第1题：
根据题目要求完成下列任务。用中文作答。
阅读所给材料，回答下列三个问题：
(1)这两份材料分别属于哪种语篇类型?(6分)
(2)这两份材料分别适合于哪种课堂教学?说明理由(至少写出两个要点)。(12分)
(3)分析教师选用文本材料时需要考虑的基本要素(至少写出三个要点)。(12分)
材料1
Tom: Hello Alice. I'm interested in your work saving birds! What do you think is the most difficult part of your work?
Alice: Well ... I suppose it's saving wild birds covered in oil. That's the most difficult of all.
Tom: How does that happen?
Alice: The oil comes from boats. It floats on the water and covers the bird's feathers when they swim through it.
Tom: That sounds terrible. What do you do about it?
Alice: The first thing we do is to make sure the bird hasn't tried to clean itself with its beak.
As it does so, the bird eats some oil and becomes sick.
Tom: Oh dear! Do the birds always die?
Alice: Sometimes ... but we try to save them. Birds use their feathers like a raincoat to keep out cold water. When feathers are covered in oil, they stick together and a bird's skin gets cold in the water. So without help the bird would die of cold!
材料2
Scientists have discovered that when chimpanzees have stomach pains, typically because of intestinal parasites, they look for a certain plant to eat, Lippea. It is common in the jungles where chimpanzees live, and it contains chemical substances effective against many parasites.
Lippea is not the only natural medicine in the chimpanzees' cabinet. They may actually use up to thirty different plants--for different problems. Interestingly, the local people make use of many of the same plants for medical purposes. It is almost certain that chimpanzees discovered these herbal remedies before humans.答案：解析：(1)语篇指的是实际使用的语言单位，是一次交际过程中的一系列连续的语段或句子所构成的语言整体。
根据韩礼德的观点，语篇是一个语义单位或意义潜势的现实化．任何一个口头或书面语言片段，不论其长短，只要能构成一个语义整体，即表达完整的意思．就可以称之为语篇。语篇之所以重要．是由于它是交际过程中传递(口头或书面的)信息的语言形式：根据语篇的概念，第一篇属于会话语篇，第二篇属于段落语篇。
(2)第一篇适合口语教学．第二篇适合阅读教学。
理由：①第一篇语言比较简单，没有生僻词汇，句式偏向口语化，适合用于口语练习；第二篇语言偏向书面化，词汇相对较复杂，并且多了长难句，适合进行句子的分析，因此适合阅读教学。②第一篇偏向生活化，有生活气息．适合平时与人交际使用．英语口语的最终目的就是让学生达到沟通交流．因此会话语篇可以提供这样一个交流的环境。第二篇偏向说明性语言，是补充介绍知识的．因此可以作为阅读材料来使学生在知识层面有所丰富和提高．同时也加强了语言理解方面的训练。
(3)需要考虑的基本要素：
①教学内容要素
教学内容是要完成的教学任务，是实现教学目标的主要载体。因此教师在选择材料时．需将教科书作为主要依据。教材分析基本关注教学的重点、难点及考点方面。比较注重显性教材的运用而忽视隐性教材的挖掘和利用，较少关注与学习教材内容有密切关系的认知和心理因素．以及教材对学生能力的要求，而对教学的重点和难点也只是阐述其内容，没有做进一步的分析。在新课改背景下，教学内容分析既要有对显性教材的运用，也要有对隐性教材的挖掘和利用。
⑦教学对象要素
学生是分析教学任务必须要考虑的因素．分析学生是为了帮助学生解决学习中的困难．完成教学任务。教师应该做到以下两点：一是要了解教学活动开始前学生在认知、情感、态度等方面已经达到了什么样的水平，这一水平标志着学生已经能做什么，说什么，想明白了什么等(即学生的学情)。这是学生掌握新的学习任务的起点水平。二是要了解教授了教学材料后预期学生在认知、情感、态度等方面必须达到的状态。对这种状态的把握最终会转化为确定的教学任务与具体的学习目标。只有当教师的心中对教学前和教学后这两种状态的差距做到心中有数时。才能根据学生的实际情况，确定恰当的教学内容。
③教学目标要素
教学目标是教育者在教学过程中，希望受教育者达到的要求或产生的变化结果，也是教师完成教学任务的归宿。新课程标准从关注学生的学习出发，强调学生是学习的主体，教学目标是教学活动中师生共同追求的，而不是由教师所操纵的。因此，教学目标的主体显然应该是学生。教师在选择教学材料的同时也要以学生为出发点．思考需要完成怎样的教学目标或达到怎样的教学效果。 -

第3题：
An Essential Scientific Process
All life on the earth depends upon green plants. Using sunlight, theplants produce their own food. Then animals feed upon the plants. They take inthe nutrients the plants have made sted. But that’s not all.Sunlight also helps a plant produce oxygen. Some of the oxygen is used by theplant, but a plant usually produces me oxygen than it uses. The excess oxygenis necessary f animals other ganisms to live.
The process of changing light into food oxygen is calledphotosynthesis. Besides light energy from the sun, plants also use water carbon dioxide. The water gets to the plant through its roots. The carbondioxide enters the leaves through tiny openings called stomata. The carbondioxide travels to chloplasts, special cells in the bodies of green plants.This is photosynthesis takes place. Chloplasts contain the chlophyllsthat give plants their green col. The chlophylls are the molecules thattrap light energy. The trapped light energy changes water carbon dioxide toproduce oxygen a simple sugar called glucose.
Carbon dioxide oxygen move into out of the stomata. Watervap also moves out of the stomata. Me than 90 percent of water a planttakes in through its roots escapes through the stomata. During the daytime, thestomata of most plants are open. This allows carbon dioxide to enter the leavesf photosynthesis. As night falls, carbon dioxide is not needed. The stomataof most plants close. Water loss stops.
If photosynthesis ceased, there would be little food other ganicmatter on the earth. Most ganisms would disappear. The earth’s atmospherewould no longer contain oxygen. Photosynthesis is essential f life on ourplanet.
词汇：
nutrient n.营养物
ganism n.生物体，有机体
carbon dioxide n.二氧化碳
chloplast n.叶绿体
molecule n.分子
vap n.水蒸气
oxygen n.氧气
photosynthesis n.光合作用
chlophyll n.叶绿素
glucose n.葡萄糖
cease v.停止

5.Another good title f this passage would be
A.Oxygen Carbon Dioxide.
B.Plants Their Roots.
C.How Photosynthesis Wks.

C.green.
D.liquid.答案：B解析：1.B 前文讲到，植物产生的氧气一部分被植物自身消耗了，但植物消耗的氧气量远小于它们产生的氧气，因此可以推测这句话的意思应该是剩余的氧气对于动物以及其他生物体的生存是至关重要的。excess在句中的意思是“超额的”，与extra“额外的”意思相近。 -
