🎯 Lesson Goal
Learn how to give reasons using because, since, and as in everyday and professional situations. Understand when and how to use these conjunctions naturally to explain causes clearly.
🧠 Grammar Focus
Because, since, and as are conjunctions used to give reasons for something. We often use because to give a strong, clear reason, especially in spoken and written English. Since and as often introduce reasons at the beginning of a sentence and are more common in formal or written English. For example, you can say: ‘I left early because I was tired.’ or ‘Since it was raining, we stayed indoors.’ Use these conjunctions to connect two related ideas: a reason and a result. Remember, because emphasizes the cause directly, while since and as sometimes focus on background information. All three make explanations clearer and link ideas smoothly.
📖 Short Reading
Last week, I missed an important meeting because I was feeling unwell. Since I started experiencing a headache and fever, I knew it was best to rest at home. As the project deadline was approaching, I informed my team about my situation early. They understood because communication is very important in our work. Since I recovered quickly, I caught up with the tasks as soon as possible. As a result, the project was completed on time. I learned that giving clear reasons helps avoid misunderstandings and builds trust in professional environments.
