錢塘湖春行白居易孤山寺北賈亭西,水面初平云腳低。幾處早鶯爭暖樹,誰家新燕啄春泥。亂花漸欲迷人眼,淺草才能沒馬蹄。最愛湖東行不足,綠楊陰里白沙堤。
武漢一些小學生的家長抱怨給孩子檢查作業(yè),聽寫簽字、背誦簽字、試卷簽字……最多時一天要簽8個名,為了完成大量重復、機械的作業(yè),有時家長不得不陪寫甚至代寫,家長們質(zhì)疑,檢查作業(yè)是誰的責任?作業(yè)的目的到底是什么?這么下去。家庭作業(yè)豈不成了家長作業(yè)?學生自主學習的習慣又怎么可能養(yǎng)成?

多條技術(shù)路線并舉是我國新冠疫苗研發(fā)的布局,目前已有滅活和病毒載體兩條技術(shù)路線的新冠疫苗獲批上市。新冠疫苗有的打三針,有的打兩針,有的打一針,這是因為不同技術(shù)路線的疫苗特性不同。但其目的只有一個:保障效果和安全性。雖然制備方法、接種程序上各不相同,但目前投入接種的在接種方式(上臂三角肌注射)、年齡范圍(18周歲及以上)、安全性和最終免疫效果(均滿足世衛(wèi)組織和我國藥品審評中心CDE的保護效力要求)方面幾乎是一致的。
