Answer 1

【答案】

【1】E

【2】G

【3】A

【4】B

【5】F

【解析】

【1】E 根据下一句Green tea can be absorbed by the body easily into a form of vitamin A, which helps reduce radiation. _绿茶很容易就被人体吸收，并形成维他命A，维他命A可以帮助减少辐射。可知本段介绍的抵抗辐射的方法是喝绿茶。故E项正确。

【2】G 在前句Green tea can be absorbed by the body easily into a form of vitamin A, which helps reduce radiation. 叙述了绿茶的一大作用就是被人体吸收形成维他命A，维A可以抗辐射，也可以提高我们的视力。所以G项叙述的是喝绿茶的另外一个好处。

【3】A 根据下一句The brighter the screen the higher the radiation there will be and vice versa.可知电脑屏幕越亮，辐射越厉害，也就是说要调整电脑屏幕的亮度。故A正确。

【4】B 根据前一句Make sure you do a skincare protection before sitting in front of the computer.可知本段讲述的是保护脸部，那么B项Apply a layer of facial mask to protect yourself.敷一层面膜保护自己符合段落大意。

【5】 F 根据本段Old computer in general, has one to two times more radiations released than the new one within the same distance.可知旧电脑的辐射是新电脑的两倍，那么为了减少辐射，最好是换用新电脑。故F项正确。
