北美大讲堂 | ACT真题解析第67期：最 新ACT文法考了什么？

　　本期专栏新航道南京act培训班小编将解析2021年6月ACT文法Passage 1中的部分题型，带大家一览最 新考题。

　　1.句子结构题

　　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)题：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：问题NOT be acceptable提示考生选错误选项，A从属子句、C破折号解释说明、D冒号解释说明都能作为独立句子的补充成分，B分号要求其后必须为独立句子，不符合原文，答案选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)题：F. NO CHANGE

　　G. reality. When three

　　H. reality, three

　　J. reality three

　　解析：原文显示为2个独立句子，其间用句号分隔。G选项导致从属子句When…独立，H选项导致run-on sentence错误，J选项也缺失了标点及连词，答案选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)题：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：分析句子核心为workers used tools to install the mirrors，such as给出例子，只有两种写法：such as …作为非必要修饰加双逗号或作为必要修饰不加标点，则可以迅速排除BCD，选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)题：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出现的时候，需要辨析哪些内容在并列，第 一个and并列的是动词controlled and monitored，动词并列共用主语不需要逗号，第二个and并列的是介词短语in Rjukan and on the mountain，也不需要标点隔开，一次你答案选J。

　　2.逻辑主语题

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

　　第(2)题：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：下划线标注了整个主句，考生能依赖的就是after doing短语了，现在分词短语前置时，考点是moving主动态搭配哪个主语逻辑合理，F为winter gloom冬季阴霾，G为it它，H为artist艺术家，J为gloom阴霾，能主动发出move移动的动作的只用H“人”。

　　3.句子连接题

　　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)题：F. NO CHANGE

　　G. but

　　H. yet

　　J. and

　　解析：选择恰当的连词需要理解前后句的含义，前一句为“他了解到，1913年，当地的簿记员Oscar Kittelsen曾提议为同样的目的竖立镜子”，后一句为“该镇的创始人Sam Eyde曾考虑过这个想法”，前后为并列关系选J。EGH都有转折的含义。

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

　　第(7)题：A. NO CHANGE

　　B. mountain because

　　C. mountain and

　　D. mountain,

　　解析：首先排除A(moreover不是连词)和D(没有连词导致run-on sentence错误)，其次考虑前后句是因果还是并列关系，前句为“直升机将重型设备运上山”，后句为“没有道路通往悬崖边的施工现场”，加上because后句意为“直升机将重型设备运上山，因为没有道路通向悬崖边的施工现场”，因果关系更为合理，选B。
