Fire Prevention Information

    The University of Adelaide employs a full-time staff of fire prevention professionals. They inspect all campus buildings and test and maintain all sprinkler(喷水灭火装置）systems, fire alarms, and fire extinguishers (灭火器). They also provide educational programs or fire safety in the residence hall. Whenever you move to a new area, you should locate the fire alarm pull stations and the two exits nearest your room.

    Fire Alarms

    The floors of all campus buildings are equipped with manual(手动的）fire alarm systems which include fire alarm pull stations and pipes. Most are also equipped with automatic fire alarm systems consisting of heat detectors, smoke detectors and sprinklers. For your safety, never tamper with(胡乱摆弄）these systems. False fire alarms are illegal and may lead to imprisonment.

    Fire Drills

    A fire drill will be conducted in your residence hall every semester. During a fire drill, please do the following:

    Take your room key and ID, close and lock the door to your room.

    Exit immediately from the nearest emergency exit do not use a lift.

    Meet outside of your residence hall and wait for further instructions.

    Fire Extinguishers

    Fire extinguishers are located on each floor and in each apartment. Use a fire extinguisher only if you have been trained to do so. Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property. Misuse of a fire extinguisher will result in fines.

    Smoke Detector

    A smoke detector is on the ceiling in your room. Some buildings also have heat detectors on the ceilings. Do the following to ensure the safe operation of your smoke detector:

    If your smoke detector is working properly, the red light should be on. If the red light is not blinking (闪动)) contact residence hall staff immediately.

    Do not cover or block your smoke detector in any way.

    If a smoke detector sets off an alarm and there is no fire or smoke, inform your hall staff.

    When I was 17, I read a magazine article about a museum called the Mcnay, once the home of a watercolorist named Marian Mcnay. She had requested the community to tum it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, "Do you have the address? ""No, but I'll recognize it, there was a picture in the magazine."

    "Oh, stop. There it is!"

    The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us. "May I help you?" a man asked. "No," I said. "We're fine." Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? Sally had gone upstairs. The people in the hall seemed very nosy(爱窥探的), keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. "Where do you think you are?" he asked. I turned sharply. "The McNay Art Museum!" He smiled, shaking his head. "Sorry, the Mcnay is on New Braunfels Street." "What's this place?" I asked, still confused. "Well, it's our home." My heart jolted(震颤). I raced to the staircase and called out, "Sally! Come down immediately! "

    "There's some really good stuff( 艺术作品） up there." She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, "Sorry, please forgive us, you have a really nice place." Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.

    The real Mcnay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.

    Thirty years later, a woman approached me in a public place. "Excuse me, did you ever enter a residence, long ago, thinking it was the Mcnay Museum?"

    "Yes. But how do you know? We never told anyone."

    "That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you."

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性）

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids  (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams.Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses.

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products.   Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

     As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A. Eat your greens.

B. Always follow the doctor's advice for appropriate wear.

C. Parents usually don't care about their own eyesight.

D. Stay in good shape by taking more vitamins.

E. They can properly protect your eyes.

F. Eye care should begin early in life.

G. This frequent eye activity increases the risk for eye tiredness.

    No one is born a winner. People make themselves into winners by their own1. I learned this lesson from a(n)2 many years ago. I took the head3 job at a school in Baxley, Georgia. It was a small school with a weak football program.

It was a tradition for the school's old team to play against the 4team at the end of spring practice. The old team had no coach, and they didn't even practice to 5the game. Being the coach of the new team, I was excited because I knew we were going to win, but to my disappointment we were defeated. I couldn't6I had got into such a situation. Thinking hard about it, I came to7that my team might not be the number one team in Georgia, but they were 8 me. I had to change my9 about their ability and potential.

    I started doing anything I could to help them build a little10 . Most important, I began to treat them like11. That summer, when the other teams enjoyed their 12, we met every day and 13passing and kicking the football.

    Six months after suffering our14on the spring practice field, we won our first game and our second, and continued to 15. Finally, we faced the number one team in the state. I felt that it would be a 16  for us even if we lost the game. But that wasn't what happened. My boys beat the best team in Georgia, giving me one of the greatest17of my life!

    From the experience I learnt a lot about how the attitude of the leader can18the members of a team. Instead of seeing my boys as losers, I pushed and 19them. I helped them to see themselves20, and they built themselves into winners.

    Winners are made, but born.

    Lucy looks like any other schoolgirl, fresh-faced and full of life. Lucy is looking forward to challenge of her new A-level course .But unlike school friends ,16-year-old Lucy is not spending half-term (rest)Instead, she is earning $6500 a day as model in New York.

    Lucy   (tell) that she could be Britain's new supermodel earning a million dollars in the new year. Her father Peter44,wants her to give up school to model fulltime But Lucy,  has taken part in shows along with top models wants (prove) that she has brains as well as    beauty she is determined to carry on with her  (educate).

    She has turned down several   (invitation) to star at shows in order to concentrate    her studies. After school she plans to take a year off to model full time before going to university to get a degree in engineering or architecture.

    Lucy says, "My dad thinks I should take the offer now. But at the moment, school comes first. I don't want to get too   (absorb) in modeling. It is   (certain) fun but the lifestyle is a little unreal. I don't want to have nothing else to fall back on when I can't model my more."

Dear David,

    I've learned it from the Internet that you want to make a Chinese friend. In order to knew a foreign language thoroughly, four things are necessary. Firstly, we must understand the language when we hear it speak. Secondly, we must be able to speak it correct with confidence and without hesitation. Thirdly, we must be able to read the language, and fourthly, we must be able to write it. We must be able to make sentence that are grammatically correct.

    There is no easy way on success in language learning. The good memory is of great help, but it is not enough only to memorize rules from a grammar book. It is not much use learning by heart long list of words and its meaning, studying the dictionary and so on. We must learn by using the language. If we are satisfying with only a few rules we have memorized, we are not really learning the language. "Learn through use" is a good piece of advice for those whom are studying a new language. Practice is important. We must practise speaking and write the language whenever we can.

你怎样得知David的愿望的；

你愿意成为他的朋友；

你打算如何帮助他；

你盼望他的回复。

注意：1）电子邮件的格式已为你写好，不计入总词数；

2）词数120左右。

……

    Yours sincerely, Li Hua
