Ⅲ.根据汉语提示，选用练习Ⅱ中的句子完成语段训练

从前一位母亲和她的儿子迷了路困在了大山中。更糟糕的是，这时一只狼出现在她们面前，她们一下子不知如何是好，狼离她们越来越近。突然，这位母亲抓住了一根木棍勇敢地站在儿子的前面。她用木棍威胁狼，狼只得离开。我们从这个故事可知，母亲在危险面前敢

于献出生命来救她的儿子。可是现在许多人只注重金钱，不尊重他们的母亲甚至谴责他们自己的母亲。我认为政府应当采取措施提倡为我们的母亲做些事情。

参考答案

Once upon a time，a mother and his son lost their way，who were

trapped in a big mountain.What was worse，a wolf turned up at that time，and they didn’t know what to do at a loss.The wolf came to them nearer

and nearer.Suddenly the mother seized a stick and stood ahead of her son

bravely.She threatened the wolf with the stick，so the wolf had to go

away.From the story，we learn that a mother can sacrifice her life to save

her son in face of danger.However，a number of persons concentrate on

money，not showing respect for their mothers and even condemn their

own mothers.I think the government should take action and advocate

doing something for our mothers.

make a quilt，which she had never done before.When I asked why，she

said，“Dying is boring，and it’s never too late to learn something

new.”Over the next few months Mom worked hard on the quilt，a simple

pattern called “Grandmother’s Garden”．

As she picked up a piece of calico (印花厚布)，she would say，“This reminds me of the dress you wore on your first day of

school，”or“This blue was your father’s favorite color.” Each

recollection opened the door for a conversation about those things that

she wanted to share.As the quilt grew，Mom weakened.It was a sad

reminder that time was passing too quickly.In the end，she became too

sick to work on the quilt.

Mom died before the quilt was finished，but that was all right.She

had creatively used it as a tool to teach me her final lesson，that
