需要的满足直接影响学生积极性的发挥，要充分发挥学生的积极性，对学生进行有效地鼓励是教育的策略之一 。激励就是激发鼓励 。
一般地讲，激励就是以某种刺激为引诱，调动人的主动性、积极性和创造性 。教师的评语就是刺激学生的诱因 。
学生有不同的性格，有不同的需要，那么激励的方法也不同 。教师针对不同的学生及其作业，在不同场合所作的评语可激发学生的学习热情，让优等生更上一层楼，使中等生改正缺点、发扬优点，使暂时落后的学生能克服畏惧心理，树立信心 。
所以对优等生的作业表扬中要有指正，教师可通过评语向他们提出更高要求 。例如：It's good to be correct.It's also important to be creative. Excellent.You haven't made any mistakes,but do try to make your handwriting neater. 对中等生的作业要慎重评价，在评语中要多督促 。
例如：You had better be more careful!Pay more attention to the tenses. Your work is quite good except for a few spelling mis- takes. Keep it up.Remember that little by little one goes far. 对于差生的作业要多点激励，温和地指出错误的同时，也要指出他的优点以资鼓励 。例如：The structure of the composition is good,buttry to make sure the word order in your sentences is correct. Lily,I like your handwriting very much although there are some mistakes here.I am sure you can correct them. Bill,I think you can do better if you work harder. Your answers show you have real ability in the course,and you are developing increasing depth of thought and clarity of expression in your written work.However there are some grammar mistakes in the essay/here. Your work has improved.I am sure there is nothing too difficult for us to learn. You have done your work better this time.I believe that nothing is impossible as long as you work hard.Practice makes perfect. 四、作业评语要能体现师生感情的交流作业不仅是师生间教学信息的相互反馈，而且是联系和沟通师生感情的桥梁 。
在作业中教师可以觉察到学生的思想和自主学习情况，从评语中学生也能领悟出教师对他是否关心、有信心和责任心 。因此我们要充分利用作业评语加深师生情感交流 。
评语言辞恳切，切中要害；或热情鼓励、或委婉告诫……始终使学生保持清醒的头脑、强烈的兴趣、昂扬的斗志，激励并坚定他们"青出于蓝而胜于蓝"的信念 。通过评语，教师尽可把祝福、问候、关切、激励、真诚、信任之情化作甘甜的泉水，去滋润学生的心田，引起师生教与学的共鸣，达到教与学两者的和谐与统一 。
例如在节假日或某学生生日前，教师可以给予学生一些祝愿语：●Merry Christmas!/Happy New Year!/Enjoy yourself in the coming holidays!/Happy birthday1/Many happy returns！又如某个学生因为生病缺课作业完成得很糟糕，教师就要说一些安慰的话：●Lingling,you have made a few mistakes in your work.I know that is because you were absent 。I think it is only natural.Don't lose heart.I am ready to help you. 再如某个学生因为考试不及格失去信心，教师就要说一些激励的话：●Iam sorry to hear that you didn't pass the exam.I hope you are not too disappointed.I want to cheer you up with the saying"Failure is the mother of success".I nope to see much improvement in your future studies. 五、作业评语形式要丰富多彩作业评语不仅 。
