[shihuihsuihaohe]

I am a student and I am writing a composition right now.But I met some difficulties on using words.
Here are some quotes from my composition.

1.With the development of technology, the need for technology products is rising.Mobile phones play (Or 'have play'?) an important role in our daily life (Or 'lives'?).
2.As a middle school student, mobile phones are important in terms of education and communication (Or 'communicating'?).
3.In my opinion, the decision to allow (Or 'decisions of allowing'?) student to bring their mobile phones to school is reasonable.
4.The use of the mobile phones needs to be regulated, limiting the time and place of using them(Or 'of use'?)

I would appratieate it very much if you could give the right answer!

I am a student and I am writing a composition right now no full stop here but I met have some difficulties problems. on using words. Here are some quotes sentences from my composition.

Note my corrections above. As a learner, don't try to start sentences with the conjunction "but".

1. space here With the development of technology, the need for technology products is rising. space here Mobile phones play (or 'have play'?) an important role in our daily life (or 'lives'?).

The fact that technology is developing doesn't cause a rise in demand.
Use "play" - you're talking about a general situation. "Have play" is wrong anyway. The simple past would be "have played" but that wouldn't make sense here.
Use "our lives".

2. space here As a middle school student, mobile phones are important in terms of education and communication (or 'communicating'?).

Opening with "As a middle school student" suggests you are talking solely about yourself, saying you are currently a middle school student. If that's the case, add "for me" after "important". If you're talking about all middle school students, change the opening completely to "Mobile phones are important for middle school students in terms of education and communication".

3. space here In my opinion, the decision to allow (or 'decisions of allowing'?) students to bring their mobile phones to school is reasonable.

Use "the decision to allow". Your alternative is grammatically incorrect.
You needed the plural "students".

4. space here The use of the mobile phones needs to be regulated, limiting the time and place of using them space here (or 'of use'?)

Neither works. Say "... to limit when and where people can use them".

I would appratieate appreciate it very much if you could give the right answer help!

Install an English spell-checker on your browser. It will flag up things like the misspelling of "appreciate".

Thank you very much! Actually I'm preparing for the coming final-term-test. It has a writing part. Plus, I can't click the 'thanks' button and refreshing the website doesn't work.
