Was it through Mary _____ was working at a high school ____ you got to know Tom? A．who; who B．that; which C．who; that D．who; which

Answer 1

C

试题分析：考查定语从句和强调句型。本题第一空是定语从句，先行词是Mary，关系代词who指代先行词在句中做主语。第二空中的that与it was构成强调句型。句意：正是通过在高中读书的Mary，你才认识Tom的吗？第一空可以使用that/who，但是为了避免和后面的that重复，所以使用了who。故C正确。 点评：定语从句的关键在于分析句子结构，定语从句中如果既不缺主语，也不缺宾语和表语，就要考虑是否用关系副词或whose作定语，意为“谁的”。至于如何判断缺不缺主或是宾语，尤其是缺宾语的情况，要将先行词带到定从中谓语动词之后看是否符合逻辑搭配，如符合则缺宾语，如不符合就不缺。同时强调句型在高考中每年必出，关键是要会判断，平时练习时要有这个意识。it is /was+被强调部分+that/who+…判断方法是去掉it is /was  that/who句子不缺成分，即为强调句型。
