3.Many of us may be eating food containing GM(转基因的) ingredients without realizing it.Are GM foods safe for people?Can they help solve the poverty problem?They have been the subjects of a hot debate.
This debate is related to increasing challenges from rising climatic change,population growth,urbanization,and natural resource consumption.According to the Food and Agriculture Organization,food production needs to increase by 60percent by 2050in order to feed 9billion people.Scientists and policymakers are searching for effective ways to gain nutritious food,for today and future.Unlike previous agricultural methods (such as the Green Revolution),GM crops are to fight food safety and poverty challenges.
The great expansion of GM crop varieties over the last two decades can be seen easily.The total area devoted to GM crops has increased 100times from 1.7million hectares in 1996to 170million hectares in 2012.Developing countries now grow more GM crops than developed countries (in terms of area),largely driven by Brazil's rapid adoption of GM crops.China is home to about 4percent of the total global area devoted to GM crops.Beans,corn,and cotton are main global GM crops,while China's focus is on cotton,papaya,and poplar.
Recently,a scientific study shows that GM crops are safe for people and the     environment.According to a 2010report on the safety of GM crops by the EU,"the main conclusion to be drawn from the efforts of more than 130research projects,covering a period of more than 25years of research,and involving more than 500research groups,is that biology methods,are not more risky than traditional planting technologies,for example."Other international and national scientific bodies,such as the World Health Organization,have reached the same conclusion.
24.As for GM crops,what do people mainly focus on?C
A.Food production.
B.Food nutrition.
C.Food safety.
D.Food variety.
25.What does Paragraph 3talk about?D
A.More GM crops in developing countries.
B.Less GM crops in developed countries.
C.Rapid adoption of GM crops in Brazil.
D.The expansion of GM crop varieties of the world.
26.From a recent scientific study,we can infer thatB.
A.traditional planting technologies are more risky
B.the safety of GM crops has been proved in many ways
C.the safety of GM crops was reported by the EU in 2010
D.present GM crops are safe for people and the environment
27.What's the writer's attitude towards GM crops?A
A.Supportive.
B.Opposed.
C.Unknown.
D.Indifferent.

13.Life learning ( sometimes called un-schooling or self-directed learning) is one of those concepts that are almost easier to explain by saying what it isn't,than what it is.And that,s probably because our own schooled backgrounds have convinced us that learning happens only in a dedicated building on certain days,between certain hours,and managed by a specially trained professional.
Within that schooling framework,no matter how hard teachers try and no matter how good their textbooks,many bright students get bored,many slower students struggle and give Up or lose their self 一 respect,and most of them reach the end of the process unprepared to enter into society.Hiey have memorized a certain body of knowledge long enough to rush back the information on tests,but they haven't really learnt much,at least of the official curriculum.
Life learners,on the other hand,know that learning is not difficult9 that people learn things quite easily if they,re not compelled and forced,if they see a need to learn something,and if they are trusted and respected enough to learn it on their own timetable,at their own speed,in their own way.They know that learning cannot be produced in us and that we cannot produce it in others-no matter what age and•no matter whether we,re at school or at home.
Life learning is independent of time,location or the presence of teacher.It does not require mom or dad to teach,or kids to work in workbooks at the kitchen table from 9 to noon from September to June.Life learning is learner-driven.It involves living and learning 一 in and from the real world.It is about exploring,questioning,experimenting,making messes,taking risks without fear of making mistakes,being laughed at and trying again.
Furthermore,life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways.It is about providing positive experiences that enable children to understand the world and their culture and to interact with it.
47.It is implied from the passage that it is difficult toC
A.find a specially trained teacher
B.learn without going to school
C.tell the nature of life learning
D.carry life learning through
48.What does the writer say about the schooling framework?C
A.It often gives little care to the quality of teaching materials.
B.It often fails to provide enough knowledge about life.
C.It often ignores some parts of the official curriculum.
D.It often produces slow students with poor memories.
49.Life learners recognize that learning will not be hard if they areB.
A.cautious about any mistakes      B.clear about why to learn
C.careful to make a time table     D.able to respect other people
50.According to the author,which of the following is true about life learning?B
A.It teaches a kid how to avoid being laughed at.
B.It could be a road full of trials and errors.
C.It makes a kid independent of his parents.
D.It could prevent one from running risks.
14.Forcing children to learn will not improve their development or raise their chances of  getting into elite schools,an educator at an international school has warned.
Hong Kong parents like to fill their children's schedules each day with extracurricular  lessons,such as piano,swimming and painting.Parents hope the additional skills will help  their children stand out in admissions interviews for the top schools.
"It's good to expose your child to possibilities,but it's not good to keep pushing them  to try things."said Professor Deborah Eyre,education director of Nord Anglia Education,which opens an international school in Lam Tin."You also want children to think,reflect and develop themselves as individuals."
"We value what parents do.We know that they're trying to do the best for their child.But what's important is that children come to school loving learning and wanting to learn,"Eyre said.
It has been reported that some parents enroll their children in two kindergartens-an  English-language one in the morning and another one in Chinese in the afternoon.
"For children,it's important to have good education but'it's also important that they  have more informal learning which they do with their family,"Eyre said."If you want your  child to have a good vocabulary,you can read and talk to your child.They will learn better  with you than they would in a kindergarten."
Eyre,a former director of the UK government's academy for gifted youth,offered the  example of Scandinavian countries such as Norway,where children do not formally take part in reading or writing until the age of seven.Rather than negatively affecting their  development,it helped them get to know the world.
"Internationally,the educator's role is to introduce some formal learning but also to  value play and discovery with young children who are trying to understand the world around them."she said.We need to help them to discover for themselves.

28.What does the word"elite"in Paragraph 1refer to?C
A.Primary.    B.High.    C.Top.    D.Average.
29.What can we know about Hong Kong parents?B
A.They usually adjust the subjects to their children's taste
B.They hope their children have more skills
C.They think it's no good pushing their children to try new things
D.They teach their children how to be independent
30.From Eyre's point of view,how can children have a good vocabulary?A
A.Being exposed to parents'reading and talking.
B.Talking with their peers.
C.Using more new words from an early age.
D.Learning carefully in the kindergarten.
31.What can we know in Norway?D
A.Children have no access to books before the age of seven.
B.The current educational approaches negatively affect children's growth.
C.Play is classified as formal learning.
D.Children are encouraged to understand the world.
11.Parents do need to teach their kids financial responsibility and that money is earned.Still,many child-development experts agree that tying a child's pocket money to chores(琐事) can be a slippery slope.Here's why.
Susie Walton,master instructor at Peace in Your Home advises to keep chores and pocket money totally separate."Pocket money is one thing.When it comes to chores,life skills,responsibilities-that's a whole different thing."says Walton.
Walton says,"When kids aren't doing a chore,you don't say,‘well,there goes your pocket money.'You're going to sit them down and ask what's going on.‘We are a team.We are a family.We've got to have them done.'"
Besides,by paying children for chores with pocket money,you'll also be sending the message that work isn't worth doing unless they're getting paid for it.
There are times when it would make sense to pay kids for chores.Most financial and child-development experts agree that it's a fine idea to pay children money for extra jobs that are outside their normal set of chores,such as washing windows,washing the car or helping to clean out the garage-especially if the child is saving for a big item.This may even develop an entrepreneurial (企业家的) spirit to think outside of the box to earn money.
For parents who are concerned that their children won't learn the value of a dollar if the pocket money isn't tied to household chores,note that there are still plenty of money management skills to be learned from a straight allowance.Depending on the age,kids can be made responsible for paying for their own toys or snacks.Some parents even require that kids set aside a percentage of their pocket money toward savings.
"I really like having my own money,"says Kevin,9"It's up to me if I want to buy the cheap toy now,or save and get the better toy."And that's a good lesson to learn at 9years old.
No matter which pocket money route you take in parenthood,kids will feel empowered by being able to handle their own money.
24.According to Susie Walton,if kids don't do chores,parents shouldB.
A.teach them the entrepreneurial spirit
B.talk to them about family responsibilities.
C.give them a smaller pocket money than usual
D.order them to give a reasonable explanation
25.In Paragraph 6,"a straight allowance"probably means"D".
A.money given by charity organizations
B.money earned by doing part-time jobs.
C.money earned by doing everyday household chores
D.money given by parents and not dependent on chores
26.What is the author's attitude towards Kevin's action?C
A.Worried.
B.Doubtful.
C.Approving.
D.Unfavorable.
27.The text is mainly aboutB.
A.the importance of kids doing chores
B.whether parents should pay kids for chores
C.Whether it is good or bad to give kids pocket money
D.whether parents should give kids regular pocket money.
18.It took 100years,but finally,scientists proved Albert Einstein's theory that gravitational waves exist.
The waves were predicted as part of Einstein's General Theory of Relativity nearly 100years ago.It was the theory of the physics behind the workings of our world and the universe.The idea was that the waves are like ripples(涟漪)in space,caused by some of the violent and energetic processes in the Universe.For example,two black holes crashing into each other.
Now a group of scientists,including ones from CalTech,MIT and the LIGO Scientific Collaboration finally found the gravitational waves.
David Reitze is the executive(有执行权的)director of the LIGO observatory(天文台) at CalTech."We have detected gravitational waves.We did it!"Reitze spoke with others at a press conference in Washington,DC this past week.The scientists announced they were able to see ripples in the fabric(织物)of space time.
What are these gravitational waves?Well,imagine throwing a rock into a pond.When the rock hits the flat surface of the water,it creates ripples or waves.Space time is like the surface of the water.So that means gravitational waves are like the ripples moving out from where the rock hits the water.
It might be hard to understand,but those gravitational waves expand and contract space and time as they move through space.And when they get to the Earth,the waves pass through,and contract and expand the planet as the wave goes by.
It was Einstein who said these gravitational waves should be observable.But these are not huge waves.They are very,very small,which is why it took so long to find them.You cannot see them with your eyes.They are smaller than the size of an atom.
How did the scientists find them?They used a giant scientific tool called LIGO-which stands for the Laser Interferometer Gravitational-Wave Observatory.The billion-dollar LIGO project is two L-shaped observatories.One is in Louisiana and one in Washington state.Their job was to watch for these gravitational waves.They have been looking on and off since 2002.
For years,scientists have been watching two black holes in another galaxy(银河)faraway.The two were spinning around each other,moving closer and closer together.When they finally crashed into each other,it was with such power and force,that gravitational waves rang throughout the universe,like a giant bell.Those waves,traveling at the speed of light,finally reached the Earth,some 1.3billion years later.They are the same waves that the scientists announced this past week.Each of the black holes was thought to be 29to 36times the mass of our sun.
So,what does this discovery mean?
Abhay Ashtekar is a Penn State physicist,who was not on the discovery team.He said:"Our understanding of the heavens changed dramatically."

24.According to the text,which of the following statements is true?C
A.Gravitational waves have been existing for 100years.
B.Albert Einstein proved the existence of gravitational waves.
C.Gravitational waves travel as fast as light.
D.Albert Einstein predicted the existence of black holes.
25.What can be inferred from the text?A
A.The LIGO project costs a lot of money.
B.The LIGO project is directed by Abhay Ashtekar.
C.The LIGO has been watching for gravitational waves continuously.
D.The LIGO observatory is intended to detect black holes.
26.What is the text mainly about?B
A.Einstein's General Theory of Relativity.
B.The detection of gravitational waves.
C.David Reitze's LIGO project.
D.The crash of two black holes.
27.The underlined word"contract"probably meansB.
A.make a legal agreement with someone
B.become shorter or narrower or smaller
C.catch or develop an illness
D.communicate with someone.

11.The weather predictions for Asia in 2050read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring.In the decades to come,Asia---home to more than half the world's 63billion people-will change from one climate extreme to another,with tired farmers battling droughts,floods,disease,food shortages and rising sea levels.
"It's not a pretty picture,"said Steve Sawyer,climate policy adviser with Greenpeace in Amsterdam.Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already,changes are being felt in Asia but worse is likely to come,Sawyer and top climate bodies say,and could lead to mass migration and widespread human disasters.According to predictions,icebergs will melt faster,some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses,storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food,water and other resources.Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
