【解析】

试题分析: 本文就如何解决视觉疲劳提出几点建议:1.注意休息,不要用眼太多; 2. 减少眩光; 3. 调整对比度;

4. 锻炼你的眼睛。

【1】G考查对上下文语境的理解。空前一句的意思是：无论是从工作在一台电脑、 看电视、 开车或任意数量的其他活动，你的眼睛会很累，不能集中精力。空后一句的意思是：这里是四个简单的贴士，以帮助防止眼睛疲劳。 所以这里选G（严重的视神经疲劳会导致一系列其他的问题如近视。）与前文一致。

【2】D考查对上下文语境的理解。空前一句的意思是：你的眼睛使用不只一套的肌肉。这意味着你可以用另一套同时放松一套。空后的意思是：如果您在您的计算机，往窗外看了一会儿。如果你在开车，经常检查你的速度表。所以这里选D（改变你的焦点从近到远交替。）与上下文一致。

【3】F考查对上下文语境的理解。空前一句的意思是：尽可能使用非反射界面。空后一句的意思是：读的时候要尽量与界面保持90°角。所以这里选F（例如，读纸质的而不是从电脑屏幕上读。）与前文一致。

【4】E考查对上下文语境的理解。空前一句的意思是：确保良好的对比度；空后一句的意思是：保持周围的照明。所以这里选Ｅ（但是，与周边环境对比太大会导致紧张。）与上下文一致。

【5】A考查段落大意的归纳。本段的意思是：眼睛的污点实际上是控制眼睛的肌肉。加强一系列的眼保健操，会有效地防止眼睛疲劳。所以这里选Ａ（锻炼你的眼睛。）是本段的大意。
