分析 本文是一篇科教類閱讀,屬于說明文,科學(xué)家們宣布,他們發(fā)現(xiàn)了這個引力波,證實了一個世紀前由愛因斯坦所做的預(yù)測.本文以此展開,主要講述了有關(guān)宇宙的一些發(fā)現(xiàn).
解答 29.D.細節(jié)理解題.根據(jù)The discovery,made with the Laser Interferometer Gravitational-Wave Observatory,known as LIGO,is the milestone(里程碑)in a decades-long search for signs of this phenomenon."The discovery will open a new window onto the universe,"said David Reitze,executive director of LIGO.可知,因為LIGO的發(fā)現(xiàn)為探索宇宙提供了多種方式.故選D.
