The trees appear to have faster growth rates due to longer growing seasons and higher concentrations (浓度) of carbon dioxide in the ___41___. 本题，the 后面的单词肯定得是个名词呀。上面给出的名词有哪些？就算把动名词也算上无外乎就是B,E,J这三个选项，这里面选E不会错。从意思上来说，什么什么当中更高的二氧二碳浓度呢？二氧化碳当然是在空气当中的了！本题可解！ 例句： He looks older now than when he took the office. 他比刚当选时老多了。 A lot of people got killed as a result of your mistake. 因为你的错误，很多人没命了。 Due to His success was largely due to luck His success was largely due to his hard work. 他的成功主要是由于运气。 Geoffrey Parker, a scientist at the Smithsonian Environmental Research Centre in Edgewater. Maryland,(这种较长的人物介绍插入语在科技说明文当中特别多。要能看习惯，因为这在雅思考试当中很可能成为出题点) said that the increase of the rate of growth was unexpected and might be ___42___ to the higher temperatures and longer growing seasons documented in the region. 42题，这时面首先要知道这是一个固定搭配，是be ( )to 结构。而这个结构连结的前后二个部份分别是生长率的增长和高温及更长的生长季之间的关系。而它们之间的关系恰恰在第一段的最后一句话已经给出，那就是一个因果关系。所以应该知道这里要填的固定搭配是一个因果关系，一个正向关联关系。G选项为惟一可选项。与……相配，相适应，相对应。 Match something to someone/something It is vital to match the software to the task. 让软件与任务相配很重要。 The software should be matched to the task. The growth may also be influenced by the significant ___43___ in atmospheric CO2, he said. 此处对于第41题是重要提示。 43题先可知一定是个名词，而这个名词的意思不用说了肯定是增加，为什么？因为第一段的最后一句话。 读到这里，我们知道这篇题目的模式了。通过大致的判断词性，在本文当中找到相对应的文义然后进行词语替换就可以了。正如我们说过老外写文章的习惯一样，他们通常是先用一句话或一小段把整篇文章交代一遍，然后再用更长的篇幅把这一句话或这一小段话再说一遍，但是这一次就说得要具体，详细。说白了，有一种先说主题然后进行扩写的意味！这篇文章，读懂是第一位的！ "We made a list of reasons these forests could be growing faster and then excluded half of them," Dr. Parker said. Their study suggests that northern forests may become increasingly important in ___44___ the influence of man-made CO2 on the climate. 44题，后面肯定应该填个名词，但是这后面又象是跟着个宾词似的。这是典型的动名词形式。如果这样看费劲，就换种思路。把这句话带着空格翻译出来。你问问自己空格上汉语你想填什么？不就是抵消，减缓吗？这个意思应该是生都能明白的！ Dr. Parker and his colleagues have ___45___ out 这个地方好象是个固定搭配吧。首先，前面出现了have,这是一个边远 成时的标志。后面肯定是done形式。合条件的只有D,E,I三个了。应该都知道carry out吧。意思为施行，实施a detailed record of the trees on a(n) ___46___ basis since 1987. 46题肯定是填一个形容词了。在……的基础上。看一看上面给出的形容词A,C,可知！ They calculated that due to the global warming the forest is producing ___47___ tons of wood each year.刚看完形容词就又出形容词的题，太没技术含量了吧！填增多的，额外的。意思上也合适，本文说了半天就是天热了树就长得快，长得快可不就是木材多了！ The scientists ___48___ the land with trees at different stages of growth and found that both young and old trees were showing increased growth rate. 48一定是个动词。而且还得是个did形式。只有D，E二个选项可选，很容易了！ More than 90 per cent of the tree groups had grown by between two and four times faster than the scientists had ___49___ from estimates of the long-term rates of growth. 本题一看就是要填个动词的done形式。太简单了。只有一个选项可选了！ 本篇题目的题型有一点点象雅思考试中阅读里面的词库填空。而这类型题对于中国学生来说也是最头疼的。 不过要让我说，这题出得算是相当厚道了。为什么？因为人家已经把单词的适当形式给你写好了！如果要是让你用给出单词的适当形式填空，那难度又加深一层！所以这里要提醒考生的是：一定要注意审题。题目中没有要求再变换单词形式的，要跟自己说，这意味着从单词的形式上就可以找到一些蛛丝马迹！ 单词的形式在这里无外乎就是词性。词性上就可以将一些题直接缩小范围！ 这道题看起来很吓人，其实无外乎是把科技说明文变了个形式而已。通过对完整部分精读特别是第一段信息精读基本搞清楚文章的大意对于做这道题十分重要。搞清楚整篇文章讲的是什么，里面涉及了哪些因素，其中的关系是什么，这篇文章就变得很简单了。 词性搞清楚，词义弄明白，整篇文章大意确定。这就是本题的基本要求。 这篇题目考精读，考读明白，考读懂，对于应付高考题有很重要的指导意义！
