[EX Q]: Article: Children's lives have changed greatly over the last 50 years.But do they have a happier childhood than you or I did? It's difficult to look back on one's own childhood without some element of nostalgia .I have four brothers and sisters, and my memories are all about being with them.Playing board games on the living room floor, or spending days in the street with the other neighborhood children, racing up and down on our bikes, or exploring the nearby woods.My parents scarcely appear in these memories, except as providers either of meals or of severe blame after some particularly risky adventure. These days, in the UK at least, the nature of childhood has changed dramatically.Firstly, families are smaller, and there are far more only children.It is common for both parents to work outside the home and there is the feeling that there just isn't time to bring up a large family, or that no one could possibly afford to have more than one child.As a result, today's boys and girls spend much of their time alone.Another major change is that youngsters today tend to spend a huge amount of their free time at home, inside.More than anything this is due to the fact that parents worry far more than they used to about real or imagined dangers, so they wouldn't dream of letting their children play outside by themselves. Finally, the kind of toys children have and the way they play is totally different.Computer and video games have replaced the board games and more interesting activities of my childhood.The irony is that so many ways of playing games are called "interactive".The fact that you can play electronic games on your own further increases the sense of loneliness felt by many young people today. Do these changes mean that children today have a less relaxing childhood than I had? I personally believe that they do, but perhaps every generation feels exactly the same.
Question: Which is NOT a reason for the changes?
Options: (A) Families are smaller today (B) Toys can be played by children alone at home (C) It's too dangerous to play outside (D) Parents worried too much about their children
[EX A]: C

[EX Q]: Article: As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper. Procrastination is the thief of time and a lot of students suffer from it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely, are doing nothing either. Paralyzed by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell . According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong. Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is nonsense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones. Pelling also points out that procrastination feels particularly delinquent in a society that thinks of speedy action as admirable, and, at times, even as a moral good. Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is "designed" to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.
Question: Which behavior belongs to procrastination?
Options: (A) Never dream away the time. (B) Always complete the tasks ahead of time. (C) Never put off till tomorrow what should be done today. (D) Always wait to work until the "good mood" or "good time".

[EX Q]: Article: Do you love Beats headphones, True Religion jeans, and UGG shoes? These are some of the most popular brands around. They are also expensive. But some experts say they are not much better than cheaper brands. For example, Jim Wilcox works for Consumer Reports. He tested all kinds of headphones. He says that $80 Koss Pro headphones provide basically the same quality and comfort as Beats. So why do people pay twice or even 10 times as much for the hottest brands? Experts say it's because fashionable, expensive brands send a message. Brands say "I belong" or "I can afford it." Some people think that expensive brand names are worth the price. They say that some designer clothes really are top quality and that they last longer than cheaper brands. Some teenagers choose to wear popular brands because these brands make them feel good about themselves. Alexandra Allam, 17, likes to buy brand-name products. "I'd rather spend the extra money to get something I know I'll be satisfied with," she says. Her friend Emmy Swan agrees, saying "As long as you can afford it, it seems reasonable to buy what you want." But not all teenagers agree. "Spending hundreds of dollars for designer sunglasses is stupid and unreasonable," says Daniel Steinbrecher, 16. "It's fake happiness." People who are against wearing expensive brand names say that many designer brands aren't any better. "It's wasteful to buy things just because they are popular," says Edmund Williams, 15. "You'll feel better if you buy things because you like them. If you have extra money to spend, it would be better to give it to people in need."
Question: The example of Jim's report wants to tell us _ .
Options: (A) popular brands make people comfortable (B) Koss Pro headphones are better than Beats (C) the hottest brands are of the highest quality (D) less-known brands may offer the same quality as name brands
