阅读下面材料，回答134～137题。

材料一：2007年以来，我国的消费品价格呈现出较快上涨的趋势，前10个月累计，居民消费价格((CPI)同比上涨4.4%，8至10月份分别上涨了6.5%、6.2%和6.5%，其中食品类及居住类价格上涨较多。尽管当前我国的核心CPI(即CPI数据中剔除食品和能源价格的部分)上涨并不高，但由于我国是一个发展中国家，恩格尔系数较高(2006年我国农村恩格尔系数为43%)，因此近期物价的上涨对低收入阶层和困难群众的生活影响较大。除了CPI上涨较快之外．当前我国股市和楼市等资产市场价格也在高位上运行，2008年10月份全国70个大中城市房屋销售价格同比上涨了9.5%。
材料二：典型的通货膨胀，应该是非食品价格在加速全面上涨，同时，经济增长越快的地区通胀率越高。而目前我国的此轮物价上涨的根本动力来自于食品价格的剧烈变动，同时，经济增长快的区域，物价增长较慢，相反，经济增长慢的区域，物价涨幅较大。
此外，我国此轮价格上涨也包含着价格结构的合理调整，也就是此轮物价上涨是由于农产品和其他资源、要素价格的合理回归(或市场矫正)而引起的。这与货币供应量发行过多而引起的货币贬值过程明显不同。
2007年经济增长率和物价上涨率均创本轮经济周期以来的新高，正因如此，中央经济工作会议提出“两防”目标，即防止经济出现全面过热及防止出现明显的通货膨胀。

“两防”是指( )。

A．防止经济增长过快

B．防止经济增长由偏快转为过热

C．防止价格由结构性上涨演变为明显通货膨胀

D．防止价格结构性上涨

Imagine eating everything delicious you want with none of the fat. That would be great, wouldn’t it

New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate fat from certain foods. Critics, however, say the new compound can rob the body of essential vitamins and nutrients and also cause unpleasant side effects in some people. So it’s up to consumers to decide whether the new fat-free products taste good enough to keep eating.

Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.

Normally, special chemicals in the intestines (肠道) "grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.

The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.

Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fit substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E and K from being absorbed. It can also prevent the absorption of carotenoids (类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.

Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.

Olestra is different from ordinary fats in that （）。

A. it facilitates the absorption of vitamins by the body

B. it passes through the intestines without being absorbed

C. it helps reduce the incidence of heart disease

D. it prevents excessive intake of vitamins
