Soaring divorce rates around the globe are taking a toll on the environment, American researchers suggested in a study released on a Monday.

Michigan State University researcher Jianguo “Jack” Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy. They said housing units require space, construction materials and fuel to heat and cool, regardless of the number of inhabitants.

For example, in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water. An additional 38 million extra rooms required heating and lighting that same year due to divorced households.

That costs $6.9 billion in extra utility costs per year, Liu said, plus an added $ 3.6 billion for water, in addition to other costs such as land use.

“A married household actually uses resources more efficiently than a divorced household,” Liu said. He said that in cohabitating(同居) household, people will watch the same television, share the air conditioning and heat and use the same refrigerator. All things use energy at a regularly stable rate, regardless of the number of users.

Liu said he was not condemning divorce, “Some people really need to get divorced.” He said cohabitation—whether by a family or friends—was simply a more environmentally friendly option. Additonally, the researchers noted that trends other than divorce are also changing family living structures, such as the end of multiple generations of a family sharing a home and people remaining single longer.

“People’s first reaction to this research is surprise, and then it seems simple.” Liu said in a press release. “But a lot of things become simple after research is done. Our challenges were to connect the dots and quantify(量化) their relationships. People have been talking about how to protect the environment and fight against climate change, but divorce is a factor that people don’t notice and it needs to be considered”.

He said the increasing energy demands caused by divorce should be considered by governments when they are creating environmental policies.

The research was published in this week’s online edition of the Proceedings of the National Academy of Sciences.

Job interviews never seem easy. To get a job, you may have more interviews than you can count. To succeed in an interview, you should pay attention to the following common mistakes.

Lack of proper preparation. Failure to gather information on the company and the job before the interview makes a very poor impression on interviewers; it suggests that you really are not that interested in the position.

Inappropriate personal appearance. Consider the nature of the position and dress accordingly. When in doubt, dress somewhat more formally than you think would be expected for the job. Be conservative (保守的)and pay attention to details, such as shiny shoes, neat hair, etc. First impressions are very important.

Poor non?verbal communication. In addition to what you are saying, your non?verbal behavior is very important in an interview. Are you making eye contact? Are you listening attentively when the interviewer is speaking? Are you giving a firm handshake when greeted by the interviewer(s)? Are you nervous during the interview? Practice with a friend or in front of a mirror to assess these factors.

Poor attitude. Self?centered behavior (i.e. a “what's in it for me” attitude) is very poorly received by interviewers. Ask yourself what you can contribute to the company? What skills and experience would you bring to the job?

Failure to ask questions. Employers will assess your interest in the company and the position by the types of questions you ask. Proper research prior to the interview will help ensure that the questions you ask are intelligent ones.

Being disorganized. Make sure you arrive at the interview a few minutes early so that you have time to get calm and check your appearance. Arriving late is simply unacceptable, so plan for the unexpected. Always bring an extra copy of your resume (简历) and references to an interview.

Over or under?answering questions. For most interview questions a “Yes” or “No” answer is not appropriate. Provide more details for an employer and cite (引用) examples from personal experience wherever possible. Do not, however, talk endlessly and feel that you have to keep speaking if there's a silence. When you have said what you want to say, stop talking. If you do not understand a question, seek clear explanation before responding.

Failure to send a thank?you note or card following the interview. Take the time to send a thank?you card，which can make an important impact on an employer. Not only does it show your sincere interest in the position, but it also helps make you different from other interview candidates.

For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man’s assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training.

Since natural evolution is extremely slow and mankind’s selective production programs only take a few generations to produce a completely new species, natural evolution has already taken a back seat to mankind’s production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths (猛犸象) probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i»t cause most of the destruction during man’s rule of the world.

Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective (有缺陷的) or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct.

Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize (订制) babies before they are born just like picking options at a car store.

One thing the tour books don’t tell you about London is that 2,000 of its residents are foxes. As native as the royal family, they fled the city about centuries ago after developers and pollution moved in. But now that the environment is cleaner, the foxes have come home, one of the many wild animals that have moved into urban areas around the world.

Several changes have brought wild animals to the cities. Foremost is that air and water quality in many cities has improved as a result of the 1970s pollution-control efforts. Meanwhile, rural areas have been built up, leaving many animals on the edges of suburbs. In addition, urban wildlife refuges (避难处) have been created. The Greater London Council last year spent $750, 000 to buy land and build 10 permanent wildlife refuges in the city. Over 1,000 volunteers have donated money and cleared rubble from abandoned spots. One evening last year a fox was seen on Westminster Bridge looking up at Big Ben.

　　For peregrine falcons (游隼), cities are actually safer than rural cliff dwellings (悬崖栖息地). By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life. That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food.

　　Cities can attract wild animals without turning them harmful. The trick is to create habitats where they can be self-sufficient but still be seen and appreciated. Such habitats can even be functional. In San Francisco, the local government is testing different kinds of rainwater control basins to see not only which ones retain (保持) the cleanest water but which will attract the most birds.

A．Londoners are putting more and more wild animals into their zoos

B．Londoners are happy to see wild animals return to their city

C．Londoners are trying to move wild animals back to the countryside

D．Londoners have welcomed the wild birds, but found foxes a problem

4.What is the passage mainly about?

A．Wildlife returning to large cities.

B．Foxes returning to London.

C．Wild animals living in zoos.

D．A survey of wildlife in New York.

When an NBA player is young he thinks he can win the championship by himself. It is only later when he has aged and been through many battles that he learns an important lesson: there is no “I ” in “team”.

There is no better example of the value of teamwork than the Boston Celtics. Paul Pierce, Ray Allen and Kevin Garnett were all superstars on three different teams. Yet, none of them had any titles to show for it. Then, last season, they decided to sacrifice money and individual statistics to play together. Garnett and Allen joined Pierce on the Celtics and changed the NBA in the process.

It started in simple ways. Garnett and Allen are two of the most intense athletes in the world. They treat every second of every practice like it is the NBA championship. If you want to play alongside them then you will have to do the same. So, the young guys on the Celtics started giving their full effort too.

Pierce had been the star of the Celtics for many years. He used to shoot the ball many times a game. But with the addition of Allen and Garnett he shot less and focused on defense. His selflessness showed the young players that doing what made the team better was the only thing that mattered.

When the Celtics were winning and the game was almost over, Garnett, Pierce and Allen would come out of the game. But they wouldn’t just sit on the bench. Instead, they stood and cheered and screamed for their teammates. They wanted to support their friends and teammates.

Now, the guys who don't play know they can still affect the game by cheering so they scream and cheer when Garnett, Allen and Pierce are playing. The Celtics have developed a strong relationship. They are more than just teammates. They are brothers.

The result: the Boston Celtics won the championship and are considered the favorites to win the Eastern Conference championship again this year.

There is a saying that goes, "A successful team beats with one heart." If that is the case, the Celtics may have the biggest heart in the NBA.

1.What does the passage mainly talk about?

A．The stories of three famous basketball superstars.

B．A famous basketball team named the Boston Celtics.

C．The importance of teamwork among teammates.

D．Matches between the Boston Celtics and other teams.

2.What does this sentence “there is no ‘I’ in ‘team’.” mean in Paragraph 1?

A．"I" will be missing once "I" am on the court.

B．The cooperation of the teammates is more important than the individual.

C．"I" work so hard in a team that "I" will forget who "I" am

D．Surrounded by other players, "I" don’t seem to exist.

3.Which of the following is NOT true about Pierce’s recent performance?

A．He became an even better shooter with others’ help.

B．He focused much more attention on defense.

C．He created more chances for teammates.

D．He stood and cheered for his teammates

4.Which of the following didn’t contribute to the success of the Boston Celtics?

A．The whole team has become devoted to each and every stage of the game.

B．The cooperation and teamwork among the teammates in the match.

C．The influence of Garnett, Allen, Pierce and other teammates’ cheering.

D．The increasing frequency of team players on the bench
