When people engage in activities that help others ,their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of wellbeing. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. How ever, that statistic would be what we would expect even if volunteering does not boost longevity, because .

Unlike other mice, mice that are genetically incapable of making these particular cells do not show elevated levels of nitrates when infected with bacteria.The statements above, if true, provide the most support for which of the following conclusions?A. Mice that are unable either to make macrophages or to make them in sufficient numbers will protect themselves from bacterial infections in some other way.B. Mice that show elevated levels of nitrates can easily fight off most types of bacterial infections.C. In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.D. When a healthy mouse bees infected with an invasive organism, the number of macrophages in the mouse’s body decreases.E. Injections of nitrates into mice that lack macrophages will not enhance the ability of these animals’ immune systems to fight off infection.key C, I prefer BMUST BE TRUE題原文給的信息:MICE感染細(xì)菌時(shí),分兩種情況:,N升高(這里理解UNLIKE很重要).特別注意原文沒(méi)有提供信息說(shuō)M在免疫系統(tǒng)起的是何作用,好的,還是壞的.(原文的第一句話很容易被誤解成M對(duì)細(xì)菌起免疫作用).單純這點(diǎn),.答案C來(lái)源于原文第二句話:N和M細(xì)胞的關(guān)系GWD26Q10 Lawmaker: Raising taxes is not the only means of reducing government debt.

The government has no current need for helium. B. Twentyfive percent of the debt the government has accumulated in Stockpiling helium is not an insignificant portion of the government’s Total debt. C. It is not in the lawmaker’s interest to advocate raising taxes as a Means of reducing government debt. D. Attempts to sell the government’s helium will not depress the market Price of helium by more than 25 percent. E. The government will not incur any costs in closing its facilities for stockpiling helium. 答案給的是D,我覺(jué)得應(yīng)該是A2610的BY出現(xiàn)在結(jié)論,是作者得出結(jié)論的前提,.D的取非是:Attempts to sell the government’s helium will depress the market Price of helium by more than 25 percent. 即貶值超過(guò)25%.原來(lái)比債務(wù)高于25%.這樣貶值后就不能全部還債(pay off)考試時(shí)時(shí)間很短,所以不可能很細(xì)計(jì)算,意味著出題人不會(huì)考細(xì)的東西,GWD311616: In recent years, networks of fiberoptic cable have been replacing electrical wire for transmitting telemunications signals.
