Question

19．中考就要到了，你最好尽快做好准备．
The Final Exam is coming，you had better get prepared as soon as possible．．

Answer 1

分析 you had better get prepared as soon as possible．

解答 答案：you had better get prepared as soon as possible．
结合句意表示最好做某事had better do sth，主语you，准备好get prepared，尽快as soon as possible，故答案是you had better get prepared as soon as possible．

点评 had better后跟动词原形（即不带to的不定式），构成had better do sth．句型．  
这里的had不能用have来替换．如：
  You'd better go to hospital at once．你最好立即去医院看病．  
  Tom，you'd better go there today．汤姆，你最好今天去那儿
