在英语中，连词是连接句子或单词的重要工具。使用连词可以使句子更加流畅，表达更加清晰。那么，什么情况下需要使用连词呢？
连接句子
当我们想要连接两个句子时，需要使用连词。常见的连词有and，but，or，so等等。例如：
- I like to study English, and my sister likes to study French.
- She wanted to go to the party, but she had to study for her exam.
- You can have coffee or tea, whichever you prefer.
- I was tired, so I went to bed early.
连接词语
除了连接句子，连词还可以连接两个词语。这时我们可以使用连词and，or，as well as等等。例如：
- I need to buy milk and bread at the supermarket.
- You can choose to study abroad or work after graduation.
- She speaks French as well as Spanish.
连接复合句
复合句是由一个主句和一个或多个从句构成的句子。连接从句和主句的就是连词。常见的连词有if，when，because，although等等。例如：
- If it rains tomorrow, we will stay at home.
- When I finish my homework, I will watch TV.
- She didn't go to the party because she was feeling sick.
- Although it was raining, we still went for a walk.
总之，使用连词可以使我们的句子更加流畅、清晰、有逻辑。因此，我们需要根据句子的结构和意义来选择适当的连词。
