D
Providing small classes for at least several grades starting in early primary school gives students the best chance to succeed in late grades, according to groundbreaking new research from a Michigan State University scholar.
The research by Spyros Konstantopoulos, a professor of education, is the first to examine the effects of class size over a period and for all levels of students. The study appears in the American Journal of Education.
He is also a member of a group for the Department of Education’s Instiute of Education Sciences that will give official advice on class size to the states. He said the advice will mirror his research: the best plan is to provide continuous small classes(13 to 17 students) for at least several years starting in kindergarten or first grade.
“For a logn time states thought they could just do it in kindergarten or first grade for one year and get the benefits,” He said. “I don’t believe that. I think you need at least a few years in a row where all students, and especially low-achievers, receive the treatment, and then you see the benefits later.”
His research used data from the Project Star study in Tennessee that analyzed the effects of class size on more than 11,000 students in primary and middle school. He found that students who had been in small classes from kindergarten through third grade had actually higher test scores in grades four through eight than students who been in larger classes early on.
Students from all achievement levels benefited from small classes, the research found. “But low-achievers benefited the most, which narrowed the achievement gap with high –achievers in science, reading and math, ” he said.
Although the study didn’t consider classroom practices, he said the reason for the narrowing gap is likely due to low-achieving students receiving more attention from teachers.
“This is especially important in poorer schools because teacher effectiveness matters more in schools with more disadvantaged and low-performing students, ” he said.
48．The professor argues about ________ .
A．the size of the class
B．the period of the class
C．the attention from teachers
D．the achievements of students
49．The result of the research shows that _________.
A．small classes for one year in early grade are enough
B．continuous small classes help students achieve more
C．it’s best to attend small classes in kindergarten
D．small classes do equal good to students of all levels
50．What can we infer from the passage?
A．High achievers will not benefit from small classes.
B．Continuous small classes have not been widely accepted.
C．Low-achievers should be separated from high-achievers.
D．Teachers’ attention matters less than classroom practices.
51．The underlined word “This” in the last paragraph refers to _______.
A．the gap between low and high achievers
B．continuous small classes
C．classroom practices in later grades
D．the Project Star Sturdy

However important we may regard school life to be, we can’t ignore the fact that children spend more time at home than in the classroom. Therefore the great influence of parents can’t be ignored or discounted by the teacher. They can become strong supports of the school or they can consciously or unconsciously prevent the school from accomplishing its aims.
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program and developmental math.
Moreover, the classroom teacher can also play an important role in explaining to parents what they should do. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’ progress, can significantly aid the interchanged of ideas between school and home.
Suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent change his method. He might be persuaded to let Junior participate in discussing he family budget, buying the food, using a measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in math and at the same time, enjoying the work.
Too often, however, teachers’ conferences with parents are devoted to unimportant accounts of children’s wrongdoing, complaints about laziness and poor work habits, and suggestions for punishments and rewards at home.
What is needed is a more creative approach in which the teacher, as a professional advisor, plants ideas in parents’ minds for the best use of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters’ competence.
小题1:The underlined phrase “keep parents apprised of” (Line 1, Para. 2) probably means to let parents .

A．judge

B．know

C．design

D．develop

小题2:What is the purpose of the schools’ informal tea and interviews?

A．To improve the relationship between teacher and parents.

B．To explain to parents the change of the school curriculum.

C．To report students’ misdoings and suggestions for punishments.

D．To help develop good communication between school and home.

小题3:Why does the author provide all example in Paragraph 4？

A．To help parents to know the importance of home activities.

B．To show how the teacher can guide in home training.

C．To prove parents all non professional advisors.

D．To advice parents to teach kids math at home.

小题4:From the passage we learn that the author .

A．thinks teachers should do better as professionals

B．is worried about children’s performance at home

C．is satisfied with the present state of school education

D．believes time spent out of the classroom has been wasted@m

Astronomers (天文学家) say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe.
A top NASA official and other leading scientists say that within four or five years they should discover the first Earth-like planet where life could develop, or may have already. A planet close to the size of Earth could even be found sometime this year.
At the annual American Astronomical Society conference this week, each discovery involving so-called “exoplanets” —those outside our solar system —pointed to the same conclusion：Quiet planets like Earth where life could develop probably are plentiful.
NASA’s Dew Kepler telescope and a lot of new research from the suddenly hot and competitive exoplanet field caused noticeable buzz at the meeting．Scientists are talking abou

t being at “an incredible special place in history” and closer to answering the question. “Are we alone? For the first time, there’s an optimism that sometime in our lifetimes we’re going to get to the bottom of that,” said Simon Worden，an astronomer who heads NASA’s Ames Research Center. “If I were a betting man, which I am, I would bet we’re not alone.”
“These are big questions that reflect upon the meaning of the human race in the universe,” the director of the Vatican Observatory, the Rev. Jose Funes, said Wednesday in an interview at this week’s conference.
Worden told The Associated Press: “I would certainly expect in the next four or five years we’d have an Earth-sized planet in the habitable (可居住的) zone.”
What is very important in determining if we are alone in the unive

rse?
A. Finding an Earth-like planet.       B. Orbiting other stars.
C. Developing new telescopes.      D. Finding more exoplanets.
What’s an exoplanet?
A. It’s a planet like Earth.        B. It’s a planet outside our solar system.
C. It’s a planet orbiting the sun. D. It’s a planet where life have developed.
The underlined phrase “get to the bottom of” probably means “__________”.

A robot is a computer-controlled machine that is programmed to move and handle objects. Robots are able to perform repetitive tasks more quickly, cheaply, and accurately (精确的) than humans. In 1995, about 700,000 robots were used－including over 500,000 in Japan, about 120,000 in Western Europe, and about 60,000 in the United States－all in the industrialized world. Many robots applications are designed for tasks that are either dangerous or unpleasant for human beings. Now, robotic technology can be used in more and more fields. Experts say in the future robots will be able to make new highways, constructsteel frameworks of buildings, clean sewage (污水系统), and such physical work. Besides, another possibility is the development of robotic technology in medical surgery operations.
Perhaps the greatest changes in future robots will improve from their increasing ability to reason. The field of artificial intelligence is moving rapidly from university labs to practical application in industry, and machines of a new kind of robots are being developed, which can perform something involved in the process of understanding and planning, such as the management of a battlefield. Even the control of a large factory will be performed by intelligent computers. And there might be a possibility that these computers can design and make robots of their own.
Is there anything dangerous involved in this artificial intelligence progress then? Robot technology has been making people nervous ever since it was invented. Is it unreasonable to worry that robots will someday become too clever? Is it impossible that these human-like robots will start to think and plan for themselves? Will robots take over the world and force humans to give them energy to survive?

Last week Jay McCarroll and The HSUS(The Humane Society of the United States) made a bold fur-free statement on the runway, marking a new chapter for the fashion industry and animal protection. The encouraging response to McCarroll’s show confirmed that change is happening in fashion.
McCarroll has good reasons for rejecting fur. Each year, tens of millions of animals, including dogs and cats, needlessly suffer and die to fuel the fur industry. But what did Jay McCarroll use in place of fur? “I have patchwork pieces that contain all sorts of combinations of fabrics. The rest is cotton, nylon, polyester . . . you name it. I even have some stuff made out of bamboo/cotton blend. Anything but fur and leather, ”he told Fashion Wire Daily.
“So many people want to protect animals and live their lives without causing unnecessary cruelty. More than two thirds of Americans have pets, and we share a bond with animals every day. Saying no to fur can help millions of animals, and we want to show our respect to leading designers like Jay who embrace compassion as the fashion, ”said Michael Markarian, executive vice president of The HSUS. “It is great to see leaders in the fashion industry recognizing that the animals need their fur more than we do.”

Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It’s hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.
For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely (反过来), boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.
Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex (大脑皮层), enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.
Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore, parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
67．What is the main idea of the passage?
A. Boys tend to pay less attention in class than girls.
B. Girls are better than boys in their ability to detect sounds.
C. Boys and girls behave differently because of biological differences.
D. Single-sex schools are not good because they keep boys and girls separate.
68．Why do girls express negative feelings better than boys?
A. Girls are more emotional than boys.
B. Girls have more brain cells than boys.
C. The amygdala is located in different areas of the brain for boys and girls.
D. The links between certain parts of the brain develop earlier in girls than in boys.
69．Which of the following does the author believe?
A. Girls need more training in communication.
B. Boys and girls should be educated in different ways.
C. Parents should pay more attention to boys.
D. Sex differences should be ignored in education。
70．What does the phase “cling to” in the first paragraph mean?
A. maintain B. abandon C. evaluate D. challenge
