Question

【题目】Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your mobile phone loses its signa l, the television has no programs, and you can’t get online with your computer.

What has happened? These are just the types of problems a solar storm（太阳风 暴）might cause. You may not think of storms as putting our society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares（太阳耀斑）: large explosions（爆炸）near the sun that can give off lots of energy. The strong energy can stop the satellite systems（卫星系统）that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past few months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine’s Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

“Solar flare activity is going to be much worse than what we’ve seen in the past. We’re not talking about a few cities losing power, it could be half of the country, maybe more.” SolarStormWarning.com, a US website about space weather, warned.

Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

Answer 1

【答案】

【1】A

【2】C

【3】B

【4】C

【5】D

【解析】

本文是介绍太阳风暴及其后果。

【1】细节理解题。根据文章第一段“your mobile phone loses its signal”, “you can’t get online with your computer”, 以及文章第三段 “These storms can even cause the power to go out for weeks or months.” 可知选项 B、C、D 均是太阳风暴可能造成的后果，而A选项“地震”不是，故选A。

【2】细节理解题。根据关键词“solar flares”定位到文章第三段“A solar storm is caused by solar flares: large explosions near the sun that can give off lots of energy.”可知：“太阳风暴是由太阳耀斑造成的，（太阳风暴）是在太阳附近的巨大的爆炸，它可以释放出许多能量”，只有 C 选项符合对关键词“solar flares”的解释，故选C。

【3】推理判断题。a:太阳耀斑释放出许多能量。b:人们的电脑无法上网。c:产生太阳风暴。d:卫星系统瘫痪。根据文章第三段，事件发生的顺序为 a-c-d-b，故选 B。

【4】主旨大意题。根据文章最后一段可知太阳风暴无法预测，因此 A错误；文章没有指出任何能解决太阳风暴造成后果的方法，因此 B 错误；文章没有呼吁人们预防太阳风暴发生，因此 D 错误；结合全文，可知文章是介绍太阳风暴及其后果，故选 C。

【5】词意猜测题。根据关键句“your mobile phone loses its signal”，“你的手机失去它的 _______”，句子the television has no programs, and you can’t get online you’re your computer. 可知，电视没有节目，你不能用你的电脑上网。因此前面应该是手机失去信号。故选 D。

词义猜测题是阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。常见的猜词法有：(1)利用上下文语境。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。 (2)利用定义或解释性的线索。阅读文章中的有些生词往往在其后会有对该词进行解释说明的短语或句子，利用它们猜词义较容易 (3)利用文章的逻辑关系答题。如并列、对比、因果、转折关系等。这些逻辑关系往往通过一些相应的词或短语表达出来，如but, or, however, so, because等。(4)利用构词法知识答题。熟记一些前缀、后缀所表达的意思，不仅可以扩大词汇量，而且帮助我们猜测词义。第5小题的词义猜测题就是利用第1种解题方法。
