Do you know what June fifth is
World Environment Day
World Environment Day is celebrated annually on 5 June and is the United Nations' principal vehicle
(主要策略) for encouraging awareness and action for the protection of the environment. First held in 1973, it has been a platform for raising awareness on environmental problems.
Now let’s watch a video to find the answer.
What are the problems the earth is facing
What are the problems the earth is facing
Forest disappearing
Species extinction
Ocean pollution
Lack of clean drinking water
Plastic pollution
Thinner ice caps
1. Which of the facts in the video do you find most alarming
2. What does the video want to tell us
2. Severe environmental problems we are facing nowadays make our future uncertain. It's time for everyone to take action now and make our planet a greener and safer place for our future generations.
Save Life on Earth
Earth, home to countless plants and animals for millions of years, has an uncertain future.
How many of us are aware that...
130,000 square kilometres of forest disappear every year
around 25,000 trees are cut down each day just to make toilet paper
each day, around 150 to 200 species of plants and animals become extinct-nearly 1,000times the natural rate of extinction
over 1 million animals are killed by ocean pollution each year
1 billion people don't have clean drinking water
a plastic bottle can take 450 years to break down
the ice caps are more than 50% thinner than they were 40 years ago
If we do not change our ways, we are at risk of ruining our planet and destroying manymore plants and animals. Some day in the future, there may be no tigers, no horses, nobutterflies, no dolphins and no whales nor will there be any trees or flowers. All of these things will be gone. And we will be gone, too.
Time is running out. Our planet needs our help.
It's up to us to decide together what happens next.

Useful expressions:
replace, invest, recycle, carpooling(拼车), classification of waste, green/clean energy, environmentally friendly lifestyles …
The environment has paid a high price for every country’s high economic growth. There are two aspects to the environmental damage. The first is the increase in air and water pollution. The second is the increase in carbon emissions (排放).
Explore the topic further
environmental damage
For a large and developing country like China, adopting policies for protecting the environment has effects on economic growth. For consumers and households, protecting the environment means adopting less-polluting lifestyles through conscious(有意识的) efforts for not polluting surroundings and using less carbon and energy-consuming appliances (器具).
How to protect
In recent years, a large part of China, especially Northern China has frequently been struck by smog. How does it come about The word “smog” is the combination of words “smoke” and “fog” to refer to smoky fog. It is a type of air pollution and usually forms in industrial areas or areas of high population. It releases large amounts of smoke or gases. And it will lead to respiratory diseases (呼吸道疾病) if people are exposed to smog for long. It’s time for us to take action to fight against smog!
environmentally friendly lifestyles
Walk or ride a bike whenever possible
Choose organically grown fruits and vegetables
Plant more trees
Use as less disposable cutlery as possible
Bring your own reusable bags
Cut down your
energy use
You can reduce the amount of waste you produce.
You can reuse the plastic bags rather than just
throwing them away.
Many items that you use can be recycled.
Repeat these three words daily:
reduce, reuse and recycle.
Let's enjoy a video

Global warming
What environmental problem does this cartoon refer to
What do you know about global warming
＊Global warming is the long-term warming of the planet’s overall temperature.
＊Greenhouse effect is an important and main cause of global warming.
＊The earth has some very important gases in the atmosphere that keeps us warm. When the sun heats the earth, these gases keep the heat on the earth's surface.
＊In a way, the earth is like a greenhouse.
But if the greenhouse effect becomes stronger, it could make the earth warmer than usual. Even a little extra warming of the earth may cause problems for humans, plants and animals.
What are the impacts of global warming
increase in extreme weather
more droughts and wildfires
rising sea level
less snow and ice
…
What can we do to deal with global warming

Smog comes from the words “smoke” and “fog”, and it is used to describe the air pollution in cities caused mainly by traffic and factories. Smog can be dangerous because it causes severe breathing problems and infections.

Tapescript
Lecturer: Good evening, everyone, and thank you for coming to today's talk. I'm Dr Brown and I'm going to talk about air pollution in cities - what we all know as “smog”. Please feel free to stop me if you have any questions. So, first of all, a bit of history. The term “smog” was first used in the 1800s in cities that had problems with smoke and fog.
Student A: Sorry for interrupting, but I believe it was in the 1900s.
Lecturer: Sorry, I made a mistake. You are right. It was in the 1900s. Thank you. London was one of the cities where smog caused big problems. In December 1952, it suffered from “The Great Smog”. It was a very cold winter, so a lot of coal was burned at home and in the factories. The problem was that there was no wind, so thick smog covered the city. Nowadays….
Student B: Excuse me, but can I just ask - did the smog cause any death
Lecturer: I'm afraid so. According to research, about 4,000 people are known to have died as a result of the smog, but that number could much higher. It was terrible! Nowadays, smog till exists, but is produced by chemicals coming from traffic and factories. However, governments are taking measures to reduce smog as much as possible. Now, let's look at what smog does to our health...
Student A: If I could just stop you again... Can you give us examples of these measures
Lecturer: Well, for example, factories must follow rules about what chemicals they use. In some cities, when there's smog, people have to pay to drive in the centre. Now, let's move on to the impact of smog on our health….
Listen again if necessary.
Useful expressions:

What do the students say to interrupt the lecturer politely
The classification of household waste aims to help people separate different types of waste. This is important because these different types of waste can be disposed of or recycled appropriately and effectively
Household waste can be roughly divided into:
* food waste
* non-recyclable waste
* recyclable waste, including paper, glass, plastic and use batteries
China plans to introduce household waste classification and sorting in the first batch of cities by 2020. Only Beijing, Shanghai, Tianjin and Chongqing are included in the first batch.
The target recycling rate in these cities has been set at 55% by 2020.
Student A
Work in pairs and talk about recycling.
Tell Student B about recycling using the information below. Be prepared to be corrected by Student B.
Student B
Used batteries are usually regarded as non-recyclable waste and should be disposed of separately.
The first batch of cities to introduce household waste classification and sorting includes Beijing, Shanghai, Tianjin, Chongqing and all capitals of provinces and autonomous regions.
The target recycling rate in these cities has been set at 35% by 2020.
Listen to Student A talking about recycling. Interrupt politely to correct him / her using the following information:
Think about another environmental problem and then make a similar conversation with your partner.
