48.A
no sooner…… than一"……就……"前用倒装,后用正常语序
50.D
表示地点的状语放前面时,引起倒装,动词放在主语之前即可,不需再借助助动词,例如There comes the bus而不用there does come the bus；
lie“躺”的过去分词为lay
1.A 句型No sooner had sb. done than sb. did
2.D 地上躺着一条死蛇。 调整顺序理解A dead snake lay on the groud.
lie-lay-lain躺 lay-laid-laid下蛋 lie-lied-lied撒谎
A no sooner...than...是固定搭配，这里no sooner提前要用倒装。这个句型主句用过去完成时，从句用过去式。
D还是倒装，这里是lie的过去式lay，表示躺着一条蛇。laid是lay（放置，产卵）的过去式。
