Today's key word is fitting Dinner.

Any meal you eat in the middle of the day can be referred to as dinner.
正餐，主餐；晚餐.

Here's an example：

I'm going to dinner with this girl I have a crush on.
我要去和我喜歡的女孩吃一起吃晚餐了。

Now, let’s learn the word in the news.
A recent survey shows that in the first tier cities (一線城市), only less than a half of the people will go home on time for dinner.
In Beijing, about 40% of the people will go home for supper. That's the least among all other cities.
And people born in the 1970s --- more than 60% of them will go back on time
Those born in the 1990s---only 40%.

Notes:
-最近，中國新聞網的一項調查報告顯示，中國人，特別是生活在一線城市的人很少回家吃晚飯。
-北上廣深四大城市，準時回家(晚上6點-7點)的比例，分別為北京38%、深圳45%，廣州44%，上海45%。
-其中，北京人下班后不回家的比例最高，而上海準點下班的比例最高。
-你會經常回家吃飯嗎？不回家的理由是什么呢？
