To me, cycling at ___ altitude of more than 4,000 meters was _____ unforgettable experience.

A．the; an

B．a(chǎn)n; an

C．/; a

D．a(chǎn)n; /

 

【答案】

：B

【解析】：考查冠詞。第一空用an泛指在海拔超過4000米的地方。第二空指一次令人難忘的經(jīng)歷，unforgettable是以元音開始的，故用an.句意：對(duì)我來說，在海拔4000多米的地方騎自行車是一次令人難忘的經(jīng)歷。故B正確。

When I opened my e-mail the other day, a pretty woman named Rachel appeared on my computer screen. She greeted me by name and started talking with great enthusiasm. Every now and then she stopped to smile at me or blow a kiss. She was reading to me an e-mail from my brother, and a lot of it was about his getting the phone company to give him a high-speed Internet connection. It was pretty cool.

Rache

l was there thanks to a new technology called Facemail. Facemail lets you send e-mail that gets ready to the receiver by an attractive male or female form or by a clown(小丑). The software, which is free, can be downloaded at www. Facemail.com.

Facemail faces are lifelike, and they simulate(模擬) emotions based on emotions that you put in your text. For example, type in-X, and Rachel blows a kiss.

LifeFX, the company that develops the Facemail, is sure there are broad business uses. The reason e-business is not popular, the company says, is that buying over the Internet lacks the human touch. But what if you went to the Nike website and Michael Jordan greeted you by name, waited on you and personally closed the sale? And it is talking with Whirl(惠而浦公司) about using the technology in a computer screen on a fridge. Then if Morn can't be home when the kids get back from school, she can leave a note with voice and image telling them what there is to eat.

Facemail could get hot fast. Personally, I'm a fan. But Facemail should be used with care. The clown looks lively and funny at first. But if you select the clown, put a few rude words in an e-mail and add some angry emotions, you've got a Psycho-mail(瘋?cè)诵碗娮余]件).

The pretty woman that appears on the writer's computer screen was ______.

   A. a woman working on the Internet      B. his brother's girlfriend

  C not a real person                    D. the picture of his pen-friend

   A. you can hire a beautiful woman to read the e-mail to you

   B. you can see the person who sends you the e-mail

   C. yon can send an e-mail free of charge

   D. e-mail can be attractive in a more lovely way

The writer mentioned Nike website and Michael Jordan to show that _______.

   A. Famous people like Michael Jordan also like to use Facemail

   B. Facemail can make shopping on the Internet more interesting

   C. Nike website will increase its sales by Jordan

   D. Michael Jordan will serve you himself on Nike website

B. He thinks it cool and funny.

   C. He thinks it a danger to the Internet.

My first reaction was annoyance. It was Friday afternoon, and I was within an hour of finishing my work for the week. As I was leaving, a nurse brought me one more patient message. The statement read: "Mm. Jones called to say that she has had blurred vision (視覺模糊) ever since her medical test this morning. " I smiled.  Suddenly our tests were causing eye problems.

      This week my patients had questioned everything. My patient with high blood pressure had stopped coming to her treatment on the advice of an Internet chat room. A woman who had a mental problem was substituting ( 用......代替) St. John' s word for her medication. Now Mrs. Jones was imagining problems. I rolled my eyes.

    My second reaction was worry. As I looked through her record, I tried to figure out why she would have blurred vision, but nothing in her record explained the new problem. She' s probably just anxious, I thought. Still, she wouldn't have called if she had been all right. I picked up the phone.

    What 1 next felt can only be described as delight. Before I made the call, the nurse ran in: Mrs. Jones called. Her vision is fine. Turns out she picked up the wrong glasses when she left the office. The X-ray technician has been having the same problem. I let out a lugh. Mrs. Jones had been right. Her vision had been blurred. Now we know why.

Finally I felt shame. I came to realize what Mrs. Jones had taught me. I had first known she was wrong, that her anxiety had clouded hex judgment. Instead, my medical training had clouded mine. Now I feel thankful that Mrs. Jones figured it out before I made a mistake about our relationship. Patients come to me for my help. They pay me to listen, diagnose (診斷), treat and talk. That suggests trust; I must remember that, and trust them too.               

61. The writer smiled while reading the patient message because he knew_____.

A. Mrs. Jones would ask for more tests

B. the patient was being unreasonable

C. the nurse was joking with him

D. Mrs. Jones would call him

62. What has caused Mrs. Jones' eye problem? 

A. Wrong glasses.                                  B. Medical checkup.

C. Her own imagination.                          D. Chatting on the Internet.

63. The underlined words "clouded her judgment" in the last paragraph probably mean_______.           

A. made her less trustful toward the doctor

B. put her in control of her own feelings

C. made her less able to think clearly

D. put her in a dangerous situation
