我家窗外,不见绿荫,是高楼包围中遗留的一片灰扑扑的低矮的瓦房,使我得以望见一片天空,望见它的晴朗阴沉,星月风雨。当然,也得时常紧闭窗户,看那几根烟囱中逃窜出来的煤烟如何张扬肆虐。 

奇怪的是,燕子就在这样的环境中飞翔而至,像老朋友似的呢喃问候。 

一个暴雨来临前的黄昏,空中沉闷难耐。窗外的煤烟终于消失了,我可以打开窗户了,可以享受一番自然风的抚摸了。就在打开窗户的时候,我的眼睛明亮起来——两只燕子,正在窗外阴沉的天空下盘旋飞翔。那白色的肚皮,似闪电,昭示着一种高洁:那划破阴沉的长长的翅膀,透剔着搏击的力量;那如剪刀般张开的羽尾呵,剪裁出飞翔的希望。 

久违了,我亲爱的朋友!我亲爱的燕子!那些飞入平常百姓家的燕子,那些少时见过的在空中的电线上编织音符的燕子,那些春天在草丛中绿树林呢喃的燕子,早已成了过眼烟云,真真切切远离我们了。今天,这欢乐的,时而俯冲,时而奋飞,倏忽不见影踪,突然又出现在眼前的呼唤暴雨来临的燕子,让我边城中村夫,忧郁尽褪,灵魂随之飞翔。 

我打开所有的窗户,希望燕子疲惫的时候,飞进来歇一歇。但燕子终无此意,有时飞至窗前,又昂然而去,它们有自己的天空,在天空中,塑造着飞翔的灵魂。在那暴雨如注的夜晚,我梦见了好多飞翔的燕子。以后,在这个尽管没有“绿水人家绕”,而是乌烟熏人的境地,无论是刮风下雨,还是日山日落,不知为什么,我家窗外,总有两只燕子在飞翔——直到写这篇短文的时候。我想,也许是我们的生活中昆虫太多的缘故吧,燕子终究要出现的。不知什么时候,在这个 * * 攘往的世界,我喜欢独处。心灵在寂静中用眼睛去感悟春夏秋冬:在这个闷热潮湿的夏季,无疑让灵魂撒满了春天般的阳光。

A.本文的环境气氛是昏暗阴沉的,自始至终给人一种压抑沉闷之感。

B.本文有明暗两条线索,明线是写自然界的燕子,捕捉小虫的燕子;暗线写奋进执著的斗士,勇斗邪恶,装点春天的精灵。

C.本文的燕子是象征积极向上奋斗不息的力量,它成为作者视野中优美亮丽的风景。

D.本文寓情于景,景中显情,语言优美,很多语句化实为虚,也富有诗的韵味。

根据短文内容,从下框的A~F选项中选出能概括每一段主题的最佳选项.项中有一项为多余项.

A. Be well-organised.

B. Close with a Q & A.

C. Don't be contradictory.

D. Bring it to a specific end

E. Speak slowly and pause.

F. Drop unnecessary words

     Speaking to a group can be difficult, but listening to a bad speech is truly a tiresome task-especially

when the speaker is confusing. Don't want to confuse your audience? Follow these suggestions:

1.       

     When it comes to understanding new information, the human brain needs a little time. First, we hear the words; then, we compare the new information to what we already know. If the two are different, we need to pause and think. But abreathless speaker never stops to let us think about what he or she is saying and

risks confusing us. Slow it

2.      

     Sometimes we all start a sentence one way and then switch directions, which is very difficult to follow. When you the audience confuse your listeners with opposing information, you leave the audience

wondering what part of the information is right and what part they should remember. Instead of relying and keeping correcting yourself, work to get the facts clear and straight.

3.        

     Jumpng from point to point as it comes to your mind puts the onus (责任)on your listeners to make up

for your lack of organisation. And it's confusing for them to listen, reorganise, and figure out what you're

saying all at once. But going smoothly from one point to the next helps them understand information more

easily. You can arrange things from beginning to end, small to large, top to bottom or by some other order. Just be sure to organise.

4.     

     Repeated use of um, ah, like, you know and some other useless noises can drive an audience crazy. It makes the speaker sound uncertain and unprepared, and it can leave listeners so annoyed that they can't

pay attention. Recently I attended a speech that was marked by so many ums that audience members were rolling their eyes. Was anybody grasping the intended message? Um, probably not.

5.      

     Many speakers finish up their speeches with question-and-answer (Q & A) sessions, but some let the Q & A go on without a clear end. The audience is often left confused about whether the meeting is over

and when they can get up and leave. Do your listeners a favour by setting a time limit on questions, and

close your speech with a specific signal-even if it's something simple like, "If you have any more questions, you know where to reach me."

       Or even more to the point, conclude your speech with "Thanks for your time. "
