This is the first time(that)I've heard her sing.
这是我头一次听她唱歌。
This is the first time I've been here.
这是我头一次来这里。
That's the seventeenth beer(that)you've drunk this evening.

It was the third time he had been in love that year.
这是他那一年第三次谈恋爱了。
This is the very pen he used when he was writing the book.

当先行词既指人又指物时，只能用that，不能用which。例：
I like the writers and their works that you mentioned the other day.
我喜欢你前几天提到的那些作家和他们的作品。
They were talking about the persons and things that they remembered in the school.
他们在谈论他们能回忆起来在学校里的人和事。
当关系代词在定语从句中作表语是，只能用that，也可以省去，不能用which。例：
China is no longer the country that it was.
中国已不是过去的中国了。
My typewriter is not the machine(that)it was.
我的打字机已不是过去的机器了。
为避免与which重复使用时，要用that。例：
Which is the car that was made in Beijing?
哪辆汽车是北京制造的？
