President Barack Obama rode a bicycle at the White House Science Fair on April 2
题型：不详难度：来源：
President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn’t an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration (过滤) system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida.
Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project.“We were hoping President Obama would ride the bike, but we didn’t actually expect him to,” Payton told TFK. “ It really meant a lot.” Kiona agreed. “It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation,” she said.
The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable(便携的), bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. “ They can take it to places after natural disasters so that water can be clean for the people there,” said Payton.
Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to stimulate students interested in STEM (Science, Technology, Engineering, Maths).“Well, if you’re a young person and you produce the best experiment or design, you ought to be recognized for that achievement,” Obama said when he first announced the fair.
President Obama praised the projects during a speech to attendees after the fair. “The science fair projects of today could become the products and businesses of tomorrow,” he said. “If you’re inventing things in the third grade, what are you going to do by the time you get to college?”

"Hey, don"t read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. “Don’t read in poor light!” This is one of the common beliefs that are supposed to help us live a healthy life. Such beliefs are, however, without scientific basis(根据), according to a paper published recently in the British Medical Journal.
Do you believe in the following sayings?
Reading in poor light ruins your eyesight.
In poor light, you might blink (眨眼) more, suffer from drying and have trouble focusing. But most of eye experts believe it is unlikely to do any damage forever.
We must drink at least eight glasses of water a day.
In 1945, the Nutrition Council in US suggested that people need to drink 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.
We only use 10 percent of our brains.
This idea appears as early as 1907. People have long argued about our power of self-improvement and our brains’ possible abilities. But X-rays show that no area of the brain is silent or inactive.
Shaving your legs causes hair to grow black faster and thicker.
This theory is also illusion. Studies say that shaving has no effect on the thickness or rate of hair growth. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer (更细).
小题1:What does the paper say about some common beliefs?| A．They are useful knowledge in life. | | B．They help us live in healthy ways. | | C．They are well-known theories. | | D．They do not have scientific basis. |

小题3:The underlined word “illusion” in the last paragraph probably means “_________”.| A．a wrong idea | B．a powerful evidence | | C．an interesting story | D．a clear instruction |
小题4:This passage is most likely to be found in __________ . | A．a newspaper | B．a guide book | | C．a history textbook | D．an advertisement |

In 1980，Candy Lightner’s 13-year-old daughter Cad was killed by a drunk driver as she walked down a suburban street in California. “I promised myself on the day of my daughter’s death that I would fight to make this needless accident count for something positive in the years ahead,” Candy Lightener later wrote.
The drunk driver received a two-year prison sentence. However, he avoided prison by serving time in a work camp and a halfway house. Ms. Lightner was very angry about that and so organized Mothers Against Drunk Drivers (MADD), which later changed to Mothers Against Drunk Driving. The aim of her organization was to raise public awareness of the serious nature of drunk driving and to promote tough legislation against the crime.
Before Ms. Lightner’s MADD, intoxication (醉酒), including drunk driving, was not taken seriously. Intoxication was often used as an excuse for otherwise unacceptable behavior: “I didn’t know what I was doing—I was drunk.”
Candy Lightner appeared on major television shows, spoke before the US Congress, addressed professional and business, groups, and worked tirelessly for years to change public attitudes, change judicial(审判的) behaviour, and promote tough new legislation. Ms. Lightner left MADD because the organization that she herself created is changing its focus. “I didn’t start MADD to deal with alcohol. I started MADD to deal with the issue of drunk driving.”
The President of the United States awarded her the President’s Volunteer Action Award and she was the subject of the movie “Mothers Against Drunk Drivers: the Candy Lightner Story”.
小题1:One of the purposes of MADD was to______ .| A．make the public aware of the danger of drunk driving | | B．fight against the drunk hit-and-run drivers on the road | | C．make new laws against crimes caused by drinking | | D．warn people not to drink alcohol while driving |
小题2:which way didn’t Ms. Lightner use to achieve her MADD’s goals?| A．Talking on major TV shows. | | B．Giving a talk to businessmen. | | C．Applying for a job with the government. | | D．Giving suggestions to the US Congress. |
小题3:We can learn from the passage that______.| A．the drunk driver had not been caught | | B．drunk driving didn’t receive enough attention before MADD | | C．Candy Lightner played a leading role in a film | | D．MADD didn’t get much support from society |
小题4:What would be the best title for the passage?| A．Ways to prevent drunk driving | | B．Purposes of founding MADD | | C．New law against drunk driving | | D．Candy Lightner and her MADD |

"Gangnam Style" by singer Psy from Korea, is a popular song, but its extraordinary global success is really the result of its music video, which is a great piece of genius. On September 22nd, Guinness World Records listed "Gangnam Style" as the most-liked video in the history of YouTube. It"s been performed at West Point (West-Point Style), and Google"s CEO, has done the "Gangnam Style" horse dance at the company"s office in Seoul. Even Samsung is trying to make Psy the new model for the latest type of fridge.
The song"s global popularity is such that the vast majority of people who enjoy it don"t speak Korean, and have no idea what it is about. That"s fine --- part of what makes "Gangnam Style" so fun is, like international pop music, the difficulty in understanding it. When we sing along, "Hey, sexy lady", we don"t really know what we"re singing about.
The joy of incomprehensibleness is familiar to anyone who loves pop music from elsewhere. Anthony Lane, in his 2010 review of the Eurovision Song Contest, Only Mr. God Knows Why, used "Eurovision English" as one of its chief pleasures. It"s "a complex tongue, spoken nowhere else, which raises the heartfelt poetry (诗意) but absolute nonsense to a level of what sci-fi writers could only have dreamed. " In similar ways, "Gangnam Style" is just an over-the-top video where a fat man does a funny dance and sings repetitive words that don"t make sense to most of us.
But on the other, the magic of the song also lies in its funny dance, which reflects not just cultural morals specific to Korea, but cultural values easily recognizable to western viewers. This song"s words may be in Korean, but its scenes are in clear American. The dance moves are simple enough to copy.
Nonsense, in other words, forces us to let down our guards. It makes us relax, and asks us to let in all sorts of feelings from which, otherwise, we might distance ourselves. "Gangnam Style" happens to be so interesting because of its incomprehensibleness.
小题1:Some complex languages are used in pop music because _______.| A．singers regard it as one of the chief pleasures at the concert | | B．they make the music hard to understand but poetic and attractive | | C．the music can sound more pleasant and beautiful to the audience | | D．people like listening to the music which makes special sense to them |
小题2:What is true about the popularity of "Gangnam Style"?| A．It was considered as the most popular video on the Internet. | | B．It makes people amused and removes their emotional guards. | | C．Its dance only reflects cultural and morals specific to Korea. | | D．Psy, its singer, has been the new model for Samsung . |
小题3:What does the underlined word "incomprehensibleness" mean in Paragraph 3?| A．Being interesting to listen to. | B．Being simple enough to copy. | | C．Being complex and repetitive. | D．Being difficult to understand. |
小题4:The text is mainly about ________.| A．how "Gangnam Style" becomes popular among the youths | | B．why "Gangnam Style" is popular even if few people understand it | | C．how Psy gains worldwide success through his talent and hard work | | D．what emotions and cultural morals Psy wants to convey with his song |
