问题描述:

( ) the yard,I found it ( ) with lots of ( ) leaves.
A.Entering;covering;falling
B.Entered;covering;fallen
C.Entering;covered;fallen
D.Having entered;covered;falling
为什么选C?

这是句前后主语一致的句子也就是独立主格.
entering是主动的意思和i found中的主语是一致的,所以用的是现在分词,而后面的yard是被落叶覆盖的所以found后面用的被动语态,fallen leaves是固定搭配表示的是落叶.
