turn up是高考英语中重要的考点。在动词turn所构成的短语中，turn up使用频度和考察频度是最高的。小编现总结如下：
turn up的用法一：开大（音量）；竖起；上扬（反弹）
由于up的基本词义是“向上（区域较高的位置、地方或程度）”，所以与动词turn（转、变）组合使用后就不难产生这样的联想：
A. 调大（电视机、收音机、电脑等）的声音; 调高(空调、暖气等)
例如：Please turn up the radio; I can’t hear a word!
请把收音机（音量）开大一点，我一个字都听不见！

May I turn up the tv?

B. 竖起（牌子、衣领等）
例如：Faced with the bitter cold, he turned up his coat collar.
面对刺骨的寒风，他竖起了衣领。
C. （股票、价值）等的上升、上扬
例如：The Shanghai Composite Index turned up by 3% yesterday.
上证综指昨天上涨了3个点。
turn up的用法二：出现、露面；被找到
由于up的另一个内涵是“靠近”，“由远至近”的感觉，如“come up here”表示“到这边来”。所以很容易联想到“turn up”可以表示一种由远至近的“到来”或“被发现、被找到”。
Don’t be too anxious, and I am sure your watch will soon turn up.
别太担心了，我保证你的手表很快会出现（被找到）。
