请各位朋友们用英文Give a short description of how the U.S government

刚好我在看UK和US的policy。下面就是书上对美国法律产生的一个介绍,1,A law begins as a proposal called a "bill"。2,it is read,studied in committees,commented on and amended in the Senate or House chamber in which it was introduced。3,it is then voted upon。4,if it passes,it is sent to the other house where a similar procedure occurs。Members of both houses work together in "conference committees"if the chambers have passed different versions of the same bill。5,when both houses of Congress pass a bill on which they agree,it is sent to the president for his signature。Only after it is signed dose the bill become a law!Another thing,the president has the power to veto it and the Supreme Court has the power to declare a law unconstitutional and therefore no longer in effect when it is challenged in the courts as unconstitutional。希望对你有用,
