答案:EDACDCC
1(E)
首段提取astronomers就asteroid是否有satellite存在争议
“Until recently many astronomers believed that asteroids travel about the solar system unaccompanied by satellites”
“Theoreticians could have told them otherwise”
“Observations now suggest that asteroid satellites may exists not only in theory but also in reality”
接着以” Herculina”的例子作为asteroid有satellite的证据,但是“Even if every asteroid has as many satellites as can be fitted around it without an undue number of collisions, only one in every hundred primary occultations would be accompanied by a secondary event”有satellite的观测数据太少,所以反对者希望“photoelectric record were made of a well-behaved secondary event”。
因此,
“The Herculina event suggests that theoreticians’ views about asteroid-satellite systems may be correct, and astronomers agree about the kind of evidence needed to clearly resolve the issue”
2(D)
根据“Herculina has a satellite”定位原文
“The other, lasting about five seconds, preceded the predicted event by about two minutes. The presence of a secondary body near Herculina thus seemed strongly indicated.”
即“the occultation that occurred shortly before the predicted occultation by Herculina”
3(A)
根据“the attitude of astronomers toward asteroid satellites since the Herculina event”定位原文
“Yet even astronomers who find the case for asteroid satellites unconvincing at present say they would change their minds if a photoelectric record were made of a well-behaved secondary event”
只要证据合理,他们就会接受,即open-minded
“open-mindedness combined with a concern for rigorous standards of proof”
4(C)
根据“prior to reports of the Herculina event”就需要寻找“after the reports”后的变化
“With the Herculina event, apparent secondary occultations became “respectable”—and more commonly reported”
选项(C)
“If there were observations of phenomena exactly like the phenomena now labeled secondary occultations, astronomers were less likely than to have reported such observations”为同义表述
5(D)
根据“the frequency of reports of secondary occultations after the Herculina event”定位原文
“With the Herculina event……only one in every hundred primary occultations would be accompanied by a secondary event”
选项(D)为最佳复述
“Primary occultations by asteroids were reported to have been accompanied by secondary occultations in more than one out of every hundred cases”
本题只能确定为最佳选项,而不是正确选项,其实选项(D)与原文也有出入,只是与其它选项相比较而言它最为准确
6(C)
经过前面几题的思考及全文的阅读,“review the development of ideas among astronomers about whether or not satellites of asteroids exist: W'”最为恰当
7(C)
“most help to resolve the question of whether asteroids have satellites”,也就是说,如何解决asteroid/satellite在astronomers间的分歧,全文只有在最后一段提到,即
“Yet even astronomers who find the case for asteroid satellites unconvincing at present say they would change their minds if a photoelectric record were made of a well-behaved secondary event.”
选项(C)“a photoelectric record of a well-behaved secondary occultation”为原文提到的方法
