Most teens need more than 9 hours of sleep each night. But about 1 in 4 teens has trouble in sleeping. Lack of sleep can affect everything from our feelings to how well we focus on tasks like studying. It can also influence sports performance,increase our chances of getting sick,and may lead to weight gain in some people.

  How can we get the sleep we need? Here are some ideas:

  Be active during the day. Get at least 60 minutes of exercise a day. Physical activity can decrease stress and help people feel more relaxed. Just don't work too close to bedtime because exercise can wake you up before it slows you down.

  Say goodnight to electronics. Experts suggest using the bedroom for sleep only. At least shut everything down an hour or more before lights out.

  Keep a sleep routine. Going to bed at the same time every night helps the body expect sleep. Creating a set bedtime routine can improve this relaxation effect. Reading,listening to music,spending time with a pet,writing a diary or doing anything else can relax you.

  Expect a good night's sleep. Instead of worrying that you won't sleep,remind yourself that you can. Say "Tonight,I will sleep well" several times during the day.  It can also help to practice breathing exercises or gentle exercises before bed.

  Everyone has a sleepless night once in a while. But if you regularly have trouble in sleeping and you think it's affecting your mood or performance,talk to your doctor.

2. B細(xì)節(jié)理解題。由題目中的關(guān)鍵tips about better sleep ,可回原文定位并理解全文。根據(jù)Be active during the day. Say goodnight to electronics. Keep a sleep routine.和Expect a good night's sleep.可知，文章共涉及四條關(guān)于更好睡眠的建議。

3. A推理判斷題。由題目中的關(guān)鍵詞trouble in sleeping and it affects his performance,可回原文定位于最后一段第二句。根據(jù)"But if you regularly have trouble in sleeping and you think it's affecting your mood or performance,talk to your doctor."可以判斷，如果戴維有嚴(yán)重的睡眠問題，影響到他的表現(xiàn)，他應(yīng)該去看醫(yī)生。

5. D主旨大意題。文章主要介紹了獲得更好睡眠的一些建議。

  "What is success?" Mr. Gruber asked his 6th grade business class. It was his opening question for the first class of the term.

  "Success is riding in a sweet car,watching an 80-inch TV,and living in a place with at least twelve rooms," one student answered,earning laughs from all the students.

  Mr. Gruber smiled,but shook his head, "Tom,that is excess (過量的) .That is not success." 

  "How about being able to support your family?" a blonde girl named Sandy in the front suggested as an answer.

  "Now we're getting closer,but try thinking about what you need and what you want."   "Getting everything you want," Tom shouted out an answer again,trying for more laughs. 

  Mr. Gruber sighed, "I believe we've already talked about excess versus (與...相比) success."

  "Getting everything you need,but some of what you want," James,sitting in the back,said aloud.

  "Quite right ！" Mr. Gruber clapped. "Success is getting everything you need and some of what you want. The more you get what you want,the more successful you are. You do reach a point where you are living in excess,though."

  "Does this have anything to do with business?" Tom asked. It seemed if the answer wasn't funny,he wouldn't be happy.

  "Well,think about it in this way: The point of business is to make a living to support your family. Once you have properly seen to (確保) their needs,you can then see to getting the extras that you want." 

  "What if I don't have a family?" he continued to be difficult. 

  "Then you have to provide for yourself,a family of one."

  "He has goldfish to think about!" Peter,Tom's friend? shouted out.

  "Then he needs to provide a family of one with a fishbowl," Mr. Gruber corrected himself. Tom nodded,satisfied with that answer.

  "So in the next nine weeks,we're going to study basic business situations,like having a checking account and understanding credit cards."

  Tom rubbed his hands together excitedly and said, "When do we get to start spending?" 

  "You already are,Tom. You're spending time with us！”Mr. Gruber laughed. "Now,let's see what you guys know about credit cards ..."

  All around the world,people drink tea. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea.

  In China,for example,tea is always served when people are getting together. The Chinese drink it any time of the day,at homes or in teahouses. They prefer their tea plain,with nothing else in it.

  Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony (儀式) .It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in the Japanese homes.

  Another teadrinking country is England. In England,the late afternoon is "teatime". Almost everyone has a cup of tea then. The English usually make tea in a teapot and drink it with milk and sugar. They also eat cakes,cookies (甜餅) and little sandwiches at teatime. This is so called "Afternoon Tea" in Britain.

  In the United States people drink tea mostly for breakfast or after meals. Americans usually use tea bags to make their tea. Tea bags are faster and easier than making tea in teapots. In summer,many Americans drink cold tea―"iced tea". Sometimes they drink iced tea from cans (罐) ，like soda(蘇打水) .
