研究顯示：子女少的家庭對孩子成長更有利

　　Every kid from a small family has probably felt sorryfor themselves at one time or another for not havingloads of brother and sisters. From the outsidelooking in, there's a lot to envy about families thathave enough kids to field their own baseball game,produce complex harmonies a la "The Sound ofMusic," or put on a play without casting stuffedanimals in major roles.

　　每一個來自小家庭的孩子大概都或多或少覺得遺憾，由於他們沒有一大堆兄弟姐妹陪同發展。從外面上看，假如一個家庭中有充足多的孩子來打屬於他們本身家庭的棒球，大概是在《音樂之聲》中演唱龐雜的和聲，再大概是在一場家庭劇中不應用動物來充任重要腳色，這其實是很使人愛慕的一件事。

　　But a new study shows there are convincing reasons not to romanticize large families. Thestudy suggests that with every additional kid born, the other siblings are more likely to sufferfrom lower cognitive abilities and more behavioral issues, and have worse outcomes later in life.

　　但一項新研討表現，咱們有使人佩服的來由證實，不該美化多後代家庭。該研討發明，每增長一個孩子，其他孩子認知才能下降的大概性就更高，他們會湧現更多行動題目，將來生存的終局也會更糟。

　　The researchers found that the birth of another kid also lowered the overall amount ofeducation that each child received.

　　研討職員發明，多生一個孩子還會下降每一個孩子受教導的水平。

　　Countries like Norway, which have extensive welfare programs, parental leave and othersupportive policies for families, and strong public education, might see less of a trade-off forfamilies between the quantity and quality of children, they hypothesize. But parents incountries like the United States and China, might be forced to choose, they say.

　　他們以為，在像挪威如許具有完美的社會福利系統、怙恃有充足的休假、具有其他的家庭攙扶政策，和壯大的大眾教導的國度中，每一個家庭不太會去衡量孩子的數目和質量這一題目。然則那些生存在像美國和中國如許國度的怙恃，必需要在二者當中做出選取。
