D.Morethan4,000planetsoutsidetheSolarSystemstillcannotsustainlifenow.
1.C.细节理解题。
根据第三段中的“…itslocationcouldmeanthatitisjustenteringanuncontrollablegreenhouseperiodofitsclimatehistory.”可知，“它的位置可能意味着它正在进入它的气候历史中不可控制的温室阶段”的说法只是一种推想，而不是已经进入了。
句中的“could”是关键词，它表明了一种假想的情况。
故答案为C项。
2.D.细节理解题。
根据第三段第一句话和第五段第一句话可知，答案应为D项。
3.A.推理判断题。
根据第二段第一句话“Kepler452b,whichhasbeennamedEarth2,issixbillionyearsold.”和第三段第一句话中的“Sincetheplanetis1.5billionyearsolderthanEarth,…”可以推知答案应为A项。
即地球存在的时间是：
（6billion–1.5billion=4.5billion）年。
其余各项虽然表述是正确答，但都是原文直接提到的内容，不是推断出来的。
