什么叫“用得一世”的英语“语言能力”？ green hand
①green hand 不是望文生义的中文“绿手”，也不是“新手”
是英语：a novice, an inexperienced person, esp a sailor
是你“能说”英语：Okay.Got it.When we say someone is a green hand, we mean they are a novice, or an experienced person.If someone is a green hand, he has no experience,or is inexperienced.
这些用来解释的英语有多少你是知道的？为什么不把它们用起来理解green hand?
