4, A will get B would get 8,A will B would
Dear Marsha
I'm not sure what to do I'm thinking of becoming a vegetable, but some of my friends say it's a bad idea. They say that if I (1)_stop_ eating meat, my body won't get all the things it needs to say healthy. Are my friends right?
Thanks,
Yuri, age 14
Dear Yuri
Millions of people vegetable and they're perfectly healthy. You have to be careful, though if you (2)_gave _ up eating meat completely, and only (3)_ate__ chocolate and crips, that would obiviously be very baf for you ! If people don't eat properly, they (4)_will get__ ill.It's that simple.If you eat lots of fruit ad salad and beans, you (5)_will__ get all the things you need to say healthy.But you're only 14years old. If you (6)__live_ at home with your parents and you probably do -you'll have to ask them what they think too. If your mum cooks for you , (7) it _will_ be difficult for her to make you special meals. If I were you, I (8)_would__ think about this carefully and maybe wait until you're a bit older before making such a big decision.
