问题 单项选择题

读下左图,判断下列说法正确的是()

A、图中四个点的气压关系为①<②<③<④

B、甲地多晴朗天气

C、甲地温度高于乙地

D、气流由甲地流向乙地

答案

参考答案:C

解析:

气压分布的基本规律:等压面上气压相等;垂直方向上,越往高空气压越低;故图示四地的气压高低为①>②=④>③,A错误;甲地的高空气压较乙地高空高,故判断甲地近地面气压较乙地低,B错误;甲地近地面的气压较乙地低,故判断甲地盛行上升气流,则甲地的气温较乙地高,C正确。近地面的气流由乙地流向甲地,D错误。

【点评】本题解题的关键掌握等压面附近的气压高低的判断方法:垂直方向上的气压分布基本规律,并能结合气压分布画图热力环流图示。

Starting with his review of Skinner’s Verbal Behavior, Noam Chomsky had led the psycholinguists who argue that man has developed an innate (天生的) capacity for dealing with the linguistic universals common to all languages. Experience and learning then provide only information about the (1) instances of those universal aspects of language which are needed to communicate with other people within a particular language (2) .

This linguistic approach (3) the view that language is built upon learned associations between words. What is learned is not strings of words per se (本身), but (4) rules that enable a speaker to (5) an infinite variety of novel sentences. (6) single words are learned as concepts: they do not stand in a one-to-one (7) with the particular thing signified, but (8) all members of a general class.

This view of the innate aspect of language learning is at first not readily (9) into existing psychological frameworks and (10) a challenge that has stimulated much thought and new research directions. Chomsky argues that a precondition for language development is the existence of certain principles "intrinsic (原有的) to the mind" that provide invariant structures (11) perceiving, learning and thinking. Language (12) all of these processes; thus its study (13) our theories of knowledge in general.

Basic to this model of language is the notion that a child’s learning of language is a kind of theory (14) . It’s thought to be accomplished (15) explicit instruction, (16) of intelligence level, at an early age when he is not capable of other complex (17) or motor achievements, and with relatively little reliable data to go on. (18) , the child constructs a theory of an ideal language which has broad (19) power. Chomsky argues that all children could not develop the same basic theory (20) it not for the innate existence of properties of mental organization which limit the possible properties of languages.
