Are we getting more stupid？According to Gerald Crabtree，a scientist at Stanford University in the US，we are.
According to Dr.Crabtree，human intelligence may have actually mounted to the top more than 2，000 years ago and ever since then it has been going downhill.Dr.Crabtree states that genetic mutations （基因变异） during the past several thousands of years are causing a decrease in overall human intellectual and emotional fitness.
At the heart of Crabtree's thinking is a simple idea.Our bodies choose what genes we decide to keep and pass on what will most likely benefit our children.The study explains how our body decides to keep those traits that make us most healthy and most immune，not the ones that make us most intelligent.So since we need to be healthy but possibly not as smart，we start to lose the genes that make us smart.
There are other scientists that seem to agree with Dr.Crabtree.Ray Williams，from MIT，carried out a survey of general knowledge among public school students in his study.The data showed that 77% of the students didn't know who was the first president of America and 18% of the Americans still believed that the sun goes around the earth.So Dr.Crabtree's idea that people could be getting stupider could be factual.
However，not everyone believes in Crabtree's theory.James Flynn，the author of Are We Getting Smarter，argues that human mental abilities have grown，because we are learning what possibilities are open to us and have developed a wider variety of intelligence.
"You wouldn't get Stephen Hawking 2，000 years ago，" Thomas Hills，another opponent from the University of Warwick，says， "But now we have people of his intelligent level doing things and making insights that we would never have achieved in our environment of evolutionary adaptation."

3．Dear Laura，
Thanks for letting us to stay at your seaside house． Now， you might have heard from your neighbors about which happened on Saturday evening． When I was out a walk， my younger son， Tom， played football before your house． He made so many noise that the neighbors got quite angrily． Even worse， Tom broke one of the window of Mr． Wilson's house． Tom and I apologized to all the neighbors for the unhappy happenings， but promised to have the broken window repair soon． Tom said that we would not do such silly things any more． I am glad that your neighbors had forgiven us． They are really nice people．
Yours，
