Question

英语语法求救

He waits to get the same ten-speed-bicycle _______ is shown on TV
A , which B as
应该是as吧 ？
麻烦解释下

Answer 1

没错，答案是as.

语法规定：如果先行词被so/such/as/the same等修饰时，其后定语从句的关系代词一般使用as。
另：先行词为the same修饰时，也可以用that作为关系代词引导定语从句，但是和as有所区别。
that为原物，而as只是类似之物。
如：He bought the same car as I bought last week. 他买了一辆和我上周买的一模一样的汽车。
This is the same bike that I lost yesterday. 这就是我昨天丢的那辆自行车。

关系代词as代替先行词ten-speed bicycle，在定语从句中充当主语。

Answer 2

which
定语从句，从句中缺少主语，用that或 which
He waits to get the same ten-speed-bicycle ( _______ is shown on TV) 缺少主语

Answer 3

用as
the same as 固定句型
