阅读课文《雪》,完成小题。(12分)

暖国的雨,向来没有变过冰冷的坚硬的灿烂的雪花。博识的人们觉得他单调,他自己也以为不幸否耶?江南的雪,可是滋润美艳之至了;那是还在隐约着的青春的消息,是极壮健的处子的皮肤。雪野中有血红的宝珠山茶,白中隐青的单瓣梅花,深黄的磬口的蜡梅花;雪下面还有冷绿的杂草。胡蝶确乎没有;蜜蜂是否来采山茶花和梅花的蜜,我可记不真切了。但我的眼前仿佛看见冬花开在雪野中,有许多蜜蜂们忙碌地飞着,也听得他们嗡嗡地闹着。

孩子们呵着冻得通红,像紫芽姜一般的小手,七八个一齐来塑雪罗汉。因为不成功,谁的父亲也来帮忙了。罗汉就塑得比孩子们高得多,虽然不过是上小下大的一堆,终于分不清是壶卢还是罗汉;然而很洁白,很明艳,以自身的滋润相粘结,整个地闪闪地生光。孩子们用龙眼核给他做眼珠,又从谁的母亲的脂粉奁中偷得胭脂来涂在嘴唇上。这回确是一个大阿罗汉了。他也就目光灼灼地嘴唇通红地坐在雪地里。

第二天还有几个孩子来访问他;对了他拍手,点头,嘻笑。但他终于独自坐着了。晴天又来消释他的皮肤,寒夜又使他结一层冰,化作不透明的水晶模样;连续的晴天又使他成为不知道算什么,而嘴上的胭脂也褪尽了。

但是,朔方的雪花在纷飞之后,却永远如粉,如沙,他们决不粘连,撒在屋上,地上,枯草上,就是这样。屋上的雪是早已就有消化了的,因为屋里居人的火的温热。别的,在晴天之下,旋风忽来,便蓬勃地奋飞,在日光中灿灿地生光,如包藏火焰的大雾,旋转而且升腾,弥漫太空,使太空旋转而且升腾地闪烁。

在无边的旷野上,在凛冽的天宇下,闪闪地旋转升腾着的是雨的精魂……

是的,那是孤独的雪,是死掉的雨,是雨的精魂。

阅读理解。

     When I was going home to India last year, I called up my mother to ask if she wanted anything from

China.

     When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and

jeans. Thankfully, we can get all these anywhere in India now. 

     Still, her answer surprised me: "Green tea."

     As long as I can remember she didn't even drink Indian tea. 

     I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her

brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all

illnesses.

     At the turn of the century, China was not really familiar to the average Indian. It was a strange

country. 

     How things change! And how soon! Now every town of any size seems to have a "China Market".

And everyone is talking about China. The govemment of Indin has planned to send a team to China to

see how things are done. A minister once said that India must open the doors for more foreign

investment (投资) and such a step would "work wonders as it did for China". 

     But it's a two-way street. I just heard about a thousand Shenzhen office workers who have gone

to Bangalore to train in software. Meanwhile, all the Indian IT majors are setting up a strong presence

in China. 

     No wonder that trade, which was only in the millions just ten years ago, is expected to hit about

US $15 billion for last year and US $20 billion by 2008, a goal set by both governments. No wonder,

my colleague wrote some weeks ago about this being the Sino-Indian (中印) century as the two

countries started on January 1 the Sino-Indian Friendship Year. But what is still a wonder to me is

my mother drinking Chinese tea.

1. The reason why the writer's mother asked for Chinese green tea is that _____.[ ]

A. she had a son working in China

B. she believed it had a curing effect

C. she enjoyed Chinese products

D. she was tired of Indian tea

2. The underlined part "it's a two-way street" in Paragraph 8 probably means _____. [ ]

A. The exchanges between Indian and China benefit both

B. China and India have different traffic rules

C. Tea trade works wonders in both India and China

D. Chinese produces are popular in both China and India

3. It can be inferred from the passage that _____.[ ]

A. the author was concerned for his mother's health

B. the author was in favor of drinking Chinese green tea

C. the author was surprised at China's recent development

D. the author was curious about the growth of India's IT industry
