Reading is an experience quite different from watching TV;there are pictures____in your mind instead of before your eyes.
A.to form
B.form
C.forming
D.having formed
能分别解释下四个选项吗?这个句子好糊涂!
还有!分号有连词的作用吗?

Answer 1

Reading is an experience quite different from watching TV;there are pictures____in your mind instead of before your eyes.
A. to form
B. form
C. forming
D. having formed
==>选C.
结构：
there are pictures 【[forming in your mind] instead of [before your eyes]】. 上面黑体的方括号内的内容整个是个状语,补充说明是什么样的pictures,已经有谓语了,必须用非谓语形式,排除B.然后三种非谓语形式：to form,forming,having formed分别表示将来时态/一般时态/完成时态,这里是陈述事实,用一般时态.
