We humans live in different parts of the world, but we have the same “mother”. She gives us everything we need in our daily life. She is our Mother Earth.
April 22 is Earth Day. The theme of this year is “Green Cities”.
A green city is a healthy and pleasant place for people to live, according to the United Nations.
A green city can get its energy from renewable (可再生的) sources like solar (太阳能的) and wind power. Also, it is connected by clean public transportation. Moreover, a green city is made up of facilities (设施) that can save energy and reduce waste.
Around the world, many cities and countries have done well to build themselves in a green way.
Chicago is well known for its green roof (屋顶) program. These roofs are covered with plants. The plants get a great amount of rainwater. Later, the water evaporates (蒸发) to help make the air cool and clean. So far, there are about 360 green roofs in Chicago, according to the US Environmental Protection Agency.
Curitiba, Brazil, has great transportation. It opened the world’s first bus rapid transit (BRT) system in 1974. BRT runs on special lanes. This makes sure that buses are on time even in traffic jams. With the help of BRT, the city has the lowest level of air pollution in Brazil. Today, many other countries have copied BRT, including China and Mexico.
Singapore is home to the first zero-energy building in Southeast Asia. Zero energy means a building is able to create more energy than it uses. Zero-energy buildings work with solar panels (板) mainly on roofs. These panels can make electricity which powers the buildings. By 2030, Singapore plans to build 80 percent of its buildings like this.The theme of Earth Day this year is “_______”.
| A．Green Roofs | B．Green Cities |

She gets up early in the morning，and then she talks with her family about the business over breakfast．Every day she goes to school in her own car with a driver，for she is not old enough．
She enjoys her school，but some of the work is too easy for her to feel interested．She usually gets“A”grades in all her subjects，so the other students often ask her for help．

Not many years ago，some farmers were worried because hawks were taking many of their chickens．The farmers didn’t know what to do．Finally they went to the country officials and asked for help．
“Kill the hawks，”the officials said．“We will even pay for them．”So the farmers began to think of ways to kill the hawks．
The farmers killed many hawks．They no longer had to worry about their chickens．But they now had a new worry．Field mice were eating up a lot of the farmers’grain．
How did this happen？
Hawks eat not only chickens but also field mice．They eat more field mice than chickens．But the farmers didn’t know this．When they killed a lot of hawks，they changed the balance．
When people move into a new place，they often destroy many wild plants．Often these plants are food for the animals．If the animals can’t find enough plants to eat，they will starve or have to leave the place．
In one part of the USA，for example，the deer there like to eat a certain kind of wild roses．The mountain lions there eat the deer．The number of deer，mountain lions and wild roses doesn’t change much if people leave things as they are．
But people killed many mountain lions in order to protect the deer．Soon there were so many deer that they ate up all the wild roses．Then the deer began to eat the green leaves of young trees．These trees were important to the farmers．So the farmers thought of ways to protect their trees．Now the deer had nothing to eat，and many of them died．This was another lesson from nature．
To keep the balance of nature is important for us to rememher．

There are many wetlands(湿地)in China and some of them have become the world’s important wetlands．The Chinese Yellow Sea Wetlands are among them．They are in Yancheng，Jiangsu Province．They are home for many different kinds of birds and animals．The world’s largest Milu Deer Nature Reserve(自然保护区)is in them．More than 700 milu deer live freely there．There are not many red-crowned cranes in the world，but every winter you can see some in the Red-crowned Cranes Nature Reserve in the Yellow Sea Wetlands．
The temperature in the wetlands is usually neither too high nor too low．There is a lot of rain and sunshine，too．They are really good places for wildlife(野生生物)．Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands．Wetlands are important because they also prevent flood．But some people want to change the wetlands to make more space for farms and buildings．This means there will be less and less space for wildlife．

A famous teacher was speaking to the students at our school．He began his lesson by holding up a ￥100 bill．Then he said to the three hundred students，“Who would like this ￥100 bill？”The students began to put up their hands at once．
Then he said，“I am going to give this ￥100 to one of you，but first，let me do this．”He then made the bill into a ball．Then he said，“Who wants it now？”The hands went back into the air．
“Well，”he said，“what if I do this？”and he dropped it on the floor and stepped on it．He picked up the dirty，crumpled bill and said，“Who still wants it？”Hands went back into the air．
