is to make a comment in the section below.

we can begin our lesson on 'should', 'must' and 'have to'.

我們就可以開始學習'should', 'must' 和 'have to'的課程。

'Should' 和 'must' 是真的情態動詞。

they're always followed by the 'infinitive without to'.

它們的後面總是接著"沒有to"的不定詞。

And, they're the same for all the pronouns.

而，對於所有的代名詞來說，助動詞的形態都是不變的。

"I should", "He Should", "It Should" etc.

"I should", "He Should", "It Should" 等等。

they take direct negative and question forms:

它們可以直接變化成否定形和疑問形：

And finally, they never combine with another modal verb.

最後，它們從不和其他情態動詞結合。

You can't say: "you should can". You have to replace 'can' with an alternative:

你不能說："you should can"。你必須用其他的字眼代替'can'：

It is like a modal verb because it fulfils a specific function,

它就像是個情態動詞，因為它可執行一個特定的功能，

but it behaves like an ordinary verb in its formulation.

但它的結構就像是一個普通的動詞。

It is followed by the 'infinitive without to'

but it is conjugated according to pronouns:

但是它會隨著代名詞的變化而改變：

It doesn't take direct negative and question forms.

它不能直接變化成否定形和疑問形。

And finally, it can combine with modal verbs:

最後，它能和助動詞組合起來：

The first use of should is expressing an opinion

should的第一個用法是用來表示一個見解

"I believe nurses should have higher salaries."

我認為護理師應該要有更高的薪水。

"他不應該作出一個匆忙的決定。"

"你認為我們應該要打電話給她嗎?"

"當我跟他說話的時候應該要說些什麼?"

The second usage of should is expressing an expectation.

should的第二個用法是用來表示一個期待。

And the third usage of should is expressing regret about a past action.

而should的第三個用法是用來表示對過去的行為感到後悔。

It generally sounds more formal than 'should',

一般來說，它聽起來比'should'更正式，

"他不應當作出一個匆忙的決定。"

可以被用來表示一個小的可能性。

"If I should ever go back there, I will not make the same mistake again."

"如果我可以回到那裏，我不會再犯下同樣的錯誤。"

This is a common formula in formal writing.

這在正式寫作中是一個常見的公式。

The first usage is expressing a necessity
