2．A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2，500 pounds．
The machine squirts （噴射） out chocolate and，via computer instructions，allows the user to build any shape they like out of the food．But makers Choc Edge have missed the Easter rush．Even so，they hope the printer will be snapped up by retailers （零售商） immediately they come to the market．Britain's biggest chocolatiers Thornton's have already said they are interested．Because of the high cost，however，few individuals are likely to buy one．But the device could one day allow people to design their own 3D objects after submitting their designs on a website．Dr Hao，founder of Choc Edge came up with a prototype （原型） last year and has only just perfected it so that it can now go on sale．"We've improved and simplified the machine，so now it is really easy to use，"he told the BBC．"You just need to melt some chocolate，fill a syringe （注射器） that is stored in the printer，and get creative printing of your chocolate．"
3D printing is a technology where a three dimensional object is created by building up successive layers of material．The technology is already used in industry to produce plastic and metal products，but this is the first time the principles have been applied to chocolate．The research has presented many challenges．Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles．Dr Hao said，"What makes this technology special is that users will be able to design and make their own products．From reproducing the shape of a child's favourite toy to a friend's face，the possibilities are endless．It could be developed to help consumers design many products from different materials，but we've started with chocolate as it is easily available，low cost and harmless．""There is also no wastage as any spoilage （損壞物） can be eaten．"Dr Hao added，"Eventually we may see many mass-produced products replaced by unique designs created by the customer．"
EPSRC chief executive Professor Dave Delpy said，"This is a good example of how creative research can be applied to create new manufacturing and retail ideas．By combining developments in engineering with the commercial potential of the digital economy We can see the new market prospect （前景）-creating new jobs and，in this case，the chocolate printer is called sweet business opportunities．"
67．Which is the advantage of the chocolate printer？C
A．It is easily available，low cost and harmless．
B．It mainly produces children's favourite toys．
C．The user can build the shape they like via computer instructions．
D．The designs made by it are the same as many mass-produced products．
68．What can we conclude from the passage？B

C．The printer was perfected and went on sale many years ago．
D．It's the first time that the technology has been used in industry．

68．B．推理判斷題．結(jié)合最后一段的，We can see the new market prospect （前景）-creating new jobs and，in this case，the chocolate printer is called sweet business opportunities，我們可以看到新的市場前景（前景）-創(chuàng)造新的就業(yè)機會，在這種情況下，巧克力打印機被稱為"甜蜜的商機；故選B．
69．B．推理判斷題．結(jié)合最后一段Dave Delpy所說的話"By combining developments in engineering with the commercial potential of the digital economy We can see the new market prospect （前景）-creating new jobs and，"可知他對這種產(chǎn)品是支持的．故選B．
70．C．推理判斷題．通讀全文，可知本文介紹了一種新產(chǎn)品的開發(fā)和前景，可以確定這是篇新聞報道；故選C．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．

3．Pool Safety Tips for Kids
On a hot summer day，there are few things that are more appealing than a nice cool pool．（36）EAnd it is completely relaxing．Of course，if you have children，there are certain safety measures you should take，whether you have a pool in your backyard or are going to a public pool．
Go swimming together．No person should ever swim alone．Though many people do，the simple truth is that it only takes a second to become injured or drown．（37）FHaving someone there with you can make the difference between life and death．This is especially true for young children．If your child is under the age of 5，you should never allow them to swim out of arm's length．
（38）AKids love to chase one another through the water．But it is important that you emphasize to your children that at no time should they be running around the pool or pushing anyone．In the water，teach children not to jump on top of one another and to watch their surroundings，so that they do not accidentally knock into others，injuring them．Playing around in the pool is very interesting but dangerous．
Keep it locked．If you own a pool，you must have a locking gate around your pool．
（39）D Keep the gate locked at all times，even when you are physically in the pool．It is terrible for children to steal into the pool．
Know the way out．（40）BMake sure that they know where all ladders are，and that you teach them to use them for entering and exiting the pool safely．Although your child may be able to lift herself or himself out of the pool using the side，that is not the safest way to go．

A．Don't play around in the pool．
B．Be sure to show all children the proper way to exit the pool．
C．Swimming under water is forbidden in the poor．
D．This is to prevent children from entering the pool without your permission．
E．Slipping into the water seems like the perfect way to deal with the heat．
F．Something sad happens every year．
G．Make sure kids know food should be eaten either before or after swimming．

13．The air quality has worsened in the Chinese capital since Wednesday，causing renewed discontent among residents．
Without rainfall and wind to decrease pollutants，particulate matter（顆粒物質(zhì)） has been accumulating in the air．Most monitoring stations measured PM 10 （particulate matter smaller than 10 micrograms） at higher than 300 micrograms per cubic meter．In southwestern Beijing's Fangshan District，the Liangxiang station recorded 516 micrograms of PM 10 per cubic meter，the highest reading of the day，according to the Beijing Municipal Environmental Monitoring Center．More than 150 micrograms is considered harmful to health．

2．A new set of R's is here：Recycle，Reduce and Reuse．These three"Rs"，when used every day，can reduce the amount of waste going into landfills，reduce the litter polluting the land and water，conserve（節(jié)約，保存）energy and save you money．
Recycling is one of the easiest ways to save energy，money and time while reducing the amount of garbage going into landfills．
Most communities have roadside pick-up service to recycle common household items like glass，steel，aluminum，newspaper and cardboard．By separating out the recyclable items from normal household trash，you can reduce the amount of trash entering a landfill by more than 75percent．
Recycling one aluminum beverage can（飲料罐）saves enough energy to run your television for three hours．Even better，local recyclers or scrap-metal dealers may pay money for your metal recyclables．
It is estimated that the 54billion cans recycled last year in the US saved l5million barrels of oil．That is equivalent（相等的）to the US oil consumption for one day．Recycling other household items offers similar savings in money and energy．
Composting food waste will reduce your trash load even more．A basic compost pile built with the help of instructions from numerous resources on the web can be constructed over a weekend，using materials easily obtained from local hardware or home improvement stores．In addition to reducing your waste，this all-natural recycling provides safe，clean and organic fertilizer for your garden，eliminating the need to buy chemical-derived products．
Finally，recycling other household items like computers，televisions and monitors and household chemicals like pesticides（農(nóng)藥）and paints will remove dangerous chemicals like mercury（水銀）and lead from the landfills．
If your community doesn't offer recycling programs，contact your local government to get one established．

46．What's WRONG about recycling in the eyes of the author？C
A．It's energy-efficient．    B．It's money-saving．
C．It's time-consuming．      D．It's environmentally friendly．
47．RecyclingCaluminum beverage cans saves enough energy to keep your TV on for half a day．
A．six    B．five    C．four    D．three
48．What's the possible meaning of the underlined word"Composting"in the sixth paragraph？A
A．To turn waste into fertilizer．        B．To throw waste into dustbin．
C．To make waste clean and useful．       D．To find new land to put the rubbish in．
49．The following paragraph of the text may talk aboutA．
A．something about reusing    B．recycling programs
C．community activity         D．environment protection
50．The text tells us the way of living aC life．
A．happy    B．rich    C．green    D．economical．
