1. A at the end of, 或直接in the end
2. D 因为是for two days, 动词应选用持续状态,be away from Shanghai
3. B need若做情态动词,需要直接加动词原型而不是不定式,We need not come to school...
4. A 固定：not so ... (形容词原型）as...

C 现在完成时用by
D 表示状态的只有D，其他都是短暂动词，不能和时间连用
B 固定搭配
A 固定搭配，此次用动词原形

cdba一by表示截止某时间前的时间段,二d是延续性动词,因为有for..表一段时间动作,其他为瞬时动作不与段时间连用,三时态为一般过去,b的didn't符合,四so..as为同级比较,用形容词原级
