问题 Little he knew about the construction of the new machine, so he thought of only two ways to do it: either to ask someone else for help, or to try to operate it himself according to the instructions.

选项 A、did he know
B、he knows
C、does he know
D、he didn’t know

答案A

解析 这句话的意思是:他对这台新机器的构造知之甚少,所以他只想到两种方法——要么请别人帮忙,要么试着按照说明书自己操作。句首为否定结构或带有否定意义的词语时,句子常用部分倒装。little含有否定意义,所以当它置于句首时,后面要用倒装句式。且整个句子的时态为一般过去时,所以选A。
