高二英語教材知識點總結及重難點解析Unit19-20
grow有“逐漸變成新狀態”之意，強調變化過程。
turn意為“變成”，表示成為完全不同的事物，強調變化的結果。其后可接形容詞作表語，一般表示東西變質，人或天氣變壞及顏色的變化等，后接名詞時，名詞前無冠詞。例如：johnson has become a lawyer, but michael remains a waiter at a hotel. johnson已做了律師，可michael卻還在一家賓館當服務員。/ don't get too excited! 不要太激動! / meat goes bad easily in summer. 肉在夏天易變壞。/ the smoke grew thicker. 煙變得更濃了。/ the milk turned sour. 牛奶酸了。 he has turned journalist. = he has become a journalist. 他已經成了一名記者。
② close shut；turn off 該組詞均表達“關，關閉”之意，但close意為“關，關閉，封閉”，是較正式的用語，常指把門窗、箱子、盒千等關閉起來或將使用著的路封閉起來。shut意為“關，關閉，關牢”，可與互換使用，但其意味更強，強調關的結果，含有關緊或關牢之意。turn off 意為“關.關閉”，常用于電源、電燈、電視、收音機等電器及水流等液體的關閉。
