Answer 1

分析 這位科學(xué)家很匆忙．她必須在夜幕降臨之前去取些水進(jìn)行實(shí)驗(yàn)，她正在測(cè)試流進(jìn)海洋的河水．她的任務(wù)是查明在海灘附近的海水污染的原因．她提起了水，生氣地看著里面的垃圾．舊衣服，塑料袋，紙都在臟水里．"難道沒有人意識(shí)到他們?nèi)拥浇稚系乃�有東西都被沖進(jìn)河流嗎？它們又正好流入海洋．她大聲地說："要多少年才能使它（海水）重新干凈呢？"

解答 46．C 考查名詞用法．根據(jù)關(guān)鍵部分get some water for her…可知形容詞性物主代詞后應(yīng)該跟名詞；結(jié)合后句She was testing the water in the rivers that went into the ocean（ 她正在測(cè)試流進(jìn)海洋的河水）可推知此處應(yīng)是指取一些水做實(shí)驗(yàn)，結(jié)合選項(xiàng)故用名詞experiment實(shí)驗(yàn)．故選C
47．D 考查名詞用法．根據(jù)關(guān)鍵部分find out the cause of…可知of相當(dāng)于名詞所有格的功能，其后應(yīng)該跟名詞；結(jié)合后句She lifted out the water and looked angrily at the rubbish in it．（她提起了水，生氣地看著里面的垃圾）可知水被污染了，所以這里應(yīng)是指查明海水污染的原因，結(jié)合選項(xiàng)故用名詞pollution"污染"．故選D．
48．E 考查形容詞用法．根據(jù)Old clothers，…bags and pieces of paper were in the dirty water可知這些東西都是海水里的垃圾，結(jié)合bags可知前面缺少一個(gè)形容詞來修飾是什么樣的袋子，因?yàn)槭抢�圾，所以�?lián)想到白色污染塑料袋，結(jié)合選項(xiàng)應(yīng)用形容詞plastic"塑料的"．故選E
49．A 考查動(dòng)詞用法．根據(jù)"Don't people…that…可知that后引導(dǎo)賓語從句，故空處應(yīng)該為動(dòng)詞； 結(jié)合后面everything they throw onto the street gets washed into rivers？聯(lián)系前面可知此句為反意疑問句，表達(dá)肯定的意義；"他們?nèi)拥浇稚系乃�有東西都被沖刷進(jìn)河流"是客觀事實(shí)，所以此處應(yīng)是反問難道沒有意識(shí)到這一點(diǎn)嗎？結(jié)合選項(xiàng)應(yīng)該用動(dòng)詞realize"意識(shí)到"．故選A．

點(diǎn)評(píng) 此篇為記敘文的完型填空題．這是一篇有關(guān)環(huán)保的短文．文章比較短，涉及到的題目不多．做題時(shí)首先要了解被選詞的含義；然后在明白大意的基礎(chǔ)上，利用句子中的關(guān)鍵部分和前后的語境準(zhǔn)確判斷出詞性和詞義，從而填入正確意義和形式的單詞．
