Eyeglasses correct many different types of sight problems, including nearsightedness, farsightedness or astigmatism (散光). Trying to understand those different numbers on an eyeglass prescription (驗(yàn)光單) requires understanding the measurements optometrists (驗(yàn)光師) use when fitting you for corrective lenses (鏡片).

Diopters (屈光度)
The numbers on your prescription are given in diopters, whose short form is "D". It is used to measure the focusing power, or amount of correction.
O.S. and O.D.
Optometrists use the Latin short form O.S. and O.D. to distinguish between your eyes. O.S. refers to your left eye, while O.D. refers to the right eye.
Generally, your prescription will show a number for O.S. and O.D. (given in diopters). The farther this number is on a number line from zero, the more correction your eyeglasses should provide. A plus sign means the eye is farsighted, while a minus sign means the eye is nearsighted.
Spherical Value
This plus or minus number for each eye is called the spherical value, or the degree of nearsightedness or farsightedness you have. Its short form is "S."
Cylinder
If you have an astigmatism, the optometrist will also measure its degree. The higher the number (given in diopters) marked as the cylinder of astigmatism, (its short form is "C"), the more astigmatism there is in that eye.
Axis
An astigmatism is also measured in terms of its axis, which is a number between 0 and 180. The axis of the astigmatism does not relate to the amount of cylinder, just the location of the irregularity of the astigmatism on that particular eye.
小題1:According to the first paragraph, various sight problems ______.
A.should be understood by the patients
B.can be avoided by wearing corrective lenses
C.should be tested by different optometrists
D.can be corrected by wearing eyeglasses
小題2:If you need a pair of corrective lenses, the optometrist will first value the numbers of ______.
A.DioptersB.Spherical ValueC.CylinderD.Axis
小題3:From the prescription above we can learn that Li Hua ______.
A.is farsightedB.is nearsighted
C.has no astigmatismD.is normal in sight
小題4:The text is probably taken from ______.
A.a(chǎn)n education reportB.a(chǎn) school bulletin
C.a(chǎn) local newspaperD.a(chǎn)n encyclopedia (百科全書)

Mom was right!If you say thank you,for even the smallest gift or slightest show of kindness,you’ll feel happy.
Gratitude(感謝),says Robert A.Emmons,a professor of psychology at the University of California,is an important element of happiness.In his recent book,Thanks!,Emmons uses the first major study on gratitude to prove mom’s point.In acknowledging and developing this much­ignored expression of thankfulness,he explains how people have benefited—even improved their health.
As one of the leading scholars of the positive psychology movement,he admits gratitude may be difficult to express.He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder.Second,recognize that the source of life’s goodness is more than just you.That source may be your mom,a friend,partner,child,colleague at work or play,or any combination of these.
Gratitude is always other­directed,notes Emmons.You can be pleased or angry with yourself and feel guilty about doing something wrong,but you can never be grateful to or for yourself.
Expressing gratitude shouldn’t be a reaction;it should be a state of mind.To feel grateful when life is a breeze and you have more than you need is easy.To feel grateful in time of crisis—anger,hatred and bitterness—is easier.Also,too many people are aware of life’s blessings only after these are lost.The voices expressing gratitude from his studies of individuals are many.
It’s crisis and chaos—danger,disease,disability and death—that bring many individuals to realize just how dependent they are on others.Yet it’s the way each of us begins life and ends it.It’s too bad that so many people waste those decades in between labouring under the illusion(幻覺) they are self­sufficient,says Emmons.
To enable and embrace gratitude,Emmons encourages the readers of Thanks! to keep a gratitude diary.He even provides easy­to­follow directions on how to practise and develop gratitude.
I’m not a reader or advocate of self­help books,but I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients(接受者).The chance discovery led me to this book.
Mom implied that kindness seems to find its way back to the giver because life really is all about giving,receiving and repaying.So I’ll pay attention to her professional advice and say:Thank you,professor Emmons.
小題1:What is the text mainly discussed?
A.There are many ways of being thankful.
B.Gratitude is important to happiness.
C.Mom is great for her being thankful.
D.Being thankful will keep you fit.
小題2:The author mentions Robert A.Emmons’book Thanks! in order to prove that ________.
A.Professor Emmons supports mom’s study on psychology
B.mom is as great a psychologist as Professor Emmons
C.Professor Emmons is a famous psychologist
D.mom is right about her viewpoint on gratitude
小題3:It will be easier for you to feel grateful when ______.
A.you live a comfortable life
B.you receive gifts on your birthday
C.you get help during your hard times
D.you are congratulated on your success
小題4:What is the opinion of Professor Emmons?
A.It is enough to thank others orally.
B.Whether you are thankful is always up to you.
C.Remember to be thankful anytime and anywhere.
D.It is easier to be thankful for yourself than for others.

It seems hard to watch someone yawn(打哈欠) and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force.
Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don’t develop this deeply rooted behavior until around age four, the study found. Kids with autism (自閉癥) are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect.
"Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did.
"The fact that autistic kids don’t do it might mean they’re really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others’," she added. "Autistic people never seem to understand that."
Like infectious (有感染力的)laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group.
小題1:What does the new study suggest, according to the first two paragraphs?
A.Yawning is a form of communication.
B.It is easy to stop yawning when you see others yawn.
C.Children follow others in yawning just after they are born.
D.Yawning has some mysterious force which is related to God.
小題2:According to Molly Helt, _________.
A.humans differ from animals because they communicate with others
B.yawning is a kind of emotional connection among humans
C.emotions are infectious, but yawning is not
D.yawning helps clear ears on planes
小題3:Which of the following is NOT true about yawning?
A.It is natural to yawn back if people around you yawn.
B.Some kids are too young to yawn after others.
C.Yawning can be used to test children’s development.
D.Kids with autism yawn easily when others yawn.
小題4:The author implies in the last paragraph that ________.
A.yawning is different from infectious laughter and crying in theory
B.it is bad manners to yawn on some social occasions
C.the more you yawn, the happier you will be
D.yawning can make people feel relaxed

Is it necessary for a young man to have an apartment as a prerequisite(先決條件) for marriage? Housing has become a major obstacle(障礙) for Chinese young men hoping to start a family. China may breed a new group of bachelors, men caught in the trap of unaffordable houses.
Since early 2009, the housing market has once again become a hot pot at boiling point. Even with allowance(津貼) and special government policies, home prices in China's first-tier cities such as Beijing and Shanghai are riding the crest(波峰)of a rising wave. According to the "2010 China Marital Status Report" released on Dec 15, 2010, about 70 percent of women interviewed said that housing, a stable income and some savings were the main requirements for marriage.
From the report, we can see that housing is given top priority(優(yōu)先權(quán)) and that women see an apartment as essential(必不可少的) to show that the man is responsible and can provide for his family.
Personality and morals lay outside the top three matrimonial (婚姻的)requirements. Some women and their families hold the traditional position and take it for granted that the home issue should be the man's responsibility, which doesn’t agree with the contemporary independent spirit of women and gender equality. These marriage values reflect the fact that many women consider marriage another form of "social welfare".
Things may be different overseas. Social housing, provided by European authorities, offer the less wealthy people their own piece of real estate. Such housing is usually apartments in tall buildings with 10 or more floors on the outskirts of town, whose main advantage is the low rents.
For many Americans, houses don't pose an obstacle to getting married. They often buy a house after the wedding, because more and more people are reconsidering their real estate worship, and going back to a more rational(理性的) mode of consumption.
In Japan, renting is the custom for newly married young couples. Few young couples can afford to purchase property. Up to 67.1 percent of young couples choose to rent. Generally speaking, renters account for most people younger than 40 in Japan.
Young people should be free to enjoy being young, without the huge pressure of trying to buy property. Society should help create an environment for them to grow up. Don't let the poor bachelor group become a suffering layer(層) of our society.
小題1:Which of the following is Not True according to the text?
A.Home prices have been extremely high since early 2009.
B.In the modern society, women don’t want to be independent.
C.Chinese government has already done something to control home prices.
D.Lots of Chinese young men couldn’t get married because of their economic capability.
小題2:What does the underlined word “outskirts” probably mean?
A.urban areasB.rural areas(鄉(xiāng)下)
C.suburbsD.downtown areas
小題3:Why do many women take housing as one of the main requirements for marriage?
A.Because they can’t afford a house.
B.Because they enjoy their social welfare.
C.Because their families want them to marry men with houses.
D.Because they think it’s a symbol of the men’s sense of responsibility.
小題4:The author uses the examples of European countries, America and Japan to show that __________?
A.new couples in those countries like to rent houses
B.the situation is different in some foreign countries
C.it’s better to live in those countries than live in China
D.their governments have done more than Chinese government
小題5:The last paragraph is mainly about the author’s hope that __________?
A.the society can develop rapidly
B.young people can lead a happy life
C.a(chǎn)ll the young people can afford houses
D.the poor bachelors can become rich and enjoy their life

The interview has been going on for about 20 minutes and everything seems to be going well.Then, suddenly, the interviewer asks an unexpected question, “Which is more important, law or love?”
Job applicants in the West increasingly find themselves asked strange questions like this.And the signs are that this is beginning to happen in China.
Employers want people who are skilled, enthusiastic and devoted.So these are the qualities that any reasonably intelligent job applicant will try to show no matter what his or her actual feelings are.In response, employers are increasingly using the questions which try and show the applicant’s true personality.
The question in the first paragraph comes from a test called the Kiersey Temperament Sorter.It is an attempt to discover how people solve problems, rather than what they know.This is often called aptitude (天資) test.
According to Mark Baldwin of Alliance, many job applicants in China are finding this type of questions difficult.“When a Chinese fills out an aptitude test, he or she will think there is a right answer but they may fail because they try to guess what the examiner wants to see.”
This is sometimes called the prisoner’s dilemma(窘境).Applicants are trying to act cleverly in their own interest, but they fail because they don’t understand what the interviewer is looking for.Remember that in an aptitude test, the correct answer is the honest answer.
小題1:What is the purpose of the passage?
A.To give a piece of advice to job interviewees.
B.To tell you how to deal with job interviews.
C.To advise you how to find a good job.
D.To describe an aptitude test.
