Unit 3重点句子讲解
1. I don’t think my arm is broken.
在动词think, believe, expect, guess等后面的宾语从句中的谓语动词如果是否定形式，这一否定形式往往转移到主句中，也就是主句成了否定形式，而从句成了肯定形式，但实际上还是否定的从句。如：
We don’t believe they can keep up with us. 我相信他们是不会赶上我们的。
2. I wanted to stop her from running after the ball, but she didn’t hear me.
句式stop … from doing … 意为“阻止……做某事”，其中的stop可用keep, prevent加以替换。如：
The heavy rain stopped us from having sports meeting. 大雨阻止了我们举行运动会。
3. “There is something wrong with me,” I thought.
由some, any, no, every 加上thing, body, one可以构成表示人或物的不定代词。比如something, anything, nothing, everything, somebody, anybody, nobody, everything等。以这类代词作主语时，谓语动词要用单数形式；并且形容词修饰这类不定代词时应该放在这些不定代词之后。如：
Everything is OK. Let’s begin our meeting. 一切都准备好了。咱们开会吧。
Is there anything new in today’s newspaper? 今天的报纸上有什么新消息吗？
