11.be in full swing 正在全力进行，处于活跃阶段
in full swing的意思是“活跃”。该习语的意思即引申为“处于（工作的）全面展开、进行阶段”。例如：the building project is in full swing.（这个建筑工程正处在全力进行之中。）

12.be in high gear 全力进行
gear指“齿轮，传动装置”，high gear的意思是汽车的“高速档”。该习语字面意思为“机器正处在高速档（快速运转）”，实际指“事物正处在全力进行当中”。
a: by the way, how is your business going? is it proceeding smoothly? 哎，你的生意最近如何？进展还顺利吗？
b: yes, it’s in high gear. 一切都在全力进行。
13.be itching for a chance to do 很想找个机会试一试
形容词itching的意思是“渴望的”，be itching to do意为“渴望做某事”；for a chance指“找机会”，因此整个习语的意思即为“渴望得到机会试做某事”。
a: i am itching for a chance to cooperate with mike. i hear he’s a very competent person. 我很想找机会和迈克合作一次。听说他特别能干。
b: everyone who has worked with him will have a deep impression on that point. 是的。每个和他一起工作的人都对此深有体会。
14.be of one mind 意见一致，看法相同

a: what do the board think about this plan? 董事会对这项计划怎么看？
b: they are of one mind in passing it. 他们一致通过。
a: good news. 太好啦。
15.be of two minds 拿不定主意
be of two minds和be in two minds的意思基本相同，均表示“左右摇摆”或“拿不定主意，下不了决心”。例如：don’t depend on him to decide. he always seems to be of two minds on important matters.（别指望他能做出决定。在重要事情上他好像总拿不定主意。）
a: are you ready to take the plunge and pound the pavements for new one? 你是否准备大胆采取措施，排除障碍，重新再来？
