Pollution means the damage we do to the environment with harmful materials. It has bad effects on people’s health and lowers their quality① of life. Pollution can also do harm to animals and plants. There are many different forms of pollution. Air pollution, land pollution and water pollution are the most common ones.① quality n. 质量4566-2Air pollution comes from many different sources① —not all of them are man-made. For example, sandstorms in deserts and the smoke from forest fires are natural sources of air pollution. In urban areas, dirty air is everywhere because of the fumes from cars and the waste from factories. Air pollution can affect humans by causing sore eyes andbreathing problems, especially inchildren and the elderly.① source n. 来源1234566-3Land pollution is caused by solid wastes like cans, bottles, plastics, etc. These things cannot be broken down quickly, or at all in some cases. Land pollution can affect animals and plants, and it makes the environment look very bad. Reusing materials can help reduce the amount of land pollution. Other methods include using the rubbish to make new land or burning the rubbish, but these two methods canpollute the water and air too.1234566-4People dump① waste into lakes, rivers, oceans, etc. The waste stays in the water or builds up at the bottom and causes water pollution. This form of pollution may also be caused by the air if the air is polluted. This can create acid② rain. When acid rain falls, it pollutes the water in lakes, rivers, oceans, etc. Soil erosion is one example of natural water pollution. It can cause problems if the soil blocks③ the flow of water and leads to flooding. Water pollution from humansources includes chemicals, waste fromfactories and human sewage.① dump v. 倾倒;丢弃
② acid adj. 酸性的
③ block v. 堵塞123456A Find the following words and phrases in the passage and match them with their meanings. 6-5cafbegd123456B Where do the different types of pollution come from? How do they affect our lives? Read the passage again and complete the table below.6-6Sandstorms in deserts
