Ⅲ.读写任务阅读下面的短文，然后按照要求写一篇150词左右的英语短文。My mother's hands
50 years ago, for some reason, I was not accepted by the school. However, it was my mum, who held my little hands and tried countless schools and managed to get me registered.
50 years later, the day after my mother had slipped into a coma from a stroke, I sat next to her, holding her hand, stroking it, watching her body heaved up and down as she breathed heavily, like she was struggling with something.
A few days later, Mum died. At her bedside, I spent some time just looking at my mother, soaking in the finality of her death. There she was, my mother, motionless and lifeless. I took hold of her still warm but lifeless hand, holding it for the last time, recalling every piece of precious moment we spent together…
I finally let go of her hand—lifeless, yet having given so much to us—and placed it next to her body. I found myself saying silently to her the only words that came to my mind, “Goodbye Mum, thank you for everything.”
Thank you, Mother, for not giving up, so that I could go to school. Thank you for coaching me, for reading to me, for ironing my school uniforms, for combing my hair, for tying my shoe laces, for making sure I had a little handkerchief inside my pocket…
Rest in peace, Mother, you are still very much alive in us. Happy Mother's Day.

Like the author, I also appreciate my mother for everything she devotes to bringing me up.
My mother is a kind and gentle woman, a maths teacher at a middle school. As a teacher, she works diligently and treats the students patiently, so she is always praised and respected by both her students and colleagues alike. As a mother, she takes good care of me and offers me the best thing she can afford. Every day the moment she steps into the house after work, she sets about doing housework and preparing delicious dishes for me. My mother is a thrifty and industrious woman. She never buys expensive or fancy dresses for herself. Nor does she dine out in luxurious restaurants. Though she lives a simple life, she never complains.
My mother not only sets me a good example in life, but also in work. She often says, “Work while you work, and play while you play. That is the way to be happy and gay.” What a piece of good advice! I will always bear it in mind.
As far as I am concerned, nothing can be compared to Mother's love to me, and my gratitude to her is beyond words. The only thing I am able to do at present is work hard and make greater progress in study, so that I can be her pride one day.
