四级英语2021原题及答案作文【三】
Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,
XXX

Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn't afford them so you felt very depressed. There are dif-ferent views on people's clothes. The followings are my ideas:
Firstly, you shouldn't put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can't provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne
