1 . How many plastic carrier bags have you got in your house? I seem to have cupboards full of them and it feels like they’re taking over my home! The shopping bag is just one example of the milion things we use made from this useful material, plastic. But unfortunately, it’s not the easiest thing to recycle and this is causing an environmental problem.

Most of our everyday plastic items end up in landfill, left to rot away for many years. But some of it blows away, causing damage to the natural environment and harming wildlife. The problem is most serious in our oceans.

The study, published in the journal Proceedings of the National Academy of Sciences, described how remote islands act as a “sink” for the world’s rubbish. They become collecting points for fishing items and everyday things including toothbrushes, cigarette lighters and razors (剃须刀); things that we throw away. Dr Jennifer Lavers from the University of Tasmania says, “Almost every island in the world and almost every species in the ocean is now being shown to be impacted one way or another by our waste.”

This highlights the potentially deadly effect of our disposable culture. When we throw something away, it doesn’t just disappear, it goes somewhere and because of the long-lasting nature of plastic, it takes a lot time to decompose (分解) and stays there causing great damage to the ocean’s ecology.

Some other recent worldwide research estimates that 90% of all seabirds have swallowed plastic. And worse still, this plastic is broken down into tiny particles (颗粒) over a long period by the wind and the waves, then sea creatures at the bottom of the food chain ingest (咽下) them. These creatures are eaten by the fish that we eventually consume.

The solution to this problem would be to use less plastic. So next time you pick up a carrier bag, or buy a plastic bottle of water, spare a thought for the birds and animals on the remote islands. What do you do to help the environment?

6 . How to Survive a Lightning Strike?

According to the National Weather Service, almost two-thirds of lightning accidents occur as people enjoy leisure activities outdoors.     1    . Here’s how to stay safe when you’re enjoying summer outdoors.

Keep an eye on the sky

    2    . Thunderstorms usually occur in the afternoon or evening. Start your hike in the morning, and finish up by noon if the forecast indicates bad weather ahead. If the forecast calls for periodic storms throughout the day, make a smart choice and consider giving up the trip.     3    .

Before you head out for hiking, check maps to locate visitor centers, campground buildings, or rest areas along your route. Once you hear thunder, see lightning, or sense that a storm is approaching, don’t hesistate to use your plan. Hikers are strongly advised to watch continually for the nearest shelter.     4     .

Know the storm’s distance

Count the seconds between the flash and the following sound of thunder. Divide the number of seconds by five to calculate the number of miles between you and the storm. For example, if the number of seconds is 30, then the distance inbetween equals six miles, and find shelter immediately.     5    , just remember that you can hear thunder at a distance of 10 miles.

7 . Recycling is good for our planet, but it can be confusing. Can I recycle plastic bags? What about pizza cartons? Toothpaste tubes? Which bin should I use? There are so many questions, and more than half of Americans are unsure about how to recycle.     1     Here’s a handy four-step guide on how to recycle effectively:

Know what to put in the recycling bin. Keep it simple and focus on the most commonly recycled items, such as paper, glass, aluminum and plastic.     2     Don’t use the recycled symbol as a guide. “The number on the container is really for people to identify the type of resin (树脂). That’s not helpful for the common consumer,” said Cody Marshall, a strategist at nonprofit Recycling Partnership.

    3     It is really important to know what you cannot put in your bin. You can always check with your city or at BeRecycled.org. If you live in the US, just plug in your postcode to search. Recycling companies struggle with the same problem items: hoses (软管), cords, needles and clothing, according to Marshall, so don’t put those items in your bin.

Wash or clean items. Do a quick clean to make sure there is no food left in containers before you put them in the bin.     4     Save food for composting (堆肥) in your garden.

Don’t bag it. Unless you live in a place that requires it, like New York City, keep the recyclables lost in the bin. “A lot of the time, it’s not safe for our employees to tear those bags open, or it takes too much time,” said Keller. “    5    ”

Floods and landslides are hard     1     (avoid). However, to protect against them, people take a variety of measures. These could include passing various     2     (law)that prohibit(禁止) cutting down trees and building houses in these areas. Measures can     3     (take)at all levels so that no one is misusing or overusing their share of resources like water and food.

Areas     4     strong winds and tornadoes frequently happen need different precautionary(预防的) measures. Tornadoes and storms can be predicted(预测) to a degree in today’s world. Once one is predicted,     5     is important not to walk out without reason. Asking the kids to stay at home is another good measure. These areas usually have     6     (strong)built houses not to be damaged by extreme conditions. However, having a basement where you can stay and wait for the storm to pass     7     (be)not a bad idea. Make sure that the basement has     8     door that takes you directly out of the house in case that the house collapses(倒塌), you can get out of the basement.

To protect against natural disasters, safety measures need to be taken by governments. Communities need to have small plans in place because     9     the happening of a disaster. And the nearest people that can help you will be those     10     (live)in your neighborhood.

10 . Zheng Haiqiang and Ni Decong rose early on Jan. 24, before the break of dawn, to monitor Hainan gibbons (长臂猿). After a one-hour hike, they heard the animals howling, located their positions, and excitedly found one holding a baby cub.

There are 20 gibbon species recognized worldwide, of which six are known to come from China. The Hainan gibbon is the most endangered of them all and one of the world’s rarest primates. They can mainly be found in Bawangling National Nature Reserve in Changjiang county, western Hainan, which is part of the Hainan Tropical Rainforest National Park.

Forty years ago, Bawangling formed a monitoring team, which consists of forest rangers and experienced villagers. The members of the monitoring team, like Zheng and Ni, will get up at 4 am every day. Science and technology help to scope out and predict locations where they may be able to observe the gibbons, and then they’ll wait for them to start howling at around 6 am, before taking photos and recording the lives of the gibbons.

The Hainan gibbons are a critically endangered and important flagship species. They serve as an indicator of the health and stability of the tropical island’s entire ecosystem, according to Qi Xunming, director of the Education and Publicity Division of Bawangling Branch of Hainan Tropical Rainforest National Park Administration. “If the number of Hainan gibbons increases, it indicates that the local environment is healthy, complete and functioning well”, Qi says.

To educate people on the island’s exclusive residents, exhibitions have been held in schools and communities across the province. From Oct. 24 to 31, a science exhibition, Into the Mysterious “Gibbon Universe” of the Bawangling National Nature Reserve-the Familiar and Unfamiliar Facts of Hainan Gibbons was held at Hainan Library. With interesting, vivid and informative pictures and illustrations, the exhibition presented the living habits and population changes of Hainan gibbons, as well as the effects of conservation on the animal and its habitat.

“Hopefully, with more education and publicity, the national park administration will recruit more talents, and young people with a relatively high educational background will join the monitoring team”, Qi adds.
