“I’m the smartest kid in class.” We all want our kids to be self-confident, but unrealistic perception(認(rèn)知) of their academic abilities, a new study finds, damage a child’s relationship with others in the classroom: The more one student feels unrealistically superior(更好的) to another, the less the two students like each other.

Katrin Rentzsch of Bamberg University in Germany first became interested in the effects of such self-perception when she was studying how people became labeled as nerds(書呆子). “I really got interested in the question of whether it’s OK to boast(吹噓) about achievements,” she says.

This line of thinking led her towards something psychologists call “self-enhancement” －when a person feels unrealistically superior to someone else. So Rentzsch and her colleague Michela Schroder-Abe decided to take a closer look at how such self-enhancement affects relationships, so they turned to the eighth-grade classroom, somewhere they could measure differences between actual academic performance, and social popularity. The 358 students came from 20 eighth-grade classes in schools in southeast Germany.

The researchers asked each student to rate their classmates, in terms of their likability and of their feelings of academic superiority. They then compared those ratings with the students’ grades in math, physics, German and English. Importantly, they conducted the analysis at two different social levels: “habitual”－the way people act in general, and “relationship”－the way someone acts around a specific individual.

In future work, Rentzsch would like to look at these effects on adults, perhaps specifically in team work. She’s also interested in self-enhancement beyond academic achievements, for example physical attractiveness. And another question to explore is why students overestimate their academic abilities. Perhaps it is because of too much praise from their parents or teachers.

1.According to paragraph 1, what should a student do to be more popular in class?

A. Try to love other students.

B. Share with others his achievements.

C. Think highly of others’ academic abilities.

D. Have a correct view of his academic abilities.

2.What was each student required to do during the study?

A. Analyze their relationships with others.

B. Compare themselves with the others.

C. Make assessments about each other.

D. Share their academic performance.

3.The underlined word “it” in the last paragraph refers to .

A. students’ academic abilities.

B. students’ desire to be praised.

C. students’ difficulty in exploration.

D. students’ overestimation of their academic abilities.

4.What would Rentzsch study in the future?

A. The effect of self-enhancement on students.

B. The influence of self-enhancement on adults.

C. The cause of people’s physical attractiveness.

D. The ways of making academic achievements.

In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead, with more tactics(策略).

One tactic involves where to display the goods. For example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food later in their trip. In department stores, the women's shoe section is generally next to the women's cosmetics(化妝品) section: while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over and find some cosmetics they might want to try later.

Besides, businesses seek to appeal to customers' senses, Stores notice that the smell of baked goods encourages shopping, so they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wines went up.

When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decisions in the first few seconds upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the pool through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

1.According to Paragraph 3, which of the following encourages customers to buy?

A. Opening the store early in the morning.

B. Filling the store with the smell of fresh bread.

C. Inviting customers to play music.

D. Displaying British wines next to French ones.

2.What is the California builder's story intended to prove?

A. The house structure is a key factor customers consider.

B. A good first impression increases sales.

C. An ocean view is much to the customers' taste.

D. The more costly the house is, the better it sells.

3.what is the main purpose of the passage?

A. To report researches on customer behavior.

B. To introduce how businesses have grown from the past.

C. To explain how businesses turn people into their customers

D. To show dishonest business practices.

It is interested to look at differences between schools in different countries. In many European countries which the relationship between teachers and students is quite formal, discipline and respect for the teacher is considered as very important. In northern European countries, however, the relationship between teachers and students are more relaxed and much friendly. In America, for example, the relationships are quite formal and the same is true of Britain. Other important difference is whether schools are state schools and private schools. State schools are paid by the government while in private schools, the education of the children is paid for by his parents.

Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher，no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So much more is to be learned outside school by the students themselves.

It is always more important to study by oneself than to memorize some facts or a formula(公式). It is actually quite easy to learn a certain fact in history or a formula in maths. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they worked hard all their lives, wasting not a single moment. They would ask many questions as they read and they did thousands of experiments.

Above all, they knew how to use their brains.

1.The subject which is not spoken of in the article is _____

A. maths B. history

C. psychology D. physics

2.The teacher’s job is to teach ___________.

A. everything the students want to know

科目：高中英語 來源：廣東省2017屆高三第三次模擬考試英語試卷 題型：閱讀理解

You’ll soon be 84 years old, Dad, and you and I will have had 55 Father’s Days together.

You know, there was a time when we were not only separated by the generation gap but completely polarized (對立) by it. Split by: age and experience, opinions, hairstyles, cosmetics, clothing and boys.

The Father-Daughter Duel（沖突） of‘54 shifted into high gear（白熱化） when you taught me to drive the old Dodge and I decided I would drive the‘54 Chevy whether you liked it or not. The police officer who accompanied me home after you reported the Chevy stolen late one evening was too young to understand father-daughter politics and too old to have much tolerance for a 16-year-old. You were so decent about it, Dad, and I think that was probably what made it the worst night of my life.

Our relationship improved greatly when I had babies. I didn’t know what to expect of you and Mom as grandparents but I didn’t have to wait long to find out. Those babies adored you then just as they adore you now.

I suppose I saw our relationship as aging together, rather like a fine wine. But the oddest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn’t immediately occur to me that it was you because the man driving looked so elderly and frail behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.

Fifty years ago this spring, we planted kohlrabi together in a garden in Charles City, Iowa.

This week, we’ll plant kohlrabi together again, perhaps for the last time but I hope not. I don’t understand why planting kohlrabi with you is so important to me but it is. I don’t even like kohlrabi... but I like planting it with you.

Honoring a father on Father’ s Day is about more than a dad who brings home a paycheck, shares a dinner table, and attends school graduation and weddings. It’s more about unconditionally loving children who are stubborn, who know everything and won’t listen to anyone. It’s about loving someone more than words can say, and wishing that it never had to end.

I love you, Dad.

1. What is the purpose of the third paragraph?

A. To prove that the father is very strict.

B. To describe the father-daughter politics.

C. To show the conflict between the author and her father.

D. To condemn the policeman for lack of understanding.

2.What does the author mean by saying “a slap in the face” in the fifth paragraph?

A. She regretted the fights she had with her father.

B. She suddenly realized that her father was so old and could be gone one day.

C. She was ashamed of herself that she hadn’t taken good care of her father.

D. She suddenly realized that she had caused a lot of trouble for her father.

3.Which of the following words can describe the author’s father?

a. Unreasonable b. Caring c. Tolerant d. Stubborn

A. bc B. bd

C. acd D. bcd

4.The author wrote his father this letter to _________.

A. tell him about their conflicts B. say sorry for her being stubborn

C. express her gratitude to him D. remind him of the early incident

Many of us remember being in awe(敬畏) when we saw cloned dinosaurs running wild in the film Jurassic Park. And the idea of using technology to revive(恢復(fù)) extinct species has long fascinated not only writers and directors, but scientists as well.

According to The Telegraph, woolly mammoths(長毛猛犸象), which featured in the popular Ice Age animated movie series, “may walk the earth once more” now that scientists have taken another step toward realizing a long-held dream—recreating their DNA.

Mammoths became extinct around 10,000 years ago. However, since the discovery of near-perfect preserved remains in Arctic permafrost(北極凍土帶) in May 2013, a variety of research studies have been carried out since.

Geneticists from Harvard University analyzed DNA from the remains, looking for genes which separated mammoths from elephants, such as hairiness and ear size. They then used the results to reproduce exact copies of 14 mammoth genes. “It is the first time that mammoth genes have been alive—although so far it has only been done in the lab,” George Church, lead researcher of the project, told the Sunday Times.

Church then used a new technique which allows scientists to edit DNA carefully, replacing sections of elephant DNA with the mammoth genes. So “we now have functioning elephant cells with mammoth DNA in them,” he said.

However, Church ruled out the possibility of bringing the mammoths back to life via cloning from frozen remains. He said he “preferred to focus on rebuilding the full mammoth genome(基因組) by analyzing DNA from preserved remains and putting it into the cells of its closest living relative – the Asian elephant,” reported The Telegraph.

Church argued that the return of the woolly mammoth—or rather, the return of something very similar—could help bring back fragile(脆弱的) ecosystems. However, some scientists believe that bringing back the mammoth would be unethical.

Professor Alex Greenwood, an expert on ancient DNA, said: “We may face the extinction of African and Asian elephants. Why bring back another elephant from extinction when we cannot even keep the ones that are not extinct around?” he told the Sunday Times. “What is the message? We can be as irresponsible with the environment as we want. Then we’ll just clone things back?”

“Money would be better spent focusing on conserving what we do have than spending it on an animal that has been extinct for thousands of years,” he said.

1.We can learn from the article that ______.

A. cloned mammoths followed cloned dinosaurs to get revived

B. the technology to revive mammoth genes is already mature

C. George Church and his colleagues tried to reproduce mammoth DNA

D. Church and his team managed to list all the genes that separate mammoths from elephants

2.According to Church, what is the significance of his study?

A. It could help prevent the extinction of the Asian elephant.

B. It could help people better tell elephant DNA from mammoth genes.

C. It could help bring back some extinct species and save fragile ecosystems.

D. It could help bring mammoths back to life via cloning from frozen remains.

3.The underlined word “unethical” in Paragraph 7 is closest in meaning to ______.

A. unacceptable B. misled

C. impractical D. illegal

4.According to the article, Professor Alex Greenwood believes that _______.

A. there is no need to worry about the extinction of African and Asian elephants at present

B. it’s necessary to bring back species that are beneficial to human beings from extinction

C. the return of the woolly mammoth would help to balance ecosystems

D. it’s more important to protect present species than to bring back extinct ones
