题文
In 2008 and 2009 I published two articles researching a lull (停歇)in solar activity. At the time, thereappeared to be some disagreement among scientists as to what effect this might have on humancaused
global warming. Now climate scientists agree a less active sun won't have much of an effect.
According to the reports from the IPCC, global climate is expected to warm between 4 and 10
degrees Fahrenheit by the year 2100. On the other hand, scientists show that the reduction in radioactive
forcing due to low solar activity would reduce world temperature half a degree F if the lull in solar activity
lasted until the end of the 21 century.
It is highly unlikely the current lull in solar activity would have such a long period. "It is more likely that a new lull in solar activity would reduce the global temperature average of 0.2 Celsius by the end of
2100," commented Professor Stefan Rahmstorf, who was responsible for a study of a lull in solar activity
effects on climate at the Institute for Research on the Impacts of Climate Change in Potsdam.
In short, this small forcing is likely to have little, if any, observable effect on humancaused global
warming,at most reducing the temperature increase to between 3.5 and 9.5 degrees F. The reason for
the small effect on temperature is due to the fact that the difference between solar activity highs and lows
changes solar output by less than one half of one percent. So the difference in the amount of energy
coming out of the sun between solar highs and lows isn't very large. The result is that the human forcing
on climate is many times larger than that caused by any natural difference in the sun.
Generally if humancaused climate_change isn't controlled it can't be stopped by natural changes in the
sun.1. What once caused the argument among scientists?A. The reduction in world temperature.
B. That humans are responsible for global warming.
C. That humans are stronger than nature.
D. Whether the lull in solar activity has effect on humancaused global warming.2. According to scientists, world temperature would fall a little if ________.A. less CO2 is given off
B. more trees are planted
C. redioactive forcing becomes strong
D. the lull in solar activity lasts a long period3. What can we learn from the passage?A. The author is expert at writing science fiction.
B. The current lull in solar activity will last very long.
C. The power of humans is stronger than the sun on global warming.
D. The IPCC reported that world temperature would fall greatly.4. What do the underlined words "climate change" refer to?A. The flood.
B. Global warming.
C. The earthquake.
D. Global environmental change.5. What does the passage mainly talk about?A. The effect of global warming.
B. An argument among scientists.
C. That humans are a cause of global warming.
D. That a less active sun cannot stop global warming.6. 用30词左右概括文章大意________________________________________________________________________

考点
据考高分专家说，试题“ In 2008 and 2009.....”主要考查你对 [日常生活类阅读 ]考点的理解。日常生活类阅读
日常生活类阅读的概念：
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。
日常生活类阅读题答题技巧：
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
