Environmental pollution kills 1.7 million children under the age of five every year worldwide. This is according to the World Health Organization (WHO). The WHO warns that child deaths will increase greatly if pollution continues to worsen.
The most common causes of death among children aged one month to five years are diarrhea, malaria and pneumonia. This is according to the WHO. 1. . This means providing access to safe water and sanitation, limiting exposure to dangerous chemicals, and improving waste management.
2.The WHO estimates that air pollution is responsible for about 6.5 million premature, or early deaths every year. That number includes nearly 600,000 deaths of children under age five. Most of these deaths take place in developing countries.
Air pollution is a leveler between rich and poor, according to WHO environment and health chief Maria Neira. 3.And one of the most important ways to reduce air pollution is to produce cleaner fuels for cooking and heating. “Almost half of the world population is using dirty fuels for cooking, heating, and lighting at home. And, this is affecting very much mothers who are staying and cooking at home, but the children who are around mothers -- they are exposed as well. ” Early exposure to harmful pollutants can lead to increased risk of chronic respiratory disease, asthma, heart disease, stroke and cancer later in life.
Cleaning up how the world cooks, heats and lights homes and other buildings is a big- picture goal. The WHO is advising government departments and industries such as construction and the health sector to work together to clean up their environment.
4.. The U. S. Environmental Protection Agency has the following suggestions：
• Avoid walking where there is a high volume of vehicle traffic.
•5.
• Limit your time outside if you live in an area that issues warnings about air quality.
• Wear high-grade, rated face masks tightly to the face when air quality is poor.
• Remove your clothes and wash immediately after entering your house if you live or commute in a very polluted area.
A. However, of all the environmental pollutants, air pollution is being called the most dangerous.
B. But what can individuals do to limit our family's exposure to air pollution?
C. Therefore, the WHO stresses that governments around the world need to take the lead on ensuring that children grow up in a clean environment.
D. The organization also says reducing environmental risks can prevent such deaths.
E. A polluted environment is a deadly one—particularly for young children.
F. Everybody, she says, needs to breathe.
G. Equip homes with air filters and air conditioning units.
Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.
“5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need high speed.
Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.
Ericsson stated at February’s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.
But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.

Rumors (谣言): we've all heard some and we've all spread some. In more traditional times they shook entire families. Today, they travel differently because the way we share information has also changed.
The fact is that rumors have great potential to upset things, whether socially or personally. We don't enjoy being on the receiving end of one, since they usually don't have good intentions. They are somewhat veiled (掩饰的) messages.
Normally rumors are oral messages: word of mouth. The paradox (自相矛盾) is that there is no evidence to support rumors, but the more people share it, the more they see it as true. To finish explaining rumors, we think that they follow certain very clear laws. Secrecy: The source is unknown. There is also a proven phenomenon that human beings usually forget the source of a message before they forget its content. Certainty: We hardly question rumors simply because of the mental effort involved. On the other hand, no one likes to doubt a person who convinces us that the information they spread is true. Change: It acts like a tree. New rumors branch out to fill in the gaps left by the first rumor.
Another property (属性) of rumors is that they tend to become viral. Each receiver is at the same time a potential transmitter (传输者) of the information. The receiver often adds their own opinion. Their manner and tone of transmitting it also changes it.
How can we end rumors? The answer is as simple as it is impossible: preventing people from communicating. A more realistic response is equally difficult, although less than the first one. It is that we should be critical of the information we receive. We should ask ourselves if the source is reliable. Ask (if possible) the person you heard it from whether they also trust the information. We should also think about if the rumor benefits someone, and if that someone started the rumor.
One rumor to be especially cautious of is a rumor about groups relatively unable to defend themselves. That's why we say, "History is always told by the winners." The first payment the defeated must make is to accept the victor's version of the story.
1.What can we learn about rumors?
A.We have all heard some and believed them.
B.We're happy to be the receiving end of them.
C.They may have negative influence on society.
D.They often hide good intentions in the messages.
2.How are rumours like a tree?
A.Rumours keep changing, just as trees change their colour.
B.Rumours are deeply rooted in reality, like tree roots in the earth.
C.New rumours have gaps, like the space between tree branches.
D.New rumours grow out of the original, like branches out of a trunk.
3.What does the underlined word ‘viral’ in Para 4 probably mean?
A.Something easily spread.
B.Something acceptable.
C.Something easily defended.
D.Something beneficial.
4.Which of the following may the author agree with?
A.It is easy to prevent people from spreading rumors.
B.People are often active in judging the rumors critically.
C.We should think about the hidden message of the rumors.
D.Stories told by the victors are usually better worth trusting.
Robots have taken over many of America’s factories. But can they pick a strawberry? “It’s really hard for robots to match what humans can do,” says Bob Pizter, an expert on robots.
Any 4-year-old kid can pick a strawberry, but machines can’t seem to figure it out. Pizter says the hardest thing for them is finding the fruit. Pizter’s strawberry-picking robot is rolling into a strawberry field. This well-designed device drives itself. It’s as big as a bus, long enough to straddle (跨越) a dozen rows of strawberries at once. Powerful computers are sitting on top. Underneath, there are high-definition cameras to find the berries, and robotic claws ready to pick them.
“Nobody’s telling it what to do,” explains Paul Bissett, the chief operating officer of Harvest CROO Robotics. “It’s remembering its path down the row. It’s remembering where all these plants are.” It knows all this, thanks to the super-accurate GPS. Its computer brain contains a map showing the locations of every strawberry plant in the field. The action of machinery is truly impressive, but the baskets are still practically empty. Pitzer says the robots are able to find and pick more than 50 percent of ripe berries. That’s not yet up to human standards. A typical worker, he says, manages to pick anywhere from 60 to 90 percent of the berries. Also, he admits, the machine is slower than human hands. On the other hand, it has some advantages. It can work right through the night. Two years later, he says, this machine will be in the fields working for real. “There are weaknesses to work out, but it’s getting there. We’re close.” he says.
Strawberry companies are putting millions of dollars into this project. The reason, Gary Wishnatzki, the owner of Wish Farms says, is that it’s getting more and more difficult to find enough people to pick his berries. “The fact of the matter is, if we don’t solve the problem of this labor shortage with automation, the industry is facing a big challenge ahead. The price of fruit is going to be much higher,” Jose Santos, the leader of the farm, says.
Jose is pretty convinced, though, that picking strawberries will always require people. The machines will break down, he points out. In fact, he’s looking on the bright side. “You could afford to give people a day off if you have machines behind you,” he says.
