Question: 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.

Answer: C

Question: Article: Every year on my birthday, from the time I turned 12, a white gardenia was delivered _ to me at my house. No card or note came with it. Calls to the florist were always in vain ---- it was a cash purchase. After a while I stopped trying to discover the sender's identity. But I never stopped imagining who the anonymous sender might be. My mother often contributed to these imaginings. She'd ask me if there was someone for whom I had done a special kindness who might be showing appreciation. Perhaps the neighbor I'd help when she was unloading a car full of groceries. Or maybe it was the old man across the street whose mail I retrieved during the winter so he wouldn't have to venture down his icy steps. When I was 17, a boy broke my heart. The night he called for me the last time, I cried myself to sleep. When I awoke in the morning, there was a message scribbled on my mirror in red lipstick: "Heartily know, when half-gods go, the gods arrive." I thought about that quotation from Emerson for a long time, and I left it where my mother had written it. When I finally went to get the glass cleaner, my mother knew everything was all right again. I don't remember ever slamming my door in anger at her and shouting, "You just don't understand!" because she did understand. One month before my high-school graduation, my father died suddenly of a heart attack. My feelings ranged from grief to abandonment, fear and over-whelming anger that my dad was missing some of the most important events in my life. I became completely uninterested in my upcoming graduation, the senior-class play and the prom-events that I had worked on and looked forward to. But my mother, in the midst of her own grief, would not hear of my missing out any of those things. The day before my father died, she and I had gone shopping for a prom dress and found a spectacular one. Wearing it made me feel like a princess, but it was the wrong size, and when my father died the next day, I forgot all about the dress. My mother didn't. The day before the prom, I found that dress-in the right size, draped over the living room sofa, presented to me -- beautifully, artistically and lovingly. I didn't care about having a new dress, but my mother did. She wanted her children to feel loved and lovable, creative and imaginative. My mother died when I was 22, only ten days after I was married. That was the year the gardenias stopped coming.
Question: Why did Mother try to arouse the author's imagination about the gardenia sender?
Options: (A) Because she wanted her child to feel cherished and loved not just by her but by the world. (B) Because she had a great curiosity like a child. (C) Because she was romantic and she once experienced such the same thing at her young age. (D) Because she wanted to give her child some tips about the gardenia sender.

Answer: A

Question: Article: Ernest Hemingway was born in Oak Park, Illinois, on July 21st, 1899. Influenced by his father, he enjoyed camping, fishing and hunting at his early age. In 1917, after graduation from high school, Hemingway began his writing career with The Kansas City Star. And then, after being rejected for army service in World War I because of poor vision, he volunteered to serve as a driver for an American ambulance unit in France. In 1918, he transferred to duty on the Italian front, where he was seriously wounded in an explosion. After his recovery, he returned home. He worked for The Toronto star, covered the Greco-Turkish war as a foreign reporter, and then returned to Paris, which was a city full of intellectual life, creativity, and genius after the war. In Paris, where he accomplished a revolution in literary style and language, his first book, Three Stories and Ten Poems, appeared in 1923, and was followed by a short story collection In Our Time, which marked his entry to American literature in 1925. Hemingway's status as a remarkable writer of his time was confirmed with the publication of A Farewell to Arms in 1929. The novel represented a farewell both for war and for love. In 1937, he became a foreign reporter covering the Spanish Civil war. Three years later, he published For Whom the Bell Tolls. Set in Spain during the Civil war, the novel restated his view of love found and lost and described the tough spirit of the common people. In 1912, the same judgment was reflected in his portrait of fisherman, Santiago, with an _ spirit in defeat, in The Old Man and the Sea, which was awarded the Pulitzer Prize in 1953. Hemingway won the Nobel Prize in Literature in 1954. With one of the most important influences on the development of the American short story and novel, Hemingway has seized the imagination of the American public like no other twentieth-century author. He died by suicide, in Ketchum, Idaho, in 1961.
