单选题Almost Human? Scientists are racing to build the world's first thinking robot .This is not science fiction: some say they will have made it by the year 2020, Carol Packer reports. Machines that walk, speak and feel are no longer science fiction. Kismet is the name of an android (机器人) which scientists have built at the Massachusetts Institute of Technology (MIT). Kismet is different from the tradition robot because it can show human emotions. Its eyes, Ears and lips move to show when it feels happy, sad or bored. Kismet is one of the first of a new generation of androids-robots that 100k like human beings, which can imitate human feelings. Cog, another android invented by the MIT, imitates the action of a mother. However, scientists admit that so far Cog has the mental ability of a two-year-old. The optimists say that by the year 2020 we will have created humanoids (机器人) with brains similar to those of an adult human being. These robots will be designed to look like people to make them more attractive and easier to sell to the public. What kind of jobs will they do? In the future, robots like Robonaut, a humanoid invented by NASA, will be doing dangerous jobs, like repairing space stations. They will also be doing more and more of the household work for US. In Japan, scientists are designing androids that will entertain US by dancing and playing the piano. Some people worry about what the future holds: will robots become monsters? Will people themselves become increasingly like robots? Experts predict that more and more people will be wearing micro-computers, connected to the Internet, in the future. People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets (小装置).

单选题Wrongly Convicted Man and His Accuser Tell Their Story 　　NEW YORK,NY, January 5,2010. St.Martin’s Press has announced the release of the paperback edition of Picking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.” 　　The story began in 1987, in Burlington, North Carolina, with the rape of a young while college student named Jennifer Thompson. During her ordeal, Thompson swore to herself that she would never forget the face of her rapist, a man who climbed through the window of her apartment and assaulted her brutally.________(46) When the police asked her if she could identify the assailant(袭击者)from a book of mug shots, she picked one that she was sure was correct, and later she identified the same man in a lineup. 　　Based on her convincing eyewitness testimony, a 22-year-old black man named Ronald Cotton was sentenced to prison for two life terms. Cotton’s lawyer appealed the decision, and by the time of the appeals hearing, evidence had come to light suggesting that the real rapist might have been a man who looked very like Cotton, an imprisoned criminal named Bobby Poole._______ (47) Jennifer Thompson looked at both men face to face, and once again said that Ronald Cotton was the one who raped her. 　　Eleven years later, DNA evidence completely exonerated(证明……清白)Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. ________(48) “The man I was so sure I had never seen in my life was the man who was inches from my throat, who raped me, who hurt me, who took my spirit away, who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions was absolutely innocent.” 　　_______ (49) Remarkably both were able to put this tragedy behind them, overcome the racial barrier that divided them, and write a book, which they have subtitled “Our memoir of injustice and redemption.” 　　Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly______ (50)” A. Another trial was held. B. I cannot begin to imagine what would have happened had my mistaken identification occurred in a capital case C. Thompson was shocked and devastated. D. Jennifer Thompson decided to meet Cotton and apologize to him personally. E. During the attack, she made an effort to memorize every detail of his face , looking for scars , tattoos (纹身) or other identifying marks. F. Many criminals are sent to prison on the basis of accurate testimony by eyewitnesses.
