Valerie Bolduc is exploring a path under a four-lane highway to fit wildlife cameras，when she gets stuck in the mud. "I am really stuck，" says the road ecology student，trying to pull her feet out of a streambed that travels through the concrete culvert（涵洞）of Quebec Route 117. "I do not want to be a deer going through that."
Bolduc's dilemma makes evident the risks for wild animals using the same path.
A warming climate is pushing many animals to migrate toward higher latitudes（緯度）to remain within their desirable environments，but that comes with risks as they cross dangerous areas，such as highways.In eastern Canada，Bolduc and other researchers and conservationists are trying to preserve safe corridors（走廊）for wildlife.
The motion-activated cameras they have brought will record which species are using the tunnels.An outward-facing camera will identify what animals approach but do not enter，perhaps prevented by traffic noise，the tunnel's size or other factors.
Bolduc explains that this highway running through southern Quebec separates a series of Canadian national and regional parks on either side，along with their animal populations. "It's super important，" she notes， "because the animals want to move north and they encounter these and then can they move through？Will they get hit by a car？We'll need to figure that out.And we need to help them，at least I want to help them."
After finishing fitting their cameras on the northbound side of the highway，Bolduc and her team decide they need an alternate path to the other side to avoid another misfortune in the mud. "We're generally trying to be safe，" Bolduc says， "but for the animals，this is their life!"
（1）What can we learn from Bolduc's experience of being trapped？ DD
A．It is difficult to fit wildlife cameras.

C．Road conditions of the highway are unexpected.
D．It is dangerous for wild animals to cross this area.
（2）What do these animals move to higher latitudes for？ 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 -
