Subjunctive

[DebsWells]

I am reviewing the use and my understanding of the subjunctive. However some of the answers on the test that I undertook leave me confused. The answers provided are:-

1. It's important that she remember to take her medicine twice a day.
2. I suggest that Frank read the directions carefully before assembling the bicycle. He doesn't want the wheels to fall off while he is riding down a hill.
3. It is necessary that a life guard be monitoring the swimming pool while the children are taking their swimming lessons.
4. The sign at the pool recommended that you not swim after eating a large meal.
   

Is the verb form in the first and sentence sentences not remembers and reads ? In sentence 3 be monitoring does not come naturally to me, I was thinking it should be "monitors" and for sentence 4 I want to add the word do - "you do not"

I would be grateful for an explanation as to why these answers are correct.
Many thanks

A few things to remember about the subjunctive - we don't use any '-(e)s' endings to verbs nor 'doesn't' in negative sentences with the third person singular; additionally, we don't use 'don't' with all other persons. All we have to do is to use the simple form of the verb, the infinitive.

It is important that I (not) be... NOT ...that I am (not)...
It is necessary that she (not) apply... NOT ...that she (doesn't apply) applies...
