Many environmental groups are warning that oceans of the world are in great danger. In the past 50 years, the number of water with zero oxygen(氧气) in the open ocean has increased more than four times. In the near coast water bodies, including the river mouth and seas, low-oxygen areas have increased more than 10 times since 1950.Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms. To stop the drop, the world needs to control in both climate change and nutrient(养分) pollution.

    Oxygen is a must to life in the oceans. The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment.

    This is the first time for the scientists to take such a deep look at the causes, results and solutions to low oxygen worldwide, in both the open ocean and the near coast waters. About half of the oxygen on Earth comes from the ocean. However, mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters, where oxygen is too low to support most sea life.

    In the areas traditionally called "dead zones", like those in Chesapeake Bay and the Gulf of Mexico, oxygen drops to levels so low that many animals have trouble in breathing and die. As fishes run away from these zones, their living areas become smaller and smaller. But the problem goes far beyond "dead zones". Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death. Low oxygen also can cause the release of dangerous chemicals. Although a few animals can grow well in dead zones, overall biodiversity(多样性)falls.

What will life in the future be like? And what will we be able to do in the future? 

Genetic engineering (基因工程) may help us make the perfect human. Babies may grow up to play basketball like Yao Ming. Also, we may be able to bring the dead back to life. Maybe people will be able to meet and talk with their dead family members. 

Over the next 20 to 50 years, it will become harder to tell (分辨) if a person is dead or alive. Perhaps humans will be able to make copies of ourselves, so we will appear to be alive long after we are dead. Humans may be able to find ways of putting the life of a person into a new body. 

Nanobots (纳米机器人) will be important. We will use them when we are sick. For example, when we have a stomachache, we will swallow (吞下) a nanobot and it will tell the doctor what's happening in our stomachs by taking a video with its camera. 

In the future, computers may have feelings. They may be able to think better than us. We may be more and more interested in computers and spend all our time in front of computers. Perhaps we will forget our real needs. Perhaps we will weigh 250 kgs!

My Perfect Neighborhood

I'm Helen. I live in a perfect neighborhood. The street is very quiet. Some people like lots of noise and crowds, but I like quiet places. My house is between a big park and an apartment building. On the weekend, I sometimes buy a magazine(杂志) from the newsstand and sit in the park to read it. There is a big supermarket not too far away. Next to the supermarket is a small basketball court.

Across the street is a bakery(面包店), and next to the bakery is a cinema where I can watch interesting movies. So, you see, my neighborhood has everything I need. The only thing that isn't so nice is it's far from my school. In fact, I need to take two buses to get to school.

A highly expected video game based on classic Chinese novel came out worldwide on Aug20,making gamers around the world excited.

The game, Black Myth(黑神话）:Wukong,was inspired by the rich Chinese folk(民间） stories and the 16th-century novel Journey to the West(西游记）,one of the four great classic novels of China.

＂To create a fascinating Chinese story, we also looked to many Chinese classics, taking ideas from their stories,characters and monsters, such as The Classic of Mountains and Seas(《山海经》）and The investiture of the Gods(《封神演义》）. They all inspired the making of the game,"creator Feng Ji said.

In the game, players will step into the shoes of the iconic Sun Wukong, also known as the Monkey King,and travel to different places, from green forests to dark caves. During the journey, players use Wukong's powerful stick and ability to solve problems and beat special enemies.

It is China's first 3A game, meaning it has high-quality graphics(画面），a rich story,and exciting fighting.The game's production team traveled across China and scanned ancient buildings and relics(遗迹).It put the creations and historical relics into every scene of the game. What's more, the game uses traditional Chinese instruments such as the guzheng, bowls,wooden clappers and gongs. Much of the music is made using Chinese-style chord(和弦）。

 This game is a great example of the talent and creativity of Chinese game developers. As the game continues to gain popularity, it is expected to further spread Chinese culture and help Chinese game stand on the global stage.
