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 text helps us to know more about teenagers" ______.

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. Why did Jan Jennings ask the lawyer to repeat what he said

Text 4We feel it is important to start reading to your child right from the start—the younger the better! With little ones (children from birth to 4) it is very important to read and reread books. Starting early makes the job of the listener (for you will be teaching your child how to listen) easier, as it helps to develop an early love of the written and spoken word. We believe that you should read aloud to your child at least once every day. Set a special reading time during the day or evening when you can settle down and enjoy a book, without interruption. For most families, reading aloud at bedtime is a common practice. We understand that it can be quite discouraging to read to a child who takes no interest. Take heart! Learning to listen takes experience. The more you read, the more your child will learn to sit for a story. Children have a natural development of responses(反应) to your reading. By the time your child reaches 6-7 months, s/he is attracted by the book in your hand, and would like to test it out by using it as a chew(咀嚼) toy. This is natural! By one year, your child is learning to listen and talk about the pages, often shouting out things s/he recognizes. Encourage this! And at the onset(起始) of walking, you have your biggest challenge yet. Your child is always on the go. You need to set your reading time for a time in the day when your child is preparing to settle down. This means bedtime. Remember, it is your right and duty to teach your child about the power of books. Of course, it doesn"t happen overnight, but the returns are great! Parents may find it most difficult to read to their child when s/he ______.
