1 . Steven Stein likes to track garbage trucks. He says, “It’s hard to resist.” Stein’s strange habit makes sense when you consider that he’s an environmental scientist who studies how to reduce litter, including stuff that falls off garbage trucks as they run down the road. What is even more interesting is that one of Stein’s current plans is defending an industry behind a source of trash: plastic shopping bags.
Americans use more than 100 million plastic bags every year. So many end up in tree branches or along highways that a growing number of cities are banishing (排除) them from checkout lines. The bags are outlawed in some places in the USA.
Facing these situations, plastic-bag manufacturers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume. “It’s important to base your decisions on facts,” says Stan Bikulege, CEO of Hilex Poly, which has hired Stein.
Among the bag makers’ argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.
The industry has also taken aim at the product that can take the place of plastic bags: reusable shopping bags. The sturdier a reusable bag is, the longer its life and the more plastic-bag use it cancels out. But this plan has another side. Longer-lasting reusable bags often require more energy to make.
Environmentalists don’t agree with these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years. So are reusables our destiny? The answer is probably yes. And Andy Keller, inventor of reusable polyester (聚酯纤维) bags, says, ”If you can carry it out in your hands or put it back in your car, you don’t need a bag.”

2 . A major new facility to pull CO2 out of the atmosphere has started operating in Iceland, which is a boost to an emerging technology that experts say could eventually play an important role in reducing greenhouse gases.
The plant in southwest Iceland is the biggest of its kind, its builder says. It is able to capture 900 tons of CO2 every year but it needs heat and electricity to work. It is using energy produced from waste and is built on the roof of a waste incineration plant, and through the burning of rubbish, energy is generated.
Human-sized fans are built into a series of boxes. They take CO2 out of the air, catching it in spongelike filters (过滤器). The filters are blasted with heat, freeing the gas, which is then mixed with water and pumped deep into deep underground basalt caves, where over time it turns into dark-gray stone. Pumping CO2 into the ground is just one way to deal with it. The makers are also selling the gas to be used again. The CO2 can be captured just a few 100 miles away. It is pumped through an underground pipeline directly into a greenhouse. Vegetables and plants love CO2 and higher concentrations of the gas within the greenhouse improve the growth of plants.
By 2050, humanity will need to pull nearly a billion metric tons of CO2 from the atmosphere every year through direct air capture technology to achieve carbon neutral goals, according to International Energy Agency recommendations. The plant in Iceland will be able to capture 4000 metric tons annually — just a small amount of what will be necessary, but an engineer in Climeworks, the company that built it, says it can grow rapidly as efficiency improves and costs decrease.
“This is a market that does not yet exist, but a market that urgently needs to be built,” said Christoph Gebald who co-founded Climeworks. “This plant that we have here is really the blueprint to further increase the size and really industrialize.”

3 . Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(缺乏). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks(滴水) in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
1. Which of the following is most likely to lead to less groundwater?| A．Using river water. | B．Throwing batteries away. |
| C．Throwing rubbish into lakes. | D．Paving parking lots. |
| A．All water shortages are due to human behavior. |
| B．It takes a lot of effort to meet our water needs. |
| C．There is much we can do to reduce family size. |

| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
| A．how human activity affects our water supply |
| B．how much we depend on water to live |
| C．why droughts occur more in dry climates |
| D．why paving roads reduces our water |
4 . In the United States, most of our electricity comes from power plants (发电厂) that burn coal and oil.
There are two big problems with using these things for electricity. First, their supply is limited (有限的). Second, burning them causes pollution. So to make sure we always have power and to keep our planet clean, we must find other ways to make electricity.
Some people think that wind power is our best choice. First, there will always be more wind. Also, wind power does not pollute the environment. Best of all, we don’t have to search for wind.
Today, less than 1 percent of our electricity comes from wind. But scientists have been developing better wind machines. As a result, wind power is getting more popular in this country.
Yet wind power may not keep growing so quickly in years to come. Why not? Many wind turbines (风力涡轮机) are needed to make much electricity. So wind-power companies try to build wind farms but are competing (竞争) with other uses for the land. A wind farm is a group of turbines placed close together in an area with frequent winds.
In places where companies try to build wind farms, people think that lines of turbines are ugly. Noise from turbines often troubles people. Also, turbines kill birds that fly into them.
Wind-power supporters disagree. They think the sight of wind turbines is lovely. They point out that people have gotten used to living near noisy highways. They say ways can be found to keep birds away from turbines.
In today’s world, we need clean and unlimited power sources more than ever. Unless a better power source comes along, people may just have to accept wind power as a part of their lives.

5 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf. as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports, Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements (代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

6 . Earthquakes strike suddenly at any time of the day or night, but there's no way to tell when. If an earthquake happens, it may cause many deaths, injuries and damage. So you need a good preparation ahead of time. Decide how and where your family will get together if separated. Choose an out-of-state friend or relative that the family members can call after the quake to report where they are and how they are. Know the safe places in each room: under the strong tables, desks, or against inside walls. Keep enough food, water and other things, including a flashlight, a radio, medicines and clothing.
During the earthquake, you should keep a clear head and never be too nervous to know what to do. Protect your head and neck with your arms. If possible, take a book, a pillow or any other things to protect yourself from falling glass and ruins. If you are indoors, you must immediately lie under any strong furniture. If outdoors, move to an open area away from trees, buildings, walls or power-poles. If you are in a narrow valley, move to the centre of it and look up for falling stones. If you are in a car, move to the side of the road and stop the car. Do not stop near buildings, power lines or on or under bridges. Stay in your car until the shaking stops.
Do not move a badly injured person unless he is in great danger after the earthquake. Do not use the telephone immediately unless there is a serious injury or fire. Turn on your radio for instructions and news reports. Be prepared for aftershocks. If you want to leave your home, post a message inside your home telling your family members where you can be found.

7 . Pre-school children who spend time together take on one another's personalities, a new research has found. The study shows that environment plays a key role in shaping people's personalities. While genetics still forms the central part of the human psyche (心理), the research finds that personality traits (特征) are "contagious" (传染的) among children. "Our finding flies in the face of common assumptions that personality can't be changed," said Dr. Jennifer Neal, co-author of the study.
The researchers studied the personalities and social networks of two pre-school classes for a full school year. One of the classes was a set of three-year-olds, and the other a set of four-year-olds. Children whose friends were hard-working or outgoing gradually took on these personality traits over time. Psychology expert Dr. Emily Dublin said kids are having a far bigger effect on each other than people may realize.
The new study is not the first to explore the contagious effects of personality traits. A 2015 psychology study found that rudeness at work can be contagious as it travels from person to person "like a disease". The study found that seeing a boss being rude to an employee was enough to cause people to be rude to those around them.
The researchers questioned 6,000 people on the social "climate" in their workplaces, which included offices, hotels and restaurants. They found 75 percent of those who took part said they had been treated rudely at least once in the past year. And the study also suggests that merely seeing other people being subjected to rudeness made it more likely that a person would treat their colleagues in the same way. Rudeness could include leaving someone off an invite to a company event, sending unkind emails, finding fault with others or failing to give praise.
Dr. Torkelson believes companies need to be more aware of the harm that rudeness in the workplace can do as it can damage the working environment. She said better training could help to fight against the problem.

8 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.

10 . Climbers at Qomolangma are being asked to clean up after themselves.
Qomolangma has earned the nickname (绰号) the World’s Highest Garbage Dump (垃圾场).
Climbing Qomolangma, the world's highest mountain, just becomes more challenging.
The government of Nepal is telling climbers they cannot leave trash on the trails. Each climber will have to come down the mountain with at the least 18 pounds of garbage. That's the average amount of trash a climber leaves behind on Qomolangma.
Officials say climbers are responsible for their own trash. “We are not asking climbers to pick up trash left by someone else,” said the Nepal Tourism Ministry. “We just want them to bring back what they took up.”
More than 4,000 people have reached the 29,035-foot summit (顶峰) in the past 60 years. Leaving trash along the way helps climbers keep their bags light so they have energy to reach the summit. “The trash problem in Qomolangma is not new.” Burlakoti says. “When the people started to climb the mountain, they started to leave their garbage there.” They have left behind bottles, food boxes and equipment. Last year, climbers carried down a total of four tons of trash.
The new rule came into effect in April, 2014. To make sure it is followed, climbers will have to deposit money (交保证金) before they climb. Once they climb back down the mountain, officials will check climbers at a return camp to make sure they have the required 18 pounds of trash. If they do, their money will be returned to them. If they do not, climbers will not receive their deposit and they will not be given a permit the next time they want to climb Qomolangma.
The goal is to make sure no more litter will be left on Qomolangma. “As we offer Qomolangma to all the people of the world they should take responsibility to clean it.” Burlakoti says, “After seeing the results from this, we will also apply this rule to other mountains.”
