【题目】中国政府采取了许多有效的措施来改善我们的环境。

_________________________________

【答案】Chinese government has taken many useful measures to improve our environment./Chinese government has done something useful a lot to improve our environment.

【解析】

此句强调过去的动作给现在带来的结果,应用现在完成时(have/has +过去分词)。Chinese government 中国政府,作主语时,指整体看作单数,故用hastake useful measures to do sth表示“采取有效的措施做某事”,take过去分词takendo something useful to do sth.也表示“采取有效的措施做某事”,do过去分词doneimprove改善。故答案为Chinese government has taken many useful measures to improve our environment./Chinese government has done something useful a lot to improve our environment.

【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.
