Question

阅读下面的短文，根据所给语境，按要求完成下列各题。
①After Pluto (冥王星) was found in 1930, people took it as the ninth planet in our solar system(太阳系). But it isn’t like other planets. It is smaller and has an strange orbit(轨道). On August 24,2006， scientists said,“Pluto is not a planet.”
About 2,500 scientists met in Prague（布拉格，捷克首都）. At first, some of them said that there would be 12 planets in our solar system. In the end, the scientists said that only Mercury（水）, Venus（金）, Earth, Mars（火）, Jupiter（木）, Saturn（土）, Uranus（天王）and Neptune（海王）are the planets in the solar system. ②Each of these planets has its own orbit, and of the planets is big enough to be a planet. Pluto’s orbit overlaps (重叠) Neptune’s and it is smaller than the other planets. ③So Pluto is classified(划归/分类) as a dwarf planet (矮行星), but no longer a planet in the solar system.

Answer 1

小题1:found, eight
小题2:orbit, big(large)
小题3:所以（因此/因而）冥王星被划归到（划分为）矮行星，而不再是太阳系的（一颗）行星。

试题分析：本文介绍了冥王星在1930年被人们认为是太阳系的第九大行星。但是，在2006年8月24日，科学家又说冥王星不是一颗行星。因为每一颗行星都有自己的轨道，而且自己足够大能成为一颗行星。所以冥王星被划归到矮行星，而不再是太阳系的一颗行星。
小题1:根据After Pluto (冥王星) was found in 1930, people took it as the ninth planet in our solar system(太阳系)可知在1930年，冥王星被发现之后，人认为它是太阳系中第九大行星，也就是说在人们发现冥王星之前，人们认为太阳系里有八颗行星。故第一空为found, 第二空为eight。
小题2:根据②Each of these planets has its own orbit, and of the planets is big enough to be a planet. 可知每一颗行星都有自己的轨道，而且自己足够大能成为一颗行星。故第一空为orbit, 第二空为big或large。
小题3:根据is classified(划归/分类) as a dwarf planet (矮行星)的意思是被划归为矮行星。no longer的意思是不再是。in the solar system.的意思是在太阳系。故这句话的意思是：所以（因此/因而）冥王星被划归到（划分为）矮行星，而不再是太阳系的（一颗）行星。
