2.阅读理解There is no doubt that man is a member of the animal kingdom.Anyone who has thought about this fact seriously must have wondered how it has come about that man has achieved a position so supreme(最高的) among the myriad(无数的) kinds of animal life.Two characteristics of man, in comparison with all other animals, that stand out above all others are the creation and use of tools and the development and use of language.Since no other animals have achieved these abilities, it must be assumed that man’s evolutionary development led to his capacity to create and use tools and to devise and use language.Once these abilities and practices evolved, they probably became driving forces in the further evolution of man.Those members of the species who become most proficient(精通的) in the fabrication of tools and in the command of language and thought would tend to survive and maintain their kind for good, at the expense of those of lesser ability.11.Which of the following statements best expresses the main idea of the passage?()A.Tools and language are either the effects or the causes of human evolution.B.No other animals have achieved human abilities.C.Among the animals, only man is able to use tools and language.D.Man owns his capacity to making use of tools and language.12.“Animal kingdom” in the passage refers to ().A.the place where all animals liveB.the animal societyC.all kinds of animals, including manD.the forest with animals13.One important condition for man’s evolution is() .A.the animal kingdomB.a supreme positionC.the myriad kindsD.his natural capacity14.The phrase “come about” in the passage is likely to mean ________.A.happenedB.appearedC.arrivedD.succeeded15.The last sentence suggests that() .A.those of lesser ability would be very expensiveB.in order to survive, man has to sacrifice some other animalsC.those who become proficient in making tools can speak wellD.language and thought could be acquired by man

    Practice 8  You should spend about 40 minutes on this task.  Write about the following topic:  Some people think people have benefited from modern communications technology, but other people think some people have not benefited at all. To what extent do you agree or disagree?  You should write at least 250 words.

    正确答案: 【参考范文】
    Daily communication tools make the distance between people shrink. There are various ways such as mobile phones, Facebook, Twitter and E-mail which changes our life from daily life to work style. As for the dramatic and rapid changes, people in all walks of life hold different opinions. Personally, it is a must to be tolerant of the new technological innovations.
    It is undeniable that all these high-tech tools can alienate the virtual interpersonal relationship that exists between people. If we want to tell somebody something, we do not have to really see him, and we can send a short message, a E-mail, or leave one on Facebook. Regardless of the convenience, face-to-face conversations are still one of the best ways to understand each other.
    High technologies provide us with more choices which can yield higher efficiency, which can be illustrated from three perspectives. Firstly, it is a useful time-saver for people greatly enjoy social life. Social network enable them to spare the trouble of heavy traffic in rush hours when they need to have contact with friends. Secondly, it is also a money-saver. Compared with the high cost of an official visit to someone or some place, chatting on-site or through telephone is much cheaper. If each company has an E-conference system, information sharing should never be a daydream in the era of information. Lastly, and most importantly, with the great help of new inventions, people may communicate with others without being limited to geographical difference. Namely, no matter where one stays, he or she can get in touch with people on the Internet at any time.
    In summary, modem technologies are excellent assistants of our life and work, so it is wise to accept them and make full use of them properly.

    Paleontologists hypothesize that modern birds evolved from the family of dinosaurs that included Tyrannosaurus rex. This hypothesis would be strongly supported if evidence that dinosaurs from this family had a body covering resembling feathers could be found, but so far no such evidence has been found.  Which of the following, if true, would most help the paleontologists explain why no evidence of feathered dinosaurs has yet been found?
    A

    Fossilized dinosaurs have shown many birdlike characteristics, such as bone structure and winglike arms.

    B

    If birds are in fact the descendants of dinosaurs, then it can be argued that the dinosaurs never really died out.

    C

    Flying dinosaurs such as the Pteranodon, which is not thought to have been related to modern birds, do not appear to have had feathers.

    D

    Soft tissues such as skin and feathers do not fossilize like bones, and therefore are far less likely to have left permanent evidence in the fossil record.

    E

    The thousands of dinosaur fossils excavated by paleontologists represent only a tiny fraction of the billions of dinosaurs that once lived.

    问答题
    Almost all Americans want to be democratic, but many Americans are confused about what, exactly, democracy means. How do you know when someone is acting in a democratic or an undemocratic way? Recently several groups have spoken out with particular bitterness against the kind of democracy that means equal opportunity for all, regardless of race or national origin. They act as if all human beings did not belong to one species, as if some races of mankind were inferior to others in their capacity to learn what members of other races know and have invented. Other extremists attack religious groups—Jews or Catholics--or deny the right of an individual to be an agnostic. One reason that these extremists, who explicitly do not want to be democratic, can get a hearing even though their views run counter to the Constitution and our traditional values is that people who do want to be democratic are frequently muddled.

    正确答案:
    几乎所有的美国人都崇尚民主,但是许多美国人并没有搞清民主到底指的是什么。怎么知道某人的行为是民主的还是不民主的呢?最近,一些团体愤愤不平地反对民主,即不分种族国籍,人人机会均等的观点。他们这样做就好像说所有的人类并不属于同一种群,好像某些人种在学习其他人种的经验和发明创造方面的能力不如别人。另外一些极端分子攻击宗教团体——犹太教或天主教——或否认个人信奉不可知论的权利。尽管这些明确表示不想要民主的极端分子的观点同宪法及传统的价值观念背道而驰,他们仍然能够得以陈述自己的观点,其原因就是崇尚民主的人们通常也是糊里糊涂的。

  • 第14题:

    There are two general approaches to attacking a (1)encryption scheme.The first attack is known as cryptanalysis.Cryptanalytic attacks rely on the nature of the algorithm plus perhaps some knowledge of the general characteristics of the ( ) or even some sample plaintext- ciphertext pairs. This type of ( ) exploits the characteristics of the algorithm to attempt to deduce a specific plaintext or to deduce the key being used. If the attack succeeds in deducing the key, the effect is catastrophic: All future and past messages encrypted with that key are compromised. The second method, known as the ( )-force attack, is to try every possible key on a piece of ( ) until an intelligible translation into plaintext is obtained. On average, half of all possible keys must be tried to achieve success.
