21、的空间来产生能量，太阳能树仅需要大约4平方米的空间就能产生等量的能量。由此可推断出，太阳能树是节省空间的。故选B。18D推理判断题。根据第三段中的“they will collect more energy.exposed more to the sun”可知，太阳能树的独特设计使得太阳能电池板能更多地接触到太阳光，也就是说，太阳能树设计的灵活性使得它能收集更多的能量。故选D。19A写作目的题。纵观全文可知，本文主要介绍了一项新的科技发明太阳能树，所以A项最符合题意。故选A。.语篇解读本文是一篇记叙文。作者通过描述自己家三代人之间代代相传的节俭教育，说明学校的节俭教育固然重要，但父母更要树立好
