科普学问类
阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
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 ridicul
ous. 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 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, 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.

阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
As the railroads and the highways shaped the American West in the past centuries, a new electrical generating (发电) and transmission (输送) system for the 21st century will leave a lasting mark on the West, for better or worse. Much of the real significance of railroads and highways is not in their direct physical effect on the scenery, but in the ways that they affect the surrounding community. The same is true of big solar plants and the power lines that will be laid down to move electricity around.
The 19th century saw land grants (政府拨地) offered to railroad companies to build the transcontinental railroads, leaving public land in between privately owned land. In much of t
he west, some of the railroad sections were developed while others remained undeveloped, and in both cases the landownership has presented unique challenges to land management. With the completion of the interstate highway system, many of the small towns which sprang up as railway stops and developed well, have lost their lifeblood and died.
