It is not unusual to see your desk-mate yawn (打呵欠) as he complains that he didn't have a good sleep the night before. Many teens don't get enough sleep because they have too much homework, which keeps them up at night. Some teens cannot sleep at night even when they want to.
Studies show that during your teenage years, the body's biological clock is reset, telling you to sleep later at night and wake up later in the morning.
But changes in the body clock aren't the only reason teens lose sleep. Lots of people have insomnia (失眠). The most common cause of insomnia is stress. But all sorts of things can lead to insomnia. These include physical discomfort, emotional troubles and even sleeping environment. It's common for everyone to have insomnia from time to time. But if it lasts for a month or more go and see a doctor.
Some people have a condition that causes stomach acid (酸) to move backward towards the chest. This produces the uncomfortable, burning feeling called heartburn. So even if the person doesn't notice the feelings of heartburn because he is sleeping, he may feel tired the next day.
Most teens have nightmares sometimes. But, if they are frequent, a person's sleep pattern can be seriously affected. The most common cause of nightmares is emotional problems, such as stress (压力) or anxiety. If you have them a lot, it's a good idea to talk to a doctor.
Doctors encourage teens to make lifestyle changes to develop good sleeping habits. You probably know that coffee can keep you awake, but did you know that playing video games or watching TV does the same?
【小题1】The main idea of the first paragraph is ________.
| A．There is a problem that teenagers can’t get enough sleep. |

新活力总动员暑系列答案科目：高中英语 来源： 题型：阅读理解
It seems hard to watch someone yawn（打哈欠） and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force.
Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don’t develop this deeply rooted behavior until around age four, the study found. Kids with autism (自闭症) are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect.
"Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did.
"The fact that autistic kids don’t do it might mean they’re really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others’," she added. "Autistic people never seem to understand that."
Like infectious （有感染力的）laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group.
【小题1】What does the new study suggest, according to the first two paragraphs?
| A．Yawning is a form of communication. |
| B．It is easy to stop yawning when you see others yawn. |
| C．Children follow others in yawning just after they are born. |
| D．Yawning has some mysterious force which is related to God. |
| A．humans differ from animals because they communicate with others |
| B．yawning is a kind of emotional connection among humans |
| C．emotions are infectious, but yawning is not |
| D．yawning helps clear ears on planes |
| A．It is natural to yawn back if people around you yawn. |
| B．Some kids are too young to yawn after others. |
| C．Yawning can be used to test children’s development. |
| D．Kids with autism yawn easily when others yawn. |
| A．yawning is different from infectious laughter and crying in theory |
| B．it is bad manners to yawn on some social occasions |
| C．the more you yawn, the happier you will be |
| D．yawning can make people feel relaxed |

Although similar in appearance to hyenas(土狼), African wild dogs are nevertheless true wild canine(犬). They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas.
They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy（统团） exists within the group, but the animals are friendly to one another. The young and the infirm（体弱的） are given special privileges within the group.
African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu.
Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution（迫害） have also had a negative impact on African wild dog populations. This species is also susceptible to a variety of diseases such as distemper, which is controlled in domestic .dogs. Conservation of the African wild dog's natural habitat must have the highest priority, as these dogs suffer in habitats modified by human intrusion（干扰）．

A report brought back by most visitors to the US is how friendly, polite, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet American’s friendliness and helpfulness is an observation made so frequently that it deserves comment.
For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of distraction, and brought news of the outside world．
The tough realities of the border also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest settler agent. It was not a matter of choice for the traveler or only a charitable impulse (冲动） on the part of the settlers. It reflected the hardship of daily life: if you didn't take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation．
Today there are many charitable organizations which specialize in helping the exhausted traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist routes. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner, amazing." Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be understood neither as superficial（表面的）nor as artificial（虚伪的）, but as the result of a historically developed cultural tradition.
As is true of any developed society, in America a complex set of cultural signals and customs is the basis of all social inter-relationships. And, of course, speaking a language does not necessarily mean that someone understands social and cultural patterns. Visitors who fail to "translate" cultural meanings properly often draw wrong conclusions. For example when an American uses the word "friend", the cultural meanings of the word may be quite different from those it has in the visitor's language and culture. It takes more than a brief encounter on a bus to tell polite customs from individual interest. Yet, being friendly is a virtue （美德） that many Americans value highly and expect from both neighbors and strangers.
【小题1】In the eyes of visitors from the outside world, ________．
| A．rude taxi drivers are hardly seen in the US |
| B．small-minded officials deserve a serious comment |
| C．Canadians are not so friendly as their neighbors |
| D．most Americans are ready to offer help |
| A．culture has an influence over social inter-relationship |
| B．polite customs and individual interest are inter-related |
| C．various virtues shows themselves only among friends |
| D．social inter-relationships equal the complex set of cultural customs |
| A．to improve their hard life | B．in view of their long-distance travel |
| C．to add some taste to their own daily life | D．out of a charitable impulse |
| A．tends to be superficial and artificial |
| B．is generally well kept up in the United States |
| C．is always understood properly |
| D．has something to do with the busy tourist route |

London has always been known for its "black fogs". In the winter of 1952, a milky white fog rolled into the city. As the smoke poured into the air, it was so hard to see that people had to walk in front of the buses to guide them. In this way, the most serious air pollution disaster in history began. When it was over, more than 4,000 people had been killed by the thick black smog.
New York City has had several London-type smogs since 1950. Each time, 100 to 400 deaths were caused by the smog. Although these smogs were not as deadly as London's, New York City has the worst air pollution problem in the United States.
In all the killer smogs, factories and homes poured smoke and fumes into the air from the furnaces. The chemical fumes combined with the water droplets in the fog to form harmful substances. These substances caused the illness of those who breathed the polluted air.
Usually, such harmful fumes rise into the upper air and are blown away by the wind. But sometimes there is an unusual weather condition called a temperature inversion. A layer of cold air remains near the ground as smoke and fumes pour into it. This is covered by an upper layer of warm air that acts like a lid. It prevents the polluted cooler air from rising. The harmful fumes pile up and make people ill. The smog may be so thick that airports are closed and chains of collisions occur on the highways.
Another type of smog occurs in Los Angeles. Here the weather may be clear and sunny. But stinging eyes and dry coughs show that harmful chemicals fill the air. The smog is due to invisible gases, mostly from automobile exhaust. Because these chemicals are changed by the sun high up in the air, it is called photochemical smog. It contains automobile exhaust fumes and nitrogen oxides changed by the sun's rays. Added to these are sulfur dioxide and other fumes from factories and oil refineries. Photochemical smog is found in many large cities all over the world.
Killer smogs don't happen very often, fortunately. But in Beijing, a combination of automobile exhaust fumes, home furnace smoke, and factory waste gases pours into the air. This may also happen in the suburbs, or out in the country, where large factories have been built. A number of harmful substances have been found in the air there. When these substances are breathed in day after day, the health of the population is affected.
【小题1】Why do people call this phenomenon "black fog"?
| A．It is black and dirty. |
| B．It can affect the health. |
| C．It can kill people. |
| D．It is too thick for people to see something. |
| A．Water. | B．Wind. | C．The sun. | D．Cold air. |
| A．many people will be killed |
| B．black smoke may pour into the air |
| C．the weather may be fine |
| D．people have to walk to work |
| A．London | B．New York | C．Los Angeles | D．Beijing |

A woman renewing her driver’s license at the County Clerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.
“What I mean is,” explained the recorder, “do you have a job, or are you just a …”
“Of course I have a job,” said Emily. “I’m a mother.”
“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.
One day I found myself in the same situation. The clerk was obviously a career woman, confident and possessed of a high sounding title. “What is your occupation?” she asked.
The words simply popped out. “I’m a Research Associate in the field of Child Development and Human Relations.”
The clerk paused, ballpoint pen frozen in midair.
I repeated the title slowly, and then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.
“Might I ask,” said the clerk with new interest, “Just what you do in this field?”
Coolly, without any trace of panic（恐慌，惊慌） in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t）, in the lab and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”
There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.
As I drove into our driveway, buoyed up (依托) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7 and 3.
Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern.
I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”
Motherhood…What a glorious career! Especially when there’s a title on the door.
【小题1】What can we infer from the conversation between the woman and the recorder at the beginning of the passage?
| A．The woman felt ashamed to admit what her job was. |
| B．The recorder was impatient and rude. |
| C．The author was upset about the situation that mothers faced. |
| D．Motherhood was not recognized and respected as a job by society. |
| A．curious | B．puzzled | C．indifferent | D．interested |
| A．calm | B．panic-stricken | C．confident | D．cool |
| A．Because the author cared little about rewards. |
| B．Because she admired the author’s research work in the lab. |
| C．Because she thought the author did admirable work. |
| D．Because the writer did something she had little knowledge of. |
| A．To show how you describe your job affects your feelings toward it. |
| B．To argue that motherhood is a worthy career and deserves respect. |
| C．To show that the author had a grander job than Emily. |
| D．To show that being a mother is hard and boring work. |

Busy as I am every day, I always open my computer and check my email. Most of the time I am simply doing finger exercises, another form of piano practice without beautiful tones. Sometimes, however, I receive a gift, reminding me of the gifts in my life. The following passage is one of those gifts.
Peter Jones is a 92-year-old, short, calm and proud man. Every morning he is fully dressed by eight o’clock, with his hair fashionably combed and face perfectly shaved even though hi is unable to see anything. He would move to a nursing home today. His wife of 70 years old has recently passed away, making the move necessary.
After hours of waiting patiently in the entrance hall of the nursing home, he smiled sweetly when told his room was ready. As he moved his walking stick skillfully to the elevator, the nurse provided a visual description of his tiny room. “I love it,” he stated with enthusiasm. “Mr. Jones, you haven’t been the room,” said the nurse.
“That doesn’t have anything to do with it,” he replied. “Happiness is something you decide on ahead of time. Whether I like my room or not doesn’t depend on how the furniture is arranged…it’s how I arrange my mind. I have already decided to love it. It’s a decision I make every morning when I wake up. I have a choice: I can spend the day in bed complaining of the difficulty I have with the parts of my body that no longer work, or get out of bed and be thankful for the ones that do.”
Each day is a gift, and as long as we are alive. We’ll focus on the new day and all the happy memories we’ve stored just as Mr. Jones does.
【小题1】What do we know about Mr. Jones ?
| A．He is a blind but very neat. |
| B．His wife died many years ago. |
| C．He likes playing the piano. |
| D．His room in the nursing home is big. |
| A．worried | B．curious | C．disappointed | D．content |
| A．the furniture | B．the room | C．a decision | D．a gift |
| A．Each Day is a Gift | B．Be Always Grateful |
| C．Living in a nursing room | D．Arrange Your Mind Every Day |

Part-time jobs for 15 and 16 years olds
| Waiter / Waitress A job as a waiter or waitress is a good choice for 16-year-olds. Not only can one earn $9-$12 an hour, but they can also get the tips (小费). Most people that visit a restaurant don’t just have good food. They come here to relax and have a good time. Besides serving food quickly, a young waiter who talks to them politely with a smile on his face will make the diners enjoy their time at the restaurant. |
| Work in a library If one is fond of books, working in a library is another suitable choice. Besides the pay is good, it offers a lot of free time when students can actually sit down and finish their homework. So on returning home, they would have time to hang around with friends or just relax. So working in a library is an excellent part-time job for teens, especially for school students. |
| Internet jobs There are many ways of making money through online jobs like clicking on advertisements, visiting sites and signing up with them. However, such online jobs don’t pay well. A better Internet job for teens is to complete online surveys. These are quite simple surveys that usually ask one about his/ her opinions and ideas.
