Taking a ten to 15 minutes' break every hour while working is a good way to help avoid this and rest your eyes, though your _5_ may not be as generous with your break periods. If possible, break up computer tasks and non-computer tasks throughout the day as much as possible.
One of the major improvements in computer screens has also helped Still, even an LCD screen, if it is not adjusted _6_ or if it is too bright, can be just as hard on the eyes.

解题思路

Passage 22
解题思路
1.[K] ... with computer screens and eye strain作后置定语，修饰名词questions,因此空格处应填入动词分词，且能与with搭配。词库中associated符合句意，指这些问题把电脑屏幕和眼睛疲劳“联系”起来。
2.[E]空格是介词with的宾语，为名词。此处指出视觉疲劳最先出现的症状，名词词库中soreness符合句意，表明视觉疲劳最先的症状是眼睛感到“酸痛”。
3.[M]空格后是名词，且与前面的dry eyes为并列关系，由此可见空格处最有可能是形容词，说明视觉疲劳对视力的影响，分词blurred符合句意,blurred vision意为“视觉模糊”。
4.[A]空格所在定语从句主语、系动词、表语都有，可见空格应该是副词，修饰unclear。此处选用somewhat最为合适，意为“电脑对视力的影响程度还不怎么清楚”。
5.[J]空格前的形容词性物主代词提示此处应填入名词，句末提到的“对休息时间没那么大方”可推知此处说的是
上司或老板，故选employer。
6.[F]空格所在句子的主句内容是“液晶屏也可能对眼睛造成伤害”，if从句用以说明液晶屏会伤害眼睛的条件，该从句主谓结构完整，由此可见应填人副词，properly代入文中意为“如果液晶屏调试不得当”，符合句意。
7. [I]空格在不定式标记to之后，应为动词原形，并可与介词for连用。此句说明为什么许多人喜欢把液晶屏的亮度调高,compensate符合句意,该句的意思是：人们喜欢把液晶屏调得很亮，以抵消因为看液晶屏的角度不正确而造成的“纱门效应”的影响。
8.[C]此处应为名词、形容词或分词,作situation的定语。句子开头的fortunately(庆幸的是）表明此处应该讲电脑对眼睛的影响并不是太糟糕，故选temporary “短暂的”。
9.[G] however表明此句与上句形成对比，上句讲的是得到足够的休息(rested long enough),由此可知，本句讲的是休息不充分。空格处应填入副词,词义与long enough接近,词库中sufficiently符合语义。
10.[O] once引导的条件从句里，缺少谓语，因此空格处应该是动词。该从句是对现在的假设，谓语动词应使用一般现在时。the symptoms may return肯定与继续使用电脑有关，resume符合此处语义。注意，不要受空格前的they appeared时态的误导，错误断定此处要使用过去时。
