32.D。本题问及为什么要把种子放在嫦娥五号探测器里面。根据题干中的关键信息“the seeds placed inside Chang'e5”可将解题线索定位到第一段。然而，分析第一段后可知，该段只是介绍了种子被放置在嫦娥五号内部并围绕月球运行了大约15天，并未给出把种子放进探测器中的具体原因，故我们需要从接下来的段落着手分析。根据第二段第一句“Scientists wished tocheck what would happen to the seeds after being exposed to extraterrestrial(地外的)forces in lunar orbit'”可知，科学家们希望检查这些种子在月球道上暴露在地外力量下会发生什么，这揭示了为什么要把种子放在嫦娥五号探测器里面。D项“让它们处于一个特殊的环境”与此相符。故选D。33.B。第四段第一句中的“Space breeding can generate mutations faster and more conveniently than ground-based experiments'”讲到，与地面实验相比，太空育种可以更快地产生突变，但这并不意味着空间诱变育种的过程不耗时。A项曲解文意。第三段倒数第二句“Researchers observe and examine several generations of plants grown from space-bred seeds and investigatetheir mutations一some are positive and desirable while others are negative.”讲到，有些突变是有益的、可取的，而另一些则是有害的。由此可知，突变是随机的。故选B。第三段倒数第二句只是讲到，有有益的突变，也有有害的突变，但并未指出哪种形式的突变更多一些。C项曲解文意。第三段最后一句“Those with positive mutations will be kept and analyzed,and willbe introduced to farmers after their certification and approval..”讲到，只有有益突变的植物将被保留并进行分析，在获得认证和批准后，供农民尝试种植。D项扩大了范围。34.D。本题问及作者的态度是什么。基于第四段第一句“Space breeding can generate mutations faster and more convenientlythan ground-based experiments and can bring about some desirable traits'”中的“faster,more conveniently,.desirable”和最后段最后一句“marking a historic accomplishment44 years after the last lunar substances were taken back.”中的“historic”得出
