解题思路： 如下
解题过程：
1 Try to avoid （ ） .
A dangerous B danger C to be dangerous D to dangering
选B。该句缺少宾语，名词可以直接充当宾语。句意是：尽力避免危险。
2 It's time ( ) .
A having class B to class C for class D had class
选C。It's time to do．．．“该做……了”；It's time for．．．“是……的时候了”
句型解析：It's time后可跟不定式或 for ＋名词结构，有时用It's time for sb．to do，即“该某人做……了”。例如：
It's time to begin our class．我们该上课了。
It's time for breakfast．该吃早饭了。
3 His look suggests he ( ) .A should lie B is lying C lied D putting
选B。当suggest , insist 不表示“建议，要求”时，不用虚拟。句意是：他的脸色表明他在说谎。
4 You need not do it at once,( ) ?
A needn`t you B mustn`t you C don`t you D need you
选D。need 这里是情态动词，不是行为动词，同时前面否定，疑问部分要用肯定形式。
