Question

17．保护环境是我们的职责．It's our duty to protect environment．

Answer 1

分析 It's our duty to protect  environment．

解答 答案：It's our duty to protect  environment．这里是说客观事实用一般现在时，做某事是某人的职责用句型It's one's duty to do sth，…是某人的职责，"我们的"用形容词性物主代词our修饰duty，故It's our duty to，保护用protect，环境 environment作为protect的宾语，故答案是It's our duty to protect environment．

点评 理解中文含义后判断时态，分清主谓，找到句型，最后检查
