美国有线新闻 CNN 美印第安纳州要求所有高中生参加入籍考试（在线收听）

Who is the Chief Justice of the United States: John Roberts, Mike Pompeo, William Barr or Neil Gorsuch? The Chief Justice, who's also the Chief Judge of the U.S. Supreme Court is John Roberts.

That's a question from the civics part of the U.S. naturalization test. The test that someone born outside the United States takes to become a citizen.

The exam has a total of 100 questions, but only 10 of those are asked to people applying for U.S. citizenship, and they have to get at least six of the answers right.

A new law was just passed in the state of Indiana that requires all high school students there to take the naturalization test as part of their civics studies. They don't have to pass the test to graduate. They just have to take it. Those who support the law say they're concerned that many American high school students wouldn't be able to pass the test. So they're hoping that requiring them to take it will help solve that. Those who oppose the law say it's not necessary since students are already learning this information through their civics, history and social studies classes. The law is set to take effect next school year. Several other states have a similar requirement in place.

Today, we decided to test you knowledge with a few more questions from the naturalization test. First, who is known as the father of our country: George Washington, Benjamin Franklin, John Adams, or Thomas Jefferson? The answer: America's first president, George Washington. Next, what are the first words of the U.S. Constitution? We hold these truths, four score and seven years ago, Congress shall make no law, or we the people? The answer — we the people. Finally, how many U.S. senators are there: 50, 100, 435, or 438? The answer? 100. Two senators for every state.
