5) I put some oil in a pan. I turn on the gas and I place (?) the pan on the flame (?). When the oil is warm (?) I put the cutlet in the pan and I let it cook on a law flame for three minutes on each side.
6)My mum prepares a (?) vegetable soup (how do you call a soup with legumes?) for me every day. I just need to heat it up (warm it over) in the microwave oven.
