Find Ways to Respond to a Major Disaster
When natural disasters like hurricanes and earthquakes happen,there’s always a great need for coordinated(协调的) disaster relief and recovery. 1
Volunteer
To take a hands-on approach to disaster recovery,volunteer your time and talents.You can travel to the affected regions to provide support. 2 It is recommended that you volunteer through one of the professional organisations for your safety and your skills can be put to best use.
Donate money
Disaster victims often have lost their homes or need to relocate.In many cases,your money is just as valuable as your physical presence in helping with relief efforts.Many organisations provide temporary housing,food and other items for victims. 3 Even organisations like the Red Cross have been criticised for how donated funds have been allocated(分配).
Donate blood
If you can’t travel and don’t feel comfortable giving money,a need for donated blood always existed.The Red Cross and local medical organisations manage blood supplies that are important to disaster victims.Call the Red Cross to schedule an appointment. 4
5
Goods are valuable in stricken areas.Building materials and donations of bottled water or household items can be placed on trucks and taken to the disaster areas.It is the best to allow the professional organisations to coordinate these donation efforts and see that the needed supplies reach a location where they will be best used for recovery.
A.Send needed items.
B.Make preparations.
C.Or look out for a blood drive in your area.
D.A lot of people are skilful at organising local response.
E.Whether disaster has occurred at home or abroad,you can help.
F.Before giving,though,make sure you trust the organisation receiving your money.
G.And you can do everything from providing first aid to rebuilding homes in these areas.

You can’t hide a natural disaster from children,so how do we prepare them for it First of all,you should explain to them that acts of nature aren’t necessarily disasters but can become one.These may include floods,hurricanes,tornadoes,winter storms,wild fires,and earthquakes.The way to prepare children for these disasters is to educate them about what each type is and then make it fun by making them “Disaster Masters” or whatever title you can think of.
Making them a Disaster Master won’t be easy.They must know what’s in a disaster emergency kit(工具箱) and why it’s included.You can get your friends involved,too.If your friends have children,they may want to be involved in your emergency preparations.Make it a group project.This is the opportunity for everyone to become familiar with the equipment.
We have to be aware of our conduct and the way we react to stress.The children will be easily influenced by your attitude and demeanor,the calmness,steady manner,and good humour of your spouse(配偶) and you will go a long way towards the easing or the reduction of stress.
Explain to them what they’re likely to encounter or see and describe how people may react.Disasters can come and go very quickly and generally don’t last long.If you must stay away from home,try to get into a routine quickly and encourage them to make new friends.Let them know they can look to their parents and other adults if they become scared or confused.And it’s important to let them know it’s OK to cry during a disaster.
It’s sometimes helpful to let the children draw pictures of what they’ve experienced.Encourage them to write what they learned and what could have been done better.Save the story.Make it part of a documented family history!
1.This passage was written mainly to tell us about .
A.the importance of mutual help in disaster preparation
B.tips for preparing children for a natural disaster
C.the importance of educating children about natural disasters
D.ways to raise children’s courage in natural disasters
2.It is a must that a Disaster Master knows .
A.when a natural disaster will come
B.why there are natural disasters
C.how to use a disaster emergency kit
D.how to teach others about emergency preparations
3.The underlined word “demeanor” in Paragraph 3 can be replaced by “ ”.
A.personality B.lifestyle
C.emotion D.behaviour
4.When they meet with a natural disaster,children .
A.must write down what they see and how they feel
B.should believe that the disaster will never last long
C.can cry if they are frightened
D.should help other children despite the danger

Are we aware in protecting the environment 1 Let’s take a review of how important environment is and how to protect it.
2
There are many organisations,at a local,national and international level devoted to the environmental protection.Together they form the Green Movement.
Whenever a habitat is threatened(威胁) by industry or development,the Green Movement takes the side of the environment.These groups already enjoy considerable public support. 3 Unless people understand how threats to the environment affect them,they cannot see the importance of environmental protection.
Encourage organic(有机的) farming.
Farming without chemicals is known as organic farming.In several countries,organic produce has become very popular.Because no chemicals are used to grow the food,there are none to enter the human food chain. 4
Save the Rainforest.
In developing countries,action is finally being taken to save the rainforests.In Africa,the Ivory Coast recently banned all timber exports.In Central America,the government of Panama made it illegal to cut down any tree more than five years old. 5 As everybody knows,timber exports have been a major source of income for them.
It is difficult to persuade poor people in developing countries of the importance of saving the forests.They need more food and want to use the land to grow crops on.What matters is not just our enjoyment of nature,but the future of life on Earth.
A.But their most important work is education.
B.Is there anything we can do about it
C.Why are people determined to take actions
D.Join the Green Movement.
E.Such actions show great determination.
F.Found organisations to protect our environment.
G.In addition,people think it will save the environment.

The African elephant,the largest land animal remaining on Earth,is of great importance to African ecosystem(生态系统).Unlike other animals,the African elephant is to a great extent the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(稀树草原) surroundings in which it lives,therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbrushes,and pulls branches off big trees.This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.
1.What is the passage mainly about
A.Disappearance of African elephants.
B.Forests and savannas as habitats for African elephants.
C.The effect of African elephants’ search for food.
D.The eating habit of African elephants.
2.What does the underlined phrase “setting the terms” most probably mean
A.Fixing the time.
B.Worsening the state.
C.Improving the quality.
D.Deciding the conditions.
3.What do we know about the open spaces in the passage
A.They result from the destruction of rain forests.
B.They provide food mainly for African elephants.
C.They are home to many endangered animals.
D.They are attractive to plant-eating animals of different kinds.
4.According to the passage,which of the following statements is TRUE
A.The African elephant is the largest animal on Earth.
B.African elephants have 300 pounds of plants every day,including small trees and underbrushes.
C.The African elephant is in a way the builder of the environment like other land animals.
D.If the African elephant disappears,the whole ecosystem won’t be affected.

By the end of the century,if not sooner,the world’s oceans will be bluer and greener thanks to a warming climate,according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton.Because of the way light reflects off the organisms,these phytoplankton create colourful patterns at the ocean surface.Ocean colour varies from green to blue,depending on the type and concentration of phytoplankton.Climate change will fuel the growth of phytoplankton in some areas,while reducing it in other spots,leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface,where they pull carbon dioxide(二氧化碳)into the ocean while giving off oxygen.When these organisms die,they bury carbon in the deep ocean,an important process that helps to regulate the global climate.But phytoplankton are vulnerable to the ocean’s warming trend.Warming changes key characteristics of the ocean and can affect phytoplankton growth,since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz,a scientist in MIT’s Centre for Global Change Science,built a climate model that projects changes to the oceans throughout the century.In a world that warms up by 3℃,it found that multiple changes to the colour of the oceans would occur.The model projects that currently blue areas with little phytoplankton could become even bluer.But in some waters,such as those of the Arctic,a warming will make conditions riper for phytoplankton,and these areas will turn greener.“Not only are the quantities of phytoplankton in the ocean changing,”she said,“but the type of phytoplankton is changing.”
And why does that matter Phytoplankton are the base of the food web.If certain kinds begin to disappear from the ocean,Dutkiewicz said,“it will change the type of fish that will be able to survive.”Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable,but they could mean significant changes.“It’ll be a while before we can statistically show that the changes are happening because of climate change,”Dutkiewicz said,“but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
5.What are the first two paragraphs mainly about
A.The various patterns at the ocean surface.
B.The cause of the changes in ocean colour.
C.The way light reflects off marine organisms.
D.The efforts to fuel the growth of phytoplankton.
6.What does the underlined word“vulnerable” in Paragraph 3 probably mean
A.Sensitive. B.Beneficial.
C.Significant. D.Unnoticeable.
7.What can we learn from the passage
A.Phytoplankton play a declining role in the marine ecosystem.
B.Dutkiewicz’s model aims to project phytoplankton changes.
C.Phytoplankton have been used to control global climate.
D.Oceans with more phytoplankton may appear greener.
8.What is the main purpose of the passage
A.To assess the consequences of ocean colour changes.
B.To analyse the composition of the ocean food chain.
C.To explain the effects of climate change on oceans.
D.To introduce a new method to study phytoplankton.

Everyone hates being stuck in a traffic jam,but sadly,many people have to deal with it every day.Whether you’re the driver or a passenger,there are steps you can take to help you handle it.
1 This will help if you’re stuck in a long traffic jam and get hungry,and it’s honestly a pretty good time waster,too.Try to bring food that won’t make a mess in the car!If you’re drinking anything sugary or sweet,be careful of spilling(洒出).
Play a road game.Playing a road game is a great way to get rid of the boredom. 2 I Spy is a very popular road game where you say “I spy with my little eyes something that is...” and you say the colour of the object you’ve chosen,and the others have to guess what it is.
Take a breath. 3 If you don’t feel comfortable in a serious traffic jam where the cars aren’t moving at all,just roll down the window or even open the door (if it’s safe to do so),and take a breath beside your car for a second.This can help you feel better if you’re carsick.
4 There are plenty of other things you can do while being stuck in a traffic jam!Ask the driver to go to a good radio station and start calling in and get involved(参与).No matter who’s watching you,sing along to the song on the radio at the top of your voice and dance around in your seat to the song!Start a conversation with the person in the car next to you! 5
A.Get creative with your free time.
B.Pack some snacks before you go.
C.Talk to your doctor about carsickness.
D.Try thinking about something important in the traffic jam.
E.Many people experience car sickness in a long journey.
F.There are lots of games that are fun and enjoyable for everyone!

I was desperately nervous about car-free.But eight months ago our car was hit by a passing vehicle and it was destroyed.No problem,I thought:we’ll buy another.But the insurance payout didn’t even begin to cover the costs of buying a new car—I worked out that,with the loan(贷款) we’d need plus petrol,insurance,parking permits and tax,we would make a payment as much as £600 a month.
And that’s when I had my fancy idea.Why not just give up having a car at all I live in London.We have a railway station behind our house,a tube station 10 minutes’ walk away,and a bus stop at the end of the street.A new car club had just opened in our area,and one of its shiny little red Peugeots was parked nearby.If any family in Britain could live without a car,I reasoned,then surely we were that family.
But my new car-free idea,sadly,wasn’t shared by my family.My teenage daughters were horrified.What would their friends think about our family being “too poor to afford a car” (I wasn’t that bothered what they thought,and I suggested the girls should take the same approach.)My friends,too,were astonished at our plan.What would happen if someone got seriously ill overnight and needed to go to hospital (an ambulance) How would the children get to and from their many events (buses and trains) People smiled as though this was another of my mad ideas,before saying they were sure I’d soon realise that a car was a necessity.
Eight months on,I wonder whether we’ll ever own a car again.The idea that you “have to” own a car,especially if you live in a city,is all in the mind.I live—and many other citizens do too—in a place that has never been better served by public transport,and yet car ownership has never been higher.We worry about rising car costs,but we’d be better off asking something much more basic:do I really need a car Certainly the answer is no,and I’m a lot richer because I dared to ask the question.
1.The author decided to live a car-free life partly because .
A.most families chose to go car-free
B.he was hurt in a terrible car accident
C.the traffic jam was unbearable for him
D.the cost of a new car was too much
2.What is the attitude of the author’s family towards his plan
A.Supportive. B.Disapproving.
C.Optimistic. D.Unconcerned.
3.What did the author suggest his daughters do about their friends’ opinion
A.Argue against it. B.Take their advice.
C.Leave it alone. D.Think it over.
4.What conclusion did the author draw after the eight-month car-free life
A.Life cannot go without a car.
B.His life gets improved without a car.
C.Life without a car is a little bit hard.
D.A car-free life does not suit everyone.

The twentieth century saw greater changes than any century before.Changes for the better,changes for the worse,changes that brought a lot of benefits to human beings,changes that put man in danger.Many things caused the changes,but,in my opinion,the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views.It has given us a deeper knowledge of the structure of matter and of the universe.It has brought us a better understanding of the nature of life and of its continuous development.Technology in the application of science has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings;in pure science—a wider and deeper knowledge in all fields of learning;in applied science—a more reasonable sharing of material benefits,and better protection of the environment.
Sadly,however,there is another side to the picture.The creativity of science has been employed in doing damage to mankind.The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet.We have seen this happen in the case of nuclear weapons.Although their actual use has so far occurred only in the Second World War,the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used,the result could have been the ruin of the human race,as well as of many kinds of animals.
William Shakespeare said,“The web of our life is of a mingled yarn(纱线),good and ill together.” The above brief review of the application of only one part of human activities—science—seems to prove what Shakespeare said.But does it have to be so Must the ill always go together with the good Are we biologically programmed for war
5.Which of the following best shows the structure of the passage
6.What can we infer from the fourth paragraph
A.A great many nuclear weapons were actually used for war.
B.A large number of nuclear weapons should have been used for war.
C.The author is doubtful about the ruin of human beings by nuclear weapons.
D.The author is anxious about the huge number of nuclear weapons on the Earth.
7.What does the underlined word “mingled” most probably mean
A.Simple. B.Mixed.
C.Sad. D.Happy.
8.What do you think the author is most likely to suggest if he continues to write
A.Further application of science to war.
B.More reading of William Shakespeare.
C.Proper use of science in the new century.
D.Effective ways to separate the good from the ill.

Cleaning up the existing damage to our environment and preventing further destruction is a huge job.It can seem that there is no way one person,especially a young person like you,can make a difference. 1 ,starting with changing some simple everyday habits and working with others to spread the importance of protecting the environment.Here are a few suggestions.
●Avoid unnecessary driving or being driven.Every teenager looks forward to a driver’s license and a first car,but automobiles are one of the primary causes of air pollution.If it’s too far to pedal a bike,take a bus or share your car ride with someone else. 2 ,but it undoubtedly benefits the environment more.
●Unplug electrical equipment when possible.Even when turned off,some appliances may still use power. 3 .So it is best to unplug anything that you do not expect to use in the next 36 hours (or more).
●Carry a bag and a reusable water bottle. 4 .On the contrary,plastic bags and disposable bottles may bring convenience to you,but the environmental damage caused by them is almost permanent.Every plastic bottle not made and plastic bag not used helps a little bit.
●Raise awareness.Talk to family and friends about simple changes they can make,and why they should do so to help protect the environment. 5 .It’s acceptable to just show them that you have thought a lot about the subject,are passionate about making a difference,and really could use their support.
A.But you can make your contribution
B.It might not seem as cool as driving yourself
C.This saves your money with fewer trips to the gas station
D.They don’t take up much space but can prevent a lot of waste
E.You don’t have to give lectures or force them to accept your opinions
F.They may be the secret sources of the large number on your electric bill
G.This can help start a dialogue in your community about a particular environmental issue

Striking footage(镜头) recorded for NationalGeographic shows a dying polar bear struggling to find food on a land without ice or snow.The poor creature can be seen dragging its bony frame(骨架) across the rough land and searching for food in a bin.
Paul Nicken,the photographer who shot the heart-breaking footage,says the sight reduced him to tears.“We stood there crying—filming with tears rolling down our cheeks,” he said.They found the dying creature on Canada’s Baffin Island—an area that has seen an extreme reduction in sea ice because of global warming.
Nicken says that had he stepped in,it would only have deepened the situation.Instead,he filmed the bear’s slow,painful death and posted it to social media to serve as visual proof of the impact of climate change.“When scientists say bears are going extinct,I want people to realise what it looks like.Bears are going to starve to death,” said Nicken.“This is what a starving bear looks like.”
Polar bears are only native to the Arctic region and are one of the many casualties(伤亡) of climate change.They rely on the Arctic ice to hunt seals and are becoming increasingly threatened as the ice melts away.
The World Wildlife Fund(WWF) predicted back in 2002 that polar bears may face extinction for losing habitat.There are an estimated 25,000 bears left in the wild and most experts agree that unless climate change is controlled,they will all be dead within the next 100 years.“The simple truth is this—if the Earth continues to warm,we will lose bears and the entire polar ecosystem.This large male bear was not old,and he certainly died within hours or days in that situation,” Nicken wrote on Instagram.But there are solutions.We must begin putting the Earth—our home—first.
