they take...到lives是一個(gè)簡(jiǎn)單句,其中and連接take和try2個(gè)并列謂語(yǔ).后面doctors say后面是省略了that,引導(dǎo)一個(gè)賓語(yǔ)從句----many children are...是語(yǔ)法，比如：try to do sth盡力做某事。。。。。。。。這不是語(yǔ)法，你說(shuō)的是固定搭配吧？詞的用法呢。。。搞不懂你doctor say many children are under too much pressure和they take their children from activity to activity 中有沒(méi)有固定搭配啊有，under pressure在。。。壓力下， from...to... 一個(gè)接一個(gè)（從。。。到。。。）
