an old women had a cat.the cat was very old.she could not run quickly and she could not bite because she was so old. one day the cat saw a mouse.she jumped and caught the mouse.but she could not bite it.so the mouse got out of her mouth and ran away.the old man was very angry because the cat had not killed the muse.she wanted to hit the cat.but the cat said,“don't hill your old servant.i have worked for you for many years and i would work for you still.but i am too ould. don't be unkind to the old.remember the good work that the old did when they were young.
so old 和 too old有什么不同呢?
could not 有缩写形式吗?
后文的not bite it和前文not bite有什么不同?
i have worked for you for many years 为什么have不用过去式,而worked用了呢?为什么不用some,用many?some和many有什么不同啊?它们都是修饰什么的?意思为什么?
unkind to the old是什么意思?to是固定搭配吗?
