1 . In the past several months, Apple, Google and Samsung have all launched their newest smartphones and other products. But in the process, this may also be adding to a growing problem: electronic waste.
The limited lifespan of many tech gadgets(设备)has caused the issue of e-waste to increase over the years. “People tend not to realize that all these seemingly insignificant things have a lot of value, especially in large amounts, ”Pascal Leroy, director general of the WEEE Forum, said in a statement
How to solve the problems of e-waste is much more than just cleaning out space in your junk drawers. Actually, large amounts of e-waste are shipped to developing countries that lack the power to refuse and safely recycle these imports. The WHO warned that children, with their smaller hands, are often used to deal with mountains of e-waste in developing nations in search of valuable elements such as copper, silver, palladium and so on. The WHO said the health of more than 18 million children are being affected negatively as they are employed in this informal e-waste processing industry.
Personally, what can you do to reduce the e-waste burden? Find an e-waste disposal(处理) service. The impact of recycling e-waste can be staggering. For every 1 million cellphones that are recycled, 35, 000 pounds of copper, 772 pounds of silver, 75 pounds of gold and 33 pounds of palladium can be recovered. Meanwhile, environmental advocates say the most important step to deal with the mounting e-waste problem is simply to try to use your electronics for as long as possible

2 . Coral reefs(珊瑚礁)as underwater walls can help reduce the effects of hurricanes on coastal communities. This seems unbelievable. It is reported that scientists have discovered that coral reefs are even more effective than man-made sea walls under the water. However, coral reefs are especially easy to be influenced by climate change. Overfishing and pollution have also proved very dangerous to them. Since 1950, half of the world’s coral reefs have already been lost. To protect our communities and keep sea ecosystems alive, we need to protect coral reefs right away.
Let’s take a closer look at how coral reefs protect us from floods, and how scientists are restoring (修复) reefs.
The roles that coral reefs play as underwater walls have long been recorded by scientists. During a Category 3 hurricane in 2015 in Australia, the coral reefs effectively protected the eastern shoreline from flooding. In contrast, the western coasts without coral reefs suffered serious damage. The researchers observed that the shape of coral reefs can break the approaching waves. More recently, researchers at the University of Miami have reached the same conclusion. They used a special lab simulator to recreate ocean conditions during a Category 5 hurricane. They found that coral reefs could reduce the impact of waves by up to 95 percent!
Because of higher ocean acidity (酸 性) and temperature, coral reefs are disappearing and dying out. At the same time, climate change puts weakened coral reefs under more stress. The University of Miami researchers are testing to plant new coral reefs while others are actively looking for effective methods to reduce the acidity of sea water. The governments have also paid more attention to these actions and provided enough money for reef restoration. With these efforts, we may address climate threats to coral reefs and they can carry on protecting our communities.

3 . Going green is good for business. Consumers are often willing to pay more for eco-friendly products than other comparable products on the market. But not all environmental claims are created equally. “Greenwashing” is a form of misinformation often used to entice a green consumer. Companies promising to be environmentally conscious sometimes fail to meet the promises they make to consumers.
For example, a large retailer might launch a new line of products, such as jeans, that uses less water and therefore theoretically has less of an environmental impact than the other clothes the company sells. But that same company might ignore water usage in the rest of their products lines or do nothing to address their other products that might be harming the environment.
Is it possible to avoid falling victim to greenwashing? Learning about greenwashing and how it works is the most effective way for consumers to avoid giving their money to companies making false claims, according to a recent study. The researchers found people who received information on greenwashing ahead of time were more likely to question whether what the company did in fact benefited the environment.
In the meantime, experts have tips for how consumers can spot potential greenwashing. “You see a lot of products that use words like ‘sustainable’, and ‘better for the planet’ with pictures that make it look like it’s green,” says Todd Larsen, the director of Green America, a nonprofit aimed at helping consumers identify greenwashing. He recommends looking for descriptions that outline specifically how a product is green.
Another tip he offers is to shop small. “When in doubt, go smaller,” says Larsen. “Rethink shopping habits. The most sustainable thing you can do as a consumer is wear the things you have more.”

| B．People are getting fed up with greenwashing. |

4 . Having lived in California until 1970, my family has felt a number of earthquakes. We have been fortunate, however, to have suffered no bodily harm or property damage.
There is a website that lists all Californian earthquakes recorded from 1769 to the present. The site lists the dates and time as well as the magnitude (震级) and the exact location of any earthquake that measured more than 6.0. There are only a few earthquakes that stand out in my memory and, luckily, none is shown in the website. So, my personal experience with earthquakes might be considered insignificant.
There are three earthquakes that are difficult to forget. The first one was in 1955 and our oldest daughter was walking with me in our backyard in Redwood City in California. As the shaking became stronger, I held her to me with one arm as I held on to one of our fruit trees with the other. All three of us (my daughter, I and the tree) shook for two or three minutes that to us felt like hours.
The second one was in 1963. Our entire family was visiting Disneyland in Southern California. The earth started to shake just as we were beginning to walk from our hotel towards the famous landmark.
My third experience with an earthquake was a lonely one in California. It was in my sixties and I was alone in an old church. As the building started to shake, I quickly headed for the door to go outside. I remember I said a few prayers—something like “Help me get out of here in time, dear Heavenly Father.” Minutes later, I was safe outside.
