5 东海原甲藻(简称甲藻)是我国东海引发赤潮的藻种之一，研究甲藻光合作用的生理特性可为认识赤潮发生机理提供重要信息。　　某研究小组探究pH对甲藻光合作用的影响，设计了以下实验：将生长旺盛的甲藻等量分成5组培养，各组藻液pH分别设定为6.0、7.0、8.0、9.0、10.0，在黑暗中放置12h，然后在适宜光照等相同条件下培养，随即多次测定各组氧气释放量并计算净光合速率。将实验结果绘制成下图。 (1)本实验除了通过测定氧气释放量，还可以通过测定_______吸收量来计算净光合速率。 (2)黑暗放置过程中，藻液pH会有所变化，因此在测定氧气释放量前，需多次将各组pH分别调到______，这是控制实验的_________变量。 (3)若甲藻长时间处于pH10.0条件下，甲藻_____(能、不能)正常生长繁殖，请据图分析并说明原因：_________________________。 (4)实验表明，甲藻光合作用适宜pH6.0～9.0。但海水在该pH条件下，一般不会发生赤潮，原因是发生赤潮除了与pH、温度、光照强度等因素有关外，最主要还与海水的_________有关。 (5)研究小组进一步探究了温度对甲藻光合作用的影响。根据实验结果得出：甲藻生长繁殖的适宜温度为15℃-30℃，最适温度为25℃左右，当温度为9℃和33℃时，甲藻不能正常生长繁殖。请根据这些信息在下图中画出净光合速率随温度变化的示意曲线。
6 （B） 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/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． 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 as the basis of their behavior． 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． 69．Which of the following statements would the supporters of the “nature” theory agree with? A．A person’s instincts have little effect on his actions． B．Environment is important in determining a person’s behavior and personality． C．Biological reasons have a strong influence on how we act． D．The behaviorists’ view correctly explains how we act． 70．Concerning the nature/nurture controversy, the writer of this article____________． A．supports the nature theory B．supports the nurture theory C．believes both are completely wrong D．thinks that the correct explanation of human behavior will take ideas from both theories． 71．In the United States, Black people often score below White people on intelligence tests．With this in mind, which of the following statements is NOT true? A．Nature proponents would say that Whites are genetically superior to Blacks． B．Supporters of the nature theory would say that Whites score well because they have a superior environment． C．Behaviorists would say that Blacks often lack the educational and environmental advantages that Whites enjoy． D．Nurture proponents would disagree that Blacks are biologically inferior to Whites．
