Answer 1

【答案】

【1】E

【2】G

【3】A

【4】B

【5】F

【解析】

試題分析：本文介紹了幾種減少電腦輻射的方法

【1】E本段是關(guān)于用綠茶來減少電腦輻射的影響，故E項(xiàng)正確。

【2】G綠茶還有另外的功能就是提高視力，故G項(xiàng)正確

【3】A根據(jù)下句The brighter the screen the higher the radiation there will be and vice versa.說明屏幕的亮度也是影響人們視力的原因，那么就要調(diào)整屏幕的亮度。故A項(xiàng)正確。

【4】B根據(jù)下一句Wash your face soon after using the computer在用完電腦以后要洗臉。那么之前也要采取措施，選項(xiàng)中只有B項(xiàng)是與之有關(guān)的。故B下符合上下文。

【5】F根據(jù)下句Old computer in general, has one to two times more radiation released than the new one within the same distance.說明舊電腦的輻射較大，那么應(yīng)該使用新的電腦。故F項(xiàng)正確。

【七選五題型分析】

分析篇章結(jié)構(gòu)，把握全篇文脈是閱讀填空題解題的關(guān)鍵，英語的語篇（discourse）通常是由句子和語段（sentence group）構(gòu)成的，語段是句子和語篇之間的中間層次，句子雖然能夠單獨(dú)地表達(dá)相對完整的思想，但是它不能表達(dá)多方面的、比較復(fù)雜的思想，只有把幾個(gè)句子結(jié)合為較大的言語片段，才能表達(dá)一個(gè)相對獨(dú)立的層意，所謂的“積句而成章，積章而成篇�！本褪沁@個(gè)道理。

分析文章的層次包含兩種形式：一種是分析整篇文章的層次，也就是段落，另一種是分析每一個(gè)段落內(nèi)部的層次，也就是語篇層次。

語篇與段落是有區(qū)別的，語段是篇章結(jié)構(gòu)的中間層次，是由句子到篇的一種過渡形式，段落（paragraph）是在某些語體（如記敘文、議論文）中比語段更大的意義單位，較小的段落可以只包括一個(gè)語段或一個(gè)句子，一般來說，一個(gè)段落通常由幾個(gè)語段構(gòu)成。構(gòu)成語段的方式有兩種，一是靠句際間意義的結(jié)合，如小題4 B根據(jù)下一句Wash your face soon after using the computer在用完電腦以后要洗臉。那么之前也要采取措施，選項(xiàng)中只有B項(xiàng)是與之有關(guān)的。故B下符合上下文。

二是靠句際間的關(guān)聯(lián)詞，邏輯性插入語來連接，在分析語段層次時(shí)，可以借助句際間的連接詞語作出判斷，但最主要的還是要真正體會句際間的意義關(guān)系，把握作者的思路，從語序上去發(fā)現(xiàn)斷續(xù)點(diǎn)，理清層次，好文章的層次非常清晰，只有層層入手，才能真正理解文章。如小題3 A根據(jù)下句The brighter the screen the higher the radiation there will be and vice versa.說明屏幕的亮度也是影響人們視力的原因，那么就要調(diào)整屏幕的亮度。故A項(xiàng)正確。
