7 阅读理解。 I received a call today asking if I would be willing to bring food to a family in need. The mother was having a major operation and would be lying down for several weeks. Of course, I responded with an immediate"Yes!". As I planned the meal in my head, I thought of how many times over the years I had been asked to prepare food. I have done so countless times with a very open heart. But the truly amazing thing is that I have received double over the course of my life. When my mother died, our house was filled with fresh dinners for weeks. A woman from the church of our community stopped by each evening with some food. The gift of food was her small way of trying to ease our pain. Later in my life, when I was on bed rest during my pregnancy (怀孕) with twins, women of the church again stepped in to help. They arranged babysitting for my two-year-old daughter, and brought lovely dinners to our house. Even when I was put in the hospital, my husband would bring cooked meals to my hospital room. How we relied on these dinners to feed my tired husband and young daughter! Food is all about comfort. It feeds our bodies, but it can also feed our souls. When you hear people talking about their favorite holidays, it usually includes their feelings connected with sharing food. I know that I will have many more opportunities in my lifetime to prepare food for others. It is truly a gift I look forward to preparing and delivering to someone in need. 1.
