Question问：

What is the correct verb form in this sentence? "The keys to the car (are, is) on the table."

这个句子中正确的动词形式是什么?“The keys to the car (are, is) on the table.”

Answer答：

The correct sentence is "The keys to the car are on the table."

正确的句子是“The keys to The car are on The table”。

To find out whether you should use 'is' (3rd person singular) or 'are' (3rd person plural) you need to determine what the

subject of the verb

is.

要弄清楚是应该用is(第三人称单数)还是are(第三人称复数)，你需要确定动词的主语是什么。

What

is on the table?

The keys to the car.

But should the verb agree with 'keys' or 'car'? In the phrase "the keys to the car" the noun that is important (the noun that is the subject) is 'keys' because "to the car" is a

prepositional phrase

that describes the keys. The car is not the subject of the sentence. You can see this more clearly by taking out the prepositional phrase:

桌子上有什么?车钥匙。但是这个动词应该和“keys”或“car”一致吗?在短语“the keys to the car”中，重要的名词(作为主语的名词)是“keys”，因为“to the car”是一个描述钥匙的介词短语。汽车不是句子的主语。你可以把介词短语去掉，看得更清楚:

The

keys

are on the table.

钥匙在桌子上。

The car is not on the table!

车不在桌子上!
