151. If Dr. Wade was right, any apparent connection of the eating of highly processed foods and excelling at sports is purely coincidental.

(A)  If Dr. Wade was right, any apparent connection of the eating of

(B)  Should Dr. Wade be right, any apparent connection of eating

(C)  If Dr. Wade is right, any connection that is apparent between eating of

(D)  If Dr. Wade is right, any apparent connection between eating

(E)  Should Dr. Wade have been right, any connec­tion apparent between eating

D, the best choice, deals successfully with four issues. It uses a present indicative verb form in the conditional clause. If Dr. Wade is right, in order to agree with the verb in the main clause, any connection is...coincidental. It uses the idiomatic phrasing connection between x and y. It presents the coordinate objects of the preposition between (eating ... and excelling ...) in parallel form. Finally, the adjective apparent appears in front of its headnoun connection, not after. A, B, and E use incorrect verb forms in the conditional clause. A and B use the unidiomatic connection of x and y. A and C violate parallelism with eating of. C and E incorrectly place apparent after its head­word connection.

37. While some academicians believe that business ethics should be integrated into every business course, others say that students will take ethics seriously only if it would be taught as a separately required course.

(A)  only if it would be taught as a separately required course

(B)  only if it is taught as a separate, required course

(C)  if it is taught only as a course required separately

(D)  if it was taught only as a separate and required course

(E)  if it would only be taught as a required course, separately

Choice B is best: in sentences expressing a conditional result (x will happen ify happens), the verb of the main clause should be in the future tense and the verb of the if clause should be in the present indicative. Thus, is taught (in B) is consistent with will take, whereas would be taught (in A and E) and was taught (in D) are not. For clarity, only in C, D, and E should immediately precede the entire;/clause that it is meant to modify. Also, the intended meaning is distorted when the adverb separately is used to modify required, as in A and C, or taught, as in E; B correctly uses the adjective separate to modify course.

为什么二楼发来发区都是空白的~~中邪了~~~~~~

diyin

if 条件句子在OG语法中出现三种形式：

1） if ..do, will

2)if  did, would

3) if ..do, do

前两比较正常可以直接作为判断标准。3）需要根据其他语法点进行排除。
