选项
A、entire
B、total
C、complete
D、complex
答案
A
解析
词义搭配。entire与whole在许多情况下可以通用。例如:The people’s government has the support of the entire(=whole)population.(人民政府得到全民的支持)。但是,entire可以修饰抽象名词,whole有时就不能。例如:I am in entire ignorance of what he did.(我全然不知他做了些什么)。total与entire不同,total有较强的数量计算意味。例如:The total sum of the expenditure is twelve dollars and fifty-seven cents.(开支总数是12美元57美分)。complete完全的,不缺乏什么的。例如;Now that the missing volume has been found,the series is complete.(丢的那卷找到了,因此这部书又完整了)。complex联合的,复合的。例如:a complex system/network。
