But a new study finds that there's another group of adolescents who are in nearly as much danger of experiencing the same psychiatric symptoms: teens who use tons of media, don't get enough sleep and have a sedentary (不愛(ài)活動(dòng)的) lifestyle.
注意在"adolescents"后面的定語(yǔ)從句中,有一個(gè)短語(yǔ)"in danger of",當(dāng)中的"as much"表達(dá)“和某物一樣多”的意思,注意冒號(hào)后面的部分其實(shí)不是句子,它的核心只是一個(gè)詞"teens",后面的"who use tons of media"和"don't get enough sleep and have a sedentary lifestyle"都是并列的關(guān)系,都是前面的"teens"的定語(yǔ),只是后面那一部分的兩個(gè)美容的關(guān)系更近一些,所以用"and"連接。
