take place, happen, occur, come about和break out用法区别

这些词或短语都有“发生”的意思，但用法各不相同，区别如下：

(1). take place 表示“发生、举行、举办”，一般指非偶然性事件的“发生”，即这种事件的发生一定有某种原因或事先的安排，例如：

Great changes have taken place in our hometown during the past ten years.

The Olympic Games of 2008 will take place in Beijing.

(2) .happen作“发生、碰巧”解，一般用于偶然或突发性事件，例如：

What happened to you? (一般不说：What did you happen?)

Maybe something unexpected happened.

I happened to see him on my way home.

= It happened that I saw him on my way home.

(3). occur作“发生、想到、突然想起”解，其意义相当于happen，例如：

What has occurred? (=What has happened?)

A big earthquake occurred (=happened) in the south of China last month.

It occurred to me that she didn’t know I had moved into the new house.

(4). come about表示“发生、产生”，多指事情已经发生了，但还不知道为什么，常用于疑问句和否定句，例如：

When Mother woke up, she didn’t know what had come about.

I’ll never understand how it came about that you were late three times a week.

Do you know how the air accident came about?

(5). break out意思为“发生、爆发”，常指战争、灾难、疾病或者争吵等事件的发生，也可以表示突然大声叫喊等，例如：

Two world wars broke out last century.

A fire broke out in the hospital in the mid-night.

After the flood, diseases broke out here and there.

She broke out, “That is too unfair!”
3.
1)强调重点不同

两者都表示必须，但must 侧重于说话者的主观看法，认为有必要或有义务去做某事；have to 则重于客观需要，含有不得不或被迫之意：

We must go at once. 我们必须马上就走。

If I buy that car， l have to borrow some money. 如果我要买那辆汽车，我得借些钱。

2)时态形式不同

must 只有现在时一种形式（在宾语从句中可以表示过去），而 have to 则有多种时态形式：

She said （that） she must go with me. 她说她一定要同我一起去。

They have had to buy a car. 他们不得不买了辆小汽车。

3)非谓语形式不同

have to 可以有分词、动名词、不定式等形式，而 must 则没有这些形式：

He only saw her in the evening，having to be away all day. 他整天得外出，只能晚上见她。

I regret to have to trouble you again. 我很抱歉不得不再麻烦你一次。

4)否定式的意义不同

must 的否定式 mustn‘t 意为一定不要、不允许；

而 have to 的否定式 don’t have to 意为不必（=needn‘t）。比较：

You mustn‘t tell him about it.你一定不要告诉他这件事。（可能是秘密）

You don‘t have to tell him about it.你不必告诉他这件事。（他可能知道了）
