The detox wasn't too difficult for him, but he ⑥did (do) give his phone to his dad to avoid giving in! His brother took him to their local sports centre to do an-hour sport each day, ⑦which helped him make full use of his time and made him healthier! In order not to miss the party, Max switched ⑧on his phone to check where it was, but couldn't resist having a quick look at his social media accounts. As a result, he threw in the towel on the first day! At last, the detox raised ⑨a total of ￡1,632.82 for new school sports equipment! It seems that something other than money has also been raised through the detox.⑩Awareness (aware) of just how much we rely on social media can help us step away from it and communicate with each other better. 学科网（北京）股份有限公司 $
