所以填When。

Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. While文章正文：When and while are commonly used to talk about actions or events happening at the same time. However, there is a slight difference in their usage."When" is used to refer to a single, specific event that happens at the same time as another event. It emphasizes the momentary coexistence of two actions.For example, in the sentence "When I was cooking dinner, my friend called," the cooking and the phone call happened simultaneously. The focus is on the coincidence of these two events occurring at the same time."On the other hand, "while" is used to describe two ongoing or continuous actions that happen at the same time. It emphasizes the duration of the actions.For example, in the sentence "While I was cooking dinner, my friend called," both the cooking and the phone call were happening over a period of time. The focus is on the actions being carried out at the same time.Now let's move on to the practice questions:1. Fill in the blanks with "When" or "While":a) _______ I was cooking dinner, my friend called.b) _______ I was watching TV, the phone rang.c) _______ I was studying, my brother came into my room.d) _______ I was reading a book, it started to rain outside.e) _______ I was walking in the park, I saw my teacher.2. Choose the correct answer and fill in the brackets:a) _______ I was doing my homework, my favorite song came on the radio.1. When2. Whileb) _______ I was driving to work, I noticed a beautiful sunrise.1. When2. Whilec) _______ I was eating breakfast, my cat jumped onto the table.1. When2. Whiled) _______ I was sleeping, my phone rang.1. When2. Whilee) _______ I was waiting for the bus, a stranger asked me for directions.1. When2. WhileIn conclusion, "when" and "while" both indicate actions happening simultaneously, but "when" emphasizes a single specific event, while "while" highlights ongoing or continuous actions. Practice using these words to improve your understanding and fluency in English.。
