I want to thank you for giving me an opportunity to speak to you.
我要感谢大家给我一个机会来向各位讲话。
On a crowded train, one comes in contact with many people.
在拥挤的火车里面,会和许多人接触。
For example, you might pick up a travel book and read a few pages before going to sleep. It is enough to dip into it and read bits here and there. In a word, this is tasting.
