一般将来时四大易错点：there be不能用will have、主将从现、be不能丢、won't与动词原形
引言
一般将来时的失分点集中在几处：there be 句型变将来错写成 will have、时间状语从句里该用一般现在时却用将来时、be going to 的 be 忘变。逐个拆。
易错点一：there be 变将来不能用 have
```text
错误：
There will have a football match tomorrow. ✗
There is going to have a meeting. ✗
正确：
There will be a football match tomorrow. ✓
There is going to be a meeting. ✓
原因：there 和 have 不能同框（"有"已经由 there be 表达）
```
```text
There be 变将来两种写法：
- There will be + 名词
- There is / are going to be + 名词（就近原则）
There is going to be an English test.（an test 单数 → is）
There are going to be many visitors.（visitors 复数 → are）
```
易错点二：时间状语从句"主将从现"
```text
主句用一般将来时，时间/条件状语从句用一般现在时表将来
错误：
I will call you when I will arrive. ✗
正确：
I will call you when I arrive. ✓
同理：
If it rains tomorrow, we will stay at home. ✓
（if 从句用 rains，不用 will rain）
```
```text
常见引导词：when, while, before, after, as soon as, until, if, unless
口诀：主将从现
```
易错点三：be going to 的 be 不能丢
```text
错误：
He going to buy a car. ✗
正确：
He is going to buy a car. ✓
主语变了，be 跟着变：
I am going to...
She is going to...
They are going to...
```
易错点四：will 与 be going to 在否定句中
```text
won't = will not（不是 willn't）
isn't going to / aren't going to
错误：
She doesn't going to come. ✗
He won't to go. ✗
正确：
She isn't going to come. ✓
He won't go. ✓（will 后直接跟动词原形，不加 to）
```
实战辨析
```text
- 明天将有一场篮球赛。
→ There is going to be a basketball match tomorrow.
- 我到北京后就给你打电话。
→ I will call you as soon as I get to Beijing.（从句用一般现在时）
- 如果明天下雨，我们就不去了。
→ If it rains tomorrow, we won't go.
- 他们打算下个月搬家。
→ They are going to move next month.
```
总结
```text
there be 将来：There will be / There is(are) going to be，永不用 have
时间状语从句：主将从现
be going to 的 be 随主语变，不能省
won't = will not；will 后接动词原形，不加 to
口诀：there be 不用 have，主将从现，be 别丢
```
```text
今日小抄：
There will be a football match tomorrow.（不用 will have）
I will call you when I arrive.（主将从现）
He is going to buy a car.（be 不能丢）
If it rains, we won't go.（条件从句用一般现在时）
