“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

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.

Our “Mommy and Me” time began two years ago.My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down.“I wish I could take one of my children out alone,” said Christie.
Then we worked out a plan: When Christie takes one of her children out, I’ll watch her other three.And when she watches two of mine, I’ll take someone out.
The children were extremely quick to accept the idea of “Mommy and Me” time.Christie’s daughter, McKenzie, went first.When she returned, the other children showered her with tons of questions.McKenzie was smiling broadly.Christie looked refreshed and happy.“She’s like a different child when there’s no one else around,” Christie shared with me quickly.With her mother all to herself, McKenzie didn’t have to make an effort to gain attention.
Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times.For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently.My stuttering(口吃的)son, Tom, doesn’t stutter once during our activities since he doesn’t have to struggle for a chance to speak.And the other son, Sam, who’s always a follower when around other children shines as a leader during our times together.
The “Mommy and Me” time allows us to be simply alone and away with each child —talking, sharing, and laughing, which has been the biggest gain.Every child deserves(应得到)to be an only child at least once in a while.
20.What is the text mainly about?
A.The experience of the only child being with mother.

A.happy B.curious C.regretful D.friendly
22.What is one of the changes the author finds in her children?

It was a winter morning, just a couple of weeks before Christmas 2005.While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work.On arrival, he parked his bike outside the back door as he usually does.After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport.Trevor used it to get to work, putting in 60-hour weeks to support his young family.And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story.Shortly after that, several people in our area offered to help.One wonderful stranger even bought a bike, then called my husband to pick it up.Once again my husband had a way to get to and from his job.It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so.This experience has had a spreading effect in our lives because it strengthened our faith in humanity(人性)as a whole.And it has influenced(影响)us to be more mindful of ways we, too, can share with others.No matter how big or how small, an act of kindness shows that someone cares.And the results can be everlasting.
16.Why was the bike so important to the couple?

I don't think there is anything wrong with your blood. The key to your problem is that long nap(打盹,小睡)after dinner. If you didn't sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn't nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day. You should get out of the habit of sleeping during the evening. Right after your evening meal, engage in some sort of physical activity - a sport such as bowling, perhaps. Or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good nights rest without taking a pill.
  If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up and watch television or do some jobs around your house until you feel sleepy. If you fall asleep and then wake up a few hours later, get up but do not take a sleeping pill. Read a while or listen to the radio, and make yourself a few hours'sleep that night, you will feel better in the morning than you usually feel after taking a pill. The next night you will be ready to sleep at an earlier hour.
  The most important thing is to avoid taking that nap right after dinner and avoid taking pills.
1. According to the writer, it is difficult for you to go to sleep because     .
  A. you get the habit of staying up late B. you haven't taken sleeping pills

In the United States, it is not usual to telephone someone early in the morning. If you telephone early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. So it is with the telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he may think that it’s a matter of life and death. The time chosen for the call communicates its importance.
In social life, time plays a very important part. In the USA guests tend to feel they are not highly regarded if the invitation to a dinner party reaches them only three or four days before the party date. But it is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time is not the same in different cultures that treat time differently; being on time is valued highly in American life, for example. If people are not on time, they may be regarded as impolite or not fully responsible. In the USA no one would think of keeping a business friend for an hour; it would be too impolite. A person who is 5 minutes late is expected to make a shout apology. It he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.

A. the matter is less important B. the matter is too difficult to handle

B. three or four days before the party date in some cultures
C. three or four days before the party date in the USA

The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.
Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world’s first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings. Peale found the animals himself and found a method to make the exhibits more lifelike. The museum’s most popular display was the skeleton (骷髅) of a huge, extinct(灭绝的)elephant, which Peale unearthed on a New York farm in 1801.
Three of Peale’s seventeen children were also famous artists. Paphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many noted people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.
James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.
