美国总统候选人辩论话题揭晓

The moderator of the first presidential debate next Monday has revealed the three topics to be discussed by presidential candidates Democrat Hillary Clinton and Republican Donald Trump.

The debate will consist of two 15-minute segments for each of these three topics: America's direction, achieving prosperity and securing America.

Moderator Lester Holt, host of “NBC Nightly News,” will open each segment with a question, after which each candidate will have two minutes to respond. Candidates also will have the opportunity to respond to each other.

Third-party candidates Jill Stein of the Green Party and Libertarian Gary Johnson were not invited to the debate because they did not reach the required threshold of support by averaging at least 15 percent in five public opinion polls the Commission on Presidential Debates selected last month.
