问题 单项选择题

表浅且腔壁光滑的巨大空洞()

A.浊音或实音

B.鼓音

C.浊鼓音

D.过清音

E.空瓮音

答案

参考答案:E

解析:

正常的肺脏,除掩盖心、肝部分外,叩诊时均为清音,否则均为异常叩诊音,提示肺及胸膜、膈或胸壁的病理改变。若肺内有表浅且腔壁光滑的巨大空洞或张力性气胸患者,叩诊时局部虽呈鼓音,但因具有金属性回响,故又称空瓮音;胸部异常浊音或实音是由于肺组织含气量减少或不含气的肺病变(肺炎实变期、肺不张、肺结核、肺梗死、肺脓肿、肺癌、肺水肿等)、胸膜病变(胸腔积液、胸膜肿瘤、胸膜肥厚)、胸壁病变(胸壁水肿、胸壁肿瘤等)引起;鼓音见于肺内含气量明显增多如肺大疱和大空洞等,或胸腔内积气如气胸等;浊鼓音发生于肺泡壁松弛、肺泡含气量减少的情况下,如肺炎充血期或消散期、肺不张、肺水肿等,局部叩诊时可呈现一种兼有浊音和鼓音特点的混合性叩诊音,称为浊鼓音;过清音见于肺弹性减弱而含气量增多时,如肺气肿等。

Directions: For each blank in the following passage there are four words or phrases marked A,B, C and D.

     The first attempt of even the most talented artists, musicians, and writers is seldom a masterpiece, If you
consider your drafts as dress rehearsals (彩排), or tryouts, revising will seem a natural part of the writing   1  
     What is the purpose of the dress rehearsals and the out-of-town previews that many Broadway shows go
through? The answer is adding, deleting, replacing, reordering,   2   revising. Andrew Lloyd Webber's musical
Phantom of the Opera underwent such a process.
     When Lloyd Webber began writing in 1984, he had in mind a funny, exciting production. However, when
Phantom opened in London in 1986, the audience saw a moving psychological love story set to music. The
musical had.   3   several revisions due, in part, to problems with costuming and makeup (戏服和化妆). For
instance, Lloyd Webber   4   some of the music because the Phantom's makeup prevented the actor from
singing certain sounds.
     When you revise, you change aspects of your work in   5   to your evolving purpose, or to include   6   
ideas or newly discovered information.
     Revision is not just an afterthought that gets only as much time as you have at the end of an assignment. 
  7  , it is a major stage of the writing process, and writers revise every step of the way. Even your decision
to   8  . topics while prewriting is a type of revising. However. don't make the mistake of skipping the revision
stage that follows   9  . Always make time to become your own  10  and view your dress rehearsal, so to speak.
Reviewing your work in this way can give you  11  new ideas.
     Revising involves  12  the effectiveness and appropriateness of all aspects of your writing, making your
purpose more clearly, and refocusing or developing the facts and ideas you present. When you revise, ask
yourself the following questions, keeping in mind the audience for whom you are writing: Is my main idea or
purpose  13  throughout my draft? Do I ever lose sight of my purpose? Have I given my readers all of the  14 
 that is, facts, opinions, inferences-that they need in order to understand my main idea? Finally, have I included
too many  15  details that may confuse readers?
