It’s important to find a proper way to relax when we are tired.（强调合理放松的重要性） 5. 易错点辨析（贴合本单元语法）  一般现在时三单变化：重点记忆relax→relaxes、do→does、go→goes，注意study→studies（辅音+y结尾变化）  动词不定式表目的与by doing的区别：to do表“目的”（为了放松），by doing表“方式”（通过某种方式放松），如：I relax by listening to music.（方式）/ I listen to music to relax.（目的）  情态动词should/shouldn’t的用法：后接动词原形，无三单变化，否定形式直接在should后加not，缩写为shouldn’t，不可写成should not’t。 二、核心语法 —— 专项练习题（基础 + 提高） 一、用所给动词的正确形式填空 1.
