University graduates Mallorie Brodie and Lauren Hasegawa, who invented a smartphone app that tracks construction defects for commercial builders, had a tiger by the tail.

Bridgit, which they founded in 2012, launched a cloud-based communications platform that helped manage defects on construction sites, which can delay projects and result in costly repairs if left unchecked. The smartphone application lets site supervisors take photos of cracks or damaged paint, share them with employees and track the problems to solution.

More than 600 subcontractors used the pilot version in many building sites before the commercial version, called Closeout, officially launched.

Feedback(反饋)was so good that they began to wonder: Why limit their invention to a specific industry? Why not turn it into some kind of a handy tool for consumers too? This became their dilemma. In other words, should they stay the course or look for wider applications of their app?

The experts polled all agreed Bridgit should stay focused on its original goal. Ms. Hasegawa and Ms. Brodie took that advice.

As more business customers signed on, it became clear that they made the right decision. Since then, the company’s growth has been rapid.

Earlier this year, Bridgit launched Closeout, which is designed so that even the least tech-savvy can use it easily. Today, the app is being used on sites across Canada and the United States and even by top general contractors.

In October, Bridgit was named to the Canadian Innovation Exchange’s top 20 list of Canada’s most innovative (創(chuàng)新的) companies working in digital media and information and communication technology .

But Ms. Hasegawa and Ms. Brodie are not resting on their glories. They have also been collecting feedback on Closeout from customers, and they’ll launch a new version in the spring. It will target not only general contractors but developers and building owners, too.

1.What does the underlined word ＂defects＂ in Paragraph 1 probably mean?

A. Style. B. Process.

C. Drawback. D. Material.

2.What did the two graduates decide to do when the pilot version was well received?

A. Turn to the ordinary consumer market.

B. Look for wider applications of their app.

C. Turn it into a widely-used tool for consumers.

D. Continue centering on the development in construction industry.

3.Who could be their potential customers?

A. Smartphone users. B. Architects.

C. Computer programmers. D. Photographers.

4.Which of the following might be the best title?

A. Graduates’ smartphone application takes off

B. Graduates’ smartphone application has a bright future

C. Graduates’ smartphone application meets with challenges

D. Graduates’ smartphone application plays an important role in our life

A British friend told me he couldn’t understand why Chinese people love eating sunflower seeds as a snack so much “I’ve met a lot of older Chinese and many have a crack in their front teeth; I believe that’s from cracking the seeds,” he said.

I had never noticed the habit, but once he mentioned it, I suddenly became more aware. I realized that whenever I’m watching TV or typing a report, I always start mindlessly cracking sunflower seeds. My friend doesn’t like sunflower seeds, and, to him, it seems unnecessary to work so much just to get one small seed.

When we were young, the whole family would usually get together for Chinese New Year. Then, we all lived close to one another, usually in a small city, and sometime even neighbors would go door-to-door on Chinese New Year’s Eve to check out what every household was making.

I remember my parents would be in the kitchen cooking. Out in the living room , a large table would already be laid out, complete with fancy tablecloth, ready-made dumping fillings, and dishes full of candy, fruits and sunflower seeds.

Some of the dishes were to be offered to our ancestors later, while others were for neighbors and children to eat be-fore the evening feast. I must have learned how to crack sunflower seeds back then.

I don’t think it’s right to criticize one’s choice in food or eating habits, no matter how strange they may seem.

It’s not only in China. When I went abroad, I found people had all sorts of strange habits when it came to food. In Denmark, they put salted red fish on bread and eat it for dinner, no matter how much it ruins your breath. They think it’s a delicacy, and it’s connected to their culture. I think it’s a wonderful tradition.

1.What did the writer become aware of?

A. She had ever typed a report about seeds.

B. She are various snacks while watching TV.

C. She had a habit of cracking sunflower seeds.

D. She damaged her teeth by eating sunflower seeds.

2.What does the writer prove by mentioning Chinese New Year?

A. The traditions of celebrating it disappear.

B. Children can eat delicious food on that day

C. The families get together for it.

D. Eating sunflower seeds is related to it.

3.The writer’s to Denmark’s way of eating bread is______.

A. acceptable B. critical

C. neutral D. doubtful

4.What lesson can we learn from the story?

A. One kind of food doesn’t necessarily suit everyone.

B. Eating habits come from a certain culture.

C. It is good to form healthy eating habits.

D. Changing your eating habits will change your life.

Some people think if you are happy, you are blind to reality. But when we research it, happiness actually raises every single business and educational outcome for the brain. How did we miss this? Why do we have these social misunderstandings about happiness? Because we assumed you were average. When we study people, scientists are often interested in what the average is.

Many people think happiness is genetic. That’s only half the story, because the average person does not fight their genes. When we stop studying the average and begin researching positive outliers —people who are above average for a positive aspect like optimism or intelligence —a wildly different picture appears. Our daily decisions and habits have a huge impact upon both our levels of happiness and success.

Scientifically, happiness is a choice. It is a choice about where your single processor brain will devote its limited resources as you process the world. If you scan for the negative first, your brain really has no resources left over to see the things you are grateful for or the meaning embedded(嵌入) in your work. But if you scan the world for the positive, you start to acquire an amazing advantage.

I wrote the cover story for the Harvard Business Review magazine on “Happiness Leads to Profits.” Based on my article called “Positive Intelligence” and my research in The Happiness Advantage, I summarized our researched conclusion: the single greatest advantage in the modern economy is a happy and busy workforce.

A decade of research in the business world proves that happiness raises nearly every business and educational outcome: increasing sales by 37%, productivity by 31%, and accuracy on tasks by 19%, as well as a number of health and quality-of-life improvements.

1.The underlined word “this” in the first paragraph refers to .

A. the fact that people are happy

B. the connection between happiness and educational outcome

C. the fact that people often misunderstand happiness

D. the fact that most people are average

2.What can we learn from the passage?

A. Scientists are only interested in what the average is.

B. You can choose to be happy or not.

C. The average are not happy at all.

D. Our decisions and habits have nothing to do with happiness.

3.Why does the writer mention his articles and research?

A. To advertise himself.

B. To arouse the readers’ interest.

C. To support his point about happiness.

D. To attract the readers to read his articles.

4.What is the author’s purpose of writing this article?

A. To explain what is happiness.

B. To describe the misunderstandings about happiness.

C. To show people the importance of happiness.

D. To make the point that happiness promotes business and educational outcome.

Punctuation (標點) Is for Clarity

When you talk, you do not depend upon words alone to tell your listener what you mean. 1. You shrug a shoulder, raise an eyebrow, clasp hands, bend forward or backward, stamp your foot, nod or shake your head. These body languages may vary from culture to culture but they do help the speakers to convey meanings. 2. You yell or whisper; speak calmly or angrily; lower or raise your voice at the end of a statement or a question. Meaning in talk is also affected by pauses and silence, which are often as significant as words themselves. 3.

Similarly, when we write, we cannot expect words alone to make clear to our reader what we have in mind. The pauses, stresses and gestures which occur in speech must be represented in writing by various marks of punctuation if meaning is to be fully clear. 4.

Punctuation came into existence only for the purpose of making clear the meaning of writing words. Every mark of punctuation is a sort of road sign provided to help the reader along his way.5. It is harmful or ineffective if it interrupts the flow of thought from your mind to that of your readers.

A. Each of us has probably seen a skilled actor convey ideas and moods without using any words at all.

B. The practice of punctuation, however, has been changing in the last two centuries.

C. Facial and body gestures can and do add much to the words themselves.

D. The needs of the eye are quite different from those of the ear.

E. Additionally, the tones and stress of your voice can and do influence the meanings of words you speak.

F. Punctuation began to become standard in the middle of the 19th century.

G. Punctuation is effective if it helps the reader to understand.
