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 than any other child．Parents usually give first–borns 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–wording and serious.They often want to do well at school and work.There are more first–born American presidents than second or last-born children—for example,George W.Bush,George Washington,and Lyndon Baines Johnson—than the second or last-born children.
When a second child arrives,parents are not so 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.
根据短文内容,完成下列各题.
1.The writer thinks that the second children are often_____.
2.Which are more successful,the first-born,the second or last-born people?
____________________________________________________
