答案：
1.【答案】A
【解析】根据下一句及随后的内容，作者讲的是怎样成为动物爱好者的(从小就喜欢动物)，应当选择A.how。
2.【答案】C
【解析】in the first place是固定短语，意思是“首先”。此句意思是：别人经常问到的问题之一，是当初我是如何爱上动物的。
3.【答案】A
【解析】这句话的意思是：作者在呀呀学语之时，最早发清楚的音是“zoo”(动物园),而不是“妈妈”，“爸爸”，因此，应选clarity“清晰”。填入其他选项emotion (感情),sentiment(多愁善感),affection(友爱)不合逻辑。
4.【答案】B
【解析】but在此处连接另一个句子(it was the word“zoo”，“it was”被省略)，表示转折，意为“而是”，Except,except for,but for的用法接近，表示“除了……”。
例如：
We go there every day except Sunday.
He answered all the questions except for the last one.
For a year the dam remained complete but for the generators.
从意思上，逻辑上，都应当选but。
5.【答案】D
【解析】根据后面的over and over again,应选“repeat”
6.【答案】C
【解析】小孩想去动物园，便不停地发出尖叫声，故选“voice”。A shrill voice与scream的意思接近。volume(音量)；noise(噪音)；pitch(音调)均不合要求。
7.【答案】B
【解析】shut s
B.up是指让某人住口，为了让孩子停止尖叫，只好带他去动物园。
8.【答案】A
【解析】根据后面主句的时态，此处只能用一般过去时。
9.【答案】C
【解析】a great many后直接跟可数名词的复数形式；a great / large amount of后跟不可数名词；只有a great /large number of后可以跟可数名词的复数形式。
例如:
I read a great many English books.A large amount of money is spent on obacco every year.
A great number of civilians were murdered in cold bloo D.
10.【答案】D
【解析】living后必须接介词in，意为“居住”；cultivating耕种；reclaiming开垦；只有exploring有探察的意思。
11.【答案】C
【解析】add to相当于increase，增加。其余选项后面都不接to。
12.【答案】A
【解析】later on为固定短语，“后来”。
13.【答案】D
【解析】attendant仆人；keeper可理解为“饲养员”，但是a student keeper容易被误解为“收留学生的人”；aide有“助手”之义。作者一边上学，一边在动物园里打工，只能当助手。
14.【答案】D
【解析】which在此引导定语从句，修饰前面列出的动物。
15.【答案】D
【解析】因为钱是在动物园打工挣的，选successfully更能体现其含义。
16.【答案】D
【解析】finance my first trip意为“支付我的旅行费用”；pay后应接介词for；其他选项的意思相差甚远。
17.【答案】B
【解析】此句为现在完成进行时态，选regularly比较贴切。
18.【答案】D
【解析】此句是由though引导的让步状语从句，应与主句意思相对立。选项中，sorrows和disappointments与主句的appeal to相对立，但sorrows的分量太重。
19.【答案】C
【解析】appeal to为成语，意思是“吸引”。
20.【答案】B
【解析】excursion短途旅行；journey(从一地到另一地的)长距离，具体的旅途；travel旅行，旅游，海外旅行；trip旅行，远足。
