Q: Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery   that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions   are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode   made of many carbon-based graphene   sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters   of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered   by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week.  "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available within five years, the researchers said.

Q: Article: NBA commissioner David Stern was in Orlando on Thursday night, getting ready for Sunday's All-Star Game. Of course, all he could talk about was the only player anyone wants to talk about these days: New York Knicks guard Jeremy Lin. Hours before Lin took the court against the Heat, a few hundred miles South down I-95 in Miami, Stern told reporters that Lin's instant popularity hasn't ever been matched in sports history, not even by Sunday's biggest names, LeBron James or Kobe Bryant. The Associated Press had the details. "I haven't done a calculation, but it's fair to say that no player has created the interest and the craze in this short period of time, in any sport, that I'm aware of like Jeremy Lin has," Stern said Thursday. Lin, an undrafted guard from Harvard, has become the NBA's biggest story since coming off the Knicks' bench earlier this month to lead them to nine wins in 11 games heading into their matchup with Miami on Thursday night. With Lin's popularity in Asia as the league's first American-born player of Chinese or Taiwanese descent, and with the religious community because of his strong Christian faith, Stern says he's "never quite seen anything like" the attention on Lin. "It's fascinating," Stern said after the All-Star Jam Session opening ceremonies. The top five videos on NBA.com since Feb. 4, when Lin joined the circulation, are all Lin or Knicks related. Lin went from 190,000 followers on Sina, China's version of Twitter, on Feb. 2 to more than 1 million as of Feb. 16. Indeed, Lin's popularity is so _ that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday, a game that includes the NBA's best rookies and sophomores. Lin is in such high demand that all of the game's other participants will meet with the media following a team practice on Friday while Lin will have his own, separate press conference later in the night. This is Jeremy's world, folks. We're all just living in it. Even David Stern and the rest of the league's All-Stars, at least for the moment. 
 Question: The following statements about Jeremy Lin's instant popularity are true EXCEPT that   _  . 
 Options: (A) Jeremy Lin led New York Knicks to win all the recent games this month (B) David Stern said Lin was the only instant popular player in NBA's history (C) Lin has become the NBA's greatest story though he was an undrafted guard (D) no player has created the interest and the enthusiasm in such a short period of time 
 Asnwer: B

A: No

Q: Article: Parents are fuelling bad behavior among their children by attempting to "buy" their love with expensive gifts nowadays. Over recent decades we seem to have created a "must have" culture among our young people. Many mothers and fathers believe they are "failing as parents" if they are unable to ensure that their children have the latest toy, electronic devices (the lap-top, cellphones, Game Boy, etc.) along with their friends. In many cases, families also feel pressured to enroll   children in "'every interest club or after-school activity that is available" to fill up their time like most of the other children. But experts warned that the move might affect "precious family time" negatively. Graham Gorton, chairman of the Independent Schools Association, said that parents spent too much time filling their children's lives, which had a series of negative effects on "the very precious family time that exists". "It seems that those times when a whole weekend without planned work was seen as a luxury   and a perfect opportunity to spend time together and share those valuable moments of childhood are long gone," Mr. Gorton said. "As a child I only once said that phrase that parents feared 'I'm bored'. Immediately my mother took action and produced a list of jobs and then insisted that I complete every one of them. Though l didn't think cleaning all the floors could really get rid of my boredom, I enjoyed the feeling of staying at home with my mother and brothers." Earlier this year, some researchers suggested that relatively wealthy parents were sometimes guilty of failing to teach basic social skills to children. "Often, it's the rich middle classes that buy off their children through the computer and the TV. That then sets them apart from their family, and then the parents are surprised when their child isn' t coming to school." 
 Question: What does the "must have" phenomenon refer to based on the passage? 
 Options: (A) That children must have what other children have. (B) That children must have proper pressure to work hard. (C) That children must have special skills to ensure a better future. (D) That parents must have patience to know their children better.
