1 . In today’s world, almost everyone knows that air pollution and water pollution are harmful to people’s health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.
People who work and live under noisy conditions usually become deaf. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave (织) cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people’s life difficult and unpleasant, or even make people ill or even drive them mad.
It is said that a continuous noise of over 85 decibels (分贝) can cause deafness. Now the governments in many countries have made laws to control noise and make it less than 85 decibels.
In China, the government is trying to solve not only air and water pollution problems but also noise pollution problems.

2 . 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.
| A．Everybody wants to breathe fresh air. |
| B．That money could have been spent on parks. |
| C．How do you feel when you see people littering around? |
| D．In the future there might be more waste than fish in the ocean. |
| E．Litter can go into the soil and water and pollute our drinking water. |
| F．We need to stop littering for us, for the environment, and for the planet. |
| G．Did you know every day almost 8 million pieces of litter go into the ocean? |
3 . Blue Planet Ⅱ’s latest episode (情节) is about how plastic is having a terrible effect on the ocean and slowly poisoning our sea creatures. Researchers have also found that sea creatures living in the deepest place on Earth, Mariana Trench, have plastic in their stomachs. Indeed, oceans are drowning in plastic.
Though it seems that the world couldn’t possibly function without plastic, plastic is a very recent invention. The first plastic bags were introduced in the 1950s, the same decade (十年) that plastic packaging began gaining popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastic pollution research, for example, is still a very early science.
We put all the plastic into the environment, but we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is expected to kill millions of sea animals every year. Hundreds of species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their stomach. Ninety percent of seabirds are now eating plastic regularly. By 2050, that figure is expected to rise to 100 percent.
And it’s not just wildlife that is threatened by the plastic in our seas. Humans are consuming plastic through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated (复杂的) as climate change. There are no ocean waste deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.
This is not a problem where we don’t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag — when taken collectively, these choices really do make a difference.

4 . Clean water is not only important for food production, but necessary for our life. However, large numbers of people in Asia and Sub-Saharan Africa are going without. The World Health Organization reports that almost 4,000 children die each day for dirty water or lack of water.
Agriculture is the primary user of water at 70-85% of fresh water in the world. Industrial uses of water don’t often come to mind, but you may be surprised to know that industry uses 59% of the water supply in developed countries.
Home use takes up only 8% in the world. But as cities grow, the local government has to cut down on water use. Many cities are turning to privatization (私有化) of water as a method of controlling use. The poor are paying as much as a quarter of their monthly income for water in some developing countries.
In 60% of large European cities, groundwater is being used at a faster rate. People are saving water by simply using less and being careful with what they do use. Sometimes it’s as simple as not throwing out water that they could use elsewhere.
In Australia overuse of water has always been a problem. The Australian government has encouraged households and industries to collect rainwater and reuse water from showers. Technology is helping householders for shower and bath water for reuse in toilets or gardens.
The U.S. Environmental Protection Agency has made a water saving program designed to encourage families and businesses to examine their water use and save more water. Good water management has been considered by scientists and the UN as the key to solving the water problem. We can all work together to protect our valuable water in our daily life.

With the
Air pollution is caused by the following
We should take some measures to fight
7 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
