1 . As we all know, waste is extremely bad for the environment. Let’s talk about why litter is harmful to our streets and towns, our drinking water, and sea animals.
Waste can have a bad influence on our cities. Cleaning up litter costs US taxpayers (纳税人) and businesses $11.5 billion each year.
As you can see, waste is harmful in many ways.

7 . My husband and I always wanted to go to the Caribbean but didn’t know much about the islands or how we were going to afford it. By chance, a friend of ours in Australia mentioned “pet sitting” and that it is something you can do all over the world.
We quickly created an account on a pet sitting website and began searching for options. There were only a couple of sits available in that part of the world, but we tried our luck, sent a request, and to our surprise, landed a three-month job in Grenada, so our year was going to be taken up with Caribbean pet sits.
Inspired by a Canadian couple, we decided to start our own travel blog. We began by writing about The British Virgin Islands, highlighting the beautiful beaches. However, for every photo album of a beautiful beach, there were 10 photos of trash (垃圾). It was hard to ignore the plastic pollution issue, especially on such primitive and remote beaches. So, we began to share photos of the trash we saw and how much we could pick upon our daily dog walks.
The more we looked into plastic pollution, the more we realized the severity of the global plastic pollution. From that point, we used our platform to create awareness and highlight ways to say no to plastic and travel plastic-free. We changed our daily routines, our way of living, and even our diets to accommodate more organic foods and little to no plastic packaging.
It’s been over three years now and we continue to do what we can. This journey has led us to some amazing places, working with great brands and even organizing a country-wide beach clean-up campaign in Grenada.
Our aim now is to keep on going. We love connecting with like-minded people. It’s been amazing few years that was sparked by a conversation about pet sitting. Who would have guessed?

8 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by S02 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must care about the rise in pollution at the same time.
1. Why is our world becoming much smaller?| A．Thanks to the development of science. |
| B．Because of the rise in pollution. |
| C．Because the earth is being polluted day and night. |
| D．Because the earth is blown away by the wind every year. |
| A．Rubbish. | B．Water pollution. |
| C．Air pollution. | D．Noise pollution. |
| A．Because it’s bad for all living things in the world. |
| B．Because it makes much noise. |
| C．Because it has made our rivers and lakes dirty. |
| D．Because it makes us become angry more easily. |
| A．Many countries are making rules to fight pollution. |
| B．The problem of pollution is not so serious because there are not so many people living on the earth. |
| C．The pollution of the earth grows as fast as the world population does. |
| D．If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of S02. |
9 . Have you ever stopped to consider how empty the world would look without trees? Below are five of the top benefits that trees provide.
Trees help you heal faster. Natural environments, including forests, help you reach a more positive state of mind.
Trees reduce air pollution and improve respiratory (呼吸的) health. Trees take in many harmful pollutants from our environment.
Trees provide oxygen. Trees are like the lungs of our Earth. They supply us with oxygen while taking away our carbon dioxide and ask for nothing in return. A single tree can provide enough oxygen for four people.
Trees cool cities. Trees cool things down by offering shade and through evapotranspiration (蒸腾作用).
| A．Trees cheer you up! |
| B．Trees help reduce the effects of climate change. |
| C．This, in turn, affects your overall state of wellness. |
| D．In fact, large forests can influence regional weather patterns. |
| E．So plant more trees around your home if you want to feel cooler. |
| F．And of course, trees also provide plenty of oxygen for birds and other wildlife. |
| G．For example, in the US, forests remove 17.4 million tons of pollution per year. |
10 . A new study finds too much light at night can cut the number of seeds a plant produces. Researchers put up street lights in Swiss meadows, far from any real street. The setup mimicked (模拟) urban light pollution. In these now-light-polluted fields, flowers had 62 percent fewer night visitors—insect pollinators(传粉者)—than the flowers in
Cabbage thistles are the most common flowers in these meadows. Fewer insect visitors at night could mean less pollen (花粉) pollinated from plant to plant (the first step in producing seeds). “For the thistles, daytime pollinator visits didn’t make up for this loss at night,” says Eva Knop, an ecologist at the University of Bern in Switzerland. Overall, night-lit plants produced one-eighth fewer seeds than plants that got full nights of darkness did.
“Light pollution might affect a whole network of plants and their pollinators,” Knop and her colleagues now suggest. Indeed, night pollination is not just a lonely business for a few special plants. There are lots of links between production of pollen by night and that by day. Plants with a lot of night visits are often very busy by day, too. Light at night that decreases seed numbers could over time mean fewer new plants. And fewer plants could mean less food and shelter for daytime insects. Therefore, a lot of pollinators working day and night shifts could be affected, which is what Knop worries about.
The new study is the first to show how artificial light affects plants’ ability to produce seeds. The test is also unusual because it considers all kinds of insect pollinators instead of focusing only on night-flying insects. The researchers paid special attention to the cabbage thistle, but they also mapped which kinds of insects visited other plants by day or night.
