题目内容
5.One of the most important questions they had to consider was of public health( )A. | what | B. | this | C. | that | D. | which |
分析 他们必须考虑的问题之一是公众的健康问题.
解答 答案:C
句中was后接的是名词短语,不是从句,不能用连词,可排除A和D;句意指代的是前面的one question,且后接介词of,要用that来指代,相当于the one.故选C.
点评 指示代词是表示指示概念的代词,即用来指示或标识人或事物的代词.指示代词与定冠词和人称代词一样,都具有指定的含义,用来起指示作用或用来代替前面已提到过的名词.指示代词分单数(this/that)和复数(these/those)两种形式,既可作限定词又可做代词.
