Today sheworks for a large software company. Now twenty-seven, Rachel takes classes twice a week afterwork. She is learning to use the computer program PowerPoint. “I enjoyed college, but my job doesn’t use information I learned when I was doing my degree,” Rachel says , “This course is helping me to do my job better. In the future, I might go back to school and got an MBA.”In the past, when students graduated from college and got a job, they usually stopped studying. Today, lifelong learning is becoming more common. In the United States, people can return to school in their late twenties, thirties, or older to get a higher degree, such as a master’s or PH.D. Like Rachel many more are taking training courses to improve their workplace skills.With many classes now available through the Internet, it is easier for people to get degrees or training by distance learning.Mayumi Hosoya, who is forty teaches Japanese at a community college in New York. “Next term, I’ll be teaching some of my classes using the internet. This is new for me.” says Mayumi. “At the moment, I am taking a course to learn how to teach this way.” At the same time, Mayumi’s seventy-year-old mother and father are taking a distance learning course in Art History. “We love the subject.” says Mayumi’ father, “and now we can study with people from all over the world. I never thought learning could be this much fun.”61.The reading is mainly about _________.A.

One of the children was Jessica McClure. She was18 months old. Jessica’s mother, who worked at the day care center, waswatching the children. Suddenly Jessica fell and disappeared. Jessica’s mother cried and ran to her.A well was in the yard of the canter. The well was only eight inches across, and a rock always covered it. But children had moved the rock. When Jessica fell, she fell right into the well. Jessica’s mother reached inside the well, but she couldn’t feel Jessica. She ran to the phone and dialed 911 for help.Man from the fire department arrived. They discovered that Jessica was about 20feet down in the well. For the next hours, the men talked and planned Jessica’s rescue 营救 . Then they told Jessica’s parents their plan.“We can’t go into the well,” they said “It’s too narrow. So, we’re going to drill(钻)a hole next to the well. Then we’ll drill a tunnel across to Jessica. Then we’ll bring her up through our hole.”The men began to drill the hole on a Wednesday morning. “We’ll reach Jessica in a few hours,” they though. The men were wrong. They had to drill through solid rock. Two days later, on Friday morning, there were still drilling. And Jessica McClure was still in the well.During her days in the well, Jessica sometimes caller her mother. Sometimes she slept, sometimes she cried, and sometimes she sang.All over the world people waited for news of Jessica. They read about her in newspapers and watched her rescue on TV. Everyone worried about the little girl in the well.At 8 P.M on Friday, the men finally reached Jessica and brought her up from the well. Jessica was dirty, hungry, thirsty, and tired. Her foot and forehead was badly injured. But Jessica was alive.A doctor at the hospital said, “Jessica is lucky she is very young. She ‘s not going to remember this very well.”Maybe Jessica will not remember her days in the well. But her parents, her rescuers, and many other people around the world will not forget them. After Jessica’s rescue, one of the rescuers made a metal cover for the well. On the cover he wrote, “To Jessica, with love from all of us.”66. Jessica fell into the well because__________.A. her mother was not watching herB. she was too weakC. the rock cover was moved awayD. other children played with her67.
