推理判斷題，答案A。據(jù)第二段最一“l(fā)ights,knownasadaptivesignals,havetosignificantdeclinesinboththetroubleandcostoftravelsbetweenworkand這燈，被稱為適應性信號燈，已經(jīng)大大減少了通勤的麻煩和花)最一段第一“InBellevue,theswitchtoadaptivesignalshasalessonthevalueofapproaches.(在Bellevue，適應性信號燈的轉變是一個在歡迎新方法的價值方面的榜樣”可推知，從Bellevue的功中可以得出，嘗試新事物是值得的。故選項?！济}探究所謂科技說明文是研究自科學與技術的文章明文是對事物或事理進行客觀說明的一文體，它以說明為主要表達方式，通過解說事物或闡明事理，達到教人以知識的目的，在結構往往采用總分遞進等方式按一定的順如時間空從現(xiàn)象到本質進行說明說文的特點是客觀練、語言準確、明了，文章很少表達作者的感情傾向。閱讀說明文的重點在于讀懂它說明的事物或理，了解事物的性質、構造、成因、功能等，了解事理的含意、特點等。最近三年年，說明文的出現(xiàn)變不大，一直很穩(wěn)定，選材通常是各學科的前沿問題；高科技領域的科研成果；人們比較關心的社會問題人文方面的經(jīng)典。由于閱讀理解題的設置采用漸進式，即由簡到難的方式，因此說明文是高考試卷中閱理解題中相對比較難的，通常后置。閱讀理解試題的中要考點之一是考查學生對詞匯和句式的掌握。說文的詞匯和句式的運用較別的體裁的文章難度更大。詞匯運用靈活，同一詞的不同詞性的用法交替出現(xiàn)未列入考綱的生詞較多通達到了不過考生可以通過說明文的語言特點來幫助理解語篇例如同位語、下定義、解釋、舉例、同義詞、反義詞、上下義詞以及標點符號（如破折號、冒號都有表示解和說明）等?！冀忸}秘籍說明文是對事物的形狀、性質、特征、成果或功用等進行介紹，解釋或闡述的文章。把握所說事物的特征和本質是理解說明文的關鍵。說明事物特征的方法很多，主要有定義法、解釋法、比較法、喻法、數(shù)字法、圖表法、引用法和舉例法等。數(shù)說文在閱讀數(shù)字說明文時要特別注意文中數(shù)字的含義，從這些數(shù)字中可以找到文章的主要內容。解說文解釋說明文著重說明事物的本質、特征和功用等。許多科普文章都屬于這一類。在閱讀這類文時要學會解決what,how,why等類的問題。們是文章的關鍵。如能帶著這些問題閱讀，將會更迅速抓住文章的主題。比說文比較說明文是通過對比方法說明問題。在閱讀這類文章時要善于把握全篇陳述的基本傾向。作在談論一

個有爭議的問題時總要顧及到爭議的各個方面般情況下的陳述總要傾向于某一種觀點。推判題做這類題要求考生在閱讀理解整體語篇的同時，又要求學生對作者的態(tài)度、意圖及文章細節(jié)的展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點。不要主觀臆斷，憑空想，任意發(fā)揮而走入誤。學生要學會運用主題句去推測摩文字背后作者的意圖用歸納對演技能，運用背景知識去挖掘文章深層含義，從而正確理解作者的言外之意，同時認真體會文章的語氣感情基調(如：否定、厭惡、反問、諷刺等這類試常如句發(fā)：①canyouconclude/implyfromthispassage?②’stheauthor（度）③infer/learnfromthepassagethat...總之，為提高閱讀理解能力，在閱讀時應抓中心思,作者意圖及關鍵詞語，運用聯(lián)想比較，歸納，推測等方法，得出最佳結論，選擇最佳答案，不能主觀臆測，把自己的觀點強加進去，與文章觀點混為一談。經(jīng)過長時間有計有目的的系統(tǒng)訓練，學生加快閱讀速度，提高閱讀的正確性，使兩者有機地統(tǒng)一起來以提高學生閱讀英語和運用英語進行交際的能力繼續(xù)學習和運用英語切實打好基閱讀是一種綜合性很強的語言實際活動。我們只有進行大量的課內外閱讀，掌握一定的閱讀技巧，正確用閱讀方法，才能有效地提高閱讀理解能力?！佳侯}沖關Passaage1(2020·河5月模擬，C)
