John plays football_________,if not better than ,David.

B.
as
well
as
John
plays
foot
ball
as
well
as,
if
not
better
than,
David.
如果John的football
玩得没David好，那就是跟他一样好。
如果没有后面那一句
John
plays
football
（A)
as
well.
意思就是
John
也玩
football.
John
plays
football
(C)
so
well.
意思是
John
的
football
玩得很好。
John
plays
football
(D)
so
well
as.....
so
well
as
不是一个明确的短语。
只有(B)
as
well
as
是正确。
因为在这里，John
被用来和David作比较。
"as
well
as"
意思就是
跟____一样好
