[EX Q]: 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.
[EX A]: A

[EX Q]: Article: All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take upmost of the water. Land plants without roots do exist, however. Those greenish-yellow lichens you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots. Even among the flowering plants, one finds rootless forms. These flowering plants are "the higher plants" because they evolved recently and are thus considered higher on the evolutionary scale . In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees growing high above the streets on the insulation of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.
Question: Wood becomes larger because of _ .
Options: (A) dead cell walls (B) water entering dead cells (C) the growth of cells (D) the death of cells
[EX A]: B

[EX Q]: Article: Getting paid to talk about the World Cup is a great job. I'm not a football commentator , though-just an English teacher in Japan. I come to Japan two years ago, and didn't think I would stay, but Japan has that effect on you. _ . I think it's best to teach in a bigger city where there are other foreigners to mix with, rather than a small town where English teachers often complain of feeling like a goldfish in a bowl. Many people choose to live in Tokyo, of course, which is good for the nightlife factor. But I'd say that for general quality of living, cities of neither too large nor too small, like Sapporo where I live, are better choices. I teach English privately, which means I'm my own boss. If you want to devote yourself to private teaching, it's well worth doing a TEFL course first, because your lessons will be much better for it. The problem with private teaching is finding students; it took me a year to build up a full schedule of private lessons, so I started out teaching in schools part-time. Most of my foreign friends here work full-time for big English conversation schools. The salary is fine to live on, but whether you can save money depends on how much going out and traveling you do here. The schools are unwilling to take time off -even teachers with tickets for the England-Argentina game had trouble getting the day off.
Question: From the passage we know in Japan the writer likes to live in _ .
Options: (A) Tokyo (B) a small town (C) a city of middle size (D) a big city
[EX A]:
