On Wednesday morning at a quarter past five came the earthquake.A moment later，the disaster was a fact.South of Market Street，in the working-class neighborhoods and in the factories，fires started.Within an hour of the first quake，the smoke could be seen 100 miles away.The sun was red in the dark sky.There was no stopping the fires.The firefighters to whom the task was given did their best but there was no way to organize or communicate.The railway tracks were now useless and there was no water in water pipes.All of the ways man had made to keep the city safe were gone in the thirty seconds the earth moved. By Wednesday afternoon，half the heart of the city was gone.At that time，I watched the disaster from a ship on the bay (海湾).Out at sea it was calm.No wind came up.Yet from every direction—east，west，north，and south—strong winds blew upon the unlucky city and those whose homes had once stood in its green hills. Wednesday night saw the destruction of the very heart of the city.Man himself had to make ruins of some of the city's best buildings so that they would not be a danger to those in the streets.Tens of thousands who had lost their homes left the city to look for shelter from the fires.Some were dressed only in blankets and carried the things that they had been able to rescue from the fires.But there were no fights and no pushing or shoving.Somehow this worst of disasters brought out the best in the survivors.Never in all of San Francisco's history were her people so kind as on this night of terror.

Open the curtains and turn up the lights.Dark environments are more likely to encourage overeating，for people are often less self-conscious (难为情) when they're in poorly lit places—and so more likely to eat lots of food.If your home doesn't have enough window light，get more lamps and flood the place with brightness. Mind the colors.Research suggests warm colors fuel our appetites.In one study，people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room.Warm colors like yellow make food appear more appetizing，while cold colors make us less hungry.So when it's time to repaint，go blue. Don't forget the clock—or the radio.People who eat slowly tend to consume about 70 fewer calories (卡路里)per meal than those who rush through their meals.Begin keeping track of the time，and try to make dinner last at least 30 minutes.And while you're at it，actually sit down to eat.If you need some help slowing down，turn on relaxing music.It makes you less likely to rush through a meal. Downsize the dishes.Big serving bowls and plates can easily make us fat.We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate.When we choose a large spoon over a smaller one，total intake (摄入)jumps by 14 percent.And we'll pour about 30 percent more liquid into a short，wide glass than a tall，skinny glass. _______________________________________________________ _______________________________________________________ _______________________________________________________ [参考范文] How to design your home affects your figure.Below are tips to design home to help diet.(要点1)Firstly，make the home brighter，because dark environments lead to eating more.(要点2)Besides，paint the room with cold colors such as blue to reduce food intake.(要点3)In addition，use the clock to record the dinner time.Since eating slowly helps take in fewer calories，make it 30 minutes or longer.(要点4)Finally，use smaller dining tools.(要点5) $$
