16．There are a large number of ants worldwide．Each individual （个人的） ant hardly weighs anything，but put together they weigh the same as all of mankind．They also live nearly everywhere，except on cold mountain tops and around the poles．For animals their size，ants have been surprisingly successful，largely because of their wonderful social behavior．
In colonies （群体） that are changing in size from a few hundred to tens of millions，they organize their lives with a clear division（分工） of labor．Even amazing is how they achieve this organization．Where we use sound and sight to communicate，ants depend on pheromones （外激素），chemicals sent out by individuals and smelled or tasted by fellow members of their colony．When an ant finds food，it produces a pheromones that will lead others straight to where the food is．When an individual ant comes under attack or is dying，it sends out an alarm pheromone to warn the colony of danger．
In fact，when it comes to the art of war，ants have no equal．They are completely fearless and will take on an animal much larger than themselves，attacking in large groups and achieve their goal．Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will lose their lives to help win an enemy．
Behaving in this selfless and devoted way，these little animals have survived on Earth for more than 140million years，longer than dinosaurs．Because they think as one，they have a united intelligence greater than you would expect from its individual parts．

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．

14．I stood there listening to my father．"Which one of you did this？"he asked with a frightening voice．
We all stared down at the floor on which was the art of a child's handwriting in chalk．I stood there and had hoped that no one else could see it．The look on my dad's face made me frightened．The only words that came from my mouth were，"Not me，Dad．"
The others denied （否认） it as well．Without saying a word，my father disappeared for just a minute and came back with a piece of paper and a pencil．He was so determined to find the truth!
"I want each of you to write exactly what you see on the step．" I was not a stupid kid，though and when my turn came，I wrote the words differently．So when my dad compared the handwriting，he still couldn't tell which one of us did it．
Frustrated，he stood a step above us and looked down at his three small kids，saying，"I'm going to give you one chance．"Not surprisingly，neither my brother nor my sister spoke up．"Well，since none of you seemed to have done it，then you all get a spanking （打屁股）．"What？Still，I stood there and said nothing．
"I did it，"I looked around to see my sister come forward．Huh？She did it？No，she didn't because I did．Why was she taking the blame for something I did？I stood there，and I let it happen．
