[单项选择]A Nation That’s Losing Its Toolbox
The scene inside the Home Depot on Weyman Avenue here would give the old-time American craftsman pause.
In Aisle 34 is precut plastic flooring, the glue already in place. In Aisle 26 are prefabricated windows. Stacked near the checkout counters, and as colorful as a Fisher-Price toy, is a not-so-serious-looking power tool: a battery-operated saw-and-drill combination. And if you don’t want to do it yourself, head to Aisle 23 or Aisle 35, where a help desk will arrange for an installer.
It’s all very handy stuff, I guess, a convenient way to be a do-it-yourselfer without being all that good with tools. But at a time when the American factory seems to be a shrinking presence, and when good manufacturing jobs have vanished, perhaps never to return, there is something deeply troubling about this dilution of American craftsmanship.

[简答题]Asians see the United States losing its undisputed international influence in 50 years to possibly China amid waning trust in Washington to act responsibly in the world, a poll showed. The study is carried out by the Chicago Council on Global Affairs (CCGA), an independent US think tank. In the immediate term, US power in the eyes of Asians remains secure. In haft a century, however, a majority in all countries covered by the poll—China, India, South Korea and the United States—believed "another nation" will become as powerful or surpass the United States in power. China has become a global manufacturing power and is already displacing the United States as the primary trading partner for many nations. China has also amassed the world’s largest trade surplus and world’s largest foreign exchange reserves.

THE CIRCULATORY SYSTEM OF TREES
1 Inside the tree’s protective outer bark is the circulatory system, consisting of two cellular pipelines that transport water, mineral nutrients, and other organic substances to all living tissues of the tree. One pipeline, called the xylem--or sapwood--transports water and nutrients up from the roots to the leaves. The other, the phloem--or inner bark---carries the downward flow of foodstuffs from the leaves to the branches, trunk, and roots. Between these two pipelines is the vascular cambium, a single--cell layer too thin to be seen by the naked eye. This is the tree’s major growth organ, responsible for the outward widening of the trunk, branches, twigs, and roots. During each growing season, the vascular cambium produces new phloem cells on its outer surface and new xylem cells on its inner surface.
