今天的题目：
Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.
1. The reason some children are backward in speaking is most probably that ________.
they are incapable of learning language rapidly
they are exposed to too much language at once
their mothers respond inadequately to their attempts to speak
their mothers are not intelligent enough to help them
题目的解析：
1. Today no such severe lack exists as that ordered by Frederick.
参考译文：今天不存在像Frederick所要求的那种（照顾）的严重缺失。
2.Nevertheless, some children are still backward in speaking.
参考译文：但是有些孩子在说话方面依然落后。
3.Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly.
参考译文：原因常常就是，婴儿的大脑本来学语言很快，但母亲对于婴儿发出的信号并不敏感。（这个调序是不是很机智！）
4.If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again.
参考译文：如果这些敏感期被忽略了，那么获得（语言）技能的理想时期就错过了，这些（孩子）可能就再也不能容易地学习这些技能了。
5. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.
参考译文：小鸟在恰当的时间能很快地学会唱歌和飞行，但是一旦这个关键时期错过了这个过程就会变得非常缓慢。
The reason some children are backward in speaking is most probably that ________.
一些孩子在说话方面比较慢，最有可能的原因是什么？
精确定位到第三句：3.Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly.
参考译文：原因常常就是，婴儿的大脑本来学语言很快，但母亲对于婴儿发出的信号并不敏感。（这个调序是不是很机智！）
尤其是：the mother is insensitive to the signals of the infant
= their mothers respond inadequately to their attempts to speak
他们的母亲对于他们说话的尝试没有做出充分的回应
完美的替换！所以正确答案是B！
A和B的主语一看就知道不对！
D选项的主语对了，但是和母亲的智力没有关系！就是看母亲是不是敏感，也就是有没有做出充分的回应！
they are incapable of learning language rapidly
他们不能很快的学习语言。
they are exposed to too much language at once
他们同时面对太多的语言
Be exposed to = be confronted with 面对 （绝对必考短语！）
their mothers respond inadequately to their attempts to speak
他们的母亲对于他们说话的尝试没有做出充分的回应
their mothers are not intelligent enough to help them
他们的母亲不够聪明没法帮他们。
