My father died when I was nine, and I remember doing the household chores(杂务)to help my mother. I hated changing the vacuum cleaner(真空吸尘器)bag and picking up things the machine did not suck up.
Twenty years later, in 1978, I was doing chores at home alongside my wife. One day the vacuum cleaner was screaming away, and I had to empty the bag because I could not find a replacement for it. With this lifelong hatred of the way the machine worked. I decided to make a bagless vacuum cleaner.
Easier said than done, of course. I didn't realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes(设计原型). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.
I just had a passion for the vacuum cleaner as a product, but I never thought of going into a business with it. In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters(滤网).
No one would license my idea, not because it was a bad one, but because it was bad for business.
That gave me the courage to keep going. Then, in 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million, I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.
Today, I still embrace risk and the potential for failure as part of the process. Nothing beats the excitement of invention. Go out and brainstorm your ideas. You are not bound to any rules—in fact, the stranger and riskier your idea, the better.

Recently, the phrase "hair loss" has been trending among young people in China. A recent report on overall health showed that hair loss ranked fifth among top health concerns, following bad skin conditions, depression and anxiety, poor sleep, and digestive tract(消化道)discomfort and illness.
But hair loss isn't just a concern for Chinese youth. It is an inconvenient reality for many people in China and the world over. According to a survey, 250 million Chinese people are troubled by hair loss, most of them between 20 and 40 years old. In the United States, about one in five people is suffering from hair loss.
There isn't really any single reason for hair loss. Humans naturally lose about 50 to 100 hairs each day, which usually regrow later. However, genetic and environmental factors can mean, for some people, these lost hairs won't regrow. In addition, certain factors can further worsen hair loss, including too much stress from work school, too little sleep, and a bad diet.
Is there anything you can do to protect your remaining hair? There are many products out there ready to help you keep a full head of hair. Shampoos, lotions, surgery, even laser-helmets say they can help. Hair loss treatments represent a $3. 6 billion industry in the United States alone. While many of these products make bold promises about their capabilities to restore your hair, the reality is that fixing your hair loss will ultimately depend on finding the specific causes.
If it is due to stress, lack of sleep, or poor nutrition, then a lifestyle change might not only stop hair loss, but also restart the growth of hair. For most young people who want to protect their receding(后移的)hairlines, it starts with their personal health. All they need to do is change unhealthy living habits and pay more attention to their psychological well-being.
1.What can we learn about "hair loss" from the passage?
A.It is common among most people in China.
B.It is the top health concern for Chinese youth.
C.Only Chinese youth are suffering from hair loss.
D.It bothers people of different ages and countries
2.What stops the regrowth of the lost hairs for some people?
A.Genetic and environmental factors.
B.Stress from work and school.
C.Too little sleep.
D.A bad diet.
3.What's the author's attitude towards many hair loss treatments?
A.Critical. B.Objective.
C.Optimistic. D.Supportive.
4.What's the author's suggestion to young people with hair loss?
A.To use hair-growth products.
B.To change unhealthy lifestyle.
C.To have a health check in hospital
D.To pay attention to physical well-being

Children may not be putting coins in piggy banks for much longer. With the move towards a cashless society, pocket money is moving digital.
To reflect this trend, many mobile budgeting apps for children have sprung up worldwide：GoHenry, Osper, and Gimi, to name but a few. These apps offer a simple money management service for children, often for a monthly fee paid by the parents. Parents can add money to children's accounts, set limits and monitor transactions(交易). Children can choose to save their money or spend it using a prepaid card.
These apps aim to teach young childrenfinancial concepts, such as budgeting, interest rates and income. For instance, the Swedish app Gimi—with 1.2 million users globally—has virtual savings jars where children can deposit money. Parents can pay children interest as they save. There is also a chores feature, where parents can pay children for completing household tasks. The account is attached to a prepaid card that is currently available in Sweden only, but is expected to be launched elsewhere in Europe in 2020.
Haglund, CEO of Gimi, believes the app can teach children responsible spending habits. "You don't become better at money management just because you have a degree in economics. It's more about the attitude and the relationship you have with parents' money when you're 6 to 12 years old," he says.
But Catherine Winter, managing director of financial capability at The London Institute of Banking and Finance, warns that while digital tools can help there needs to be a more structured approach to financial education. The area should "have regular, dedicated, classroom time and ideally should be taught as a standalone subject," she said. “Children would then have the right context and foundation to get the most out of both the apps and their money.”
1.What does the underlined part "this trend" in paragraph 2 refer to?
A.Putting coins in piggy banks
B.Pocket money moving digital
C.Mobile budging apps springing up.
D.Money management service being offered
2.What do we know about the Swedish app Gimi?
A.It pays children interest as they save.
B.It has 1. 2 million users all over Sweden.
C.It can teach children concepts related to money
D.It is attached to a credit card available in Sweden only.
3.What can we learn from Winter's words?
A.Digital tools can help a lot with spending habits
B.Money management requires financial capability.
C.A regular classroom-based financial education is needed.
D.Children can get the most out of their money with the apps
4.What's the passage mainly about?
A.The rise of the digital piggy bank.
B.The trend towards a cashless society.
C.The importance of financial education.
D.The popularity of money management apps.

Calming Down before the Speech
Public speaking makes almost everybody anxious. Even seasoned speakers need to calm themselves down（or pump themselves up）before they give a presentation.1.
Practice in front of others. If you only practice speaking when you're alone, you're more likely to get anxious when you deliver the speech to an audience.2.Practice a little every day, but on the night before you deliver the speech, don't practice. Just relax. If you notice that there's a section of the speech that makes you the most nervous, practice it extra. For instance, if you always get nervous right at the beginning, devote extra Practice time to the beginning.
Visit the location of your speech. If you can, spend some time in the place where you will give your speech.3.If the location is in your workplace or school, visit it frequently to practice. Relax there as well. If the location won't be accessible until the day of the speech, try to come a little early so you can adapt yourself to the environment.
4.Write down what makes you nervous about a speech. Consider each of them individually. What's the worst that could happen in each case? If it happens, what will you do? For instance, if you're scared that you'll forget what to say next, think, "I'll just pause and look at my notes."
Exercise before a speech. Running and other forms of violent movement can use up your extra adrenaline（肾上腺素）. Try taking a jog, going for a rapid bike ride, or even dancing out your nerves on the morning before you present.5.
A.Practice there if you can
B.List the things that you're afraid of.
C.Make notes of the key points of your speech
D.Get more chance to practice before small groups.
E.Here are some tips that might help reduce anxiety.
F.Below are four causes of anxiety before the speech.
G.If you can't do something violent，take a walk instead.

Last summer, we went to work on the farm of my grandma. Upon arrival, we were divided into group of four, each group sharing one room. We worked quickly and hardly, sweeping the floor and made the bed. Then, we went to the yard, began to work at once and helped the corn harvest. We cut the corns off and pile them up. Never in my life had I ever seen so much corns lying in the field. I felt it was a great fun. On the last day, we gathered in the open air to have a party, where we sang songs but danced happily. How an unforgettable experience for both of us.
