Boys at the top of the pecking order(長(zhǎng)幼次序) either by birth or because their older brothers died score higher on IQ tests than their younger brothers. 
Norwegian researchers now report that it’s a matter of what they call social rank in the family that gives the first born the highest scores or, if the first born had died young, the next oldest. 
Kristensen and Bjerkedal studied the IQ test results of 241,310 Norwegian men drafted(征兵) into the armed forces between 1967 and 1976. All were aged 18 or 19 at the time. 
The average IQ of first-born men was 103.2, they found second-born men averaged 101.2, but second-born men whose older brother died young scored 102.9. And for third-borns, the average was 100.0. But if both older brothers died young,the third-born score rose to 102.6.
The findings provide “evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such.” they concluded.
It’s an issue that has been hotly discussed since at least 1874,when Sir Francis Galton reported that men in noticeable positions tended to be firstborns more often than would have been statistically (統(tǒng)計(jì)) expected.
Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports.
“These two researchers prove that how study participants(參與者) were raised, not how they were born, is what actually influences their IQs,” said Sulloway, an American professor, who was not part of the research team.
“The elder child pulls ahead,” he said, “perhaps as a result of learning gained through the process of tutoring younger brothers and sisters”. 
“The older child benefits by having to organize and express its thoughts to tutor youngsters”, he said, “while the later born children may have no one to tutor.”
【小題1】According to Norwegain researchers’ finding, which of the following is linked to boys’ IQ?

A.Birth orderB.Position in the family
C.Parents’ social rankD.Educational experience
【小題2】What does the sentence “It’s an issue that has been hotly discussed” underlined in Paragraph 6 mean?
A.Many people take interest in IQ study.
B.IQ study has gone further and further.
C.Many people do research on boys’ IQ.
D.Opinions are divided on the conclusion.
【小題3】According to Kristensen and Bjerkedal’s test results, parents can make youngsters smarter by ________.
A.treating them as the oldest child
B.teaching them as the oldest child
C.talking to them as much as possible
D.encouraging them to express thoughts


【小題1】B
【小題2】D
【小題3】A

解析試題分析:文章講述的是一項(xiàng)科學(xué)研究。挪威的研究人員發(fā)現(xiàn),一個(gè)家庭里孩子的IQ的高低與他在兄妹里的排行有關(guān)。這項(xiàng)研究出來以后引起了熱烈的討論。
【小題1】根據(jù)第二段“Norwegian researchers now report that it’s a matter of what they call social rank in the family that gives the first born the highest scores”可知,挪威研究人員認(rèn)為,男孩在家中的排名先后,與IQ有很大的關(guān)系。故選B。
【小題2】根據(jù)下一段“Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports.”可知,從那以后,長(zhǎng)幼順序與IQ的關(guān)系引起了激烈的討論,觀點(diǎn)也產(chǎn)生了分歧,故選D。
【小題3】根據(jù)第五段“The findings provide “evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such.”和最后一段“The older child benefits by having to organize and express its thoughts to tutor youngsters”可知,他們認(rèn)為,男孩的IQ與出生的先后關(guān)系,即長(zhǎng)幼順序有關(guān),長(zhǎng)子從教弟弟妹妹知識(shí)中獲益,故選A。

Read a lot, I mean a lot! You have to increase your ability for reading. Many students are in the habit of reading only when their exams are approaching while some others read only what they are taught or things that must be read because it is in their curriculum. But listen to me now, I am telling you from my own experience that it is a very bad habit and it is not enough to improve your intelligence.
You have to learn and get ready to become versatile in your reading. The fact that you are studying medicine in school does not mean that you should not know one or two things on politics.
Many people have complained to me that they find it hard to read stuffs like novels but I just shake my head in pity for them because it is obvious they have failed to realize the truth in that wise saying by Margaret Fuller that “today a READER, tomorrow a LEADER!”
When you read, you get to “see” so many places and it will be as if you have visited those places in real life. This is because reading will improve your imagination and creativity and understanding. You also get experience from learning about how people dealt with their various problems thereby saving you from going through the pains and difficulties they must have gone through!
Reading will also help you in improving your vocabulary because you will certainly start coming across so many new words which you will try as much as possible to get accustomed to with the help of the dictionary! The good thing about increasing your vocabulary is that it will also improve your thinking ability. After all, we think in words and the more words you know, the easier it will become for you to express yourself or your thoughts.
And when you read, make sure you read so wide because the more you read, the more you know and the more you know the more intelligent you can become.
【小題1】According to the author, what should students do in terms of reading?

A.They needn’t read unless the exams come.
B.They should read books about intelligence.
C.They must read about politics when their major is medicine.
D.They should read as wide as possible.
【小題2】The underlined word “versatile” in Paragraph 2 is closest in meaning to _____.
A.interested B.many-sided C.content D.confident
【小題3】What is the best title for the passage?
A.Increase your ability for reading
B.Read wide and improve your vocabulary

D.Reading makes you a leader tomorrow
【小題4】What is the benefit of knowing more words?
A.You will get used to referring to the dictionary when meeting with new words.
B.You will have less difficulty expressing your opinions.
C.Vocabulary will improve your creativity.

If your preschoolers turn up their noses at carrots or celery, a small reward like a sticker(貼畫) for taking even a taste may help get them to eat previously disliked foods, a UK study said.
Though it might seem obvious that a reward could encourage young children to eat their vegetables, the idea is actually controversial, researchers wrote in the American Journal of Clinical Nutrition. That’s because some studies have shown that rewards can backfire and cause children to lose interest in foods they already liked, said Jane Wardle, a researcher at University College London who worked on the study. Verbal praise, such as “Brilliant! You’re a great vegetable taster”, did not work as well.
The study found that when parents gave their small children a sticker each time they took a “tiny taste” of a disliked vegetable, it gradually changed their attitudes. The children were also willing to eat more of the vegetables—either carrots, celery, cucumber, red pepper, cabbage or sugar snap peas—in laboratory taste tests, the study said.
Researchers randomly assigned (分派) 173 families to one of these groups. In one, parents used stickers to reward their children each time they took a tiny sample of a disliked vegetable. A second group of parents used verbal praise. The third group, where Parents used no special vegetable-promoting methods, served as a “control”.
Parents in the reward groups offered their children a taste of the “target” vegetable every day for 12 days. Soon after, children in the sticker group were giving higher ratings to the vegetables—and were willing to eat more in the research lab, going from an average of 5 grams at the start to about 10 grams after the 12-day experience. The turnaround(轉(zhuǎn)機(jī)) also seemed to last, with preschoolers in the sticker group still willing to eat more of the once-disliked vegetable three months later.
Why didn’t the verbal praise work? Wardle said the parents’ words may have seemed “insincere” to their children.
【小題1】The purpose of writing the passage is      .

A.to show the procedure of an experiment on children’s diet
B.to introduce a practical method of making children eat vegetables
C.to explain why children hate to eat vegetables
D.to present a proper way of verbal praise to parents
【小題2】The underlined word “backfire” in Paragraph 2 probably means “_______”.
A.shoot from behind the back
B.make a fire in the backyard
C.produce an unexpected result
D.a(chǎn)chieve what was planned
【小題3】Which of the following statements is true according to the passage?
A.Most children are born to dislike carrots or celery.
B.Children in the sticker group will never lose interest in eating vegetables.
C.Oral praise works quite well in encouraging children to eat vegetables.
D.It remains a question whether rewarding is a good way to get children to eat vegetables.
【小題4】What can we learn from the last paragraph?
A.Children like rewards, not verbal praise.
B.Parents should give up verbal praise.
C.Children are difficult to inspire.
D.Parents should praise their children in a sincere tone.

Most parents and teachers would get angry when they hear that teenagers listen to their iPods while preparing for exams. But pupils who listen to music when doing their homework may be, in fact, working hard.
Thirty three schools have downloaded specially written pop and rock songs for their 10,000 pupils who are studying for GCSE (初級(jí)畢業(yè)證書). The professionally recorded music, based on texts in English literature, teaches teenagers about themes in the GCSE curriculum (課程). Two young men set up “Revise”, the company that produced the songs, and worked with teachers to make sure the lyrics (歌詞) reflected the curriculum. Some of the songs were written by Geraint Brown, a director, and they are performed by professional singers and musicians.
Songs for the GCSE science and maths lessons are also being developed in 36 schools. They have also started using the program, called, “LearnThruMusic”.
Dave Matthews, the head of Hawthorn High School in the South Wales valleys, said the program aimed at helping teenagers who are unwilling to study. He said, “There are lots of pupils who don’t have a high level of home support. It’s almost cool to say you have no need to find a support and we have got to change that. With this, they don’t have to be sitting at their desk at home. They can be outside, walking around or even listening to it on the bus, which is very convenient for them.” Everyone has a phone, MP3 or CD player, and they’re more likely to listen to these than pick up a book. “I think everyone would agree that music had an important influence on us when growing up. Both boys and girls are very good at remembering the words and dancing to the music in the charts. There’s no one thing that will successfully engage (使…產(chǎn)生興趣) every child, and some of them will make little or no use of this. But the fact that they don’t have to do any extra work makes this a very good deal for a kid,” Dave Matthews added.
【小題1】The pop and rock songs used in 36 schools ________.

A.were written for the students to relax themselves
B.made most parents and teachers angry
C.were specially written for hardworking students
D.were closely related to the curriculum
【小題2】Which benefit of the program is NOT mentioned in the passage?
A.It saves students much extra work.
B.It offers different ways of learning.
C.It makes remembering easier.
D.It improves family support to kids.
【小題3】Which of the following can be inferred in the passage?
A.The program is not expected to have equal effect on every student.
B.Some students used the song as an excuse for not reading textbooks.
C.It’s more difficult to create songs for science and maths lessons.
D.Students involved in the program needn’t go to school every day.
【小題4】Which of the following might be the best title for the passage?
A.Special-written Songs — A Reason Why Students Should Listen to IPods.
B.Special-written Songs — A New Way to Learn the Curriculum.
C.Special-written Songs — A Substitution for Textbooks.

If you planning to study in the United States, you need to consider several factors (因素). Everyone has different opinions about where is the best place to live in. Also, the best places to live in are not always home to the best schools. What’s more, many schools specialize in different areas of study. They Massachusetts Institute of Technology, for example, is a great school for computer science. And if you want to study oceanography, your interests may be better served by attending school in a place which is near the ocean.
Now I will tell you about which states I believe are the best to live in. California is a nice state. Northern California especially has very good weather. As for me, I enjoyed the time I spent in Massachusetts, Virginia and Mary land. These states have a lot of history and culture. The weather is not so perfect as that in California, but is still quite nice. My favourite of America is the Midwest. Middle America, I think, is home to the true American sense of values. Besides, there are many good universities, too.
Also you need to think about your likes and dislikes and then research the different areas. You like sunshine and hate snow? Then you probably won’t like the Midwest or even the Northeast. Open space, nature, peace and quiet? Then you’d better stay away from America’s larger cities. Are you interested in government? Then Washington D.C. is the only place for you. Whatever you decide, put some thought into it.
【小題1】From the first paragraph we can infer that in the USA          .

A.a(chǎn)ll colleges and universities lie in big cities

Science Daily—Kids may roll their eyes when their mothers asks them about their school day, but answering her may actually help them learn. New research from Vanderbilt University reveals that children learn the solution to a problem best when they explain it to their mom.
“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”
Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.
“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
【小題1】According to the passage, a mom had better ________.

A.give a kid some help when he is explaining his problem
B.just listen while a kid is explaining his problem
C.work together with a kid toward the solution to a problem
D.leave a kid alone when he meets a problem at school
【小題2】 If she wants to help a child with his schoolwork, a mom ________.
A.should know the answer to a problem first
B.should pay attention to the child’s feedback.
C.may not know the answer herself
D.should not interrupt the child
【小題3】Who will be the least help to a kid when he is explaining, according to Rittle-Johnson?
A.The kid’s mom.
B.The kid’s grandmother.
C.A peer.
D.A relative the kid doesn’t know.
【小題4】Which of the following best gives the main idea of the passage?
A.Children learn better when their mom is hearing their explaining.
B.Children learn better if they find the solution to a problem themselves.
C.Parents should not provide any assistance to their children’s schoolwork.
D.A mom should listen more to their children when they have problems at school.

We are always told that TV is not good for us. If it is true, how come the TV-addicted kids of our young generation nowadays are much smarter than we are? In my family, the only persons who can work the TV remote control well are the children.
Probably TV really educates us. For example, we can learn a very useful medical fact: A man that has been shot always has time to speak a broken sentence when he is dying. “The killer was…” (dies)
But I suppose the biggest things that we learn from TV can be regarded as “Life Skills”. Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are.
I’ve even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from.
To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn’t worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however, if your name card says “henchman” (幫兇) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
【小題1】 When the writer says “A man that has been shot always has time to speak a broken sentence when he is dying” (Paragraph 2), he shows his________.

A.humor B.sympathy C.deep concern D.medical knowledge 
【小題2】 We can learn from Paragraph 3 that in the real world________.
A.bad things cause people to break down in the rain 
B.bad things never happen on dark and stormy nights 
C.people with emotional problems like to walk in the rain without umbrellas 
D.you can’t hear the crack of lightning and see the accompanying flash exactly at the same time 
【小題3】 On TV what usually happens when a person turns it on?
A.The program shown is always about the importance of TV. 
B.The person always turns off the TV when it’s time for news. 
C.The news shown is always about someone the person knows. 
D.TV always shows news about famous people. 
【小題4】 What’s the main idea of this passage?
A.Life skills can be learned from TV. 
B.What happens in TV is quite different from reality. 
C.Watching TV makes people more creative. 
D.TV plays an important role in society. 
【小題5】 The writer of this passage takes a(n) ________ attitude towards TV plays.
A.positive B.casual C.negative D.indifferent

Online Degrees
Today, you can earn a degree from a major university without ever having sat in one of their classrooms. Many colleges and universities are offering online courses and degree programs now.
Online Learning Programs
With a computer and an Internet connection, you can earn a degree from home, work, or anywhere else for that matter. Online degree programs follow much the same routines as traditional learning, with a few twists. There are lectures, but they won't be in person. There are assignments (作業(yè)) , but you won't hand them to your instructor. In most situations, you are free to "go to class" when it fits your"schedule. If you get a phone call during class, you don't have to miss anything. If you get sick, you don't have to ask for someone's notes, and you just visit the lecture later.
You'll communicate with your instructor by e-mail, chat room and instant messaging. Your  classroom will live in a special software program. Contrary to popular belief, you will have close  contact with other students and the instructor.
Evaluating the Program
There are a lot of questions to ask before you make your selection, such as:
How do students interact with each other?
★Online programs can use chat rooms, instant messaging, teleconferencing, and video conferencing to communicate. The key is to find a program that has this interaction built into it and even requires it.
★What kind of reputation does the school have?
It may seem simple-a good school will have a good online program. This reputation,however, may not be as straightforward as you think. It's not uncommon for a great school to have a weak program or two. So you'd better look at the overall quality of the school and make a judgment.
The Employers' View
As more and more employees get online degrees and use them in the workforce(職場(chǎng)) ,  hiring managers will begin to feel more secure about the quality of education these people have.
【小題1】In which way is online education special?

A.If you get sick, you'll miss the lecture.
B.There are lectures, but you don't need to meet the lecturers.
C.If you get a phone call during class, you will miss something.
D.There are assignments, and you must hand them to your instructor.
【小題2】What is the most important part of online communication?
A.To use e-mails.
B.To look for a program with interaction.
C.To use chat rooms and instant messaging.
D.To use teleconferencing and video conferencing.
【小題3】For whom is the passage probably written?
A.College students.B.Hiring managers.
C.Adult students.D.High school students.
