19.Ecotourism is a combination of ecology (the study of systems of living things) and tourism.It is (51)A"responsible travel to natural areas that preserves the environment and improves the welfare of the local people"by the International Ecotourism Society.Actually,ecotourism can mean travel to far-off places of great natural beauty,but not always in a(n) (52)Dway.It's a big business,and the attraction of money can cause people to think about (53)C first.While ecotourism offers benefits to people and ecosystems,it leaves ecosystems open to negative effects,too.
Costa Rica,once a Spanish colony,and independent since 1821,has an ecotourism industry worth over one billion dollars yearly,and thousands of jobs have been (54)B.Nearly 21percent of the land is now protected national parks,(55)A thanks to ecotourism.Nevertheless,due to the number of people visiting the country's natural places,some damage to the ecosystem has occurred.
While (56)A can have a negative impact on ecosystems,the same areas might have been (57)B by industries such as farming,logging,or mining if there were no ecotourism industry.Shelters (庇护所) have been created (58)C,keeping the ecosystem protected.And,by visiting beautiful rainforests and seeing rare animals,visitors get a sense of their (59)D,and of gratitude for them.Tour guides can also be educators who train people to love and care for the environment.Visitors can take these (60)B with them to their home countries.
Unfortunately,while their effect may not be(61)B in the off-season,the constant parade of visitors in the high season can be damaging.At one national park in Costa Rica,wild monkeys now feed on garbage left by the tourists.(62)C,ecotourists tend to seek out places with the rarest animals and plants,(63)D the most delicate living things.
It is easy to be critical of the ecotourism industry,but it is important to be (64)A as well.Ecotourism can never be"pure".We can't expect zero negative effects on the ecosystem.It is also (65)C to suppose that humans won't go anywhere accessible to them.If protection efforts are maintained and increased,those remaining places of undisturbed nature may be stressed,but they won't be destroyed.

52.D考查形容词.在上一句提到了responsible travel to natural areas 得出,这里填responsible上下文同源词复现.
53.C考查名词.the attraction of money人们对钱的吸引,所以首先想到的是利益.
54.B考查动词.这句讲的是生态旅游给当地带来的好处,即创造了很多就业机会.

57.B.考查动词. farming,logging,or mining if there were no ecotourism industry即使没有大量的游客,农耕,开矿等也会破坏当地的生态.
58.C考查副词.由于大量的游客会破坏当地的生态,所以避难所就出现了,instead此处是副词意思是相反,符合语境.
59.D考查名词.by visiting beautiful rainforests and seeing rare animals通过参观漂亮的雨林和看到稀有动物,游客会产生一种珍惜感,value这里是名词,珍惜的意思.
60.B考查名词.Tour guides can also be educators who train people to love and care for the environment这句话告诉我们游客通过哦旅游会收获很多体会.     
61.B考查形容词.根据Unfortunately,这些影响游客都没有注意到.
62.C考查短语.前面列举了影响,ecotourists tend to seek out places with the rarest animals and plants所以用in addition来引导,表示递进的关系,意思是除此之外,另外.
63.D考查动词.press此处是现在分词做状语表示结果,结果给当地的生物带来了压力.
64.A考查形容词.上文讲的是生态旅游的弊端,但也要有乐观的态度.positive意思是积极的,乐观的.
65.C考查形容词.We can't expect zero negative effects on the ecosystem前句说我们不能忽视生态旅游的消极影响,但是设想人们不去生态旅游也是不现实的.

He told us his life changed that night.He went back to work the next(22)A with a thank-you card to his boss.He said I had(23)B him to look at life from different perspectives and to express gratitude.

9.All over the world,children in hospital are being treated with a new kind of medicine:laughter.Lucy is 23and works for Theodora Children's Trust.She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.
"I'm a Theodora clown doctor.I call myself Dr Looloo.I spend two days a week in children's hospitals,making funny faces,telling jokes,and doing magic tricks.As I walk into the wards I blow bubbles,shake hands with the kids,and make up nonsense songs for those children well enough to sing.I take special balloons to make‘balloon animals'and tell funny stories about them.
I'm naturally a very cheerful person.I've always been a clown.In fact my father's a clown and I started working with him when I was eight years old.I knew it was just the job for me and I became a clown doctor because I think it is a great way to cheer up sick,frightened children in hospital.
Being a clown in hospital is very tiring both physically and emotionally.We have to learn not to show our feelings,otherwise we'd be useless.Clown doctors are sensitive but this is not a side most people see.To the children we're happy all the time.I'm still learning to allow myself to feel sad occasionally.There are special kids you get really close to.At the moment I'm working with a very sick little girl from Bosnia who speaks no English,so our only common language is laughter.
At weekends I participate in events to raise money for Theodora Children's Trust.It's a charity so we are paid with the money people give.Being a clown doctor makes the worries of everyday life seem small.All in all,I feel honoured to do this job."

32.Lucy works as a clown doctor becauseC.
A.her father is a clown            
B.she has been a clown since she was eight
C.laughter is a great help to sick children  
D.working in hospital brings her extra money
33.What do clown doctors usually do in hospital?B
A.Teach kids how to speak English.
B.Cheer kids up with funny stories.
C.Join in activities to raise money.
D.Develop kids'sense of humour.
34.Lucy thinks that being a clown doctor isA.
A.an honourable and meaningful practice    
B.an interesting job to make a living
C.a good way of getting rid of her worries   
D.an experience of great fun
35.The best of the passage may beC.
