(单选题)

Nowadays, people like HUAWEI phones better, and about of them are adults.

A.the number of; four-fifths

B.a number of; four-fifth

C.a number of; four-fifths

D.the number of; four-five

参考答案：C

参考解析：

考查介词短语辨析和数词。句意：如今，许多人更喜欢华为手机，其中约五分之四是成年人。the number of意为“……的数量”，充当主语，谓语动词使用单数；a number of意为“许多，大量的”，修饰可数名词复数，充当主语时，谓语动词使用复数；根据谓语动词like可知第一个空应填a number of。分数表达法：基数词做分子，序数词做分母，若分子大于1，分母用复数，“五分之四”是four-fifths，故第二个空应填four-fifths。故选C。
