Passage Two:It is simple enough to say that since books have classes fiction, biography, poetry—we should separate them and take from each what it is right that each should give us. Yet few people ask from books what books can give us. Most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices. If we could banish all such preconception when we read, that would be an admirable beginning. Do not dictate to your author; try to become him. Be his fellow worker and accomplice(同谋). If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read. But if you open your mind as widely as possible, then signs and hints of almost imperceptible finess (委婉之处), from the twist and turn of the first sentences, will bring you into the presence of a human being unlike any other. Steep yourself in this, acquaint yourself with this, and soon you will find that your author is giving you, or attempting to give you, something far more definite. The thirty two chapters of anovel—if we consider how to read a novel first—are an attempt to make something as formed and controlled as a building but words are more impalpable than bricks, reading is a longer and more complicated process than seeing. Perhaps the quickest way to understand the elements of what a novelist is doing is not to read, but to write; to make your own experiment with the dangers and difficulties of words. Recall, then, some event that has left a distinct impression on you—how at the corner of the street, perhaps, you passed two people talking. A tree shook; an electric light danced; the tone of the talk was comic, but also tragic; a whole vision, an entire conception, seemed contained in that moment.Please choose the best answer to the following questions:What does the author mean by saying “Yet few people ask from books what books can give us.”?______

A. The author means that lots of people read few books.
B. The author thinks that readers have only absorbed part of knowledge in books.
C. The author holds that few people have a proper idea about what content some kind of books should include.
D. The author considers that readers can scarcely understand most of the books.

Passage Two:Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just "mental noise" the random byproducts of the neural repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermostat, regulating moods while the brain is "off line." And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better. "It’s your dream," says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center, "if you don’t like it, change it."He link between dreams and emotions shows up among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events-until, it appears, we begin to dream.And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time it occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.At the end of the day, there’s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people’s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep-or rather dream-on it and you’ll feel better in the morning.Choose correct answers to the question:By saying that “dreams are part of the mind’s emotional thermostat," he researchers mean that _______.

A. we can think logically in the dreams too
B. dreams can be brought under conscious control
C. dreams represent our unconscious desires and fears
D. dreams can help us keep our mood comparatively stable
