单选题
In the southwestern part of the United States ______ built in the last century.
【正确答案】
B
【答案解析】[解析] 在以be做谓语的句子中，如果表示地点的状语放在句首，则往往用倒装句。in the southwestern part…为地点状语，are…mining towns是倒装语序。这里用倒装语序更合适，因为towns后面还有定语built in the last century修饰。又如在《大学英语》第一册第三课The Present中有这样一个句子：Folded in the card was a piece of paper. Written on the card was a message under the printed Happy Birthday.这个句子可以改写为本题中的句型：In the card was folded a piece of paper. On the card was written a message under the printed Happy Birthday.
