DI: What’s Really Green
Green
How much do you know about “green living”
Read the four subheadings from the passage and decide if they are T or F.
Scanning
Scan the passage and check your answers.
Did you tick the right answers
Some “green truths” have been shown to be only half true,
or even completely false.
Reading
Read the effects and complete the causes of these according to the passage.
Devices turned off go into stand-by mode and still use power.
Local produce might use more energy and produce more greenhouse gases.
If you spend more than 8 min in a shower, you’ll use as much water as in a bath.
Think and share
To protect the environment, use only green products.
cloth shopping bags
reusable water bottles
recyclable paper
LED light bulbs
...
Using green products alone cannot solve environmental problems. The most effective way is to reduce, reuse and recycle. Sometimes buying fewer things is much greener than buying more green products.
False “Green Truth”
Hybrid (混合动力产品) is better
Hybrid vehicles are a better choice for the environment than a standard vehicle. Again, this is a common false statement about green living. The truth is that Hybrid products, such as cars, take more energy to produce than they conserve. They are like bottled water in that respect. It takes more energy to make the item that is supposed to be green and environmentally better than the item itself gives back.
It is an unethical (不道德的) practice where companies mislead consumers by claiming to be environmentally friendly or sustainable.
It may involve simply changing the packaging of existing product while continuing to use unsustainable ingredients or practices.
Greenwashing

What should we do
Buy less.
Choose well.
Make it last.
P 3 However, making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water.
P5 When we turn off a device, such as television, it goes into
stand-by mode.
stand by a. be ready and waiting to provide help or to take action
做好准备
b. do nothing to stop bad things from happening
袖手旁观
eg. 你怎么能眼睁睁看着他遭人诬陷而袖手旁观呢？
How can you stand by and see him accused of something he didn’t do
c. to remain loyal or faithful to sb. 继续支持；坚持
eg. 朋友遇到麻烦时，我会支持她。
I will stand by my friend when she is in trouble.
P6 It is the production food, not its transport, that uses most of the energy and produces most of the greenhouse energy.
P6 In some cases, local produce might have used more energy and produced more green house gases than produce grown a long way away - even taking into account its transport.
