20．The central government gave many pprivileges to Chongqing in all aspects．——青夏教育精英家教网—

17．Six months ago，Xie Lei boarded a plane for London．She was nervous when waiting in a queue at the airport．It was the first time that she （61）had left （leave） her motherland．She went to a university to study for a business qualification．She was halfway through the preparation year，which most foreign students complete before （62）applying （apply） for a degree course．She（63）highly（high） recommended it．"The preparation year is most （64）beneficial（benefit），"she said．The preparation year helped her adjust to the academic （65）requirements（require） of a Western university．A new way of life took up all her concentration in the beginning．（66）To participate （participate） in social activities，Xie Lei lived with a host family who gave her lots of good advice．"Also，when I miss my family，it's （67）agreat comfort to have a substitute family．"More importantly，she had more confidence．（68）Occupied（occupy） with her studies，she couldn't have a balance between study and a social life．Xie Lei told me that she feels much more at home in England now，and （69）what had seemed very strange before now appears quite normal．All （70）inall，I wish Xie Lei all the best in her new enterprise．

16．Years ago we said that LEDs would be something in the future．But as time goes on，LEDs have become the present because of rapidly falling prices and improving quality．We've firmly entered the LED period，as Lloyd showed with his experience of changing 100% of his lights to LEDs．
The physics Nobel Prize in 2014was given to three well-known Japanese scientists-Isamu Akasaki，Hiroshi Amano，and Shuji Nakamura-who invented the blue LED and made LEDs truly reach their potential as a mass-market light source．
As we can know，LEDs take the lead in the competition when it comes to efficiency（效率）．Most LED lights that you can buy right now can't reach the 300watt shown here，but this is what we know it can be achieved，and over the coming years we should gradually move closer to that goal．
Why was blue so important？Because without it，we couldn't make high-quality white light from LEDs．Red and green LEDs have been around for a long time but blue was really missing．Thanks to the blue LED we now can get white light sources which have very high energy efficiency and very long lifetime．
With good use of LEDs，the world's electricity used for lighting can be reduced greatly．But energy-efficiency isn't the only thing．Material efficiency is also very important for LEDs．A LED can last up to 100，000hours，compared to 10，000hours for fluorescent（荧光）lights and 1，000for incandescent bulbs （白炽灯泡）．This means that only a small part of the bulbs need to be produced over time．That can greatly reduce the costs．Using LEDs，the quality of light is also improved，so that people can better see when they're out at night．

15．Energy is a balance between food and physical activity．The energy from the food we eat is influenced by the amount and type of food we choose．The energy we give out is determined by how physically active we are．Overweight is a result of imbalance between the energy we are eating and the energy we are giving out．In NSW one third of adults are now considered to be overweight．
Physical activity guidelines can help us balance our energy．Being physically active does not mean that you have to be training to be an athlete．It is exercising at a moderate level for 40-60minutes on most days．By moderate，we mean at a level that you can still talk to someone while exercising，but not easily．
One key to improving our fitness is to see activity as an opportunity，rather than an inconvenience．Often it is the little changes through the day that can add up to improve our health．Some suggestions might be：
※spend some time gardening
※play outdoors with the kids
※take the dog around the block
※park your car a little further away
※avoid driving to the local shop
Sometimes planning our time also helps us to stay more active．It is often easy to use the excuse that we are too busy to find the time to exercise．We do not need to do the activity all at one time．Make use of the 10minutes after lunch，the 5minutes while the children are not arguing，or the 3minutes while the dinner is cooking!It may help to draw up a weekly schedule of your family's activities to find time where you can do physically active things together．

14．To celebrate the end of our exams，my friends and I went to a fast food restaurant．We ordered hamburgers and Coca Cola at the counter．When our food came，I started walking towards an empty table．By bad luck，my purse strap （带子） got caught on a chair and the tray （托盘） that I was holding slipped from my hands and went flying in the air．The tray，and its contents，fell on a man who was just about to take a bite of his sandwich．I stared，greatly shocked，as the drinks soaked （浸湿） his white shirt．
Then I closed my eyes and prepared myself for his burst of anger．Instead，he said"It's OK"to comfort me before he disappeared into washroom．
Still shaky and unsure what to do next，my friends and I went to a table and sat there，trying our best to look calm．A moment later，the man came out of the washroom and approached our table．My heart almost stopped beating．I thought he was going to ask for my father's number and call him．
To my surprise，he merely smiled at us，handed us some cash and said，"Buy yourself new hamburgers．"He then walked away without even finishing his food．
He could have made what was already an uncomfortable situation worse，but he chose a different way and gave us a reason to believe that there is still kindness in this world．I'll never
forget his actions．
