I’m going to talk about Bangkok, Thailand. There are many interesting places to visit, but first I want to tell you about the traffic problem. The streets are very crowded in Bangkok, so it can take a long time to get from place to place. It used to take me more than two hours to get to school by bus! I often slept on my way there! If you want to get somewhere on time in Bangkok, you must leave early. Lots of people take tuk-tuks to get through the traffic quickly. Tuk-tuks are like little cars with three wheels.

Question: What’s the traffic like in Bangkok?

参考答案：

The streets in Bangkok are very crowded.
