Question

【題目】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（太陽風(fēng) 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（太陽耀斑）: large explosions（爆炸）near the sun that can give off lots of energy. The strong energy can stop the satellite systems（衛(wèi)星系統(tǒng)）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.

【3】B

【4】C

【5】D

【解析】

本文是介紹太陽風(fēng)暴及其后果。

【1】細(xì)節(jié)理解題。根據(jù)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.” 可知選項(xiàng) B、C、D 均是太陽風(fēng)暴可能造成的后果，而A選項(xiàng)“地震”不是，故選A。

【2】細(xì)節(jié)理解題。根據(jù)關(guān)鍵詞“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：“太陽風(fēng)暴是由太陽耀斑造成的，（太陽風(fēng)暴）是在太陽附近的巨大的爆炸，它可以釋放出許多能量”，只有 C 選項(xiàng)符合對關(guān)鍵詞“solar flares”的解釋，故選C。

【3】推理判斷題。a:太陽耀斑釋放出許多能量。b:人們的電腦無法上網(wǎng)。c:產(chǎn)生太陽風(fēng)暴。d:衛(wèi)星系統(tǒng)癱瘓。根據(jù)文章第三段，事件發(fā)生的順序?yàn)?/span> a-c-d-b，故選 B。

【4】主旨大意題。根據(jù)文章最后一段可知太陽風(fēng)暴無法預(yù)測，因此 A錯誤；文章沒有指出任何能解決太陽風(fēng)暴造成后果的方法，因此 B 錯誤；文章沒有呼吁人們預(yù)防太陽風(fēng)暴發(fā)生，因此 D 錯誤；結(jié)合全文，可知文章是介紹太陽風(fēng)暴及其后果，故選 C。

【5】詞意猜測題。根據(jù)關(guān)鍵句“your mobile phone loses its signal”，“你的手機(jī)失去它的 _______”，句子the television has no programs, and you can’t get online you’re your computer. 可知，電視沒有節(jié)目，你不能用你的電腦上網(wǎng)。因此前面應(yīng)該是手機(jī)失去信號。故選 D。

詞義猜測題是閱讀理解中常見的一種題型，所猜測詞匯可以是生詞，也可以是熟詞新義，還可以是人稱代詞的指代內(nèi)容。詞義猜測題主要考查考生根據(jù)上下文推測詞義和語義的能力，突出考查對語境的分析和把握能力。常見的猜詞法有：(1)利用上下文語境。猜測任何詞義都離不開上下文，所以要借助上下文對需要猜測的詞或短語進(jìn)行合乎邏輯的推測。 (2)利用定義或解釋性的線索。閱讀文章中的有些生詞往往在其后會有對該詞進(jìn)行解釋說明的短語或句子，利用它們猜詞義較容易 (3)利用文章的邏輯關(guān)系答題。如并列、對比、因果、轉(zhuǎn)折關(guān)系等。這些邏輯關(guān)系往往通過一些相應(yīng)的詞或短語表達(dá)出來，如but, or, however, so, because等。(4)利用構(gòu)詞法知識答題。熟記一些前綴、后綴所表達(dá)的意思，不僅可以擴(kuò)大詞匯量，而且?guī)椭�我們猜測詞義。第5小題的詞義猜測題就是利用第1種解題方法。
