问题 The waste pipe is blocked; try ______ it out with hot water, or just call the plumber to do it.
选项 A、flushing
B、crushing
C、brushing
D、blushing
答案A
解析 形近易混词辨义。这四个选项的词性都是动词，其中flush表示“淹没，冲洗，使脸红，使齐平，使惊飞，使激动”，如：The river flushed the meadow．(河水淹没了草地。)crush是指“压碎；压坏；碾碎”，如：Huge hammers crush(up)the rocks．；brush表示“轻擦；轻触”，blush表示“脸红；赧颜”。根据句意，此处应该是冲刷管道，应该选择A)。
