（disappear）of my licence plate.發(fā)布：2025/1/1 13:0:1組卷：1引用：3難度：0.9893．Though the COVID-19 pandemic has badly affected the food industry，the prefabricated food （預制菜） market has witnessed a fast growth.
"I bought some prefabricated food in late April when my community was locked down due to the coronavirus outbreak，" a Beijing-based resident Yu told Global Times. "It was then that I realized there were so many different sorts of prefabricated food.All you need to do is to put some water into the heating package and a fair meal would be ready in minutes."
Prefabricated food has become increasingly popular over the last two years，with plenty of companies entering the business and different kinds of productions keeping hitting the shelves.The total market scale for prefabricated food reached 345.9 billion yuan in 2021.It is expected that China's prefabricated food market will stay a high growth rate in the near future，with a market scale estimated to reach 1.07 trillion yuan in 2026.
Many investors have started to pour money into it.From 2013 to 2021，a total of 71 investments were conducted in the prefabricated food sector（行業(yè)）.Even so there are problems linked to the growth of the industry.For instance，the prefabricated food industry is made up of a long value chain from production，cold-chain logistics（冷鏈物流） to delivery，which requires companies to realize smooth operation.
In addition，the sector's product quality problem has also begun to come under the spotlight，becoming one of the most common complaints by consumers，according to an analysis released by China Consumer Association（CCA）. "There are prefabricated food products with no detailed labels and many restaurants do not inform customers when offering them prefabricated food." CCA's analysis said.
CCA emphasized that with the rapid development of the prefabricated food market，relevant rules need to be rolled out to promote the standardized development of the industry and to guide the industry's healthy growth.

These days，safety regulations-not to mention the modern sports fan's desire for a good view and comfortable seat-tend to keep stadium capacities（容量）slightly lower.Even soccer fans tend to have a seat each；gone are the days of thousands standing to watch the match.
For the biggest stadiums in the world，we have used data supplied by the World Atlas list so far，which ranks them by their stated permanent capacity，as well as updated information from official stadium websites.
All these stadiums are still functional，still open and still hosting the biggest events in world sport.
?Rungrado 1st of May Stadium，Pyongyang D.P.R.Korea.Capacity：150，000.Opened：May 1，1989.
?Michigan Stadium，Ann Arbor，Michigan，U.S.Capacity：107，601.Opened：October 1，1927.
?Beaver Stadium，State College，Pennsylvania，U.S.Capacity：106，572.Opened：September 17，1960.
?Ohio Stadium，Columbus，Ohio，U.S.Capacity：104，944.Opened：October 7，1922.
?Kyle Field，College Station，Texas，U.S.Capacity：102，512.Opened：September 24，1927.

These findings are evidence that dogs could be effective for mass screening efforts at places such as airports or concerts and may provide friendly alternatives for testing people who fear the tests，says Dominique Grandjean in France.
Dogs' noses also identified more COVID-19 cases than did antigen （抗原） tests，but sometimes mistook another virus for the coronavirus，Grandjean and colleagues found.What's more，evidence suggests the dogs can pick up cases 48 hours before people test positive by PCR.
In the study，dogs were trained in coronavirus detection by rewarding them with toys—usually tennis balls. "It's playtime for them，" Grandjean says.It takes about three to six weeks，depending on the dog's experience with odor detection，to train a dog to pick out COVID-19 cases from sweat samples.For detection，the dogs sniffed used face masks or housing sweat samples collected from human volunteers' underarms.Results showed that dogs perform as well as or even better than PCR tests for detecting the virus that causes COVID-19，F(xiàn)urton says.He and colleagues have used dogs at schools，a music festival and in a small trial screening airline employees for coronavirus infections.
One of the biggest advantages dogs have over other tests is their speed，F(xiàn)urton says. "Even with what we call a rapid test，you're still going to have to wait tens of minutes or even hours，where the dog in a matter of seconds can make a response." However，dogs take time to train and there currently aren't even enough dogs trained to detect explosives，let alone diseases，Otto says.
Another drawback is that people don't think of them as high-tech，though they're one of the highest-tech devices we have.
（1）What can we learn about the study from the first paragraph？
A．Dogs were trained to test COVID-19.
B．Sweat samples are perfect to test COVID-19.

D．PCR tests failed to meet public expectation.
（2）What's the disadvantage of using dogs for COVID-19 tests？
A．Dogs may be unfriendly to people when doing tests.
B．Dogs lack experience dealing with large screens.
C．Dogs may need a long time to identify the disease.
D．Dogs may recognize other diseases as coronavirus.
（3）What can we infer about trained dogs according to Furton？
A．They perform well at detecting COVID-19 virus.
B．They do better at detecting explosives than viruses.
C．They are widely used in public places like schools.
D．They like to be rewarded with toys after training.
（4）How does Otto view getting dogs to do COVID-19 tests？
A．Supportive.
B．Disapproving.
C．Fearful.
D．Confident.發(fā)布：2025/1/1 13:0:1組卷：2引用：4難度：0.5896．If such packaging is burnt，it will certainly give off

Duolingo set up its own test of English language ability.Jennifer Dewar works as an official（行政人員）at Washington University，which is one of the hundreds of universities in and outside the U.S.jye.ai now take the test results for international admissions.Duolingo created the test to make higher education available to more people worldwide.
The TOEFL and the IELTS cost between about ＄180 and ＄240.They are only given in several centers around the world.Some test-takers have to travel to take the tests，adding to the costs.However，Duolingo offers its test entirely over the Internet for ＄49.All test-takers need is a computer with a microphone，listening device and self-facing camera.
David Payne is a president for Educational Testing Service，which runs the TOEFL test.He agrees that improving availability of higher education is important.But he says general English knowledge isn't the only thing universities require.Universities need to know how successful a student will be in using the level of academic（學術的） English that their teachers will expect of them.But Duolingo may fail to show that.Payne said，"The tests for the academic market should provide the value that's necessary for making an important decision.And saving money doesn't seem worth it."
In a word，universities have to do their research to decide if any new tests work as well as traditional ones in their cases.It really comes down to a question for the universities about what's available，what the products show，and if they're satisfied with their choices.In general，having choices is important.
