选择题
It took a long time for the connection between body temperature and illness ___________.
A．to make
B．to be made
C．making
D．being made
答案
答案：B
题目分析：根据句型It takes some time to do sth.可排除C和D项。由因为the connection between body temperature and illness和make之间为被动关系，故选B项。
点评：常见的只用动名词或不定式做主语的句型一定要掌握，需要使用时，直接拿过来就用。
