This is the best film____I have ever seen?填that or what
这是一个定语从句,应填that,或是把that省掉,因为先行词the best film 在从句中作宾语,故可省掉.
应翻译为：这是（我看过的最好的）一部电影.可以看出,括号部分是一个定语成分,修饰电影.

that 引导定语从句。这是我所看过的最好的电影

选that
此句为that引导的定语从句
that I have ever seen作film的定语
翻译:这是我看到过的最好的电影.

That

这是强调句
it is …… that……
基本句型啊
这个电影是我看过最好的
不缺成分是不用what的

that
