Approximately 90% of people in the world are naturally right-handed. Why is this so, and are we born one way or the other? The answer to this question is rather complicated.
In babies and young children, no single side becomes dominant until around the age of eight. At 12 weeks, babies usually use both hands equally, but by 16 weeks, they mostly use the left hand for touching.[21]By 24 weeks, they have changed again and start using both hands. Then at 28 weeks, they become one-handed again, although this time it is the right hand that is used more. At 32 weeks, they start using both hands again. Whan they reach the age of 36 weeks, there is another change, with most babies now preferring to use the left hand. Between 40 and 44 weeks, the right hand is once again more used. At 48 weeks, babies switch to using their left hands again, and then between 52 and 56 weeks, the right hand takes over.
There are further changes still. At 80 weeks, the right hand loses control, and both are used again equally. When the young child reaches the age of two, the right hand takes over again, but between two and a half and three years, both hands are used equally. Things finally become stable at around four years and stay the same until, by the age of eight, one hand is strongly dominant over the other.
19. Which hand do babies use most of touching when they are at 16 weeks?
20. Until how old will a child’s one hand be strongly dominant over the other?
21. What do we learn about babies’ using their hands?
选项
A、The younger they are, the less they use both of their hands.
B、They become one-handed and start using both hands alternately.
C、One of their hands develops more skillfully as they age.
D、Most children in the world are bom right-handed.
答案
B
解析
选项都是概括性的陈述,可以猜测本题需要综合全文的大意来解答。原文用很长的一段话来叙述婴儿几周大的时候用双手,几周大的时候更常用单手(左手或者右手),可知婴儿在8岁以前是交替使用单、双手的,故B正确。
