学员疑问:expand和extent在应用上有啥区别?
老师解答:expand: to become greater in size, number or importance; to make sth greater in size, number or importance 扩大,增加,增强(尺码、数量或重要性)表示抽象事物如市场的扩大延伸
例句:Metals expand when they are heated. 金属受热会膨胀。
extend: to make sth. longer or larger 使伸长;延伸;扩展,表述具体事物,如管道设施架设延伸
例句:You can't see the full extent of the beach from here. 从这儿看不到海滩全貌。
点评分析:区分英语同义词,重点是看英英释义和例句,了解使用范围,可以通过权威的牛津词典,韦氏词典里面的例句来做具体的区分。当然还可以适当做一做词汇题加以巩固。
