【推荐2】Surfing the Internet for fun will make you a better employee,according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author brent Coker said“Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,”Coker said on the university’s website.”Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself,leading to a higher total Internet attention for a day’s work, and as a result, increase productivity(生产效率),”he said.
　 According to the study of 300 workers ,70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.”Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online, ”said Coker.”that’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation(),or were on the Internet for lee than 20 percent of their total time in the office.”Those who spend too much time surfing the Internet will have a lower productivity than those without,”he said.

【推荐3】When I was about 10, I was walking down the street with my mother. She stopped to speak to Mr Lee. I knew I could see Mr Lee anytime around the neighborhood, so I just stood there. After we passed him, my mother stopped and said something unforgettable, "You let that be the last time you ever walk by somebody you know without opening your mouth to speak, because even a dog can wag its tail when it passes you on the street." That sentence sounds simple but it made me become who I am.

At work, I used to say hello to the president of the company and ask him how our business was doing. But I also spoke to the people in the cafe? and people who cleaned the buildings, and asked them how their children were doing, for every single person deserves to be accepted, no matter how humble (卑微的)they are. I remember that after a few years of passing by the president, I had the courage to ask him for a chat. We had a great talk. At some point, when I asked him how far he thought I could go in his company, he said that if I wanted to, I could get all the way to his seat.

I've become vice president, but that hasn't changed how I treat people. I speak to people wherever I am. Speaking to people creates a pathway into their world, and it lets them come into mine, too. The day you speak to someone who has his head down and then see him lift it up and smile, you will realize how powerful it is just to open your mouth and say hello.

The media provides us with the observations and experience from which we build up our personal understanding of the world and how it works. Much of our view of reality is based on media messages. The media, to a great extent, gives us our sense of reality.

Freedom of the media carries with it certain responsibilities of honesty, fairness, accuracy and accountability. The power of the media to create and destroy human values comes with great responsibility.

The media is powerful in the political system, having a great influence on politics and on forming social change. The power is to decide who will communicate what to whom. Television can greatly influence the election of a national leader on the basis of his or her image.

Professional journalists do have a code of ethics(道德标准). Journalists make a judgement about what’s safe and appropriate to report, which often involves difficult choices. German sociologist Max Weber distinguishes between “ethics of conviction” and “ethics of responsibility”. According to the latter(ethics of responsibility), journalists must take into account the foreseeable consequences of their reporting, and the impact it will have on society. The former, on the other hand, asks journalists to tell the truth, regardless of the consequences. According to Weber, both ideas of ethics should be considered.

Without doubt, information is power, and the big owners of the mass media are very powerful people. Television and radio stations, newspapers, magazines, and websites are, largely, owned and controlled by profit-making businesses. It is not strange that their ideas will get promoted at times.

It is my view that such power and responsibility should never be left in the hands of a few. I believe it is our responsibility as concerned citizens to make sure we are not merely passive viewers, readers or listeners. Together we can have a huge influence on the media by making our views known.

1. What’s the first paragraph mainly about?

A．Responsibilities of the media.	B．Influence of the media.
C．History of the media.	D．Problems of the media.

2. We can learn from the third paragraph that __________.

A．the media is more interested in politics than other fields

B．forming social change is the main duty of the media

C．the great power of the media is controlled by political figures

D．the media can affect politics by forming political figures’ images

3. In the writer’s opinion, citizens should_________.

A．trust the mass media	B．become an influence on the media
C．know how the media works	D．try to report news themselves

【推荐3】A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.

1. What does the underlined word "unaltered" in paragraph 3 refer to?

A．Unchanged.	B．Undivided.
C．Unadopted.	D．Unfinished.

2. Why do mosquito populations have to be controlled?

A．Mosquitoes cause genetic changes in humans.

B．Mosquitoes spread some deadliest diseases.

C．Mosquitoes limit people's ability to reproduce.

D．Mosquitoes make traditional vaccines ineffective.

3. What has been the most successful way of reducing mosquito numbers?

A．Editing genes in female mosquitoes.

B．Sterilizing male mosquitoes before mating.

C．Limiting both genders' reproduction ability.

D．Using pesticides and removing stagnant water.

4. What can we learn from Stephen Dobson's words?

A．The things described in this paper are not practical.

B．A better way of mosquito control is yet to be found.

C．Xi Zhiyong' s method has proven to be very effective.

D．A new tool is needed in order to improve Xi's research.
