10、大得多,因為很難使家長們相信自身的參與很有價值。6他很樂觀地認(rèn)為,一旦家長投入到計劃當(dāng)中,他們就會成為孩子們h常行為的榜樣,這一點與寄宿學(xué)校的學(xué)生家長完全不同。7海徳中學(xué)的辦學(xué)宗旨是:如果你向?qū)W生傳授諸如誠實、勇敢、正直、領(lǐng)導(dǎo)能力、好奇心和關(guān)心他人等美德的話,學(xué)生的學(xué)習(xí)成績自然就會 提高。8我們有兒分喜歡這種活力,但并不是喜歡它不好的一面,而是要將它轉(zhuǎn)化成好的一面。uni 141. his parents did not approve of his plan to go and study abroad with a girl they had never met, but he went
