答案以及解析1．

due

to

bad

weather【詳解】考查介詞短語(yǔ)。句意：由于天氣惡劣，濱海馬路封閉?！坝捎凇睘閐ueto，“惡劣的天氣”為badweather。故填①due②to③bad④weather。2．

due

to

chance【詳解】考查固定短語(yǔ)和名詞。依據(jù)句意可知，空格處涉及固定短語(yǔ)“dueto”，意為“由于，因?yàn)椤?，“chance”意為“意外”，為不行數(shù)名詞，“duetochance”表示“純屬意外”。故填duetochance。3．

to

reduce

fuel

consumption【詳解】考查不定式和名詞。表示“降低”用reduce，此處應(yīng)用其不定式形式作目的狀語(yǔ)，表示“油耗”用fuelconsumption，作賓語(yǔ)。故填to；reduce；fuel；consumption。4．dueto##asaresultof##becauseof##owingto##onaccountof##resultingfrom【詳解】考查固定短語(yǔ)。句意：很多海鳥因石油泄漏而死亡。依據(jù)漢語(yǔ)提示，可以用介詞短語(yǔ)dueto/asaresultof/becauseof/owingto/onaccountof來(lái)表示“因?yàn)椤?。?dòng)詞短語(yǔ)resultfrom后面也加緣由，譯為“起因于”，此處須要用現(xiàn)在分詞作狀語(yǔ)，即resultingfrom。故答案為dueto/asaresultof/becauseof/owingto/onaccountof/resultingfrom。5．isbeingprepared【詳解】考查現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)。依據(jù)“正在”可知，此處應(yīng)用現(xiàn)在進(jìn)行時(shí)態(tài)。表示“打算”應(yīng)用動(dòng)詞prepare，主語(yǔ)ahotelroom與prepare構(gòu)成被動(dòng)關(guān)系，故用現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)，主語(yǔ)是單數(shù)。故填isbeingprepared。6．

is

being

made【詳解】考查時(shí)態(tài)語(yǔ)態(tài)。依據(jù)句意可知，本句為現(xiàn)在進(jìn)行時(shí)，主語(yǔ)asecretplan與謂語(yǔ)make為被動(dòng)關(guān)系，所以本句為現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)。故填isbeingmade。7．

are

being

built【詳解】考查動(dòng)詞、時(shí)態(tài)和語(yǔ)態(tài)。表示“修建”用build；主語(yǔ)Severalnewlines是復(fù)數(shù)形式，且與謂語(yǔ)之間是被動(dòng)關(guān)系，應(yīng)用被動(dòng)語(yǔ)態(tài)，謂語(yǔ)應(yīng)用復(fù)數(shù)形式；本題表述的是路途正在被修建，應(yīng)用現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)，即主語(yǔ)+am/is/are+being+過去分詞結(jié)構(gòu)；故填①are②being③built。8．duetothebadweather【詳解】考查短語(yǔ)。表示“由于”的短語(yǔ)為dueto；表示“天氣”的英文為weather；表示“不好”的英文為bad，“天氣不好”為thebadweather。故答案為duetothebadweather。9．Duetothegrowingpopularity【詳解】考查介詞短語(yǔ)。依據(jù)漢語(yǔ)提示設(shè)空處應(yīng)當(dāng)是用介詞短語(yǔ)作狀語(yǔ)。依據(jù)漢語(yǔ)提示，表示“因?yàn)椤睉?yīng)用dueto；表示“越來(lái)越受歡迎”應(yīng)用growingpopularity，其中g(shù)rowing為形容詞，意為“不斷增長(zhǎng)的”，popularity為不行數(shù)名詞意為“歡迎，流行”。同時(shí)該空置于句首，開頭單詞首字母應(yīng)當(dāng)大寫。故填Duetothegrowingpopularity。10．

being

treated

for【詳解】考查現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)。分析句子可知，空格處是該句子的謂語(yǔ)部分；依據(jù)漢語(yǔ)提示，“因……接受治療”翻譯為treat...for.
