Language Points
Language points
1. Is your mother talking to her sister on the phone
你妈妈正在和她姐姐通电话吗？
【用法详解】
"on the phone" 是一个介词短语，意思是 “通电话；在打电话”，描述一个人正在进行的、与电话相关的行为状态。
Please be quiet. Your mother is on the phone.
请安静，你妈妈在打电话。
I was on the phone when you knocked at the door.
你敲门的时候，我正在打电话。
Language points
2. Did you see anything interesting at the Science Museum
你在科学博物馆看到任何有趣的事情吗？
【用法详解】anything、something、nothing 等被称为不定代词。当有形容词来修饰这些不定代词时，形容词必须放在后面，而不能放在前面。所以，我们只能说 anything interesting，绝对不能说 interesting anything。
Do you have anything interesting to tell me
你有什么有趣的事要告诉我吗？
I have something important to tell you.
我有重要的事告诉你。
