B．It twitched(骤然一抽)but gradually gained height
C．It was twitched and broke down
D．It landed not 10ng after the test 请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：B
问题问“在实验的一开始机器人的行为是怎样的?做了什么动作?”利用问题句中的特征结构“atthebeginning0fthetest'’作为答案线索，并注意被选择项中B和c都涉及到了twitch，所以在文章中首先注意该词(首先重点注意B和c)，这样发现答案相关句：Tobeginwith(与atthebeginning0fthetest呼应)，therobotjusttwitchedandjerked(猛抽)erratically(不稳定地)．Butgradually，itmademovementsthatgainheight．(该句的含义与B的含义一致：首先是骤然一抽，然后逐渐升起)
