[EX Q]: Article: It does not come as a surprise that Dubai has a growing problem with "tragic". The local rulers have explored all the conventional ways to get traffic moving again,including higher prices for parking,fuel and insurance. But at a recent conference in Hamburg, Hussain Lootah said that the city may adopt a more strict approach: setting an income level for vehicle ownership. Mr Lootah's approach is unlikely to be copied widely, but mayors of other big cities around the world are starting to think about taking severe actions of their own, including complete car bans in inner cities.But the efforts may not be enough to reduce traffic and pollution. The problems will only get worse: the number of vehicles sold globally each year will grow from around 80 million today to more than 100 million by the end of the decade, according to IHS Automotive. There are already a handful of car-free communities around the world.But these are typically small and often tourist destinations that seek to create a throwback(;) in time, such as Sark Island, in the English Channel. The largest car-free urban area is probably Venice, where it is impossible to build roads and bridges to link the more than 100 small islands the city sits on. Yet pedestrian malls and other car-free zones keep popping up in cities around the world. Some cities are considering ways to limit central city access to "green" machines, such as battery-electric vehicles. Hamburg is perhaps the furthest along. Such extreme plans may fly in a city such as Hamburg. But in many other cities the political resistance even to less far-reaching measures is hard to overcome. Michael Bloomberg, New York's former mayor, tried twice to introduce a jam charge for much of Manhattan, but his plans were rejected by state lawmakers.
Question: It is still hard to reduce traffic problems, because _ .
Options: (A) Mr Lootah's approach will be copied widely. (B) mayors take gentle measures toward them. (C) more vehicles will be sold globally each year. (D) complete car bans in inner cities are not made.

[EX Q]: Article: Selfie is a photograph taken of oneself, typically with a smartphone or webcam and uploaded to a social media website. In the digital age, selfies have taken off in a way that no one could have predicted. The art of the selfie is one that lots of people have practiced and perfected in recent years. A recent study shows 91 percent of teens have posted a photo of themselves online. Some celebrities are regular selfie posters, too. It seems that selfies are more than just a trend. They are here to stay. Why are selfies so popular? The appeal of selfies comes from how easy they are to create and share. And posting selfies is popular for another reason: you can control your own image. "I like having the power to choose how I look," admits Samantha, a 19-year-old girl from Missouri, "even if I'm making a face." Actually, the most common selfie is the one where you look cute, partly because it's a quick way to get positive comments about your appearance. "If I feel pretty, I take one," says Andrew, a 23-year-old girl from Maryland, "when other people Like it, it's a mini boost of confidence." Sure, showing off a new coat or that you're at a cool event is fun, but can be a trap to fall in. There's a danger that your self-respect may start to be tied to the comments and Likes you get when you post a selfie, and they aren't based on who you are--they are based on what you look like. Seeking validation is totally normal, and it's a healthy way for teenagers to develop their identity. But with social networks, where it's easy to get quick approval almost constantly, the selfie thing can quickly go out of control. It may even start to feel like an addiction: when you get a "LIKE", you're up. But when you get nothing, your confidence can decrease quickly. Overall, opinions vary on selfie culture. It's up to you to shape the future of the habit. Ask yourself: are my selfies for fun, or do I need the comments? If you belong to the latter, it's recommended that you change your view. That could mean cutting selfies out entirely or just cutting down and making them more fun. So maybe you like to travel, or read or dance, or create crazy 3-D nail art...post them! Take it from us: it's so much more interesting.
Question: According to the passage, selfie is a type of _ .
Options: (A) photo (B) smartphone (C) webcam (D) website
[EX A]: A

[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.
Question: Who probably belong to the ant tribe?
Options: (A) Graduates in their 20s. (B) Young women looking for love. (C) People between 25 and 35. (D) Graduates from the countryside .
