Do you know how to write an English letter and envelope?

When we write a letter in Chinese, we always put the date at the end of the letter. But it is different in English. We have to put it on the top of the right corner. And above the date, we also write the number of our house and the names of our street, city and country. To begin the letter, we always use the word like "Dear sir",  "Dear Mr./Miss./Ms.…". To end the letter, we usually use words like "Yours”, “Yours ever" or "Truly yours".

Now read the following envelope, please.

解答题

某校科技活动小组利用学校空地建立了一个小型农业生态园,在园内,同学们开展了一系列植物栽培、种植和探究活动.请分析回答下列问题:

(1)在向生态园内移栽花卉时,同学们采取了三项措施:①选择在傍晚或阴雨天进行移栽;②去掉移栽花卉的部分叶片;③让移栽花卉的根部尽量带着一个“土坨”.其中①②措施都是为了______;③是为了______.

(2)某组的同学把菜豆种子播种在苗床上,在适宜的条件下种子萌发,观察发现,第6天幼苗出土后,子叶展开;第9天幼叶出现.研究小组的同学从种子到幼苗形成期间,每天测定其干重,并绘成右图所示的曲线.注:横轴表示时间(天);纵轴表示干重(毫克/株)).请你分析回答:

①前6天干重逐渐减少,原因是菜豆种子在萌发过程中,通过______消耗了种子中的有机物.

②从第6天开始,干重开始逐渐增加,原因是展开后的幼叶能够______.

(3)为探究无机盐对植物的影响,同学们在园内选取了发育情况相同的两株健壮天竺葵幼苗,分别放在等质量的甲、乙两瓶液体中培养(甲中装蒸馏水、乙中装土壤浸出液).一段时间后,甲、乙两瓶中的植株变化如下表:

植株实验前质量/克实验后质量/克生长情况
92116矮小、纤细、叶色变黄
91258茎粗、枝多、叶色浓绿
①比较甲、乙两瓶植株的变化,可以得出的结论是______.

②小明在上述探究的基础上,回家用土壤浸出液栽培了一株天竺葵,但一段时间后,他发现栽培的天竺葵生长情况并不理想,甚至还出现了烂根,试分析其可能的原因______.
