2.Whether it's for a hobby or profession,photography has always been highly valued.Photography has been around for over a hundred years,but what has recently revolutionized it is digital photography.
A digital camera looks like a film camera,but it works differently.A digital camera takes pictures or a video by using a CCD sensor instead of film.The data about the images are electronically saved on a flash card.Later on,the flash card can be removed from the camera and put into a card reader.The card reader can be plugged into a computer's USB port.The images and videos can then be saved on a computer for viewing,editing,emailing,or printing.
Digital photography received a great deal of criticism in its beginning stages,but with its continued development,it is now capable of producing images of a quality that is similar to.or even better,than that of film photographs.However,what really makes digital photography attractive is its convenience and low cost.Instead of having to go to a lab and waiting to get pictures developed to see what they look like,you can always view the images or-video on the LCD screen that is on the back of the camera.Not only does this feature save time,but it also prevents common mistakes like using a wrong exposure(曝 光) that could ruin an image or video.
With the usage of computer programs like Photoshop,more serious photographers can edit their images without the expense of a darkroom.Digital photography is also friendlier to the environment,as harmful chemicals that are needed in the development of film are not used in digital photography.Printing only the best pictures and not having to buy film make digital photography much cheaper.

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了數(shù)碼攝影在攝影界的革命,它起先由于質(zhì)量原因不被看好,但隨著科技的發(fā)展,越來越受歡迎.
解答 25.C.細(xì)節(jié)理解題.根據(jù)第二段:A digital camera takes pictures or a video by using a CCD sensor instead of film可知數(shù)碼相機拍照或用CCD傳感器代替電影視頻;故選C.
26.A.推理判斷題.根據(jù)第三段:Digital photography received a great deal of criticism in its beginning stages,but with its continued development,it is now capable of producing images of a quality that is similar to.or even better可知公眾首先反對數(shù)碼攝影是因為這些照片不如電影攝影機那樣好;故選A.
27.D.細(xì)節(jié)理解題.根據(jù)最后一段:Digital photography is also friendlier to the environment,as harmful chemicals that are needed in the development of film are not used in digital photography.Printing only the best pictures and not having to buy film make digital photography much cheaper可知數(shù)碼攝影是環(huán)境友好型是因為顯影圖片不需要有害化學(xué)物質(zhì),圖片用電腦打印而不是膠片以及攝影師不必在暗房工作;故選D.
點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
