问题描述:

Entering the office,I found the boos ___ at the desk,___ something on a piece of paper
a.sitting; wrote b.seated; writing
B

注意!!!!!!!!!!!!!!!seat只可以用seated,不可以用seating!!!
比如说某人坐着,只能说he seated himself.还可以用seat somebody,给某人找座。

第一个空格sitting和seated都可以,第二个空格只能填writing,是现在分词作伴随状语,修饰老板坐在桌边伴随的状态。

sitting
writing
find这个动词后面可以接原型,也可以接ing,前者表示发现动作的整个过程,后者只是看到部分

a.这是伴随动作.
