Paraphrasing (2nd paragraph)

Text

The U.S. Government supports EU enlargement as a means to build stability and cooperation across the European continent. U.S. companies are likely to benefit from reduced transaction costs resulting from the harmonization of standards and other regulations for doing business; for example, a single tariff schedule and one set of trade rules across Europe. U.S. exports to the candidate countries should face lower tariffs on accession, since the EU's common external tariff is generally lower than the tariffs currently applied by the candidates. In addition, opportunities for U.S. investment will expand as the candidates undertake economic reforms, create attractive financial markets, strive to improve firms' competitiveness, and adopt the EU's open and transparent investment regime.

The main idea of the paragraph

After the enlargement, the U.S. businesses are also likely to benefit from improved business and investment environments resulting from economic reforms and from the adoption of the E.U. standards and other regulations.

在扩盟后,由于实施经济改革和采纳欧盟的标准以及一些其它的规则,经商和投资环境会有所改善,从中美国的企业也可以受益。
