分析 这儿是如此潮湿，以至于树很高，一些高达90米．
解答 答案：A．
考查独立主格结构，the trees are extremely tall是完整的句子，中间没有连词，说明后面是独立主格结构，some是逻辑主语，后面是非谓语动词做状语，measure后面接数词，表示：长，宽，高是多少的时候，measure是不及物动词，用现在分词．选A．
点评 认清独立主格结构的特征，分析句子的结构；最后进行综合判断．

10．
76．B
There are increasing fears of global warming．Consequently，many countries are focusing on the switch to a low carbon economy．This shift will lead to major changes in the supply and use of electricity．To meet these challenges，countries are investing in Smart Grid （智能电网） technology．This system aims to provide the electricity industry with a better understanding of power generation and demand to create a more efficient power network．
77．E
Smart Grid technology basically involves the application of a computer system to the electricity network．The computer system can be used to collect information about supply and demand and improve engineer's ability to manage the system．With better information about electricity demand，the network will be able to increase the amount of electricity delivered per unit generated，leading to potential reductions in fuel needs and carbon emissions （排放）．
78．A
Smart Grid technology is profitable to consumers too．They will be able to collect real-time information on their energy use for each appliance．Varying tariffs （收费标准） throughout the day will give customers the motivation to use appliances at times when supply greatly exceeds （超过） demand，leading to great reductions in bills．
79．F
With these changes comes a range of things to be overcome．The first involves managing the supply and demand．Sources of renewable energy，such as wind，wave and solar，are unpredictable，and nuclear power，which is also set to increase as nations switch to alternative energy sources，is inflexible．A second problem is the fact that many renewable power generation sources are located in remote areas，such as windy uplands and coastal regions．
80．D
Although Smart Technology is still in its infancy，experimental plans to promote and test it are already underway．Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use．Cities are investing money into smart energy，due to the high population density and high energy use．It is here where Smart Technology is likely to be promoted first，making use of a range of sustainable （可持续的） power sources，transport solutions．
| A．The benefit of Smart Grid technology to daily life B．Background for the emerging of Smart Grid technology C．The side-effects Smart Grid technology causes D．People's attitudes towards Smart Grid technology E．The supporting system of Smart Grid technology F．The challenges Smart Grid technology meet with |
