Hey. I`m Carl Azuz for CNN STUDENT NEWS. Welcome to our viewers worldwide.

大家好，欢迎全球的观众，我是卡尔·阿祖兹，为您播报CNN学生新闻.

This show`s date is Thursday, September 8. That puts it exactly two months before the 2016 U.S. presidential election.

今天是9月8日,星期二. 还有整整两个月就要进行美国总统选举啦~

Here are the candidates: businessman and TV personality Donald Trump is running on the Republican ticket. Former U.S. Secretary of State Hillary Clinton is running on the Democratic ticket. Businessman and former New Mexico Governor Gary Johnson represents the Libertarian Party. Retired medical doctor, Jill Stein, represents the Green Party

以下是所有的候选者: 共和党候选人商人以及电视名人唐纳德`特朗普,共和党候选人前美国国务卿希拉里`克林顿. 自由党候选人商人和前新墨西哥州州长加里·约翰逊,绿党候选人退休的吉尔斯坦.

There are three presidential debates scheduled starting later this month. They`ll include Mr. Trump and Mrs. Clinton, but at this point, you`re unlikely to see Mr. Johnson or Dr. Stein included. Why? The Commission on Presidential Debates which sponsors and produces the events requires candidates to poll at 15 percent or higher to participate.

计划酱油三次总统辩论于本月底开始.他们是特朗普和希拉里,而你不会看到加里`约翰逊和吉尔斯坦.原因是,赞助和安排总统竞选的委员会要求候选者支持票数必须达到或超过15%才能够参加辩论.

According to the latest CNN/ORC poll conducted early this month, Donald Trump has the lead with the support of 45 percent of likely voters.

根据本月初,最新的CNN/ORC民意调查，唐纳德·特朗普以45%的支持率领先。

Hillary Clinton had the support of 43 percent. Gary Johnson had 7 percent, and Jill Stein had 2 percent.

希拉里·克林顿的支持率为43%.而加里·约翰逊和吉尔斯坦的支持率分别为7%和2%.

OK, next story. Air pollution, it`s well-documented that it can cause lung problems. But can it hurt the human brain. Researchers at Lancaster University in the United Kingdom say yes. They took a look at brain samples from dozens of people who live in polluted areas and they say they found the same kind of particles in the brain that are found in polluted air. They say these particles are toxic. They believe the particles entered the brain when people breathe in polluted air, and they think these pollution particles could increase people`s risk of developing Alzheimer`s disease.

下一则新闻，空气污染。根据记载，空气污染可以引发肺部疾病。同时也会损伤人类大脑。兰卡斯特大学的研究人员对此持肯定态度。他们观看了居住在空气污染地区的数十人的大脑样本。研究人员表示，在这些人的大脑样本中发现了同样一种颗粒。他们称，这些颗粒是有毒的。人们在呼吸有毒气体时，会吸入这些颗粒。同时这些颗粒会增加人类患老年痴呆症的风险。

But there is room for doubt. For one thing, similar particles are produced naturally in the brain and an expert from University College London says any correlation between pollution particles and Alzheimer`s disease is weak. Scientists agree that more research needs to be done on this.

但此种说法尚需证实。首先,大脑也会产生类似的颗粒。同时伦敦大学的专家表示，污染粒子和老年痴呆的联系甚微。科学家们一致认为,还需要进行更多的研究。
