     People are so  busy these days that  many  people have no time  to  cook.  This becomes a problem,

because most families  love home cooking!  The food tastes  good and warm,  and a family meal  brings

everyone together. In some families, meals are often the only times everyone sees one another at the same

time.

     Another reason  people enjoy  home cooking is that it is  often a way of showing love.  A  parent who

makes some cookies (小甜饼) is not just satisfying (满足 ) a child's sweet tooth.  She or he is sending a

message. The message says, " I care about you enough to spend an hour making cookies that you will eat up in 15 minutes if I let you. "

     There is also something about the smell of home cooking. The smell of home cooking  pleases people

of all ages. It makes most of us feel good and loved-even if we are the ones doing the cooking! Next time you smell a cake making, stop for a moment and pay attention to your mood(心情 ).
