the environment. “We didn't know at that time that there even was an environment, let alone that there was a problem with it，” says Bruce Anderson, president of Earth Day USA.

　　But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times，” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.

　　According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “green thinking” has become part of practices.

　　Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

　　Twenty-five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “ Until we do that, nothing else will change！” says Bruce Anderson.

　　語篇解讀：本文是一篇記敘文，作者講述了自從1970年第一個地球日實施以來，美國環(huán)境問題得到了很大程度的改善。

　　5．According to Anderson, before 1970, Americans had little idea about ________.

　　A．the social movement

　　B．recycling techniques

　　C．environmental problems

　　D．the importance of Earth Day

　　答案：C　 細節(jié)理解題。由第一段第二句話“We didn't know at that time there even was an environment, let alone that there was a problem with it，” says Bruce Anderson, president of Earth Day USA. 那時我們不知道有環(huán)境，更不用說環(huán)境還有問題。故選C項。

　　6．Where does the support for environmental protection mainly come from?

　　A．The grass-roots level.

　　B．The business circle.

　　C．Government officials. D．University professors.

　　答案：A 　細節(jié)考查題。由第二段第二句話“Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement.”尤其是成千上萬的草根美國人參加了這一運動。所以對于環(huán)保的支持主要來自草根階層，故選A項。

　　7．What have Americans achieved in environmental protection?

　　A．They have cut car emissions to the lowest.

　　B．They have settled their environmental problems.

　　C．They have lowered their CO levels in forty cities.

　　D．They have reduced pollution through effective measures.

　　答案：D 　細節(jié)判斷題。由第三段中“...emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons.”可知A項中的“把汽車排放降到最低”錯誤；再結(jié)合第二句可知，C項錯誤；由“Although serious problems still remain and need to be dealt with, the world is a safer and healthier place”可知B項錯誤D項正確。

　　8．What is especially important for environmental protection according to the last paragraph?

　　A．Education.

　　B．Planning.

　　C．Green living. D．CO reduction.

　　答案：A　主旨大意題。文章最后一段講述了教育對于環(huán)保的意義，并且最后Anderson說的話“Until we do that, nothing else will change! ”可知答案選A。

　　Ⅳ.短文填空

　　根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

　　__1__ Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

　　The ridge (隆起) structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. __2__ Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

　　Finger-prints can be made very easily with printer's ink. They can by recorded easily. __3__ Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. __4__

　　When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.

　　__5__ Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
