Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them,“Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered,“Your brother. Because electricity travaels faster than sound waves.”“That’s every good,”Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said.“Yes, Kate.”
“I disagree,”Kate said.“Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.” Miss Gogers was teaching her class_________.

Fear may be felt in the heart as well as in the head，according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies，compared with the point when the heartbeat is relaxed.Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event，depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said：“Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces.Dr Garfinkel said，“The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus our hearts can also affect what we see and what we don’t see－and guide whether we see fear.”
To further understand this relationship，the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person’s feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’to each other to change our feelings and reduce fear，”Dr Garfinkel said.
“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced，we may be able to develop more successful treatments for anxiety disorders，and also for those who may be suffering from serious stress disorder.”What is the finding of the study?
| A．One’s heart affects how he feels fear. |
| B．Fear is a result of one’s relaxed heartbeat. |
| C．Fear has something to do with one’s health. |
| D．One’s fast heartbeats are likely to cause fear. |
The study was carried out by analyzing________.
| A．volunteers’ heartbeats when they saw terrible pictures |
| B．the time volunteers saw fearful pictures and their health conditions |
| C．volunteers’ reactions to horrible pictures and data from their brain scans |
| D．different pictures shown to volunteers and their heartbrain communication |
Which of the following is closest in meaning to“mechanism” in Paragraph 6?
| A．Order. | B．System. |
| C．Machine. | D．Treatment. |
This study may contribute to________.
| A．treating anxiety and stress better |
| B．explaining the cycle of fear and anxiety |
| C．finding the key to the heartbrain communication |
| D．understanding different fears in our hearts and heads |
On a sunny day last August，Tim heard some shouting.Looking out to the sea carefully，he saw a couple of kids in a rowboat were being pulled out to sea.
Two 12yearold boys，Christian and Jack，rowed out a boat to search for a football.Once they’d rowed beyond the calm waters，a beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for it and the boat was out of control.
Tim knew it would soon be swallowed by the waves.
“Everything went quiet in my head，”Tim recalls(回忆)．“I was trying to figure out how to swim to the boys in a straight line.”
Tim took off his clothes and jumped into the water.Every 500 yards or so，he raised his head to judge his progress.“At one point，I considered turning back，” he says.“I wondered if I was putting my life at risk.”After 30 minutes of struggling，he was close enough to yell to the boys，“Take down the umbrella！”
Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowing，but the waves were almost too strong for him.
“Let’s aim for the pier(码头)，”Jack said.Tim turned the boat toward it.Soon afterward，waves crashed over the boat，and it began to sink.“Can you guys swim？”he cried.“A little bit，”the boys said.
Once they were in the water，Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys’faces.
“Are we almost there？”they asked again and again.“Yes，”Tim told them each time.
After 30 minutes，they reached the pier.Why did the two boys go to the sea?

Mothers and daughters go through so much－yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother，Sheila Solomon Klass，both gifted professional writers，prove to be ideal cowriters as they examine their decades of motherhood，daughterhood，and the wonderful ways their lives have overlapped (重叠)．
Perri notes with amazement how closely her own life has mirrored her mother’s：both have fulltime careers；both have published books，articles，and stories；each has three children；they both love to read.They also love to travel－in fact，they often take trips together.But in truth，the harder they look at their lives，the more they acknowledge their big differences in circumstance and basic nature.
A child of the Depression (大萧条)，Sheila was raised in Brooklyn by parents who considered education a luxury for girls.Starting with her college education，she has fought for everything she’s ever accomplished.Perri，on the other hand，grew up privileged in the New Jersey suburbs of the 1960s and 1970s.For Sheila，wasting time or money is a crime，and luxury is unthinkable while Perri enjoys the occasional small luxury，but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.
Each writing in her own unmistakable voice，Perri and Sheila take turns exploring the joys and pains，the love and bitterness，the minor troubles and lasting respect that have always bonded them together.Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork.Perri admits that she can’t sort out all the mess in the households，even though she knows it drives her mother crazy.Together they compare thoughts on bringing up children and working，admit longhidden sorrows，and enjoy precious memories.
Looking deep into the lives they have lived separately and together，Perri and Sheila tell their motherdaughter story with honesty，humor，enthusiasm，and admiration for each other.A written account in two voices，Every Mother Is a Daughter is a duet (二重奏) that produces a deep，strong sound with the experiences that all mothers and daughters will recognize.Why does Perri think that her own life has mirrored her mother’s?
| A．They both have gone through difficult times. |
| B．They have strong emotional ties with each other. |
| C．They have the same joys and pains，and love and bitterness. |

While Jennifer was at home taking an online exam for her business law class，a monitor(监控器)a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment，the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room.Her Internet access was locked－remotely－to prevent Internet searches，and her typing style was analyzed to make sure she was who she said she was：Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating，this is the cutting_edge and a key to encourage honesty in the booming field of online education.The technology gives trust to the entire system，to the institution and to online education in general.Only with solid measures against cheating，experts say，can Internet universities show that their exams and diplomas are valid—that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade，the concern over cheating has become sharper in the last year with the growth of“open online courses.”Private colleges，public universities and corporations are jumping into the online education field.spending millions of dollars to attract potential students，while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras，a number of other hightech methods are becoming increasingly popular.Among them are programs that check students’ identities using personal information，such as the telephone numbers they once used.
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones.As in many university classes，term papers are scanned against some large Internet data banks for cheating.Why was Jennifer watched in an online exam?
| A．To correct her typing mistakes. |
| B．To find her secrets in the room. |
| C．To prevent her from slowing down. |
| D．To keep her from dishonest behaviors. |
