Robots differ from automatic machines ___ after completion of one specific task, they can be reprogrammed by a computer to do another one.
A. in case
B. in that
C. in which
D. in time
题目解答
答案
B. in that
解析
本题考查介词短语的用法，核心在于理解句子结构中连接词的作用。关键点在于识别"differ from"的固定搭配，即"differ from... in that..."，表示“与...不同在于...”。选项中需选择能引出具体差异的连接短语。
选项分析
- A. in case：表示“以防，如果”，用于引导条件或目的从句，与题意不符。
- B. in that：表示“在于...”，用于说明差异或原因，符合题干中“机器人与自动机器的不同之处”。
- C. in which：通常指代具体事物或情况，此处无明确指代对象。
- D. in time：表示“及时”，与句意无关。
句法结构
完整句式为"A differs from B in that..."，意为“A与B的不同之处在于...”。本题中后半句"they can be reprogrammed..."即具体说明了差异，因此需用in that连接。
