答案：1-5ADDAA
1.选A ① order作“状态”②form作“形态，形状，方式，外型” Which literary form do you like best? ③ state 状态，状况，情形The child was in a state of neglect. ④ circumstance情况，情形.
order和state的区别.state一般指思想,社会,道路,健康等情况.而这里的working order指的是机器,所以用order比较好.
2.选D ① versatile 多才多艺的 He is a versatile athlete. ② restless不安定的，焦虑的，烦躁的 Americans are historically a restless and mobile peo选项都是副词，但directly还可作连词，等同于as soon as，一……就……
3.选D 四个 of a 非常的…….(这个短语很重要一定要把这个例句背起来哦。)
4.选A muchple.而skilled相对versatile"多才多艺的"l来说,versatile更恰当.这个句子主要强调的是一个农民的多种技能.这种题目很烦,之前我也搞不清楚.
5.选A frustrate 挫败，阻挠，使感到灰心.frustrate在郎文词典中第二条是这样解释的.to prevent sb’s plans, efforts or attempts from succeeding挫败,阻挠 Their attempts to speak to him were frustrated by the guards.没特定给人使用哦.
