    Did you see snow in your hometown last winter? Did you feel it was warmer than before?

“There have been 21 warm winters in China since 1986,” said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 °C , the temperature in North China has climbed 1.4°C in only 50 years.

China needs to take quick action to cut carbon dioxide (二氧化碳) emission (排放), because it’s the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20 and pollution emission by 10 in the 11th Five-Year Plan.

Can you slow global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.

Here are some pieces of advice to help you save the earth.

Wear used clothes. Wearing your brother's, sister's or dad’s old T-shirt means you save the energy.

Change your light bulbs (灯泡). Use energy-saving light bulbs. And don’t forget to turn off the lights when you leave a room and turn off your television and computer when they are not in use!

Ride the bus. Taking a bus saves a lot of oil every year.

Say no to plastic bags. The next time your parents go to the market, ask them to use baskets.

Open a window. Don’t use the air conditioner (空调), and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.

Make small changes in your daily life. Don’t use paper cups, bags and boxes.

It's time for all of us to do something to save the earth.

A.the oil B.carbon dioxide C.paper cups, bags and boxes D.televisions and computers

2.The word “energy” in the third paragraph means “_______”

1.B 2.D 3.B 【解析】 本文是一篇说明文。科学家们提出中国需要采取快速行动来减少二氧化碳排放,因为它是全球变暖的主要原因。作者同时给读者介绍了一些节约能源的建议。 1.细节理解题。根据第三段中的China needs to take quick action to cut carbon dioxide (二氧化碳) emission (排放), because it’s the main reason for global warming.可知,中国需要迅速采取行动减少二氧化碳排放,因为这是全球变暖的主要原因。由此可知,全球变暖的主要原因是空气中二氧化碳含量的增加。故选B。 2.词义猜测题。划线词所在句China set the goal of cutting energy use by 20 and pollution emission by 10 in the 11th Five-Year Plan.意为“在第十一个五年计划中,中国设定了这样的目标,能源使用减少20,污染物排放减少10。”由此可知,划线词energy意思是“能源”。故选D。 3.细节理解题。根据倒数第三段Open a window. Don’t use the air conditioner (空调), and let some fresh air in. When you have to use the conditioner, set the temperature higher in the summer and lower in the winter to save energy.可知, 打开一个窗口。不要使用空调,让一些新鲜空气进来。当你不得不使用空调的时候,在夏天把温度调高,在冬天把温度调低,以节省能源。由此可知,空调的使用可能是浪费能源。故选B。
