In-line skating is a fun sport that everyone can enjoy. Follow these safety tips to keep skating safe and fun. Step 1: Gear up! Even before you put on your skates, put on all your safety gear . Step 2: Buckle up! Strap on your skates. Make sure they fit well and are snugly around your ankles. This helps your ankles stay strong and straight. Step 3: Fall down! You probably do not usually try to fall. But it is good to practice falling on skates. Fall forward onto your knee pads. Put out your hands and let your wrist guards hit the ground. See? Are you surprised that it doesn't hurt? Practice falling until it is easy to fall forward and get up again. If you are not afraid to fall, you will try new things. Knowing how to fall will help you be a better skater and find your balance. When you can stay balanced, you won't fall as much. Step 4: Stop! Make sure you can stop on your skates. The quickest and safest is probably the brake stop. The brake is usually on the back of the right skate. The brake stop: Roll forward with your skates pointing the same way. Let your right skate roll a little forward. Bend your knees as if you are sitting down. Then press your right heel down hard. This will make your brake pad drag on the ground until you stop. The T stop: Roll forward with your skates pointing the same way. Then turn your right foot out so the toes are pointing to your right. Drag your right skate. Let the wheels drag on the ground until you come to a stop. Another way to stop is to run or jump onto the grass. Step 5: Roll around! Find a flat, smooth place to practice. Do not skate in streets. Parks and playgrounds are good places to practice. Look for "No skating" signs to make sure you can skate there. How is the passage organized? A) It tells stories about skating. B) It gives descriptions of skates. C) It uses a question-and-answer form. D) It gives step-by-step instructions.

Ques: Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded  commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet's power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks. Companies are trying to offer an alternative, clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids . The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030. When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps. Which of the following statements is NOT true according to the passage? A) Lifton's Medis Technologies is tapping into fuel cells and solar panels. B) The fuel cell has been around for about 150 years. C) The fuel cell's commercial development did not begin until the 1960s. D) When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.
Ans: D


It's great fun to explore   new places--it feels like an adventure, even when you know you're not the first to have been there. But make sure not to get lost or waste time going round in circles. * Do the map reading if you're being driven somewhere. It'll be easier if you keep turning the map so it follows the direction you' re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat. * Get a group of friends together and go exploring. You'll need a good map, a compass  , a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies  . Tell someone where you're going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up. * See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc. ) in the fastest time, or simply as a spare-time activity. Either way, it's not only good fun, but a great way to keep fit. Orienteering activities can   _  . A) make people work fast B) help people stay healthy C) help people organize other activities D) make people get prepared for sports
