劍橋雅思9 Test1 Passage2閱讀答案解析
第14題答案:iv
對(duì)應(yīng)原文:B段:In discussing whether we are alone,most SETI scientists adopt two ground rules.
答案解析:B段開頭就提到,在討論我們是否獨(dú)自存在時(shí),大多數(shù)SETI科學(xué)家都采取兩項(xiàng)基本原則。iv選項(xiàng)中underlying與ground對(duì)應(yīng),assumptions與rules對(duì)應(yīng),search ofr extra-terrestrial intelligence是SETI的全稱,由此判斷答案為iv。
第15題答案:vii
對(duì)應(yīng)原文:C段:it seems inconceivable that at least one of these planets does not have a life form on it
答案解析:C段中部提到,所有這些行星上都不存在生命似乎難以想象。隨后又介紹了具體的數(shù)字文章來自 雅思和可能的概率。vii選項(xiàng)“其他行星存在生命的可能性”相當(dāng)于對(duì)此進(jìn)行了總結(jié),由此確定答案為vii。
第16題答案:i
對(duì)應(yīng)原文:D段:It turns out that,for a given amount of transmitted power,radio waves in the frequency range 1000 to 3000 MHz travel the greatest distance,and so all searches to date have concentrated on looking for radio waves in this frequency range.
答案解析:D部分開頭提到,1000-3000赫茲的電波能夠穿越最遠(yuǎn)的距離,而迄今為止的搜索也都集中在這個(gè)頻段。后面就開始講解具體的搜索操作。由此確定i選項(xiàng)為答案。
第17題答案:ii
對(duì)應(yīng)原文:E段:There is considerable debate over how we should react if we detect a signal from an alien civilization
答案解析:E段開頭就提到,對(duì)于我們收到來自外星信號(hào)時(shí)該如何回應(yīng)存在許多爭論。隨后就開始說明回應(yīng)時(shí)存在的具體問題。Appropirate responses即對(duì)此的概括,由此確定答案為ii。
第18題答案:several billion years
對(duì)應(yīng)原文:A段:Since the lifetime of a planet like ours is several billion years…
答案解析:從題干中可以推測,答案應(yīng)該是地球的年齡,而整篇文章中只有A段中部提到了這一內(nèi)容,由此確定答案為several billion years。
第19題答案:radio(waves/signals)
對(duì)應(yīng)原文:D段:It turns out that,for a given amount of transmitted power,radio waves…travel the greatest distance,and so all searches to date have concentrated on looking for radio waves in this frequency range.
答案解析:D段開頭提到,傳播信號(hào)的方式受到限制,頻率在1000-3000Mhz之間的電波可以傳遞最遠(yuǎn)的距離。而后面所說的搜尋內(nèi)容也證實(shí)了這一點(diǎn),由此確定答案為radio waves。
第20題答案:1000(stars)
對(duì)應(yīng)原文:D段:One part is a targeted search using the world’s largest radio telescopes…searching the nearest 1000 likely stars
答案解析:根據(jù)題干most powerful與largest的對(duì)應(yīng)定位到這句話,從題干中可以看出答案要填恒星的數(shù)量,由此鎖定1000。
第21題答案:YES
對(duì)應(yīng)原文:A段:It is even possible that the older civilization may pass on the benefits of their experience in dealing with threats to survival such as nuclear war and global pollution,and other threats that we haven’t yet discovered.
答案解析:A段最后提到,古老文明的經(jīng)驗(yàn)可能幫助我們處理諸如核戰(zhàn)爭和全球污染一類的威脅,以及其他我們尚未發(fā)現(xiàn)的威脅。題干只是將threats替換為problems,其他基本原詞出現(xiàn)。由此判斷答案為YES。
第22題答案:YES
對(duì)應(yīng)原文:B段:we are looking for a life form that is pretty well like us
答案解析:B段中部提到,我們正在尋找一種跟我們十分相似的生命形式。題干中find,resemble,humans分別與look for,like和us對(duì)應(yīng),in many ways與該句后面的解釋對(duì)應(yīng)。即題干中所有的信息在原文中都可以找到依據(jù),由此確定答案為YES。
第23題答案:NOT GIVEN
對(duì)應(yīng)原文:無
答案解析:原文中分別提到澳大利亞和美國的搜尋工作,至于兩者是否合作則完全沒有說,因此判斷為NOT GIVEN。
第24題答案:NO
對(duì)應(yīng)原文:D段:Until now there have not been any detections from the few hundred stars which have been searched.
答案解析:D段中部明確提到,到目前為止,在已經(jīng)搜尋的上百個(gè)恒星中沒有任何發(fā)現(xiàn)。題干中的敘述與此完全相反,由此確定答案為NO。
第25題答案:NOT GIVEN
對(duì)應(yīng)原文:D段:when the US Congress NASA 110 million per year for ten years to conduct a thorough search for extra terrestrial life.
答案解析:原文中只是提到國會(huì)給予NASA撥款,至于國會(huì)議員的態(tài)度則完全沒有說。我們無從推測是否有人不滿。由此判斷答案為NOT GIVEN。
第26題答案:NO
對(duì)應(yīng)原文:E段:Everybody agrees that we should not reply immediately.
答案解析:原文中明確提到,所有人都同意我們不應(yīng)該立刻回復(fù)。題干中的it will be important to respond promptly與此完全相反,由此判斷答案為NO。
