1．I have been consistenly opposed to feeding a baby regularly．As a doctor，mother and scientist in child development I believe there is nothing to recommend it，from the baby's point of view．
Mothers，doctors and nurse alike have no idea of where a baby's blood sugar level lies．All we know is that a low level is harmful to brain development and makes a baby easily annoyed．In this state，the baby is difficult to calm down and sleep is impossible．The baby asks for attention by crying and searching for food with its mouth．
It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied．The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night．I've never heard anything so ridiculous．Baby feeding shouldn't follow a timetable set by the mum．What is important is feeding a baby In the best way，though it may cause some ineonvenience in the first few weeks．
Well，at last we havecopper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding．The research finds out that babies who are fed on demand do better at school at age 5，7，11and 14，than babies fed according to the clock．By the age of 8，their IQ （智商）scores are four to five percent higher than babies fed by a rigid timetable．This
Research comes from Oxford and Essex University using a sample （样本）of 10，419children born in the early 1990s，taking account of parental education，family income，a child's sex and age，the mother's health and feeling style．These results don't surprise me．Feeling according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels．
I hope this research will put an end to advocating strictly timed baby feeling practices．

分析 本文是典型的议论文，论点：是"反对定期喂养婴儿"；论据：1．我们不知道婴儿的血糖的情况2．定期喂养的危害 3．实验表明，按需喂养较定期喂养的孩子更聪明；结论：希望结束定期喂养的习惯，按婴儿需要喂养．
解答 31．D 细节理解题． 根据文章第二段"The baby asks for attention by crying and searching for food with its mouth．"可知，孩子哭，是因为低血糖引发的，而低血糖实际上就是没有吃饱，所以孩子哭的话，就是为了得到食物．这也和文章整体的意思相一致．
32．C 推理判断题．由第三段第三句"I've never heard anything so ridiculous （ 荒谬可笑的）"以及本文最后一句"I hope this research will put an end to advocating strictly timed baby feeling practices．"可知，Dr King认为严格定时喂养孩子是错误的，故选C．
33．B 词义猜测题．由第四段的具体描述可知，按需喂养的孩子比定时喂养的孩子智商要高，学习表现更好，因此这个研究是实践中被论证和证明的，是可信赖的，因此B项符合，故选B．
34．D 细节理解题．由第四段第三句"By the age of 8，their IQ（智商）scores are four to five percent higher than babies fed by a rigid timetable"可知，按需喂养的孩子智商高，IQ 高和 wiser 属于同义重现．因此D项符合，故选D．
35．C 细节理解题．由本文的第一句"I have been consistently opposed to feedinga baby regularly"就提出观点，"反对定期喂婴儿"，最后一句"I hope this research will put an end toadvocating strictly timed baby feeding practices"希望结束主张严格按时喂养的习惯．既然"不定期"，也就是按婴儿需要喂养，故选C．另外，也可以根据"The research finds out that babies who arefed on demand do better at school at age 5，7，11 and 14，than babies fedaccording to the clock．By the age of 8，their IQ （智商）scores are four to five percent higher than babies fed by arigid timetable．"句中的on demand和wheneverit wants food 是同义重现．
点评 解答细节理解题时，一个常用的方法就是运用定位法，即根据题干和选项中的关键词从原文中找到相关的句子，与选项进行比较从而确定答案；推理判断题既要求学生透过文章表面文字信息推测文章隐含意思，又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断，力求从作者的角度去考虑，不要固守自己的看法或观点．
