is a 还是 are a
谓语应该跟主语一致还是跟表语一致,请看下面一题:
We Chinese __________ a hard-working people.
A. is B. are C. is being D. are being
此题应选B。这里考生要注意的是:我们通常说的是主谓一致(即谓语与主语保持一致),而不是表谓一致(即不是谓语与表语一致),本题意为:我们中国人是一个勤劳的民族。
注意以下类似例子:
These two dictionaries are a present for my best friend Jim. 这两本词典是我送给我最好朋友吉姆的礼物。
The planets were the object of his study. 这些行星是他研究的目标。
The most important thing I need is books. 我需要的最重要的东西是书。
The country’s leading export is watches. 这个国家的主输出品是手表。
The best part of the meal is the coffee and cookies. 这餐饭最好的部分是咖啡和饼干。
但是有些主语由于本身具有单数和复数两种可能,它的谓语到底用单数还是复数,要看具体的语境(多数情况是看其后面词语的单复数):
1. a. Who is your brother? 谁是你的兄弟?
b. Who are your brothers? 哪些是你的兄弟?
2. a. What he said is quite correct. 他所说的完全正确。
b. What he left me are only a few old books. 他 给我留下的只是几本旧书。
