冲刺100分单元优化练考卷系列答案I’m a 20-year-old boy, and the following is my story．
A month after I graduated from high school in August，2007，I was coming home from swim practice in the training centre of the city and was involved in a car accident. I was so seriously injured that I was in a coma for more than two months at Prince Georges Hospital．
I suffered a lot from the experience of dying eight times during my coma and I couldn’t open my mouth to talk or to communicate when I eventually came around．At that time，it seemed that walking was never going to happen again due to all the extreme injuries. Just like my body，my dreams were completely destroyed. But I was not going to let my injuries stop me from realizing my dreams．
After receiving a total of 15 operations and 36 blood transfusions, I had to make every great effort to learn to talk，eat，walk，shower，and live on my own again．When I was out of hospital，I still had to go to outpatient therapy in Waldorf, Maryland．After I spent a few months in a wheelchair, I took baby steps to walk on my own．It was a miracle that I was able to walk again, but I still wanted to prove that I could not only walk, but also run. When it came true, I wanted to get back into the pool again．After having a few lung tests，I was able to go in the pool a little bit each week．After a few months of swim training，I began my freshman year at Mary’s College of Maryland and then became a proud member of the swim team．
By telling my story, I want to make a positive influence on the world．I am just trying to 1ive every day to the fullest and inspire other people never to give up their dreams no matter how bad a situation is to them. I remember when I was still in my hospital bed，I would have my mom and dad push me round in my wheelchair to the other rooms to see the other patients and chat with them and their family members．I wanted to let them know that everything was going to be okay.

Betty Skelton was often called “The First Lady of Firsts’’ because of the many records she set. She grew up in Pensacola, Florida, watching airplanes flying to and from a nearby navy base. As a child, she persuaded her parents to let her take flying lessons. By 12, Betty made her first flight alone, though not legally permitted to do so until she turned 16.
During the 1940s, female pilots were mostly prevented from commercial and military flying. So Betty Skelton decided to use her flight skills in aerobatics(特技飞行)，performing difficult turns, drops, and other exercises. She began performing and competing around the country.
She won the International Feminine Aerobatic Championship(IFAC)for three years in a row, starting in 1948. She and her little Pitts Special plane the “Little Stinker’’ became famous.
Dorothy Cochrane is an aviation expert who once studied and worked with Betty Skelton. “Betty was such a wonderful aerobatic pilot that she really set the bar high for other women to follow and she was a great role model for them. She really was as good as some of the men.”
Once Ms. Skelton had made her mark on flying, she moved on to racecars, becoming the first female test driver in the racecar industry. She set several land speed records. She also set a cross-country record, driving from New York to California in under 57 hours. And she became one of the top women advertising experts working with General Motors in support of the company’s Corvette car.
Ms. Skelton died in August, 2011, at the age of 85. Visitors to the Washington area can see her “little Stinker” plane at the National Air and Space Museum’s Steven F. Udvar-Hazy Center in Chantilly, Virginia. The small red and white plane hangs high in the air above the entrance to the museum.

Once upon a time there was a precious sword. Now, this sword belonged to a great King, and for as long as anyone could remember, the King spent all his time in his place, enjoying its shows and competitions with other swords. One day a great dispute（争端）arouse between this King and the King of a neighbouring country. It ended with both declaring war.
The sword was greatly excited at the prospect of taking part in its first real battle. It would show everyone how truly brave and special it was, and would become well-known throughout the kingdom. On the way to the front line, the sword imagined itself the winner of many battles. However, when it arrived, the first battle had already broken out, and the sword got to see the results of the war. What it saw had nothing in common with what the sword had imagined. No elegant shining knights, successful, with their weapons shining in the sunlight. Instead, all the sword saw was broken weapons, and a large crowd of hungry and thirsty men. There was hardly any food left. Everything was covered in dirt and disgusting smell. Many were half dead and scattered on the ground, bleeding from multiple wounds.
Seeing this, the sword realized it liked neither wars nor battles. It decided it preferred to live in peace and spend its time taking part in tournaments and competitions. So, on the night before what was going to be the big final battle, the sword tried to find a way to prevent it from taking place. After a while, the sword started to vibrate（颤抖）. First it gave out a low buzz, and then this gradually got louder, until it became an annoying metallic noise. The swords and armour（盔甲）of the soldiers asked the King’s sword what it was doing. It told them, “I don’t want there to be a battle tomorrow. I don’t like war.”
One answered, “No one likes it, but what can we do?”
“Make yourself vibrate, just like what I’m doing,” said the King’s sword. “If we make enough noise, no one will sleep.”
So the weapons started vibrating, and the noise became deafening. It was so loud that it reached the enemy camp, and the weapons there, which were equally sick of war, joined the protest.
The next morning, when the battle should have begun, not a single soldier was ready to fight. No one had managed to get even a wink of sleep, not even the King or the Generals. So they spent the whole day catching up on sleep. During the evening they started to wake up, and decided to put off the battle until the next day.
However, the weapons, led by the King’s sword, spent the night repeating their peace song, and again no soldier could rest. The battle had to be postponed yet again, and this carried on for the next seven days. On the evening of the seventh day, the Kings of the two armies met to see what they could do about the situation. Both were very angry at their previous disputes, but after being together for a while they started to discuss their sleepless nights, the surprise on their soldiers’ faces, the confusion between day and night, and the amusing situations all this had created. It wasn’t long before both were laughing, like friends, at these little stories. Fortunately, they forgot their old disputes and they put an end to the war, each returning to their own land with the double joy.

Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（症状）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提钻）on a building site.
Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（听觉神经）that connect to the brain. If this happens, hearing loss becomes permanent.
【小题1】Which of the following shows that you are suffering hearing loss?
| A．You are interested to listen to others’ talking. |
| B．You have to read others’ expressions to understand them. |
| C．You can only understand others over the phone. |
| D．You always think you hear the ringing of the phone. |
| A．Listen at least an hour every time. |
| B．Turn up the volume to the highest level. |
| C．keep the sound lower than 60% of its highest volume. |
| D．Choose classical, rock or heavy metal music. |
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.
| A．d-a-c-b-e | B．e-c-a-b-d | C．b-c-a-d-e | D．d-e-a-c-b |
| A．music that teenagers like | B．hearing problems caused by the loud world |
| C．ways that teenagers enjoy music | D．dangerous modern lifestyles of teenagers. |
