阅读下面的文段,完成后面的答题。(12分)

①那年夏天的七月,是他一生都抹不去的黑色。

②高考前一天,父亲突患重病,医院下了病危通知书。他毅然放弃了高考,还有什么能比父亲的命更重要呢?他穿梭在医院各科室之间,交钱、拿药、取化验单……

③父亲终究还是离开了人世。从此以后,再没人为他和母亲遮风挡雨了。

④办完丧事,他想,自己必须成为一棵大树,来为母亲遮风挡雨。

⑤父亲留给娘俩的,不是财产,而是债务。父亲生前举债办了一家石粉厂,谁知厂子办起来后,产品严重滞销。

⑥他和母亲商量后,关闭了厂子,变卖了设备,连同家里积攒的钱,都用来偿还了债务。但依然有八家没能还清。都是村里的乡亲,当初父亲借钱时,他们连老底儿都拿出来了,指望着父亲年底能给一些分红,可现在……

⑦几个不眠之夜后,他告诉母亲,决定休学一年,出门打工挣钱还债。母亲长久不语,泪流满面。                          

⑧临行前,他将自己高中的课本都装在包里。他要去的是一个叫紫川的地方。那里小煤窑比较多,村里好几个人在那里打工。那一年,他十八岁。

⑨辗转奔波之后,他站在了小煤窑前。第一次下井,他惊恐不已。巷道黢黑,周围时不时有矸石坠落的声音。采煤面上很嘈杂,有用木柱支护顸板的,有打眼放炮的,还有拉拖运煤的。队长安排他拉拖运煤,不是技术活,有力气就能干。

⑩拉拖,就是将绳子拴在用汽车外胎做成的筐上,套在肩上,用近乎爬的原始方式往外运煤。运煤巷道只有半人高,根本不能直立。

⑾近一年里,他一直在巷道里拉拖。刚开始时,困扰他的是孤独、寂寞,还有累、疼。绳子紧紧地勒在后背上,磨得脊背火辣辣的疼。但他从没想过放弃。他总在盘算着,再干几天活,谁家的债就能还上了。这个念头,让他在黑暗中看到了光亮。

他慢慢适应了,后背渐渐消肿,大概已磨出茧了。他在拉拖的时候思考着高中课本上的问题,消磨漫长的时光。

⒀闲暇时间,工友们打牌喝酒。而他,捧着高中课本写写画画。晚上,别人睡了,他在被窝里用手电筒照着读书。他相信:总有一天,自己会站在大学校园里。

⒁这不是梦想。

⒂终于有一天,他真的坐在了宽敞明亮的大学教室里。打工的第二年,他还清了债务,还留有一部分结余的钱。他参加了当年的高考,被顺利录取。

⒃大学毕业后,他在这个城市安了家,把母亲接到身边,一家人其乐融融。

⒄多年后,单位组织旅游,他又到了当初打工的地方。小煤窑已不复存在,被当地政府关停,建成了旅游区。

⒅站在曾经流过汗的地方,他透过时空,看到了当年在井下匍匐拉拖的自己。

⒆他感谢那段岁月,正是当初的匍匐,才让他褪去了青涩和稚嫩,学会了真正的站立,这样的十八岁,属于真正剽悍的男人。                (摘自《解放日报》有删改)

     Jennie and I met in night school. After having completed the required courses, we started teaching in
the same school. Frequently we had lunch together.    
     For a time we were just casual friends, but one day, when I was telling Jennie about my problem son,
we discovered we were kindred spirits. "He's a difficult little character," I explained. Jennie looked
thoughtful, “Maybe you're seeing him with your eyes.” She was silent a moment and then added softly,
"It is only with the heart that one sees rightly." I stared at her, "You're quoting that! It's from The Little
Prince, SaintExupery's book for children. One of my favorites. You know it, too?" Jennie nodded, "I love
it. I've read it so often, I've practically memorized it."   
     Now, when I think of Jennie, I recall that book, because Jennie-more than anyone I know-possessed
the gift of seeing with the heart.    
     From that moment of a treasured book shared, our friendship grew steadily. It wasn't that I didn't
have an excellent relationship with my husband and son. But my mother had died shortly after my
marriage, and I had neither sisters nor daughters. I realize, now, how I needed someone to share those
little, seemingly unimportant things that add so much to life-things that must be shared to be fully
appreciated.    
     And it was Jennie who helped me with my fourthgrade problem child. One day I was at_my wit's_end. "What he needs is a good beating!" I exploded.    
     "He's probably had plenty of those,"  Jennie said. "Maybe he just needs sincere praise for anything he
does right, and a hug or two each day." I followed this suggestion, and eventually, because of Jennie, I
discovered a lovable little boy.    
     Looking back, I had to admit that she taught me so much, such as how to love spring. One April day
I said, "I hate rain!"  And I'll never forget what she said, "You can't hate spring rain! It brings the flowers!" So I learned to love spring rain, too, because it did bring flowers-violets, tulips and daffodils.

2. We learn from the passage that the author ________.
