问题 单项选择题

让摄影师自己控制所需要的最大或最小的景深限度的曝光模式是______

A.程序自动曝光
B.光圈优先曝光
C.快门优先曝光
D.多点自动曝光

答案

参考答案:B

解析:本题主要考查的知识点是相机自动曝光的三种模式。
在自动曝光三种模式中,程序自动曝光模式不需要摄影者对光圈和快门速度做出设定,因而在大部分情况下都被用在普通民用照相机上;光圈优先曝光模式的优点是可以让摄影师自己控制所需要的最大或最小的景深限度,是一种半自动的曝光模式;快门优先曝光模式也是一种半自动的曝光模式,优点是可以让摄影师自己选择是要凝固主体瞬间的动作还是要拍摄其运动轨迹。结合题干考查要求,本题选B。

                                            Dog Translation Products Coming to U. S.

     A Japanese toy maker declares that they have developed a gadget that translates dog barks into human

language and plans to begin selling the gadget--under the name of Bowlingual--in U. S. pet stores and gift

shops this summer.

      Tokyo-based Takara Co. Ltd. says about 300, 000 of the dog translator gadgets have been sold since it

was on sale in Japan late last year. It is forecasting far bigger sales once an English language translation for

dogs comes to America in August. The United States is home to about 67 million dogs, more than six times

the number in Japan.

      "We know that the Americans love their dogs so much, so we don't think they will mind spending $ 120

on this product," the Takara marketing manager said during an interview at a recent pet products conference

in Atlanta.

     Regarded as one of the coolest inventions of 2002 by Time magazine, Bowlingual is made up of a 3 - inch

long wireless microphone that is fastened (绑/系) to a dog collar and sends out sounds to a small console (控

制台) that is connected to a database (数据库). The console divides each bark into six emotional types-happiness, sadness, disappointment, anger, threat and desire--and shows common phrases, such as "You're ticking me

off," that fit the dog's emotional state.

     Takara says it has spent millions of dollars developing the gadget in cooperation (合作) with famous sound

experts and animal behaviorists.

     One thing that does appear certain is that the markets for animal translation products will likely remain a

dog's world since Takara has no plans to develop a similar gadget for cats. "They are too unpredictable (反复

无常)," the marketing manager said.
