---Yes，and I think weshould be thankful to those teachers who have ever helped us（应该对那些曾经帮助过我们的老师们心存感激）．（thankful）

Answer 1

分析 should be thankful to those teachers who have ever helped us

解答 答案：should be thankful to those teachers who have ever helped us．对…心存感激用be thankful to，前面加上情态动词should，后面加上宾语那些老师those teachers，作为先行词，曾经帮助过我们的作为定语从句来修饰those teachers，关系词选择who作为定语从句的主语不可省略，表示曾经帮助过我们用现在完成时have/has+过去分词，先行词是复数，故选择have，帮助过我们用helped us，加上ever表曾经，故答案是should be thankful to those teachers who have ever helped us．

点评 这里是定语从句的应用，注意关系词的选择和谓语的单复数．
