我的貓咪作文400字

　　Thediscovery of subsurface life on Earth, surviving independently from surfacelife, refuted the belief that biological processes require not only liquidwater but sunlight as well, thus greatly enhancing the possibility of lifebeyond Earth. Take Jupiter’s moonEuropa. Space probes show a body covered with a thick layer of ice. AsEuropa orbits its planet, however, it flexes due to the gravitationaltug-of-war between it, its sister moons, and Jupiter. Through friction, thisflexing produces heat in the moon’s interior capable of melting ice. Indeed,observations suggest liquid water exists beneath Europa’s icy crust.Photosynthetic life is impossible there because sunlight is completely absent,but life such as the microbes that flourish deep within earth may still bepossible.

　　The highlighted sentence “take Jupiter’s moon Europa” serves tointroduce

　　A. aninstance that allows a hypothesis to be tested

　　B. speculationgrounded in empirical discovery

　　C. a deductionfrom a newly advanced hypothesis

　　D. alarge-scale effect of an apparently insignificant contingency

　　E. thederivation of a contradiction to refute a claim

　　解析

　　閱讀思考呀!注意段落結構和作者思路呀!

　　答案：B

　　解析：為什么是B不是A呢?為什么呢?為什么呢?

　　要看文章結構呀!文章首先說(shuō)地球上的一個(gè)重要發(fā)現，接著(zhù)說(shuō)該發(fā)現提高了天外星體存在生命的可能性。然后就是這句高亮句：take Jupiter’s moon Europa。這確實(shí)是一個(gè)例子，但后文對其描述用的是“may still bepossible”這樣的文字。所以B選項speculation ，結合前文的empirical discovery是對其更準確的概括。A選項to be tested 原文是沒(méi)有依據的。
