选择题
Go to bed right away．Don’t forget you need to get up as early as you can ______ the early train．
A．catch
B．catching
C．caught
D．to catch
答案
答案：D
题目分析：考查不定式，不定式表示目的，句子意思“马上睡觉，不要忘记你需要尽可能早起床赶上早班火车”，所以选D
点评：固定词组right away意思“马上”，句子Don’t forget you need to get up as early as you…是个宾语从句，省略了引导词that，固定句型as+adj/adv+as
