[解析]
(1)A细节理解题.根据第二段第一句Childhood is a time when there are few responsibilities to make life difficult可知童年的时候是很少有责任的还有后面几句的大概意思是如果孩子有很好的父母,他就会受到很好的照顾.故选A.
(2)A推理判断题.文章讲到世界对小孩子来说是新鲜有趣的,对老人来说是熟悉的,未含有人们容易满足的这一意思,故选A.
(3)A词义猜测题.根据后面几句Childhood is a time when there are few responsibilities to make life difficult.If a child has good parents,he is fed,looked after and loved,whatever he may do.意思是如果孩子有很好的父母,他就会受到很好的照顾,可以推断出此处句意:童年的时候是很少有责任的,故选A,duty名词,责任.
(4)D主旨大意题.根据文章主题段第一段Each age has its pleasures and its pains,and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.说明他认为如果一个人能充分利用好自己每一个年龄的时间,他就是快乐的.故D正确.
