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

Robert Owen was born in Wales in 1771. At the age of ten he went to work. His employer had a large private library so Owen was able to educate himself. He read a lot in his spare time and at nineteen he was given the job of superintendent(监工) at a Manchester cotton mill. He was so successful there that he persuaded his employer to buy the New Lanark mill in Scotland.

When he arrived at New Lanark it was a dirty little town with a population of 2,000 people. Nobody paid any attention to the workers' houses or their children's education. The conditions in the factories were very bad. There was a lot of crime and the men spent most of their wages on alcoholic drinks.

Owen improved the houses. He encouraged people to be clean and save money. He opened a shop and sold the workers cheap, well-made goods to help them. He limited the sale of alcoholic drinks. Above all, he fixed his mind on the children's education. In 1816, he opened the first free primary school in Britain.

People came from all over the country to visit Owen's factory. They saw that the workers were healthier and more efficient than in other towns. Their children were better fed and better educated. Owen tried the same experiment in the United States. He bought some land there in 1825,but the community was too far away. He could not keep it under control and lost most of his money.

Owen never stopped fighting for his idea. Above all he believed that people are not born good or bad. He was a practical man and his ideas were practical. "If you give people good working conditions," he thought, "they will work well and, the most important thing of all, if you give them the chance to learn, they will be better people."

Several southwestern provinces in China are now experiencing the worst drought(旱灾) since the 1950s. The drought has left 18 million people and 11 million farm animals in Yunnan, Guangxi, Sichuan and Chongqing without enough water supplies. And it has affected 5 million hectares of crops in the provinces.

According to China’s Meteorological Administration (中国气象局), the average daily temperature in Yunnan over the past six months has been two degrees higher than normal. And the province has had only half the rainfall of an ordinary year. In Qinglong county, Guizhou, there had been no rain for 268 days until March 25, when it finally rained for three hours.

To ensure the safety of drinking water, local governments have taken emergency action. Workers in parts of Yunnan are drilling (钻空) daily in the hope of digging 1035 wells by mid-May. Among them, 52 have already started working and 288 are under way, providing 20 percent of the required drinking water. Meanwhile, Yunnan province intends to send more migrants (农民工) to work outside the province as the drought worsens. This will not only help to deal with the drinking water shortages, but also increase those farmers’ income. The government will offer free skill training and organize job fairs.

56 The word “This” in paragraph 3 refers to______.

A. the worsening drought

B. the shortage of drinking water

C. sending more migrants to work outside

D. providing 20 percent of the required drinking water

D.Yunnan government offers free skill training and organizes job fairs.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．

Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．

We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired． Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．

1.Which of the following is NOT done by satellites according to the passage?

A. Sending information for weather forecast B. Taking photographs of the Earth

C. Sending TV pictures D. Providing food for airplane pilots

2.What’s the speed the earth rotates at?

A.35,880 kilometers per hour B.335,880 kilometers per hour

C.11,000 kilometers per hour D.110,000 kilometers per hour

3. Which of the following is right according to the passage?

A. There are little rockets on the satellite to put it in the right position every day.

B. Because some satellite use nuclear power, they can crash into each other.

C.A satellite seems to stay in the same place in the sky

D. In order not to move away from its orbit, the satellite puts the rockets in the right position.

4.Which is true of satellites?

A. A satellite usually works for over 10 years．

B. Every time a satellite gets broken，it is brought back to the Earth to be repaired．

C. A broken satellite is never left in space．

D. They often crash into each other．
