连词or与主谓一致
这类并列主语中谓语应与哪个保持一致？你知道吗？
■You or he __________ to blame.
■_________ you or he to blame?
A. is，Is B. are，Are C. is，Are D. are，Is
此题应选C。在通常情况下，两个并列主语由or，either...or，neither...nor，not...but，not only...but (also)等连接时，其谓语通常与第二个主语(即临近的一个主语) 保持一致：
1. One or two days _________ enough to see the city.
A. is B. are C. am D. be
2. Neither my wife nor I myself _________ able to persuade my daughter to change her mind.
A. is B. are C. am D. be
3. Not only I but also Jane and Mary __________ tired of having one examination after another.
A. is B. are C. am D. be
4. Not the teacher，but the students _________ looking forward to seeing the film.
A. is B. are C. am D. be
注意在疑问句中则通常与第一个主语 (即临近的一个主语)保持一致：
a. You or he is to blame. 你或他有一人要受责备。
b. Are you or he to blame? 受责备的是你还是他?
顺便说一句，在现代英语中用neither...nor，either...or等连接主语时也可一律用复数(但考生在应试时应避免)。
