1. "怎么样" in English can be translated as "How," which is typically used to inquire about the manner, condition, or situation of something. It can be used as an interrogative word to introduce a question or as a conjunction. Here are some example sentences:

1. How are you? （你好吗？）
2. How did you do that? （你是怎么做到的？）
3. How does it work? （它是怎么运作的？）
4. How much does it cost? （它多少钱？）
5. How long will it take? （需要多长时间？）

2.  "还" in Chinese is often used as a conjunction to express addition, further information, or emphasis. However, in English, depending on the specific context, it can be translated in various ways. One common approach is to use the content following "还" as a supplemental part of the conjunction "and," or to use "still" to convey the meaning of "还."
