任務型讀寫(共10小題;每小題1分,滿分10分)

       閱讀下面短文,根據所讀內容在表格中的空白處填入恰當的單詞。

       注意:每空格只填一個單詞。

       As more students begin to use computers for longer periods of time, more of them are suffering from eyestrain (視疲勞).Just a few hours in front of a computer screen can make a person's eyes feel tired and painful.A number of eye doctors have studied this growing problem and have found ways to deal with it.Following their advice will help keep computer users more comfortable.Here is some of the advice.

       The light in a room shouldn't be brighter than the computer screen itself.In many classrooms, however, the lights are far brighter than they should be..Students can block some of this light by wearing baseball caps if they're allowed at school.

       A special computer screen should be used to cut down on bright light because it is especially tiring to the eyes.Another problem to avoid is the wrong kind of contrast.It is best to have dark letters on a light background.This causes less eyestrain than light letters on a dark background.

       Students should be seated so that they are looking down at the computer screen rather than straight ahead, which is a far more tiring angle.The top of the monitor should be slightly lower than the top of the head.

       The length of time students spend in front of a computer screen leads greatly to eyestrain.Students should take frequent breaks by looking away from the screen every fifteen or twenty minutes.During

that time they should either close there eyes or focus on an object at a distance. Long – term computer use can dry out the eyes, so students should remember to blink frequently while in front of the screen.
