A: For years some people have been saying that railways are dead. They say, “Trains are slow, and they lose money. Motorcars and planes have made them unnecessary.”

B:    1.   . I think in these days of expensive oil, railways have become highly competitive with motorcars and planes.

A: Right. If you want to carry people or goods from place to place, they are much cheaper than planes.

B:    2.   . A plane goes in a straight line, and so does a railway.

A: What is more, it takes you from the heart of a city into the heart of another.    3.   . Nor does it hold you up as a car does in heavy traffic.

B:    4.   . Modern railway lines give you a smooth, untroubled journey. We’ve just entered the age of super-fast trains, traveling at 160 miles an hour and more.

A：5.

A. So railways will have very bright future, I dare say.

       But I wonder about my Momma sometimes, and all the other Negro(blacks )mothers who got up at 6 a.m. to go to the white man’s house with sacks over their shoes because it was so wet and cold. I wonder how they made it .They worked very hard for the man, they made his breakfast and they scrubbed his floors and they took care of his babies. They didn’t have too much time for us.

I wonder about my Momma ,who walked out of a white woman’s clean house at midnight and came back to her own where the lights had been out for three months ,and the pipes were frozen and the wind came in through the holes in the wall. She’d have to make deals with the rats: leave some food out for them so the wouldn’t bite the doors or the babies. The roaches（蟑螂）？Oh ,they were just like part of the family!

I wonder how she felt telling those white kids she took care of to brush their teeth after they ate, to wash their hands after they finish bathroom. She could never tell her own kids because there wasn’t soap or water back home.

I wonder how my Momma felt when we came home from school with a list of vitamins and pills the school nurse said we had to have .Momma would cry all night , and then go out and spend most of the rent money for pills. A week later ,the white man would come for his eighteen dollars’ rent and Momma would beg him to wait until tomorrow . She had to lie to him that she had lost her wallet or the relief check was coming soon or the white people had some money for her. Tomorrow I’d be hiding in the closet because there was only supposed to be two kids in the flat ,and I could hear the rent man shout at my Momma and call her a cheat. And when he finally went away, Momma put the sacks on her shoes and went off to the rich white man’s house to dress the rich white kids so their mother could take them to a special baby doctor.

For most pregnant women, exercise is the last thing on their minds. After all, keeping slim while you’re expecting isn’t exactly the top priority— rather, it’s making sure your baby gets enough nutrients to grow. But in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life.

The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance（胰岛素抵抗），a condition eventually leading to diabetes（糖尿病）. Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal（胎儿）development. In pregnant women, this condition means nutrients get shunted to the growing baby.

The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulin. So the University of Auckland’s Dr. Paul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise(有氧运动) might have on their insulin sensitivity and, ultimately, on their babies’ birth weight. Researchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exercise. When the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothers. In both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights.

Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging result. Even more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb.
