如图所示血管中(箭头表示血流方向),较粗的一端是(  )

A.静脉

B.动脉

C.毛细血管

D.动脉或静脉都有可能

答案

人体内的血管有动脉血管、静脉血管、毛细血管三种类型.动脉的功能是把心脏的血液输送到全身各处,故动脉内的血液流动方向是从主干流向分支,静脉的功能是把全身各处的血液送回心脏,故静脉内的血液流动方向是从分支流向主干,毛细血管管腔小,红细胞只能成单行通过.

  如图所示的血管中较粗的一端箭头表示其内的血液是从主干流向分支,因此是动脉.

Advertising Everywhere

      1     Now that messages can go around the world at high speed,the world isbecoming smaller and products can be sold everywhere.But it is true that the problems ofinternational advertising—problems of language and culture—have become larger than ever.For example,Braniff Airlines wanted to advertise its fine seals,but when its advertisement wastranslated from English into Spanish,it told people that they could fly without wearing clothes!

To avoid problems in translation,most advertisement firms are now writing completely new ads.In writing new ads,international advertisers must choose different methods of advertising for different countries.In some countries,an advertisement usually gives a description of the product

and explains why it is better than others.      2     But in Japan,the message is based more on situations and feelings than on words.For this reason,many television advertisements broadcast in Japan show people at a party,picnic,or in some other pleasant situations.They will

not say that a product is better than others.Instead,the goal will be to create a good feeling about

the product

        3     For instance,certain countries will not allow TV advertisements on Sundays,and others will not allow them for children’s products on any day.The world advertiser who does

not understand such laws aud customs will soon have problems.

Finally,there is the choice of what to advertise.      4    So the best advertisement in the world means nothing if the product is not suitable for the market.Comparing such as McDonald’s in Hawaii,you will find Chinese food provided on the menu.If you stop at a McDonald’s in Germany,you can order a beer with your meal.

All of these products must be sold with the right kind of message      5     But no matter how difficult this job may be,it is very important for global advenrtisers to do it well.Knowing how to advertise in the world market can help companies for success.

A.People around the world have different likes and dislikes.

B.This is true in the United States,Britain,and Gemany

C.They just show how the product is made

D.In the advertising industry,selling products is the most important goalE.International advertisers must also consider differences in laws and customs

F.It can be explained by a word,a passage,or even a picture

G.It can never be an easy job for advertisers to create message
