Is this the only way ____ the station?
选A. leading to
which leads to 中,问题在于关系代词which.因为先行词way有only修饰,不可以用which,能用that.
即:
Is this the only way that leads to the station?
that 在从句中作主语,省略之后,句子就变成:
Is this the only way leading to the station? (其中,leading是现在分词,作定语)
【语法贴士】
限定性定语从句中,如果先行词被the only, the very, the same, the last 等修饰,关系代词用that,不能用which.
