【題目】Directions:Complete the following passage by using the words in the box. Each word can be used only once. Note that there is one word more than you need.

A drop in the sun’s radiation can cause cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries 【1】 for storms.

Scientists have known for a long time that the sun has an 11-year cycle during which radiation from the sun reaches a(n) 【2】 then falls. But detecting a clear link of the cycle to the weather has proved much 【3】.

“Our research notices a link between solar activities and regional winter climate,” lead author Sarah Ineson of the UK Met Office told the reporters in an email.

Her team focused on the data from the recent minimum solar radiation period during 2008-10, which was a(n) 【4】 calm period for the sun but at the same time, 【5】 winters in the U.S and Europe were recorded which brought troubles to many businesses and made people’s lives difficult.

The researchers found that a reduction in radiation from the sun can affect wind patterns, 【6】 cold winters.

“While radiation levels won’t tell us what the day-to-day weather will be, they provide the exciting 【7】 of improved prediction for winter conditions for months and even years ahead. These predictions play an important role in long-term weather planning,” Ineson said.

Ineson’s team used the data in a complex computer to 【8】 long-term weather patterns. It successfully reproduced what scientists had observed happening in the upper atmosphere during changes in solar radiation. More study was needed, though. The key 【9】 in the experiment lay in the satellite data used, because it spans (跨度) only a few years.” So there are still questions concerning whether the current research results are accurate and whether they can be 【10】 to other solar cycles,” she said.

這是一篇說(shuō)明文�？茖W(xué)家們發(fā)現(xiàn)，太陽(yáng)輻射的降低會(huì)導(dǎo)致北美和歐洲寒冷的冬天，這個(gè)發(fā)現(xiàn)能幫助預(yù)測(cè)長(zhǎng)遠(yuǎn)的天氣以及幫助國(guó)家提前預(yù)防暴風(fēng)雨。文章還詳細(xì)論述了科學(xué)家們研究使用的數(shù)據(jù)、方法以及研究的缺陷。

【1】考查不定式做賓補(bǔ)。句意：這項(xiàng)發(fā)現(xiàn)能改善長(zhǎng)期的天氣預(yù)測(cè)并幫助國(guó)家為暴風(fēng)雨做好準(zhǔn)備。“幫……做某事”可翻譯為“help sb. do sth.”，應(yīng)使用不帶to的不定式做賓補(bǔ)�！�prepare for…”譯為“為……做好準(zhǔn)備”。故選J。

【2】考查名詞。句意：長(zhǎng)久以來(lái)，科學(xué)家們已經(jīng)知道，太陽(yáng)有一個(gè)11年的周期，在這個(gè)周期內(nèi)太陽(yáng)輻射達(dá)到頂峰再降低�？崭袂盀椴欢ü谠~，空格后沒(méi)有名詞，故空格處應(yīng)填入名詞。由“then falls”可知，空格處應(yīng)該填入“最高點(diǎn)”�！�peak”意為“最高點(diǎn)；頂點(diǎn)”，符合句意。故選A。

【3】考查形容詞。句意：發(fā)現(xiàn)這個(gè)周期與天氣之間的明顯的關(guān)系是比較復(fù)雜的。這句話與上句中“have known for a long time”形成對(duì)比關(guān)系，體現(xiàn)雖然早就知道了太陽(yáng)周期，但是它與天氣之間的關(guān)系是非常復(fù)雜的�！�complicated”意為“難懂的，復(fù)雜的”，符合句意。故選H。

【4】考查副詞。句意：她的團(tuán)隊(duì)集中關(guān)注了最近的2008年至2010年之間太陽(yáng)輻射量最少的這段時(shí)期，這段時(shí)期內(nèi)太陽(yáng)異常的平靜但是同時(shí)，美國(guó)和歐洲嚴(yán)寒的冬季給商業(yè)和人們的生活帶來(lái)很大的麻煩和困難�？崭裉巻卧~修飾形容詞calm，應(yīng)用副詞形式。選項(xiàng)中只有unusually（不尋常的）是副詞，且符合句意。故選G。

【5】考查形容詞。句意同上。空格后為名詞的復(fù)數(shù)形式，所以空格處填形容詞。“intense winter”意為“嚴(yán)寒的冬季”，符合句意。故選C。

【6】考查分詞作狀語(yǔ)。句意：研究者發(fā)現(xiàn)太陽(yáng)輻射的降低能影響風(fēng)的模式，預(yù)示著寒冷的冬天。句子謂語(yǔ)動(dòng)詞為can affect，所以空格處應(yīng)填非謂語(yǔ)動(dòng)詞形式，表達(dá)自然而然的結(jié)果，所以用現(xiàn)在分詞表達(dá)自然而然的結(jié)果�！�indicating”意為“表明，暗示”，符合句意。故選D。

【7】考查名詞。句意：盡管輻射水平不能告訴我們每天的天氣狀況，但是它們能很好地預(yù)測(cè)幾個(gè)月或幾年內(nèi)的冬天的天氣狀況。空格位于定冠詞后，介詞前，所以應(yīng)用名詞形式�！�prospect”意為“前途，預(yù)期”，符合句意。故選B。

【8】考查動(dòng)詞。句意：伊尼森的團(tuán)隊(duì)在電腦中使用這些數(shù)據(jù)模仿了長(zhǎng)時(shí)期內(nèi)天氣類型�？崭裎挥诓欢ㄊ�to后，應(yīng)用動(dòng)詞原形�！�modle”意為“模仿、模擬”，符合句意。故選K。

【9】考查名詞。句意：試驗(yàn)最大的不確定性在于使用的衛(wèi)星數(shù)據(jù)，因?yàn)檫@些數(shù)據(jù)只是幾年的跨度。空格位于定冠詞后，實(shí)義動(dòng)詞前，應(yīng)用名詞形式。“uncertainty”意為“不確定的事物；不確定度”，符合句意。故選F。
