[单项选择]We live in southern California growing grapes, a first generation of vintners, our home adjacent to the vineyards and the winery. It’s a very pretty place, and in order to earn the money to realize our dream of making wine, we worked for many years in a business that demanded several household moves, an incredible amount of risk- taking and long absences from my husband. When it was time, we traded in our old life, cinched up our belts and began the creation of the winery.
We make small amounts of premium wine, and our lives are dictated by the rhythm of nature and the demands of the living vines. The vines start sprouting tiny green tendrils in March and April, and the baby grapes begin to form in miniature, so perfect that they can be dipped in gold to form jewelry. The grapes swell and ripen in early fall, and when their sugar content is at the right level, they are harvested carefully by hand and crushed in small lots. The wine is fermented and tended until it is ready to be b

[单项选择]Attacks on Jose Manuel Barroso, the president of the European Commission, have intensified before the European election held between June 4th and 7th, and ahead of a European Union summit when national leaders will discuss his reappointment to a second five- year term. On the left, the Party of European Socialists (PES) calls Mr. Barroso a conservative who "puts markets before people". Should the PES emerge as the largest group in the European Parliament, it will try to block him.
But prominent federalists are also unimpressed. Guy Verhofstadt, a former Belgian prime minister, speaks for many in Brussels when he denounces Mr. Barroso for a lack of ambition for Europe. Mr. Verhofstadt invokes the memory of Jacques Delors, the pugnacious Frenchman who ran the commission from 1985 to 1995.Mr. Delors proposed many ambitious plans, he says, and got 30% of them: that 30% then became the European internal market. Mr. Verhofstadt thinks that last autumn Mr. Barroso should have proposed s
