Question

extraneous adj.外来的；无关的 (1) 外来的还原剂被引进来。(2) 由于许多外来的无法控制的因素，这些因素可能影响应变因素。(3) 无关的空语句并非总是无害的。 In Latin, extra means outside, as in extraordinary "outside the ordinary," or extraterrestrial 'coming from outside earth.' (Bonus points––ding! ding!––if you knew that terra is Latin for "earth.") The meaning of extraneous also extends to more abstract things that come from the outside: extraneous details are ones that don't matter.
