定语从句中,先行词前有形容词最高级时。例如,This is the best film that I have seen.(先行词为 film,前面有 the best 修饰,此时必须用 that,强调“最好的”)

定语从句中,只能用 that 的情况:

1. 先行词前有形容词最高级时

This is the best film that I have seen.(先行词为 film,前面有 the best 修饰,此时必须用 that,强调“最好的”)

2. 先行词被 the very/the only/the same/the last 等修饰时

She is the only girl who has got a prize.(先行词为 girl,前面有 the only 修饰,此时必须用 that,强调“唯一的”)

3. 先行词被序数词修饰时

The first place that they visited was the Big Ben.(先行词为 place,前面有 the first 修饰,此时必须用 that,强调“第一”)

4. 先行词为 anything/everything/nothing/few/all/none/little/some 等词时

All that can be done has been done.(先行词为 all,此时必须用 that,强调“所有的”)

There is little that I can do for you.(先行词为 little,此时必须用 that,强调“没有”“很少”)

有些情况不一定是为了强调也会用 that,都有其各自原因。

5. 先行词前有 who,which 等疑问代词时

Who is the man that is standing there?(先行词为 man,但前面有疑问词 who,此时必须用 that。这是因为英语中为了避免重复,在一个场景下表达相同含义时,通常会使用同义词或近义词)

6. 先行词既有人又有物时

The writer and his work that you told me are really famous.(先行词有 writer 和 work,一个是人一个是物,此时必须用 that 统一)
