I live in Minnesota，which is unfairly famous for terrible winters.Buffalo is far more wintry，whereas Seattle’s winters are more bitter.Our winters tend to be brilliantly sunny and cheerful.But，of course，it’s different for a visitor.
Lightweight thermal(保暖的) wear is good.Back in the day，we wore layers and layers of heavy woolens.A boy of 13 carrying 35 pounds of wet wool on his back does not feel very cold.Today you can buy outfits filled with goose feathers as well as thermal boots and caps to keep you warm.
When I was a youth，there was no such phrase as global warming.We never got warm，not even at night，when we slept under piles of blankets because Dad believed that if you couldn’t see your breath when you talked，then the thermostat(恒温器) was turned up too high and you were wasting fuel.So 45 degrees was room temperature，and we wore long woolens to bed.
We arose in the cold，dark dawn，and walked forth into the snowstorm to catch the school bus.We huddled(蜷缩) by the highway，praying for the bus to come，while wolves moved around eyeballing us for signs of sleepiness.When you have survived wolves，then the winters of today are a walk in the park.
Enduring winter is only a start—embracing(拥抱) winter is what you should struggle for.Winter gives a sense of purpose and saves one from a life of self-gratification，lying down and posting photos on Facebook.You have promises to keep.A sidewalk to clear.Two inches of snow over a layer of ice—you may as well set a leg trap for the elderly as leave the walk unswept.
You have children to raise.Remove their fingers from their smartphones，and lead them outdoors so they can absorb the wisdom of winter.We are animals.Life is not mainly about self-expression.It is about finding food and clothing and shelter，about sticking with the pack and not wandering off.Everyone is just as cold as you.No complaining.

4．What are Minnesota’s winters like in the author’s eyes?

As providers and caretakers(监护人)，adults tend to view the children as happy and free.After all，kids don’t have jobs to keep or bills to pay，so what do they possibly have to worry about?
Plenty! Even very young children have worries and feel stressed to some degree.Stress is a function of the demands placed on us.These demands often come from outside sources，such as families，jobs，friends，or schools.But they can also come from our feelings，for example，what we think we should be doing versus what we’re actually able to do.
Stress can affect anyone who feels at a loss，even kids.For kids in the kindergarten，separation from parents can cause anxiety.As kids get older，academic and social pressures also create stress，especially those who want to fit in their school are probably to get more stress.
Many kids are too busy to have time to play creatively or relax after school.Kids who complain about all their activities or who refuse to take part in them might be too tired and full of stress.Talk with kids about how they feel about the activities related to their courses.If they complain，you should consider stopping one activity for a period of time，or you can explore ways to help them manage their time and lessen their anxiety.
Another source of stress is world news.Kids who see scary images on TV or hear someone talk of natural disasters or ways may worry about their own safety and the people they love.Talk to them about what they see and hear on TV to help them understand what’s going on.
What’s more，be aware of some negative factors，such as an illness，or death of a loved one.When these are added to the everyday pressure kids face，the stress may appear.Separated or divorced parents should never put kids in a position of having to choose who they would like to live with.

A billionaire has recently made one of the biggest charitable(慈善的) donations to a university in China’s history.Chen Tianqiao donated $115 million to the California Institute of Technology(Caltech) to help advanced brain research.The donation will be spent deepening the understanding of how the brain works.Chen has been interested in brain research，believing it can shape the industries such as artificial intelligence and virtual reality.However，this huge donation has caused heated discussions among Chinese scholars and Internet users alike.
Many criticized him for choosing to give money to a foreign university rather than home institutes for brain research，which are developing fast and are on track to catch up with the US in just a few years.Rao Yi，a biologist at Peking University，even said the donation was a typical mistake.
Others，however，support his choice.They believe Caltech is a more reasonable choice compared to Chinese research institutions.Caltech has a long history and has taken a leading position in biology，and therefore it produces more efficient results.In addition，the results of the research benefit not only the American people，but also the rest of the world.
A similar controversial case started two years ago when Pan Shiyi，chairman of SOHO China，donated $15 million to Harvard University to help disadvantaged Chinese students.
Many believe that China is still behind in the management and use of donated money，and that as a result，Chinese charity donators are looking abroad.In comparison，Western countries like the US，which have a long history of donating money，have well-developed systems that use money efficiently.They can also provide full access for donors who want to track the use of the money.To get more donations，Chinese universities should be braver and more honest.They need self-reflection，rather than envy.

12．Why did Chen’s donation draw criticism?
A．It was not given to a Chinese university.
B．It was one of the largest charitable donations to Caltech.
C．It was not used efficiently in the US.
D．It was used in brain research.
13．What is the reason for some people in favor of Chen’s choice?
A．The Chinese are just too envious.
B．The achievements will benefit the whole world.
C．Caltech is a university with a longer history.
D．The fund can help disadvantaged Chinese students.
14．What is the author’s purpose in mentioning Pan Shiyi in the passage?
A．To suggest the enthusiasm of the billionaires.
B．To show off generosity of the billionaires.
C．To inform Chinese students are poor at academy.
D．To stress the disagreement over donating abroad.
15．What does the author think the Chinese universities should do to get more fund?
A．Explore artificial intelligence.
B．Develop efficient systems.
C．Grow fast and catch up with the US.
D．Educate more honest graduates.

To meet the global climate crisis that is approaching，big lifestyle changes are required of those of us.The good news is that our way of life can remain meaningful and worthy as our consumption becomes sustainable.
1 Eat less meat and move toward a plant-based diet.This is one of the most effective things we can do because the food we now produce and consume is destroying the very ecosystems that we depend upon for survival.Here are some of the grim facts.
The U．S.uses about one-half of its land for agriculture. 2 For example，the U．S.uses over 90 million acres of good agricultural land to produce corn，which is mostly fed to livestock(家畜)．
With 7.6 billion people on earth，the demand for food is enormous and constantly on the rise.It’s easy to feel we can’t make a difference. 3 We should not ignore the power of the choices we make.
Even one person can make a big difference by eating less meat and moving toward a plant-based diet and make contributions to the health of the planet as well as your own.Recognize how the food we eat is connected to other living beings.It often helps us make much wiser buying choices. 4 This way，we will help people around the world enjoy more eco-friendly and nutritious foods.
5 When you change your diet to be more sustainable，you become visible proof that changing our food habits is doable，healthy，and enjoyable.
A．Little things matter in your relationship with the earth.
B．By buying mindfully，we support local，affordable agriculture.
C．But we can change our diet to heal the earth as we heal ourselves.
D．Unfortunately，the majority is used to raise livestock or for crops consumed by them.
