SECTION B PASSAGESDirections: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文：Often, your mind is challenged by a flood of pop culture messages, peer pressure, and overscheduled lives that leave little time for good reflection. So, it’s easy to forget that learning values and character at home is as important as any schoolwork or after-school activity. In the real world of jobs and career, people are judged by two standards: their professional skills and their personal personalities. While grade school, high school, and college can teach skills and proficiency, it’s up to parents to teach children the qualities that make for success in the real world —diligence, a cooperative attitude, creativity, optimism and honesty. Schools —particularly colleges —don’t focus on these issues. That’s the job of the parents, so take the responsibility seriously. Send your kids into the world ready to handle not only the tasks of life but also its barriers, social obstacles, and disappointments with skill and character. Children need personal reliability and morals as much as any adult. Bullies will always be around, tasks won’t always be assigned fairly, the good guys won’t always win, and money won’t always be in plenty supply. Exposing children to the rough realities of life isn’t cruel; giving them that experience and coaching them through is part and parcel of raising kids to have courage, flexibility and honor. You really can’t start too soon. After all, if you don’t guide and shape your children, who will?
12．School systems usually center on______
A．professional capacities.
B．personal personalities.
C．sense of responsibility.
D．standards of proficiency.
正确答案：A
解析：细节题。

由第二段第二句话“While grade school，high school，and college can teach skills and proficiency”可知，学校以专业技能为中心。

知识模块：短文
13．From this passage, we can infer that______
A．parents should take the duty to handle the tasks of their children.
B．children’s personal reliability and morals are the same as any adult’s.
C．children should be educated to be well prepared for the real world.
D．parents should not guide and shape their children at home too soon.
正确答案：C
解析：事实推断题。

由第二段最后一句话可知，父母应把孩子融入真实的世界，让孩子们“handle the tasks”，故A项错误；由第三段第一句话可知，成人和孩子所需的personal reliability and morals是一样多的，但这不是说他们所需的personal reliability and morals一样，因此B项不正确；由第三段可以推知，应该让孩子接受各方面的教育，即让他们对现实世界有充分的准备，C是正确的；第四段第一句话含有句式“can’t…too．．．”，其句子的意思是“你应该立即开始”，这与D项的表述正好相反。

知识模块：短文
14．The passage is particularly intended for______
A．school students.
B．parents.
C．social workers.
D．educators.
正确答案：B
解析：推理题。

由第二段最后一句话中的“your kids”可以推知，所以答案选B。

In 1927 sound was added to the previously silent film, and thus one of the theaters principal claims to superiority vanished. In 1929 a serious economic depression began, Since audiences could go to the movies for a fraction of What it cost to see a play, theater going became a luxury Which few could afford, especially as the depression deepened.

听力原文：In the past three decades, steroids have been becoming a serious problem more than ever in the athletic field. Steroids are anabolic drug “to build” growth hormones that include the male sex hormones and female sex hormones. Steroids were first developed for medical purposes. They’re used in controlling inflammation, strengthening weakened hearts, preventing conception, and alleviating symptoms. Unfortunately, research has shown that steroids have been abused in almost every kind of sport. Although steroids contribute to a muscular body, usage should remain illegal because they physically deteriorate and mentally destroy the body. Many people are fascinated about steroids because of their ability to build up the body. Whether taken by injection or the pill it increases strength and endurance. Steroids also help in the healing process of muscular tissue by first injuring them, then the muscles heal quicker adding more fiber increasing their bulk. Many athletes turn to steroids more often because they’re cheaper than marijuana or cocaine. Steroids are also very hard to trace because of their water base composition. They can pass through the body withintwo days. All these benefits of steroids help athletes become more competitive and increase their chance of being a winner. Of course everybody wants better biceps and triceps but when using steroids to achieve this goal there is a large price to pay.

而词组contribute to是中性的词组，根据上下文可以表示“贬”也可以“褒”的意思，如做出贡献、造成、促成等。

20．Which of the following is NOT true, according to the benefits that steriods is supposed to have?
A．Steroids heals the process of blood and tissue.
B．Steroids does not stay in the body for long.

SECTION C NEWS BROADCASTDirections: In this section, you will hear several news items. Listen to them carefully and then answer the questions that follow.
听力原文：Scientists have borrowed a technique from biology to calculate the age of our mother tongue. They say the Indo-European languages emerged more than 9,000 years ago. Languages evolve much as animals do, words gradually change over time just as gene evolves in the living beings. So a biologist in New Zealand decided to use the mathematical tools developed to estimate the age of living species to study the evolution of our mother tongue. He and a colleague studied 2,400 words
in more than 80 so-called Indo-European languages. The researchers now report in Nature that these languages started out as a common tongue more than 9,000 years ago. That’s consistent with other research dating our root language. According to that hypothesis, Indo-Europeans started out in Anatolia, which is present-day Turkey, and spread through Europe as farmers settled the land.
22．How do scientists estimate the age of language?
A．By studying animals’ evolution.
B．By studying human genes.
C．By using mathematical tools.
D．By using the age of living species.
正确答案：C
解析：细节判断题。

听本段新闻时，一定要注意原话的表述内容，不能只凭借只言片语来作答，那样往往会落人出题人的陷阱。

新闻的第一句话是说：“科学家们借用一种生物学的技术计算出了人类母语的历史。

”关键的点在于calculate这个单词，而不是biology，所以不能选A和D两项。

新闻中的另外一个句子表述要更加清晰，即“一位新西兰生物学家决定用能推测出生物种类存在时间的数学方法来研究人类母语演变的历史”。

根据这点．我们能够确定正确的选项是C项。

听力原文：The International Monetary Fund has told governments across the world that further action is needed to help return the global financial system to stability. In a fresh estimate of the scale of the problem, the IMF says global losses on toxic assets could total four trillion dollars. This report does identify what it calls some early signs of stabilization in financial systems, but there are not many of them. And the IMF says further action will be needed if they’re to be sustained. In two key areas, it says that progress by governments has been piecemeal and reactive, dealing with the problem assets held by financial institutions and how to handle banks that need extra capital.
