Passage 1
Recently, more and more teenagers are addicted to mobile phones. (1)__________ , it seems that they can't live without cellphones. It is reported that teenagers spend an average of six hours a day on their mobile phones. This has become a big concern for parents and educators.
Firstly, excessive use of mobile phones can have negative effects on teenagers' physical health. Staring at the screen for long periods of time can lead to eye strain and poor eyesight. Sitting for too long without physical movement can also cause obesity and other health problems.

This can create feelings of anxiety and low self-esteem if they don't receive the desired attention or validation.
To tackle this issue, it is important for parents and educators to establish healthy habits and boundaries for mobile phone use.
