语法与词汇
The symbols of mathematics ______we are most familiar are the signs of addition, subtraction, multiplication, division and equality.
【正确答案】
C
【答案解析】该题测试词组的用法和句前带介词的从句用法。本题be familiar with词组中的介词with移到which引导的we are most familiar从句前。familiar之后既能接with,也能接to。familiar with指人对某人或事物熟悉,主语是有生命的名词;familiar to指某件事情对某人来讲熟悉,主语是无生命的名词。既然从句的主语是we,所以必须用with。译文:我们最为熟悉的数学符号就是加、减、乘、除和等号。
