The English language is changing, and you are responsible! Whether we consider changes in grammar, spelling, pronunciation, or the very vocabulary of the language, you have played your part and continue to do so.
When we first learned basic grammar and spelling, perhaps in elementary school, we might have gotten the impression that these things were sacred. The rules that apply to such things might have been presented as unchanging and unchangeable. While this approach might be beneficial for teaching children, it is far from accurate.
The English language, like many others, is a living, growing, ever-evolving thing. Like it or not, you are involved in this change. These changes take many forms. Grammar and spelling have changed radically over the years and centuries, with the spelling differences in different countries today a reflection of this. While the language of a thousand years ago might be called English, most of us would hardly recognize it today as the same language.
The first involves changes in the pronunciation of words. Many are familiar with the differences between the British and American ways of pronouncing certain words. In addition to these differences, the pronunciation of many words has changed over the years because of how you have decided to pronounce them. For example, consider the word "err." The traditional pronunciation of this word rhymes with the word "her." However in recent years, more and more people have been pronouncing it so that it sounds like "air."
Another change in the language involves the addition and removal of words. The makers of dictionaries decide which words deserve to be officially adopted as part of the English language. Through the centuries, many words have come from other languages. In fact, English has probably done this more than any other language in the world, which is why spelling and pronunciation rules for English have so many exceptions.
Of course many slang words have been just short-lived fads that have died out quickly. Others,though, have been adopted by mainstream society and become respectable, as have many technical terms. So then remember, the next time you repeat the newest expression to hit the street, or make up your own words, you may be contributing to the future of the English language.
1.When we begin to learn English, we think .
A.it is interesting to take up a new language

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves(溶解) in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."
1.What can be the best title of the passage?
A.Sea Life Facing Danger B.Climate Change Affecting Seawater
C.Oceans Becoming More Acidic D.Scientist Researching Seawater
2.Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a.Sea life is endangered.
b.CO2 goes into the surface water.
c.The ocean chemistry is affected.
d.CO2decreases the PH and makes the seawater more acidic.
e.CO2 levels in the atmosphere go up.
A. a → b → c → d → e
B. e → b --→ c → d → a
C. a → e -→ b → c → d
D. e → d -→ c → b → a
3.Scientist Robert Dore came to the conclusion based on________ .
A.his research and analysis
B.a major cause of climate change
C.some former theory
D.the expectation of other scientists
4.What does the passage want to tell us most?
A.It takes time to make a scientific study.
B.Atmospheric CO2 is doing harm to sea life.
C.Robert Dore is a committed and serious scientist.
D.Measures should be taken to prevent the potential catastrophe.

A new report says plastics are responsible for $13 billion in damage to the oceans and the undersea environment. The findings were announced recently at a United Nations conference.1..
Plastic thrown away carelessly makes its way into rivers and other waterways. 2.. After a while, it collects in the sea. And plastic never goes away. Plastic is not biodegradable—destroyed by bacteria or natural processes. Instead, it just breaks up into smaller pieces over time. The oceans contain a lot of chemicals and other pollutants(污染物).3..That means harmful material may get into our food supply.
4.. Human beings cause pollution and they can take steps to stop it. They can use fewer single use product containers and throw plastics away correctly. Plastic recycling programs also works—where old bottles and other plastics are collected, broken down and used to make new products. We could reuse bottles in our households many times if we wish to, rather than end it after the first use. We could, when we get rid of that plastic, recycle it and reuse it, which replaces the need for raw materials.
The report also calls on companies to improve methods for using plastics. 5.. And it calls for information about the way plastic is thrown out or removed from use. By putting a new value on plastic, industry has a special reason to clean up the environment.
But all of the companies must join to deal with the problem.
A. Then, fish may eat the plastics.
B. But people can make a big difference.
C. Plastics should be gathered together and reused.
D. It is convenient to use plastic bags in everyday life.
E. It asks for them to better measure and control plastic use.
F. The plastic eventually reaches coastal areas and ocean waters.
G. The report tells about harm to sea life and what might be done to improve the situation.

The following people are expressing their thoughts (1--5) to show their concern for food, environment and so on.After that are pieces of related information (A--F) .Now decide which piece of information would be most suitable for the thought and idea mentioned in questions61---5 and mark your answer letter (A---F) on your answer sheet.There is one extra paragraph which you do not need to use.
______1.How I was struck by the clear water and fresh air in my childhood! But everything has changed, that is, the clear water and fresh air are nowhere to be found again as they were. Above all, a great deal of waste hardly rots away.
______2.More and more people are beginning to have a good knowledge of the importance of a safer and cleaner environment, which in turn forces the business to be cleaned up.
______3.Organic products are getting more and more popular among people, but we should know the fact that organic products might also have something to do with pesticides.
______4.I`m very much fond of growing some vegetables of my own in my small garden, for many vegetables on sale in markets are actually becoming more and more dangerous as a result of widespread pesticides.
______5.Nowadays it is very convenient for consumers to find and buy green food in supermarkets as they are clearly marked.
A."Organic produce is always better, "Gold said."The food is free of pesticides(农药) ,and you are generally supporting family farms instead of large farms.And more often than not it is locally grown and seasonal, so it is more tasty." Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business.
B.Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences - but their knowledge of organic food is far from complete.For example, small amounts of pesticides can be used on organic products.And about three quarters of organic food in Britain is not local but imported to meet growing demand."The demand for organic food is increasing by about one third every year, so it is a very fast-growing market, "said Sue Flock, a specialist in this line of business.
C.Many cities around the world today are heavily polluted.Careless methods of production and lack of consumer demand for environment-friendly products have contributed to the pollution problem.One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.
D.However, today, more and more consumers are choosing "green" and demanding that the products they buy should be safe for the environment.Before they buy a product, they ask questions like these: "Will this shampoo damage the environment?" "Can this metal container be reused or can it only be used once?"
E.Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds.Some supermarket products carry labels(标签) to show that the product is green.Some companies have made the manufacturing(制造) of clean and safe products their main selling point and emphasize it in their advertising.
F.The concern for a safer and cleaner environment is making companies rethink how they do business.No longer will the public accept the old attitude of "Buy it, use it, throw it away, and forget it." The public pressure is on, and gradually business is cleaning up its act.

In the United States, experts are calling for major changes to the admission process in higher education.
The National Center for Educational Statistics (or NCES) reported that U.S colleges and universities received more than million applications between 2013 and 2014 and admitted more than 5 million students. But the problem is not in the number of students, a new report says. The report is called ''Turning the Tide-Making Caring Common. ''
The report argues that the process schools use to choose students causes major problems. David Hawkins is the Executive Director for Educational Content and Policy. He says that most colleges and universities require many things from students when they apply.
Schools usually require an essay describing a student's interests or why they want to study at that school. The schools also ask for letters from teachers describing why a student is a good candidate. But, Hawkins says, schools are most concerned with a student's high school grades and standardized test results.
The Education Conservancy is an organization that fights to make higher education equal and available. Lloyd Thacker is the Executive Director of the Education Conservancy, saying that the college admission process has changed a lot.
''Over the past 30 years, college admissions have become more complex. '' He says that ranking systems for colleges and universities are a big part of the problem.
U.S. News and World Report is a media company that creates a list of what it calls ''America's Best Colleges''. The company bases the list on information collected from colleges and universities across the country. This information includes results of standardized tests like the SAT from all of a school's students. Higher average test results help put schools higher on the list.
Thacker claims, ''Too many students are learning to do whatever it takes in order to get ahead, even if that means sacrificing their own individuality, their health, their happiness and behavior…''
''The impact on students and on parents is that college is all about where you go. The rank has nothing to do with the quality of education that goes on at the college''.
The Harvard report states that the best way to change the admission process is by changing college applications.
1.When choosing students, colleges and universities attach greatest importance to .
A.their teachers' opinion B.their personal interest
C.their academic performance D.their reasons for application
2.The media company ranks the schools on the basis of .
A.peoples' attitude towards the schools
B.employment rate of its graduates
C.the schools' teaching quality
D.information like test results
3.Which of the following does Lloyd Thacker probably agree with?
A.Colleges are supposed to admit more and more students.
B.It is necessary to apply for a proper university by referring to the rank.
C.There is little relationship between colleges rank and the quality of education.
D.The better the applicants grades are, the more likely they will be admitted.
4.Which of the following is the best title of the passage?
A.Higher Rankings Matter a Great Deal
B.Colleges Look to Change Admission Process
C.Colleges Admission Process Makes a Difference
D.Testing Results Determine Students' Fate

Educators across the US are calling for major changes to the admission process in higher education. The National Center for Educational Statistics reported that U.S. colleges and universities received more than 9 million applications between 2013 and 2014. The schools admitted more than 5 million students in that time.
But a new report says that the problem is not about the number of students that are being admitted, but rather how students are selected. The Harvard School of Graduate Education, along with 80 other schools and organizations, released the report in January 2016, called “Turing the Tide---Making Caring Common”. The report argues that the process schools use to choose students causes major problems.
David Hawkins, the Executive Director for Educational Policy, says that most colleges and universities require many things from students when they apply. Schools usually ask for an essay describing a student’s interests or why they want to study at that school. The schools also ask for letters from teachers or other responsible adults describing why a student is a good candidate. But, Hawkins says, the area that schools are most concerned with a student’s high school grades and standardized test results.
The report suggests that paying attention to academic success over other qualities works well for some students but hurts others. In addition, academic success is not the most important quality a student should have. More attention should be paid to showing whether or not a student wants to do good in the world. The report also suggests that schools should ask for evidence that students care about other people. Moving attention away from academic ability will make process less about competition, the report says. Students will feel less stress about meeting higher and higher expectation.
But the report does have its critics. Bob Schaeffer, Public Education Director, said that every few years, someone makes the same argument for change. He said that no real change has happened yet and that even many of the schools that agree with the report still make no changes. “Many of the institutions that have supported the findings in the report are the very institutions that have the most competitive admission processes in the country," Schaeffer said.
1.What is the problem of the admission process according to the report?
A.The schools ask social responsibilities from the applying students
B.The schools attach importance to students’ academic records
C.The number of students getting admitted is too small
D.Admission officers only consider personal qualities
2.Which of the following do colleges ask of applicants except ?
A.Their reasons to attend the school.
B.A description of their interests.
C.Recommendation letters from adults
D.Evidence that students care about others
3.What does the author’s attitude to the report of the admission process?.
A.Supportive. B.Doubtful C.Neutral D.Negative
4.The critic, Bob Schaeffer, thinks that .
A.some schools don't do what they believe is right
B.the largest schools are expected to make changes first
C.not enough schools currently agree with the report
D.history has proved that all changes are good
