表示可能性：likely, unlikely, bound, definitely, probably

bound/sure 的用法

 形容詞 bound 和 sure 可以表達我們很確定某件事將會在未來發生。我們用 be bound/sure + to + 不定詞。

Jessica is bound/sure to graduate this year. 傑西卡今年一定/肯定會畢業。
The movie is bound/sure to be a mega-hit and popular. 這部電影注定/肯定會大受歡迎。

也可以用 there is/are bound/sure to be 表達我們很確定某件事會存在於未來。

There are bound/sure to be some accidents that will happen in the game, so be careful. 遊戲中必然/肯定會發生一些意外，所以要小心。

likely/unlikely 的用法

likely 和 unlikely 為形容詞。something is likely to happen 或 it’s likely that something will happen 意思是某件事很可能會發生或是被預期會發生。

如果說 something is unlikely to happen 或 it’s unlikely that something will happen 意思是某件事有可能不會發生。

這兩個形容詞可以用在兩個不同地方。

1. It is likely/unlikely that + 子句(主詞+ 動詞…)

It’s likely that in a few months we will have our separate ways after graduation. 很可能再過幾個月，畢業後我們就會分道揚鑣。
It’s unlikely that the teachers will feel sad about the new school year. 老師們不太可能對新學年感到難過。

要注意我們也可以用這些形容詞來思索過去。

2. 主詞 + be likely/unlikely + to + 不定詞

She is likely to pass the exam. 她很有可能通過考試。
We are unlikely to understand each other. 我們不太可能互相理解。

因為 likely 和 unlikely 為形容詞，所以可以有比較級或最高級的形式，或放在 quite 和 very 的後面。

Noisy students are more likely to cooperate during group work. 吵鬧的學生在小組工作中更有可能合作
They are the most likely to join the International competition. 他們最有可能參加國際比賽。
It’s very unlikely that she’ll cheat on a test. 她不太可能在考試中作弊。

definitely/probably 的用法

在肯定句中可以把 definitely 和 probably 放在主動詞之前和助動詞(如果有)之後。

You’ll definitely get what you want if you work hard for it. 如果你努力工作，你一定會得到你想要的。
She’s probably the top student in her class. 她可能是班上最好的學生。

在否定句中 definitely 和 probably 要放在助動詞之前。

They probably won’t attend the class tomorrow. 他們明天可能不會去上課了。
He definitely isn’t working overtime today. 他今天肯定沒有加班。

但如果不用縮寫的話 definitely 和 probably 要放在助動詞後面 not 前面。

They will probably not attend the class tomorrow. 他們明天可能不會去上課了。
He is definitely not working overtime today. 他今天絕對沒有加班。
