The phrase "about to" is commonly used in both spoken and written English to indicate that something is going to happen or that someone is on the verge of doing something in the near future. Its usage remains consistent in both spoken and written forms. Here are some examples in both contexts:
**Spoken English:**
1. "I'm about to head out. Can I call you back later?"
- In a casual conversation, someone might say this on the phone to convey they are getting ready to leave.
2. "Wait! The bus is about to arrive."
- In an informal conversation at a bus stop, someone might use this phrase to alert others that the bus is arriving soon.
**Written English:**
1. In a formal email:
"I am writing to inform you that we are about to commence the project next week. Please review the attached documents."
2. In a news article:
"The company is about to unveil its new product line, which has generated significant excitement in the industry."
In both spoken and written English, "about to" serves the same purpose of indicating the imminence of an action or event in the near future. Its usage remains consistent and is suitable for various levels of formality.
