Less than three weeks away from the U.S. midterm elections, we are exploring what exactly Americans will be voting for. First up today on CNN STUDENT NEWS. Five things to know about the midterms.

距离美国国会中期选举还有不到三周的时间，我们非常期待美国人将会做出怎样的投票。这是今天 CNN学生新闻的首条新闻，关于中期选举有五点需要注意。

One, they are called midterms because they happen in the middle of a president`s four year term. So, voters aren`t choosing a president this year.

第一，之所以称为中期选举是因为举行时间发生在总统任命四年中的中途时间。所以今年选民您不会对总统进行投票。

They are choosing their representatives in Congress as well as many local and state offices.

他们会选举当地或者州政府办公室工作人员作为其国会代表。

Two, the U.S. House of Representatives elected officials serve two-year terms. That means, all of the chambers` 435 seats are up for election this year.

第二，美国众议院当选官员有两年任期，也就意味着今年所有435个议员席位都将进行投票选举。

Three, Republicans currently control the House by a significant majority. They are expected to stay in control after this year`s midterms.

第三，目前共和党人占众议院的大多数比重。在今年的中期选举之后预计仍将继续任职。

Four, the U.S. Senate. Elected officials there serve six year terms, so about a third of the chambers` 100 seats are up for election.

第四，美国参议院。当选官员每六年一选，所以100名议员中三分之一的席位将会进行选举。

Democrats currently control the Senate, but by a slim majority.

目前民主党占参议院大多数，不过仅有微弱比重之差。

So, five, many analysts are saying Republicans have a good chance of taking Senate control this fall. The date of the vote, November 4. Next today, we`ve heard from the nurse at a hospital in Dallas, Texas, who apparently caught the Ebola virus from the victim she was treating.

第五，许多分析家认为共和党人在今年选举中有很好的机会可以很好控制参议院。投票日期为十一月四日。今天的第二条新闻说的是德克萨斯达拉斯一家医院感染埃博拉病毒的护士。

26-year old Nina Pham says she`s doing well and thanks everyone for their kind wishes and prayers.

26岁的Nina Pham称目前身体条件良好，并感谢所有人的帮助和祝愿。

She also says she`s blessed by the support of family, friends and the care of doctors and nurses at the hospital.

她还表示收到了来自家庭，朋友和医院护士，医生朋友的美好祝愿。

Pham also received a blood transfusion from American Ebola survivor, Dr. Kent Brantly. It`s possible that antibodies from a survivor`s blood could help someone else with the disease.

Nina Pham已经受到了来自美国埃博拉治愈患者Kent Brantly博士的血清抗体。或许治愈者体内的血清抗体可以帮助她对抗体内的埃博拉病毒。

According to the World Health Organization, almost 9,000 cases of Ebola have been reported. Mostly in West Africa. About half of those people have died.

根据世界卫生组织发布的消息称全世界已经发现9000例埃博拉病例，大多数发生在西非国家。其中大约有一半的患者已经死亡。

The World Health Organization expects that by December between 5,000 and 10,000 new cases will be reported every week in West Africa.

世界卫生组织预计到十二月西非国家每周埃博拉患者将会达到五千到一万例新增病例。

In the U.S., the CDC is preparing an emergency response team, that it says can be at any American hospital within hours to help treat Ebola and prevent it from spreading.

在美国，疾病预防与控制中心正在准备一支应急小组，称将会在发现埃博拉病例后几小时内到达该医院协助救治并防止病毒传播。
