课文结构用法分析
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

Para. 1
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.

Para. 2
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.

Para. 3 & 4
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.

Para. 5
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.

v. 生产n. 农产品
Para. 6
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.
在某些情况下
take...into account
把……考虑进去
Para. 6
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

(2) 强调主语或宾语且其为人称代词时，应注意仍用主格或宾格形式。
(3) 强调句的主句中的be动词只能用is和was两种形式。
(4) 强调主语时，that或who后面的谓语动词必须和主语在人称和数上保持一致。
