The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on.
Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes(条形码) or designs that cannot be seen.
“The papers can be faxed, scanned(扫描) and reprinted without hidden data disappearing,” New Scientist magazine said last week.
Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model.
The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture.
“Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image,” the magazine said.
Several images that can be hidden in a single picture are scanned into a computer which does the work.
The hidden images or fingerprints cannot be shown until the picture is scanned again.
The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture.
The magazine said that if he model is used for passport checkpoints the picture can be unscrambled(解码) to show the fingerprint or signature and checked against the person holding the passport.
The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier.
The new passport photos will probably contain all EXCEPT _____.

A.one’s picture B.one’s fingerprint
C.one’s signature D.one’s blood type

The writer probably got the information about the new passport photos from ___.

A.Israeli scientists B.a radio or TV C.a newspaper D.a magazine

What is the best title for the passage?

A.A New Computer Technique by Israeli Scientists
B.A New Way t Hide Information
C.The New Passport Photo: More Than Meets the Eye
D.Safe Passport Photos

Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive(漂亮的) people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants (被告). But in the executive (行政的,管理的) circle, beauty can become a liability.
While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman. Handsome male executives were considered as having more honesty than plain(平常的,不漂亮的) men; effort and ability were thought to lead to their success. Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck. All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was connected more to personal relationships and less to ability than that of the attractive overnight successes.
Why are attractive women not thought to be able? An attractive woman is considered to be more feminine and an attractive man more manly than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the "manly" qualities required.
This is true even in politics. "When the only clue is how he or she looks, people treat men and women differently," says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.
The word "liability" most probably means __________.

A.disadvantage B.advantage
C.misfortune D.trouble

In traditionally female jobs, attractiveness ________.

A.makes women look more honest and capable
B.strengthens the qualifies required
C.is of no importance to women
D.often enables women to succeed quickly

Bowman's experiment shows that when it comes to politics, attractiveness _______.

A.turns out to be a disadvantage to men
B.is more of a disadvantage than an advantage to women
C.affects men and women alike
D.has as little effect on men as on women

It can be inferred from the passage that people's views on beauty are often _____.

A.practical B.supportive
C.old-fashioned D.one-sided

I’ve loved my mother’s desk since I was just tall enough to see above the top of it as mother sat doing letters. Standing by her chair, looking at the ink bottle, pens and white paper, I decided that the act of writing must be the most wonderful thing in the world.
Years later, during her final illness, mother kept different things for my sister and brother. “But the desk,” she said again, “is for Elizabeth.”
I never saw her angry, never saw her cry. I knew she loved me; she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.
They never happened. And a gulf opened between us. I was “too emotional(易动感情的)”. But she lived “on the surface”.
As years passed and I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive me.
I posted the letter and waited for her answer, none came.
My hope turned to disappointment, then little interest and, finally, peace. It seemed that nothing happened. I couldn’t be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.
Now the present of her desk told me that she was pleased that writing was my chosen work though she’d never been able to. I cleaned the desk carefully and found some papers inside--a photo of my father and a one-page letter, folded(折叠) and refolded many times.
Give me an answer, my letter asks, in any way you choose, Mother, you always chose the act that speaks louder than words.
The writer began to love her mother’s desk _______.

A.after Mother died
B.before she became a writer
C.when she was a child

The passage shows that _______.

A.Mother was cold on the surface but kind in her heart to her daughter
B.Mother was too serious about everything her daughter had done

The world “gulf” in the passage means _______.

A.deep understanding between the old and the young.

C.free talks between mother and daughter.
D.part of the sea going far in land.

She had never received the letter.
B. For years, she often talked about the letter.
C. She didn’t forgive her daughter at all in all her life.

Students who date (约会) in middle school have significantly worse study skills, are four times more likely to drop out of school and report twice as much alcohol and tobacco use than their single classmates, according to new research from the University of Georgia.
“Romantic relationships are a symbol of adolescence(青春期), but very few studies have examined how adolescents are different in the development of these relationships.” said Pamela Orpinas, study author and professor in the College of Public Health.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires (调查表) about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
“At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit, being well organized, finishing homework, working hard and reading assigned chapters.
“Dating a classmate may have the same emotional complications of dating a co-worker,” Orpinas said, “When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert (转移) attention from studying.”
“Dating should not be considered a ceremony of growth in middle school.”Orpinas concluded.
According to the passage, students who date in middle school may_____.

A.have poorer academic performances
B.be more likely to hurt others
C.enjoy better school lives
D.are less likely to use alcohol and tobacco

When doing his study, Orpinas _____.

A.followed a group of students of 6th and 12th grade
B.found that the students' study skills have connection with their frequency of dating
C.completed questionnaires about the students' academic efforts
D.completed a survey and a report each year

What can possibly happen to the school couples after they break up?

A.They will miss their ex-partners sometimes.
B.They don't want to see each other any longer.
C.Their attention to studying will be affected.
D.They will think it's reasonable to get depressed.

Orpinas’ attitude towards dating in middle school is _____.

A.supportive B.negative
C.indifferent D.positive

We don’t know how different our future will be in the future. We can only try to imagine it.
At first we think about human relationship. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet----even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today----we will feel a little lonely.
Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.
Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.
We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as our health will be in a better condition.
Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine about our future. We should be happy and believe good things will happen.
Why will people probably feel a little lonely in 2050?

A.Because the number of people will become much smaller.
B.Because people won’t communicate with each other much often.
C.Because people won’t like making friends with each other.
D.Because there will be less face-to-face communication.

According to the passage, which of the following will happen in 2050?

A.It won’t be difficult for people to travel to other planets.
B.The way of spending holidays will be the same as that of today.
C.The relationship between people will be more important than today.
D.Our environment will be much more polluted with a growing number of cars.

The underlined word “sanguine” in the last paragraph most probably means ______.

A.disappointed B.optimistic
C.curious D.surprised

What does the passage mainly talk about?

A.How people will communicate in the year 2050.
B.What high technology will appear in the year 2050.
C.How people will travel and spend their holiday in the year 2050.
D.What our life will be like in the year 2050.
