“Iris scan (虹膜扫描), please,” the bank’s computer voice tells you. You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match---otherwise, you won’t be able to get your money.
Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics(生物测定学), a fast developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a person’s identity, based on the individual’s unique characteristics, including fingerprints, signature, and so on.
Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose, or steal.
The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone, and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purpose.
For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.
The first paragraph serves as a(n) ________.

A.example B.explanation
C.comment D.conclusion

The underline word “verify” in Paragraph 2 probably means “________”.

A.protect B.confirm
C.develop D.change

Which is the most accurate form of biometrics?

A.The voice scan
B.The fingerprint scan
C.The iris scan
D.The facial scan

What is the author’s attitude towards the future of biometrics?

A.He is uncertain about it.
B.He feels doubtful about it.
C.He is worried about it.
D.He feels hopeful about it.

What is the author’s purpose in writing the text?

A.To explain the importance of identification technology.
B.To discuss the potential of biometrics systems.
C.To introduce the technology of biometrics.
D.To show the advantages of iris scanning.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Last week my youngest son and I visited my father at his new home in Tucson, Arizona he moved there a few years ago, and I was eager to see his new place and meet his friends.
My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him; as a school girl and young adult I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?
The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. In his new home in Arizona, my dad is back to me from where he was.

Wrting artieles about films for The Front Page was my first proper job. Before then I had done bits of reviewing --- novels for other newspapers, films for a magazine and anything I was asked to do for the radio.That was how I met Tom Seaton, the first arts editor of The Front Page, who had also written for television.He hired me, but Tom was not primarily a journalist, or he would certainly have been more careful in choosing his staff.
At first, his idea was that a team of critics should take care of the art forms that didn’t require specialized knowledge: books, TV, theatre, film and radio.There would be a weekly lunch at which we would make our choices from the artistic material that Tom had decided we should cover, though there would also be guests to make the atmosphere sociable.
It all felt like a bit of dream at that time: a new newspaper and I was one of the team.It seemed so unlikely that a paper could be introduced into a crowded market.It seemed just as likely that a millionaire wanted to help me personally, and was pretending to employ me.Such was my lack of self-confidence.
Tom’s original scheme for a team of critics for the arts never took off.It was a good idea, but we didn’t get together as planned and so everything was done by phone.It turned out, too, that the general public out there preferred to associate a reviewer with a single subject area, and so I chose film.Without Tom’s initial push, though, we would hardly have come up with the present arrangement, by which I write an extended weekly piece, usually on one film.
The space I am given allows me to broaden my argument --- or forces me, in an uninteresting week, to make something out of nothing.But what is my role in the public arena? I assume that people choose what films to go to on the basis of the stars, the publicity or the director.So if a film review isn’t really a consumer guide, what is it? I certainly don’t feel I have a responsibility to be ‘right’ about a movie.Nor do I think there should be a certain number of ‘great’ and ‘bad’ films each year.All I have to do is put forward an argument.I’m not a judge, and nor would I want to be.
67.What do we learn about Tom Seaton from the first paragraph?
A.He encouraged Mark to become a writer.
B.He had worked in various areas of the media.
C.He met Mark when working for television.

68.The weekly lunches were planned in order to .
A.help the writers get to know each other
B.provide an informal information session

A.It was unpopular.
B.It wasted too much time.
C.It wasn’t planned properly.
D.It wasn’t put into practice.

At present, in many American cities expecially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of a teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several years.
Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money—the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards.
Unruly students, especially in big cities, large classes and a lack of support from the public in terms of money and understanding have led many public school teachers to leave the profession.
As a result, many of the best students, who would have chosen teaching as their life career in the past, are going into other fields.
Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled.
Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But the change in a vast society like the United States is not easy. People’s attitudes have formed over many years, and sometimes change takes many years.
63.The underlined word “that” in Paragraph 1 refers to “ ”.
A.money B.job
C.secretary D.truck driver
64.What is the present situation of the teaching?
A.Teachers work harder and get underpaid.
B.Teahcers have no opportunities to work in other fields.
C.Teaching can attract best students to work as a teacher.
D.Teaching can provide rewards as well as high salaries.
65.Many public school teachers turn to other professions because .
A.the government doesn’t finacially support them
B.they have to work longer hours than a lawyer
C.their students refuse to listen to them
D.they are not fairly treated
66.The author believes that change in teachers’ status in the United States .
A.is not great
B.is impossible
C.influences people’s attitude
D.needs time

One warm May day, two eighteen – year – old students from San Francisco State College decided to cool off with a swim at Bakers’ Beach. The two students were named Robert Kogler and Shirley O’Neill. They headed out to sea for a distance of 50 metres. Robert was in front.
“Suddenly, I heard him scream,” Shirley recalls. “I looked round and saw this great grey thing going up in the air. The water seemed to be alive.”
Robert sereamed again. “It’s a shark! Get out of here!”
An eye – witness, Army Sergeant Leo P. Day was on guard at the nearby army post. He saw exactly what happened next. “I could see this boy struggling with the shark in the water,” he said. “The sea was red with blood. He was shouting and signalling someone to go back, go back. Then I saw the girl. She was swimming towards him. She completely ignored his warning.”
Shirley reached Robert, and tried to take his hand.
“When I pulled, all I could see was his arm, handing by a thread,” she said.
So she put her arm about Robert’s back, and started to swim towards the shore. She kept praying “Don't’ let it attack again!” That journey to the shore seemed to last for hours. At last, as they neared the shore, a fisherman threw them a line, and pulled them both the rest of the way.
The young man had lost a lot of blood, and died two and a half hours later, From the teeth marks, experts identified the attacker as a Great White Shark.
