分析 這篇文章主要向我們介紹了一些關(guān)于宇宙中星球的天文知識.利用天文望遠(yuǎn)鏡我們可以觀察到太空中更多的物體,更為詳細(xì)地了解星星.還有一些我們看不到的星星,它們靠氣體燃燒發(fā)光,當(dāng)氣體燃盡,它們便成為被叫做黑洞的神秘死星.
解答 32.A 細(xì)節(jié)理解題.根據(jù)第四段的But when the gases run out,the star stops burning and begins to die.描述,可知當(dāng)氣體燃盡,星星便停止燃燒,我們就開始看不到它們.故選A.
33.D細(xì)節(jié)理解題.文章沒有提及白矮星與黑矮星的大小比較,故選D.
34.A推理判斷題.根據(jù)第二段的that's because they're invisible.They're the mysterious dead stars called black holes.可知當(dāng)星星成為被叫做黑洞的神秘死星后就看不見了,故選A.
35.B細(xì)節(jié)理解題.根據(jù)倒數(shù)第二段的A black hole is so tightly packed that its gravity sucks in everything-even light.The light from a black hole can never come back to your eyes.That's why you see nothing but blackness.可知,黑洞是如此緊密,它的引力吸收一切甚至是光.從黑洞發(fā)出的光永遠(yuǎn)不能回到你的眼睛.這就是為什么你看到的只是黑暗.故選B.
點(diǎn)評 本文是一個科技類閱讀理解,題目涉及多道細(xì)節(jié)理解題,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).
