松 明

陆 蠡

没有人伴我,我乃不得不踽踽踯躅在这寂寞的山中。

没有月的夜,没有星,没有光,也没有影。

没有人家的灯火,没有犬吠的声音。这里是这样的幽僻,我也暗暗吃惊了。①怎样地我游山玩水竟会忘了日暮,我来时是坦荡的平途,怎样会来到这崎岖的山路

耳边好像听见有人在轻语:“哈哈!你迷了路了。你迷失在黑暗中了。”

“不,我没有迷路,只是不知不觉间走得远了。②去路是在我的前面,归路是在我的后面,我是在去路和归路的中间,我没有迷路。”

耳边是调侃的揶揄。

我着恼了。我厉声叱逐这不可见的精灵,他们高笑着去远了。

萤火虫在我的面前飞舞,但我折了松枝把它们驱散。小虫,谁信你们会作引路的明灯

我于是倾听淙淙的涧泉的声音。③水应该从高处来,流向低处去。这便是说应该从山上来,流向山下去。于是我便知道了我是出山还是入山。

但是这山间好像没有流泉。即使有,也流得不响。因为我耳朵听不到泉涧的声音。

于是我又去抚摸树枝的表皮。粗而干燥的应是向阳,细软而潮润的应是背阴,这样我便可以辨出这边是南,那边是北,又一边是西,另一边是东。

但是我已经走入了蓊密的森林里。这里终年不见阳光,我便更也无法区别树木的向阳与否。

我真也迷惑了。我难道要在山间过夜,而备受这刁顽的精灵的揶揄也许有野兽来跑近我,将它冰冷的鼻放在我的身上,令我感到恶心与腥腻

我终于起来,分开野草,拿我手里的铁杖敲打一块坚硬的石。一个火星进发出来。我于是大喜,继续用杖敲打这坚石,让星火落在揉细的干枯的树叶上。于是发出一缕的烟,于是延烧到小撮的树叶,发出暗红的光。我又从松枝上折得松明,把它燃点起来,于是便有照着整个森林的红光。

我凯旋似地执着松明大踏步归来。④我自己取得了引路的灯火。这光照着山谷,照着森林,照着自己。

脑后,我隐隐听到山中精灵的低低的啜泣声。

下面对“我真也迷惑了”的原因概括正确的一项是()。

A.我游山玩水忘记了日暮,迷失在黑暗中了。

B.可恶的“山中精灵”调侃揶揄,使我不能集中精力思考。

C.我想方设法也没有找到出路。

D.暗示我对理想的追求产生了动摇。

MOSCOW — The Olympic flame in Vancouver had only been put out before President Dmitri A. Medvedev of Russia, angered over his country’s disappointing performance at the Winter Games, began calling for athletic officials’ heads.

“Those who are responsible for training for the Olympics must take responsibility,” Mr. Medvedev, who canceled his scheduled trip to the closing ceremony, said in Moscow on Monday. “They must have the courage to hand in their resignation(辞职报告). And if they do not have this determination, we will help them.”

Such language from the typically measured Mr. Medvedev strengthens the disappointment here with the nation’s athletics just four years before Russia hosts the next Winter Olympics in Sochi.

Russia is pumping billions of dollars into preparations for the 2014 Winter Games, which officials have considered as a symbol of Russia’s return to the top of the world stage.

Prime Minister Vladimir V. Putin said last week that Russia’s performance at the Olympics should be given “serious critical analysis.” “This critical analysis should be directed at improving the situation and creating the necessary conditions for the preparation and successful performance of our team in the Sochi Olympics in 2014,”   he said. Russian athletes took home just three gold medals from Vancouver, compared with eight in the last Winter Games, in Turin, Italy.

Russia came in sixth place in the overall medal count with 15, just ahead of South Korea and trailing far behind its former cold war athletic rival, the United States, which led with 37.

For Russians used to seeing their athletes top international competitions, the last two weeks have been awful. Russian figure skaters fell, bobsledders turned over and, in a final embarrassment, the country’s much proud hockey team was smacked by Canada 7-3 and did not even make the medal round.

53. The underlined word smack in the last paragraph means:

A.  guided   B. trained  C. beaten  D. controlled

54. Which sentence is true according to the passage?

A.    Russian athletes got 8 medals in the last Winter Games.

B.     South Korea ranked 5 in the overall medal count in this Winter Games.

C.     The next Winter Games will be held in Russia four years later.

D.    The Russian hockey team got the third place in this Winter Games.

55. What do we know about President Dmitri A. Medvedev ?

A. He attended the closing ceremony of the Winter Games in Vancouver.

B. He ordered a serious analysis about the Russia’s performance at the Olympics.

C. He will resign due to Russia’s performance at the Winter Olympics in Vancouver.

D. He had planned to go to Vancouver but didn’t make it.

56. What is the main idea of this passage ?

A. Russian figure skaters fell in this Winter Olympics

B. Russian will host the next Winter Olympics

C. Russians are angry about their athletes’ performance.

D. Russians are making preparations for the next Winter Olympics.
