有读者问： 在《薄冰英语语法》中有一例句：
(1)There's much which will be unpleasing to the English reader.
不定代词much, little按说其后的关系代词应用that，但这里much之后却用了which，不知是何缘故？
much作为不定代词，其后的关系代词的确多用that，如：
(2)I owe her much that I hold sweetest and most precious.
(3)It was painful to hear so much that was pretty and undefended and natural assigned to a vulgar place among the categories of disorder.
(4)Though more courses were offered during the sixties, there is little evidence that education improved and much that it declined.
但和许多其他不定代词（包括复合不定代词something, anything等）一样，much之后亦可接关系代词which，只是情况较少而已，上述句（1）即是一例，再如：
(5)It seems that while the Chinese method of teaching elementary school children is not perfect （whose is?）,there is much which school systems such as those in the United States could learn from it.
little作为不定代词，和much一样，也常后接关系代词that，但有时亦可后接which，如：
(6)I have introduced little which can be termed modern.
这里我们愿意引述一位英语语法大师的话，他说有些学者从who和which会想到拉丁语的代词，从而认为它们较通俗的that要高雅一些。这也就是某些人喜用which的缘故吧。对于中国学生来说，还是以用that为妥。
