spring fever
春困

hit the sack 就寝，睡觉
It's been a long day, and now its time to hit the sack.
又是漫长的一天，终于可以睡觉了。

pull an all-nighter/burn the mid-night oil 开夜车
all-nighter 通宵的活动，通宵活动的人
Teachers do not encourage students to pull an all nighter for exams. They should pay attention during lessons.
老师不会鼓励学生在考试前才温书至深夜，他们应该上课时专心听讲才对。

sleep on it
考虑之后再做决定
