Methane is one of the biggest drivers of global warming.About 95% of methane emissions from cattle come out of their mouths and noses.The common method to design cattle feed additive（飼料添加劑） helps in the reduction of methane gas in' cattle's stomachs.However，chemical additives may become a problem for animal life and also the products.
A British company has come up with a cow mask，which breaks down methane，a more harmful greenhouse gas than carbon dioxide，into CO2，and water.The company，named Zelp，was founded by brothers Francisco and Patricio Norris，children of Argentine-based cattle keepers.According to the company，the mask is able to reduce up to 60 percent of methane emissions in cattle.
Unlike a human face' mask，the cow mask↓doesn't cover the mouth.It sits just over the nose，helping it to catch methane from breathing and burps（打嗝）：A sensor（感應(yīng)器） on the device detects what percentage of methane the cow breathes out.As the methane reaches a certain level，a chemical reaction turns it into carbon dioxide and water.
The mask also works as a smart device for cows.It monitors cattle location through a GPS chip，besides measuring feeding activity.Norris brothers believe that it will help cattle owners identify early symptoms of a disease and help reduce the cost of farms.
The device has successfully passed trials conducted in institutions in Argentina besides UK's Royal Veterinary College.As global meat consumption is set to increase by 70 percent in the next 30 years according to FAO，so will the demand in cattle and dairy industries.Thus，the Norris brothers believe that their cow mask will be one step in the right direction in the fight against global warming.
（1）Why does Zelp develop the cow mask？ CC
A．To help cattle eat safely.

A．How the mask works.
B．When the mask detects the gas.
C．Why the mask benefits the cow.
D．How the mask fits on the cow's head.

A．Giving cows a good appetite.
B．Tracking the cattle's movements.
C．Curing the cows' mild diseases.
D．Regulating the cattle's feed intake.
（4）What is the Norris brothers' attitude towards the future of their device？ DD

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 -
