Let's say you are taking a walk along the road and you happen to see one or two waste bottles lying on the grass beside the road． What would you do？
You may have different choices． Firstly ，you can leave the bottles there as they are． It was not you who threw them away． Why should you do something about it？ This is quite OK． Secondly， you can pick them up and throw them into a dustbin （垃圾箱）． By doing this，you have walked a step further to help make our homeclean． This action is a better choice． Thirdly， you might want to pick them up and give them to an old man or woman who collects waste for a living． If this is your choice， you have walked even further． You're not only thinking about doing something for the environment， you're also developing yourself to be a person who would think of others and help them．
As for young kids， they may always have such a question："When do I grow up？"Yes! When does a child grow up？ And how can a kid know he or she has grown up？These are interesting questions．As for us，fifteen﹣year﹣olds，who are finishing middle school， we're no longer younger children．We should know whether or not we have grown up． When we start to have a sense of offering a helping hand for a cleaner city and greener world， and when we have a loving heart to think more of others than of ourselves and are ready to help them， we can say that we have grown up．
Remember： If we help others， others will help us． If we do our best for nature， nature will offer its best to us in return !

阅读下面材料，然后从各题所给的四个选项中选出一个最佳答案．
Fresh green grass． Hundreds of colorful wild flowers． Water running into little pools． Birds making their homes in boxes． The 9， 500﹣square﹣metre Augustenborg Botanical Garden may look just like any other well﹣organized park but there's a difference． It lies on the roofs（屋顶） of industria land office buildings in the city of Malmo in Sweden．
Green roofs are not a new invention． And now they are getting popular again． The common roofs of a modern city have endless black surfaces with no life or water． Perhaps that's why a garden on a roof becomes such a perfect choice for more and more people．
Green roofs are not just pretty． They also help to moderate the city temperature． The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot． What is more， they play a part in making the cities hotter than the countryside around them， causing the "urban heat﹣island effect"． On a green roof， however， with its plants and water， temperatures change only a little， as they do in a park． This can greatly cut the costs of heating and cooling in the building below．
Also， a green roof takes in rain water， and protects the city drainage（排水） system．_____ And small animals and birds can make their homes on it． Thanks to this， the city may become part of nature， rather than something completely separate from it．
While the cost of building such a roof can still be higher， it can be cheaper in the long term as a result of energy savings． And wouldn't it be wonderful to be able to walk out into a garden high above the city's noise and traffic， whether you're at school or in an office or just at home in a ten﹣floor block．
（1）With the example of Augustenborg Botanical Garden， the writer wants to explain ．
A． how wildlife is protected
B． what a green roof is like
C． how to organize a good park
D． what to do with a spare roof
（2）The underlined word " moderate" in Paragraph 3 is the closest in meaning to " "．
A． raise

A． A green roof is alive．
B． A green roof stops pollution．
C． A common roof is noisy．
D． A common roof increases the cost．
（4）The purpose of the passage is to ．
A． discover the problems with green roofs
B． introduce the change of green roofs
C． show the amazing beauty of green roofs
D． describe the advantages of green roofs
Cycads（苏铁）grow in warm places．They are tall and green all year round．Their leaves grow on the top and flowers seldom come out．Some have bright orange fruits．They usually need hundreds of years to grow into adult plants．
Cycads are facing problems now．In South Africa，the situation of cycads is getting terrible，but this has drawn little attention from the public．"In fact，there are 38 kinds of cycads in South Africa．Among them，2 kinds have disappeared since 2003 and 25 kinds are in great danger，"said a gardener．"Do you know what the loneliest plant is in the world？It is Wood's Cycad．Someone found it in a forest in 1895．It is the only one of its kind．"
So what causes cycads to be in danger？Surprisingly，the danger is from the people who love them most． These slow﹣growing adult cycads even sell for tens of thousands of dollars each．As time goes by，they have become a symbol（象征）of wealth and position（ 地位）in society．This makes cycad lovers want to own more． Cycad lovers buy and plant them in their private gardens．As a result，nearly all these cycads die because the living conditions have changed．
Recently，South African government has taken some actions to protect cycads from being stolen traded．At the same time，people around the world should also work together to protect the plants．
（1）The flowers of Cycads come out once a year．
（2）The cycad lovers cause cycads to be in danger．
（3）The Wood's Cycad found in 1895 is the only one of its kind．
（4）Cycads have become a symbol of luck and health．
（5）The writer expects people to join together to save the plants．

It was dark outside the car window that it was hard to see anything．
"Can I have a carrot，Mum？"Riley asked．
"I don't have any carrots，"her mum said．"If I eat one now，it might help me see in the dark．"
Would eating a carrot really help Riley？What is special about carrots？A clueto what makes a carrot special is its color．Carrots are orange because they store beta﹣carotene（β胡萝素）．Beta﹣carotene is a way to talk about vitamin A （维生素A）．Your eyes need vitamin A．It helps them work．
When light hits your eyes，very small parts inside turn the light into messages．The messages go to your brain（脑），and then you know what you're looking at．Your eyes can only turn light into messages when it has a special chemical（化学物质），that's where vitamin A comes in．Your eyes use vitamin A to make the special chemical．Every time your eyes change light into messages，a little bit of the chemical is used up．By the end of the day，you're looked at hundreds of things．That uses up a lot of the chemical．Your eyes need to make more．
What should you eat if you don't like carrots？Don't worry．Other fruits and vegetables have vitamin A，too．The secret is in their color．Most orange or red fruits store some beta﹣carotene，or vitamin A．Sweet potatoes，red peppers，mangoes（芒果） are a few that have the same orange secret．Can you think of any more？

The world has a plastics problem． And not just with bottles． Straws（吸管）， toothbrushes， toys﹣all kinds of plastics are placed in landfills． There are 5 billion tons of plastic waste in the world． Landfills have a large part of it． By 2050， they could have 13 billion tons．
Much of plastic rubbish finds its way into the ocean． Scientists say 165 million tons of plastic pieces are floating around out there． And most plastic won't disappear itself． It will remain in the ocean forever． Whales get caught in plastic fishing nets． Birds die because of eating plastic straws and bottle caps． It endangers ocean life． Plastic rubbish even ends up in the food we eat．
Governments are realizing that recycling may not be enough． They are taking more actions． Though it is hard work， it is still a solvable problem． In Britain， people are not allowed to use plastic bags except in hospitals． Scotland and several coastal cities in the US stop people from using plastic straws as well． The US alone throws away some 500 million plastic straws a day． That's enough to circle the Earth twice． "Saying no to a plastic straw is an easy way to make a big difference，" Dana Lofflin who started said． "Do we really want to pass on to our children a world harmed by plastic？"
People have found some tasty ways to reduce waste． A company in India made the first﹣ever spoon that people can eat． You don't have to eat the spoon． You can throw it away． It decomposes（分解） in just a few days． David Edwards， a scientist at Harvard University， designed an eatable bag which can protect the food or drink inside． It is a delicious replacement for plastic ones．

Trees are one of the oldest" citizens（公民）" of our Earth． They keep our air clean ， reduce noise pollution， improve water quality and provide food and building materials．
Just like us， trees change a lot as they grow． At I to 3 years old， young trees learn how to protect themselves． For example， many trees grow thorns（刺）to warn animals not to go near． Most young tree have large， deep green leaves so that they can catch enough sunlight and change it into their food and energy．

Energy is everywhere in the world．We use energy every day．There are all kinds of energies in the world，such as hydropower resources，sun's energy，wind power．
Liangshan is called"kingdom of hydropower resources"．Jinsha River，Yalong River and Dadu River are just like three great dragons carrying hydropower resources to Liangshan from the
Qinghai﹣Tibet Plateau．The government has planned to build 11large and super hydropower stations on Jinsha River，Yalong River and Dadu River within Liangshan．On the other hand，there is rich wind power in Liangshan．The government is building a large wind power station between Huili and Ningnan．
Electricity is a form of energy，and this is what powers the TV，mobile phone，fridge and more．Our growing need for energy is one of the problems in the world today，because producing electricity also produces pollution．Although energy in Liangshan is very rich，we must do something to protect the environment and save lots of energy．
