    Today I tried cooking a simply dish myself. I like eating frying tomatoes with eggs, and I thought it must to be easy to cook. My mom told me how to preparing it. First I cut the tomatoes into pieces but put them aside. Next I broke the eggs into a bowl and beat them quickly with chopstick. After that I poured oil into a pan and turned off the stove, I waited patiently unless the oil was hot. Then I put the tomatoes and the beaten eggs into pan together. "Not that way," my mom tried to stop us but failed. She was right. It didn't tum out as I had wished.
