全球变暖 Global Warming

Gases such as carbon dioxide trap heat from the sun

This causes global temperatures to rise

This process is known as the greenhouse effect

Human activity is a major factor in the rise of the greenhouse gases

Factories and vehicles produce emissions and exhaust fumes

Many developing countries are becoming industrialized

The number of cars on our streets is growing

Cheap air travel is allowing more people to fly

Effects of Global Warming

Global warming will have a significant impact on our planet

Rising temperature will cause melting of the polar ice caps

Sea levels will rise

We can expect more extreme weather conditions

Flooding and droughts may become more common

人类对环境的影响 Impacts of humans on the environment

The increasing world population is putting pressure on natural resources

Fossil fuels like oil and gas are running out

We are destroying wildlife habitats

We have cut down enormous areas of rainforest

This has led to the extinction of many species of animals and plants

环境问题的解决办法 Solutions to environment problems

Governments could introduce laws to limit emissions from factories

They should invest in renewable energy from solar, wind or water power

They could impose “green taxes” on drivers and airlines companies

Government campaigns should promote recycling

Natural areas and wild animals should be protected

Individuals should also try to be greener

We should take fewer flights abroad for holidays

We should take public transport rather than driving

We should choose products with less packaging

We should recycle as much as possible

垃圾废物 Waste and rubbish

The amount of waster we produce has increased

This problem is a result of our consumer culture

Products are not made to last

If something breaks, we throw it way and buy a new one

Advertisers encourage is to buy the newest fashions

Packaging is an important part of selling

Most foods are sold in non-biodegradable plastics packaging

The amount of household waste is growing

乱丢垃圾 Litter

People do not think about the consequences of dropping rubbish

They assume that somebody is pad to clean the streets

Plastic packaging does not break down easily

Most of the litter seen on streets is fast food packaging

核能 Nuclear Power

There are several benefits to build more nuclear power stations

Fossil fuel like oil and gas are running out

Nuclear power is a sustainable energy source

It can be used to produce electricity without wasting natural resources

It could be replace the use of natural resources like coal, oil or gas

Nuclear power stations are cleaner than fossil fuel power stations

They could help to reduce carbon emissions that cause global warming The risks of accidents are being reduced

Nuclear Power: negatives

Opponents of nuclear power worry about the safety of power stations

The building of new nuclear power stations is unpopular

Nobody wants to live near one

Nuclear waste disposal is a significant problem

There is currently no way to decontaminate radioactive material

People worry that terrorists could steal radioactive materials

It is safer to produce energy from solar, wind or water power.
