5 . In a paper published recently in Nature Communications, the authors, including experts from China’s Tsinghua University, said that most of the current electricity demand in advanced, industrialized nations can be met by some combination of wind and solar power. “Wind and solar could meet more than 80 percent of demand in many places without crazy amounts of storage or additional generating ability,which is the critical point (临界点),”said co-author Steve Davis,UCI professor of Earth system science,“if we want to have a zero-carbon emission (排放) future without using fossil energy resources”.
The team analyzed 39 years’ worth of hourly energy demand data from 42 major countries to evaluate the adequacy of wind and solar power resources to serve their needs. They found that a full shift to sustainable power resources can be easier for lower-latitude (低纬度的) countries,which can rely on solar power availability throughout the year. The researchers highlighted Germany as an example of a relatively smaller country, in terms of land mass, at higher latitude which will make it more challenging to meet its electricity needs with wind and solar resources.
“Historic data show that countries which are farther from the equator (赤道) can occasionally experience periods during which there is very limited solar and wind power availability,” said lead author Dan Tong, assistant professor of Earth system science at Tsinghua University. “One recent occurrence of this phenomenon in Germany lasted for two weeks, forcing Germans to turn to dispatchable (可调度的) generation,which in many cases is provided by fossil fuel-burning plants.” Among the approaches the researchers suggested to alleviate this problem are building up generating capacity, developing long-term storage capabilities and pooling resources of multiple nations on a continental land mass to make the burden lighter to a certain country.
“Europe provides a good example to help people produce net-zero carbon electricity,” said Tong. “A lot of consistency and reliability could be provided by a system that includes solar resources from Spain, Italy and Greece with plentiful wind available in the Netherlands, Denmark and the Baltic region.”
1. What does Steve Davis imply by saying “critical point”?A.Carbon emission will be reduced by using wind and solar power. |
B.Electricity demand will be beyond human control in the future. |
C.Electricity generating can be replaced by wind and solar power. |
D.Fossil energy will be used with zero-carbon emissions in the future. |
A.Having a large land of its own. | B.Having a small population. |
C.Being developed in all respects. | D.Being located near the equator. |
A.Ease. | B.Stress. | C.Accept. | D.Arrange. |
A.People can solve increasing energy demand in the future like Europe. |
B.Most countries in Europe have a lot of solar resources to make electricity. |
C.Europe has done a good job in producing net-zero carbon electricity. |
D.Countries like Spain, Italy and Greece have plenty wind resources. |

Last winter vacation, I went to an open cloth market located in Seoul to buy a jacket. At this market, you can buy a lot of clothes at really good
I got the brilliant idea of putting only $60 in my pocket to play
At that time, I realized I really could get that jacket for$60, so I pretend to be
After checking my wallet, he agreed to sell me the jacket
9 . These days, if we’re not staring at our smartphones, we are sitting in front of computers. And more than half of office workers have reported the symptoms of eye strain (眼疲劳).
Get regular eye tests. If you work on a computer every day, experts recommend having a comprehensive eye exam every year to detect (发现,查明) problems before they develop.
Take breaks.

C.You can make the text larger. |
D.This reduces the light your eyes are exposed to. |
E.This may not always be practical if you have a busy job. |
F.Staring at a screen continuously for hours causes problems. |
G.During this test, tell the doctor how often you use your phone and computer. |
