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 Institute 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 long 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 (数据)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 (差距) 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.
B. the period of the class
C. the attention from teachers
D. the achievements of students
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
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.
B. continuous small classes
C. classroom practices in later grades

opened public school in Philadelphia, US, is believed to be the first in the world to combine innovation
teaching methods with the latest technology. At this school, students work on wireless laptops, teachers
eschew traditional subjects for real-world topics and parents can track their children‘s work on the Internet.
The school, which costs the school district $63 million to build, is free and has no entrance exams.
The 170 ninth-grade students were selected at random from l,500 applicants.
Philadelphia School District Chief Executive Paul Vallas told students they would be observed by other
schools around the world. "You have become instant role models," Vallas said. "People are going to be
watching you."
Students still sit in classrooms, but lessons rely heavily on information found on the Internet and on
interactive software. Students will be allowed to learn at their own pace. Homework is done on the computer
and sent to the teacher for grading and parents can access to the school‘s network to read the teacher’s
feedback on their children’s progress.
Traditional education fails to teach students the skills of problem-solving, critical thinking and effective
communication, which they need to succeed in the 21st century, Principal Shirley Grover said in an interview.
"It‘s not about memorizing certain algebraic equations (代数方程式) and then presenting them in 8 test,"
Grover said. "It’s about thinking how maths might be used to solve a quality of water problem or how it
might be used to determine whether or not we are safe in Philadelphia from the bird flu."
David Terry, 14, said he was hoping to "turn over a new leaf" after discipline problems in his previous
school left him with an "average to really bad" academic record. "This is a great opportunity for me," he said.
"In other schools, I would not _____."

managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever
since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer
Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get
valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press
conference was held at the Venus Institute of Technology.
"We have come to the conclusion, based on last week"s satellite landing," Prof. Zog said, "that there is no
life on Earth."
"How do you know this?" the science reporter of the Venus Evening Star asked.
"For one thing, Earth"s surface in the area of Manhattan is made up of solid concrete and nothing can grow
there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and
nobody could possibly breathe this air and survive."
"What does this mean as far as our flying saucer program is concerned?"
"We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally
planned."
"Are there any other dangers that you discovered in your studies?"
"Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We
don"t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we
send a Venus Being there."
"Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the
water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight
to the saucer."
"If all you say is true, won"t this set back the flying saucer program several years?"
"Yes, but we shall continue as soon as the Grubstart gives us the added funds." Prof. Zog replied.
to _____.
B. the possibility of making a first-rate flying saucer
C. the feasibility of sending a Venus Being to Earth
D. the possibility of directing a flying saucer into Manhattan
their flying saucer program because _____.
B. the Earth"s atmosphere is filled with deadly gases
C. there is a low level of oxygen for Venusians
D. there is no air on the planet of Earth
B. the mass of tiny drops of water floating above Earth
C. the mass of small things moving through the air
D. the dark clouds gathering before a storm breaks
on like this
B. that there is a point in spending billions to land a flying saucer on Earth
C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.
D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth
For some time past it has been widely accepted that babies-and other creatures-learn to do things because
certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely
believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological
(生理的) "drive" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort
of physical comfort, not otherwise.
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with
no reward except the successful outcome.
Paousek began his studies by using milk in the normal way to "reward" the babies and so teach them to
carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a
baby who had enough to drink would refuse the milk but would still go on making the learned response with
clear signs of pleasure. So he began to study the children"s response in situation where no milk was provided.
He quickly found that children as young as four months would learn to turn their heads to right or left if the
movement"switched on a display of lights-and indeed that they were able to learn quite complicated turns to
bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.
Papousek"s light display was placed directly in front of the babies and he made the interesting observation
that sometimes they would turn back to watch the lights closely although they would "smile and bubble" when
the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it
was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a
fundamental human urge to make sense of the world and bring it under intentional control.
B. will meet their physical needs
C. will bring them a feeling of success
D. will satisfy their curiosity
B. would carry out learned movements when it had enough to drink
C. would continue the simple movements without being given milk
D. would turn its head to right or life when it had enough to drink
B. be rewarded with milk
C. please their parents
D. be praised
B. the satisfaction of certain physiological needs
C. their strong desire to solve complex problem
D. a fundamental human urge to display their learned skills

temperature. This helps us decide what to wear. 1 . We want our food to be a certain coldness
in the refrigerator. We want it a certain hotness in the oven. If we don"t feel well, we use a thermometer
to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in
the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the
Fahrenheit scale. But most other countries use the Centigrade scale. Both systems use the freezing and
boiling points of water as their guide. 2 .
The most common kind of thermometer is made with mercury (水银) inside a clear glass tube. As
mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts (收缩). That is
why on hot days the mercury line is high in the glass tube. 3 .
First. Take a clear glass juice bottle that has a cap; fill the bottle with coloured water. Tap a hole in
the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw
(吸管) through the nail hole. 4 .
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the
water lever easily. 5 .
As the temperature goes down, the water will contract, and the lever in the straw will come down.
Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
lives.
B. Thermometers measure temperature, by using materials that change in the same way when they are
heated or cooled.
C. Now that you know this rule you can make a thermometer of your own that will work.
D. The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise
even higher.
E. They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212
degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.
F. Take wax (you may use an old candle if you have one) and melt some of it right where the straw is
struck into the cap to seal (把..粘住) them together.
G. People use thermometers which are made by themselves when travelling around the world.
easy to blame the students in these situations, but the bigger problem is us. We-as parents-are so eager to
shelter our kids that we fail to realize that this in itself is harming them. As the mother of two young sons, I
have to remind myself constantly that the biggest responsibility I have as a parent is to help them develop the
skills needed to live in, to live without me. So, I"ll let them fail.
I"ll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow. And failure梐long with loss, heartbreak, disappointment, etc.-will be part of growth for them. Call me the
anti-tiger mom, but leaving them alone is,my way of helping them become equipped to fit in this world as we
know it today. From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we
expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and
start teaching them how to fish.
My children now are becoming little masters of compromise, but they try to negotiate (协商) everything
now. It"s a small price to help them learn a skill they"ll use for the rest of their lives, including when I don"t
accompany them on job interviews.
B. Because they think they can help them on the questions.
C. Because their kids are too shy to attend interviews.
D. Because their kids strongly request them to do so.
B. Keeping them safe.
C. Leaving them alone.
C. Blaming them.
B. To help them grow in this tough world.
C. To help them develop all social skills.
D. To make them learn to compromise.
B. Let Your Kids Fail
C. Be Eager to Grow Up
D. Live Without Parents
