这是一个主语从句与IF假设句的结合,分清其结构就好回答了.
1.“he was ill,I was expected to take his place”这是本句的主语,因为没有连接词,所以因加上关系代词“that”.
2.可根据“ he was ill,I was expected to take his place”与后文句意的联系,可判断这是个IF假设句,所以要用IF.
3.再因为THAT是整个句子的关系代词,而IF只是前半句中的一个词,所以THAT应在IF前面.
83.A
这是个主语从句与定语从句的结合句.但题点在定语从句上,所以就分析它吧.
其实这是个省略了的定语从句,其完整句子应是:
Those (who are)not wanting to go to the exhibition should inform the office.
就如:The man (who is) drinking there is my Chinese teacher.
