题型:阅读理解

题目:

Do you know that girls are seven times more likely than boys to be unhappy and twice more likely to commit suicide(自杀)and that girls are three times more likely than boys to have a negative attitude?Twenty percent of the girls in the US between the ages of 12 and 17 drink alcohol(酒)and smoke cigarettes.

So what is mental(心理的)health?Mental health is how we think,feel,and act in order to face life’s problems.

A young girl’s mental health affects her daily life and future. Like physical health,mental health is important at every stage of life. Caring for and protecting a young girl’s mental health is important to ensure that she grows up to become the best she can be.

Many children experience mental health problems that are painful and can be serious. Mental health problems affect at least one in every five young people at any given time. Unluckily,about two thirds of all young people with mental health problems are not getting the help they need. Mental health problems can lead to school failure,alcohol or other drug abuse(滥用),family violence,or even suicide.

There are many signs that may point to a possible mental health problem in a child or teenager. If you are worried about a child or have any questions,look for help at once. Talk to your doctor,a school teacher,or other mental health experts who are trained to know whether your child has a mental health problem. You can also call 1­800­789­2647 for a list of warning signs.
