下列诊断矽肺的主要依据正确的是( )

A.临床症状、体征、职业史
B.胸透、职业史
C.胸片、职业史
D.化验检查、X线胸片
E.接触粉尘浓度、X线胸透

答案

参考答案:C

解析:矽肺是在生产过程中长期吸入含游离二氧化硅的粉尘引起的以肺组织进行性、弥散性纤维增生为主的全身性疾病。其基本病理改变是肺组织弥漫性纤维化和矽结节形成。因此矽肺诊断的依据是以职业史为前提,以胸片为主要依据,并结合临床表现,生产场所粉尘浓度测定,由矽肺诊断小组综合分析后集体诊断。

     A long weekend is a great opportunity to do something a little different. Many people use a long weekend for

a getaway, a short trip to leave the stress of their everyday lives behind and explore, learn, or relax.

     Hotel Romance

     Many hotels and resorts feature something special to start the getaway, such as champagnes, flowers, or

a fruit basket in the room on arrival. Getaway packages usually include a room with something special, a heart

shaped bed, for example. Additional benefits could be room service meals or other private dining, plus tickets

or discounts for local attractions.

     Visit a Spa

     Spa getaway can take place at a location that focuses only on spa services or at a hotel that offers a spa as

one of its features. Some spas emphasize treatments fit for their geographic area or a local attraction. A spa in

a grape growing region might provide grape juice masks, or a hotel near a hot spring could offer mineral baths.

Most spas offer a range of massage, health and beauty treatments, so a spa getaway can be relaxing with other

benefits.

     Learn a Skill

     A long weekend may not be enough time to become an expert at something new, but it provides a way for

people to begin their explorations. Some organizations offer intensive courses that last two or three days. People

with special interests can get away from their routines while learning such things as how to make beer, speak

a new language, or take better photos.

     Help Others

     Some organizations cooperate with businesses to have accommodations (住宿) and activities for short-term

volunteers. Most volunteer vacations involve ecology friendly or charity activities. A volunteer getaway is a way

to relieve stress and help others at the same time.

     Stay in a National Park

     For those who want to relax in a rural environment, a national park fits the bill. Most national parks provide

camping areas for tents and trailers. Several have cabins (小屋) within the parks available to rent. A getaway to

a national park provides privacy, stress relief, and the time to get to know some important natural resources.

单项选择题

美国前总统卡特访问日本的时候,从东京乘坐新干线到京都,一路下来,居然没发现农村。卡特很奇怪,同行的日本人告诉他,日本的城市与农村,从外观上看是没有区别的,从建筑的样式到公共设施的配备,从生活习惯到人的精神状态,都大致相仿。
我在一位日本农民家做过客,这家有六口人,住三套房,每套面积一百九十平方米。家中有三辆汽车,还有一个农具仓库,里面放满各式各样的农具,家中的生活设施也应有尽有。让我惊叹不已的是,男主人是个兰花专家,养了许多名贵的兰花,但他从来没有卖过一盆,养兰花仅仅是为了消遣。
由于农村的空气质量好,也不像城市那样拥挤,日本不少上班族在城市上班却住在农村。在东京、大阪这样的超级城市,这种情形更为普遍。于是,在农村出现了一个个与城市一般无二的生活小区。久而久之,生活习惯也同化了,再难分出城市或农村了。
真正反映“城乡差别”的是人均收入这一指标。据有关记载,日本自从1973年农村居民人均收入超过城市居民以来,这一状况一直持续至今,没有改变。日本百分之五的富豪人口中,农民占据主要的份额,年收入千万日元的农民极为常见。二十世纪90年代后,城市受泡沫经济的影响比农村更大,因此,“倒城乡差别”反被拉大了。

美国的前总统在日本发现了:

A.东京的新干线

B.日本没有农村

C.农村建筑漂亮

D.城市比如农村
