1.       A letter by Mark Twain,written in the same year as TheAdventures of Huckleberry Finn were published, revealsthat Twain provided financial assistance to one of the first Black students atYale Law School.
(A) A letter byMark Twain, written in the same year as TheAdventures of Huckleberry Finn were published,
(B) A letter byMark Twain, written in the same year of publication as The Adventures of Huckleberry Finn,
(C) A letter byMark Twain, written in the same year that TheAdventures of Huckleberry Finn was published,
(D) Mark Twainwrote a letter in the same year as he published The Adventures of Huckleberry Finn that（C）
Inthis sentence, the relative pronoun thatshould introduce the clause TheAdventures... published to make a relative clause modifying year. Also, the singular title of thenovel demands a singular verb: for example, one would say, “The Adventures of Huckleberry Finn is (not “are”) a great book.”Only C, the best choice, satisfies both requirements. Choices A and Dincorrectly substitute as for that to introduce the relative clause.Choice A also mistakes the novel title for a plural (were published). B confuses meaning (written in the same year of publication as). E creates a similarconfusion of meaning, and both D and E are awkward and imprecise because that is too far away from its referent (letter) to be clear.
不是太懂为什么这里A的as不行，除了那个were错了
