答案

"Before"是一个常用的时间连接词,可以引导不同类型的句子,其中包括以下四种句型:

1. 定语从句

Before引导的定语从句表示先于主语所描述的事情发生或者存在的情况。例如:

- I read the email before I left the office.(我离开办公室之前读了那封邮件。)

- The guests arrived before the dinner was ready.(宾客在餐准备好之前就到达了。)

2. 状语从句

Before引导的状语从句表示发生某个动作之前的情况。例如:

- I always drink a glass of water before I go to bed.(我睡觉前总是喝一杯水。)

- He finished his homework before he played video games.(他先做完了作业才去玩游戏。)

3. 并列句

Before可以引导含有对比意义的并列句,表示前一件事情对比后一件事情更重要。例如:

- He lost his wallet, and before that, he lost his phone.(他先是丢了电话,接着又丢了钱包。)

- Before we talk about the future, let's review the past.(我们谈论未来之前,让我们回顾一下过去。)

4. 独立主格结构

Before也可以引导独立主格结构,通常表示前置的行为可以支持后面主语的行为。例如:

- Before starting her own business, she worked at several companies.(在创业之前,她在几家公司工作过。)

- Before making any decision, he carefully weighed all the options.(在做出任何决定之前,他认真权衡了各种选项。)
