不要故做诚恳。要是你只是想得到一个特殊优待，学校推荐人，或得到一个职位介绍信而接近老师，他们是会察觉的。
Not being sincere. Teachers sense when your only motivation is to get special treatment, a college reference, or a job recommendation.
一个人的形象是一封无字的介绍信。人们通过你的语言、行为、仪表，就能判断出你是一个什么样的人。
The image of a person is a non-word letter of introduction. People can through your language, behavior, appearance to know what kind of a person you are.
请查收我附件里的CV，和我学校推荐人的介绍信。
