请问大全851题
851、 The work of mathematician Roger   enrose in the early 1970s, on the geometry of what are called aperiodic tiles, turned out to describe the architecture of a previously unknown class of crystals. (A) what are called aperiodic tiles, turned out to describe (B) what is called aperiodic tiles, describes (C) aperiodic tiles, describing (D) so-called aperiodic tiles, describe (E) aperiodic tiles, it turned out to describe
参考答案A
只看A/B,A的what后的are逻辑上对应work(单数),应该是错误的。B中is我认为是正确的,而describes表示客观事实,用一般现在时也不能算错。所以我认为B应该是正确答案。
不知大家有什么看法?
