A.大多发病于12~15岁

B.运动抽动症状此起彼伏,并渐向上肢或下肢发展

C.少数表现为简单的发声抽动

D.首发部位常为面部某肌群

E.抽动常可受意志克制数分钟到数小时

答案

参考答案:A

解析:此题考点为短暂性抽动障碍的临床表现。短暂性抽动障碍:又称抽动症,为最常见类型。主要表现为简单的运动抽动症状。多首发于头面部,如眨眼、耸鼻、皱额、张口、侧视、摇头、斜颈和耸肩等。少数表现为简单的发声抽动症状,如清嗓、咳嗽、吼叫、嗤鼻、犬叫或"啊"、"呀"等单调的声音。也可见多个部位的复杂运动抽动,如蹦跳、跑跳和拍打自己等。部分患者的抽动始终固定于某一部位,另一些患者的抽动部位则变化不定,从一种表现形式转变为另一种。例如,开始为眨眼,持续一、两个月后眨眼消失,继之以斜颈。还有部分患者可能表现为多个部位的运动抽动症状,如有皱额、斜颈和上肢抽动等。这类抽动障碍起病于学龄早期,4~7岁儿童最常见,男性为多。抽动症状在一天内多次发生,至少持续2周,但不超过1年。

     A small man with a fat stomach got on the train at the last station before the frontier (边境). He carried a

paper bag. And four feet of ducks (鸭子) could be seen under the cover. The man found an empty seat, put the

bag in the middle of the floor, took out a newspaper and began to read.

     Then a policeman came in. Of course he saw the bag with the ducks' feet at once and said, "Whose is that

bag?"

     Nobody answered. The policeman repeated the question, and said, "I shall have to take it away from the

owner. Food mustn't be taken out of country."

     "Well, then," said the small man with a fat stomach. "Hurry up and take it away. We want to go home." The

policeman took the bag and went on to the next carriage (车厢).

     At the next station, when they were safely across the frontier, the small man got up, smiled at other

passengers and said, "I hope that they'll enjoy the ducks' feet. The rest of the bag had nothing but rubbish in it."

Then he opened his coat and pointed to another bag he was carrying under it. It was tied over the stomach,

which was not really fat. "I have the rest of the two ducks here," he said. With these words, he got off the train.

     But while he was happily walking to the exit with the bag in his hand, a policeman came up to him, saying,

"Hey, man! Foreign food mustn't be brought in."
