问题     A set of genes play a role in learning to read and do math, but this ability is not just gene-driven,【C1】________schooling and help from parents are also vital【C2】________.
    Early mathematical ability and literacy are known to【C3】________in some families, but the genes【C4】________affect this have until now been【C5】________unknown.
    Scientists looked into a data pool called the Twins Early Development Study, which【C6】________12-year-olds from nearly 2,800 British families.
    The team compared twins and【C7】________children to see how they【C8】________in tests for maths and reading comprehension, and then matched the children’s genomes.
    Between 10 percent and half of the genes in-volved in reading were also involved in math, they found, and tiny variants in these【C9】________genes influence skill level.
    【C10】________it’s also clear how important our life experience is in making us better at one or the other. It’s this complex【C11】________of nature and nurture as we grow up【C12】________shapes who we are.
    Professor Robert Plomin said the study was the first to estimate the【C13】________from DNA alone on learning ability.
    But, he stressed, the genetic valiants that were identified were not【C14】________"literacy or numeracy" genes.
    【C15】________they formed part of a more complex mechanism in which many genes each【C16】________a small, but combined, effect on learning ability.
    "Children differ【C17】________in how easy or difficult they find learning, and we need to recognize and【C18】________these individual differences," said Plomin.
    "Heritability does not【C19】________that anything is set in stone—it just means it may take more effort from parents, schools and teachers to【C20】________the child up to speed."  
【C18】
选项 A、restore
B、restrain
C、reserve
D、respect
答案D
解析 空格填入的词与recognize“认识”并列，因此该词应与recognize在词语色彩上是一致的，即同为褒义性描述，故选择D项respect“尊重”，表示“尊重个体差异”。个体差异是客观存在的，不需要“恢复”，也不能“人为保留”，据此排除A项restore“恢复”和C项reserve“保留”。B项restrain“限制”为贬义描述，与recognize“认识”的词语色彩完全相反。
