of school was very interesting and couldn39。 t be easily fotten. I went to my science class in the morning and found a seat in the back. I waited there for 15 minutes before the bell rang. The science teacher told us about some class rules. No one talked to me and I didn39。 t talk to anyone else. I was one of those very shy girls. After the science class, I had an English class. I thought it would be boring but later I found it very funny. When the classes of the morning ended I went to lunch. I sat outside the dining room with no one to talk to and no food because I was too nervous to join the lunch line. I kept looking around hoping to see someone I knew but I never saw anyone. Lunch ended and I went to have my art class. I was the first one there and not even my teacher was there yet. So I sat at my desk and started drawing some pictures. I didn39。 t notice the rest of the class walking in or the girl that was standing behind me till I was surprised by the voice, So what are you drawing? It was a girl who had really long hair. She ended up being my best friend and one of the kindest and liveliest girls I know. In the next class meeting, the teacher asked us to talk about the past holiday. I was glad to make some new friends in the class. The first day of high school was hard for me but I got through it. 61. What do we know about the writer39。 s science class? A.

C If you39。 re ever apart from your children, a new study says just talking on the phone will help just as much as a hug(拥抱 ). If you39。 re a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother39。 s voice alone can be just as forting to an anxious child as physical contact(接触 ). In an experiment, researchers from the University of Wisconsin Madison asked a group of girls between the ages of 7 and 12 to solve math problems in front of judges—a stressful situation for anyone. Before the girls were set to give their answers, the researchers measured their levels of two hormones(荷尔蒙 ): cortisol, which goes up during stressful periods, and oxytocin, the love hormone, which goes down at the same time. After the girls finished the problems, some of them got to meet up with their mothers right away. The moms came in and hugged the girls. Another group of the girls didn39。 t see their mothers, but received phone calls from them, in which their mothers told them how well they39。 d done. The final group had no contact with their mothers, but instead watched an animal movie, March of the Penguins. Finally, the girls39。 hormone levels were measured again. Although the movie was interesting, it did nothing to reduce the children39。 s anxiety—but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on reducing the girls39。 stress levels. So, no matter how old you are, if you39。 re feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better. 66. If a girl is under stress, .

The girls39。 levels of hormones we。
