Concrete is probably used more widely than any other substance except water, yet it remains largely unappreciated. "Some people view the 20th century as the atomic age, the space age, the computer age — but an argument can be made that it was the concrete age, " says cement specialist Hendrik Van Oss. "It"s a miracle material." Indeed, more than a ton of concrete is produced each year for every man, woman and child on Earth. Yet concrete is generally ignored outside the engineering world, a victim of its own ubiquity and the industry"s conservative pace of development. Now, thanks to environmental pressures and entrepreneurial innovation, a new generation of concretes is emerging. This high-tech assortment of concrete confections promises to be stronger, lighter, and more environmentally friendly than ever before. Concrete is also a climate-change villain. It is made by mixing water with an aggregate, such as sand or gravel, and cement. Cement is usually made by heating limestone and clay to over 2, 500 degrees F. The resulting chemical reaction, along with fuel burned to heat the kiln, produces between 7% and 10% of global carbon-dioxide emissions. "When we have to repeatedly regenerate these materials because they"re not durable, we release more emissions, " says Victor Li who has created a kind of concrete suffused by synthetic fibers that make it stronger, more durable, and able to bend like a metal. Li"s creation does not require reinforcement, a property shared by other concretes that use chemical additives. Using less water makes concrete stronger, but until the development of plasticizers, it also made concrete sticky, dry, and hard to handle, says Christian Meyer, a civil engineering professor at Columbia University. Making stronger concretes, says Li, allows less to be used, reducing waste and giving architects more freedom. "You can have such futuristic designs if you don"t have to put rebar in there, or structural beams, " says Van Oss. A more directly "green" concrete has been developed by the Australian company TecEco. They add magnesium to their cement, forming a porous concrete that actually scrubs carbon dioxide from the air. While experts agree that these new concretes will someday be widely used, the timetable is uncertain. Concrete companies are responsive to environmental concerns and are always looking to stretch the utility of their product, but the construction industry is slow to change. "When you start monkeying around with materials, the governing bodies, the building departments, are very cautious before they let you use an unproven material," Meyer says. In the next few decades, says Van Oss, building codes will change, opening the way for innovative materials. But while new concretes may be stronger and more durable, they are also more expensive — and whether the tendency of developers and the public to focus on short-term rather than long-term costs will also change is another matter. By saying "a victim of its own ubiquity and the industry"s conservative pace of development"(Line 5-6, Para. 1) , the author means that

A. concrete suffers from its widely application as well as the slow development of building industry.
B. concrete is not appreciated because of its dull color and other drawbacks, with little improvement as a building material.
C. slow progress of building industry does harm to the application and popularity of concrete.
D. concrete is ignored because it is conventional with little advance in its technology.

Charles Darwin wed his cousin Emma and spawned 10 children, including four brilliant scientists. Albert Einstein"s second wife Elsa was his first cousin. Queen Victoria said "I do" to hers. So have millions worldwide. In parts of Saudi Arabia, 39% of all marriages are between first cousins. In the U. S., though, the practice bears a stigma of inbreeding just this side of incest. The taboo is not only social but legislative; 24 states ban the marriage of first cousins: five others allow it only if the couple is unable to bear children. A major reason for this ban is the belief that kids of first cousins are tragically susceptible to serious congenital illnesses. That view may have to change. A comprehensive study published recently in the Journal of Genetic Counseling indicates such children run an only slightly higher risk of significant genetic disorders like congenital heart defects — about two percentage points above the average 3% to 4%. Says the study"s lead author, Robin Bennett, president-elect of the National Society of Genetic Counselors, which funded the study: "Aside from a thorough medical family history, there is no need to offer any genetic testing on the basis of coasanguinity alone. " Publication of the study will do more than tweak public awareness; it will enlighten doctors who have urged cousin couples not to have children. "Just this week, " says Bennett, "I saw a 23-year-old woman who had had a tubal ligation because her parents were cousins and her doctor told her she shouldn"t have children. " The American proscription against cousin marriages grew in the 19th century as wilderness settlers tried to distinguish themselves from the "savage" Indians, says Martin, author of the book Forbidden Relatives: The American Myth of Cousin Marriage. " The truth is that Europeans were marrying their cousins and Native Americans were not. " And doesn"t God have stern words on the subject Christie Smith, 37, a Nevada writer, says she felt guilty when she fell in love with her first cousin"s son Mark. "I was trying so hard to convince myself not to have these feelings, " she recalls, "that I went to the Bible looking for confirmation that it was wrong. And what I found was the exact opposite: support for cousin marriages. " The patriarch Jacob married two of his first cousins, Rachel and Leah. Smith married Mark in 1999. The medical ban is lifted; the social stain may take longer to disappear. It can be inferred from the last paragraph that

A. the ban on cousin marriages is lifted.
B. cousin marriages are permitted again.
C. the prejudice against cousin marriages dies hard.
D. cousin marriages may not be as bad as people think.

A. the traditional building material concrete is the only man-made miracle.
B. concrete is indispensable in the development of modern construction industry.
C. compared with other inventions, concrete is more practical and useful.
