At a very young age,Oindrila Basu had no idea of 　1　 to live with nature.She would climb trees or destroy the nests of birds just for fun,like other kids.Once her mother caught her and got angry,and then the girl realized she 　2　(do) something terribly wrong. 
This is just a way that Basu’s parents shaped her understanding and appreciation of nature.　3　(live) in the countryside,she spent her youth studying ants before the rain,watching sunbirds drink honey,counting fireflies and watching young plants grow.Then her parents decided to move to a nearby city 　4　 better educational chances,and then she stopped having first-hand experience with nature. 
Later,as she struggled 　5　(choose) a college major,her mother suggested a career in forestry(林业).That’s when her journey began,and she fell in love with forestry.Away from the crowded cities,in the lap of the Himalayas,she graduated in forestry from Kumaun University,India.When she went on to study a 　6　(master) degree in forestry from the Forest Research Institute,India,she finally got introduced to a group of like-minded people,devoted to the International Forestry Students’ Association(IFSA). 
IFSA is a 　7　(globe) organization connecting students to exchange knowledge and participate in forestry activities.The youth joining IFSA 　8　(encourage) to undertake its task—to enrich forest education and spread a love of nature through events and exchanges. 
After six months of exciting international conferences and workshops,Basu,then 25,found her home—a family that loved forests as much 　9　 she did.She felt more active,so her passion had a direction.Now she wants to do more. 
As a key member of IFSA,Basu recalled the experience of joining it,“　10　(deliberate) or by accident,we chose forestry,or rather,forestry chose us.” 
（A）
1.how　考查副词。根据下句可知,为了好玩,她会爬树或者破坏鸟巢;又结合语境可知, Oindrila Basu在很小的时候不知道如何和大自然相处,故用how。
2.had done　考查动词的时态。句意:她的妈妈曾经抓住了她并且发怒了,然后这位女孩才意识到她做了非常错误的事情。根据该句中的“realized”,并结合句意可知,她做那些非常错误的事情发生在她意识到之前,表示过去的过去,故用过去完成时。
3.Living　考查非谓语动词。分析该句结构可知,动词live和主语she为逻辑上的主谓关系,故用其动词-ing形式。
4.for/with　考查介词。根据语境可知,此处表示“她的父母为了更好的教育机会决定搬到附近的一个城市”,表目的;此处也可以表示“她的父母决定搬到附近的一个有更好教育机会的城市”,表示“带有”,故填for/with。
5.to choose　考查非谓语动词。struggle to do sth为固定搭配,意为“努力做某事”,故该处用动词不定式。
6.master’s　考查固定用法。 master’s degree为固定用法,意为“硕士学位”。句意:当她继续在印度森林研究所攻读林业硕士学位时,她最终结识了一群志趣相投的人,他们都服务于国际林业学生协会。
7.global　考查形容词。形容词修饰名词,空处修饰名词organization,故用形容词。
8.are encouraged　考查被动语态。分析句子结构可知,该句主语The youth和动词encourage之间为被动关系,故用被动语态。
9.as　考查固定用法。“as+adj./adv.+as...”为固定用法,表示“和……一样……”。句意:经过六个月激动人心的国际会议和研讨会,当时25岁的Basu找到了她的家——一个和她一样热爱森林的家庭。
10.Deliberately　考查副词。空处在该句中作状语,修饰整个句子,故用副词形式。
