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 （基因變異） 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."

2．Walk Out of the Comfort Zone and Try New Things For most high school students，free periods （課、節(jié)） are useless.From what I have seen，few do homework. （1）
.This makes it impossible for those who actually want to do work to complete any.As a senior next year，I think extra periods should be used to take optional subjects.
（2）.Now is the time for us students to choose a suitable one.We will experiment in different fields of study.We will never know if we are interested or talented in a subject if we don't try it.
In my 8th grade，I was told that I had to take an art class as a graduation requirement；so in the 9th grade I took Studio and Art.One of the projects was to build a clay pot，but I built mine incorrectly，so it broke in the kiln （窯）. （3）.Now I know for sure that I do not want to be an artist.However，the class was one of my favorites that year.I was able to try new activities and test my ability.
（4）!College is when we should focus on a specific major，but high school is when we have to figure it out.
Half of all college students change their major at some point.By doing that hundreds of dollars are wasted on classes that they would have never needed to take.So use our extra periods to find out what we want to do in college. （5）.
A.Our school offers many classes
B.We should find out what we are good at
C.I've avoided anything related to art since then
D.Instead，many are on their phones and talking
