Hair loss can be destructive for themillions of men and women who experience it. Now scientists are reporting thata substance from honeybee hives might contain clues for developing a potentialnew therapy. They found that the material, called propolis, encouraged hairgrowth in mice. The study appears in A CS′ Journal of Agricultural and FoodChemistry. Ken Kobayashi and colleagues note that propolis is a resin-likematerial that honeybees use to seal small gaps in their hives. Not only does itwork as a physical barrier, but it also contains active compounds that fightfungal and bacterial invasions. People from ancient times had noticed propolis′special properties and used it to treat tumors, inflammation and wounds. Morerecently, research has shown that the substance promotes the growth of certaincells involved in hair growth though no one had yet tested whether that in turnwould result in new locks. Kobayashi ′ s team wanted to find out.
When the researchers tested propolis onmice that had been shaved or waxed, the mice that received the treatment regrewtheir fur faster than those that didn′t. The scientists also noticed that afterthe topical application, the number of special cells involved in the process ofgrowing hair increased. Although they tried the material on mice that couldgrow fur rather than balding mice, the researchers note that hair lossconditions often result from abnormal inflammation. Propolis contains anti-inflammatorycompounds, so they expert it could help treat balding conditions.
They add that further testing is needed tosee if the beehive material affects human hair follicles.
What′s the main idea of the passage?

根据以下材料，回答
The American Revolution was not arevolution in the sense of a radical or total change. It was not a sudden andviolent overturning of the political and social framework, such as lateroccurred in France and Russia, when both were already independent nations.Significant changes were ushered in, but they were not breathtaking. Whathappened was accelerated evolution rather than outright revolution. During theconflict itself people went on working and praying, marrying and playing. Mostof them were not seriously disturbed by the actual fighting, and many of themore isolated communities scarcely knew that a war was on.
America′s War of Independence heralded thebirth of three modem nations. One was Canada, which received its first largeinflux of English-speaking population from the thousands of loyalists who fledthere from the United States. Another was Australia, which became a penalcolony now that America was no longer available for prisoners and debtors. Thethird new comer--the United States--based itself squarely on republican principles.
Yet even the political overturn was not asrevolutionary as one might suppose. In some states, notable Connecticut andRhode Island, the war largely ratified a colonial self-rule alreadyexisting.British officials, everywhere ousted, were replaced by a home-growngoverning class, which promptly sought a local substitute for king andParliament.
What will the paragraph following thepassage most probably discuss?

本题解析：
主旨题。通读全文可知，文章的结构是总一分结构。第一段是总括段，第二、三段是分段。根据第一段中“The American Revolution was not a revolution in the sense of aradical or total change．”“Significant changes wereushered in，but they were not breathtaking．What happened was accelerated evolution rather than outrightrevolution．"可知美国革命并未导致完全的和彻底的变化，所发生的只是进化的加速，并不算是一场革命。所以D项“美国革命：进化而不是革命”作为文章标题最恰当。

There are two types of people in thisworld: those who regularly wash their office coffee cup. And those who only takeit off their desk to cover up the coffee mark at the bottom with a fresh pour, drivingaway their shame with the reasoning that the heat must kill the bacteria orspine thing.
Depending on which type of person you are,this will be either mildly annoying or more-than-mildly exciting. As HeidiMitchell wrote in a recent Wall Street Journal column, it′ s fine to never washyour cup, as long as you′ re not sharing it with anybody else.
There are two warnings to that statement,infectious-disease expert Jeffrey Strake, a professor at Baylor College ofMedicine, told Mitchell; One, it only applies if you′re not sharing the cupwith anybody else. And two, if you leave cream or sugar in your cup over theweekend, that can certainly cause mold(霉) to grow--in which case, wash it out.
Otherwise, though, there′s not really muchto worry about. "If I went and cultured the average unwashed coffee cup,of course I would find bacteria." Starke said. "But remember the vastmajority came from the person who used the cup." Even if you drink from itwhile sick, it′s pretty hard to re-infect yourself with the same cup; mostviruses don′t live long outside the body, which means that just letting yourcup live in its own dirt may be a safer bet than the alternative; cleaning it withthe disgusting sponge (海绵) in theoffice kitchen "The sponge in the break room probably has the highestbacteria count of anything in the office." Starke said if the idea of notwashing horrifies you, just stick the sponge in the microwave before using.Otherwise, though, reel free to continue your lazy ways without guilt.
Where does the passage probably comefrom?
