The first sensible lesson is that you shouldn't bother trying to find your way in the dark at all, but just stay put until dawn. Because then you won't trip over things? No, mainly because you'll have an idea of direction. The sun rises in the east. But you will be amazed at how many people forget they know that. Apparently, the area underneath a holly bush provides a good makeshift shelter -- they are thick, and evergreen. The next thing to do -- or rather not to do -- is panic, for the obvious reason that unless there is someone there to hear you scream, it will get you nowhere. Just try to think of nice, happy things. There is always a point in films when a person who is lost in the desert or the snow, dehydrated and exhausted, comes across a set of their own footprints and realizes they have just walked in a huge, round circle. It is wrong to owe it to the unequal strengths or different lengths of your legs. Experiments prove that, without the sun or the moon (or landmarks) as a fixed guide, lots of small errors add up over time so the brain can't correctly identify the "straight ahead" direction. To just get out of somewhere, pick a spot on the horizon and just head for it. There are several ways to find directions in the dark, and by far the best is to establish north using the stars. Most people can identify the Plough, which is part of Ursa Major. It looks a lot like a saucepan. The Plough rotates through the sky, but let's imagine the saucepan lying horizontally , with its handle on the left. You need to trace a line from the star at the right-hand base of the pan, through the star at the right-hand rim , and follow it upwards; the north star is roughly five times the distance between those two "pointer" stars. Then drop a vertical line from the North Star to the horizon and that's north. "Tonight is very cloudy and I can't see the Plough." Maybe luckily, it is quite windy. Keep in mind that almost all of our weather comes from a... Question: If you were lost in Taklimakan Desert in China, _ would NOT be dependable for you to identify the directions. - the sun - the North Star - wind - the moon

According to an international survey by Mercer Human Resource Consulting, a London-based consulting firm, Calgary was put at the top of a list of 144 cities. It scored 121 points, just above Honolulu's score of 120. Helsinki(,) and Ottawa followed at 119.5 and 118.5 respectively. Three other Canadian cities came in the top 20. Montreal and Vancouver tied for ninth and Toronto came in at 18th. The scores are based on air pollution levels, availability and quality of hospitals and medical supplies, as well as the efficiency of waste removal and sewage systems. In America, the lowest scoring city was Atlanta, which was ranked 76th. Athens was the lowest scoring city in Western Europe, ranking 120th because of its air pollution. London was ranked 59th. Question: Among the following cities, which is the lowest scoring one? - Atlanta. - Athens. - London. - Helsinki.
Athens.

Q: Read the following article and select the best answer. Article: Food prices have risen sharply over the past few years. The good news is that the rate of increase has slowed. The bad news is that prices will not go down anytime soon. Also,the rate of global agricultural production is slowing. Yet it needs to increase 60% over the next 40 years to feed a growing world population. These are among the findings from the OECDFAO(the Organization for Economic Cooperation and Development & the Food and Agriculture Organization)Agricultural Outlook 2012-2021. FAO DirectorGeneral Jose Graziano da Silva spoke at a news conference in Rome when the report was released. Mr.Da Silva said that,not surprisingly,the world's poorest people will feel the greatest effects of higher prices. "For the millions and millions of extremely poor people, the effects of high food prices are clear--they might have to change their diets,usually to ones with poorer nutrition quality, "he said. In middleincome countries, people are gaining weight as they eat fewer fruits and vegetables and more of the cheaper but less nutritious foods. The report also shows that farmers in poorer countries will be leading efforts to feed an expected 9,000,000,000 people by 2050.The outlook predicts that farmers in Latin America,the Caribbean and subSaharan Africa will drive agricultural production in the future. Angel Gurria,SecretaryGeneral of the OECD,said:"We can feed 9,000,000,000 people by 2050 on this planet. But we have to organize ourselves better." But there are plenty of challenges.Onefourth of all agricultural land is damaged. Many countries face water shortages .And experts believe climate change is driving increasingly unusual weather patterns. The report says farmers need to use more growing methods that can't cause damage to the environment.At the same time,it says governments should end economically harmful supports and spend more money to increase agricultural production.Mr.Gurria says rich and poor nations need to treat agriculture more like a business. "In many cases,agriculture is related in people's... Question: Which of the following might Angel Gurria agree with? - Agriculture means difficulty and sadness. - Food prices will go down in the near future. - It's almost impossible to feed 9,000,000,000 people by 2050. - Both rich and poor countries should take agriculture seriously.
A: Both rich and poor countries should take agriculture seriously.

Q: Read the following article and select the best answer. Article: What are the biggest problems that society will have to deal with in the new age? There are diseases like AIDS and cancer. There's climate change, of course. And what about producing enough cheap food and energy for the world's growing population? Who's going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes, businesses will need to create the economic wealth to pay for some of these things. But who's going to make a much greater difference to something like AIDS or climate change? It's going to be a scientist. It is the scientist who can turn some new bit of science into a new technology to solve these problems. If you like thinking about the world around you, why not become a scientist? It doesn't mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do all kinds of amazing things that are actually interesting! Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow's scientists. Don't think a scientist is far away! Maybe you like cooking? You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order to improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world. Looking for something to do for the rest of your life? My advice? Take a long and hard look at science. It is interesting and ever. Question: Most people think the life of scientists is _ . - amazing - boring - colorful - unreal
A: boring
