There be句型的主謂一致
當(dāng)be后面的名詞是可數(shù)名詞單數(shù)或不可數(shù)名詞時(shí),謂語(yǔ)用單數(shù)is(was);當(dāng)be后面的名詞是可數(shù)名詞復(fù)數(shù)時(shí),謂語(yǔ)用復(fù)數(shù)are(were)。如:
There is a river at the foot of the hill.(山腳下有條小河。)
There are two watermelons under the desk.(桌子下有兩個(gè)西瓜。)
如果be后面是多個(gè)名詞并列,be應(yīng)與靠近它的'名詞的數(shù)保持一致。如:
There is a river and many trees at the foot of the hill.(山腳下有一條小河和許多樹(shù)。)
There is a basketball and two watermelons under the desk.(桌子下有一個(gè)籃球、兩個(gè)西瓜。)
