你觉得人们什么时候会坠入爱河呢？别人怎么知道他们相爱了呢

今天的这段对话，在谈论坠入爱河，
 
你觉得人们什么时候会坠入爱河呢？别人怎么知道他们相爱了呢
 
来听今天的讲解:
 
A: When do you think people normally fall in love? How can people know when they fall in love?
 
你觉得人们什么时候会坠入爱河呢？别人怎么知道他们相爱了呢？
 
B: I don't know. I have never had a boyfriend.
 
我不知道。我没交过男朋友。
 
A: Just imagine.
 
想想看。
 
B: I imagine that they will think about their lover every second of every minute of every day. And they will want to live together, I think that's a part of being in love. The feeling of being in love, or having a crush is different from other types of love.
 
我猜他们会每时每刻想着他们的爱人。他们会想一起生活，我觉得这是相爱的一部分。相爱或热恋是与其他的爱不同的。
 
A: At what age do people usually fall in love? Or how old do you think they have their first boyfriend or girlfriend?
 
你认为人们通常多大开始恋爱或者说有第一个男朋友、女朋友？
 
B: 20
 
20岁。
 
A: 20？People have the first boyfriend or girlfriend?
 
20岁？他们才有第一个男朋友或女朋友？
 
B: Yes, although some people are more precocious. They might meet in middle school. I also know some people who wait until they are 25 or 30. Then they find a partner. Normally in the past city kids start going steady at a slightly younger age than those from the countryside.
 
是的。虽然有些人要早熟一些——可能在中学就约会了，但我也认识一些一直等到25岁或30岁才开始找对象的人。但是一般来讲，过去城市里的年轻人找男朋友或是女朋友要早于农村的年轻人。
 
A: But one of my students told me that nowadays rural kids date at the age of 20, just as old as city kids do.
 
听我一个学生讲，现在城市的孩子和农村孩子开始恋爱的时间都大概在20岁左右。
 
B: Possibly. So far it's concerned the difference between country side and cities are not so conspicuous.
 
可能吧。城市和农村在这方面的差异并不太明显。
