China is a great country with the largest population in the world．In order to solve the population problem，our government decides to have one-child policy．When it is carried out for some time，many people see not only its advantages but also its disadvantages．Therefore，one-child policy has been out of date，and two-child policy has been carried out these days．
If you have a brother or sister, you already know you are different from each other．You live together in the same house and with the same parents，but you have different personalities．
Why is this? One possible reason is the way your parents treat you·
First-born children receive all the attention from their parents．Most families have twice as many photos of a first-born as any other child．Parents usually give first-bores more responsibility(责任)and depend on them to take care of younger brothers and sisters．As a result，first-borns are often responsible，hard-working and serious．They often want to do well at school and work．There are more first-born American presidents…such as George W Bush，George Washington，and Lyndon Baines Johnson---than the second or last-born children．
When a second child arrives，parents usually feel less excited．The second child has to compete with the first-born for the parents’ attention and love．These children often choose different sports and hobbies to do well at school and work，but have to be creative to get their family’s attention．They are often friendly and cool．Many famous talk-show hosts were born last．
