12.Though Alberta's Banff National Park is home to a large and healthy wildlife population,it also welcomes about 3.5million visitors every year.Besides,4.5million humans drive through without stopping,all passengers on the busy Trans-Canada Highway that cuts through the park.That's why roadkill(animals that have been killed by cars on the road) was a common sight on the world's longest national road.
Banff first put up wildlife fencing on each side of the highway.Then,since 1996,they've opened six wildlife overpasses and 38underpasses,which have allowed for more than 140,000wild life crossings.
Though these crossings are normally closed to all humans,as a tourists I was lucky to be allowed to see Banff's Red Earth Overpass with road ecologist(生態(tài)學(xué)家) Trevor Kinley.As a project manager with Parks Canada,he told me that so far,they have recorded 10,000safe animal crossings on this overpass alone.That's 10,000animals lives saved and a whole lot of roadkill prevented.
Labib Salama,an animal lover,worries that forcing so much wildlife into using just a few bridges and tunnels(passages under the ground) is putting some animals'lives into danger.They probably become easy meals for their natural enemies on either side.However,the truth is that there are no more killings around the crossings than there are anywhere else in the park.
Walking over the Red Earth Overpass,I was surprised how natural the area seemed.The noise disappeared,as did the road.The forest has filled in the area so that anyone crossing would really have no idea they were crossing a main highway along the way,I found the fresh tracks of black bears,grizzlies,wolves,elk,deer,and marten.Somehow,all these animal tracks made me so happy,knowing that they were passing safely under and over the longest road in Canada.
21.What was the problem facing Banff National Park?C
A.Some animals were in danger of dying out
B.Too many people went to visit the park.
C.Highway cars took many animals'lives.

A.fall off the bridges         
B.be killed by passing cars
C.be eaten by others easily    
D.refuse to use the tunnels
23.How is the area around the Red Earth Overpass?A
A.Quiet   
B.Dry   
C.Dirty  
D.Dangerous
24.What does the author think of the Wildlife crossings in Banff?D
A.They've made it easier for visitors to walk around.
B.They've destroyed the environment in the park.
C.It is a waste of money to build them.
D.It is a good way to protect animals.

20.It's no secret that doing good makes others happy-but did you know it can make you happy as well?According to a study,people participating in meaningful activities were happier and felt that their lives had more purpose than people who only engaged in pleasure-seeking behaviors.1(36)D
●Your Attention
Most of us think we're good listeners,but according to psychologist Paul Donoghue,most people are aware that others don't listen as well as they could.(37)A
●Your Money
According to an experiment,those who spend money on other people are significantly happier than those who spend the same quantity of money on themselves.(38)G
It represents time spent,compassion and careful attention to the needs of others.
(39)B
The psychological meaning of compassion is the ability to understand another person's emotional state.Compassion differs from empathy(移情) in that those who experience compassion not only put themselves in another person's shoes,but also want to reduce that person's suffering.
A brain-imaging study showed that the brain's pleasure centers are equally active when we give money to the poor as when we receive money ourselves.
●Your Time 
 (40)F
However,volunteering your time has great benefits,including making new friends and connections,learning new skills and even advancing your career.
According to a paper about the link between health and volunteering,volunteering is connected with lower instances of depression and reduces the risk of dying by 22 percent.
 
A.In addition,they're not fully aware that they themselves aren't listening.

1.Animals have been killed for their fur and feathers,and(61)thousands(thousand) of kinds of animals have disappeared from the world forever.About 170kinds in the US alone (62)are considered  (consider) in danger.
Why should people care?(63)Because  we need animals,and if they are gone,there will never be any more.Every animal has its place in the balance of nature.(64)Destroying(destroy) one kind of animal can create many problems.For example,when farmers killed large numbers of hawks (老鷹),the farmers'stores of corn and grain were destroyed(65)byrats and mice.With no hawks to keep down their numbers,the rats and mice multiplied (繁殖)(66)quickly(quick).
Luckily,some people are working(67)to help(help) save the animals.Some groups raise money to let people know about(68)theproblem.And they try to get the governments to pass laws protecting animals in danger.Quite a few(69)countries(country) have passed laws.These laws forbid the killing of any animals on the danger list.Slowly,the number of some animals in danger(70)is(be) growing.

2.With the (41)development (develop) of industry,air pollution is getting more (42)and more serious.In Beijing,many people suffer different kinds of illnesses because (43)of air pollution.
Air pollution is caused by the following (44)reasons[reason]:about half (45)of the problem is caused by vehicles(車輛).There are more and more cars,buses on the roads,and they give off poisonous(有毒的) gases.25% of air pollution is caused by factories.Another factor is the smokers.
(46)Smoking[Smoke]not only does harm to their health but also to others.Besides these,about 10%of air pollution is caused by other reasons.
We should take some measures to fight (47)against pollution.New fuel[燃料]can(48)be used[use]to replace[代替]gas.We can plant more trees.(49)If everybody realizes the importance of environment and does something to stop pollution,(50)the problem will be solved.
