The Lewisvillle, Texas, school teachers were aware that the hours they spent on preparing lessons were too often wasted on many students. So Forestwood High School, Texas, used the “flipped (翻转的) classroom” method of instruction. “We’ve completely done away with our lecture,” Derow said. And homework assignments “are all done in class,” Bradley said.
With the flipped concept, a student’s usual homework assignment is to watch pre-recorded lectures on their computers or smart phones.They walk into class ready to discuss the topic, collaborate(合作) with other students and work on assignments based on what they learned from the video. Free from lecturing, the teachers can use class time to look deeper into the subject and focus on difficult concept. As students change from a passive to an active role, they learn critical thinking skills, learn to collaborate and become independent learners.
Instead of doing homework assignments alone at home, students are now “working together, talking about it,” Bradley said. “If they don’t agree on an answer, they debate it and have to justify their answers. It’s a higher level of learning.”
Her students give the flipped classroom high marks.
Sarah Lee, 14, watches the 30-minute videos on a home computer. She likes the ability to rewind the tapes if she doesn"t understand a concept. She also likes being able to watch the lessons on her own schedule.
One of her classmates, Dawson Depperschmidt has the same idea and thinks the time she spends in the classroom is more productive. “It gives us more time to learn at school,” Dawson said. “You get more in-depth in class.

举一反三
Hair color comes from the pigment melanin(黑色素), which determines your individual shade. Hair without any melanin is pure white. The pigment is produced in cells called melanocytes, which inject pigment into the hair. At some point in everyone"s lifetime, these cells slow down and eventually stop producing color. Scientists have yet to identify the exact mechanism by which melanocyte cell death occurs.
A study of more than 4,000 women and men from 20 countries determined that about 75% of people between the ages of 45 and 65 have some gray hair. In general, people of European descent gray earliest followed by Asians and Africans. It"s interesting to note that a lucky 1 in 10 has no gray hair by retirement age. Beginning at age 30, your chances of having gray hair go up 10-20% per decade.
It may feel like you have more grays after a stressful event, but that"s probably because middle age is basically a series of anxiety-ridden events. Between working, raising kids, and caring for older parents, the "sandwich" years of 45-65 can be stressful, especially for women. They are also when we naturally start to look older.
At this point, there is still no silver bullet to keep away the grays.
小题1:What would be the best title for this passage?
A.Going gray. | B.Tips to make hair color last |
C.Why does hair turn gray? | D.Gray hair is in fashion. |
A.Scientists have found out how to prevent hair from turning gray. |
B.Europeans are more likely to gray than Asians and Africans. |
C.Gray hair means poor health or a sign of illness. |
D.Everyone will inevitably get gray hair by retirement age. |
A.Being physically weak. | B.Stress from different sides. |
C.Death of melanocyte cell. | D.Genetic factors. |
A.Make-up | B.Scientific research. | C.Chemical weapon. | D.Cure. |
Scientists have come up with some researches on what makes different types of people“tick”.
The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad.
Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions—it will also use a GPS tracking system to log where the call is made.
And they’ve already made some pretty major breakthroughs into really getting under the skin of us humans.
The results from the pilot scheme make interesting scientific reading. Among the key revelations (﹦facts) are that callers feel happier at home and sadder at work.
To break it down, scientifically, it shows 45 percent of all emotions produced at home are “happy”and 54 percent of emotions at work are “sad”.
Meanwhile, people show more “intense”(﹦nervous) emotions in the evening than they do in the morning.
Of course, this could just be because most people feel too tired in the morning to get overly “intense”. Eating breakfast and getting to work on time is usually enough of an achievement.
Anyway, the Emotion Sense technology has been developed by psychologists(心理学家) and computer scientists who say it uses speech recognition software and phone sensors(传感器) attached to standard smart phones to judge how callers’ emotions are changed by everyday factors.
The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral-—boredom or passivity(消极) would fit into this last category.
小题1:How many emotions can the sensors tell?
A.Two | B.Three | C.Four | D.Five |
A.Scientists have put something testing people’s emotions under humans’ skin. |
B.There were some breakthroughs in this technology in getting something from people’s skin. |
C.In this technology, people’s skin was broken through. |
D.There were improvements in testing people’s emotions. |
A.Because morning is the start of a new day. |
B.because they feel too tired in the morning. |
C.Because of humans’ physiological structure. |
D.Because of the fresh air and bright sunlight. |
A.Speech recognition software. | B.Phone sensors. |
C.GPS sensors. | D.Translation system. |
Researchers at the University of California have carried out the study and found that embarrassment is a good signature of a person to whom you can entrust valuable resources.
Not only are the findings useful for people seeking cooperative and reliable team members and business partners, but they also make for helpful dating advice.“Moderate(适度的) levels of embarrassment are signs of virtue. Our data suggests embarrassment is a good thing, not something you should fight.”said Matthew Feinberg, who led the study.
While the most typical gesture of embarrassment is a downward gaze to one side while partly covering the face, a person who feels shame, as distinguished(区别) from embarrassment, will typically cover the whole face, Feinberg said.
The results were got from a series of experiments. In the first experiment, 60 college students were videotaped describing embarrassing moments, such as making incorrect assumptions(假想) based on appearances. The college students also participated in the “Dictator Game” which is used in economics research to measure altruism(利己主义). For example, each was given 10 raffle tickets(奖券) and asked to keep a share of the tickets and give the reminder(提示物) to a partner.
The findings, published in the Journal of Personality and Social Psychology, showed that those who showed greater levels of embarrassment tended to give away more of their raffle tickets, indicating(﹦showing) greater generosity.
小题1:According to the passage, which of the following is thought to be reliable?
A.A person who feels shame. |
B.A person who hides his embarrassment. |
C.A person who shows his embarrassment. |
D.A person who gives away more raffle tickets. |
A.it’s useless to fight our embarrassment |
B.people should try to overcome their embarrassment |
C.embarrassed people are not good at doing business |
D.people who show embarrassment can be good business partners |
A.measure the students’ economic status |
B.test whether a student is generous or not |
C.determine the different levels of embarrassment |
D.record how each student reacts during embarrassing moments |
A.proved to be more generous | B.kept more of the raffle tickets |
C.didn’t care for raffle tickets | D.were less reliable |
“I think we are knocking at the door of immortality(永生) , " said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that"s a conservative estimate(保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.
However, many scientists who research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120,you know, could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."
小题1:By saying "we are knocking at the door of immortality", Michael Zey means ______.
A.they have got some ideas about living forever |
B.they are sure to find the truth about long living |
C.they believe that there is no limit of living |

A.people can live from 120 to 180 |
B.it is possible for humans to live longer in the future |
C.the human body is designed to last past about 120 years |
D.it is still doubtful how long humans can live |
A.using genes as well as nanotechnology |
B.the idea of living beyond the present life span |
C.a great push |
D.the conservative estimate |
A.No Limit for Human Life | B.Science, Technology and Long Living |
C.Living Longer or Not | D.Healthy Lifestyle and Long Living |
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸) has protected the city from the threat of flooding,but it was only designed to last until 2030 and close once every two or three years. About 21 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London"s flood risk area, so large scale flooding would be disastrous.
Paris
Over a sixweek period in July and August 2008,more than 11400 — mainly elderly people — died in France from dehydration (脱水) and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity (强度) are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have airconditioners installed in elderly care homes. But this is considered a shortterm solution, as the increase in demand for electricity also increases carbon emissions.
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower”, which uses a covering of bamboo to act as a natural airconditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coalfired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
