Answer 1

分析 文章主要讲述了现在上海的高中生作业量很大，一个家长开始对此担心，并给老师发邮件建议减少作业．与此同时，很多"lion mom"出现越来越多，包括北美的一些城市，父母都成功建议学校减少了作业量．但是调查表明家庭作业的确对学生的各科成绩产生了作用，中国存在高考，要想改变作业量过多问题，必须先改变教育制度．

解答 51．night　考查名词，根据题干上海的高中生每晚有很多作业，结合each每个，可知所给的名词night是单数，故答案为night．
52．to give　 考查动词，根据空格前的动词asked，可知ask sb to do sth让某人做某事，故答案为to give．
53．swimming　考查动词，根据空格前动词like，可知like doing sth喜欢做某事，swim的现在分词是swimming，故答案为swimming．
54．because   考查连词，根据she loves her child just as a lion protects her babies．她爱她的孩子正像狮子保护它的孩子一样，可知这是解释的"狮妈"的原因，所以此处的连词应该是because因为，故答案为because．
55．growing　考查动词，根据语境，"狮妈"的数量正在增长，结合空格前的is，推出grow用现在分词形式，is growing，表示正在增长，故答案为growing．
56．its　考查代词，根据空格后名词way，推出此处是it的物主代词接名词way，故答案为its．
57．successfully 考查副词，根据advised schools to leave less homework建议学校捎给学生留作业，可知修饰动词advise要用副词，故此处是successful的副词形式successfully，故答案为successfully．
58．to　考查介词，根据题干，调查也表明了家庭作业的确对学生的各科成绩产生了作用，可知考查固定短语make a difference to对…产生作用，故答案为to．
59．does 考查动词，根据North America doesn't have a gaokao北美没有高考，but后转折，可知中国有高考，结合题干，用一个助动词代替一句话，China用单数助动词，does相当于China has a gaokao，所以does符合题意，故答案为does．
60．truth  考查名词，根据题意，大家都要面对这个事实，true 的名词是truth，此处指单数，高考一个事实，face to the truth面对事实，故答案为truth．

点评 灵活运用语法知识，如单词词性、时态、名词单复数、代词、冠词、等判断空白处应该填写的内容．填完后，还要通读全文，核对所填单词形式是否正确，是否符合语境．
