child已充当了宾语，故从句中缺少状语，应使用关系副词where。
3．误：He paid the boy $15 for washing ten windows，most of them hadnt been cleaned for at least a year．
　　正：He paid the boy $15 for washing ten windows, most of which hadnt been cleaned for at least a year．
　　误：This is the boy with him he worked．
　　正：This is the boy(that／whom) he worked with。
　　正：This is the boy with whom he worked．
　　析：在定语从句中，如果介词及介词短语用在从句前，其后必须用关系代词which(指物)、whom(指人)。上面两误句中先行词windows(物)，the boy(人)应分别使用most of which和with whom。如果介词及介词短语用在从句句尾，应按普通定语从句对待。
