从逻辑意思上来看：你不能说是在rate之后，life expectancy 提高了，这里不存在先后顺序。而且从后面的转折来看but as late as the nineteenth century ，可以知道是两个不同时期内life expectancy 的比较。 关于after的用法，我给粘贴longman，你可以看一下，不是简单的可不可以接名词的问题： 1 when a particular event or time has happened, or when someone has done something [≠ before]:
After the war many soldiers stayed in France.
I go swimming every day after work.
Do you believe in life after death?
After you'd called the police, what did you do?
2 days/3 weeks etc after (something)
Ten years after he bought the painting, Carswell discovered that it was a fake.
the day/week/year etc after (something) (=the next day, week etc)
His car was outside your house the morning after Bob's engagement party.
Not long after the wedding, his wife became ill.
2 when a particular amount of time has passed [≠ before]: After 10 minutes remove the cake from the oven.
3 following someone or something else in a list or a piece or writing, or in order of importance:
The date should be written after the address.
After football, tennis is my favourite sport.
4 American EnglishTMC used when telling the time to say how many minutes have passed since a particular hour [= past British English] The movie starts at a quarter (=fifteen minutes) after seven.

I spend all day cleaning up after the kids.
8 because of something that happened earlier: I'm not surprised he walked out, after the way she treated him.
9 in spite of something that was done in the past: How can you treat me like this after all I've done for you?
10 when you have passed a particular place or travelled a certain distance along a road:
