下面是Prep破解35题的题目和答案解释 Prep答案是C,但是我个人觉得D更好 理由:从逻辑上来讲,首先这是个并列句,But连接Suffice和Interfer并列,而且Suffice to block和not interfer with意思上也很对称 所以A、B、E 答案中but not seriously interfering不能形成独立的并列句
C答案是a substance that promotes blood clotting是一个独立主格结构中含同位语从句来说明thromboxane 但是D答案,用Which非限制性定语从句修饰thromboxane,和后面句子中用which prevents clotting修饰 prostacyclin相对称 从句子平行对称角度来将,D答案比C答案更好。 所以个人想法是选D Prep对D错误解释是 “but does…更像是跟is a substance…并列,从而作为了thromboxane的谓语动词,改变了原句的意思”
个人认为i,假如but does跟is a substance…并列的话,but前面的逗号应该没有,既然前面有逗号了,而其也没有Which连接词 那么but后面句子应该跳跃Which非限制性定语从句和a low dose of并列 以上是我个人想法,里面肯定有错误之处,尤其是对but连接对象的看法,我真没把握 还请牛人指教,谢谢! In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, which is a substance that promotes blood clotting, but not seriously interfering with the production of prostacyclin, which prevents clotting.
(A) which is a substance that promotes blood clotting, but not seriously interfering
(B) a substance that promotes blood clotting, but not seriously interfering
(C) a substance that promotes blood clotting, but does not seriously interfere
(D) which is a substance to promote blood clotting, but does not seriously interfere
(E) which is a substance that promotes blood clotting, but not a serious interference
(A) promotes…, but not…interfering…结构不平行
(C) 正确, a substance that…独立主格结构作为thromboxane的同位语对thromboxane进行解释说明; but does跳过同位语和suffices并列共同作为a low dose of aspirin的谓语动词
(D) but does…更像是跟is a substance…并列,从而作为了thromboxane的谓语动词,改变了原句的意思
(E) but not a serious语法上只能跟is a substance并列(因为前面有which is a substance that… 所以but not a serious…可以视为but is not a serious…的省略结构,但是却不能做为…usually suffices的省略结构),共同修饰thromboxane,改变了原句的意思
句子结构: …, a low dose of aspirin usually suffices to… thromboxane, a substance that promotes…, but does not…
