11.The past fifty years or so have seen the gradual disappearing of animals from this earth,fishes from the sea,trees and plants from the land.
Many factors result in this unpleasant phenomenon.Among them,hunting is the main factor that endangers wild life.Some people kill wild life for sport.They take pleasure in collecting heads and hides.Yet others specialize in commercial hunting like killing whales.
Apart from this,the rapidly growing human population threatens wild life on land,too.Towns expand and roads have to be built,so forests are burnt and trees are chopped down.It seems that man needs every inch of land within his reach,so he moves on to the natural habitat of wild life.Tigers,lions and leopards slowly die off without the food and shelter that the forests provide.
In addition,rapid urbanization means industrial expansion.Very often,poisonous chemicals,industrial wastes and oil are dumped into the rivers and seas.Fish and birds are threatened.
Man depends greatly on animals for survival.He needs their flesh,hides and furs.Thus,man cannot do without wild life; or he himself would become extinct.The public should be made aware that it would be better to shoot the animals with a camera than with a gun.In this way,they can preserve and help wild life to continue living rather than to remove all signs of it.
Man must learn to farm the sea as he does the land.He should control the amount and the frequency of his catch.He should allow fish to breed and multiply before netting them.Man also needs to build forest reserves,and to pass laws prohibiting the killing of animals,especially those that are already rare.To keep the present animal kingdom,the least that man can do is to clean the seas and rivers and to prevent pollution.
The cycle of nature is such that it forms a vicious circle.The pesticides(杀虫剂) that we spray on crops can kill the birds and animals that feed on them.When man eats these poisoned animals,he himself can die.We must therefore test the chemicals to be used before they are sprayed or it might mean the death of man!

13.The author's purpose in writing the passage is toD.
A.explain how important wild life is to human beings.
B.call people's attention to serious problem of pollution.
C.explain relationship between wild life and human being
D.call people's attention to the protection of wild life
14.Which of the following is NOT true according to the passage?C
A.The growing human population threatens wild life because people take land from animals
B.Some people devote themselves to killing animals for money.
C.People can preserve and help wild life to continue living by shooting the animals with a camera.
D.Fishes are threatened by poisonous chemicals,industrial wastes and oil.
15.The last paragraph is mainly aboutA.
A.the importance of wild life to human beings
B.how the circle of nature is formed
C.how animals are gradually disappearing form the earth
D.how to solve the problem of pollution.

Eat your vegetables. Wash your hands. Always say "please" and "thank you". We are full of advice for our children.1.As a result, our children may grow up with clean hands and good manners, but without any idea how to manage their money.

Here are some basics that will help guide them their entire lives:

Show them the future. If your 13-year-old girl were to save $1,000, invest it at 8% and add $100 every month, by the time she's 65, she would have $980,983!

Be careful of credit. Credit cards can help you buy necessary things and build a credit history, but they must be used responsibly. 2. Explain to your children that when you buy something using a credit card, you can easily end up paying two or three times what you would have paid if you used cash.

3.Suppose your child wants a new bicycle that costs $150. Rather than paying the cash, give him some regular pocket money and explain that by putting aside, say, $15 a week, he will be able to buy it for himself in only ten weeks.

Explain your values. 4.When your child demands that you buy something, explain way you really don't went to buy it. You might say, "I'd rather save that money for your education" 5.

A. Every time you spend or don't spend money, you have a chance to share your values.

B. Provide encouragement.

C. That means paying off your debt in time.

D. Teach patience.

E. Values and money interact.

F. But when it comes to money, we often have little to say.

G. Tell your children the importance of saving.

19.Researchers may have discovered a perfect material of dieting-low fat cake and cheese.British researchers say they have created a protein (蛋白质) that can replace fat perfectly.
The proteins will enable food producers to remove much of the fat used in their products but without reducing product quality.
Funded by team from University of Edinburgh,the researchers have produced the modified (调整了的) proteins that easily break down and therefore work nearly the same as the fats do during food production.
"We've paved the way for the development of modified proteins that can be used to produce a wider range of appealing low-fat foods,"said Dr.Steve Euston,who led the research."The result could be important for health benefits,as well as a reduction in the burden on the National Health Service (NHS) caused by many weight-related health problems."
Protein-for-fat substitution (替代品) is not a completely new idea,but to date it has been limited to products such as yogurts.
In cheeses and cakes it has proved less successful in ensuring the original taste and texture fundamental to consumer satisfaction,mainly because proteins could not mimic the behavior of fats closely enough.
By studying the proteins'chemical structure,the team has developed a detailed understanding of how proteins behave when they are heated or go through other food producing processes.
The proteins could encourage development of a wider choice of low-fat foods,helping consumers to eat more healthily and reducing weight-related health problems.
The team has achieved particularly promising results in using proteins to replace eggs,which is commonly used in bakery items.
Such substitution not only cuts fat content; because eggs can be subject to sharp changes in price.It could also cut the cost products and so encourage consumers to eat more healthily.
32.What can we learn from the passage?A
A.The NHS will benefit from this new finding.
B.The research team is funded by food producers.
C.Protein for fat substitution is a completely new idea.
D.Products of modified proteins have been put on sale.
33.The underlined word"mimic"meansD.
A.reduce        B.make              C.remove D.imitate(模仿)
34.These new proteins work nearly the same as the fats do becauseB.
A.they will cut fat content easily           
B.they will break down easily
C.their products are cheaper and healthier    
D.they ensure the original taste and texture
35. Which of the following is the best title?A
A.A Special Protein                      
B.How Proteins Work
C.Cut Down the Food Cost                
D.A Special Research Team.

6.World travel has moved on to a new level as new websites spring up to enable travelers to plan their trips online.Virtual tourism is the latest name of the game and although relatively new,has seen some tourism websites grow to host over one-million users.
   Typically,this development features a website that contains the answers to almost any tourism question.Tips and information are not provided by a single source,such as the website host,but rather from travelers themselves-often in the thousands.This has proven to be exceptionally beneficial for would-be travelers who are seeking infomtation on questions such as where to find the best museum or beach; whether it is better to tour Brussels with a bicycle or on foot; and which exchange rate bureaus are available in Italy.Questions about food and restaurants; tourist spots; safety; accommodation; and others are all answered.In addition,posted tips promote better preparation,such as what to pack when heading for Sicily(西西里岛).
   Apart from the useful tips,visual images and virtual tours have also been made available.If you'd like to visit the Eiffel Tower,it's a good idea to view the surrounding areas; to pick a safer train route; or to know that it's very close to the Seine River and that a walk along it would enhance the experience.
   Virtual tours have sprung up globally.In South Africa,John Gore established the Virtual Tour Guide in November last year.On his blog,Gore was quoted a saying,"The world is panoramic(全景的)."'We are able to tum our heads and look in all directions and get a feel for where we are,but the typical photograph cannot show or describe that experience completely."However,there is an answer-technology makes it possible to share the world around us in a 360 degree panoramic way,which really makes the viewer feel as though he or she is really there.
67.Why is virtual tourism more and more popular?B
A.Online games are more and more attractive.
B.Many new websites appear and develop fast.
C.More and more people want to travel abroad.
D.It helps travelers save as much money as possible.

A.we can solve any problem on websites          
B.websites offer all the tips and information
C.we can get all our questions answered online     
D.we can get many tips about tourism on websites
69.What does the underlined word"sprung up"most probably mean?A
A.Appeared.B.Moved.C.Competed.D.Reduced.
70.What makes us see the world in a panoramic way?C
A.Information.B.Photograph.C.Technology.D.Virtual images.

20.Forgiveness
Forgiveness is a quality that is difficult to possess.When someone has deeply hurt you,it can be extremely difficult to let go of your hate.However,forgiveness is possible,and it can be surprisingly beneficial to your physical and mental health.People who forgive show less sadness,anger and stress and more hopefulness,according to a recent research.
(56)A Try the following steps:
Calm yourself.(57)G You can take a couple of breaths and think of something that gives you pleasure:a beautiful scene in nature,or someone you love.
Don't wait for an apology.Many times the person who hurt you does not intend to apologize.They may have wanted to hurt you or they just don't see things the same way.
(58)F Keep in mind that forgiveness does not necessarily mean becoming friends again with the person who upset you.
Take the control away from your offender(冒犯者).Rethinking about your hurt gives power to the person who caused you pain.Instead of focusing on your wounded feelings,learn to look for the love,beauty and kindness around you.
(59)C If you understand your offender,you may realize that he or she was acting out of unawareness,fear,and even love.You may want to write a letter to yourself from your offender's point of view.
Don't forget to forgive yourself.(60)E But it can rob you of your self-confidence if you don't do it.

A.How should you start to forgive?
B.Why should you forgive?
C.Try to see things from your offender's angle.
D.Recognize the benefits of forgiveness.
E.For some people,forgiving themselves is the biggest challenge.
F.If you wait for people to apologize,you could be waiting an awfully long time.
G.To make your anger die away,try a simple stressmanagement technique.
