【語(yǔ)法】therebe結(jié)構(gòu)-完整版課件

therebe結(jié)構(gòu)Lead-in如果要表達(dá)“某地有某人或某物”，該如何表達(dá)呢?看下面的例句：1.Thereisanappleonthedesk.桌上有一個(gè)蘋(píng)果。2.Thereissomewaterinthecup.茶杯里有一些水。3.Therearemanystudentsontheplayground.操場(chǎng)上有許多學(xué)生。所以，如果要表達(dá)“某地有某人或某物”，一般采用therebe結(jié)構(gòu)。Presentation

1.定義：

Therebe句型表示“某處存在某物或某人”。

2.結(jié)構(gòu)：（1）Thereis+單數(shù)可數(shù)名詞/不可數(shù)名詞+地點(diǎn)狀語(yǔ)。Thereisabirdinthetree.

Thereissomebreadontheplate.

（2）Thereare+復(fù)數(shù)名詞+地點(diǎn)狀語(yǔ)。Therearefifty-twostudentsinourclass.Therebe句型Presentation注意：there是引導(dǎo)詞，在句中不充當(dāng)任何成分，翻譯時(shí)也不必譯出。句子的主語(yǔ)是某人或某物，謂語(yǔ)動(dòng)詞be要與主語(yǔ)（某人或某物）的數(shù)保持一致。當(dāng)主語(yǔ)是兩個(gè)或兩個(gè)以上的名詞時(shí)，謂語(yǔ)動(dòng)詞be要與跟它最近的那個(gè)名詞一致,即遵循“就近原則”。

Therebe句型與have句型的區(qū)別

(1)Therebe句型和have都表示“有”的含義。區(qū)別如下：Therebe表示“某處存在某物或某人”；have表示“某人擁有某物/某人”，它表示所有、擁有關(guān)系:如：

Therearetwomenintheoffice.

辦公室里有兩個(gè)男人。

Hehastwosons.

他有兩個(gè)兒子。(2)當(dāng)have表示“包括”、“存在”的含義時(shí)，Therebe句型與其可互換。如：
