本期專欄將解析2021年6月ACT文法Passage 1中的部分題型，帶大家一覽最新考題。

　　1.句子結(jié)構(gòu)題

　　原文：It’s winter, and the sun’s rays no longer shine directly on Rjukan (1), a small town in south-central Norway.

　　第(1)題：Which of the following alternatives to the underlined portion would NOT be acceptable?

　　A. Rjukan, which is

　　B. Rjukan;

　　C. Rjukan—

　　D. Rjukan:

　　解析：問題NOT be acceptable提示考生選錯誤選項，A從屬子句、C破折號解釋說明、D冒號解釋說明都能作為獨立句子的補充成分，B分號要求其后必須為獨立句子，不符合原文，答案選B。

　　原文：One hundred years later, Andersen made the mirrors a reality. Three (6) 550-square-foot mirrors were airlifted to the top of a ridge 1,475 feet above Rjukan.

　　第(6)題：F. NO CHANGE

　　G. reality. When three

　　H. reality, three

　　J. reality three

　　解析：原文顯示為2個獨立句子，其間用句號分隔。G選項導(dǎo)致從屬子句When…獨立，H選項導(dǎo)致run-on sentence錯誤，J選項也缺失了標(biāo)點及連詞，答案選F。

　　原文：Since a crane would have been too heavy for helicopters to lift, workers used tools such as thirty-foot wooden tripods (9) to install the mirrors.

　　第(9)題：A. NO CHANGE

　　B. tools, such as thirty-foot, wooden, tripods

　　C. tools such as thirty-foot wooden tripods,

　　D. tools, such as thirty-foot wooden tripods

　　解析：分析句子核心為workers used tools to install the mirrors，such as給出例子，只有兩種寫法：such as …作為非必要修飾加雙逗號或作為必要修飾不加標(biāo)點，則可以迅速排除BCD，選A。

　　原文：They’re controlled wirelessly by a company in Germany, and monitored, in Rjukan and (12) on the mountain via webcam.

　　第(12)題：F. NO CHANGE

　　G. Germany and, monitored in Rjukan, and

　　H. Germany and monitored in Rjukan, and,

　　J. Germany and monitored in Rjukan and

　　解析：有and出現(xiàn)的時候，需要辨析哪些內(nèi)容在并列，第一個and并列的是動詞controlled and monitored，動詞并列共用主語不需要逗號，第二個and并列的是介詞短語in Rjukan and on the mountain，也不需要標(biāo)點隔開，一次你答案選J。

　　2.邏輯主語題

　　原文：After moving to Rjukan in 2001, the prolonged winter gloom alarmed artist Martin Andersen (2).

　　第(2)題：F. NO CHANGE

　　G. it was the prolonged winter gloom that alarmed artist Martin Andersen.

　　H. artist Martin Andersen was alarmed by the prolonged winter gloom.

　　J. the gloom that lasted all winter was alarming for artist Martin Andersen.

　　解析：下劃線標(biāo)注了整個主句，考生能依賴的就是after doing短語了，現(xiàn)在分詞短語前置時，考點是moving主動態(tài)搭配哪個主語邏輯合理，F(xiàn)為winter gloom冬季陰霾，G為it它，H為artist藝術(shù)家，J為gloom陰霾，能主動發(fā)出move移動的動作的只用H“人”。

　　3.句子連接題

　　原文：He learned that in 1913 local bookkeeper Oscar Kittelsen had proposed erecting mirrors for the same purpose, and instead (4) Sam Eyde, the town’s founder, had considered the idea.

　　第(4)題：F. NO CHANGE

　　G. but

　　H. yet

　　J. and

　　解析：選擇恰當(dāng)?shù)倪B詞需要理解前后句的含義，前一句為“他了解到，1913年，當(dāng)?shù)氐牟居泦TOscar Kittelsen曾提議為同樣的目的豎立鏡子”，后一句為“該鎮(zhèn)的創(chuàng)始人Sam Eyde曾考慮過這個想法”，前后為并列關(guān)系選J。EGH都有轉(zhuǎn)折的含義。

　　原文：Helicopters carried the heavy equipment up the mountain, moreover, (7) no roads led to the cliffside construction site.

　　第(7)題：A. NO CHANGE

　　B. mountain because

　　C. mountain and

　　D. mountain,

　　解析：首先排除A(moreover不是連詞)和D(沒有連詞導(dǎo)致run-on sentence錯誤)，其次考慮前后句是因果還是并列關(guān)系，前句為“直升機將重型設(shè)備運上山”，后句為“沒有道路通往懸崖邊的施工現(xiàn)場”，加上because后句意為“直升機將重型設(shè)備運上山，因為沒有道路通向懸崖邊的施工現(xiàn)場”，因果關(guān)系更為合理，選B。

　　小結(jié)：本期內(nèi)容暫時告一段落，更多關(guān)于ACT文法的其他考題和解題步驟，我們下期再見!
