【题目】2016年6月19日,美国国家科学院预言:在2020年的某一天,美国南部的一些城市,在五彩斑斓的极光光幕过后,电网会突然变得闪烁不定,灯光在瞬时明亮后将会停电,一分半钟之后,这个大停电现象将会遍及美国整个东部地区,甚至整个欧洲以及中国、日本等区域也会同样经历这样的灾难,而这场灾难仅仅于太阳打了一个强烈的“喷嚏”。据此回答下列问题。

1】材料中所述的太阳打了强烈的喷嚏极有可能是( )

A. 太阳耀斑爆发 B. 太阳爆炸 C. 太阳辐射增强 D. 太阳辐射减弱

2】该喷嚏还可能产生的明显影响不包括( )

A. 短波通讯中断 B. 信鸽丢失 C. 指南针失灵 D. 地球公转速度的变化

【答案】

1A

2D

【解析】

1 根据题干中给出的材料“看到极光” “电网会突然变得闪烁不定,灯光在瞬时明亮后将会停电”等这些现象,是由于太阳的一个 “喷嚏”产生的,根据太阳辐射和太阳活动的有关知识可以判断,该“喷嚏”应当是一次太阳活动,四个选项中,只有太阳耀斑爆发才符合题意,故答案选A;太阳爆炸、太阳辐射增强、太阳辐射减弱等现象都不属于太阳活动现象,故都不符合题意,BCD错误。故答案选A。

2 太阳发生耀斑,会产生强烈的高能带电粒子,这些高能带电粒子闯入地球,会干扰地球高空的电离层,影响无线电短波通讯;闯入地磁场,产生磁暴,信鸽会迷失方向,指南针会失灵;故ABC都与太阳活动有关,而地球公转速度的快慢与地球和太阳的距离有关,而与太阳活动无关,故D正确。

【题目】B

My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.

Then I started developing a problem with the set that involved static(静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

【1】 Why did the author say he was fooled into buying the TV set?

A. He got an older model than he had expected.

B. He couldn’t return it when it was broken.

C. He could have bought it at a lower price.

D. He failed to find any movie shows on it.

【2】Which of the following can best replace the phrase "signed off" in Paragraph 1?

A. ended all their programs B. provided fewer channels

C. changed to commercials D. showed all-night movies

【3】How did the author finally get his TV set working again?

A. By shaking and hitting it. B. By turning it on and off.

C. By switching channels. D. By having it repaired.

【4】How does the author sound when telling the story?

A. Curious. B. Anxious.

C. Cautious. D. Humorous.
