Turning down a narrow track, we 4 and got out.We walked along a path that was thick with old pine needles.Huge black-green evergreens (常青树) 5 over us.Gradually, the peace and silence of the place began to 6 my mind. Then we turned a corner and stopped at the top of the mountain and I was entirely held in 7 .There across fields and valleys were rivers of fully-opened yellow flowers from the light one to the most brilliant.It looked as though the sun had tipped over and 8 the mountainside in gold. 9 occurred to my mind.Who created such beauty？How？When？As we approached the house that stood in the center of the property, we saw a 10 that read：“Answers to the Questions I Know You Are Asking.” The first answer was：“One Woman — Two Hands，Two Feet and Very Little Brain.” The second was: “ 11 at a Time.” The third：“Started in 1958.” As we drove home, I was so moved by what we had seen that I could 12 speak.“She changed the world，” I finally said，“one small plant at a time.She started over 60 years ago, probably just the 13 of an idea, but she kept at it.” The wonder of it would not let me go.“Imagine，” I said，“if I'd had a dream and 14 it，just a little bit every day，what might I have accomplished？” Carolyn looked at me sideways，smiling.“Start tomorrow，” she said，“ 15 yet，start today.” 语篇解读：本文为一篇记叙文。作者跟女儿来到山顶，看到满山的鲜花，被眼前的景色惊呆了。得知这是一位女士多年努力的结果，作者感受颇深：如果自己有一个梦想，并为之努力，每天努力一点，自己会取得什么样的成就呢？ √ 1．A.asked　　　　　　　 B．commanded C．insisted 　 D．predicted 解析：根据上文“...I had no desire to drive up the winding mountain road to ...”和空前的“But”可知，女儿坚持要求作者跟她去山顶。 2．A.unwillingly 　 B．undoubtedly C．unknowingly 　 D．unexpectedly 解析：根据下文“Nothing could be worth this, I thought as I along the dangerous highway.”可知，作者是不情愿来这儿的。 √ 3．A.walked 　 B．inched C．wandered 　 D．fled 解析：根据下文“the dangerous highway”可知，作者在这条危险的路上开得很慢。 √ 4．A.pulled over 　 B．stepped down C．looked up 　 D．turned off 解析：根据下文“got out”可知，作者把车停下。 √ 5．A.greeted 　 B．flowed C．reached 　 D．towered 解析：根据句意和下文“over us”可知，这些树高耸于作者和女儿的头顶。 √ 6．A.admit 　 B．fill C．control 　 D．read 解析：根据句意和空后的“my mind”可知，此处是指这里的宁静让作者心旷神怡。 √ 7．A.amazement 　 B．curiosity C．amusement 　 D．confusion 解析：根据下一句“There across fields and valleys were rivers of fully-opened yellow flowers from the light one to the most brilliant.”可知，作者被这儿的景色惊呆了。 √ 8．A.pushed 　 B．moved C．swung 　 D．bathed 解析：根据上文“tipped over”和下文“in gold”可知，此处指山坡沐浴着金色的阳光。 √ 9．A.Doubts 　 B．Ideas C．Questions 　 D．Requests 解析：根据下文“Who created such beauty？How？When？”可知，作者的脑海中出现了一些问题。 √ 10．A.signal 　 B．symbol C．symptom 　 D．sign 解析：根据空后的“...that read：‘Answers to the Questions I Know You Are Asking.’”可知，此处说的应该是标牌上的内容。 √ 11．A.Each 　 B．Some C．One 　 D．That 解析：根据下一段中的“one small plant at a time”可知，此处指的是每次种一棵。 √ 12．A.surely 　 B．barely C．mostly 　 D．instantly 解析：根据上文“As we drove home, I was so moved by what we had seen that ...”可知，此处指的是作者感动得几乎说不出话来。 √ 13．A.beginning 　 B．intention C．ending 　 D．absence 解析：根据句意和句中的“started”以及“kept at it”可知，此处指的是可能开始只是一个想法，但她坚持了下来。 √ 14．A.set off 　 B．worked out C．set down 　 D．worked at 解析：句中的“it”指的是上文的“dream”，work at the dream指的是为梦想而努力。 √ 15．A.Later 　 B．Better C．Happier 　 D．Harder 解析：根据上文“Start tomorrow”和空后的“start today”可知，此处是说今天开始更好，所以应该用better yet(更好的是)。 √ (二)语法填空(15分) Saihanba, 16 is situated in north China's Hebei Province, is a miracle as it has been transformed from wasteland to thick forest through the extraordinary efforts of three generations of Chinese people. Saihanba was home to plentiful forest resources and high biodiversity 400 years ago. With a cool summer and green vegetation, the area 17 (set) to be a royal retreat. However, massive deforestation destroyed the forest barrier, eventually turning it into a desert and resulting 18 frequent occurrences of sandstorms. To prevent sandstorms which kept 19 (strike) Beijing, the Forestry Administration decided in 1962 20 (establish)the Saihanba Forest Farm, and sent 369 foresters, mostly in their 20s, to the area for tree planting. The first foresters faced multiple challenges. 21 (equip) with only the simplest tools in extreme coldness and drought, they were unable to ensure the 22 (survive) of trees planted. Nevertheless, with joint efforts of three generations, Saihanba was restored and turned back into a paradise with a forest coverage raised from 11.4 percent to 80 percent, which can 23 (effective) conserve and purify (净化) 137 million cubic meters of water every year. The ground-breaking planting story of the foresters gives rise to 24 concept of the Saihanba Spirit, defined as working hard, advancing against difficulties and innovating daringly. As one of the largest man-made plantations worldwide, the Saihanba Afforestation Community won the honor of Champions of the Earth for their 25 (remark) green achievements. 语篇解读：本文是一篇说明文，主要介绍了河北省塞罕坝植树造林的发展变化。 16．which　考查定语从句。分析句子可知，设空处引导非限制性定语从句，先行词是Saihanba，指一个地点，在从句中作主语，所以用关系代词which。 17．was set　考查时态、语态和主谓一致。根据400 years ago可知，句子时态为一般过去时，the area与set之间是被动关系，即这个地区被设为皇家休养地，主语the area是单数，所以用was set。 18．in　考查介词。result in是固定短语，意为“导致”。 19．striking　考查非谓语动词。keep doing sth.是固定用法，意为“一直做某事”，所以strike要用v.-ing形式striking。 20．to establish　考查非谓语动词。decide to do sth.是固定短语，所以要用动词不定式形式to establish。 21．Equipped　考查非谓语动词。分析句子可知，此处为非谓语动词作原因状语，逻辑主语they与equip之间是被动关系，表示“他们被配备了最简单的工具”，所以用过去分词Equipped。 22．survival　考查名词。由空前定冠词the可知，这里需要一个名词，survive的名词形式是“survival”，意为“生存；存活”。 23．effectively　考查副词。由副词修饰动词可知，这里需要一个副词来修饰动词conserve and purify，effective的副词形式是 effectively，意为“有效地”。 24．the　考查冠词。句意：林工们开创性的植树故事，孕育了塞罕坝精神的概念，即艰苦奋斗、迎难而进、大胆创新。根据句意可知，这里特指“塞罕坝精神”的概念，所以用定冠词the。 25．remarkable　考查形容词。句意：作为世界上最大的人造林地之一，塞罕坝造林社区因其卓越的绿色成就获得了“地球卫士”的荣誉。根据句意可知，这里需要一个形容词来修饰名词achievements，remark的形容词形式是 remarkable，意为“非凡的；显著的”。 本课结束 更多精彩内容请登录：www.zghkt.cn $
