15．Your house may have an effect on your figure．Experts say the way you design your home could play a role in whether you put on weight or lose weight．You can make your environment work for you instead of against you．Here are some ways to turn your home into part of your diet plan．
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 fill the place with brightness．
Mind the colors．Research suggests warm colors fuel our desire to eat．In one study，people who ate meals in a blue room consumed （消费） 33percent less than those in a yellow or red room．Warm colors like yellow make food appear more attractive，while cold colors make us feel 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 70fewer calories per meal than those who rush through their meals．Begin keeping track of the time，and try to make dinner last at least 30minutes．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 22percent 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 14percent．And we'll pour about 30percent more liquid into a short，wide glass than a tall，skinny glass．

12．When you think of a forest，what do you see？Just trees？Or do you see many other things，such as small insects，worms，restless squirrels，singing birds，and colorful plants？
The forest is a whole world of its own，and it is full of many different living things．However，even though they are all different，they have one thing in common：they all need each other in order to survive．
Trees feed the animals of the forest．They make food in their leaves by using sunlight to combine water and minerals （矿物质） absorbed （吸收） from the soil and air．Their network of roots sticks into the soil and helps trees absorb water，making it possible for creature to live in it．
The earthworms，who live on the forest floor，also help to keep the soil livable and full of nutrients （营养）．Their holes in the ground allow air and water，which bear many minerals，to pass freely through the soil．
Insects，who eat the leaves of the trees，are the main food of birds．Feeding on the insects，birds help keep forest life in balance by preventing the insects from overrunning the forest．
Squirrels also play their part．They feed on the seeds of the trees，yet they，like the birds，use the branches of the trees for their homes．
Human beings are like the living things in the forest．We need one another in order to survive．We rely on farmers to grow food，truck drivers to bring it to local stores，and salesmen to sell it．We need people to prepare and cook food，and others to take garbage away．Then，of course，we need doctors and nurses to take care of us when we are sick，mail carriers，telephone operators，and newspaper delivery （递送） people to keep us in touch，as well as scientists，engineers and government leaders to improve how we live．
We also need each other in another way．We need people to talk over our problems with us，to exchange ideas，and just to chat about everyday happenings with us．Think how lonely and unhappy you would be if you lived without the companionship of other people．
Life is a matter of give and take．We need to help other people as much as we need other people to help us．Besides，think what a good feeling you have when you have done something for someone else!
