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

分析下車后，我很驚訝地發現我的包空了．有人把里面所有東西都偷了．

解答答案：B
該題考查過去完成時用法，由第一句"下車后，我很驚訝地發現我的包空了"可知，該句謂語was surprised使用的是一般過去時，而第二句謂語動作steal應該發生在was surprised之前，所以steal實際是一個表示"過去之過去"的動作，根據英語語法，表示"過去之過去"應用過去完成時，故選B．

點評考查時態時，要注意句中表示時間的成分對時態的提示，如果沒有明確的時間提示，則可以通過句中邏輯關系來確定時態．

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．
Tobias Becker，head of ABB'S process automation division for North Asia and China，said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions．
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．
A smart grid delivers electricity from suppliers to consumers using digital technology，advanced sensors speicialized computers that save energy，reduce costs and increase reliability．The United States and China are considered the two biggest markets for smart grid．

66．"A"can replace the underlined word"lag"．

C．attack              D．fear
67．Which of the following about LCA is correct？B

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（腸）．
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（內毒素） 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．

36．We diet strictly after the year-end overeating becauseD．
A．we won't betray ourselves
B．we eat too much turkey
C．there are bacteria in our guts
D．we don't want to look fat
37．What can be learned from Zhao's research？A
A．Obesity is related to a kind of bacteria．
B．Healthy diet helps reduce your fat．
C．Chocolate doesn't cause weight gain．
D．Too much food leads to overweight．
38．Which of the following statements is TRUE？C
A．Scientists didn't try to find out the cause of overweight．
B．There is a link between mice's overweight and human's．
C．Lita proved the link between bacteria and weight gain．
D．Scientists found bacteria may be related to many diseases．
39．The patient finally lost 51.4kg of his weight afterB．
A.35percent of his gut bacteria were killed
B．the amount of gut bacteria was decreased
C．he had a special kind ofoperation
D．his fatty liver had disappeared
40．What does the passage mainly talk about？C
A．People's eating habits．
