J'ai un oral en Anglais. Est-ce que quelqu'un pourrait me corriger les fautes de grammaire ?

Nowdays, many people use the microwave. But, what are the drawbacks and
advantages ?

First of all, since the 1rst january, 600 000 (six hundred
thousand) microwaves saled in France.

 It's amazing !

Moreover, when you've just a few minutes to eat, when you aren't
a good cooker, or when you are exhausted : you can use microwave.

Now, let us focus on the drawbacks of microwaves. On the one hand, that
can do explausde or break your plate. And on the other hand, your dish lost its
flavour and its vitamin. Furthermore, certain scientist think that waves are
awful for the organism.

Finaly, microwaves are useful and make life easier, however, we must
bear in mind that it isn't the best for the organism.

- Hey ! You hear about the British woman who put her cat in her
microwave to punish to eat the red fish ?

- No, it's dreadful ! Is the cat still alive ?

-No, it isn't. It was dead after few minutes.

- Oh my god ! My only history about microwave is when my plate, after a
few minutes in microwaves, are break in my hands. I had to go to hospital.

- It's awful !
