A few months ago, while driving home from work, I stopped at a gas station to gas up my car before heading home. When I went in to pre-pay for my gas, I saw a man with his son ahead of me in the line. They were a little dirty from working & painting at a local job site and the man asked the clerk to help them patiently. The clerk behind the counter seemed annoyed and not interested in talking to them. From their conversation, I knew that the man had lost his wallet, was almost out of gas and still had 1.5 hours drive to get himself and his son home. He couldn't write the clerk a check. Because he knew the money in his account wasn't available yet. The clerk asked them to move aside and let me up to the register. I gave the clerk two 20 dollar bills and told him to put $20 on my pump and to pre-pay $20 on their pump also. When I went back out to fill my gas tank, the teenage son came towards me to express his appreciation. His father was too excited, so he stayed inside the store until I was gone. They asked if I would accept a check from them for the money, but I refused. I told the teenager to "pay it forward" and help _ The man's problem was that _ . A) he had to drive for another 1.5 hours B) he couldn't reach his job site in time C) he had lost his checkbook by mistake D) he had no money to pay for the gas he needed

A blocked airway can kill someone in three to four minutes, but it can take more than eight minutes for an ambulance to arrive. So a simple procedure such as opening someone's airway can save their life while they're waiting for emergency medical help. This means you're more likely to give first aid to someone you know than a stranger. There are many misconceptions surrounding first aid. Below are the 'most popular' ones with details of what you should do. You should put butter or cream on a burn. The only thing you should put on a burn is cold water - keep the butter for cooking. Put the affected area under cold running water for at least ten minutes. The best way to treat bleeding is to put the wound under a tap. If you put a bleeding wound under a tap you wash away the body's clotting agents and make it bleed more. Instead put pressure on the wound with whatever is available to stop or slow down the flow of blood. As soon as possible call 999. Keep pressure on the wound until help arrives. Nosebleeds are best treated by putting the head back. If you put the head back during a nosebleed, all the blood goes down the back of the airway. Instead advise them to tilt their head forwards and ask the person to pinch the end of their nose and breathe through their mouth. You need lots of training to do first aid. You don't - what you mostly need is common sense. You can learn enough first aid in a few minutes to save someone's life - whether it's from a book, attending a course or watching videos online. Remember: anyone can save a life If a bleeding wound is put under a tap, what should happen? A) It will help the bleeding stop at once. B) It will help produce more clotting agents. C) It will produce more pressure on the wound D) It will bleed more and hard to stop

Q: "It's this time of year when the weather starts warming up and frogs start breeding - but they haven't been breeding," says John Wilkinson, research and monitoring officer at the Amphibian and Reptile Conservation Trust (ARC). Amphibians are just one of the groups of animals that nature observers fear may have problems reproducing this year, as groundwater levels are even lower now than in the infamously dry summer of 1976, according to the Department for Environment, Food and Rural Affairs (Defra). According to the UK's Centre for Hydrology and Ecology the average rainfall so far this winter has been the lowest since 1972. "If ponds dry up totally," says Mr. Wilkinson, "you could have lots of dead tadpoles." Drier and windier conditions could also make it more difficult for juvenile amphibians to survive their journeys between wet habitats. But Peter Brotherton, the biodiversity manager for Natural England, says that "drought is part of nature's cycle", and, at present, a lot of animals, plants and insects are still in hibernation. This means that the population picture is unclear. "However, when we get extreme events, we get animals dying," he says. "And what is worrying is that normally at this time of year we expect soil to be near saturation after winter." Charlie Kitchin, the RSPB's site manager of the Nene Washes in Cambridgeshire, says the 2,000-acre wetland and grassland area is now struggling following two winters with relatively little winter rain and no flooding. One species that could suffer, he says, is the black-tailed godwit . "There are only 50 breeding pairs in the country, and we have 40 of them, and everything is bone-dry," Mr Kitchin says. But one bad nesting season, he says, is "not the end of the world". "One of the features of flood plains is that they're _ anyway," he adds. "But if they fail to breed another year, the population is likely to dip again." What really worries Peter Brotherton is that _ . A) drought is part of nature's cycle B) animals are still in hibernation C) soil at this time is far from saturation D) the population of animals is still unclear
A: C

Milk was one of the main foods of people long before history was written. It will probably keep on being one as long as there are animals that give milk. Even the word "milk" is very old. It comes from Sanskrit ( ), one of the oldest languages known to man. A very old picture of _ has been found. It was drawn more than five thousand years ago. In the years long ago, people got their milk from their own animals. But later new inventions made the milk industry a big business. In 1851 Gail Borden found a way to take some of the water out of milk. This made it keep much longer. Four years later, Louis Pasteur introduced a way to kill the bacteria ( ) in milk. Next, a special milk bottle was made. This was followed by the invention of machines that could fill bottles with milk. These discoveries had a great effect on the milk industry. They meant that milk could be stored longer. Some people believe that milk drinking will become less popular that it has been. But remember how long milk has been an important food and think of many ways in which it is useful. It seems safe to say that milk industry will always be important. Milk is the most possibly to be a food of ours _ . A) as long as there are animals that can give milk. B) where there are animals that can give milk. C) if there are animals and people in the world. D) if we want to eat every day.
