Question

The couple are spending their holiday on _____is described as one of the most beautiful islands.

A．that

B．what

C．which

D．where

Answer 1

B

试题分析：考查宾语从句。本题中的what is described as one of the most beautiful islands在句中作为介词On的宾语；what在这个宾语从句中做主语。句意：这对夫妻正在被称为世界上最美丽的岛屿上度假。故B正确。That和where在句中不能做主语。Which是指特定范围之内的某一个。
点评：名词性从句的考查集中在引导词的选择上，连接词that, whether, if在句中不充当任何成分，只起连接作用；连接代词who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主语，宾语，表语和定语；连接副词when, why, where, how，在句中做状语。应从上下句的句法关系着手分析，切不可‘望句形生答案’总的来说，考生在解答此类型时，可用排除法或造句法，造句法就是仿造原句的语法功能仿造出一个易懂易理解的句子，帮助判断。
