【题目】At our factory there are a few machines similar to _______ described in this magazine.
A.thatB.thoseC.theseD.what
在线课程【答案】B
【解析】
考查代词。句意：我们工厂的有些机器和杂志上描述的相似。A. that那个；B. those那些；C. these这些；D. what什么。根据句意可知，所选词是用来代替上文提到的a few machines，且其后有后置定语described in this magazine修饰，由此可知，此处属于同类中的特指，machines为复数名词故应用those。故选B。
