Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance her time so that she will feel comfortable taking time out from studying to spend time with friends or rest.Show a positive attitude. 75 Your panic, anxiety and blame contribute to your teen‘s pressure.

I wasn't 36 watching for you.‖ We were very polite, this stranger and I. Then we went 37 our way after saying goodbye.But at 38 , a different story is told. How we treat our loved ones, young and old. Later in the kitchen, as I 39 our meal, my daughter walked up to me, very still. When I turned, I 40 knocked her down. ―Get out of the way!‖ I shouted with a frown(皱眉). She stepped away silently, with her little heart 41 . I didn't realize how harshly(苛刻地) I had spoken.That night, when I lay 42 in bed, God's quiet voice spoke to me and said, ―While43 with a stranger, you are calm and polite, but with those you love, you are QUICK to excite... Go look around on the kitchen floor, you'll find some flowers there by the 44 . Those are the flowers she brought for you. She 45 them herself-- pink, yellow, and your favorite blue. She stood there quietly, and you never saw the 46 in her eyes.‖By this time, I felt sad and small and now my own tears had begun to fall. I quietly went and knelt by her 47 : ―Wake up, my dear,‖ I said, ―Are these the flowers you picked up for me?‖ She smiled, ―I found them out by the tree. I 48 them in a napkin（餐巾）, just for you. I knew you'd like them, especially the 49 .‖ I said, ―I am so sorry that I missed them today... And I 50 have fussed（慌乱）at you that way.‖And she whispered, ―Mommy, that's okay... I still love you 51 .‖ I hugged her and said, ―I love you, too and I LOVE the flowers.‖Do you know that: if you die tomorrow, the 52 you are working for could easily replace you in a matter of （大约）days. But the family you leave _53 will feel the loss for the rest of their lives.

FRIEND第二节阅读理解AThe most frightening words in the English language are, ―Our computer is down.‖ You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, ―I‘m sorry, I can‘t sell you a ticket. Our computer is down.‖―If your computer is down, just write me out a ticket.‖―I can‘t write you out a ticket. The computer is the only one allowed to do so.‖I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, ―What do all you people do?‖ ―We give the computer the information about your trip, and then it tells us whether you can fly with us or not.‖―So when it goes down, you go down with it.‖―That‘s good, sir.‖―How long will the computer be down?‖ I wanted to know.―I have no idea. Sometimes it‘s down for 10 minutes, sometimes for two hours. There‘s no way we can find out without asking the computer, and since it‘s down it won‘t answer us.‖After the girl told me they had no backup(备用) computer, I said. ―Let‘s forget the computer. What about your planes? They‘re still flying, aren‘t they?‖―I couldn‘t tell without asking the computer.‖―Maybe I could just go to the gate and ask the pilot if he‘s flying to Washington, ‖ I suggested.―I wouldn‘t know what gate to send you to. Even if the pilot was going to Washington, he couldn‘t take you if you didn‘t have a ticket.‖―Is there any other airline flying to Washington within the next few hours?‖―I wouldn‘t know, ‖ she said, pointing at the dark screen. ―Only ‗IT‘ knows. ‗It‘ can‘t tell me.‖By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.1. The best title for the article is _______.A. When the Computer Is DownB. The Most Frightening WordsC. The Computer of the AirportD. Asking the Computer2. What could the girl in the ticket office do for the passengers without asking the computer?A. She could sell a ticket.B. She could write out a ticket.C. She could answer the passengers‘ questions.D. She could do nothing.3. Why do you think they had not a backup computer?A. Because it was easy downB. Because it was very expensive.C. Because it was not advanced enough.D. Because it was not as big as the main computer.4. The last paragraph suggests that _______.A. a modern computer won‘t be down.B. computers can take the place of humansC. sometimes a computer may bring suffering to peopleD. there will be great changes in computersBDo dogs understand us?Be careful what you say around your dog. It might understand more than you think.A border collie(长毛牧羊犬) named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues(线索), the scientists believe Rico must understand the meanings of certain words.In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.Rico is thought to be smarter than the average(普通的) dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!1. From paragraph 2 we know that __ .A. animals are as clever as human beingsB. dogs are smarter than parrots and chimpanzeesC. chimpanzees have very good word-learning skillsD. dogs have similar 'learning abilities as 3-year-old children2. Both experiments show that .A. Rico is smart enough to get all commands rightB. Rico can recognize different things including toysC. Rico has developed the ability of learning mathematicsD. Rico won't forget the names of objects once recognizing them3. Which of the following statements is true?A. The purpose of the experiments is to show the border collie's mental abilities.B. Rico has a better memory partly because of its proper early training.C. The border collie is world-famous for recognizing objects.D. Rico is born to understand its owner's commands.4. What does the writer want to tell us?A. To train your dog.B. To talk to your dog.C. To be friendly to your dog.D. To be careful with your dog.C（选作）Everyone has got two personalities—the one that is shown to the world and the other that is secret and real.

You‘re shy and you don‘t normall y like meeting people. You prefer to be on your own. You‘re easily hurt.If you sleep on your side，you have usually got a well-balanced personality. You know your strengths and weaknesses. You‘re usually careful. You have a confident personality. You sometimes feel anxious，but you don‘t often get depressed.
