【小题3】A
【小题4】C
解析:
这是一篇图表类阅读题。此类短文通常只有少量的文字表述，要求考生依据所提供的图表或描述进行理解。阅读时必须弄清图表中各部件的对应关系，同时针对所设问题进行有目的的识读。
通过观察此图和图中的文字说明，我们可以得知这是一个“自然界中能源消耗流程图”。
【小题1】整体识图题，根据图示和文字说明中的“Energy flows through the system…”一句可得。
【小题2】 细节判断题，根据文字说明“Significance of photosynthesis: it produces food, fuel, fiber and oxygen.”和普通常识可得。
【小题3】细节识图题，此是要弄清图中各部件的对应关系，从“流程”图分析，首先植物接收太阳能，继而为草食动物提供食物，草食动物以为人和肉食动物提供食物，最后都化为腐烂物，为微生物提供食物。认清了这一内在关系，此题的答案就显而易见了。
【小题4】逻辑推理题，从文字说明和图示表面很难找到答案，抓住所设问题中的“…in order to improve the living conditions…”关键词，结合图示下面的粗标题进行分析，树是“producers”，植树多，food, fuel, fiber and oxygen就多，当然生存条件就会更好。
Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide produced by burning of coal, oil, wood, together with industrial pollution, are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere and so raising the temperature of the earth.
The evidence for global warming can now be seen in the world’s changing climate statistics. In Europe, eight of the last ten years have seen record high temperature. For northern Europe, this has generally been a change for the better. Gardens can now even grow tropical plants in England, though London may never see a “White Christmas” again. On the other hand, the countries around the Mediterranean Sea, and those south of the Sahara desert are receiving even less rain than before. In sub-Saharan Africa the crops are drying out in the fields and people are dying of starvation. In the Americans, the climate is becoming more extreme—the summers are getting hotter and the storms are becoming more violent. In 1999 the southern United States was struck by a series of destructive hurricanes, while the end of 1999 saw the worst floods ever in Venezuela. Meteorologists expect such trends to continue, and indeed to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and more extreme weather conditions, scientists are closely monitoring sea levels around the world. These are slowly rising, as the northern and southern polar ice-caps start to melt. This will have serious consequences for low-lying countries near the sea, such as the coral islands in the Pacific, and Bangladesh where the River Ganges already floods the delta（三角洲） every year. Already parts of these places are disappearing under the rising tides.
Title: 71._______________.
he most obvious, but you can come up with as many as you want. Since you are being a detective, you will want to ask lots of questions about your activities in each of these categories. Here you use basic who, what, when, where and how questions to fill in information. For example, “Who did I spend time with?” “Where did I spend the time?” are possible questions that you could ask yourself. When you have finished with the questions you ask, “Now WHY did I spend my time in that way?” The answer to this quwstion is the goal, or at least part of a set of goals that makes you spend your time in that way.
