英語語法講解:There be句子結(jié)構(gòu)
be動(dòng)詞單復(fù)數(shù)的確定,看be后邊第一個(gè)名詞,當(dāng)所接主語為單數(shù)或不可數(shù)名詞時(shí),be動(dòng)詞形式為is;當(dāng)所接主語為復(fù)數(shù)名詞時(shí),be動(dòng)詞為are;當(dāng)be動(dòng)詞后接兩個(gè)以上主語時(shí),be動(dòng)詞與最臨近主語保持?jǐn)?shù)上的一致。意思為"某地有某人或某物"。如:
There is an eraser and two pens on the desk.桌子上有一塊橡皮和兩支鋼筆。
There are two pens and an eraser on the desk.桌上有兩支鋼筆和一塊橡皮。

(2)therebe句型的疑問句就是將be提到句首:Bethere+(any)+名詞+地點(diǎn)狀語

(3)特殊疑問句:How many...are there(+地點(diǎn)狀語)
某地有多少人或物回答用There be...
There‘s one./There are two/three/some...
有時(shí)直接就用數(shù)字來回答。One./Two...
-How many students are there in the classroom?教室里有多少學(xué)生
