Would you check this sentence?

Hello

I'd like to ask about #1.
#1: It is necessary that she should do something for her son.

I think you also write #2 instead of #1. What I want to know is whether there is the case where you use "does" like #3.

Here are the sentences:
#2 It is necessary that she do something for her son.
#3 It is necessary that she does something for her son.

I look forward to a comment.
thank you.

Hi Lina,

#1 and #3 are OK. I don't know why you use " do " in #2, it must be "does" because of the third person "she".
May be what you want to know is emphasizing what's said.
eg. It's necessary that she does understand her son.

Say either:

• She should do something for her son.

Or:

• It is necessary that she do something for her son.

While "She does something for her son" is, of course, perfectly grammatical, "It is necessary that she does something for her son" is not.

Hi RonBee,

I didn't get your explanation. Please could you provide me with more examples.

I'm sorry. I have changed my mind. I have decided that sentences two and three are both correct. However, although I have tried to think of one, I do not have an explanation (especially for number two). Hopefully, Cas, Tdol or MikeNewYork will chime in with some comments.

Please be patient. :(

Actually,number two is OK- it is a present subjunctive. Such a form is less common in BE, where it has almost disappeared, than in AE, where it still has its fans.

Thanks, Tdol. Perhaps you can elaborate on the present subjunctive somewhat? (I think I confused myself initially.)

(I apologize for any confusion caused by my errror.)

The present subjunctive (marked by no third person inflection) is used in noun clauses that come after a number of verbs, particularly those associated with urgency or obligation.

It is important that John leave now.
It is urgent that he be admitted immediately.
It necessary that she appear in court.
It is time that he left.
It is high time that John begin his project.

In British English, this form is becoming increasingly rare and formal.

And it's a darned shame too.
