Passage Two
My friend Vernon Davies kept birds. One day he phoned and told me he was going away for a week. He asked me to feed the birds for him and said that he would leave the key to his front door in my mailbox. Unfortunately, I forgot all about the birds until the night before Vernon was going to return. What was worse, it was already dark when I arrived at his house. [30]I soon found that the key Vernon gave me could not unlock either the front door or the back door. I was getting desperate. [31]I kept thinking of what Vernon would say when he came back. I was just going to give up when I noticed that one bedroom window was slightly open. I found a barrel and pushed it under the window. As the barrel was very heavy, I made a lot of noise. But in the end, I managed to climb up and open the window. [32]I actually had one leg inside the bedroom when I suddenly realized that someone was shining a torch up at me. I looked down and saw a policeman and an old lady, one of Vernon's neighbors.
"What are you doing up there?" said the policeman.
Feeling like a complete fool, I replied, "I was just going to feed Mr. Davies' birds."12:01 2015-6-12

Questions 30 to 32 are based on the passage you have just heard.
30. Why couldn't the man open the door?
正确答案：A
解析：题目询问男士为什么打不开门。关键是要听到“我很快发现Vernon给我的这把钥匙既开不了前门也开不了后门”，可知是Vernon给错了钥匙，故选A。
31. Why did the man feel desperate?
正确答案：B
解析：题目询问为什么作者感到绝望。关键是要听到“我根本就把喂鸟儿的事给忘了”，“我很快发现Vernon给我的这把钥匙既开不了前门也开不了后门”和“我不断地想Vernon回来之后会说些什么”，由此可知他是怕朋友责怪他，即B。“天黑了”与作者感到绝望没有任何关系，故A不正确；选项C、D的内容文中均未提及。
32. Why did the man feel like a fool?
正确答案：B
解析：作者最终设法爬上去打开了窗户，当他一条腿迈进卧室的时候，突然感觉到有人正用手电筒照向他，他发现是警察和Vernon的邻居。根据他当时的处境可知，警察是不会相信他的。说话人的处境使得他自己都感到很傻，并不是选项A、C、D所说的。
