Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste. and transport. But things had to be different in London because seven years ago it bid for the Olympics through the concept of “a One Planet Olympics”.
What is most impressive is that London used the construction of the Olympic Park as an opportunity to clean up polluted areas — 2 million tons of contaminated (被污染的) soil were removed and 200 old factory buildings, were torn down, according to sustainablebusiness.com. But that’s not all —. 99 percent of the debris (废瓦砾) were reused to build the Olympic Park. For example, part of the Olympic Stadium’s roof is made from 2,500 tons of steel tubes recycled from old gas pipelines.
As well as using recycled materials, all venues were built with green building techniques. The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed. Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent, according to sustainablebusiness.com.
The effort that London made to deal with waste also deserves praise. Water used for drinking and watering plants was from collected rainwater or recycled wastewater. In this way. about 30-40 percent less water was used in total. Waste food packages were either recycled or processed and turned into renewable energy.
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport. For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions.
The clean anti-doping (反兴奋剂) result also added to the greenness of the Games. The International Olympics Committee (IOC) said that the devices used this time were the most accurate and advanced. Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games.

Living in an exciting social environment was found to reduce fat in mice"s belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body"s nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team"s findings appear in the journal Cell Metabolism, said, "I"m still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It"s not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death; it"s equal to cigarette smoking to a certain extent. Social activities are very vital.
小题1:What information can we get from the first two paragraphs?
| A．Brown fat stores calories and makes us fatter |
| B．It doesn"t take long to turn white fat into brown. |
| C．Social excitement helps gain more weight |
| D．Brown fat can burn energy to produce heat. |
| A．Levels of brown fat can be increased by socializing. |
| B．The mice lacking social life lose more weight. |
| C．The research findings haven"t been published so far. |
| D．Dr Matthew During wasn"t convinced of the result. |
| A．the fat in mice"s belly was reduced because of the relaxing environment |
| B．a sedentary lifestyle and high calories foods influence people"s social life |
| C．surfing the Internet may influence people"s face-to-face communication |
| D．cancer and death are mainly caused for lack of social life |
| A．Brown fat is beneficial to people"s health. |
| B．Socializing is unnecessarily important in people"s daily life. |
| C．White fat can be changed into brown fat. |
| D．Socializing contributes to people"s losing weight. |
In 1997, Avian Influenza caused widespread panic in Hong Kong．It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people"s anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong．
Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed．In many people"s minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak．
These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people"s confidence in food safety can be destroyed instantly—even in a developed country
小题1:Which of the following is true according to the passage?
| A．Nowadays, food safety incidents spread inside one country |
| B．In 1997, Avian Influenza caused great fear in Hong Kong |
| C．16 Germans died of deadly E. coli after eating cucumbers |
| D．Food safety is only related to the developing countries |
| A．serious | B．common | C．urgent | D．unique |
| A．food safety problems spread from one country to another |
| B．the staff of a Shenzhen chicken farm caught Avian Influenza |
| C．the strictest standards protected European people from getting E. coli |
| D．China is a country where food safety problem is related to people"s age |
| A．Food Safety Problem Is a Global Issue |
| B．Cucumbers Are Popular in European Countries |
| C．Avian Influenza Originated from Shenzhen |
| D．Food Safety Issues Are Various from Country to Country |
Other doctors have warned about “iPad Hand,” a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain.
In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic(人体工学的) principles:
Avoid awkward positioning. Don’t strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren’t leaning over for a long period of time.
Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes.
When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle.
Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you’ll be resting both hands on the keyboard. And since you won’t be holding the tablet, you’ll be less likely to experience hand or arm pain.
小题1:What kind of product for hand-held devices does the writer discuss?
| A．One for recording. | B．One for charging. |
| C．One for telephoning. | D．One for typing. |
| A．cashed | B．created | C．changed | D．completed |
| A．If you are holding an iPad for long periods, it could cause spinal damage. |
| B．Text Neck symptoms include long-term damage in the back. |
| C．You are advised to lean over in relation to the device. |
| D．You should rest your hands on the keyboard at times. |
| A．Personal Finance | B．Science Fiction Monthly |
| C．Mind and Body | D．Smartphone World |
The Green Microgym in Portland，Oregon has all the usual stuff you"d expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren"t the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕获）the energy you create while riding, converts（转换）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流电流）into any standard wall outlet-for this reason，the product line"s name is Plug Out-and the energy created is used before the building draws power from the grid（电网）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．
小题1:Members of the Green Microgym earn gift certificates for_______．
| A．using the man-powered exercise equipment |
| B．saving electricity for local businesses |
| C．producing green electricity to power their phones |
| D．paying higher membership fees |
| A．they are easier to ride |
| B．they are more expensive |
| C．they don"t have wires connected |
| D．they can not store extra electricity |
| A．People"s unwillingness to go green． |
| B．The high cost of making it. |
| C．Safety problems concerning electricity. |
| D．Lack of certificates． |
| A．change to a different gym |
| B．use green exercise equipment |
| C．switch on the spin bikes |
| D．add a battery to the machine |
Digestion 5 a complex series of signals between the gut (肠道)and the nervous system and it takes about 20 minutes for the brain to tell that the body has eaten enough. This means that if someone eats too 6 , the signals will come slowly, leading to 7 .
Scientists say that distractions make it 8 for us to remember what we have eaten. This absent-mindedness stops us from feeling 9 – and sends us reaching for some snacks later on. It is thought that our memory of what we have eaten plays a key role in 10 appetite. This means that distractions stop us from remembering the detail of what we have eaten – leaving us feeling 11 .
Advocates of mindful eating 12 chewing food slowly and taking note of its color, smell and flavor. Before 13 dieters should ask themselves if they are really hungry---and if not, distract themselves by going for a walk or reading. Done 14 , mindful eating may not only leave you 15 , but also make you enjoy mealtimes.
