1Most of us are aware that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution. But recently, some “green truths” have been shown to be only half true, or even completely false. Here are some common ones. Which are really green

Paper shopping bags are better than plastic ones.
2Plastic bags cause litter and are a danger to wild animals, which mistake them for food. It takes hundreds of years for plastic to break down, but much less time for paper. Because of this, people think paper bags are the better environmental choice.
垃圾
把…错当成…
It takes some time for sb./sth.to do sth.

3However, making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water. The process also produces more greenhouse gases.
4In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when you go shopping.

Read the effects and complete the causes and measures of these according to the passage.
1. Making a paper bag uses more energy and water than making a plastic bag. It also produces more greenhouse gases.
Paper bags are not good for the environment.
CAUSES
EFFECTS
MEASURES
Take a reusable bag with you when you go shopping.
When you turn off a device, it stops using power.
5When we turn off a device, such as television, it goes into stand by mode. Devices in this mode still use power, and older devices in stand by mode can use even more. This happens because electricity continues to leak from the device, even when it is turned “off”. To make sure your appliance is in fact off, remove the plug from its power supply.

2. Devices turned off go into stand-by mode and still use power.
EFFECTS
Turning off a device won't stop it from using power.
MEASURES
Remove the

power supply.
Eating local food is good for the environment.
6It seems like common sense: eating local food? should be better for the environment, because it does not need to be transported long distances and kept cold during transport. Unfortunately, it is not that simple. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases.

In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away—even taking into account its transport.

3. Local produce sometimes might use more energy and produce more greenhouse gases.
Eating local food isn't always better for the environment.
No suggestions.
It's better to take a shower than a bath.
7It depends on how long you spend in the shower and how large your bath is. If you spend more than eight minutes in a shower, you‘ll use as much water as in a bath—about 50 litres of water. Therefore, the key is to keep your shower time as short as possible.
8Environmental awareness is now part of daily life. But it’s worth checking common ideas and opinions to see what’s really green.
as...as possible尽可能...
be worth doing sth.某事值得被做
动名词的主动形式表示被动含义
CAUSES
4. If you spend more than eight minutes in a shower, you’ll use as much water as in a bath--about 50 litres of water.
EFFECTS
It’s not always better to take a shower than a bath.
MEASURES
Keep your shower time as short as possible.

Dear John,
Glad to hear from you! I am sorry to hear that you have been ill for days and hope you have got better now. I’m writing to persuade you to take more exercise after class.
You have studied so hard that you have had no time for exercise. But it is really harmful to your health. First of all, exercise can improve your physical condition and refresh your mind. Secondly, after one or two hours of exercise you can study better than now. I think only have a strong body, you can keep on studying without feeling bad or ill. Otherwise, your study will be interrupted from time to time by sickness.
I do hope you can take my suggestion into consideration and make a final decision.
Looking forward to your quick reply.
Yours,
