What about...?
Imagine if...
這些詞語可用來引介可能性、想法或作建議。

Imagine if they ask you to travel to exciting places.
"what if" 和 "imagine if" 可用來引介一個可能的或假想的情境。
兩者之後都要加上主詞和動詞。"what if" 會引出一個問句，因此要使用問號。"imagine if" 會引出一個敘述句，因此會使用句號。

We need to make some big changes to improve sales.
What about changing our brand identity?
What about improving the advertising campaign.
"what about" 可用來建議可能的解決方案或想法。當 "what about" 作此用途時，後面要接動名詞（V + "ing"）。"what about" 會引出一個問句，因此要使用問號。
