Yawning sends out certain messages---either “Oh, this movie is boring”or I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is so overheated?
A new study, led by a research team of Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.
The research team did an experiment on 160 people , 80 in summer and 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
【小題1】The purpose of the experiment is ________.
| A．to prove people yawn in winter and in summer equally. |
| B．to indicate brain can regulate temperature naturally |
| C．to find the frequency of people’s yawning |
| D．to show the real reason why people yawn |
| A．longer outdoor summertime results in more yawns. |
| B．yawning frequency changes with outdoor time |
| C．yawning frequency increases with outdoor time |
| D．longer outdoor wintertime leads to fewer yawns |
| A．when the air temperature is lower outside the body |
| B．when the hot air breathed in makes the brain hotter |
| C．when the air temperature is higher than the body |
| D．when the air temperature is equal to the body. |
| A．Yawning is a Sign of Brain Disease |
| B．Yawning Carries Some Information |

| D．Yawning Cools Your Brain |

Eddie’s father used to say he’d spent so many years by the ocean, breathing seawater. Now, away from that ocean, in the hospital bed, his body began to look like a beached fish. His condition went from fair to stable and from stable to serious. Friends went from saying, “He’ll be home in a day,” to “He’ll be home in a week.” In his father’s absence, Eddie helped out at the pier (碼頭), working evenings after his taxi job.
When Eddie was a teenager, if he ever complained or seemed bored with the pier, his father would shout, “What? This isn’t good enough for you?” And later, when he’d suggested Eddie take a job there after high school, Eddie almost laughed, and his father again said, “What? This isn’t good enough for you?” And before Eddie went to war, when he’d talked of marrying Marguerite and becoming an engineer, his father said, “What? This isn’t good enough for you?”
And now, regardless of all that, here he was, at the pier, doing his father’s labor.
Parents rarely let go of their children, so children let go of them. They move on. They move away. It is not until much later, as the heart weakens, that children understand: their stories, and all their achievements, sit on top of the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives.
Finally, one night, at his mother’s urging, Eddie visited the hospital. He entered the room slowly. His father, who for years had refused to speak to Eddie, now lacked the strength to even try.
“Don’t sweat it, kid,” the other workers told him. “Your old man will pull through. He’s the toughest man we’ve ever seen.”
When the news came that his father had died, Eddie felt the emptiest kind of anger, the kind that circles in its cage.
In the weeks that followed, Eddie’s mother lived in a confused state. She spoke to her husband as if he were still there. She yelled at him to turn down the radio. She cooked enough food for two. One night, when Eddie offered to help with the dishes, she said, “Your father will put them away.” Eddie put a hand on her shoulder. “Ma,” he said, softly, “Dad’s gone.”“Gone where?”
【小題1】In Paragraph four, the writer wants to say that __________.
| A．Children wouldn’t have achieved so much without their parents’ support |
| B．Children often feel regretful because they leave their parents |
| C．Children like moving away from their parents |
| D．Children can never understand how much their parents have devoted to them |
| A．Don’t touch it | B．Don’t worry about it |
| C．Don’t let him down | D．Don’t give it up |
| A．dbca | B．dcab | C．bcda | D．bacd |
| A．Eddie’s mother liked to listen to the radio |
| B．Eddie and his wife lived in his mother’s apartment |
| C．Eddie’s mother missed her husband so much that she was at a loss |
| D．Eddie often helped his mother wash the dishes |

Zhang Li is studying at Cambridge, UK. She has bought a bicycle and is worried about security. Her friend, Kate, found this article and sent it to her.
Introduction
A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps.
Basic Security
Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lampposts(燈柱) or trees. Take off smaller parts and take them with you, for example lights and saddles(車座).
Locks
Get a good lock. There are many different types in the shop. Buy one that has been tested against attack. Ask for advice from a bike shop.
Marking
Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a simple way to identify your bicycle.
Registration
There are a number of companies who will security mark your bicycle for you. They will then put your registration number and personal details on their computer database(數(shù)據(jù)庫). Then if your bicycle is found it will be easy to get in touch with you.
Finally
Keep a record of the bicycle yourself: its make, model and registration number. You can even take a photograph of it. This will prove the bicycle belongs to you.
【小題1】Which part of the article gives you information on how to lock up your bicycle when you leave it?

Roger Alvarez, 22, was one of the 52 percent of students who didn’t make it through his senior year at Manual Arts High School in Los Angeles.
He dropped out several years ago, but by the time he was in ninth grade, Alvarez says he already knew he wasn’t going to graduate.
“There’s a certain amount of knowledge you have to have when you enter in a specific grade, and I didn’t have it.” Alvarez says,“Every class I used to go in, I was like, ‘Do I know this? I don’t know this.’”
It was a shameful attitude, he tells his former English teacher, Antero Garcia, 29.
“You were determined to help me, but what was I willing to give? I could have actually tried.”
For his part, Garcia wants to know how he could have reached out to Alvarez better, but Alvarez says Garcia had always been helpful.
“I mean, you could cheer me up, and then I see other students doing way better,” Alvarez says,“So then, I get nervous. I get stuck, and then my motivation goes to the floor.” He felt the situation was hopeless.
“You talked to me like if I could do it, but inside me, I knew I couldn’t.” he tells Garcia,“I just didn’t want you to think that I’m…stupid.”
Now, school is a life tool that Alvarez says he’s missing—but his teacher isn’t to blame.
“Always, I just wanted you to know…you were a good teacher, and I always respected you.” he tells Garcia,“Some teachers, I felt like they only wanted to teach a certain group of people. But you looked at me and you paid attention.”
“Maybe it didn’t get me to graduate, but there’re a lot of teachers, they don’t take the time to take a look. And it was never your fault.”
Alvarez now works the night shift at a loading dock(碼頭). He still hopes to get his degree one day.
【小題1】When Alvarez entered a grade, he was sure that ___________.
| A．he wasn’t going to pass the class |
| B．he would do better than other students |
| C．he might learn an amount of knowledge |
| D．he would try his best to learn at class |
| A．he hid his goal from others | B．he lost heart gradually |
| C．he built up his motivation | D．he fell to the ground completely |
| A．paid no attention to teaching | B．had no time to read books |
| C．didn’t care about what he did | D．showed no respect to students |
| A．a(chǎn) dropout complains about being treated badly |

It’s hard not to feel cheated and over-charged when you receive unexpected roaming (漫游) charges while traveling abroad—whether they come from making phone calls or checking e-mails.
Jeff Gardner received an $ 11,000 bill from Verizon after spending four days in Jamaica. Before the trip, Mr. Gardner, who runs a fly-fishing business in Grayling, Michigan, said he called Verizon to find out what it would cost to use his cellphone for calls and his wireless card to check e-mails while in Jamaica. He said he was told that calls would be about $ 2 a minute and that there would be no extra charges for data as he was on an unlimited plan. The latter part turned out to be wrong.
“I don’t mind paying a fair amount for fair service, but $11,000 for four days is ridiculous,” said Mr. Gardner, who used his phone carefully and economically on the trip. He also tried to check and send e-mails using his wireless card, but quickly gave up after the e-mails didn’t go through. Still, his Verizon bill said more than 500,000 kilobytes (千字節(jié)) of data was delivered while he was in Jamaica, an amount Mr. Gardner said is 100 times what he normally uses in a month.
As travelers increasingly use smart phones abroad in the same way they do at home—to check e-mails, update Facebook and Twitter and pull up online maps—many are facing costly roaming fees, which providers charge when customers use their phones outside their service area. In fact, roaming charges have gotten so out of hand that the Federal Communications Commission has proposed a plan that would require wireless companies to send their customers a voice or text message when they are approaching their plan’s limit, when they have reached that limit and when they are starting to result in roaming fees.
【小題1】Why did Jeff Gardner call Verizon before his trip to Jamaica?
| A．To hand over his business. |
| B．To check his cellphone bill |
| C．To find out information about Jamaica. |
| D．To find out information about roaming charges. |
| A．Extra charges were made for Jeff Gardner’s data delivery. |
| B．Jeff Gardner’s calls were charged over $2 per minute. |
| C．Jeff Gardner’s plan turned out to be limited. |
| D．Jeff Gardner had difficulty delivering data abroad. |
| A．was careless with phone use |
| B．delivered no more data than at home |
| C．received quite poor e-mail services |
| D．frequently used his wireless card to send e-mails |
| A．Make customers know when they’re outside their service area. |
| B．Get customers informed when they’re near the limit of their plan. |
| C．Stop serving customers when they’ve reached their plan’s limit. |
| D．Limit some services to reduce the amount of roaming charges abroad. |

Our particular parenting style reflects our own way of “l(fā)ooking”. Here’s a great piece of writing reflecting parent’s particular ways on the parenting style that have become known humorously as helicopter parenting and submarine parenting.
Helicopter parents hover over their children, managing every aspect of their child’s life. On the contrary, submarine parents remain “hidden” coming to the surface when guidance is needed.
While helicopter parents may have the best intentions, in reality, they are raising children with few problem solving skills. Children with hovering parents never get the chance to face disappointment and build up their ability to recover from misfortune.
Think about your typical submarine. Submarines usually remain underwater. In case of a need for emergency surfacing, submarines can rise so quickly. They are driven partially out of the water. Submarine parents also remain out of sight, yet able to appear in the case of an emergency.
I admit I’m a submarine mom. My job as a parent is to have fun with my daughters while letting them explore and learn natural consequences. 
My older daughter found herself acting in commercials and making more than minimum wage as a teen. To give her a sense of the real world, I insisted she spend three weeks every summer, picking strawberries and earning $3.50 on a good day.
When my youngest daughter Sondra was six, she wanted a very expensive American Girl Doll. I cut the full color 18" picture out of the American Girl catalogue and had it laminated (壓膜). “Here’s your American Girl Doll.” I said “When you turn nine, I’ll buy you the 3D doll on your birthday.” Sondra played with her flat doll for months, making clothes and furniture for her. She learned creativity. I saved $88.00.
【小題1】What is the text mainly about?
| A．Various means of transportation. |
| B．Funny experiences of a mom. |
| C．Humorous stories about parents. |
| D．Different styles of parenting. |
| A．leave behind | B．fly around | C．watch over | D．set aside |
| A．They give their children proper guidance. |
| B．They try to do everything for their children. |
| C．They teach their children how to face failures. |
| D．They help their children explore by themselves. |

What’s in name? Well, apparently, our general happiness. Psychologists say that what we are called has a direct connection with our happiness.
Those called Judy and Joshua are the happiest, while Lynn or Ben is likely to be the unhappiest, according to research. Psychologist Dr David Holmes found that this can cause the association(聯(lián)想) that others make with the name. Hearing the name Judy may make them think of actress Judi Dench or TV presenter Judy Finnigan, and people who are considered good-natured and happy. On the other hand, people think Paulines are unhappy because of the character Pauline Fowler from the TV programme East Enders. The research claims that this association influences the person with the name and so their personality is shaped to fit in. Dr David Holmes said, “This also has some relation with the original meaning of the name, for example, the original meaning of Judy is ‘praised’.”
Certain names also work well in certain aspects of life. In the workplace Richard and Judy are the happiest, while those called Ruth and Carly are the happiest in relationships. At the other end of the scale the unhappiest workers are Stuart and Liz, with the unhappiest in relationships being Frank and Harriet.
Dr Holmes said, “The relation we have with certain names, particularly important namesakes (同名者), also shapes how we see ourselves and so may have an effect on our confidence. Names are like product brands in having a powerful effect on attitudes and should therefore be chosen with care.”
“Other names are connected with being brave, outgoing or serious. Therefore, many celebrities change their names to ones which reflect these characteristic. This, in turn, influences parents when they choose names for their babies,” said Dr Holmes, “while names connected with ordinary people are rarely chosen for their babies.”
【小題1】What’s the main idea of this passage?
| A．How to choose a good name for babies. |
| B．The relation between names and happiness. |
| C．How to have a name connected with celebrities. |
| D．The relation between names and success. |
| A．Joshua and Ben. | B．Pauline and Frank. |
| C．Richard and Stuart. | D．Ruth and Joshua. |
| A．names and product brands |
| B．famous people’s names |
| C．names and personality |
| D．parents’ choices of baby names |
| A．Personality and self-confidence. | B．Self-confidence and position. |
