1.D考查副词及语境的理解。句意:例如你从自行车上摔下来,摔断了胳膊,这样的伤害发生的非常快。much quickly 这个短语形式不对,much不能修饰副词原级;faster 更快的;slowly 慢的;quickly快的。根据下句话But computer injuries happen slowly可知,计算机对人体的伤害是很慢的,故这里作者举的例子是告诉我们,从自行车上摔下来这种伤害发生的很快。故选D。
2.B考查副词及语境的理解。句意:太多的光会伤害你的眼睛。Too many 太多,修饰可数名词;Too much 太多,修饰不可数名词;Much too 太,修饰形容词或副词;Many more更多。空后面的light是一个不可数名词,根据句意可知选B。
3.A考查连词及语境的理解。句意:太多的光会伤害你的眼睛,因此不要坐得离电脑屏幕太近。so 因此,所以;because 因为;but 但是;when当……时候。根据句意可知选A。

5.D考查副词及语境的理解。句意:有时候要记得让眼睛离开屏幕一下。这样可以让眼睛休息一下。Sometime 某时;Some time 一段时间;Some times 一些次;Sometimes有时候。根据文意可知,要让眼睛适当的休息一下,所以有时需要让眼睛离开屏幕,故选D。
6.D考查情态动词及语境的理解。句意:当你使用电脑的时候,窗户应该在你的左边或右边。can 能,会;may 可以,可能;must 必须;should应该。根据文意可知,这篇短文是作者对安全使用电脑,给我们提出的一些建议,故应该选D。
7.A考查不定代词及语境的理解。句意:如果窗户在你的前面,太阳和屏幕都会照射你的眼睛。both两者都; never 从不;all 所有的;neither两者都不。根据文意可知,如果窗户在你的前面,那么太阳光和屏幕都会照射你的眼睛,这里说的是两者都,故选A。
8.A考查动词词义辨析及语境的理解。句意:如果你长时间使用键盘,遵循以下的这些规则……。follow 遵循;work 工作;copy 抄写,复制;write写。根据文意可知,follow the rules是遵循规则的意思,故选A。
