These days most people, especially young girls, like to look slim. Our grandfather's【21】were different【22】ours, but nowadays【23】seems to enjoy【24】fat girls. That is why many companies have developed special foods to help people to slim. The only thing【25】is wrong with this is what a friend【26】said to me the other day: 'I don't mind【27】these foods if they'll give me a good figure, but why.【28】to taste so awful?' The reason is【29】the food makers have to add a lot of vitamins to these foods to satisfy the law, so the only wise advice I could give my friend was 'Eat normal food, but【30】less.' (36)
