(Question)
A German taxi-driver, Franz Bussman, recently found his brother who was thought to have been killed twenty years ago. While on a walking tour with his wife, he stopped to talk to a workman. After they had gone on, Mrs. Bussman said that the workman was closely like her husband and even suggested that he might be his brother. Franz laughed at the idea, pointing out that his brother had been killed in action during the war. Though Mrs. Busman knew this story quite well, she thought there was a chance in a million that she might be right. A few days later, she sent a boy to the workman to ask him if his name was Hans Bussman. Needless to say, the man's name was Hans Bussman. And he really was Franz's long-lost brother. When the brothers were reunited, Hans explained how it was that he was still alive. After having been wondered towards the end of the war, he had been sent to hospital and was separated from his unit . The hospital had been bombed and Hans had made his way back into Western Germany on foot. Meanwhile, his unit was lost and all records of him had been destroyed. Hans returned to his home, but the house had been bombed up. Guessing that his family had all been killed during an air-raid , Hans settled down in a village fifty miles away where he had remained ever since. How to understand the sentence "There was a chance in a million that she might be right."? A) It was impossible for her to be right. B) She had no chance to meet his brother any more. C) There were many chances for her to meet his brother again. D) There was a little possibility of what she suggested, though little.

Ques: American researchers have discovered that human brains and sleep patterns are confused by devices that give out bright lights. Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of _ . Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it. A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone called melatonin that makes us sleepy. Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive during the night when the brain thinks it should be dark. Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp light doesn't affect the brain as it does not look straight into a person's eyes. "Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating to the brain to make it more awake and delay your ability to sleep," Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN. "And I think more importantly, it could also be enough to affect your circadian rhythm. This is the clock in your brain that determines when you sleep and when you wake up. " Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, "I wish people would just take a boring book -- an oldfashioned book -- and read by a lamp." The bedside lamp light doesn't affect the brain because _ . A) it doesn't give out blue light B) it's not as bright as your laptop C) it doesn't enter your eyes directly D) it is adjustable

Ques:It takes two to duet , and one question for scientists is how these coordinated performances arise -- in birds. Are they the result of cooperation, a way in which one pair signals to others that they've got it together? Or are they the result of conflict, evolving to avoid one partner's song interfering with the other's? A study of duetting in Peruvian warbling antbirds suggests that it might be a little of both, and that context is everything. Joseph A. Tobias and Nathalie Seddon of the University of Oxford show in Current Biology that sexual conflict can cause the female of a pair that normally cooperates to "jam" the male's song by singing over it. The researchers exposed antbird pairs to recorded songs of other antbirds and monitored the songs the pairs produced. In one experiment, they played the songs of an intruding pair. In this case, the resident pair "both are likely to lose their territory, so both should cooperate," Dr. Tobias said. And they do. They produce a coordinated duet that in effect tells the intruders to keep away. But when the researchers played the song of a single female, the pair behaved differently. "You'd expect the resident female to be highly motivated to defend her position in the partnership," Dr. Tobias said. And that's what occurs. The male sings its heart out, flirting with the single female, and the female of the pair does its best to interfere with the song by singing over it, apparently to make her mate less attractive to the other female. "It's clear that the male doesn't like what she's doing," Dr. Tobias said. The behavior "breaks up what is otherwise a very cooperative situation into a more complicated signal," he added. It's the first evidence of this kind of signal jamming among pairs, Dr. Tobias said. And in that it leads the male to alter its song to avoid the female's interfering notes, it shows that this kind of conflict could, over a long period, drive the evolution of coordinated song. What is the key factor of antbirds' duet? A) Their cooperation. B) Their conflict. C) The context. D) Their instinct.
