A

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the dilemma. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is — politics, the laws of physics, or the proper way to break an egg — the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority — someone who actually knows something — and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

Nobody likes home economics (家政学). But restoring the program could help us in the fight against obesity and chronic (慢性的) diseases today.

The home economics movement was founded on the belief that housework and food preparation were important subjects that should be studied scientifically. The first classes occurred in the agricultural and technical colleges that were built in the 1860s. When most departments of universities rejected women, home economics was a back door into higher education.

Indeed, in the early 20th century, home economics was a serious subject When few people understood germ (微生物) theory and almost no one had heard of vitamins, home economics classes offered vital information about washing hands regularly, eating fruits and vegetables and not feeding coffee to babies.

However, today we remember only the fixed ideas about home economics, forgetting the movement’s most important lessons on healthy eating and cooking. Too many Americans simply don’t know how to cook. Our diets, consisting of highly processed foods made cheaply outside the home, have contributed to many serious health problems. In the last decade, many cities and states have tried to tax junk food heavily or to ban the use of food stamps (食品券) to buy soda. Clearly, many people are doubtful about any governmental steps to promote healthy eating. But what if the government put the tools of obesity prevention in the hands of children themselves by teaching them how to cook?

My first experience with home economics happened two decades ago when I was a seventh grader in a North Carolina public school. A year later, my father’s job took our family to Wales, where I attended a large school for a few months. It was the first time I had ever really cooked anything. I remember that it was fun, and with an instructor standing by, it wasn’t hard. Those lessons stuck with me when I first started cooking for my husband and myself after college and they still do. Teaching cooking in public schools can help solve some problems facing Americans today. The history of home economics shows it’s possible.

1.Home economics______.

A. is a subject becoming more and more popular with Americans

B. is often used to help fight against obesity and chronic diseases

C. once offered women a. special approach to university education

D. was first taught in the agricultural and technical colleges in the early 1900s

2.The third paragraph mainly tells us______ .

A. the importance of regular hand washing

B. the health benefits of fruits and vegetables

C. the contents of home economics classes in the early 20th century

D. the significance of teaching home economics in the early 20th century

3. In the opinion of the author, how should we fight against childhood obesity?

A. Children should be taught how to cook.

B. A heavy tax should be put on junk food

C. Healthy eating should be promoted at school

D. Using food stamps to buy soda should be banned

4.What does the author imply in the last paragraph?

A. Her family moved frequently in her childhood.

B. Cooking classes have a far-reaching influence on her later life.

C. To receive a better education, she went to a large school in Wales.

D. Teaching cooking is the key to solving Americans’ health problems.

The 3D-printing industry is accelerating its efforts to help fight the new coronavirus and the disease it causes, COVID-19.

On Tuesday, HP announced it’s working with those who bought its 3D printers to make medical face shields, hands-free door openers and an adjuster for face masks for medical staff who often must wear them for hours. It’s also testing “hospital-grade” face masks meeting the higher-end FFP3 (过滤式面罩) standard and parts for simple emergency ventilators (呼吸机) and it’s looking into nasal swabs to test for COVID-19 infection. HP also is offering free downloads of its 3D-printed medical equipment designs.

Carbon, whose 3D printers are used to make everything from bicycle seats to teeth straighteners, said it plans to send face shield designs to its network of customers who’ve bought its 3D printers. Carbon co-founder and Executive Chairman Joseph DeSimone said on Monday the company expects to send the designs by early Tuesday.

3D-printcr makers typically sell their products to others that actually do the 3D printing. One such customer, Ford, said Tuesday that it’s made 1,000 face shields and shipped them to Michigan hospitals, with plans to make 100,000 face shields a week. It is also working with 3M and General Electric on respirator masks and ventilator designs.

The effort is one of several to apply 3D-printing technology to the fight against coronavirus. 3D printing isn’t as fast at churning out products as conventional mass production methods. But 3D printers are flexible and able to make many different parts anywhere there’s a printer and raw materials like the plastic resins Carbon printers use.

Some 3D-printing efforts have focused on ventilators, which expected to be in short supply with a surge of COVID-19 patients suffering from respiratory (呼吸器官) problems. Also in short supply arc N95 masks that can be useful in reducing the likelihood a wearer will spread COVID-19 to others.

Carbon’s DeSimone is cautious about the enthusiasm, though, saying that regulatory approval is important and that 3D-printcr enthusiasts shouldn’t be making components not intended for close human contact that might release unhealthy gases.

1.What is the passage mainly about?

A.An introduction about 3D-printing.

B.The 3D-printing industry’s efforts to help fight COVID-19.

C.The products that 3D-printing makers sell.

D.How 3D-printing makers produce medical equipment.

2.HP announced to help its customers to make the following products except for_____________.

A.medical face shields B.hands-free door openers

C.an adjuster for face masks D.emergency ventilators

3.Which of the following is true according to the passage?

A.Carbon’s company will finish its design after Tuesday.

B.Ford has made 1,000 face shields end plans to make 10,000 more in a week.

C.3D printers arc more flexible than traditional mass production methods.

D.Most 3D-printings focus on making ventilators and N95 because of their short supply.

4.What can be inferred from the last paragraph?

A.3D-printing may release unhealthy gases.

B.DeSimone is cautious about 3D-printing.

C.Carbon’s company didn’t gain regulatory approval of making medical equipment.

D.3D printers aren’t enthusiastic about making components designed for close human contact.
