　　Passage Two
　　Questions 26 to 30 are based on the following passage:
　　From the moment that an animal is born it has to make decisions. It has to decide which of
　　the things around it are for eating, and which are to be avoided when to attack and when to run
　　away. The animal is, in effect, playing a complicated and potentially very dangerous game with
　　its environment, discomfort or destruction.
　　This is a difficult and unpleasant business and few animals would survive if they had to
　　start from the beginning and learn about the world wholly by trial and error, for there are the
　　have possible decisions which would prove fatal. So we find, in practice, that the game is always
　　arranged in favour of the young animal in one way or another. Either the animal is protected
　　during the early stages of its learning about the world around it, or the knowledge of which way
　　to respond is built into its nervous system from the start.
　　The fact that animals behave sensibly can be attributed partly to what we might call
　　genetic(遗传的) learning, to distinguish it from the individual learning that an animal does in the
　　course of its own life time. Genetic learning is learning by a species as a whole, and it is achieved
　　by selection of those members of each generation that happen to behave in the right way. How-
　　ever, genetic learning depends upon a prediction that the future will more or less exactly resemble
　　the past. The more variable individual experience is likely to be, the less efficient is genetic
　　learning as a means of getting over the problems of the survival game. It is not surprising to find
　　that very few species indeed depend wholly upon genetic learning. In the great majority of animals, behaviour is a compound of individual experience and genetic learning to behave in particular
　　ways.
　　26. According to the first paragraph, the survival game is considered potentially very dangerous
　　because
　　A) animals are constantly threatened by attacks
　　B) wrong decisions will lead to the disappearance of a species
　　C) decisions made by an animal may turn out to be fatal
　　D) few animals can survive in their struggle with the environment
　　27. It is implied but not directly stated in the passage that most animals
　　A) are likely to make wrong decisions
　　B) have made correct decisions for their survival
　　C) depend entirely on their parents in learning about the world around them
　　D) survive by means of individual learning
　　28. Genetic learning is effective only if
　　A) the survival game is arranged in favour of the young animals
　　B) the animals can adapt themselves to the changing surroundings
　　C) circumstances remain more or less the same
　　D) the animals have varied individual experiences
　　29. The best TITLE for this passage would be
　　A) The Decision - Making Ability of Animals
　　B) Survival and Environment
　　C) Reward and Penalty for Animals
　　D) Behaviour and Survival
　　30. How is genetic leaning achieved?
　　A) It is inherited from animals with keen observation.
　　B) It is passed down from those animals that behave in the correct way.
　　C) It is taught to the young generation.
　　D) It is learned by the new generation through trial and error. 　　Passage Three
　　Questions 31 to 35 are based on the following passage:
　　Scientists, like other human beings, have their hopes and fears, their passions and disap-
　　pointments    and their strong emotions may sometimes interrupt the course of clear thinking
　　and sound practice. But science is also self - correcting. The most fundamental principles and
　　conclusions may be challenged. The steps in a reasoned argument must be set out for all to see.
　　Experiments must be capable of being carried out by other scientists. The history of science is
　　full of cases where previously accepted theories have been entirely overthrown, to be replaced by
　　new ideas which more adequately explain the data.
　　While there is an understandable inertia - usually lasting about one generation - such
　　revolution in scientific thought are widely accepted as a necessary and desirable element of scientific progress. Indeed, the reasoned criticism of a prevailing belief is a service to the supporters of that belief; if they are incapable of defending it, they are well - advised to abandon it. This self -questioning and error- correcting aspect of the scientific method is its most striking property and sets it off from many other areas of human endeavor, such as religion and fine arts.
　　The idea of science as a method rather than as a body of knowledge is not widely appreciated outside of science, or indeed in some corridors inside of science. Vigorous criticism is constructive in science more than in some other areas of human endeavor because in it there are adequate standards of validity which can be agreed upon by competent scientists the world over.
　　The objective of such criticism is not to suppress but rather to encourage the advance of new
　　Ideas:those which survive a firm skeptical(怀疑的) examination have a fighting chance of being
　　right, or at least useful. 　　32. It can be learned from the context that the word "inertia" (Para. 2, Line 1) most probably
　　means
　　A) strong resolution                   B) unwillingness to change
　　C) a period of time                    D) prevailing belief
　　33. The "revolution in scientific thought" (Para. 2, Lind 2) refers to
　　A) acceptance of the reasoned criticisms of prevailing scientific theories
　　B) the continuous overthrow of existing scientific theories
