■由兩個部分構成一個整體的物品名詞做主語，如shoes, glasses, boots, socks, scissors, compasses, trousers, shorts等，謂語通常用復數形式。如：

His trousers are new. 他的褲子是新的。

但帶有pair這樣的量詞時，謂語要與量詞的數保持一致。如：

That pair of trousers was sold out. 那條褲子賣出去了。

■“分數（百分數）+ of + 名詞”以及 “all (most, some, any, half, a lot, part, the rest) + of + 名詞”做主語時，謂語動詞的數與of后的名詞的數一致。如：

Three-fourths of the surface of the earth is water. 地表四分之三都是水。

Twenty percent of the oranges are bad. 這桔子百分之二十都壞了。

All of my classmates like music. 我們所有的同學都喜歡音樂。

All of the water is gone. 那些水全都沒有了。

The rest of the money was stolen. 其作的錢被人偷了。

■“a (the, this, that) kind /sort / type of + 名詞”做主語，謂語用單數形式；但“these (those, all, many, some) kinds of + 名詞”做主語，謂語則用復數形式。如：

This kind of book is useful for us. 這種書對我們很用。

Many kinds of shoes are on sale in that shop. 那個店里有許多種鞋出售。

注：“名詞+ of a (the, this, that, these, those, all, some, many等) + kind(s) ”做主語，謂語動詞的數與前面名詞的數一致。如：

Book of this kind is useful for us. 這種書對我們有用。

Apples of these kinds are sour. 這種蘋果是酸的。

■在主謂倒裝的句子中，謂語動詞的數應與其后的主語一致。如：

On the wall hang two large portraits. 墻上掛著兩幅大肖像。       

Between the two rows of trees stands the teaching building. 要兩排樹之間是教學樓。
