227. Judicial rules in many states require that the identi-ties of all prosecution witnesses are made known to defendants so they can attempt to rebut the testi-mony, but the Constitution explicitly requires only that the defendant have the opportunity to confront an accuser in court. (A) that the identities of all prosecution witnesses are made known to defendants so they can attempt to rebut (B) that the identities of all prosecution witnesses be made known to defendants so that they can attempt to rebut (C) that the defendants should know the identities of all prosecution witnesses so they can attempt a rebuttal of (D) the identities of all prosecution witnesses should be made known to defendants so they can attempt rebutting (E) making known to defendants the identities of all prosecution witnesses so that they can attempt to rebut In English the subjunctive mood is used to express a wish or requirement that a certain course of action be taken. Such phrasing takes the form to wish [or] require that x be y, not that x should be y or that x is y. Choice B, therefore, is best. In place of the subjunctive, A uses the indicative are and E uses an awkward gerund, making, while C and D contain the unnecessary should. A and C also omit that after so, and D omits that after require. The phrase attempt to rebut is more idiomatic than the phrases that replace it in C and D. Choices C and E awkwardly place the plural noun witnesses between the plural pronoun they and its referent, defendants. 请问so that 后的they 在语法上是不是优先指代the identities of all prosecution witnesses,但从逻辑上是指代defendants,想这种指代问题有无规律。
