Inspired by a 9-year-old cyclist who uses only part of one hand, a group of University of Guelph students has won an international award for their invention--a bike brake lever . It pulls both the front brake and the back brake at the same time. Lauren Turner was able to ride her bike, but not as confidently and quickly as her friends. "She couldn't use the front brake. She was only using the back brake, but the front brake makes you stop twice as fast," says Micha Wallace, who with Katie Bell, Anina Sakaguchi and Andrew Morris won second prize in the James Dyson Awards for their single-handed bike braking lever. "She used it all last summer and she had no problems. She said it helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace. The invention was the fourth-year design project for the four students. They designed, tested and created a prototype within a four-month period. When Wallace heard about the James Dyson Awards on the news, she and her co-inventors entered their project in the UK-based contest. The contest mainly rewards student designers who create products that improve the way we live. The Guelph students collected the second prize -PS2,000 for them, plus PS500 for their school. As well, they had a chance to meet James Dyson, a UK inventor. While praising the students for their creativity, Dyson said the single-handed lever could improve safety for all cyclists. "By using both brakes at once," he explains, "you could prevent the possibility of flying over the handlebars and ending up with an injury." The students are hoping to sell the patent to a major company. It may be used in other devices that require two hands for operation. From the passage, we could infer that the brake lever_. A) has already been widely used B) also improves the bike's speed C) is only useful for disabled cyclists D) will have a wide market in the future

How would you like to learn more without having to study more?Here's how: 1.Get to bed and go to sleep.Your performance,attention,and the ability to concentrate are damaged by lack of sleep.Teenagers need nine to ten hours of sleep a night for best performance. 2.Feed your head.The brain runs badly if it doesn't get enough fuel.That means protein and complex carbs -eggs and wheat bread for breakfast,say,rather than sugary cereal and orange juice.The biggest mistake teens make is not to have breakfast or to go for sugar,which raises blood sugar levels. 3.Body exercise is brain exercise.Body exercise really improves brain performance,perhaps because it increases blood flow,or perhaps because it reduces stress and anxiety .Twenty minutes of activity a day that raises your heart rate will do great good. 4.Learn now what you want to remember for the rest of your life.Teenage brains are much better at remembering things than the brains of young children or adults.Scientists aren't sure why.Whatever the reason,the teenage years are the time to learn new languages and master other lifelong skills. 5.Learn the power of risk taking.Adults are always worried about the _ of teenage risktaking,and it's true that teenagers are more likely than adults to get themselves in trouble by drinking and driving.But the fact that the parts of the brain that drive people to try new,risky,and exciting things appear to be more developed in teenagers can be a huge advantage.Pick certain challenges-difficult sports,a hard job,mastering a performance art,traveling overseas-and the teenage brain is able to deal with them.They have this power they're given to go out and do it without fear. 6.Learn what you love.Because emotional systems develop fast in teenager brains,teenagers learn things they're interested in quickly and well.Their brains give them tools like attention on the project. It can be learned from the passage that _ . A) teenagers learn quickly when they are fond of something B) teenagers should be forbidden to drive C) scientists know why teenagers have a good memory D) teenagers need less sleep than adults

Ques: Chinese Jump Rope is a challenging game played by anyone anywhere. The simple rules test the skill and coordination of all players. RULES A jumper jumps until a jumping mistake is made. * A mistake can be made if a jumper jumps "out" instead of "in". * A mistake is also made if a jumper touches the rope incorrectly in the game. * After making a mistake, the jumper trades positions with an ender. The jumper starts from the very beginning of the game on the next turn. Every Chinese Jump Rope game begins with the rope held in basic position. ENDERS * Face each other and step inside the rope. * Place the rope around the ankles. * Step back until the rope is _ * Two parallel jumping lines, about 12 inches (30 cm) apart, are stretched between the enders. * The jumper stands outside the rope, ready to play. "IN" * Jump both feet inside the rope. "ON" Jump both feet on top of the rope. The left foot lands on the left rope;, the right foot lands on the right rope. "OUT" *Jump both feet from the middle to the outside of the rope. Feet land together on one side. "SIDE OUT" *Jump over both ropes from one side. Both feet land together on the other side of the rope. "SIDE-TO-SIDE" Jump quickly side-to-side. Both feet start "out" from one side of the ropes. *Jump side: The left foot lands outside the left rope. The right foot lands inside the rope. *Jump side again quickly: The left foot lands inside the rope. The right foot lands outside the right rope. Jumpers call the steps out loud while jumping. Calling helps the jumpers remember the "pattern" of the jumps! Practice "jumping steps" with these simple jumping games! The main purpose of the passage is to _ . A) make advertisements B) provide facts C) give some advice D) compare opinions

Ques:To son, Cecil, Just a quick note before I start in earnest. When I wrote this, you were 8, still a little boy. In 2002, I was called to active duty in the Marine Corps in the war on Terrorism . On the 11th of September 2001 when America was attacked, I knew that I would eventually have to go and I was filled with a deep sense of sadness. That night as you and Keiko were asleep, I looked at your little faces and couldn't help but fight the tears. I knew it would be hard for you because I had a similar experience. When I was a little boy aged 6, my dad, your Grandpa Cawley, was sent to Vietnam during the war there. I remember how much I missed him, too. But now unfortunately I have come to realize just how difficult it must have been for Grandpa to be away from his children for a year. Thinking about this, I wanted to put my thoughts and feelings down for you and your sister. I am so sorry that I had to leave for such a long time. There is no place I would rather be than with you and Keiko. You two are the lights of my life. I have known no greater joy than in the few years since you two were born. I hope to have many more years with you. If this doesn't happen, then know that I love you more than words can express. If for some reason I don't make it home, I will need you to take care of your little sister and your Mom. You will be the man of the Cawley family. Be good my son and God will watch over you as he has me. I will be waiting impatiently for the time when we can all be together again. We can infer that _ .
