一、There be句型中be 的數

1. 在There be句型中,be后面的名詞是句子的主語(yǔ),因而be的數應與該名詞的數保持一致。后面的名詞為單數可數名詞或不可數名詞時(shí),be應用is;后面的名詞為復數可數名詞時(shí),be應用are。如:

There's some milk in the bottle.

There are many children in the park.

2. be后面的名詞為不可數名詞,但該不可數名詞的前面有表示量的可數名詞對其進(jìn)行修飾時(shí),be的數要與該可數名詞保持一致。如:

There are three bottles of milk on the table.

3. 當后面的名詞不止一個(gè)時(shí),be的數應按"就近"原則來(lái)確定。如:

There is a table, four chairs and a small bed in the room.

二、There be句型中的動(dòng)詞變化

There be句型中的be還可換為其它動(dòng)詞,如stand, lie, live, appear等,從而使語(yǔ)言更加生動(dòng)形象。如:

Many years ago, there lived an old man ...

There appears to be a mistake.

三、There be句型的各種時(shí)態(tài)

There be句型通過(guò)be動(dòng)詞的變化還可以構成各種時(shí)態(tài)。反意疑問(wèn)句中的助動(dòng)詞要與各種時(shí)態(tài)相呼應。如:

There will be a new film at the cinema, won't there?

There have been great changes in your hometown, haven't there?

四、There be與have的區別

There be結構與充當實(shí)義動(dòng)詞的have都可作"有"講,但have作"有"講時(shí),表示所有關(guān)系,即"擁有;占有",而There be結構表示客觀(guān)上的存在,不說(shuō)明所有關(guān)系。試比較:

Mrs Green has three children.(說(shuō)明三個(gè)小孩歸Mrs Green所有)

There are three children under the tree.(說(shuō)明樹(shù)下存在三個(gè)小孩)
