【参考答案】1．【答案】D【解析】推理判断题。通读全文可知，第一段介绍了植物的广泛分布、悠久历史和种类繁多，起到引导读者进入植物这个主题的作用。因此，正确答案是D。2．【答案】A【解析】细节理解题。根据“Plantsusephotosynthesistomaketheirownfood,andthatmeanstheyusesunlighttohelpthemproducefood(sugar)andoxygen.”可知，植物用阳光来帮助它们产生食物（糖分）和氧气，也就是进行光合作用。因此，正确答案是A。3．【答案】C【解析】细节理解题。根据“sotheyneedplants(orotheranimalswhicheatplants)togetthesugartolive.Theyalsoneedoxygentobreathe”可知，动物需要植物来获取糖分，还需要氣气来呼吸。因此，正确答案是C。4．【答案】B【解析】段落大意题。第一句是本段的主旨句，根据“Plantssharekeycharacteristics.”可知本段介绍植物的相似之处。因此，正确答案是B。5．【答案】D【解析】推理判断题。根据“Light,temperatureandwatercaninfluenceplantgrowth.It’simportanttoknowhowtheyinfluenceplantgrowth.”可知，最后一段指出光照、温度和水分对植物生长有影响，所以之后作者会谈论环境因素对植物的影响。因此，正确答案是D。6．【答案】B【解析】细节理解题。根据“Longago,whentheCreatorfirstplantedatreeinthegarden”可知，作者讲述了上帝种树的故事，所以作者是通过展示一个故事来开始这篇文章的。因此，正确答案是B。7．【答案】A【解析】细节理解题，根据“Inthedryseason,thesetreesarestandingtherewithoutleaves,andlookliketrunksstickingupintheair.”可知，旱季猴面包树的样子是没有叶子，像树干直立在空中。因此，正确答案是A。8．【答案】C【解析】词义猜测题。根据“Whenabaobabgetsold,itstrunkbecomeshollow.Anoldtreecanholdmanypeople.”可知，老树能容纳很多人，说明树干里面是空的：可推测出，empty意为“空的”，与hollow意思相近。因此，正确答案是C。9．【答案】D【解析】
