          一、There be句型中be 的數(shù)

          1. 在There be句型中,be后面的名詞是句子的主語,因而be的數(shù)應(yīng)與該名詞的數(shù)保持一致。后面的名詞為單數(shù)可數(shù)名詞或不可數(shù)名詞時,be應(yīng)用is;后面的名詞為復(fù)數(shù)可數(shù)名詞時,be應(yīng)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(shù)名詞,但該不可數(shù)名詞的前面有表示量的可數(shù)名詞對其進(jìn)行修飾時,be的數(shù)要與該可數(shù)名詞保持一致。如:

          There are three bottles of milk on the table.

          3. 當(dāng)后面的名詞不止一個時,be的數(shù)應(yīng)按"就近"原則來確定。如:

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

          二、There be句型中的動詞變化

          There be句型中的be還可換為其它動詞,如stand, lie, live, appear等,從而使語言更加生動形象。如:

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

          There appears to be a mistake.

          三、There be句型的各種時態(tài)

          There be句型通過be動詞的變化還可以構(gòu)成各種時態(tài)。反意疑問句中的助動詞要與各種時態(tài)相呼應(yīng)。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(qū)別

          There be結(jié)構(gòu)與充當(dāng)實義動詞的have都可作"有"講,但have作"有"講時,表示所有關(guān)系,即"擁有;占有",而There be結(jié)構(gòu)表示客觀上的存在,不說明所有關(guān)系。試比較:

          Mrs Green has three children.(說明三個小孩歸Mrs Green所有)

          There are three children under the tree.(說明樹下存在三個小孩)
