Once upon a time, on an isolated island in the Java sea, lived short people who dominated(支配, 占優(yōu)勢(shì)) the food chain. Standing no more than three and a half feet tall, these human ancestors hunted giant rats, lumbering lizards（笨拙的蜥蜴), and miniature elephants.  
It sounds a bit like a fairy tale, but it's true. Unearthed relics on the island uncovered the remains of a race of tiny human ancestors. Homo floresiensis, as the newly discovered species has been named, apparently could date back to 13,000 years ago. This means they have a lot in common with modern humans.
So how and why did these people get so small? Scientists suspect that it's due to the fact that this race lived on an isolated island with limited resources. Take the miniature elephants for example. When elephants first came to the island either by swimming or by some kind of natural land raft, they were probably close to full size. But since there wasn't much to eat, over time smaller elephants lived longer and better. The smaller the elephant was, the less it had to eat to stay strong and healthy.
Scientists call this the "island role", and it can apply to humans as well as animals. Given the island's sparse(稀少) food supply, it makes sense that the early humans living there would have evolved (進(jìn)化) a body size requiring less food to survive. So bigger isn't always better.
In the floresiensis, at least, getting smaller was the way to go.
【小題1】According to the passage, the fact Homo floresiensis are very small is based on________.

A．the islanders in the Java SeaB．the human ancestors
C．the unearthed relicsD．a(chǎn) newspaper report
【小題2】 The underlined word "miniature" in the first paragraph most probably means______.
A．tinyB．a(chǎn)ctiveC．rareD．wild
【小題3】People on the island got so small because____________.
A．they did not have enough food to eat.
B．they gradually developed for lack of food.
C．they shared less food with elephants.
D．they remained alive as the elephants.
【小題4】 What might be the most suitable title of the passage?
A．The history of short people
B．Short people from a fairy tale
C．The proofs on short people
D．Short people on an isolated island
【小題5】According to the passage, getting smaller can make people and animals ____
A．run quicklyB．live longerC．live weakerD．run slowly

【小題2】A
【小題3】B
【小題4】D

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(注意). 
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（應(yīng)得到）to be an only child at least once in a while.
【小題1】What is the text mainly about?  

A．The basic needs of children.
B．The advantage of spending time with one child at a time.
C．The happy life of two families.
D． The experience of the only child being with mother.
【小題2】Right after McKenzie came back, the other children were _____________.  
A．happy B．curious C．regretful D．friendly
【小題3】What is one of the changes the author finds in her children?  
A．Tom has less difficulty in speaking.
B．Sam holds her hand more often.
C．The boys become better followers.
D．The daughter acts like a leader.
【小題4】The author seems to believe that ___________.  
A．having brothers and sisters is fun
B．it’s tiring to look after three children
C．every child needs parents’full attention
D．parents should watch others’ children.

The way people hold to the belief that a fun-filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement.
Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure , excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.
【小題1】Raising children, in the author’s opinion, is         .

A．a(chǎn) moral dutyB．a(chǎn) thankless job
C．a(chǎn) rewarding taskD．a(chǎn) source of inevitable pain
【小題2】According to the author, a bachelor resists marriage chiefly because         .
A．he is reluctant to take on family responsibilities
B．he believes that life will be more cheerful if he remains single
C．he finds more fun in dating than in marriage
D．he fears it will put an end to all his fun adventure and excitement
【小題3】To understand what true happiness is, one must         .
A have as much fun as possible during one’s lifetime
B. make every effort to liberate oneself from pain
C. put up with pain under all circumstances
D .be able to distinguish happiness from fun
【小題4】From the last paragraph, we learn that envy sometimes results from         .
A．hatredB．misunderstanding
C．prejudiceD．ignorance
【小題5】.What is the author trying to tell us?
A．How to get happiness
B．Happiness often goes hand in hand with pain
C．The importance of happiness in our lives
D．Happiness equals fun

“People are ruder today because they are rushed and more ‘time poor’ than ever before,” says Patsy Rowe, “ Manners have fallen off the radar(雷達(dá)).” Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.
Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don’t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的）rude messages by email.
However, rudeness is never acceptable. Don’t assume it is OK to be rude if the person you’re in touch with won’t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.
We shouldn’t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more helpful if we’d publicly acknowledge good manners when we see them.
【小題1】What can be inferred from the underlined sentence in Paragraph 1?

A．People can tell good from bad behavior.
B．Radar is able to observe human behavior.
C．People care little about their behavior.
D．Radar can be used to predict human behavior.
【小題2】Some people are less willing to deal with humans because________.
A．they are becoming less patient
B．they are growing too independent
C．they have to handle many important messages
D．they have to follow an evolutionary step backward.
【小題3】The author thinks sending unsigned awful messages is ________.
A．ridiculous B．disgusting C．a(chǎn)cceptable D．reasonable

Your peers are people your age or close to it who have experiences and interests similar to yours. You and your friends make dozens of decisions every day, and you influence each other’s choices and behavior. This is often ________ --- it’s human nature to listen to and learn from other people in your age group.
Sometimes, though, the stresses in your life can actually come from your peers. They may pressure you into doing something you’re uncomfortable with, such as shoplifting, doing drugs or drinking, or taking dangerous risks when driving a car.
The pressure to conform（隨潮流） can be powerful and hard to resist. A person might feel pressure to do something just because others are doing it. Peer pressure can influence a person to do something that is relatively harmless--- or something that has more serious consequences.
People may feel pressure to conform, so they fit in or are accepted, or so they don’t feel awkward or uncomfortable. When people are unsure of what to do in a social situation, they naturally look to others for cues（暗示）about what is and isn’t acceptable.
The people who are most easily influenced will follow someone else’s lead first. Then others may go along, too --- so it can be easy to think, “It must be OK. Everyone else is doing it. They must know what they’re doing.” Before you know it, many people are going along with the crowd --- perhaps on something they might not otherwise do.
Responding to peer pressure is part of human nature --- but some people are more likely to give in, and others are better able to resist and stand their ground.
It’s not always easy to resist negative peer pressure. But when you do, it is easy to feel good about it afterwards. And you may even be a positive influence on your peers who feel the same way --- often it just takes one person to speak out or take a different action to change a situation.
【小題1】Which of the following is a kind of peer pressure?

A．Your teachers give you a lot of homework.
B．Your parents expect high scores from you.
C．Your classmates persuade you to cut class.
D．Your relatives invite you to attend a party.
【小題2】Which is most likely to be filled in the blank in Paragraph 1?
A．negative
B．impossible
C．positive
D．uncertain
【小題3】Most people tend to do what others are doing in order to _________.
A．feel a sense of achievement
B．get a feeling of being accepted
C．set a good example for others
D．stand out in a crowd
【小題4】What can we know according to the author?
A．Giving in to peer pressure is unavoidable.
B．Peer pressure usually leads to serious results.
C．Going along with the crowd usually means making a right choice.
D．Everyone can make a difference by resisting negative peer pressure.
【小題5】This passage is mainly about _______.
A．thoughts on peer pressure
B．different types of peer pressure
C．ways to deal with peer pressure
D．the influence of peer pressure on people

Over time, the custom of kissing developed as a way for adults to express their love and affection for one another. The roots of this form of affection can be traced back to primitive times, when mothers fondled their children, much as mothers do today.
　　Much later, in the sixth century, society apparently accepted the custom of kissing between adults as an expression of their affection. Not surprisingly, France first accepted kissing in courtship (求愛(ài)). There, figure dancing was popular, and each dance was sealed with a kiss.
　　The custom of kissing swept from France through Europe to Russia, where Russian nobility loved to imitate the French. Eventually, the kiss was incorporated into marriage ceremonies, and today lip locks couples into sweet matrimony.
　　The custom of kissing today, as well as in ancient times, serves to pay homage to another.  Early Romans kissed each other on the mouth or on the eyes to greet one another in a manner they thought to be dignified. One Roman emperor even ranked a person's importance by the body part he was allowed to kiss. He allowed important nobles to kiss his lips, less important ones to kiss his hands, and the least important ones to kiss his feet.
In Russia, the highest sign of recognition from the Crown meant a kiss from the Tsar himself. Today, natives of many African tribes pay homage to their Chief by kissing the ground over which he has walked.
【小題1】What’s mainly talked about in the passage?

A．The way to express love and respect. B．The expression of affection.
C．The custom of kissing. D．The function of kissing.
【小題2】Which of the following can best explain the underlined word “homage” in the 4th paragraph？
A．recognition B．respect C．importance D．loyalty
【小題3】It can be learned from the passage that ___________.
A．kissing is a widely accepted way to show love and affection
B．kissing used to be a proper way to show love on the wedding ceremony
C．kissing is a widely accepted way of greeting in the world
D．kissing from the Tsar is only sign of being accepted from the Crown
【小題4】Which of the following is TRUE according to the passage?
A．It was France that made the custom of kissing go to the whole world.
B．Early Africans kissed each other on the mouth or on the eyes to greet one another.
C．One Roman emperor allowed important nobles to kiss his nose.
D．Russian nobility followed the custom of kissing from the French.
【小題5】 We can infer from the passage that __________.
A．mothers created the custom of kissing
B．kissing means differently on different occasions
C．figure dancing was usually sealed with a kiss in Russia

A few months before I was born, my Dad met a stranger who was new to our small town. From the beginning, Dad was fascinated with this enchanting newcomer and soon invited him to live with our family. The stranger was quickly accepted and was around to welcome me into the world a few months later.
As I grew up, I never questioned his place in my family. In my young mind, he had a special position. My parents were complementary instructors：Mom taught me the words, and Dad taught me to obey them. But the stranger... He was our storyteller. He would keep us spellbound for hours on end with adventures, mysteries and comedies(喜劇).
If I wanted to know anything about politics，history or science，he always knew the answers about the past, understood the present and even seemed able to predict the future! He made me laugh, and he made me cry. The stranger never stopped talking, but Dad didn't seem to mind.
I now know that my early concepts about relationship were influenced strongly by the stranger. Time after time, he opposed the values of my parents, yet he was seldom blamed...and NEVER asked to leave.
More than fifty years have passed since the stranger moved in with our family. He has blended(融合) right in but is not nearly as fascinating as he was at first. Still, if you were to walk into my parent's room today, you would still find him sitting over in his corner, waiting for someone to listen to him talk and watch him draw his pictures. His name?
We just call him...“TV”.

The church seems cold this morning, even after all the people, friends and family, fill the benches. I sit here in silence, in shock and denial. This was not supposed to happen. What about our dreams, or our plans? We were going to raise our children, travel the world, and grow old together. I’m only 37, a typical housewife. I don’t know if I can do all this alone—two children, no father. What do I do or say?
The faces of so many people confuse me as they come to pay their last respects. Some have real sorrow; I can see it in their eyes. The others seem to just say, “I told you so.” Those famous last words: I-told-you-so. How I can’t stand them. And the pointing fingers as so-called family and so-called friends pick me out of the crowd for others to see. I want to scream and wake up but I can’t do anything but sit there. How can they be so blind? I fell in love with a man. Love knows no boundaries .
He was a good man, hardworking, caring and kind. He was retired from the Navy and a gentleman. He was sensitive to others’ needs, the kind of man that knew what to do or say, how to humor any situation and calm everyone’s fears. I remember our first child was a big surprise to both of us. I remember when I told him the news. He fell off his chair, saying over and over in disbelief, “But I’m almost sixty.” After a few months he started planning our next and even doing his famous little dance whenever he discussed the idea.
A man, thirty years older than I, lies in a coffin. Flowers, the American flag and his VFW comrades surround him, paying tribute（頌詞）to him as the man he really was. And I sit alone here, with our two children, in silence, praying that this cold morning at church is only a nightmare and I will awake to his loving arms again.
【小題1】What can we know from the passage about the writer?

A．She married a man much older than she.
