问题描述：
The financial crisis(危机) that originated(源于)on Wall Street(华尔街) swept
the
world,thus________large numbers of workers jobless.
A．leaving B．to leave C．left D．have left
thus 不是连词吗?为什么还用非谓语?
答
这题主要考察非谓语动词的用法.动词leave与其逻辑主语the financial crisis 之间是主谓关系,所以用leaving作结果状语,相当于which left.
所以选A,thus这个词作为连词一般都是放在句首单独引导一个完整的句子,所以你可以把后半句改为Thus,the fiancial crisis left large.
给你举一个其他的例子：
Agriculture has developed rapidly,thus providing light industry with ample raw materials.
农业迅速发展,从而为轻工业提供了充足的原料.
