问题 单项选择题

下列说法错误的是( )。

A.收缩压在90~140毫米汞柱之间属正常血压

B.人的耳朵比别的地方更怕冷是因为其太薄而容易散发热量

C.抗生素无法治疗由病毒感染而引起的疾病

D.尿糖检测是诊断糖尿病的主要方法

答案

参考答案:B

解析: 正常的血压范围是收缩压在90~140mmHg(12.0~18.7kpa)之间,舒张压在60~90mmHg(8.0~12.0kpa)之间,高于这个范围就可能是高血压或临界高血压,低于这个范围就可能是低血压。A项正确。耳朵处于血管末梢地位,本来温度就较低,再加上接触空气的面积大,热量很容易散发,所以耳朵比别的地方更怕冷。B项说法错误,符合题意。抗生素主要针对的是细菌性疾病,C项说法正确。诊断糖尿病最重要的是检验尿糖,看看尿中是不是含有葡萄糖。D项说法正确。故本题选B。

完形填空

[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch(门廊) and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.

[2] “Go fight somewhere else!” she shouted, worried her plants would getdamaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.

[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning(呻吟) in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.

[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(发抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.

[5]The Klevens then learned what had happened. Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.
