Question

my sister never washes fruit or vegetables . She says it's good for our bodies to eat a bit of dirt . Is she correct ?
No you should always wash fruit and vegetables before you eat them, because they may have fertilizers or pesticides on them , and these can be harmful .
i read in a magazine that you ought to take multivitamin pills every day as part of your daily diet . Is that right ?
No , it ...... be necessary . If you eat a normal balanced diet , you ....... take extra vitamin tablets
I`ve read somewhere that vegetables are only good for you if you eat them raw . Is this correct ?
Not quite . Of course you .... to eat raw vegetables sometimes , but cooked vegetables are fine too . But remember that you ....overcookthem ; you..... only cook them until they are just tender

Answer 1

No, it shouldn`t be necessary. If you eat a normal balanced diet, you don`t need to take extra vitamin tablets.
Of course you have (/need) to eat raw vegetables sometimes,but cooked are fine too.
But remember that you shouldn`t overcook them;you should only cook them until they are just tender.
