Recently，a group of Chinese scientists took things a step further by using 3 D printing technology to create realistic models of human organs.In the past，it was challenging to create a single material that could print all human organs because they are very different from each other.The Chinese research team started by using hydrogel，a soft gel-like material，as the main material. Scientists use hydrogel and other materials for printing human organs.They have various hardness，such as our bones being the hardest and our brains being the softest.To copy the hardness of human organs，the researchers added metallic elements to the hydrogel and regulate their ratio.In this way，some models can be hard，like the bone，and some can be soft.However，the structure inside the human body is also unbelievably complicated，even in the same organ，different parts require different levels of hardness.To make sure the printing results are correct，the team used a specific technology called light-curing in the 3 D printing process.A special light was placed under the printing machine，causing the gel to become strong right after it was printed. ___________.They usually cannot be used for organ transplanting directly，because human cells are likely to recognize them as "enemies" and start to fight against them.These days，scientists are working on bio-printing：using 3 D printing technology to build up various types of cells and materials layer by layer.After that，the printed product will be more acceptable to grow inside the human body.However，this method is in development，and experts are still on the way.They hope it will be used in the medical field within a few years，according to CNN. These 3 D printed organ models are used in various fields，such as testing medical tools and presenting operations.Compared to live organs and animal models，they are also ethically acceptable since they are man-made and printed.To some degree，they can help researchers develop new treatments more efficiently，due to their lower relative cost，commented the Alliance of Advanced Biomedical Engineering website.（1）In the past，what was the main challenge when printing human organs？ BA．The cost of printing organs was too high to afford.B．It was hard to use one material for different organs.C．There were too many organs for researchers to print.D．The printing technology was still in the development.（2）The research team make the printing results right by C.A．adding more gel in the process of printingB．controlling the number of metallic elementsC．using light-curing technology while printingD．putting a special light over the printing machine（3）Which sentence can be put in the " A" in Paragraph 3？A．However，the hydrogel materials are not perfectB．The hydrogel materials are quite expensive to developC．Besides，the hydrogel materials have more advantagesD．The hydrogel materials have been applies in many ways（4）From the passage，we know that hydrogel is A.A．used as a main materialB．a hard material like metalC．accepted by human bodiesD．invented by Chinese experts

Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. In the ever-changing 21st century, even the word “habit” carries a negative meaning. So it seems contradictory（矛盾的）to talk about habits in the same context as innovation（创新）. But brain researchers have discovered that when we consciously develop new habits, we create parallel paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks. But don't bother trying to kill off old habits; once those ruts of procedure are worn into the brain, they're there to stay. Instead, the new habits we deliberately（故意地）press into ourselves create parallel pathways that can bypass those old roads. “The first thing needed for innovation is attraction to wonder,” says Dawna Markova, author of The Open Mind. “But we are taught instead to 'decide', just as our president calls himself 'the Decider'.” She adds, however, that “to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.” “All of us work through problems in ways of which we're unaware,” she says. Researchers in the late 1960s discovered that humans are born with the ability to approach challenges in four primary ways: analytically, procedurally, collaboratively（合作地）and innovatively. At the end of adolescence（青春期）, however, the brain shuts down half of that ability, preserving only those ways of thought that have seemed most valuable during the first decade or so of life. The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently（本质上）use our innovative and collaborative ways of thought. “This breaks the major rule in the American belief system—that anyone can do anything,” explains M. J. Ryan, author of the 2006 book This Year I Will…and Ms. Markova's business partner. “That's a lie that we have preserved, and it encourages commonness. Knowing what you're good at and doing even more of it creates excellence.” This is where developing new habits comes in. 1．Brain researchers have discovered that ＿＿＿＿. A．the forming of new habits can be guided B．the development of habits can be predicted C．the regulation of old habits can be transformed D．the track of new habits can be created unconsciously 2．The underlined word “ruts” in Paragraph 4 is closest in meaning to ＿＿＿＿. A．zones B．connections C．situations D．tracks 3．Which of the following statements most probably agrees with Dawna Markova's view? A．Decision makes no sense in choices. B．Curiosity makes creative minds active. C．Creative ideas are born of a relaxing mind. D．Formation of innovation comes from fantastic ideas. 4．Ryan's comments suggest that the practice of standard testing ＿＿＿＿. A．prevents new habits from being formed. B．no longer emphasizes commonness. C．innovative and collaborative ways of thought are widely used. D．follow the American belief system.

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
