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.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 |
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 |
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. |
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 |
A latest national survey has found that over half of China's netizens are suffering from various mental problems although some 62 percent of them claim at the same time that they are happy on the whole anyway.
This is the result of China's first White Paper on Netizens' Health Conditions issued on Wednesday by 39.net, China's largest authoritative website on health sciences. It is the first most comprehensive health survey on netizens' health situation ever conducted in China in ten years' time. The white paper came out after two months of online and offline research that involved over 150 thousand netizens, covering topics and questions on health knowledge, mental situation, sense of health, and living habits.
According to the white paper, more than 70 percent of China's netizens say they are suffering from mental problems such as bad memory, anxiety, depression, and a lack of confidence. And a similar 72 percent of them also say they are often suffering from diseases like insomnia, dizziness, joint degeneration and achings. Meanwhile, another 53 percent of netizens believe that white collar employees who have bigger work pressures are more likely to catch mental problems.
The white paper adds, doing almost no sports and spending long time surfing online lead to the above mentioned health problems among netizens. Only 9 percent of netizens take up sports on weekends while over 40 percent stay home, surfing. And only 16 percent netizens can assure more than eight hours' sleeping daily.
At present, China has a netizen population of 162 million, with a monthly consumption of 186 yuan, or about 25 dollars, on Internet surfing. The national survey on netizens' health situation ________.
| A．was conducted by sohu.com | B．is conducted every year |

.What’s the main idea of the passage?
| A．China has a large netizen population. |
| B．Many netizens in China have mental problems. |

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team has discovered that subordinate (隶属的)fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding(繁殖) rights within the group, ”explains Marian Wong. “All other group members are non-breeding females, each being 5–10% smaller than its next largest competitor. We wanted to find out how they keep this size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5–10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily，by limiting how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等级的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive(排他的) to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long term health and males regularly prefer females that are fatter than the females’ own ideal.”
When a goby grows to within 5–10% of the size of its larger competitor, it_______.
| A．faces danger | B．has breeding rights |
| C．eats its competitor | D．leaves the group itself |
The underlined words “the evicted fish” in Paragraph 3 refer to _______.
| A．the fish beaten up | B．the fish found out |
| C．the fish fattened up | D．the fish driven away |
The experiment showed that the smaller fish_______.
| A．fought over a feast | B．went on diet willingly |
| C．preferred some extra food | D．challenged the boss fish |
What is the text mainly about?
| A．Fish dieting and human dieting. | B．Dieting and health. |
| C．Human dieting. | D．Fish dieting. |

My students often tell me that they don’t have “enough time” to do all their schoolwork.
My reply is often a brief “You have as much time as the president.” I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.
Once in graduate school, I tried to prove to one of my professors by saying that I was working hard. His answer to me was, “That’s irrelevant (无关的). What’s important is the quality of your work.” Since then I have had time to think carefully about the “hard worker” dodge (诀窍), and I have come to some conclusions — all relevant to the problem of how much time we have.
If you analyze the matter, you can identify two parts of the problem: There is, of course, the matter of “time”, which we can think of as fixed. Then there is the problem of “work” during that time. But, as my professor suggested, it’s not how hard one works but the quality of the product that’s important.
That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office: “Don’t work harder. Work smarter.” There is a lot of sense in that idea.
If you can’t get more time, and few of us can, the only solution is to improve the quality of the work. That means thinking of ways to get more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”, the expression “work habits” should be read as “study habits”.
Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off in all your studies.

Every pet owner loves his pet .There is no argument here.
But when we asked our readers whether they would clone their beloved animals , the responses were split(分裂) almost down the middle . Of the 228 readers who answered it ,108 would clone, 111 would not and nine weighed each side without offering an opinion .
Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and eventual (最终的)sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure (步骤)
Most of the readers who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope that clone could truly recreate a pet; many simply did not wish to go against the natural law of life and death.
Both sides expressed equal love for their animals. More of them owned “the best dog/cat in the world”. They thought of their pets as their “best friend” or “a member of the family”. They told moving stories of pets’ heroism, intelligence and selfless devotion.
No wonder the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
But would cloning reduce the blow? This question seems to be at the heart of this problem.
As far as the cloning of pets is concerned, a recent survey shows that, of all pet owners, .
| A．a lot more of them are for it | B．a lot more of them are against it |
| C．very few of them are willing to tell their opinions ． |
D．about half of them are for it and the other half against it |
The expression “eventual sadness of owning a pet.” (in paragraph 3) refers to .
| A．the death of one’s pet |
| B．the final ownership of a pet |
| C．the troubles one has to deal with in keeping a pet |
| D．the dangers involved in the cloning of a pet |
In spite of their differences on the problem of cloning, it seems that.
| A．all pet owners love their pets very much |
| B．all pet owners try to go against the natural law of life and death |
| C．people who support cloning love their pets more |
| D．people who dislike cloning love their pets more |
From what Gary Kowalski says, we can know that he.
| A．has never thought about the problem of cloning |
| B．thinks it hard to accept the idea of cloning pets |
| C．is in favor of the idea of cloning pets |
| D．is all against the cloning of pets |
