Green Classroom Competition

(Cuộc thi Lớp học Xanh)

1. Listen and read.

(Nghe và đọc.)

Nam: Hey guys, look at this notice! Our school is holding a Green Classroom Competition. The greenest classroom will win an ecotour!

Mark: How exciting! But how will the classrooms be judged?

Nam: It says here that classrooms will be judged on the following: raising environmental awareness, reducing our carbon footprint, and using resources efficiently.

Mai: I guess we should start by cleaning up our classroom more frequently and having more plants in it.

Nam: Yes, this is the easiest thing to do, but we also need to change our classmates' behaviour so that we can develop eco-friendly habits in our class.

Mark: That sounds harder. I notice many of our classmates buy plastic water bottles every day and throw them away after a single use.

Nam: Plastic takes hundreds of years to decompose, which is certainly not good for the environment.

Mai: Well, we can place a big jug full of drinking water in the classroom so that we can refill our reusable bottles.

Mark: Good idea! Now, to reduce our carbon footprint, we should also make sure we turn off the lights and air conditioners before leaving the classroom. Sometimes people rush out and leave them on, which is a waste of electricity.

Mai: Sure. Why don't we place some brightly coloured signs next to all doors to remind people?

Nam: So many good ideas already. Let's meet after school to discuss more. I hope our class wins the ecotour!

Mark: That'd be fantastic!

Mai: Yes. Let's do our best!

GO GREEN WITH PLASTICS!

Plastic has become very common in our daily life; however, most plastic items take up to 1,000 years to decompose in landfills. Can we enjoy the convenience of plastics and a greener world at the same time? Our readers have sent us many emails with useful tips this week.

... I try to use fewer plastic bags when shopping. The supermarket near my house even provides cardboard boxes, so I can pack my groceries and get rid of plastic packaging! When I must use plastic bags, I try to reuse them again and again instead of throwing them away after a single use. ...

Hai, 18

… I know how convenient it is to buy a bottle of water from a vending machine or a supermarket; however, I always bring my reusable water bottle. All I have to remember is to fill my bottle before going to school, and then use the water filling stations or drinking fountains at school. ...

Phuong, 16

 ... I always reuse plastic takeaway containers. I use them to store portions of cooked food and keep leftovers in the fridge, which is also better for the environment. ...

Hoang, 15

… I have learnt that most plastic containers have numbers at the bottom to show the type of plastic they're made of. So when you recycle a bottle, for instance, remove the cap because a bottle often has number 1 on it while the cap often has number 5. Numbers 1 and 2 are the most widely accepted plastics for recycling. ...

Ha, 16

...When I started recycling, I made the mistake of putting some plastic takeaway containers with some leftover food into the recycling bin. The next day, the whole bin was contaminated, so all the recyclables were taken to the landfill instead. So now I always rinse out containers before recycling them. ...

Binh, 17

4. Solutions (Giải pháp)

A. ____

This report describes the problem of single-use plastics in our school and suggests three main solutions to the problem.

B. ____

Many students at our school buy bottled water or takeaway food. As a result, hundreds of water bottles and single-use plastic containers are thrown away every day. Besides, students often put containers with leftovers in them into the recycling bin, which can lead to contaminating the recyclable waste. This means our school produces a lot of plastic waste that goes to landfills and has a harmful effect on the environment.

C. ____

To solve this problem, we propose the following solutions. First, we suggest that the school should provide more recycling bins. Second, the Youth Union should hold regular sessions to teach students how to recycle properly. Third, we recommend that we make use of plastic waste in arts and crafts projects, for example, for making plant pots or bird feeders.

D. ____

Reusing and recycling single-use plastics will lead to a greener school environment and help promote a green lifestyle among young people. Therefore, we recommend you put the suggested solutions into practice as soon as possible.

HOW GREEN ARE OUR FESTIVAL TRADITIONS?

Festivals come with many traditions that bring happiness and joy. However, some of these customs may not be environmentally friendly, and may need to be changed for a sustainable future. Below are three of them.

1. Balloons and sky lanterns

In countries such as China, India, and Japan, releasing balloons or sky lanterns provides a spectacular sight. They are also flown for bringing good luck and sending wishes to the sky. However, the litter left behind the balloons and lanterns is hard to decompose. The frames of the lanterns can harm wild animals, and many animals mistake the balloons for food. Lanterns also caused wildfires in the past.

2. Fireworks

In Australia, the US, and many other countries, there are fascinating firework displays that people won't want to miss. However, fireworks actually release a lot of harmful chemicals into the air. Like sky lanterns, they can also cause fires.

3. Christmas trees

Real or fake Christmas trees are often displayed in almost every house, office, and shop during the festive season. When Christmas is over and the real trees go to landfills, they produce methane and carbon dioxide, which are two harmful greenhouse gases. Fake trees can be reused for many years, but during their production, harmful pollutants are released inta the air. And when they end in landfills, they will take hundreds of years to decompose.

2. Work in pairs. Suggest some green solutions to replace one of the traditions.

(Làm việc theo cặp. Đề xuất một số giải pháp xanh để thay thế một trong những truyền thống.)

How to develop eco-friendly habits

It's easy to adopt eco-friendly habits, and you can always start at home. Here are three tips to help you.

A. __________

There are so many electrical appliances around us, so if we could save even a little amount of energy from each appliance, it would add up to a lot. For example, there are likely to be tens of light bulbs in your house, so if you can replace them with LED ones, which are more energy-efficient and long-lasting light bulbs, you would save a lot of electricity. Before you buy a new appliance, you should also check its energy star rating, which shows how much energy it will use in a year. It's easy to understand: the more stars there are, the more energy you can save!

B. __________

To reduce your carbon footprint, you should also turn off the lights when you leave a room. In addition, keep your windows or curtains open during the day to let natural sunlight in or place more mirrors near a lamp to maximise lighting in the house. This can also help to reduce both energy consumption and your energy bills.

C. __________

While many people already know that turning off appliances around the house when they finish using them can save energy, they may not know that it is even better to unplug them. It is estimated that we could save up to 10% of our electricity bills every month simply by unplugging appliances when they're not in use. This is especially true for chargers. Many people tend to leave their fully charged phones connected, not knowing that it consumes around 2.24 watts. The figure goes up to 29.84 watts for laptops and computers. Leaving an empty charger plugged in has a similar effect, so make unplugging a habit!

1. Which of the following is the best heading for Section A?

A. Replace your light bulbs in your house!

B. LED light bulbs are the best!

C. Use energy-efficient light bulbs and appliances!

D. Check the energy stars!

2. Which of the following is the best heading for Section B?

A. Don't keep lights on all the time, but improve home lighting.

B. Turn off the lights when you're out.

C. Use simple tricks around the house.

D. Reduce your energy bills by keeping windows open.

3. Which of the following is the best heading for Section C?

A. Turn off unused appliances.

B. Turn off and unplug appliances when not in use.

C. Chargers should be unplugged.

D. Laptops and computers consume more energy than you thought.

4. Why should people try to save even a small amount of energy when using home appliances?

A. Because they often use the most energy in the house.

B. Because there are a lot of them around the house.

C. Because they are simple and easy to understand.

D. Because they are energy-efficient and long-lasting.

5. It can be inferred from the passage that an appliance rated five energy stars  than another one rated two stars.

A. is more expensive

B. is more advanced

C. consumes more energy

D. consumes less energy

6. It can be inferred from the passage that saving energy with home appliances can also help us to

A. improve home lighting

B. charge mobile phones faster

C. be safe at home

D. save money

7. Up to 10% of electricity could be saved if we

A. turn off lights

B. turn off electrical appliances when not in use

C. unplug electrical appliances when not in use

D. unplug phones and laptops when they are fully charged

8. It can be inferred from the passage that

A. adopting eco-friendly habits can be difficult at first, but we'll get used to them

B. LED light bulbs are eco-friendly because they use less energy and don't break easily

C. having fewer home appliances cannot reduce electricity consumption

D. we should unplug laptops rather than phones when they are fully charged

8. A. desires

B. ideas

C. goals

D. activities
