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。

Few Americans remain in one position or one place for a lifetime. We move from town to city to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each move we are forever making new friends, who become part of our new life at that time.

For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friendship is possible.

The word “friend ” can be applied to a wide range of relationships ---- to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant.
