The World Health Organization warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.
Indoor air pollution results from the use of dangerous fuels and cook-stoves in the home. To help fight the problem, the WHO announced, new guidelines aimed at reducing household pollutants.
WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking? heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4. 3 million people die from household air pollution given off by simple coal cook-stoves. Most of the deaths are in developing countries.
Carlos Dora is Coordinator in the WHO's Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.
WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia（肺炎）and lung cancer. Women and girls are the main victims. The United Nations found that more than 95 percent of households in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.
Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way.
WHO experts note some new, safe and low-cost technologies that could help are already available. In India, you can buy an induction(电磁) stove for about $ 8.00. And in Africa a you can buy a solar lamp for less than $ 1. 00.

“Don't worry if you have problems!” It is easy to say until you are in the midst of a really big one．The only people who don't have troubles are gathered in little neighborhoods．Most communities have at least one．We call them cemeteries．If you're breathing, you have difficulties．It's the way of life．And believe it or not, most of your problems may actually be good for you! Let me explain．
Maybe you have heard the Great Barrier Reef, stretching some 1,800 miles from New Guinea to Australia．Tour guides regularly take visitors to view the reef．
On one tour, a traveler asked the guide an interesting question．"I notice that the lagoon （泻湖）side of the reef looks pale and lifeless, while the ocean side is vibrant and colorful," the traveler observed．Why is this?
The guide gave an interesting answer, "The coral around the lagoon side is in still water, with no challenge for its survival．It dies early．The coral on the ocean side is constantly being tested by wind, waves and storms．It has to fight for its survival every day．As it is challenged and tested, it changes and adapts．It grows healthy．It grows strong．And it reproduces．"
Then he added, “That's the way it is with every living organism．”
That's how it is with people．Challenged and tested, we come alive! Like coral pounded by the sea, we grow．Physical demands can cause us to grow stronger．Mental and emotional stress can produce tough-mindedness and resiliency．Spiritual testing can produce strength of character and faithfulness．So, you have problems? No problem! Just tell yourself, "There I grow again!"

Robots that can chat，find misplaced glasses，draw aeroplanes and play with your children are attracting thousands of visitors during an expo in Tokyo as Japan adapts to changes in society．
Robots，such as the sound．sensitive Chapit，answer simple questions and even joke with people to help them fight loneliness and stay alert in old age．
Japan has one of the world’s fastest-ageing societies and the government predicts that by 2050 the proportion of people over 65 will reach 40 percent．”Many older people in Japan live alone and have no one to talk to，”said Kazuya Kitamura representative of the expo organizer．“Communication robots accompany people and don’t mind listening to the same stories over and over again．”
Matsumoto’s“Personal Mobility Robot，”equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help elderly move around without pressing buttons．using joysticks(操纵杆)or rotating wheels as in traditional wheelchairs．
The robot can also help find misplaced glasses by identifying them with a sensor．
Other robots，such as the award-winning“DiGRO”can support busy parents who have little time to play with their children．The robot can use the Internet to find a simple image and then draw pictures，keeping children company while parents work．
While Chapit，a relatively simple robot，managed to attract a corporate partner many researchers，such as Kiyoshi Matsumoto，a professor at the University of Tokyo，struggle to attract sponsors for more expensive projects．
“We have developed a robot that can assist many people，but we still haven’t found a sponsor,”said Matsumoto，who added that the cost of the machine，if mass-produced，would be comparable to that of a car．”In the current economic environment there are few companies willing to invest in such a costly project，”he said．It can be inferred from the text that_______．
| A．many children lack love from parents |
| B．robots helpful to the old will be in great demand |
| C．robots are the most useful to children |
| D．robots do better than people in healthcare |
It is difficult to find sponsors for robots because______.

Millions of sports lovers are still thinking about one thing----the Winter Olympics in Sochi Russia. Close to 2900 men and women competed in the 2014 Winter Games about a month ago.
The Olympics brought a lot of attention to Sochi, a city on the Black Sea, which is a popular area for vacation travelers. The area is known for its mild winters.
At least $50 billion was spent on the 2014 Winter Games, making it the costliest Olympics in history. Seven billion dollars was spent on the 2010 Winter Games in Vancouver, Canada. Olympic officials chose Sochi to host the 2014 games almost seven years ago. At that time, Russian President Vladimir Putin said the games would cost about $13 billion. Yet the actual expenses exceeded his estimate. So where did all the money go?
Some observers say the high cost is partly the result of security measures. Brian Jenkins, a terrorism expert from the RAND Corporation, gave the following explanation. There were anywhere between 70,000 and 100, 000 policemen and military troops deployed around the city.
The main threat came from separatist and Islamist groups from the North Caucasus, especially from Chechnya and Dagestan. One group claimed responsibility for two suicide bombings in Volgograd last December. The attacks killed more than 30 people. The city is only about 600 kilometers away from Sochi.
Bruce Hoffman is a terrorism expert from Georgetown University in Washington DC. He says the increased security made Sochi a difficult target for terrorists.
It is thought that the terrorists' intention was to make life difficult for the Russians and to create some sort of incident that would take away the enjoyment.
The last Olympians from around the world on Russian soil were in 1980. That was a year after Soviet troops invaded Afghanistan. More than sixty countries didn’t take part in the Moscow Summer Games to show their anger.According to the passage, why did the Sochi Winter Olympics cost so much?
| A．Because it was held at an area popular for vacation travelers. |
| B．Because the Russian government wanted to make it the best ever held. |
| C．Because security measures at Sochi were stricter than before. |
| D．Because the original plan was made 7 years before. |
It can be known from the passage that Bruce Hoffman was .
| A．a terrorism expert from the USA |
| B．the writer who wrote this article |
| C．an athlete who competed in Sochi |
| D．a terrorism expert from RAND Corporation |
Which of the following is false?
| A．Sochi Olympics cost about 4 times as estimated. |
| B．Next winter Olympics will be held in Vancouver. |
| C．Many countries refused to attend the 1980 Olympics. |
| D．Security is often a problem in international sport games. |
The terrorists might have attacked Sochi Olympics because .
| A．they wanted to make trouble for the Russians |
| B．they thought Russia shouldn't spend so much on sport |
| C．they thought Putin was not a nice president |
| D．they were not interested in winter sports |
Humans aren’t the only ones getting a buzz from coffee．Caffeine can improve memory among honeybees and lead to better pollination(授粉)．According to a recent study published in the journal Science．
The study was conducted by a team of researchers at Newcastle University in the United Kingdom．They found that the nectar(花蜜)of some flowers，such as those from grapefruit and lemon plants，as well as certain coffee flowers，contains low doses of caffeine．To get bees to feed on these flowers，the team trained the insects to associate food with the smell of the flowers．They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine．After 24 hours，the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants．
Professor Geraldine Wright led the researchers．“Remembering floral traits(花部特征)is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are，”Wright said in a statement．
Improved memory led to the better pollination．That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate．This also suggests that caffeine plays a role in improving the bees’ability to search for food．
Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals．“The change is similar to that produced by caffeine in neurons(神经元)associated with learning and memory in the rat brain，”Wright said．
Bee populations have declining since 2007．The dramatic drop in the insects’numbers has serious effects for ecosystems and the farming industry．Bees are needed in the reproduction of crops and spreading wild flower species．Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers．Which of the following is mentioned in the passage?
| A．Caffeine has no effect on the rat brain． |
| B． Bee population has been increasing． |
| C．The nectar of lemon plants contains caffeine． |
| D．Bees dislike nectar from sweetened flowers． |
After reading the passage，John，who works in the farming industry, will probably feel ____________.
| A．annoyed | B．angry | C．nervous | D．excited |
Which of the following relationship is correct according to the passage?
| A．improved memory—caffeine nectar—better pollination |
| B．caffeine nectar—improved memory—better pollination |
| C．improved memory—better pollination—caffeine nectar |
| D．caffeine nectar—better pollination—improved memory |
