8、untainswhich are needed for a ski area are the two things that cause avalanches(雪崩), large mass of snow and ice crushing down the side of a mountainoften called “White Death.”It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. H
9、e first started on avalanche control work in the winter of 193738 at Alta, Utah, in Wasatch National Forest.This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches bef
10、ore it became a major ski area. Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps(团队)of snow rangers.It takes many things to make a snow ranger. The snow ranger must be in excel

He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better.He studies snow, terrain, wind, and weather. He learns the conditions that produce
12、 avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery(炮), by blasting with TNT, and by the difficult and skillful art of skiing avalanches down.The snow ranger, dressed
13、in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger(扳机) on a 75 mm. Recoilless rifle(无后坐力步枪), skis waist deep in powder testing snow stability, or talks with the ski areas operator as he goes about his work to protect the public from

20、ratitude education is the first lesson of the life education and safety education launched by the Ministry of Education. We receive it because_Thank you for listening!答案课时作业(四十).1.D考查动词的时态。根据句中的时间状语all the time可知，科学家们一直在创造奇迹，因此应该使用现在完成进行时。2B句意：很高兴可以看到那些除了痛苦和饥饿便一无所有的成千上万的人们有机会改善他们的生存条件。本题宾语从句的主语是mill
21、ions，而who had nothing but a record of misery and hungry是修饰millions的，故选择B项。3D考查动词的时态。注意说话的时间为现在，把“MP5带来”这一动作发生在过去并对现在造成了影响，因此用现在完成时。4A考查动词的时态。从后面的and now可以看出，“李小姐在公司做了5年秘书”这件事情发生在过去，现在她已经不是秘书了。据此判断这一动作发生在过去，应该用一般过去时。5D考查动词的时态。语境表示“你当时没注意听”，据此判断“注意”是过去某时正在进行的动作，故应用过去进行时。6B考查倒装。句意：只有双方都接受了协议，在这个地区才能建立持
22、久的和平。only if “只有”，引导的状语从句置于句首时，主句的主谓采用部分倒装结构。if only“要是就好了”，从句用虚拟语气，表示与事实相反的情况；as long as “只要”，表示条件；unless “除非，如果不”。7B考查虚拟语气。if only但愿，要是就好了。下句意为：要是我没对他说那些严厉的话就好了。和过去事实相反，故用过去完成时。8C考查情态动词表猜测的用法。答句句意：他不可能走远，因为他的外套还在这里。故选C。9C考查非谓语动词。take measures to do sth.采取措施做某事，其被动形式为measures have been taken to do
23、sth.。10B考查名词辨析。根据句意，空格处应填入一个名词构成表示“使我们感到放心”之意的介词短语。因此正确答案为B。anxiety 意为“焦虑”； view 意为“观点”； judgment 意为“判断”。句意：使我们松了一口气的是，杰弗里的病并没有像我们所担心的那样严重。11C考查交际用语。A项意为“这是我的职责”； B项“在这一点上我赞同你”；C项“不客气”，用于回答感谢；D项“这样说太好了”。由Thanks so much for everything.可知选择C项。12C考查冠词用法。in preparation for是固定搭配，意思是“为做准备”。 knowledge 常用作不
24、可数名词，意为“知识”，但也可以用作可数名词，只作为单数，这个形式用法单一，即a/an(形容词)knowledge，表示一种特定的知识。13B考查定语从句。代替表抽象地点的 accident在从句中作状语，所以要用 in which in the accident。句意：教育部发表声明说，屡屡发生的校园内学生遇袭事件已经为校园安全敲响了警钟。14C考查非谓语动词。assuming具有连词功能，意为“假设”。15C考查副词辨析。meanwhile “同时，其间”。句意：下一趟公共汽车20分钟后才到，其间让我们去那里喝杯咖啡吧。somehow “以某种方式”；anyway “不论如何，不管怎样”；
25、 therefore “因此”。.本文简述了雪地管理员的职业特点、职责以及他们惊险刺激的生活。同时，文章也告诉我们什么样的人才能成为一个真正的雪地管理员。16A细节理解题。从第三段中The Forest Service set out to do it, and did, with its corps of snow rangers可知，森林服务部和它的护雪场工作人员队伍一起着手做这件事(指控制雪崩)并且做到了。所以答案是A。17D细节理解题。从文章第四段的首句It takes many things to make a snow ranger.及He must be a good skier
26、 and a skilled mountain climber.可知，雪地管理员应是优秀的登山运动员。18C推理判断题。从文章第五段He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. 可知，雪地管理员使用有很强杀伤力的枪其目
27、的在于制造雪崩使雪崩沿着山坡轰隆隆地滚下。19B推理判断题。从文章第五段He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength可知，雪地管理员的职责应是预测天气和控制雪崩。20C推理判断题。A项“知道怎样使用手枪”， 文章中提到了“枪”的使用，所以A不是推理；B项“必须写有关其工作的长篇报告”；C项“值班时可能会滑行数英里”；D项“工作时间很长”。依据常识和已有的对文章的了解推断C最合理，因为第四段中说“雪地管理员”
28、必须是身体素质好，所以暗示答案为C。.Dear Mr Black，Were very to have received your money and some reading materials.Thank you very much.We been studying hard since we came back to school. the help of our teachers and classmates，we have made great progress our studies .So we often praised and encouraged by our teacher
29、s and parents.We have made up our minds to study than before to learn every subject well in order to be admitted to key in the future.Were looking forward to you，but we have no chance to go to theKG1.5mmNanjing ourselves.So we hope you can post us a photo of soon.Best wishes!Yours，Li Hua.在系动词后作表语，用形
30、容词形式。 从句若用since 过去时，主句则用现在完成时。 with the help of sb.为固定短语，意为：在某人的帮助下。 在某个方面，用介词in。 我们是被老师鼓励和表扬的，所以用被动语态。 后面有表示比较的than，所以用比较级。 这里泛指各类重点大学。 在look forward to短语中，to为介词，后面要跟动名词形式。 Nanjing是专有名词不加冠词。 前面有表限定的of，意为“的”。所以后面应该用人称代词，意为“你的一张照片”。.One possible version：Good morning, everyone!Gratitude education is t
