If you logged on to weibo over the weekend, you would notice the videos of US famous people getting wet through the ice water.
It seems everyone is getting in the fun, from popular singers like Taylor Swift to the richest businessmen including Bill Gates.
Is it some kind of new, cool way to fight against the summer heat? Of course not.
It’s a game of donation called the Ice Bucket Challenge, and it aims to raise money for amyotrophic lateral sclerosis (ALS).
The challenging game is easy. The person who takes the challenge should pour a bucket of ice water over their head within 24 hours, or donate money toward fighting ALS. Even if a person completes the challenge, they’re more than welcome to donate money anyhow.
Once a person completes the challenge, they’re supposed to issue the same challenge to several other people, usually three, which is why the challenge has been growing and growing.
Since the beginning of June, the game has spread across the US. According to Facebook, it has raised more than $2.3 million (14 million yuan) to support research for the illness.
The ice bucket challenge started with Pete Frates, a former captain of the Boston College baseball team. Frates, 29, who was diagnosed(诊断) with ALS in 2012, can no longer speak and uses a wheelchair. After Frates posted his own ice bucket challenges video on July 31, the game took off and has now become one of the hottest games in the world.

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．

Thanks to the hybrid rice that was discovered by Yuan Longping， the hunger problem of thousands of Chinese people was mostly fixed in the 1980s．
On Sept 8 th，Yuan， together with two other scientists，won China's 2018 Future Science Prize， for his continuous research on rice． Even on his 88th birthday on Sept 7 th，he took part in the International Development Forum of Rice Production in Hunan province． Although he was recovering from an illness at the time， he was happy to talk to reporters about his latest work on seawater rice．
Yuan has been researching on rice since he was at college． In 1964． he discovered a natural hybrid rice plant in Hainan． Since then， he has focused on developing high﹣yield， hybrid rice varieties
（多样性）．In 1973． he became the first to successfully cultivate（培育） a type of hybrid rice species in
the world．With the hard work of Yuan's group for about ten years， the production of the rice was increased．（From 150 kg per mu （亩） to 500 kg per mu and more． ）These varieties now take up about two thirds of China's rice crop， according to China News． So， it's no wonder that he's known as the "Father of Hybrid Rice"．
And because of China's Belt and Road （一带一路）initiative． Yuan's hybrid rice is helping to solve food problems around the world． Indeed， according to Xinhua News Agency， hybrid rice plants in Kenya produce four to five times more rice than the country's usual nice plants．
With a rising fame all over the world， Yuan gave a speech in English at the 9th Shandong High﹣Level Talents Forum in Qingdao last year． His speech made him an internet sensation．Beginning with"I speak broken English"， his 20﹣minute speech turned out to be a huge success，with barely any pauses or mistakes． The humble Yuan was simply being modest during his speech．According to an article in 1999 by CNN， the scientist speaks both English and Russian fluently． "I never need an interpreter when I go overseas，" he told the US news network．
But in spite of his great knowledge， Yuan understands that even the wisest people should still be open to learn new things． "The farmers of our country possess rich experience in planting rice，"he told Xinhua．" We should learn from them．"

Shanghai University of Engineering Science has become the first university in China to be covered by a 5G network，the university announced on Tuesday．
Chinese mobile carriers（运营商） are expected to spend 1.2 trillion yuan（US＄176.5 billion） on 5G by 2025，50 percent more than their total 4G investment （投资）， Nomura said yesterday． Carriers including China Mobile，China Telecom and China Unicom， are expected to build over 4.9 million 5G base stations by 2025．
5G is a"game﹣changing" opportunity for carriers as they can explore new business like smart manufacturing， super high definition video and smart driving， instead of just being a "pipeline" for voice and data services．
China will supply "temporary "5G licenses in several aimed cities this year． Consumers（消费者） will be able to use the first batch of 5G smart﹣phones and tablet computers in the second half．It's the first time that China's top industry regulator clarified the 5G industry timeline， especially the first appearance of 5G phones．
But 5G services will become accessibleto normal consumers later than expected． More work needs to be done to make the 5G industry fully developed， which won't happen until 2020， said UBS recently． New business projects and organizations， rather than normal consumers， will enjoy 5G services at first． The first batch of 5G services will be available to consumers in about 10 cities only．

Global warming is a big problem that we have to stop． One of the best things we do is to plant more trees． Trees can take in CO2 in the air and stop global warming．（1）
A team of scientists at Boston University has been working with NASA to study Earths green vegetation（植被）． They used a special NASA camera and found that global leaf area had increased by 5 percent since the early 2000s． （2） That's about one﹣quarter of the size of the entire Amazon rainforest．
The growth mainly came from China's forest protection programs， NASA said． For example， since 1962． China has been planting trees in Saihanba． Hebei Province． It was once a desert，（3）
（4） Ant Forest， a feature in Alipay app， gives users points for doing eco﹣friendly things such as walking and going paperless in the office． Users can then use these points to water and grow their own virtual（虚拟的）trees． When the virtual trees are big enough， Ant Forest will plant real trees somewhere in the world．（5）
A． More than 55 million trees have been planted in this way．
B． The Chinese public has also joined in these activities recently．
C． And China was responsible for 25% of that gain． according to the study．
D． However， people there can produce vegetables without any difficulty now．
E． But now， China has turned the area into the country's largest man﹣made forest．
F． According to a news report， China is doing a great job of"greening"the world．
| A If we laid all of the blood vessels（血管）in the human body end to end，they would reach about 100，000km long． That's nearly two and a half times around Earth! |
B For the first time， Coca﹣cola has showed that it uses 3，000，000 tons of plastic bottles each year． That 's the weight of 15，000 blue whales﹣ the largest animal on Earth． |
C If your throat tickles（发痒）， pressing your ear might make it go away． That's because your throat and ears share the same group of nerves（神经）． When you press your ear，the nerves in your throat can feel it． |
| D It takes about 7 to 8 trees to make enough O 2for one person to breathe for a year． Each person needs around 750 kg of O 2per year．A large tree might make around 100kg of O 2per year． |
E To young children． a year might seen to last forever． But older people might say that it flies by． Why is that？ According to the US scientists， young people's brains deal with information faster than older people． They take in more information and do more things in a day． So they feel like each day last longer． However， older people's brains take in less information and see a day pass more quickly． |
F About 200 muscles（肌肉）work together when you take a step． That 's a lot of work for your muscles， since many people take about 10，000 steps a day．If you want to get some easy exercise， walking is good for you． |
