11．__________ the experiment right，I tried again and succeeded．（　�。�
A．Not having doneB．Having not doneC．Not doingD．Not done

分析 因為沒有正確地做這個實驗，于是我再試了一次，結(jié)果成功了．

解答 答案：A 根據(jù)句意，沒有正確做實驗這個動作是發(fā)生在我再試一次之前，且是再試一次的原因，所以非謂語動詞要用現(xiàn)在分詞的完成式having done，又非謂語動詞的否定形式是直接在其前面加否定詞not，所以空白處要用Not having done，Not having done the experiment righ在句中做原因狀語，故選A．

點(diǎn)評 本題考查否定句和現(xiàn)在分詞的完成式．考生在解題時要理清動作之間的先后關(guān)系，并掌握非謂語動詞的否定形式中not的位置，就可以選出答案．

6．People have wondered for a long time how their personalities and behaviors are formed．It is not easy to explain why one person is intelligent and another is not，or why one is cooperative and another is competitive．
Social scientists are，of course，extremely interested in these types of questions．They want to explain why we possess certain characteristics and exhibit certain behaviors．There are no clear answers yet，but two distinct schools of thought on the matter have developed．As one might expect，the two approaches are very different from one another，and there is a great deal of debate between proponents of each theory．The controversy is often referred to as"nature and nurture"．
Those who support the"nature"side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors．That our environment has little，if anything，to do with our abilities，characteristics，and behavior is central to this theory．Taken to an extreme，this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts（本能）．
Proponents of the"nurture"theory，or，as they are often called，behaviorists，claimed that our environment is more important than our biologically based instincts in determining how we will act．A behaviorist，B．F．Skinner，sees humans as beings whose behavior is almost completely shaped by their surroundings．The behaviorists'view of the human being is quite mechanistic； they maintain that，like machines，humans'respond to environmental stimuli（刺激） as the basis of their behavior．
Socially and politically，the consequences of these two theories are far-reaching．In the US，for example，blacks often score below whites on standardized intelligence tests．This leads some"anature"proponents to conclude that blacks are genetically lower in status than whites．Behaviorists，on the contrary，say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy，and that，as a result，they do not develop the same responses that whites do．
Either of these theories cannot yet fully explain human behavior．In fact，it is quite likely that the key to our behavior lies somewhere between these two extremes．That the controversy will continue for a long time is certain．
67．This passage is mainly concerned withD．
A．relation between personality and behavior
B．relation between behavior and environment
C．different accounts of patterns of human behavior
D．different theories of the formation of human behavior
68．The underlined word"proponents''in paragraph 2 meansC．
A．creators         B．a(chǎn)dvisors         C．a(chǎn)dvocates        D．judges
69．In paragraph 5，the author mainly writes aboutA．
A．the considerable influence of the two theories
B．differences between the blacks and whites
C．racial discrimination in the United States
D．different responds to intelligence tests
70．What's the author's purpose in writing the passage？D
A．To call our attention to the changes of human behavior．
B．To urge scientists to do more research in social science．
C．To give us a detailed explanation of human behavior．
D．To present an argument in the field of social science．
