When we say a television show comes on, we mean that that is when it begins — that is when you can watch it. 当我们说“a television show comes on”，我们是指它的开始时间——也就是什么时候你可以看到它。

The national news can also be called a newscast, "newscast." 国内新闻也可以称为新闻广播(newscast)。

A newscast is a news program. 新闻广播是新闻节目。

You could have a local newscast, with just news about Los Angeles, for me, or a national newscast. 你可以看只与洛杉矶有关的地方新闻节目，或者看国内新闻节目。

Well, "During the newscast, I sort through the day's mail." 那个，“新闻播送期间，我整理了一下白天的邮件。”

To sort, "sort," through means that I am looking at today's mail “To sort through”的意思是我正在看今天的邮件，

and usually I am separating it so that I separate the different kinds of mail — the different kinds of letters — that I got that day. 我通常对其进行分类，这样我就能将今天收到的不同种类的邮件——不同种类的信件进行分类。

Most of my mail — and this is true — is either junk mail or bills. 事实上，我的大部分邮件不是垃圾邮件就是账单。

Junk, "junk," mail is mail that you get that you don't want. 垃圾(junk)邮件是指你收到了不想要的邮件。

Usually it is advertisements, people trying to get you to buy something; we call that junk mail. 通常它是广告，人们试图让你购买某物;我们称之为垃圾邮件。

Most of my mail is either junk mail or it's bills, and a bill is a statement — a piece of paper from some company that you have to pay money to. 我的大部分邮件不是垃圾邮件就是各种账单，账单就是结算单——某些公司给你的一张必须要付钱的纸条。
