　　Batik is a traditional Indonesian colouring method used to make designs and drawings,
usually on cloth and finished textiles.Batik makers use dyes (染料)—colours added to cloth and other materials—to create the colourful designs.
　　In central Indonesia,many batik makers are using natural dyes instead of manufactured ones.The natural dyes come from mangrove forests (红树林) that grow along the coast.The trees grow in salty water on a complex system of tall roots.
　　Mangrove forests serve an important purpose.They provide a barrier against destructive ocean waves called tsunamis.They are also important to water life like fish and crabs.And the forests are more effective in taking in carbon dioxide,a gas linked to climate change,than rainforests or similar environments.
　　Erwin Ardli is a mangrove ecologist at Indonesia’s Universitas Jenderal Soedirman.He says the natural dyes may not be as bright as manufactured ones.But they are better for the environment.
　　Ardli said,“We’ve seen the interest in natural dyes increasing,and especially for middle class and upper class people,they seem proud to wear clothes using these natural dyes rather than synthetic (合成的) ones.”
　　Iiting Budiarti,who owns an art gallery that shows batik designs,agreed with Ardli,adding that objects with natural dyes can cost two or three times more than the synthetic ones.
　　Forty-eight-year-old Sodikin is a batik maker.Over the past four years,he and his group of batik makers have changed from using chemical materials for dyes to mangrove-based products.The change has reduced their costs and helped the environment.Harvesting involves gathering a handful of what look like string beans—seeds within a covering.Sodikin then takes the mangrove fruit home to make natural dyes from them.
　　“We use natural materials so as to preserve the mangrove forest at the same time,” Sodikin said.“We do not cut down the trees,” he added,“and we only take fruit or leaves that have fallen.”

There are few places on Earth that humans haven’t messed up.Now even Antarctica,the only continent with no permanent human inhabitants,is being altered by us.A study found that the increasing human presence in Antarctica is causing more snow to melt—bad news for a frozen world already battling the effects of human-caused global warming.
　　Black carbon,the dark,dusty pollution that comes from burning fossil fuels,has settled in locations where tourists and researchers spend a lot of time,scientists found.Even the smallest amount of the dark pollutant can have a significant impact on melting because of its very low reflectiveness:things that are light in colour,like snow,reflect the sun’s energy and stay cool; things that are dark,like black carbon,absorb the sun’s energy and warm up.
　　“The snow albedo (反射率) effect is one of the largest uncertainties in regional and global climate modeling right now,” Alia Khan,a snow and ice scientist at Western Washington University,told the journalist.“That’s one of the motivations for the study,to quantify the impact of black carbon on regional snowmelt,which is important for quantifying the role of black carbon in the global loss of snow and ice.”
　　“Antarctica is sitting there pretty much silently all year.But,if it weren’t there,in the state that it is meant to be,the balance that we have in the climate system will no longer be,” Marilyn Raphael,a geography professor said.“Antarctica’s sea ice is also important to maintain a balance in atmospheric circulation,” he added.As waters get warmer,some Antarctic creatures are finding their homes more and more unlivable.
　　“Everything we do has consequences,” Raphael said.“We need to educate ourselves about those consequences,especially in systems that we know relatively little about.We have to be careful that we don’t upset the climate balance.”
【语篇导读】 本文是说明文。文章主要讲述了由于全球变暖,南极洲的环境正发生着变化。
(　　)1.Why can the smallest amount of black carbon have a huge impact on melting
[A]Because it is highly reflective.
[B]Because its dark colour absorbs heat.
[C]Because it produces vast energy.
[D]Because it causes much pollution.
(　　)2.According to Alia,which of the following is one reason for conducting the study
[A]To measure the impact of black carbon on melting.
[B]To quantify the cost of battling against climate change.
[C]To remove the uncertainties of global warming effects.
[D]To urge people to pay more attention to the melting problem.
(　　)3.What is the fourth paragraph mainly about
[A]The changes caused by Antarctic melting.
[B]The methods to stop Antarctic ice melting.
[C]The significance of Antarctic being in its state.

(　　)4.What does Raphael advise people to do

The Amazon Rainforest:A Natural Treasure
Welcome to the Amazon rainforest.As the largest rainforest in the world,it plays a significant role in maintaining the fine balance of the Earth’s ecosystem.
The Amazon rainforest crosses into eight countries and one overseas region of France.With an area of around 6 million square kilometres,the Amazon rainforest is more than half the size of China.The Amazon River,from which the rainforest gets its name,is about 6,400 kilometres in length.On its journey from the mountains to the ocean,the river supports many different ecosystems.1.　　
The forest’s different levels support an unbelievable variety of wildlife.At the bottom,there is a system of roots beneath the ground.Above that is the mass of leaf litter on the dark forest floor.
2.　　　 Then there are the towering ancient hardwoods,and finally the tops of the tallest trees many metres above the ground.Each level of the forest forms its own little world,and is home to different kinds of living things.
More than 1,700 species of birds and mammals hide among the jungle’s plant life.The jaguar (美洲豹) is one example.It has a yellowish-brown coat with black spots.While a significant
number of jaguars survive here,they are only one element of this forest’s food chain.3.　　　
These frogs,in turn,feed on insects which eat leaves and fruit.When a jaguar dies,a tiny army of microorganisms helps break down its body and return the nutrients to the earth.
The Amazon rainforest breathes life into the planet by absorbing carbon dioxide and producing over 20 per cent of all the Earth’s oxygen.4.　　　 Moreover,the Amazon rainforest is a treasure house of species that can be used for food or medicine.Yet there is one major danger to these irreplaceable plants and animals: us.
5.　　　 As the impact of human activities such as agriculture and cattle farming continues to grow and the list of species in danger of extinction becomes longer,we are left with a question: can we afford to damage the “lungs of the planet”
A.They feed on many species,including frogs.
B.Thus,it is often known as the “lungs of the planet”.
C.Rivers tend to be the easiest way to enter the forest.
D.The next level is made up of shorter plants with large leaves.
E.They give this area the richest species of plants and animals on the Earth.
F.Currently the Amazon rainforest emits around 1 billion tonnes of CO2 each year.
G.Over the past 50 years,about 17 per cent of the rainforest has disappeared due to human activities.

　　One possible version:
Dear schoolmates,
Recently,I took part in an activity called “No Plastic in Nature” launched by WWF,aiming to reduce the use of plastic products.
As we all know,plastic products are widely used from households,hospitals to supermarkets,
factories and so on.Useful as plastic products are,overusing and improper treatment do great harm to our lives,which results in a great waste of resources and severe environmental pollution.Even worse,they are likely to pose a threat to public health.
Therefore,I call on every one of you to participate in this activity and do your part to protect our homeland.

When the natural climate changes due to global warming,it can surely affect seals.The majority of them live in the Antarctic region so as the ice is melting,their natural habitat can be seriously affected.These changes don’t take place overnight.They can be the result of many years of additional temperatures in the area.The seals then have to find ways to adapt.
Seals depend on the cool air currents to bring plenty of food for them.When the temperature gets higher,there is less and less food and the seal population starts to shrink.Mothers aren’t healthy enough to feed their babies.Many of them end up abandoned as the mothers have to leave to find their own source of food.
The fact that their desire to produce young can be changed by the warmer temperature is frightening,too.It is also believed that the warmer temperature can allow different diseases and viruses to attack the seals.This is a huge concern as they can rapidly wipe out huge numbers of seals out there.
However,these changes in climate and temperature aren’t all bad for other species of seals.Scientists have found that those living in warmer climates are producing more young due to the changes.Research also shows that the females are moving further to find food and water.When they are out of the reach of the governing males,they are more willing to accept the moves of other males in the group.
This is a piece of good news too,because it means that there will be more selections in the gene pool (基因库) for future generations.It can help the seals as a species adapt to changes in their natural environment more easily.
The climate change problem for seals is directly linked to humans.When we take action to change what we let out into the environment,we will make positive changes for the seals.
However,it is going to take a very long time to reverse (彻底改变) the effects of what has already been done.

The Amazon Rainforest:A Natural Treasure
Welcome to the Amazon rainforest.As the largest rainforest in the world,it plays a significant role in maintaining the fine balance of the Earth’s ecosystem.
The Amazon rainforest crosses into eight countries and one overseas region of France.With an area of around 6 million square kilometres,the Amazon rainforest is more than half the size of China.The Amazon River,from which the rainforest gets its name,is about 6,400 kilometres in length.On its journey from the mountains to the ocean,the river supports many different ecosystems.1.　　
The forest’s different levels support an unbelievable variety of wildlife.At the bottom,there is a system of roots beneath the ground.Above that is the mass of leaf litter on the dark forest floor.
2.　　　 Then there are the towering ancient hardwoods,and finally the tops of the tallest trees many metres above the ground.Each level of the forest forms its own little world,and is home to different kinds of living things.
More than 1,700 species of birds and mammals hide among the jungle’s plant life.The jaguar (美洲豹) is one example.It has a yellowish-brown coat with black spots.While a significant
number of jaguars survive here,they are only one element of this forest’s food chain.3.　　　
These frogs,in turn,feed on insects which eat leaves and fruit.When a jaguar dies,a tiny army of microorganisms helps break down its body and return the nutrients to the earth.
The Amazon rainforest breathes life into the planet by absorbing carbon dioxide and producing over 20 per cent of all the Earth’s oxygen.4.　　　 Moreover,the Amazon rainforest is a treasure house of species that can be used for food or medicine.Yet there is one major danger to these irreplaceable plants and animals: us.
5.　　　 As the impact of human activities such as agriculture and cattle farming continues to grow and the list of species in danger of extinction becomes longer,we are left with a question: can we afford to damage the “lungs of the planet”
A.They feed on many species,including frogs.
B.Thus,it is often known as the “lungs of the planet”.
C.Rivers tend to be the easiest way to enter the forest.
D.The next level is made up of shorter plants with large leaves.
E.They give this area the richest species of plants and animals on the Earth.
F.Currently the Amazon rainforest emits around 1 billion tonnes of CO2 each year.
G.Over the past 50 years,about 17 per cent of the rainforest has disappeared due to human activities.
