Revealed to the world by the famous British explorer, Dr David Livingstone, in 1855, the Victoria Falls are one of Africa's best-known natural wonders. They form a natural border between Zimbabwe and Zambia . The falls are named after Queen Victoria by Livingstone. They were known to the native people in the 18th century as: "the smoke that thunders". The waterfall is formed as the two-kilometer-wide Zambezi River spills over the edge of its giant stone riverbed and falls into the gorge below. At their highest point, the Victoria Falls drop a distance of 108m, almost twice as far as the Niagara Falls. As much as 546 million cubic meters of water per minute falls over the edge from that height. Viewing the falls from the Zambian side means that visitors can follow a path that goes right up to the falls. The falls can also be viewed from the Boiling Pot, right in the depths of the gorge at the bottom of the falls. The 111-meter-high Victoria Falls Bridge, a railway crossing, is now a popular place for Bungee jumping. It can be crossed on foot for excellent views of the falls and the winding blue-green waters of the Zambezi River. It is also possible to see the falls from a plane. The area around the falls is a major game-viewing place. The best time to view the Victoria Falls is between December and July, when the water level is the highest.

Mr. Baker was happy. One day Mr. Baker went to watch his wheat. To his surprise, a lot of crops were eaten up by a horse. He became angry but could not find out whose horse had eaten them.

Q: Health experts have long worried about the increasing rate of obesity in kids. It's an important concern: Being weight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts when you were a baby and the chance that you would become overweight? Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts. You probably think of bacteria only as germs that can make you sick. While it's true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These "good" bacteria live in your guts, where they process the food you eat. Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby's body. Growing babies get additional "good" bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later. So how could these bacteria affect weight? The researchers still haven't tested that question, but future tests might lead to an answer. The purpose of writing this passage is to _ . A) introduce the role of bacteria in children's weight B) analyze the influence of obesity on kids C) give advice on how to lose weight quickly D) explain the function of bacteria in foods

I was in my first year of college, making friends and enjoying life, but then my whole world turned upside down. I had a heart attack. It felt like someone was stabbing me in the chest with a knife over and over again. After three months of rest I went back to college, but then things took a turn for the worse. I was staying at my Nana's house and woke up in the middle of the night with a terrible pain in my chest. I knew I was having a heart attack again. I couldn't even shout for help. Luckily my grandpa was going to the toilet and heard me falling out of bed. If it wasn't for him, I probably wouldn't be here. The two holes in my heart were causing the problems and I needed an operation immediately to repair them. Unfortunately, the surgery didn't go well and they only managed to repair one of the holes. When I woke up from the operation, I had a really dry mouth and couldn't wait to have something to eat and drink. The biggest shock of all came when I was told that I needed a heart transplant and was put on the register. The doctors were stunned at how quickly heart failure came on - it usually takes years, but it took my heart less than six months to get to that stage. My whole world came crashing down, but I stayed strong. It was a choice between crying every day and getting on with my life. As time went on, life became even harder. I hated feeling weak all the time and needing help with everything. It got to the point where I thought I would never get a new heart. I was diagnosed with depression. Even though I thought that Christmas 2008 would be my last, I really enjoyed it and even had a good New Year. Everyone was crying for me when the clock struck midnight and they told me to keep fighting. A week later, I got a call from the doctors saying they'd found a suitable donor . My wish came true and thankfully the operation went well. I spent four hours in surgery where they took out my old heart and put a new one in. When I woke up I burst out crying. I had a second chance at life. Which one would be the best title for the text? A) Choices matter B) Rebuilding my world C) Waiting for a new heart D) The most special Christmas
