语法与词汇 1.Which of the following italicized parts does NOT serve as an appositive?

A、 Most students in our class, particularly David and Chris, are fond of Music.
B、 He always spoke so — slowly but energetically.
C、 The question whether to confess it or not troubled him.
D、 There is nothing to fear.

【正确答案】 D

【答案解析】句子成分。A项同位语David and Chris之前带引导词，以表示该同位语与它所说明的同位成分之间的关系，如especially，particularly，chiefly，mostly等表示突出某点；B项副词so的同位语可以由副词担任，或由起同样句法作用的介词词组担任；C项不定式结构做名词词组the question的同位语是起说明作用的。D项是修饰语。
