改错题 74.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.
【正确答案】 A
【答案解析】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。
