题目内容
7.让我们的家乡保持干净和美丽是我们的责任.It's our dutyto keep our hometown clean and beautiful..
分析 to keep
解答 答案:to keep.
首先通过中英文句子的比对,可知英文句子中缺少"让…保持…"的表达.短语"让…保持某种状态"的英文表达是:keep+宾语+形容词(宾语补足语).本题中,由于设空处所在的句子用的句式是:It's+名词或形容词+to do sth.,所以应该填动词不定式 故答案为:to keep
点评 做这类题型,首先根据所给汉语明确句子所要考查的单词或短语的拼写,再结合相关语法知识对单词或短语做出形式上的变化.
