[EX Q]: Article: Recently Chinese society has seen a flowering of a new vocabulary. Perhaps the most interesting has been the division of people into tribes (zu in Chinese). The pains of the yi zu, or the ant tribe, have been well-known --- recent graduates from outside the main cities who move to urban areas, live cheaply and work hard, often in low-paid jobs. Perhaps less well-known are the ken lao zu, the bite-the-old tribe, those between 25 and 35 who are out of work, still at home and depending completely on Mum and Dad. Many of the tribes, inevitably , are made up of people looking for love. There is the jia wan zu, the marry-the-bowl tribe. These are young women searching for the most stable husbands, the ones who hold government jobs. The shan hun zu, or lightening-marriage tribe, marry fast and sometimes separate faster. They should not be confused with the yin hun zu, the hidden-marriage tribe. These are women in their 20s who hide the fact that they are married. And if you can only afford a postage stamp of an apartment, you're probably a member of the wo ju zu, the snail-house tribe. You can belong to more than one tribe. Most members of the ant tribe also belong to the ben ben zu, the rush-rush tribe, to which, in fact, most urban Chinese belong. All that rushing around can create a lot of anger, leading to the nie nie zu, the crush-crush tribe, so named because they go into supermarkets and take out their anger by standing in the passages crushing packets of instant noodles. Another famous one is the yue guang zu, or moonlight tribe, so named because the Chinese characters for "moonlight" sound the same as the phrase "spend all your monthly salary". Their parents save every coin, but life for these young people is just to spend, spend and spend.
Answer: Graduates from the countryside .
[EX A]: Who probably belong to the ant tribe?

[EX Q]: Article: As any parent with an iPhone or an iPod Touch knows, mobile apps can be an engaging and entertaining experience for kids. Now, a new study of PBS Kids suggests that the experience can be an educational one as well. The study, which was administered by PBS under a grant from the Department of Education, first tested the vocabulary level of a group of 90 Title 1 school children, aged 3 to 7. Then, the children were each given two weeks with an iPod Touch loaded with the Martha Speaks Dog Party app created by PBS Kids. The study monitored how the children used the iPod, during what hours, and in what context. On average, the study found that kids played with the iPod Touch for a total of 5 hours across the two weeks, with half that time spent playing the Martha Speaks app. At the end of the two week trial, the children were given another vocabulary test, which revealed an increase in vocabulary acquisition by as much as 31 per cent. The study findings are particularly useful as smart phones and mobile devices have become increasingly popular among families and parents are faced with a proliferation of mobile apps designed for kids. According to a recent Nielsen study, smart phone usage is 12% higher in households with children than other households. "Mobile apps can be a great learning tool in the hands of children," said Lesli Rotenberg, SVP, Children's Media, PBS. "This research is important in helping to better understand and guide the development of new apps that improve the value of children's screen time with significant educational outcomes." So what does it all mean? At best, it provides more evidence that mobile devices and apps do indeed have educational value and could be an important part of the child-learning process for many years to come.
Answer: It's too early for kids to use smart phones
[EX A]: What would be the best title of the text?

[EX Q]: Article: Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers hoping to sell their products. The endless choice gives birth to anxiety in people's life. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors. It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing: no choice, no anxiety.
Answer: Companies and advertisers are often misleading about the range of choice.

Why do more choices of goods give rise to anxiety?
