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(节约,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(饮料罐)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(农药)and paints will remove dangerous chemicals like mercury(水银)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.

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 (喷射) 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 (损坏物) 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
A.The printer sold well during last Easter.
B.The technology of 3D printing promises a good future.
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.
69.Dave Delpy's attitude towards the chocolate printer isB.
A.doubtful              B.approval         C.negative         D.critical
70.We can conclude that this passage is aC.
A.science fiction       B.book review      C.news report         D.travel guide.
10.Doctors say anger can be an extremely damaging emotion,unless you learn how to deal with it.They warn that anger can lead to heart disease,stomach problems,headaches,emotional problems and possibly cancer.
(71)F Some people express anger openly in a calm reasonable way.Others burst with anger,scream and yell.But other people keep their anger inside.They can not or will not express it.This is called repressing anger.
For years many doctors think that repressing anger is more dangerous to a person's health than expressing it.They say that when a person is angry,the brain releases the same hormones (荷尔蒙).They speed the heart rate,raise blood pressure,or sugar into the blood,etc.(72)A
Some doctors say that both repressing and expressing anger can be dangerous.They believe that those who express anger violently may be more likely to develop heart disease,and they believe that those who keep anger inside may face a greater danger of high blood pressure.
(73)G They say the first step is to admit that you are angry and to recognize the real cause of the anger,then decide if the cause is serious enough to get angry about.If it is,they say,"(74)E Wait until your anger has cooled down and you are able to express yourself calmly and reasonably."
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry.(75)B

A.In general,the people feel excited and ready to act.
B.They say that laughter is much healthier than anger.
C.Expressing anger violently is more harmful than repressing it.
D.Anger may cause you a cancer.
E.Do not express your anger while you are angry.
F.Anger is a normal emotion that we all feel from time to time.
G.Doctors say the solution is to learn to deal with anger.
14.It is generally believed that we are getting cleaned when we step under a shower.We are,but we're also giving a home to lots of tiny little creatures we didn't even know about.A showerhead carries thousands of bacteria called Mycobacterium.These can cause problems like coughs and tiredness,and a general feeling of poorliness (身体不舒服).When you turn on the water,the bacteria go from the showerhead onto and into your body.
This is a finding of Norman R.Pace and his team at the University of Colorado,in the US.The scientists investigated bacteria in all kinds of human environment,including showers.Pace's team looked at 45showerheads in nine American cities.They discovered that 30percent of them had large amounts of flying Mycobacterium.
But Pace said that they  pose few threats to the health.Only those with a weak immune system might need to worry.He told the New York Times that the bacteria are not as unpleasant as might be thought.He said that having a shower is no more dangerous than anything else we do in the morning.
But for those who feel sick about the idea of all those microorganisms (微生物),he had some advice.Let the water run for 30seconds before getting into the shower.Why?The number of bacteria is smaller than that when the water is just turned on.If that seems like a waste of water,he added that you could also change your showerhead every few months.
However,Pace had good news too.He has also been testing the air in US subways.Apart from iron particles (粒子),which are ground off the track by the wheels of trains,subway air is fresh.The reason is that a train's movement pumps fresh outdoor air into the tunnels.
Pace explained that he wanted to understand the natural microbial environments of public places.This kind of knowledge might help discover the microbes to be used in a bioterrorist (生物恐怖分子) attack.

56.From the finding of Norman R.Pace,after taking a shower,we might cough or feel tired
becauseB.
A.it's easy to get a cold when taking a bath
B.the showerhead carries many bacteria causing illness
C.we don't get cleaned while showering
D.we don't get a weak immune system
57.According to the passage,which of the following is TRUE?D.
A.Hot water could kill most of bacteria in showerheads.
B.Of 45showerheads surveyed in nine cities,30carried large amounts of Mycobacterium.
C.Changing showerheads is the only way to avoid microorganisms.
D.Shower water contains much less bacteria after being left to run for 30seconds.
58.We can learn from the third paragraph thatC.
A.having a shower in the morning is more dangerous than at other time
B.the bacteria always threat people's health
C.there is no reason to fear microorganisms for people with strong immune system
D.it is better to do some exercise in the morning than have a shower
59.The underlined word"pose"in the third paragraph probably means"A".
A.cause                B.avoid       C.describe           D.promise
60.What contributes to fresh air in US subways?A.
A.The train's movement.B.Iron particles.
C.Train wheels.D.Air conditioners on the trains.
