Around the world，people are realizing the significant problems caused by plastic waste.In the last 65 years，we have become increasingly dependent on plastic.It's easy to understand why：it's cheap to produce，light - therefore easy and cheap to transport - and incredibly strong and durable. （1）AA
One popular solution to the problem is to prohibit single use plastics.In the British supermarkets，shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food. （2）EE Some governments have even promised to ban the use of single-use plastic altogether by the not-too-distant future.
However，such plans may not be beneficial to eliminate （消除） the use of single-use plastic altogether. （3）CCThis is not just because of its low cost.It's also because infection and cross-contamination （交叉感染） are minimized.Plastic packaging is also crucial in the food industry.It ensures that food is safe for consumers.
Another issue is that alternative materials to plastic are often more environmentally harmful than plastic.Take paper bags，for example.（4）BB The process requires cutting trees，the emission of greenhouse gases and the production of poisonous chemical waste.Even more pollution is created when paper bags break down.
Clearly there is a need to reduce plastic waste and its impact on the environment. （5）DDIndustries that rely on single-use plastics for people's health and safety must be considered.Moreover，alternative materials must be evaluated strictly regarding their own environmental impact.
A.But it's these advantages that also make it so harmful.
B.They are very fragile and rarely reusable，unlike plastic.
C.One of the fields where single-use plastic has a vital role is medicine.
D.However，simply banning their single use may not be the best option.
E.It also boosts the local economy and save costs in managing littering and waste.
F.Bans on single-use plastic items like drinking straws are also coming into place.
G.According to a research，they require four times more energy when produced than a plastic bag.

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 -
