根据以下材料，回答下列问题。
I have been consistently 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 nurses 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 inconvenience in the first few weeks.
Well, at last we have copper-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 5,7,11 and 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 10,419 children born in the early 1990s, taking account of parental education, family income, a child ´s sex and age, the mother´s health and feeding style. These results don´t surprise me. Feeding 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 feeding practices.
What does the author think about Dr King?
推断题。根据第三段中的"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."可知作者反对严格按时喂养婴儿，认为Dr King的观点 是荒谬的。故选C。
The word "copper-bottomed" in Paragraph 4 is closest in meaning to ________.
词义题。basic“基本的”，reliable“可靠的”，surprising“令人吃惊的”，interesting“有趣的”。根据第四段的实验结果的具体描述可知这项研究是可靠 的。故选B。
What does the research tell us about feeding a baby on demand?
细节题。根据第四段中的“The research finds out that babies who are fed on demand do better at school at age 5,7,11 and 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.”可知，按需喂养的婴儿到8岁的时候比按时喂 养的婴儿更聪明。故选D。
The author supports feeding the baby________
主旨题。通读全文可知本文就如何喂养婴儿涉及了两种观点：按时喂养和按需喂养。作者在文章的第一句“I have been consistently opposed to feeding a 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 to advocating strictly timed baby feeding practices.”再 次表示希望结束严格按时喂养的习惯；第四段论述了按需喂养的好处，也就是什么时候需要就喂孩子，故选C。
