问题     Poor people have I.Q.’s significantly lower than those of rich people, and the awkward conventional wisdom has been that this is in large part a【C1】______of genetics. After all, a series of studies seemed to indicate that I.Q. is largely inherited. Identical twins raised apart, for example, have I.Q.’s that are remarkably【C2】______.
    If intelligence were deeply connected with our genes, that would lead to the depressing conclusion that, neither schooling nor antipoverty programs can【C3】______much. Yet while this view of I.Q. has been widely held, new evidence shows that it is【C4】______wrong. Richard Nisbett, a professor of psychology at the University of Michigan, has just proved it completely wrong in a new book, Intelligence and How to Get It.
    Professor Nisbett strongly advocates intensive early childhood education because of its proven ability to【C5】______I.Q. The Milwaukee Project, for example, took African-American children considered at risk for mental retardation(迟钝)and assigned them【C6】______either to a control group that received no help or to a group that enjoyed intensive day care and education from 6 months of age until first grade. By age 5, the children in the program【C7】______an I.Q. of 110, compared with 83 for children in the control group. Another proven【C8】______is to tell junior-high-school students that I.Q. is expandable, and that their intelligence is something they can help shape. Students exposed to that idea work【C9】______and get better grades.
    The implication of this new research on intelligence is that if we were to【C10】______early childhood education and support schooling, we might be able to raise America’s collective I.Q. significantly.
A)previously B)intervention C)harder D)similar
E)raise F)factor G)averaged H)interfere
I)randomly J)profoundly K)push L)analyzed
M)function N)diligent O)accomplish
【C2】
选项
答案D
解析 此处需填入动词的过去分词或形容词。上文都是在讲智商在很大程度上是遗传的，则此处的例子应该是说同卵双胞胎即使是分开抚养，智商也非常“相似”，similar符合文意。
