一样的渺小

       画家早年颠沛流离,吃尽了人世的苦头。中年以后,他开始发达了——作品受到社会的广泛赞誉,名声日隆。

       如今,他的任何一幅作品,只要拿到市场上,都会引起富人们的竞价争购。可是,画家并不像别人想象的幸福与快乐,他曾经对弟子们说过这样一句意味深长的话——当我变得高大的时候,我发现,这个世界实在太渺小了。通过弟子们的传诵,此语已被世人奉为一句关于奋斗与成功的格言。其实,画家已陷入深深的孤独,在这个世界上,他除了作画,没有任何追求,而作画本身又不能给他以突破的喜悦。

      【批注:“突破”一词为小说的情节发展埋下伏笔。】

       他感觉自己被困在一个牢固的茧里,高高悬挂在人们能够仰望的地方,上不着天,下不着地。

       一天,画家偶然得知100 公里外的山上有一位老禅师,道行极高,心中顿生仰慕,决定前去拜访。为表示诚意,画家没有开自家的高级轿车,而是带着弟子们步行前往。那是一个山清水秀的地方,没有奇峰峻岭。山脚下的连绵水田里,有农夫和牛耕作的身影,村庄炊烟袅袅,头顶阳光明亮,像一首以重低音乐为背景的轻快的曲子。画家心中喜悦,按照当地人的指引,向一座小山上走去。到了山腰,画家远远看见山头上有一个农夫正躬身锄地。在蓝灰色天幕的映衬下,农夫的身影像一块人形的墨迹蠕动着。越走越近,画家看清,是一位老农在清理自己的小菜地。

      【批注:这一描写极妙:一是切合人物身份;二是虚实结合,生动形象。】

       画家汗流浃背地驻足四顾,寻找山下人说的那座小庙宇。弟子们也在一旁帮着搜寻,可是,附近并无庙宇。锄地的老者停止劳作,看着他们,目光淡定

     【批注:“淡定”一词既照应上文,又为下文“淡淡”一词张本。】

      画家问道“老人家,知道某某禅师住在哪里吗?”老者说:“我就是。”画家大喜:“有眼不识泰山,刚才我在下面就看见你了,可惜显得太渺小了。”老者淡淡地答道:“你们在山脚时我就看见了,也是一样的渺小。”场面忽然有些凝固。画家的弟子们颇为不满,觉得这禅师身怀傲气,且有争斗之心,不像那么一回事儿。但画家却没有生气,在那里愣神儿片刻,两手一拍道“回家!”

       【批注: 画家“回家”是有潜台词的。】

        后来,画家又说过一句格言,被弟子们传诵出来——当我变得高大的时候,我发现,这个世界也越发高大了。

1、画家“回家”的潜台词是:

     答:                                                                      

2、结合上下文,解读划线的两句话。

     ①这个世界实在太渺小了 

                                                                                                             

     ②这个世界也越发高大了

                                                                                                            

3、请简要概括“画家”这一人物形象。

     答:                                                                                                                                            

4、有人认为这篇小说的结尾是“蛇足”,你同意这个看法吗?请说明理由。

     答:                                                                                                                                                

                                                                                                                                                            

5、请你就文中划波浪线句子的写景作用,写一句批注。

     村庄炊烟袅袅,头顶阳光明亮,像一首以重低音乐为背景的轻快的曲子。

     批注:

(41)Orientation
Yellowstone is much more than hot ground and gushing steam. Located astride the Continental Divide, most of the park occupies a high plateau surrounded by mountains and drained by several rivers. Park boundaries enclose craggy peaks, alpine lakes, deep canyons, and vast forests. In 1872, Yellowstone became the world’s first national park, the result of great foresight on the part of many people about our eventual need for the solace and beauty of wild places.
(42) When to Go
More than half of the 3 million annum visitors come in July and August. In September and early October, the weather is good, the visitors few, and the wildlife abundant. In May and June, you can see newborn animals, but the weather may be cold, wet, and even snowy. Between about No-vember 1 and May 1 most park roads are closed to vehicles.
(43) Getting There
(44) How to Visit
The 142-mile (228.5-kilometer) Grand Loop Road forms a figure eight, with connecting spurs to the five entrances. On any visit, start with the geyser basins and Mammoth Hot Springs to see wildlife and thermal features (caution: both can be hazardous if approached too closely). On the second day, travel to the Grand Canyon of the Yellowstone, Hayden Valley, and Yellowstone Lake.
(45) Park Information
Park opens year-round.
[A] Road from North Entrance to Northeast Entrance open all year; most other park roads closed to cars November through April. Call headquarters for latest weather and road conditions.
[B] Facilities for Disabled Visitor centers, Madison and Fishing Bridge Campgrounds, most rest rooms, amphitheaters, numerous ranger-led activities, walks, and exhibits are wheelchair accessible. Free brochure available.
[C] On a longer stay, visit the Northern Range, or consider a boating or fishing trip on Yellowstone Lake; a backcountry excursion on foot or horse; or any of the numerous easy nature trails throughout the park.
[D] In early years, what made Yellowstone stand out was the extravaganza of geysers and hot springs. The wild landscape and the bison, elk, and bears were nice but, after all, America was still a pioneer country filled with scenic beauty and animals.
[E] By Plane
West Yellowstone Airport (WYS) at the West Entrance of Yellowstone. (This airport is open June through September.)
Cody Airport (COD) about 50 miles (81 kilometers) from the park.
[F] During the winter season, mid-December to mid-March, Yellowstone becomes a fantasy of steam and ice; facilities are limited but sufficient. Only the road between the North and Northeast Entrances stays open to cars, but snowmobiling is permitted on unplowed roads. Heated snow coaches offer tours and give cross-country skiers access to the 50 miles (80.5 kilometers ) of groomed trails.
