There be句型用法歸納

在實際教學中，學生對There be肯定句、否定句、疑問句句型中的be動詞以及句型中a，an，some，any的用法掌握不扎實，錯誤率較高，例如:

1. There are a desk and two chairs in the bedroom. (×)

2. There is a water in the bottle.(×)

3. There aren’t some eggs on the table.(×)

4. Are there some dolls on the bed?(×)

5. There are one book on the desk. (×)

學生們的這些錯誤，其原因可以進行如下歸納:

一、不懂就近原則

就近原則，這里指There be句型中的be動詞到底是用is還是are，由最靠近它的主語決定。以上例句There are a desk and two chairs in the bedroom.就是沒有根據就近原則，其正確寫法是There is a desk and two chairs in the bedroom.

二、對肯定句，否定句以及疑問句區別不清

肯定句:

1. There is加①a / an可數名詞單數形式 ②some / much/ a lot of不可數名詞

eg: There is a desk. There is some / much / a lot of water.

2. There are加可數名詞復數形式

eg: There are some desks.

否定句:

1. There isn’t加①a / an可數名詞單數形式 ②any+不可數名詞

eg: There isn’t a desk. There isn’t any water.

2. There aren’t加any可數名詞復數形式 eg: There aren’t any desks.

疑問句:

1. Is there加①a / an可數名詞單數形式 ②any不可數名詞

eg: Is there a desk? Is there any water?

2. Are there加any可數名詞復數

eg: Are there any desks?

三、對不可數名詞用法不清

There be句型中不可數名詞的常規用法:

肯定句:There is some / a lot of / much+不可數名詞

否定句:There isn’t any…/ There is no+不可數名詞

疑問句:Is there any / a lot of / much+不可數名詞

現將小學階段出現的一系列不可數名詞給學生歸納如下:water， juice， milk， coffee， tea， bread， rice等等，并要求學生牢記這些不可數名詞。

通過以上歸納，相信學生對開頭出現的種種錯誤會有一個重新認識，并減少出現類似錯誤的幾率。

1. There are a desk and two chairs in the bedroom.

學生通過了解就近原則可得出正解: There is a desk and two chairs in the bedroom.(√)

2. There is a water in the bottle.

學生通過water這一不可數名詞可得出正解: There is some water in the bottle.(√)

3. There aren’t some eggs on the table.

學生通過“There aren’t+any”可得出正解: There

aren’t any eggs on the table.(√)

4. Are there some dolls on the bed?

學生通過“Are there+any”可得出正解: Are there any dolls on the bed?(√)

5. There are one book on the desk.

學生知道one book為可數名詞單數，可得出正解 :There is one book on the desk.(√)
