【解析】
【1】句意：校长表扬本的诚实。本因诚实而受到校长的表扬。原句为一般过去时，其被动语态结构为：was/were+动词的过去分词。主语为Ben，所以系动词用was，praise的过去分词是praised，“被”by；故答案填(1). was (2). praised (3). by 。
【2】句意：妈妈将给杰克买一件新衬衫。一件新衬衫将被妈妈买给杰克。原句为一般将来时，其被动语态结构为：will+be+动词过去分词。buy的过去分词是bought，故答案填(1). will (2). be (3). bought
【3】句意：你最好马上把受伤的士兵送去医院。这个受伤的士兵最好马上被送往医院。原句中的had better“最好”相当于一个情态动词，其后接动词原形；“被送去医院”be taken to hospital，故答案填(1). be (2). taken
【4】句意：大人们告诉孩子们不要在那条深河里游泳。孩子们被告知不要在那条深河里游泳。原句为一般现在时，其被动语态结构为：am/is/are+动词的过去分词。主语是children，所以系动词用are，tell的过去分词是told，故答案填(1). are (2). told
【5】句意：一些中国老人能听懂俄语吗？俄语能被一些中国老人听懂吗？由题干可知本句是含有情态动词的被动语态，其结构为：情态动词+be+动词过去分词。主语是Russian，understand的过去分词是understood，故答案填(1). Russian (2). be (3). understood
【6】句意：老板让员工每天工作十小时。这些员工被迫每天工作十小时。原句为一般过去时，其被动语态结构为：was/were+动词的过去分词。make sb. do sth.改为被动语态时，结构为：sb. be made to do sth.即原来的宾语补足语变为主语补足语，要恢复不定式符号to，此题为一般过去时，主语是employees，be动词用were，故答案填(1). to (2). work
【7】句意：春节受到全世界中国人的欢迎。全世界的中国人都欢迎春节。本题要求改为主动语态。原句时态是一般现在时，主语是Chinese“中国人”单复数形式一样，由句意可知这里指复数，所以谓语动词welcome用原形形式，故答案填welcome
【8】句意：最近肉的价格从十元涨到了十五元。最近肉的价格已经从十元被涨到了十五元。本题要求原句意思不变，所以可以改写成被动语态的形式，原句为现在完成时，其被动语态的构成为：have/has+been+动词过去分词；主语是The price of meat，所以助动词用has，raise的过去分词是raised，故答案填(1). has (2). been (3). raised
【9】句意：消防员正在用长梯子营救高楼里的人。长梯子正在被用来营救高楼里的人。原句的时态是现在进行时，其被动语态结构为：am/is/are+being+动词过去分词。be used for被用于…，主语是Long ladders，所以be用are，use的过去分词是used；故答案填(1). are (2). being (3). used
【10】句意：谁在幼儿园照看孩子？在幼儿园里孩子们被谁照看？原句为一般现在时，其被动语态的构成为：am/is/are+动词过去分词，本句主语是the children，所以be动词用are，本句为一般疑问句，所以are置于主语前面；look after“照顾、照看”，look的过去分词是looked；by是介词，其后接宾格形式，所以此处应用who的宾格whom；故答案填(1). whom (2). are (3). looked
