[单项选择] By the time we had completed our preparations, the sky was beginning to grow rapidly lighter, although the sun was not yet above the horizon. We waited unpatiently, hardly daring to move or to whisper to one another. Suddenly, we heard the quick beating of wings and one of the birds we were looking for flew up from the valley beyond. He flied straight to the tree and settled on a thin branch, stripped bare of leaves, which grew diagonally upwards from the main trunk. Immediately he began to clean himself, combing with his beak the long soft feathers which grew from beneath his wings and extended past his tail in a glorious red cloud. Charles’’s camera, on a trial run, sounded unexcepted loud, but the bird took no notice and continued with his cleaning until at last he drew himself up and shook himself. Then, head held high, he called a single, loud, sharp note which resounded over the valley. He seemed in no hurry to begin his dance, as he continued to call for a quarter of an hour.

Corporations as a group offer a variety of jobs. Most large companies send people to colleges to interview graduating students with the required academic training. A large university may have more than 500 companies a year knocking on its door. Big firms are your best place for a job because their normal growth, employee retirements, and turnover (补缺工人数) create thousands of jobs nationwide each year. They are quite attractive for job seekers.
Corporations, however, illustrate the rule that the biggest isn’t always the best. Many small firms with just a few hundred employees have positions that may correspond with your profession goals, too. Such firms may not have the time, money, or need to send people around to your college; you’ll probably have to contact them yourself either directly or through an employment agency. Don’t ignore these little companies. They are perhaps beneficial for you. Their salaries are usually competitive and the chances for adv

[单项选择]Six years ago, a Miami woman walking through the hall of an office building casually noticed two men standing together.

Police investigators determined that the woman was the only witness who had seen the two suspects, and could possibly describe them. In an interview with police, her memory of the men proved disappointingly unclear.
Several days later, psychologist Ronald P. Fisher was brought in to obtain a more complete account from the woman. Fisher’s interview produced a breakthrough (突破)—the woman reported a clear picture of one of the suspects. She then recalled several details about his appearances. This information gave police important leads that enabled them to arrest the suspects and close the case.
Police investigators sought the help from Fisher because of his rich knowledge in conducting the so-called cognitive (认知的) interview, a kind of memory-rebuilding pro
A. strengthening her memory
