Many houses in the north are warm in winter because they are ______ so that the beat is not lost.
A．isolated
B．insulated
C．imparted
D．integrated请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：B
解析：形近易混词辨义。这四个选项都是动词形式，isolate表示“使孤立；使隔离”；insulate表示“使绝热；使绝缘”；impact意指“(常与on连用)对…施加影响”；integrate表示“使成整体；结合”。根据句意，北方的房子肯定是做了隔热处理，所以B)项符合题目要求。
