The water and grass were on the left, while the desert was on the right. Because the mother had been blind in her left eye since she was a baby, she could see nothing with her left eye.

四、任务型阅读（本题共5小题，每小题2分，共10分。）
There are many things in the world that we don’t understand, and know little about. In 1832, an explorer traveled to the Himalayas (喜马拉雅山脉). The people there told him stories about a strange animal called yeti (雪人). “It lived in the snow,” they said. It was very tall, and much bigger than a man. The explorer didn’t believe the stories. “These people have probably seen a big monkey,” he thought.
But the stories about the yeti continued. A lot of explorers went to the Himalayas. They wanted to find the yeti. Some of the climbers told stories about a strange animal in the snow, but nobody could prove (证实) they had seen it.
In 1925, a photographer named Tombazi said he saw a yeti when he was climbing. It was about 300 metres away from him. He was with some other people, and they saw the yeti, too. Tombazi tried to take a picture, but the yeti was gone! Tombazi went to look at the snow and he found footprints. They were huge!
The best clue about the yeti comes from a scientist called Gene Poirier. He traveled to Himalayas and collected pieces of hair. When people examined the hair, they found something amazing. The hair did not come from any normal animal. Maybe it’s the first real proof (证据) of the yeti!
31．In which century was the explorer told there lived a yeti in Himalayas?
______________________________________________________
32．Has anyone got a picture of a yeti yet?
______________________________________________________
33．The yeti runs very fast, doesn’t it?

【分析】这篇文章主要讲述了人们对雪人的探索和发现。1832年，有探险家在喜马拉雅山听到了有关于雪人的描述，据说那是比人高大的一种动物。其后有许多探险家到喜马拉雅山去寻找雪人，其中一些登山者讲述了雪中的一种奇怪动物的故事，但是没有人能证明他们曾看到过。1925年，一位摄影家说他看到了雪人，但是没能拍下照片。但是他发现了它们的脚印，非常的巨大。关于雪人最好的线索是科学家Gene Poirier发现的几片毛发。
31．细节理解题。根据In 1832, an explorer traveled to the Himalayas (喜马拉雅山脉). The people there told him stories about a strange animal called yeti (雪人). 1832年，一位探险家前往喜马拉雅山。那里的人告诉他关于一种叫做雪人的奇怪动物的故事。可知，在19世纪，有人告诉探险家喜马拉雅山有一只雪人。故答案为In the 19th century.

34．细节理解题。由句子The hair did not come from any normal animal. Maybe it’s the first real proof (证据) of the yeti! 头发不是正常动物的。也许这是雪人的第一个真实证据！可知，头发可能是雪人的第一个真正证据。故答案为The hair.
35．句子翻译题。The best clue about the yeti：“有关雪人的最佳线索”；comes from：“来自于……”；a scientist called：“一位叫……的科学家”；Gene Poirier：“吉恩·普瓦堤埃”。所以翻译结果是：有关雪人的最佳线索是来自一位叫吉恩·普瓦堤埃的科学家。
【点睛】回答问题的任务型阅读
该题型是给同学们呈现一段阅读资料，然后设置几个问题，做题时，我们应该先浏览一下问题，心中对所给任务有一个初步的了解，带着问题去阅读，有针对性地阅读，提高阅读效率。
一、阅读全文，了解大意
在做任务型阅读题时，同学们应先浏览文章后所提出的问题，在浏览过任务后，应迅速回头阅读全文了解文章的主要内容，作者想表述的观点，情感等。
二、寻找细节，逐题攻克
对于任务型阅读中的细节考查题，需要同学们有对语言的理解和分析能力，并带着问题回到阅读材料中，采用跳读的方式来寻找细节所在的段落，然后锁定目标段落，寻找总结自己所要的答案。
此外，同学们在答题和书写方面还要注意以下几点：
1. 作答时，要遵循的原则就是：能简略回答的，尽量简略回答。
2. 书写要规范整洁。句子开头首字母要大写；标点符号要规范，单词拼写要正确无误；注意时态的呼应和人称的转变。
3. 做出适当调整。在回答时，同学们应对照题目，根据需要对句子的人称、单复数、时态、语态、词性、主谓搭配等做出适当的调整。
三、通读全文，仔细检查
在完成所有的答题任务后，同学们一定要检查一下自己的答案：是否存在书写问题，首字母是否大写，人称单复数是否按照要求书写，时态、语态、词性、主谓搭配是否正确，要避免不必要的失分。

47．句意：有一天，陈先生像往常一样来到工作岗位。根据本句的时间状语“one day”，可知本句描述的是过去发生的动作，故用一般过去时态。故答案为arrived。
48．句意：联系上下文，可知此处指的是这两个女孩很震惊。主语是动作的承受者，故用被动语态的形式。缺少过去分词，故答案为shocked。
49．句意：在这一天结束的时候，她们发现了陈先生心情好的原因。短文是在讲述过去发生的故事，从上下文也可以看出句子的时态为一般过去时，故答案为discovered。
50．句意：凯蒂和莎拉认为从现在开始在这个超市工作，生活将要变得好多了。结合语境可知，本句描述的是站在过去角度看将来要发生的动作，故用过去将来时态。答案为would be。
【点睛】由于本题已经给出所需单词，完成比较简单。解答此类题型的方法一般就是根据上下文及时间状语，主语的人称与数，判断出动词的时态和数的变化，然后进行适当的词形变换，完成阅读注意动词，名词等，一般要有词形变化，注意主谓语数的一致问题。而介词则没有词形变化。在叙事性短文中，谓语动词多为一般过去时态及现在完成时态，说明性短文中谓语动词多为一般现在时态。
51．People found Alice the first time in 1989. It was 39 feet long. People were surprised to find that Alice spoke at a different HZ from other whales. No other whales could hear it. It couldn’t find its family and friends. It swam across the Pacific Ocean by itself. It was lucky that Alice seemed healthy. But people lost Alice’s news in 2004. I hope it is still healthy/ it found its family and friends at last/I’m sorry to hear that news.
