[不定项选择题]共用题干
IQ-gene
In the angry debate over how much of IQ comes from the genes that children inherit from par-ents and how much comes from experiences,one little fact gets overlooked:no one has identified any genes(other than those that cause retardation)that affect intelligence.So researchers led by Robert Plomin of London's Institute of Psychiatry decided to look for some.They figured that if you want to find a"smart gene,"you should look in smart kids.They therefore examined the DNA of students like those who are so bright that they take college entrance exams four years ear-ly-and still score at Princeton-caliber levels. The scientists found what they sought."We have,"says Plomin,"the first specific gene ever associated with general intelligence."
Plomin's colleagues drew blood from two groups of 51 children each,all 6 to 15 years old and living in six counties around Cleveland.In one group,the average IQ is 103.All the children are white .Isolating the blood cells,the researchers then examined each child's chromosome 6 .Of the
37 landmarks on chromosome 6 that the researchers looked for,one jumped out:a form of gene called IGF2R occurred in twice as many children in the high-IQ group as in the average group-32 percent versus 16 percent. The study,in the May issue of the journal Psychological Science, concludes that it is this form of the IGF2R gene that contributes to intelligence.
Some geneticists see major problems with the IQ-gene study.One is the possibility that Plomin's group fell for"chopsticks fallacy".Geneticists might think they've found a gene for chopsticks flexibility,but all they've really found is a gene more common in Asians than,say,Af-ricans.Similarly,Plomin's IQ gene might simply be one that is more common in groups that em-phasize academic achievement."What is the gene that they've found reflects ethnicity?"asks ge-neticist Andrew Feinberg of Johns Hopkins University."That alone might explain the link to intel-ligence,since IQ tests are known for being culturally sensitive and affected by a child's environ-ment."And Neil Risch of Standford University points out that if you look for 37 genes on a chro- mosome,as the researchers did,and find that one is more common in smarter kids,that might re- flect pure chance rather than a causal link between the gene and intelligence.Warns Feinberg:"I would take these findings with a whole box of salt."

A.how many children learn by experience
B.how much of IQ comes from genes
C.how many children inherit genes from parents
D.how much of IQ comes from intelligence

[单项选择]
Experts say children can begin learning a second language in preschool, and should begin be- fore the age of ten to take advantage of young children’s natural ability to acquire language. This advantage is lost by the time most children encounter a foreign language in the classroom, in middle school or high school.
Dr, Noble Goss, an assistant professor of Spanish’ and German at Harding University in Arkansas, says, as a father of bilingual (双语的) children (My wife is Mexican), I know that not only it is easy for children m learn one or more languages, but they have an amazing way of separating them out more successfully than you would think.
If a child hears two languages early, he accepts both equally. But if given a chance to speak both, can they be fluent in both
Not everyone agrees that early childhood is the only time to start a language, however. Reeves, the chairman and founder of the Center for Performance Assessment in Denver,
A. starting early isn't a good idea
B. starting early sounds reasonable
C. starting early makes one sensitive to language
D. starting early makes one acquire a language better
