The impact of the man-made climate crisis on Antaretica is scientifically undeniable：stable ice shelves are retreating，air temperature increased by 3 degrees Celsius，krill（磷蝦）numbers are declining，melting ice is contributing to sea level rise，and polar bears and seals are getting displaced."Antaretic biodiversity could decline substantially by the end of the century if we continue with business as usual."Jasmine Rachael Lee，lead author of the University of Queensland study says.
Published in the journal PLOS Biology，the study finds population declines are likely for 65%of the continent's plants and wildlife by the year 2100.The most vulnerable（脆弱的）species is the Emperor pengujye.ais.In October 2022，the U.S.Fish and Wildlife Service listed Emperor penguins as a threatened species under the Endangered Species Act（ESA），as experts predict the flightless seabird will see a 26%to 47%dip in its population by 2050."This listing reflects the growing extinction crisis and highlights the importance of the ESA and efforts to conserve species before population declines become irreversible（不可逆轉(zhuǎn)）."said Service Director Martha Williams at the time.
Aside from Emperor penguins，other Antarctic specialists，like the Adélic penguin and dry soil nematodes，were also highly vulnerable.We urgently need a combination of global and local conservation action to best conserve Antarctic species.Global action and global voices to help relieve climate change—because the biggest threat to Antaretica is coming from outside of it.And then we need local actions to help protect biodiversity against local threats and give them the best chance of adapting to climate changes.This will help to save our iconic （代表性的） species like the Emperor penguins and all of Antaretical's unique and highly adapted inhabjye.aiants.It will also help humankind，as we rely heavily on the priceless services the Antarctic provides in regulating our climate and capturing sea level in its ice sheets.

1．More than half of the food produced in Canada goes to waste．A shocking new study has shown that the level of food waste is far worse than previously thought，at 58%．Of that，about 85% of food waste is due to food processors．This differs from earlier studies，which criticized families for driving food waste and said they were responsible for 51% of food waste．
The study was carried out by Martin Hooch，the leading expert on food waste and the author of several previous studies on the subject．Reflecting on the study's findings，Hooch said，"It means stopping criticizing consumers．Sure，consumers are part of the problem，but they're not the problem．"
In the past，Hooch didn't master good data，particularly from the private factories，but relied on numbers collected by the food industry for purposes other than tracking（追蹤） waste．This time，however，Hooch worked directly with companies at all stages along the food production chain and interviewed over 700 experts in the industry．Clearly he found it hard to believe what he was seeing．
This is what they found：Food processing causes 34% of food waste．This is followed by production，which causes 24%．Next is manufacturing at 13%，then hotels and restaurants at 9%．Families cause only 14%，and market sales 6%．This should be a serious wake-up call for Canadians who would do well to examine their own food supply chains．Food waste is costly，not only in terms of dollars wasted，but also in resources like land，water，and so on．To be using these resources and wasting the product is totally irresponsible and unnecessary．
To make matters worse，when food is thrown into rubbish cans，it produces methane，a greenhouse gas 30 times more powerful than carbon dioxide （CO2）．At Canada's rate of food waste，that's like adding 12 million cars to the road．It seems that the food industry needs redesigning．Therefore，let's hope the government takes action．
（1）What did earlier studies say about food waste in Canada？
A．Food waste was better than expected．
B．Food went bad when it was processed．
C．Most of the food was wasted on purpose．
D．Families were to blame for food waste．
（2）How did Hooch do his study on food waste this time？
A．By studying data from the industry．
B．By tracking the whole production chain．
C．By collecting advice from experts worldwide．
D．By drawing a conclusion from the previous studies．
（3）Why does food waste have an effect on the environment？
A．Because it is harmful to the trees．
B．Because it pollutes the soil around it．
C．Because it gives off unpleasant smells．
D．Because it produces more greenhouse gas．
（4）What is the main idea of the text？
A．Canadians don't like to save food for future．
B．More than half of the food is wasted in Canada．
C．Families are mainly responsible for food waste．
D．The food industry is better redesigned in Canada．發(fā)布：2024/12/5 0:0:1組卷：9引用：5難度：0.5 -
