1. thert be + will do (一般將來時結構之一)= there will be

2. there be + be going to do (一般將來時結構之一)= there is going to be

will/shall do和be going to do，都可以用來表示一般將來時，它們的區別到底在哪裡呢？

首先，我們來看幾個例句。

1.Next month we will have our school open day.

下個月我們將迎來學校開放日。（客觀上勢必發生的事情）

2.Now that you can't agree with him, I will tell him to find others to help him tomorrow.

既然你不能同意他的觀點，那我明天讓他去找別人幫忙。（臨時做出的打算）

3.To help the poor ，we are going to set up a temporary clinic there.

為了幫助窮人，我們打算在那裡設立一個臨時診所。（表示主觀打算）

4.Look at the dark clouds. It is going to rain.

看那烏雲，要下雨了。（根據烏雲跡象表示要下雨了）

根據上面4個例句，我們不難看出：

1.will/shall+do 表示客觀上勢必發生的事情或臨時做出的打算，常與next week,tomorrow,before long,in the future,later on,the day after tomorrow等時間狀語連用。

2.be going to+do 表示主觀計劃、打算做某事或者根據跡象表明某事即將發生。

there be句型是某地有某物，或者某處有某人

There is a book on the table

There are many people in the park

它的將來時是be going to be或者will be

明天將有一個聚會

There is going to be a party tomorrow

或者 There will be a party tomorrow

there is going to do句型不對
