Text 1 It"s a time when school, homework, active social lives and part-time jobs keep teenagers (青少年) busy from early in the morning until late at night. They are likely to try to make up for a lack of sleep by "sleeping in" on the weekends. Unfortunately, this causes irregular sleep and actually makes the problem worse. Most teenagers are not able to fall asleep until late at night. Since many teens aren"t sleepy until around 11 p.m., but need to be at school by 7:30 or 8:00 a.m., they cannot get enough sleep. During puberty(青春期), the biological clock in the brain naturally re-sets to a later time, and this causes teens to fall asleep later. Then, when it"s time to get up, a teen"s body clock is likely to still be producing the night-time hormones(荷尔蒙). This makes it hard for them to feel active and energetic in the morning. A growing body of research suggests that starting high school later improves attendance, achievements and grades. A few years ago in an important study, test scores on the SAT college entrance exams in Edina, Minnesota jumped more than 100 points on average, when the morning school bell rang an hour later. Unfortunately, most schools are not set up to start later and fail to satisfy teen"s sleep needs. The study in Minnesota shows that starting morning school one hour later helps to ______.

Text 2 Chicago"s Children"s Hospital is the lucky receiver of a surprise $18 million gift from Gladys Holm. She once was a secretary who never earned more than $15,000 a year and never married. She lived alone in a small flat in Chicago, and was a volunteer at the Children"s Hospital. She was called the "Teddy Bear Lady" because she brought toy animals to sick children on her regular visits. But Miss Holm, who died in 1996 at the age of 86, was also a long-time buyer of stocks (股票). Over the years, she saved money that rose up to $18 million, which she left to the Children"s Hospital. It was the largest single donation in the hospital"s 115-year history. The hospital president, Jan Jennings, was shocked when she heard the news. "When Miss Holm"s lawyer called to tell me how much that money was, I asked him to repeat it, since I was certain I had misheard." Why did Gladys Holm feel so strongly about the Children"s Hospital Jennings said the hospital first touched Miss Holm"s heart nearly 50 years ago, when doctors there saved the life of her friend"s daughter. She never forgot the happiness she felt all those years ago. Holm"s gift will be devoted to heart disease research. People at the hospital said they regretted that they couldn"t thank Miss Holm for the surprising gift. According to the text, Miss Holm built up her fortune by ______.
