A、they
B、which
C、there
D、that
【正确答案】：C
【题目解析】：第22题考察的是代词的选择和用法。 在句子"In addition to the standard varieties of English found in these areas, _______ are a great many regional and social varieties of the language as well as _______ levels of usage that are employed both in its spoken and written forms."中，第一个空格需要一个代词来引导后面的句子，并且这个代词需要指代前文提到的“English的标准方言”之外的那些内容。而“there”在这里作为一个引导词，表示存在，即“存在许多地区的和社会的方言”，因此选项C“there”是合适的。 第二个空格需要的是一个定语代词，用来修饰“levels of usage”。然而，由于该句已经有一个完整的从句结构“that are employed both in its spoken and written forms”，所以不需要额外的定语代词来修饰“levels of usage”。这里的“levels of usage”作为主语的一部分，直接跟在“as well as”后面，因此不需要额外的代词。 选项A“they”通常作为主语或宾语的代词，但在这个上下文中，它并没有明确的指代对象。选项B“which”通常用作定语从句的引导词，但在这里并不适用，因为句子结构并不需要定语从句。选项D“that”也可以用作定语从句的引导词，但同样在这个句子中并不适用。 综上所述，正确答案是C，即“there”。
