The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria. The World Health Organization estimates that almost 630,000 people died from malaria and malaria-related causes in 2012, most of these cases were in African countries south of the Saharan desert.
In the United States, scientists are seeking new ways to fight malaria. A group of California scientists is working to develop a more effective and less costly substances to protect people from mosquito.
The researchers work at the University of California Riverside. They are investigating the sense of smell in mosquitoes. They found the insects use the same receptor for identifying carbon dioxide in human breath as they do for the smell of our skin.
Anandasankar Ray is leading the investigation. He says scientists tested more than a million chemical compounds until they found a substance called Ethyl pyruvate. He says Ethyl pyruvate makes the mosquitoes' receptor inactive.
"When we apply Ethyl pyruvate to a human arm and offer it to hungry mosquitoes in a cage, then very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out," said Ray.
Genevieve Tauxe is a member of the UC Riverside research team. She says it was not easy to find the neurons of noble cells that recognise both the smell of human breath and skin. She describes a device the researchers are using to examine mosquitoes.
"With this apparatus, we are able to insert a very small electrode into the part of the mosquito's nose, effectively, where its olfactory neurons are and where the smell is happening," said Tauxe.
The scientists use these instruments to look for the signals that a mosquito's neurons send to its brain when it finds an interesting smell. Computer screen images show when the sense is strong or weak.
Anandasankar Ray says a product based on Ethyl pyruvate may cost less to manufacture than DEET, the most effective chemical treatment now in use. He says DEET is too costly for most people who live in areas affected by malaria.
"Perhaps by finding odors that can attack other target receptors, we will be able to improve upon DEET and finally have the next generation of insect behavior control products," said Ray.
The scientists believe they will soon be able to find a way to manufacture less costly and more effective products for the fight against mosquitoes.420

As we move upwards in an organization, our perspective begins to change, sometimes in ways that can feel uncomfortable. Most people begin working in some technical skill area where they can reliably produce desired outcomes based largely on their own performance.
In my career, I was a public relations practitioner, skilled at media relations, drafting news releases, organizing events and news conferences, etc. Of course that also required the skill of collaborating with others, but I wasn’t responsible for their performance. However, as my mastery of public relations increased into the areas of consulting and selling, I started moving up the ladder until eventually I was the general manager of the organization.
Suddenly, I realized I had been catapulted beyond my area of competence. I really had no idea how to “manage” others and how to “delegate” responsibility effectively to other players. So what did I do? I sucked most of the responsibility up to myself, continuing to work on things that demanded my technical expertise, while occasionally handing out a few “tasks” to others. Needless to say I suffered hugely as a manager until I learned the difficult lesson that (as my coach at the time said to me) “You need to find new ways of being important.”
The new role, the “new way of being important” that I learned was the role of leader, orchestrator, delegator. The new role of developing others instead of simply being a technical expert.The new role of working through others, not doing all the work myself. Imagine a symphony orchestra conductor trying to play all the instruments. That is what many new managers find themselves trying to do and its not a highly effective approach, to say the least!
Many new managers fail to achieve their potential because they don’t delegate effectively and they don’t really understand what delegation is all about. Delegating is so critically important that for many aspiring managers it literally becomes their “Achilles Heel”—their fatal weak spot that can make or break their careers. So let’s examine six major reasons that managers fail to delegate effectively.（www.kekenet.com）

The United Nations and the World Meteorological Organization created the Intergovernmental Panel on Climate Change in 1988. The panel is a committee made up of hundreds of scientists. Last week, an IPCC working group released a report about climatic conditions around the world.
Scientists are surer than ever before that the Earth is warming and that human activity is to blame. That is the message of the new report from the Intergovernmental Panel on Climate Change. As we hear from Christopher Cruise, the report's findings will help inform policy makers and the public as they consider action to fight climate change.
One-hundred-ten governments approved this scientific agreement:
"It is extremely likely that human influence has been the dominant cause of observed warming since the mid-20^thcentury."
The head of the World Meteorological Organization, Michael Jarraud, spoke at a press conference about the new report.
"It should serve as yet another wake-up call that our activities today will have a profound impact on society, not only for us, but for many generations to come."
Greenland and Antarctic ice sheets have been losing mass and glaciers continue to shrink, the report says. It calls the decrease of Artic sea ice, "unprecedented," meaning nothing like this has been noted before. The report also examines the mean rate of sea level rise. It says that since the middle of the 19^thcentury, the rate is higher than at any time in the past 2000 years.
The working group also examined the connection between extreme weather events and climate. Brenda Ekwurzel is a climate scientist with the Union of Concerned Scientists, a non-profit group. She has worked with the scientists who prepared the IPCC report.
"The most we can say is that extreme events dealing with coastal flooding and extreme heat, (we have) very, very high confidence with these events being highly linked to climate change."
She says the report blames human activity for half of the increased warming over the past fifty or so years. One such activity is the burning of fossil fuels in factories, buildings and cars. This produces heat-trapping gasses.
Past IPCC reports have led the way to international agreements like the 1997 Kyoto Protocol. It ended in 2012. The United Nation's top climate official, Christiana Figueres, says the new report will help move new climate talks forward.
The Intergovernmental Panel on Climate Change is sometimes criticized as appearing to be too conservative in its predictions. But, Ms. Figueres says this report is right on the mark.
"Everything that we thought we knew about climate change has been underestimated, that we will have much faster and much more intense effects from the growing concentration of greenhouse gases in the atmosphere. So, it's a very sobering message that calls for a more invigorated and more accelerated policy response to address that."
Government leaders and climate experts will get a chance to do that at the climate negotiations next month. The talks will take place in the Polish capital, Warsaw.505
What does the underlined word “sobering”mean in the last paragraph?

A．satisfactory

B．serious

C．disappointing

D．unbelievable

According to the passage, the Earth is warming due to_______.

A．human activity

B．the burning of fossil fuels

C．heat-trapping gasses

D．the burning of fossil fuels in cars

Which of the following statements is true according to the passage？

A．Christopher Cruise says that our activities today will have a profound impact on society.

B．Ms. Figueres says that climate change calls for a more invigorated and more accelerated policy response to address that.

C．Michael Jarraud says that the report blames human activity for half of the increased warming over the past fifty or so years.

D．Brenda Ekwurzel says that It is extremely likely that human influence has been the dominant cause of observed warming since the mid-20thcentury.

A new study finds that more than 13 million deaths could be prevented in China over the next 40 years if the country had stronger anti-smoking measures. But the study's authors say China has not taken many steps to control the use of tobacco. The study was published in the British Medical Journal.
China signed the World Health Organization's international treaty on tobacco control in 2003. But it has not put in place many of the WHO ideas to help people stop smoking. Experts say following these ideas could cut smoking by 40 percent before the year 2050. Without stronger anti-smoking measures, there could be 50 million tobacco-related deaths in the country over that time.The authors of the study used a computer program called "SimSmoke" to make their predictions.
David Levy works at Georgetown University's Lombardi Cancer Center in Washington, DC. He says China has one third of the world's cigarette smokers. More than half of the men in China smoke. Mr. Levy says people often begin smoking without knowing it will harm their health. He says people in some countries smoke because it makes them feel important.
"Smoking, you know, once it gets established and in many of the low- and middle income countries, you know there's a kind of a prestige initially to smoking."
The WHO plan calls for a ban on smoking in all public places. It also calls for countries to place health warnings on cigarette containers and offer programs to help people stop smoking. And, it says, there should be high taxes on tobacco.
Experts say a 75 percent increase in cigarette taxes could save about 3.5 million lives. They say an end to cigarette advertising could save two million lives. After signing the WHO agreement, China placed a 12 percent tax on cigarettes. But the government did not force Chinese smokers to pay the tax.
One of the authors of the new study is Teh-we Hu. He is a professor of public policy economics at the University of California Berkeley. Professor Hu says China's culture and society are changing. He says President Hu Jintao supports a ban on smoking in public. The president also wants people to stop giving cigarettes as gifts to officials and employers. Mr. Hu says the most effective anti-smoking measure in China would be a large increase in the cigarette tax. But he does not expect that to happen soon.
To prevent people from smoking，which is wrong about the WHO plan？

A．The WHO plan calls for a ban on smoking in all public places.

B．The WHO plan calls for countries to place health warnings on cigarette containers.

C．The WHO plan calls for offering programs to help people stop smoking.

If China has stronger anti-smoking measures, about ________ lives could be saved over the next 40 years.

A．3.5 million

B．more than 13 million

C．50 million

D．40 million

What does the underlined phrase “put in place” mean in Chinese?

A．carry out

B．put something in the correct place

C．stop

D．begin

According to the passage, which of the following statements is true?

A．After signing the WHO agreement, China placed a 75 percent tax on cigarettes.

B．Experts say a 12 percent increase in cigarette taxes could save about 3.5 million lives.
