A.以心脑血管病、恶性肿瘤为主
B.以传染病、寄生虫病为主
C.从传染病向非传染病过渡
D.从慢性非传染性疾病向慢性传染性疾病转变

答案

参考答案:C

解析: 由于各地社会经济发展和自然历史条件的制约,我国人群健康状况存在明显的地区差异,大体可以分为三类:第一类:发达型,主要分布在大城市和沿海经济发达地区,其健康状况、疾病谱和死因谱已接近发达国家。心脑血管疾病、恶性肿瘤、意外死亡及由不良生活方式和行为引起的疾病已成为最主要的死因。第二类:发展型,主要分布在中小城市和大部分农村地区,主要死亡原因处于从传染性疾病向心脑血管疾病、恶性肿瘤的转型期。第三类:欠发达型,主要分布在一些经济欠发达的农村、边远地区、山区和少数民族聚居区。传染病、寄生虫病和营养不良性疾病仍然有相当高的死亡率。

President Obama: I want to welcome Vice President Xi to the Oval Office and welcome him to the United States. This is obviously a great opportunity for us to build on the U. S.-China relationship, but also an opportunity to return the extraordinary hospitality that Vice President Xi showed Vice President Biden during his recent visit to China.

As I indicated during my recent visit to APEC and the East Asia Summit, the United States is a Pacific nation. And we are very interested and very focused on continuing to strengthen our relationships, to enhance our trade and our commerce, and make sure that we are a strong and effective partner with the Asia Pacific region. And obviously, in order to do that, it is absolutely vital that we have a strong relationship with China.

So, Mr. Vice President, I hope you have a wonderful visit while you're here. I'm sure the American people welcome you. I'm glad that you're going to get an opportunity to get out of Washington. I know you'll be visiting Lowa, which you visited many years ago when you were governor. And I understand you're also going to Los Angeles and maybe even taking in (观看) a Lakers basketball game. So I hope you enjoy that very much.

I want to extend my deepest welcome to you, and look forward to a future of improved dialogue and increased cooperation in the years to come.
