The term “smog” was first used in London during the early 1900's to describe the combination of smoke and fog. What we typically call “smog” today is a mixture of pollutants but is primarily made up of ground?level ozone (臭氧).

Ozone can be beneficial or harmful depending on where it stays. The ozone staying high above the Earth protects human health and the environment, but ground?level ozone is responsible for the choking, coughing, and painful eyes associated with smog. The ozone in smog also prevents plants growth and can cause widespread damage to crops and forest.

Major smog occurrences often are linked to heavy motor vehicle traffic, high temperatures, sunshine, and calm winds. Weather and geography affect the position and severity of smog. Because temperature regulates the length of time it takes for smog to form, smog can form faster and be more severe on a hot and sunny day. When warm air stays near the ground instead of rising and winds are calm, smog may stay trapped over your city for days. As traffic and other sources add more pollutants to the air, the smog gets worse. Smog is often more severe away from the pollution sources because the chemical reactions that cause smog occur in the atmosphere while the reacting chemicals are being moved by the wind.

Smog is a visible example of air pollution. You can look into the distance during the day to see how much smog there is in the air. In addition, most cities measure the concentrations of pollutants in the air and report the results to the public.

Environmental Protection Agency sets national standards for pollutants. Areas that fail to meet the standards for at least one air pollutant are called “nonattainment (不达标) areas”. New measures are being taken by local governments across the country to reduce air pollution in nonattainment areas. These include: banning charcoal barbecues and wood burning in stoves or fireplaces when pollution levels are high; developing programs to encourage carpooling and voluntary “ozone actions”; limiting traffic in overcrowded areas; expanding or improving public transportation systems; requiring employers to contribute to employee public transportation costs; assessing “smog fees” on cars according to the number of miles driven and vehicle emissions (排放) produced; and even buying and breaking up older “super?dirty” cars.

Real-life Room Escape Games

Real-life room escape games are a type of physical adventure game in which people are locked in a room with other participants and have to use the things in the room to settle a series of puzzles, find clues, and escape the room within a set time limit.

The games are based off Escape the Room video games, such as Crimson Room and QP-Shot, created by TAKAGISM Inc. by Toshimitsu Takagi in 2005, in which the player is locked inside a room and must explore his or her surroundings in order to escape. 1. Other inspirations include adventure board games and movies. Real-life room escape games are becoming popular in the United States, Japan, and China. 2. For example, some games require you escape prison cells while others require you escape space stations.

3. Soon, they were exported to North America, Asia and Australia. Examples include the two pioneer companies Hint Hunt and Adventure Rooms.

The games were so successful that new locations began opening up across China, in cities big and small, according to Want China Times. In the southern city of Shenzhen, for example, the first escape game location opened last August. 4. “These real-life escape games can help those who stay at home on their computers and iPads all day to experience real social circles,” Tian Xiaochuan, who owns two room escape game stores in Jinan, told Want China Times.

Earlier this year, The South China Morning Post said the real-life escape games are a hit among “highly stressed students and overworked young professionals.” 5. Some players get so involved that they tear down equipment or decorations inside their “prisons”, as Zhu Yumeng, chief operating officer of Beijing room escape game store Taoquan told China Daily.

A. Each game adds local themes to settings.

B. And seven new game locations quickly followed.

C. They should also be brave enough to face their fears.

D. Sometimes the excitement becomes a bit much, though.

E. Weekend or day event escape games have been held in some stores.

F. Permanent real life escape games in a fixed location were first opened in Europe.

G. Players must be observant and use their critical thinking skills to escape the room.

The saying “a penny for your thoughts” is an English idiom simply asking people to volunteer their opinions on an issue being discussed. In modern usage, it is often stated as an indirect way of asking what someone is thinking about.

This phrase is basically a proposal (提议), and the speaker is offering to pay to hear the listener's thoughts. It is an idiom, of course, and not meant literally (字面上地) so no real payment generally takes place.

When the saying originated, a penny was worth a lot more than it is in the 21st century.Therefore, “a penny for your thoughts” likely indicated the thoughts were more valuable to those asking the listener for them than they are by today's standards. This loss of value can be used ironically (讽刺地), however, through tone (语气) of voice; it can be used to indicate that someone's idea is bad or worth a penny in modern value.

The phrase is generally credited to a man by the name of John Heywood, who was born sometime just before the 16th century. During his life, he was a writer who penned many plays and a book in 1546, later known as The Proverbs of John Heywood. It is likely that Heywood did not actually come up with the phrase “a penny for your thoughts”. Rather, he was simply the first person to have set the phrase down in written form. The actual origins of the term are unknown, and since his book was simply a collection of common idioms and expressions, it was probably familiar to people in the mid 1500s.

Another phrase similar to “a penny for your thoughts”is offering “your two cents” after making a statement. Someone might give his or her opinion and then say, “that's my two cents,” to indicate the value of his or her idea. While, much like a penny, “two cents” is relatively low in value now, it would have been more valuable at one time and the expression is used in much the same way.

1.When someone says “a penny for your thoughts”, he or she________.

A.wants to ask you for advice

B.considers your thoughts unique

C.is curious about what's on your mind

D.will pay for what you're thinking about

2.The modern meaning of “a penny for your thoughts” ________.

A.is more closely connected to the value of the penny

B.can differ greatly according to a speaker's tone of voice

C.can confuse the listener easily

D.is more popularly accepted

3.In what way is Heywood related to the phrase “a penny for your thoughts”?

A.He came up with it while he was writing.

B.He helped to explain the origins of it.

C.He contributed to the wide use of it.

D.He was the first person to use it.

4.What do we know about the phrase “your two cents”?

A.It is usually used at the end of a statement.

B.It comes from “a penny for your thoughts”.

C.It has witnessed some changes since the 16th century.

D.It is more familiar to people than “a penny for your thoughts”.

Many of the world's countries have reached or are approaching zero population growth (ZPG). Nearly all such lands are economically well developed. They include much of Europe (including Russia), the United States, Canada, Japan, and Australia. As the rate of natural increase (RNI) declines, two things happen. First, the population begins to decline if the loss is not balanced by immigration. Second, a country's population ages because there are fewer births.

Is achieving ZPG good or bad? What happens when a country's population begins to drop? Many people, after all, believe that population decline is a good thing. But is it good for everyone? Does everyone agree?

An aging population can create many problems. Senior citizens require more health care and medical attention. Rather than paying into retirement programs, they begin to draw from their pensions. In the US, the Social Security program, according to many experts, will be used up by 2018. It will pay out more money than it takes in. Additionally, a great number of jobs go begging in search of people willing or able to do them. Many of these jobs are entry?level positions that pay low wages. With an aging population, who will fill them? At the other extreme, some positions require a large number of training and highly specialized skills. Who will fill these positions as retirees leave the workforce?

The answer to the problem of declining and aging population is simple: increased migration. Today many people, particularly those from less developed countries, are migrating in search of employment. Many are willing to take jobs that cannot (or will not) be filled by the_domestic_population. Others are well educated and highly skilled. Both groups contribute to a country's economy progress in many ways. Further, they add to the richness of a country's culture. Of greatest importance, perhaps, is the fact that they have become absolutely necessary to the economy of many lands. As you can see, for many countries and for most immigrants, migration is a win?win situation.

1.In the writer's view, which of the following statements is TRUE?

A.Not everyone agrees that achieving ZPG is absolutely good.

B.Achieving ZPG is every country's aim in spite of its side effects.

C.Achieving ZPG is bad for senior citizens.

D.Achieving ZPG is good for employment.

2.According to the passage, the best way to solve the problem of declining and aging population is ________.

A.to improve the health care system

B.to increase RNI

C.to increase employment

D.to increase migration

3.The underlined words “the domestic population” can be replaced by ________.

A.people within the country

B.people from developing countries

C.people without a college education

D.people living abroad

4.The main idea of the last paragraph is ________.

A.the advantages of increased migration

B.the problem of declining and aging population

C.how to increase migration

D.some ways to enrich a country's culture

Three?dimensional printers are fast becoming everyday devices in the United States. Three?D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue.

Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003. This process is called biofabrication (生物制造). It requires special printing equipment and a special kind of ink.

Traditional printers require ink to produce an image or design on a piece of paper. For their three?D printer, the South Carolina researchers prepare complex nutritious solutions they call bio?inks. Bio?inks are made of proteins and glucose (葡萄糖), which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio?inks are then added to a device that researchers call the Palmetto bio?printer.

Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio?printer, is a great help to the biofabrication process.

The bio?inks are placed in three dispensers (分配器), containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio?ink is released.

Michael Yost is a leader of the research team. He says the printing process is fully automated — machine?operated. He says that the Palmetto bio?printer makes it possible to create complex tissue types.

The researchers say bio?printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs.

But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.

Michael Yost hopes that more people will believe in the benefits of biofabrication.

“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can't touch it, but you will see it and think this is real. And this is really human.”

1.What can we know about the bio?inks?

A.They are the necessities of bio?printing.

B.They only contain proteins and glucose.

C.They can be placed in the traditional printers.

D.They are available in our local drugstores.

2.Which of the following is one of the concerns with biofabrication?

A.Researchers can't find enough living cells of animals to make the bio?inks.

B.The price of the bio?printer is too high and most people can't afford it.

C.Scientists have some difficulty in getting the blood to the replacement tissue.

D.People are worried about the safety of the biofabrication process.

3.According to Michael Yost, we can infer that ________.

A.the Palmetto bio?printer can work without power

B.the Palmetto bio?printer has been used to treat the patients

C.the Palmetto bio?printer can only be found in the United States

D.the Palmetto bio?printer will have a bright future in medical use

4.The passage mainly tells us about ________.

A.the three?D printer and its working principles

B.the bio?inks and their use in bio?printing

C.the spread use of the bio?printer in the USA

D.the growing demand for biofabrication

Parents on South Australia's Aboriginal (澳大利亚土著的) lands may lose some of their financial aid if they do not send their children to school. The new rules draw wide concern.

Mundine is Prime Minister Tony Abbott's top advisor on issues concerning Aboriginals, native Australians. “Now, I know the government needs some necessary measures but I think punishing the parents is really the last choice.” Mr. Mundine says the situation can be changed if the tribal leaders support education. “We need to work with parents and communities because we are making a huge cultural change here.” But other officials say they believe the threat of stopping aid will force families to take education more seriously.

The State of South Australia says it has special programs for Aboriginal children. The students work with their parents and teachers first to develop a personal learning plan and the public schools provide special workers to work individually with Aboriginal students. At the age of seven, Aboriginal students can join a program called Enter for Success designed to attract students to school. The students can choose which high school to attend and receive support in reaching the goals on their individual learning plans.

The State of Western Australia also has special programs for Aboriginal and other ethnic (种族的) groups. The state operates a program called Focus Schools which centers on basic skills like reading, writing and counting. 67% of these public focus schools serve the students in 79 very rural areas. Most of them are primary schools. The Focus Schools program also includes 118 coaches working with students in 134 schools.

1.What's the aim of the new regulations?

A.To develop advanced education.

B.To improve Aboriginal children's school attendance.

C.To get tribal chiefs to support education.

D.To punish parents on South Australia's Aboriginal lands.

2.To change the situation, Mr. Mundine may not agree with ________.

A.cooperating with the parents

B.limiting the economic aid of the families

C.winning the favor of the communities

D.making a cultural change in the communities

3.It is known from the statistics in the last paragraph that ________.

A.the special program is a success

B.the special program covers every area of Australia

C.the government has tried to help with the Aboriginal education

D.the government has taken action to promote the elementary schools
