【解析】

試題分析：文中講解了幾個(gè)讓人們遠(yuǎn)離輻射的方法，可以喝綠茶，也可以做一個(gè)面膜，還可以換一臺(tái)新的電腦。

1. tea can be absorbed（吸收） by the body easily into a form of vitamin A, which helps reduce radiation．可知前文可能有提到綠茶，故選E。

2.

3. brighter the screen the higher the radiation there will be and vice versa，可知前文應(yīng)有對(duì)亮度的描述，故選A。

4. sure you do a skincare protection before sitting in front of the computer，可知確在坐在電腦之前要有一定的皮膚保護(hù)，B選項(xiàng)使用一個(gè)面膜保護(hù)你自己。所以B符合題意。

5. computer in general, has one to two times more radiation released than the new one within the same distance．可知后文提到了舊電腦的輻射較大，可知前文的應(yīng)是關(guān)于新電腦的句子，所以該題選F。

考點(diǎn)：考查對(duì)科普知識(shí)類短文閱讀。
