【語法】therebe結(jié)構(gòu)-完整版課件

therebe結(jié)構(gòu)Lead-in如果要表達“某地有某人或某物”，該如何表達呢?看下面的例句：1.Thereisanappleonthedesk.桌上有一個蘋果。2.Thereissomewaterinthecup.茶杯里有一些水。3.Therearemanystudentsontheplayground.操場上有許多學(xué)生。所以，如果要表達“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+地點狀語。Thereisabirdinthetree.

Thereissomebreadontheplate.

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

Presentation3.對數(shù)量提問，一般有兩種句型結(jié)構(gòu)：如果主語是可數(shù)名詞，無論是單數(shù)還是復(fù)數(shù)都用“Howmany+復(fù)數(shù)名詞+arethere+介詞短語？”例如：

Therearetwelvemonthsinayear.

Howmanymonthsarethereinayear?

Thereisacatinthebox.

Howmanycatsarethereinthebox?

Presentation如果主語是不可數(shù)名詞，則用“Howmuch+不可數(shù)名詞+isthere+介詞短語？”例如：

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.

辦公室里有兩個男人。

Hehastwosons.
