But what is teacher quality? How can one measure it reliably?
An analysis is issued on a sample of data from a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students’ gains on standardized tests: Mr. Smith is probably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do.
Though this approach is appealing, there are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high there is little room for improvement?
The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable characteristics.
The first finding is that there is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students’ achievement than others.
Second, easily observable characteristics like having a master’s degree or a passing score on the teacher certification exam are not correlated關(guān)聯(lián) with teacher effectiveness.
Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, most teachers hit their stride.
It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early.)
From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time.
The authors also investigate the contentious 有爭議的issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better to a teacher of their own race) or an empathy effect 移情效應(teachers empathize better with students of their own race) or something else entirely.
The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model.
小題1:The schoolmaster could decide wisely whether to further employ the teacher by the end of the ______.
A.the first yearB.the second yearC.the third yearD.the fourth year
小題2:The phrase “hit their stride” most probably means “______”.

At East China University of Science and Technology, students will get a coupon(優(yōu)惠券)if they eat up their food. Students can collect coupons and exchange them for small gifts, such as books, magazines, mobile phone covers and hand warmers.
“It’s been such a surprise,” said Liang Zhaoyun, 19, a student at the university in Shanghai. “It has given us one more motivation to finish our food.”
The measure (措施) is part of a national “eat-up” campaign(行動) which is organized by students to deal with food waste on campuses(校園).
Why only on campuses, you might ask? Because according to a report by Xinhna News Agency, students waste twice as much food as the national average(平均).
The campaign on campus food waste is receiving attention across the country.
“The aim of the campaign is not only to encourage students to finish their food. We hope it can also encourage students to choose a more environment-friendly and healthy lifestyle,” said Tao Siliang, secretary of the Youth League Committee at Shanghai University.
But some school food is poorly prepared, so students do not like to finish it all. Some schools have taken notice of this and they are taking measures to improve it.

All around the world, shoppers flock to Wal-Mart to buy everything.In Texas, they come for another reason: to see the wind turbine(渦輪機) , which supplies 5% of the store's electricity.It along with other facilities, such as exterior walls coated with heat-reflective paint, makes this Wal-Mart a green giant.
The laws of economics suggest that Wal-Mart, with 5, 200 stores worldwide, influences everything including the price of all kinds of goods.It throws its weight behind environmental responsibility, and the impact could be amazing."One little change in product packaging could  save 1, 500 trees," says Wal-Mart CEO Lee Scott."If everybody saves 1, 500 trees or 50 barrels of oil, at the end of the day you have made a huge difference."
Scott wants Wal-Mart to do its part too.He has promised to cut the existing greenhouse-gas emissions (排放) over the next few years and promised to construct new stores that are more efficient.He wants Wal-Mart's fleet (車隊) of more than 7, 000 trucks to get twice as many miles per gallon by 2015.Factories that show Wal-Mart they're cutting air pollution will get preferential treatment in the supply chain. Wal-Mart says it's working with consumer-product manufacturers to  reduce their packaging and will reward them if they do so.
Some people may doubt it is a bid to attract attention from Wal-Mart's controversial labor and health-insurance practices.But it's not just window dressing, because Wal-Mart sees profits in going green.Scott says, "This is a business philosophy, not a social philosophyWe don't go where we don't think there's a great interest in change."
Like Bill Gates, who started his charitable foundation, Scott happens to be promoting Wal-Mart's image at a time when his company's reputation is declining.He acknowledges that he launched the plan partly to shield (保護,庇護) Wal-Mart from bad press about its contribution to global warming." By doing what we're doing today, we avoid the headline risks that are going to come for people who did not do anything," he says."At some point businesses will be held responsible for the actions they take." Meanwhile, should Wal-Mart succeed at shrinking its environmental footprint and lowering prices for green products, both the planet and the company will profit.
小題1:We can infer from the passage that ______.
A.Lee Scott is Wal-Mart's CEO

Recently a Beijing father sent in a question at an Internet forum(論壇) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行話) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!

In order to know a foreign language completely, four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly with confidence  and without hesitation (猶豫). Thirdly, we must be able to write it. We must be able to make sentences that are correct in grammar. There is no short way to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use learning by heart long lists of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must “Learn through use”. Practice is important. We must practise speaking and writing the language whenever we can.

Let us begin by saying what does not cause our dreams. Our dreams do not come from “another world ”. They are not messages from outside source. They are not a look into the future , either .
All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry , or tired or cold , his dreams may include a feeling of this kind .If the covers on your body , such as a quilt or a blanket have slipped off your bed , you may dream that you are sleeping on the ice and snow. The material for the dream you will have tonight is likely to come from the experience you have today.
So the subject of your dream usually comes from something that has effect on you while you are sleeping (feeling of cold, a noise, a discomfort, etc.) and it may also use your past experiences and the wishes and the interests you have now.This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, home-sick soldiers of their families and prisoners of freedom.
To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream , here is the story of the experiment.A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton.He would dream he was in hospital and his charming girlfriend was visiting him , sitting on the bed and feeling gently his hands!
There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean.Their explanations of dreams , though a bit reasonable, is not accepted by everyone but it offers an interesting approach to the problem.They believe that dreams are mostly expressions of wishes that do not come true.In other words, dreams are a way of having your wishes carried out.
小題1:From the passage we know that our dreams ___________.
A.a(chǎn)re imagination of our daily life
B.a(chǎn)re man’s curious look into the future

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有彈性的) to hard and glasslike.
Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障礙).
Two types of chemicals in particular have raised special concern lately. They are called phthalates (鄰苯二甲酸鹽) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (爭議). That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化劑) are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (滲透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.
小題1:What can we know about the plastic from the first paragraph?
A.Its characters and effects.B.Its wide use and bad points.
C.Its importance and chemicals.D.Its popularity and advantages.
小題2:Which of the following products contains BPA?
A.A soft plastic cup.B.A pencil eraser.
C.A baby milk bottle.D.A new perfume.
小題3:Phthalates and BPA can get into us __________.
A.through mouth or noseB.through blood transfusion
C.by feeling plastic productsD.by heating in the microwave
小題4: What is the passage mainly about?
A.A new ban on plastic products.B.Problems caused by the plastic.
C.Good points of the plastic.D.The use of plasticizers.

China is now sending more college students to study in the United States than any other country.  A new report shows a 23 percent increase in the number of Chinese students coming to the U.S.
The latest edition of the annual Institute of International Education(IIE)and another US institute found a 5 percent rise in the number of international university students in the US compared to one year ago. There are now over 157, 000 Chinese students at U.S. colleges and universities.
Aisa accounted for four of the top five countries and regions to take advantage of the US higher education system. “Increased numbers of students from China, particularly at the undergraduate level, largely accounts for the growth this past year,” the report stated. “They really enroll in a full range of US higher education,” said Peggy Blumenthal, senior counselor to the president of IIE, the group that made the report. “20 years ago, students from China only knew of a handful of US insitiutions, but now, they are enrolling in our community colleges, in our small liberal arts institutions, in the research universities. Really spread across the country,” she said.
Chinese mainland was in the number one spot, while India was the number two country of origin. South Korea was third and Canada was number four. China’s Taiwan held the number five spot. Saudi Arabia was in sixth with a 44-percent increase, while Japan was seventh, down 14 percent.
Blumenthal attributes the increase in the number of Chinese students heading to US colleges to limited university places in China, as well as a feeling from students and their parents than they want a “unique” educational experience. China’s family planning policy, says Blumenthal, has also meant that families can concentrated resources on a single child.
The University of California at Los Angeles has one of the largest Asian student populations of any college in the United States.
小題1:Which ranked the third place sharing US higher education?
A.Saudi ArabiaB.South KoreaC.CanadaD.India
小題2:Why is the number of Chinese students going to the US increasing?
A.The US colleges are better than those in China.
B.Each family in China has only one child.
C.China lacks enough educational resources.
D.Chinese students can enter varieties of US colleges.
小題3:Which of the following is right according to Peggy Blumenthal?
A.The number of Chinese students going to the US has increased by 23%.
B.The University of California has contributed to Asian education greatly.
C.Chinese student populations in the US mainly consist of undergraduates.
D.Chinese students know more about US higher education than before.
小題4:The best title for the passage can be           .
A.Chinese College Students Rush to US Schools
B.The Large Number of Chinese Students in the US
C.Chinese Students Make Up Largely Foreign Students in the US
D.Asian Middle School Students in the US Universities
