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．

A． A green roof is alive．
B． A green roof stops pollution．
C． A common roof is noisy．

Why do we need to throw less away? There are two reasons. One is that some resources（资源）are nonrenewable（不可再生的）. That means there is only a certain amount of that resource in the world. One example of these resources is oil. When we use up all the oil in the world, there will be no more.
There is a second reason for throwing less away. All of our trash has to be put somewhere. Often, it is put into garbage dumps（垃圾场）. Much of that trash will be there for hundreds of years. The dumps ill be filled up with all this trash.
There are three ways to cut down on trash.
One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspapers may become paper bags. A glassware can be melted（熔化）and made into a bottle.
Another way to cut down on trash is to reuse things. You can wash and use a bottle again that can hold mustard（芥末酱）or something else.
The third way to cut down on trash is to reduce the amount of trash you make, for example, stopping buying things that you don’t need in the first place. That reduces the amount of the earth’s resources.

I can’t remember when I started collecting litter（垃圾）. But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.
I live close to a forest in Ohio, America. I can walk there in three minutes! I used to love going there to play with my dog. But one day there was so much litter there that I became very unhappy. I decided to clean up the forest. I wanted to feel happy going there again.
I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was full! It had cans, bottles, broken glass and newspapers in it.
Since that first trip three years ago, I’ve gone to the forest four times a year to pick up litter. I’m often there for three hours. It makes me feel great to do something for the environment.
After each trip, I look at all the litter I’ve found. If any of it is recyclable（可回收的）, I keep it. I can’t understand why people drop litter. But I will keep picking it up until they stop dropping it.
I know I can only do a small bit to help the earth, but I still think it is important.．When did the writer begin to collect litter?
