Are you carrying too much on your back at school? Back experts in the U. S.A. were worried that young students are having back and neck problems because they are carrying too much in their schoolbags.
"It hurts my back when I run," said Ebelin Reyes, a student in Virginia. "It"s hard to go upstairs with my schoolbag because it"s too heavy."
Students have to carry heavy schoolbags on their backs for a whole week"s study. Ebelin is one of them. They have schoolbags with two straps (带子) to carry them, but a number of students with heavy loads (负荷) have switched to rolling schoolbags. The schoolbags have wheels (轮子) and can roll on the ground. Shirley Park"s schoolbag weighs (重) 10 kilos, and she said, "I"ll change to a rolling schoolbag because I am starting to have back pain."
How much is too much? Experts say that students should carry no more than 10 to 15 % of their own body weight. A few students have had a good idea to lighten the load: less homework.

The year was 1839. Vice (副……) President Richard M. Johnson was in New York City on his way to Philadelphia. He was expected at a meeting at 6:30 that evening. When did he begin his trip? At noon! In 1839, it took six and one-half hours by train and ferry (渡船) to get from New York City to Philadelphia. That wasn"t so bad. In 1817, the trip took three days!
If this were a cold winter day, Vice President Johnson would have started much earlier. The Delaware River might freeze over. There would
be no ferry and he would have to walk across the ice.
Today, it"s possible to leave New York City on the 9:00 a.m. train and be in Philadelphia at 10:29 a.m. In fact, some people live in New York City and work in Philadelphia. They use the train schedule (时刻表) below.
How do you read the train schedule? Suppose you" re in New York City and you want to go to Princeton. Run your finger down the list of cities to find Princeton. Next, move your finger to the right. You will see the times that trains arrive in Princeton. Then run your finger up to the times listed across from New York. That"s when the trains leave New York. Make your choice and enjoy the ride!
