There be句型的基本用法是表示“某地(或某時(shí))有某人(或某物)”,其形式為“Therebe+代詞或名詞(短語)+地點(diǎn)/時(shí)間狀語”。
這里there是引導(dǎo)詞,沒有詞義,be是謂語動(dòng)詞,代詞或名詞(短語)是主語。be要與主語保持人稱和數(shù)的一致。否定句是在be后加not;一般疑問句是將be放在句首;反意疑問句中的簡短問句是由“be(或其否定式)+there”構(gòu)成。例如:
1.There is a desk and two chairs in the room.(緊挨著be動(dòng)詞的主語是a desk,是單數(shù),故be的形式要用is)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"。
There is an eraser and two pens on the desk.
桌子上有一塊橡皮和兩支鋼筆。
(1)如果名詞是不可數(shù)名詞,用:How much + 不可數(shù)名詞 + is there + 地點(diǎn)狀語?
How much water is there in the cup?
杯中有多少水?
2.There aren't two chairs and a desk in the room.(否定句)
3.Is there anything wrong with your ears?(Yes,there is./No,there isn't.)
4.There wasn't a meeting yesterday,was there?(反意疑問句)
除此之外,還有一個(gè)重要句式“有某人在做某事”,要用“There be +sb.+doing sth.+地點(diǎn)/時(shí)間狀語”。例如:
There are several children swimming in the river.
河里有幾個(gè)孩子在游泳。
