Question

A mobile phone is a child’s best friend, a companion who is misguiding a child’s life, ruining every moment a child progresses in their wisdom.

Answer 1

Can someone check this for me?

Answer 2

What is the context?

Answer 3

Why children shouldn't have mobile phones

Answer 4

Your sentence is fine.

Be sure to support it with solid facts.

Answer 5

I think you must explain why a mobile phone misguides a child's life and how it ruins his or her progress.

Answer 6

A mobile phone is a child’s best friend, a companion who is misguiding a child’s life, ruining every moment a child progresses in their wisdom. We should realise that a cold object that is stuck on an individual’s hands 24/7 will greatly impact their social life. Isn’t your child’s safety the most vital thing to you? Trust should not be taken at a degree...

Answer 7

Does it make sense?

Answer 8

Contradictory:
<i>A mobile phone is a child’s best friend, a companion who is misguiding a child’s life, ruining every moment a child progresses in their wisdom. </i>

Unexplained:
<i>We should realise that a cold object that is stuck on an individual’s hands 24/7 will greatly impact their social life.</i>

You have 3 different "voices" here -- 1st, 2nd, and 3rd. Pick one and stay with it.

Answer 9

Alright

Answer 10

Okay i'm against mobile phone, so what can i say instead of best friend?

Answer 11

I'd simply make that first part negative: A mobile phone is not a child's best friend...

Answer 12

There are grammatical issues in here, too. Here's one:

"... a cold object that is stuck on an individual’s hands 24/7 will greatly impact their social life."

You have written about "a child" and "an individual" here, but then you write "their." How will you make them all the same -- either all singular or all plural?
