【題目】It was December and the snow was falling quietly outside. The four March sisters were sitting around the fire in the living room. They were knitting(織)socks for soldiers(士兵).There was a war and everyone had to help.

Meg was the oldest of the four sisters. She was sixteen. She was very pretty and she loved pretty clothes. Jo was fifteen. She was very tall and thin. She was different from Meg. She didn't care about dresses or hairstyles. She was a tomboy(假小子).Beth was thirteen. She was very shy and quiet and she seemed to live in a happy world of her own. The youngest, Amy, looked like a snow princess with her blue eyes. She loved beautiful things and she was a little vain(虛榮的)?She also thought that she was a very important person.

"Christmas isn't Christmas without any presents," Jo said sadly. "I hate being poor!" Meg said, looking at her old dress.

"Some girls have lots of nice things, and other girls have nothing at all," said Amy. "I don't think it's fair!"

"But we've got Father and Mother, and each other," said Beth.

The four sisters looked happy for a moment when they remembered this.

"But we haven't got Father," said Jo. Their smiles suddenly disappeared. Mr March was far away with the soldiers.

"Mother says our men are suffering(受苦)and we mustn't spend money for pleasure," Meg said."That's why we can't have presents this year."

"Well, each of us has a dollar to spend," said Jo. "What can the army do with four dollars?

Nothing! I don't expect anything from Mother but I'd like to buy a book for myself !" Jo loved reading.

"I want to spend mine on some new music," said Beth. She played the piano and she loved singing.

"I'm going to buy a box of drawing pencils. I really need them!" said Amy. She wanted to be an artist.

"Mother didn't say anything about spending our own money," cried Jo. "We work hard for it so let's buy what we want and have a little fun."

It was true. The two older sisters had jobs. Meg worked as a teacher for the King family and Jo looked after Aunt March, their father's rich, bad-tempered(壞脾氣的)old aunt. Beth and Amy helped with the housework.

【1】What was Jo's hobby?

A. Knitting.B. Singing.C. Drawing.D. Reading.

【2】On a snowy day, the March sisters are .

A. complaining about having no money for Christmas presents

B. talking about what presents they will buy with some money

【3】The passage is probably from .
