Question

【题目】 The Earth is faced with a serious power problem now and all of us are affected by it. Should we leave everything to the government, or can we do something to save power? The answer is clear if not us, who? Let us look at how you can save power at home.

Computer. More often than not, we do not turn off our monitors (显示屏) even after we have shut down our computers. And we often leave our computers on when we walk away to do something else. Keep the monitor and the computer switched off when you are not using them. Start doing this even when at work. You will help save some of the earth's important power.

Air Conditioning. Put the temperature at the minimum or maximum strongest that you are comfortable with, depending on the season. Try not to put it at too-high or too-low temperatures. This helps you save lots of power.

Washers. Do you use your washing machine as frequently as you wish? Do you use your washing machine even when there are not many clothes to wash? Reduce the times of washing by cleaning plenty of clothes every time.

Television. Unplug (拔出插头) the power plug of your television set when not using it. This may not sound like a big deal but this little step will help oneself save power.

Fridge. Do you always put hot food into the fridge? Bring cooked food to room temperatures before placing it into the fridge. You can also spare power by bringing cold or frozen food out of the icebox a great deal ahead of the mealtime. Thus, you don't need to heat it.

本题的第3小题是词义猜测题。词义猜测题是阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。本题可以利用上文语境来猜测词意。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。
