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.

Last summer holiday, I go to Dalian with my parents. We traveled there on
air. Dalian is a very beautiful and modern city. In morning, we arrived at the hotel.
After breakfast, we began us tour. First, we took a bus to Sea Park. There were such
many different kinds of fish that I couldn’t believe my eye. Then we had lunch in a
restaurant. The seafood, which is well-known, was delicious. After lunch we went
swim. During this trip, we also went to another places of interest. Several days later,
we left for Dalian. We felt very happily. This was the reason why we didn’t feel tired.

A friend and I were standing in line at the grocery store the other day, and I was telling her how lazy my children were．I had come in from work that morning, and like most times, my house was wrecked.
“I believe children nowadays are just out for what they can get．They can never help keep our house clean.” I said, feeling unhappy.
“Do you know how happy you are?” a woman behind us asked．“I would love to go home and find my house a mess．I wouldn’t mind my floor being dirty．Nor would I mind the dirty clothes being piled high．I wouldn’t even mind anyone talking about my dirty home．I would love it．I would love to kick my way through the house just to get to my kids and be able to hug them, kiss them and tell them how much I love them．You see, my two children were killed in an accident． My house stays clean; my clothes stay put up; the dishes are done.”
“There are no fingerprints on my walls．There are no sounds of arguing, either．So you see, you are very lucky．I would give anything to be going through what you are now! How I’d love to be able to hold my kids, wipe away their tears and share their dreams! I wouldn’t care how my house looked．I would be happy just to have them.”
Now if you come into my house and see a big mess, you can think bad thoughts if you want, but I feel greatly blessed.(268 words)

When I first began to work with international students, I asked someone at a lunch, “What brings you here today?” Looking at me like I was a bit crazy, he answered, “ The bus.” That was my first realization that no matter how good a speaker is, there are phrases that will always tend to cause confusion to non-native speakers. These idiomatic phrases(惯用语) add color and interest to any language and are worth learning if you want to talk fluently with native speakers.
“By no stretch”----The speaker is referring to something that’s very hard to achieve or realize, even with great effort, as in “It was not a good meal, by any stretch of the imagination.” Which means that ______________.
“Half dead”----An expression of extreme tiredness, having nothing to do with actual health. Commonly used at the end of a long and tiring day.
“By the book”----This means that an action should follow the rules exactly. It also describes the nature of someone who won’t deviate(背离) from a set of rules no matter what the situation is.
“More power to you”----This isn’t a wish for you to have better electricity from the power company----it’s a statement, usually slightly ironic(讽刺的), that the speaker thinks that you are unlikely to do a task, but you should try if you think you can complete it. It generally means the speaker has no intention of helping you achieve your goal neither will they discourage you from attempting to reach it. For example, “I don’t think you can meet that deadline, but more power to you.”
“As easy as pie”----A reference that something is as simple or easy as eating a delicious dessert, or that it requires little effort to successfully achieve. In chatting, this phrase does not refer to the process of cooking or eating.
【小题1】The example given by the author in the first paragraph is used to show__________.

I once met a middle-aged stranger who said his money had been stolen at the railway station，so he had no money to go home. He begged for help from passers-by，but they all pretended not to have heard what he was saying and went by quickly. Then he stopped me and wanted me to give him the help. At first I could not accept that because I didn't think he was telling the truth. But when I saw tears in his eyes，I began to believe that he might be in the real trouble，so，just immediately I gave him all the money I had. When he took the money， his face turned red. Before he left，he expressed his great thanks and also said he would give back my money when he reached home.
When I came back to school and told my classmates about my story，they held different opinions. Some of them thought that I did a good deed to have given a hand to the person in trouble，while others said that I was cheated. Some even laughed at me and called me a fool who could not judge things in the right way. Now，I am really confused！
