(1).____
A.make sure
B.may
C.If
D.had better not
E.so
参考答案：C
解题思路：
考查条件状语从句。句意是“如果你说没有休息好，这意味着早醒后无法再入睡，睡觉的时间断断续续，或一连数小时无法入睡。你可能总是感到疲劳、焦虑或易怒;你的记忆力和集中注意力都可能受到不良影响。”。根据上下文，只能用连词if引导条件状语从句才符合句意。
(2).____
A.make sure
B.may
C.If
D.had better not
E.so
参考答案：B
解题思路：
考查情态动词的用法。may和might可以表示可能性和许可，但是might的语气比may较婉转，表示可能性小。但在上句话里已经提到“那就意味着....,”所以，may在此更符合句意。
(3).____
A.make sure
B.may
C.If
D.had better not
E.so
参考答案：A
解题思路：
考查祈使句与词组辨析能力。make sure“设法确保，确定”。
(4).____
A.make sure
B.may
C.If
D.had better not
E.so
参考答案：D
解题思路：
考查固定词组辨析能力。had better (常简略为’d better) 是固定词组，had better“最好”，用于表示对别人的劝告、建议或表示一种愿望。其用法有以下几点：① had better 后跟动词原形(即不带to的不定式)，构成had better do sth. 句型。② 主语不论是第几人称，句子不论是什么时态，都要用had better的形式。③ 常用的否定形式是将否定副词not直接放在had better的后面。如：You had better not miss the last bus.你最好不要错过末班公共汽车。
(5).____
A.make sure
B.may
C.If
D.had better not
E.so
参考答案：E
解题思路：
考查句与句之间的逻辑关系。本句意是：“自然光有助于调节你的生物钟，所以如果可能的话，到户外去运动”。只有连词so“因此，所以”才符合句意。
