分析 你想知道地球水域里有什么嗎?來自五十三個不同國家的大約300名科學(xué)家對同樣的事情感到疑惑.有史以來第一次,科學(xué)家們正試圖計算生活在水下的魚、動物和植物有多少種.每個人都知道海洋覆蓋了地球表面的百分之七十.這項研究開始于2000,預(yù)計到2013年結(jié)束,耗資10億美元.到目前為止,在海洋中科學(xué)家們已經(jīng)獲得了超過15000種魚類和約有200000種動植物.他們希望在不久的將來至少能找到另外5000種魚類.
科學(xué)家認(rèn)為到目前為止,他們所發(fā)現(xiàn)的動植物僅占水下世界生命總數(shù)的10%.這意味著他們到2013年為止可能還會發(fā)現(xiàn)動植物近200萬種."我們的目標(biāo)是到2013年為止,像現(xiàn)在我們知道的陸地上的生命一樣盡可能多地了解海洋中的生命."一位正在從事這個項目的女科學(xué)家說.
新發(fā)現(xiàn)的動物或植物并不都是新的物種.他們中的許多之前已經(jīng)被發(fā)現(xiàn)過,只是從來沒有被記錄過.科學(xué)家們擔(dān)心,由于人類的原因,生活在海洋中的物種越來越少了.他們希望他們的研究和報告將幫助人們了解人類活動,如捕魚和農(nóng)業(yè),正在影響海洋.
解答 72.wondering. 考查動詞的用法及語境理解.根據(jù)上文Do you want to know what lives in the Earth's waters,可知你想知道地球水域里有什么嗎,而這里是說來自五十三個不同國家的大約300名科學(xué)家對同樣的事情感到疑惑,他們也想知道,所以這里用wonder,想知道,這里前面有are,時態(tài)應(yīng)該是現(xiàn)在進(jìn)行時,故填wondering.
73.many. 考查形容詞的用法及語境理解.根據(jù)scientists are trying to count,這里count是數(shù)數(shù)的意思,所以下面表示的應(yīng)該是數(shù)量,而提問數(shù)量應(yīng)該用how many表示多少,故填many.
74.surface.考查名詞的用法及語境理解.根據(jù)題干Everyone knows that oceans cover seventy per cent of the Earth's,眾所周知,海洋面積占了地球表面的百分之七十,根據(jù)首字母s,可知這里填寫surface,表面.故填surface.
75.end.考查動詞的用法及語境理解.根據(jù)The study began in 2000,可知這項研究開始于2000年,所以后面說的是到2013年結(jié)束,根據(jù)首字母e及語境,可知句子應(yīng)該填end,動詞,結(jié)束.故填end.
76.least.考查形容詞的用法及語境理解.根據(jù)They expect to find at--another 5,000 species of fish in the near future,可知他們希望在不久的將來至少能找到另外5000種魚類.這里考查短語at least至少,故填least.
77.that.考查連詞的用法及語境理解.根據(jù)Scientists believe--the animals and plants they've found so far represent just 10% of the world's total underwater--.可知科學(xué)家認(rèn)為到目前為止,他們所發(fā)現(xiàn)的動植物僅占水下世界生命總數(shù)的10%.這里believe后面跟的是一個賓語從句,這里句子不缺少任何成分,所以這里用that引導(dǎo).故填that.
78.population.考查名詞的用法及語境理解.根據(jù)Scientists believe--the animals and plants they've found so far represent just 10% of the world's total underwater--.可知科學(xué)家認(rèn)為到目前為止,他們所發(fā)現(xiàn)的動植物僅占水下世界生命總數(shù)的10%,這里動植物都是有生命,根據(jù)首字母p,可知這里用population,表示生物種群.故填population.
79.life.考查名詞的用法及語境理解.根據(jù)下文as we know about life on land now,可知像現(xiàn)在我們知道的陸地上的生命一樣,前面說的是海洋中的生命,根據(jù)首字母l及語境,可知這里填life.故填life.
80.a(chǎn)ll.考查形容詞的用法及語境理解.根據(jù)下文Many of them have already been discovered before and just never been recorded.可知他們中的許多之前已經(jīng)被發(fā)現(xiàn)過,只是從來沒有被記錄過,從這里可以推知新發(fā)現(xiàn)的動物或植物并不都是新的物種,根據(jù)首字母a及語境,可知這里用all,表示所有的,全部的,故填all.
81.worried.考查形容詞的用法及語境理解.根據(jù)題干the variety (多樣化) of species living in the ocean is becoming less because of humans.可知由于人類的原因,生活在海洋中的物種越來越少了,所以科學(xué)家們很擔(dān)心,根據(jù)首字母w及語境,可知這里用形容詞worried,擔(dān)心的,be worried about為…擔(dān)心.故填worried.
點(diǎn)評 此篇為英語閱讀填空.做題時先讀一遍題,不要看選項,盡量弄懂在講什么; 第二遍的時候,開始試著填,確定好詞性及詞意,注意利用固定搭配等輔助做題,其中聯(lián)系上下文是做好此類題的關(guān)鍵所在.第三遍根據(jù)所填的詞匯復(fù)讀文章,看前后是否連貫通順,是否符合邏輯,查漏補(bǔ)缺,完成校正.
