英國皇家學會（Royal Society）的科學家們發(fā)表的一份報告稱，在線收看電視節(jié)目時，選 “標清模式” 可以減少碳排放量。

The report says digital technology produces up to 6% of global emissions, but the authors say there are ways to lessen the impact.

這份報告稱，數字技術產生的碳排放量占全球排放總量的6%，報告的作者說，有方法可以減輕這一影響。

One is for people streaming music to turn off the video if they’re just listening, not watching. Another is to keep appliances for longer because each new appliance creates CO2 emissions when it’s manufactured. So, if people keep their phones for four years instead of two, the report says, the impact is halved. Buying a device secondhand or sharing equipment also helps.

一種方法是，如果在線聽音樂的人們只是在聽，而不是在看音樂，那么就可以關掉視頻。另一種方法是延長電器的使用壽命，因為制造每個新電器時都會產生二氧化碳排放。因此，這個報告稱，如果人們的手機使用壽命是四年，而不是兩年，其影響則會減半。同時，購買二手電子設備或與他人共享設備也會幫助減輕影響。

On the other side are the underplayed benefits of digital to save energy: why heat your whole home, the authors ask, if you can fit digital controls, so you only heat the room you're in?

另一方面，數字節(jié)能的好處被低估了。報告的作者表示，與其給整個家供暖，不如安裝數字控制器，這樣你只需要給自己所在的房間供暖。

閱讀理解：請在讀完上文后，回答下列問題。

1. True or false? By turning off a video you’re listening to and not watching, you can save energy.

2. What percentage of global emissions does digital technology produce?

3. According to the report, what will happen if people keep their phones for four years instead of two?

4. What can we do to save energy using digital technology when trying to heat our homes?

答案

1. True or false? By turning of a video you’re listening to and not watching, you can save energy.
True. One way to lessen the impact of digital technology on global emissions is for people streaming music to turn off the video if they’re just listening and not watching.

2. What percentage of global emissions does digital technology produce?
Digital technology produces up to 6% of global emissions.

3. According to the report, what will happen if people keep their phones for four years instead of two?
If people keep their phones for four years instead of two, the impact of CO2 emissions through manufacturing is halved.

4. What can we do to save energy using digital technology when trying to heat our homes?
If possible, you can fit digital controls. In this way, you can save energy by heating the room you’re in, instead of heating the whole home.
