On August 28th, at a presentation over the Internet, Mr. Musk showed off the progress of his firm, Neuralink. The highlight was the appearance of Gertrude, a pig with a chip implanted（植入） into her brain. Reading the brain's electrical signals, a technique called electroencephalography (EEG), started over 100 years ago and is now routine. It generally involves placing non-invasive electrodes（非侵入式电极） on the scalp（头皮）, though it sometimes requires the invasive insertion wires into the scalp or the brain. Non-invasive EEG provides useful information, and can even be used to do things like playing computer games. Invasive EEG offers more accurate readings from the nerve cells in the brain, though at greater risk because of the surgery involved. The device Gertrude carries, known technically as a brain-computer interface （接口）, carries invasiveness one stage further by making the EEG recorder a potentially permanent implant. Along with this improved interface, Neuralink has built a robot that will implant it. To do so, the robot first takes a high-resolution scan of the recipient's brain. Using this, it is able to sew the electrode threads into place with a precision that avoids any blood tubes in the area, which reduces the risk of damage during surgery. The robot can put the interface in place in less than an hour. General anesthesia（麻醉） is not needed for the procedure One challenge the firm wants to tackle is sending electrical signals into the brain. Mr. Musk says this will require a range of inputs including delicate stimulation and large amounts of currents. The point of doing so will be to establish two-way communications. This could allow entirely new areas of treatment to be explored. Besides epilepsy （癫痫） prevention, such brain stimulation might also work to treat depression. More important in the long run. It is also essential to Musk's vision of widespread engagement between people and machines. This, he hopes, will result in a future where memories can be downloaded and stored elsewhere, and humans can form a relationship with AI that is mutually dependent and beneficial. Not everyone is impressed. Critics worry that Neuralink is too secretive, and that Mr. Musk's vision promises more than he can deliver. He does, though, have a record d of doing what he says he is going to, despite the fact that sometimes not as rapidly as he says he will. He more or less single-handedly introduced battery-electric cars to the market and he built a successful space-rocket business out of nothing. Brains are a lot more complicated than cars, and even than rocket science. But do not bet against the coming into being at some point of the Musk vision of brains and computers working together directly.1.What can we learn about EEG? A.EEG requires the insertion of electrodes.B.Non-invasive EEG is superior in safety and speed.C.Invasive EEG functions better in reading nerve cells.D.EEG can be updated by using the brain-computer interface.2.In Paragraph 3, the author describes the implantation to show .A.the advantages of using the robotB.the simplicity of the procedureC.the improvement of the interfaceD.the possible risks of the surgery3.According to the text, .A.Musk achieves more in brain study than in rocket scienceB.brain stimulation is crucial for people-machine interactionC.new methods of treatment have been researched and createdD.the firm has difficulty finding the right kind of input for brains4.What's the author's attitude towards Musk's vision?

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.

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.

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
