Article: In white shirt, blue pants, black cloth shoes and two pigtails, Jingqiu gives off an air of great "pure beauty" in Zhang Yimou's new movieUnder the Hawthorn Tree, which tells the story of the sad romance of Jingqiu and a handsome young man named Laosan set at the end of the "cultural revolution" (1966-- 1976). Before it was released, moviegoers foresaw what this "pure beauty" could be. Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu -- a character so innocent. She believes that simply lying on the same bed as a man will make her pregnant. It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has "eyes that are clear like a fountain on a mountainside". Born to an ordinary worker's family, the Shijiazhuang girl was in her final year of high school and working hard for a place in an art college. "If you have fair skin and clear eyes, as Jingqiu does, it is easy to look pure. Girls today wear so many jewels and make-up--that's the reason Zhang was not interested," said Du Yanlai, 17, of Chengdu. While some teenagers consider such "pure" beauty _ , others believe that it speaks of something soulful. Purity is all about an innocence that shines through from within, thinks 16-year-old Tan Mengxi of Nanjing. "Being pure can be simple, not having complicated thoughts and being inexperienced. However, it doesn't mean an ignorant or native person. So, a person is pure in his or her nature if he or she is always enthusiastic and able to deal with difficult matters independently. This purity doesn't pass with time, "she said.
Answer: Being simple, enthusiastic and able to manage things alone.
answer:
What's the real purity according to Tan Mengxi?

Article: Did you know that vegetables can grow in the climates they are not used to? Cool climate vegetables like asparagus are now able to be grown in places as hot as Hawaii. In Hawaii, marine engineers have been able to actually let you believe such vegetables that they are living in cooler climates. In that way they grow faster and taste better. What these engineers have been using is very simply cold sea water. How did they use it? They place pipes in the soil and cold water flowing through them cools the earth. This causes plant growth and enables gardeners in tropical climates to grow crops from cooler climates. Also some of these pipes are exposed to the air and they make the air "wet" and thus water the gardens. What especially makes people happy about this process is that nothing to the natural conditions is being used. Another new use for cold ocean water is to cool buildings. Engineers believe that for example the entire west coast of the prefix = st1 /United Statescould be air-conditioned using seawater.
Answer: Cool the soil.
answer:
What does the new system enable the gardeners to do?

Article: At Denver there was an crowd of passengers into the coaches on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank face expression and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed together. As they passed down the aisle of the coach the only available seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman's glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her face and a tender pink tingeing(,) her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard. "Well, Mr. Easton, if you will make me speak first, I suppose I must. Don't you ever recognize old friends when you meet them in the West?" The younger man aroused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand. "It's Miss Fairchild," he said, with a smile. "I'll ask you to excuse the other hand; "it's otherwise engaged just at present." He slightly raised his right hand, bound at the wrist by the shining "bracelet" to the left one of his companion. The glad look in the girl's eyes slowly changed to a bewildered horror. The glow faded from her cheeks. Her lips parted in a vague(,), relaxing distress. Easton, with a little laugh, as if amused, was about to speak again when the other forestalled him. The glum-faced man had been watching the girl's face expression with veiled glances from his keen, shrewd eyes. "You'll excuse me for speaking, miss, but, I see you're acquainted with(,) the officer here. If you'll ask him to speak a word for me when we get to the pen(,) he'll do it, and it'll make things easier for me there. He's taking me to Leavenworth prison. It's seven years for cheating." "Oh!" said the girl, with a deep breath and returning color. "So that is what you are doing out here? An officer!" "My dear Miss Fairchild," said Easton, calmly, "I had to do something. Money has a way of taking wings with itself, and you know it takes money to keep step with our crowd in Washington. I saw this opening in the West, and well, an officer isn't quite as high a position as that of ambassador, but--" "The ambassador," said the girl, warmly, "doesn't call any more. I needn't ever have done so. You ought to know that. And so now you are one of these brave Western heroes, and you ride and shoot and go into all kinds of dangers. That's different from the Washington life. You have been missed from the old crowd." The girl's eyes, fascinated, went back, widening a little, to rest upon the glittering handcuffs. "Don't you worry about them, miss," said the other man. "All officers handcuff themselves to their prisoners to keep them from getting away. Mr. Easton knows his business." "Will we see you again soon in Washington?" asked the girl. "Not soon, I think," said Easton. ." "I love the West," said the girl irrelevantly. Her eyes were shining softly. She looked away out the car window. She began to speak truly and simply without the gloss of style and manner: "Mamma and I spent the summer in Denver. She went home a week ago because father was slightly ill. I could live and be happy in the West. I think the air here agrees with me. Money isn't everything. But people always misunderstand things and remain stupid--" "Say, officer," shouted the glum-faced man. "This isn't quite fair. I'm needing a drink, and haven't had a smoke all day. Haven't you talked long enough? Take me in the smoker now, won't you? I'm half dead for a pipe." The bound travelers rose to their feet, Easton with the same slow smile on his face. "I can't deny a require for tobacco," he said, lightly. "It's the one friend of the unfortunate. Good-bye, Miss Fairchild. Duty calls, you know." He held out his hand for a farewell. "It's too bad you are not going East," she said, reclothing herself with manner and style. "But you must go on to Leavenworth, I suppose?" "Yes," said Easton, "I must go on to Leavenworth." The two men sidled down the aisle into the smoker. The two passengers in a seat near by had heard most of the conversation. Said one of them: "That officer is a good sort of man. Some of these Western fellows are all right." "Pretty young to hold an office like that, isn't he?" asked the other. "Young!" exclaimed the first speaker, "why--Oh! Didn't you catch on? Say--did you ever know an officer to handcuff a prisoner to his right hand?"
Answer: Because he was afraid Miss Fairchild would find the truth.
answer:
Why did the glum-faced man urge Easton to the smoker?
