题目内容
【题目】阅读下面材料，回答问题。
根据我国“风云”二号卫星的实时监测，2001年3月28日17时40分至22分，太阳连续爆发6起中等强度的耀斑，其中19时40分左右和20时20分左右的太阳耀斑持续时间近1个小时。29日17时50分左右，太阳又爆发一次强烈的耀斑，持续时间约1个小时，耀斑喷射的高能带电粒子流——“太阳风暴”几个小时就可抵达近地空间。
本次太阳峰年自1996年8月拉开“序幕”，1999年3月进入极盛期。从理论上说，目前太阳活动已逐渐走下坡路了。但它似乎并不服气，仍不时给地球通信、卫星、电力一点“颜色”看，而4月3日爆发的太阳X射线耀斑强度更是25年来之最。
本次太阳峰年有些特别，属于极盛期相对平静，下降期却“高潮迭起”。对照前两个太阳峰年活动，专家认为这种现象还是正常的。
（1）“太阳风暴”对地球的重大影响是（ ）
A．给予地球特别多的能量
B．使地球的温度升高很多
C．使地球的降水增加很多
D．会使地球紫外线的辐射量增多
（2）“耀斑”出现在太阳大气的哪个部位（ ）
A．太阳核部 B．光球层 C．色球层 D．日冕层
（3）根据太阳活动的周期，本次太阳峰年要真正滑入“谷底”，即太阳活动极小年的时间大约是（ ）
A．2007年前后 B．2004年前后
C．2001年前后 D．2012年前后
（4）文中“仍不时给地球通信、卫星、电力一点“颜色”看主要是指给地球及人类带来影响有
; ; （任填三点）
【答案】(1) D (2)C (3)A
(4)干扰高空电离层，影响无线电短波通信；扰乱地球磁场，引发磁暴现象；与两极稀薄大气摩擦，产生美丽的极光；造成气候的异常；地球上许多自然灾害的发生都与太阳活动有关，如地震、水旱灾害等（任三点得6分）
【解析】
试题分析：
（1）太阳会在太阳黑子活动的高峰时产生太阳风暴，由于太阳风中的气团主要内容是带电等离子体，并以每小时150万到300万公里的速度闯入太空，因此它会对地球的空间环境产生巨大的冲击，阳风暴爆发时,将影响通讯、威胁卫星、破坏臭氧层，对人体的健康也会造成一定影响。
（2）太阳耀斑是一种最剧烈的太阳活动，一般认为发生在色球层中，所以也叫“色球爆发”。
（3）太阳黑子是太阳活动的重要标志之一，太阳黑子的平均周期是11年。
（4）太阳活动干扰高空电离层，影响无线电短波通信，扰乱地球磁场，引发磁暴现象，与两极稀薄大气摩擦，产生美丽的极光。

Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored(监控) in different ways, researchers are discovering new rules. By tracking people’s e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.
＂The ‘if it bleeds’ rule works for mass media,＂ says Jonah Berger, a scholar at the University of Pennsylvania. ＂They want your eyeballs and don’t care how you’re feeling. But when you share a story with your friends, you care a lot more how they react. You don’t want them to think of you as a Debbie Downer.＂
Researchers analyzing word-of-mouth communication — e-mails, Web posts and reviews, face-to-face conversations — found that it tended to be more positive than negative(消极的), but that didn’t necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times’ website. He and a Penn colleague analyzed the ＂most e-mailed＂ list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times’ readers and made them want to share this positive feeling with others.
Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused(激发) one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, ＂Contagious: Why Things Catch On.＂
