Billy, Chris and Alice are talking about their ideas about a good friend.

Billy: I think a good friend should be honest (诚实的) . That's more important than any other things and is where a good friendship starts. If a friend isn't honest, he may lose his friends' trust (信任) .

Chris: I think a good friend has to be generous. Here "generous" doesn't mean (意味着) he has to give his friends his lunch money or his clothes. It means he should share his ideas and feelings with his friends. In fact his friends can know him better in this way.

Alice: In my opinion, a good friend should understand his friends. When there's something wrong between him and his friends, he must put himself in his friends' place and think more for his friends.

In December 2021, people in Shenzhen found that water ran more slowly from their taps. The government (政府) said the city was facing its most serious water shortage (短缺) ever. Compared with northern areas, southern areas have more rain and are close to more rivers and lakes. So why are they still "thirsty"?

In big cities like Shenzhen, populations (人口) are growing fast. As a result, people and factories need more and more water. Each person in Shenzhen has less than 200 cubic meters of water each year. It's 1/12 of the country's average.    

Climate change is making the water problem worse. For example, most cities in Guangdong depend on (依赖于) the Dongjiang River as their main source (来源) of water. In 2021, the river was reported to be drying up. Because of climate change, there's also less snow in the mountains of Tibet. The snow has long been the source of water for many areas in China. Those mountains might provide less water in the future.

There are other reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms don't use water efficiently (有效地). Some cities have enough rainfall, but don't have big lakes or reservoirs to store water. The water just goes into the sea.

I live in a  neighborhood. There is a post office between my house and a clothes store. I often go to the clothes store with my mom on . But my favorite place is the library. It is very quiet and I enjoy  there. When I read books, time  quickly. You can get to the library easily. Just go down North Road and turn left. It is  from the park.
