题目内容

3．I was surprised to find my bag empty after getting off the bus．Someone______everything!（　　）

	A．	had been stealing		B．	had stolen
	C．	have stolen		D．	have been stealing

分析下车后，我很惊讶地发现我的包空了．有人把里面所有东西都偷了．

解答答案：B
该题考查过去完成时用法，由第一句"下车后，我很惊讶地发现我的包空了"可知，该句谓语was surprised使用的是一般过去时，而第二句谓语动作steal应该发生在was surprised之前，所以steal实际是一个表示"过去之过去"的动作，根据英语语法，表示"过去之过去"应用过去完成时，故选B．

点评考查时态时，要注意句中表示时间的成分对时态的提示，如果没有明确的时间提示，则可以通过句中逻辑关系来确定时态．

Stevenson was such a good boxer that people wanted him to turn professional．After he had won his first gold medal，managers and famous promoters started to offer him money to fight around the world．Teofilo turned them all down．He wanted to stay in Cuba and didn't want to fight for money or fame．

11．Developed and developing nations can learn from each other seeking a low-carbon economy，a Chinese government official said in Shanghai yesterday．
China doesn't lag developed nations in terms of energy saving and green economy，said Zhou Changyi，director of the energy saving department of the Ministry of Industry and Information Technology．
"While we can learn many aspects from developed nations，they also should learn something from us，such as water conservation，"Zhou said in a speech during the new Path of China's Industrilization forum at the ongoning China International Industry Fair 2009．
He said industrilized nations and China are dealing with different issues to combat climate change．The United Kingdom，for example，is concerned about transport，buildings and new energy in reducing carbon emmissions．For China，the most urgent task is how to realize new-type of industrilization and avoid mistakes that other countries made when they industrilized．
As such，overseas exhibitors at this year's fair are showing ways to help China achieve low carbon emissions in the industrial section．
Swiss power and automation technology group ABB called for a stronger focus on product life-cycle assesment，or LCA，which is used to study the environmental impact of a product fromthe research  and manufaturing stage through its usage and recycling．

LAC shows that industrial customers should focus on a product's environmental impact throughout its life cycle instead of on its initial investment or ready-to-use stage．For example，a motor's initial investment accounts for only 3percent of its life-cycle cost，while 94percent goes to fuel consumption and the rest to maintenance．
Richard Hausmann，North East Asia CEO of Siemens，said，"The color of future industrilization is green．"
The Germany Company recently announce it wants to receive orders worth more than 6billion Euros （US 8.8billion） for intelligent net power networks，Smart Grid，over the next five years．Siemens has set a 20percent market share target for the global smart grid business．

2．For years we have been dieting strictly after the year-end overeating，afraid that when summer．comes，the bigger size we have accumulated will betray how we ate．Now scientists say，it's a little bug that causes obesity（肥胖）．
As the holiday season with its abundant feasting arrives，millions of food lovers are keeping an eye on their figures．But scientists have found that weight gain is not about too much Christmas turkey or hot chocolates，but some bacteria in your guts（肠）．
Chinese scientists recently discovered a type ofbacteria in guts that may be to blame for obesity．
A research team led by Zhao Liping，a professor in Shanghai，has identified a precise link between a particular kind ofbacteria and unusual weight gain．
"The endotoxin（内毒素） released by the bacterium can activate（激活） a gene that helps produce fat．And it also deactivates a gene that consumes fat，"Zhao says．
Scientists have long believed that microscopic organisms in the gut，microbiota，may play a very important role in weight gain，but they had never been able to prove it．
In 2004，American microbiologist Jeffrey Gordon and his colleagues discovered a general link between obesity and gut microbiota in mice．
While a link was believed to exist，proving it was another matter．
"The list of diseases that they may play a role in is just growing and growing，"says Lita Proctor，director of the US National Institutes of Health．"But the problem is that we're only able to look at associations and aren't yet able to conduct cause-and-effect studies．"
In the clinical study，researchers found a growth of too much endotoxin-producing bacteria，leading t0 35percent ofthe gut bacteria，in an obese patient whose initial weight was 175kg．
Based on this information，researchers tried to cure the patient by feeding him a specialized nutritional liquid food to decrease the bacteria in his guts to ignorable amounts．
After 23 weeks，the patient lost 51.4kg，with his fatty liver disease having almost disappeared．
