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

Most people say that they do not usually feel confident. But exciting things can happen when we actually believe in ourselves. Here is a man who believed in his own ability even as a boy, and that confidence helped shape his adult life.

At the turn of the last century, a young boy quit school to help with the family expenses. When he was fifteen, he became interested in automobiles(汽車) and worked in a garage. He subscribed to a correspondence course on automobiles and, after a long day in the garage, studied at the kitchen table in the lamplight.

When he felt ready, he walked into the Frayer-Miller Automobile Company of Columbus, Ohio. When Mr. Frayer noticed him, he asked, “Well, what do you want?”

“I just thought I’d tell you I’m coming to work here tomorrow morning,” the boy replied. 

“Oh! Who hired you?”

“Nobody yet, but I’ll be on the job in the morning. If I’m not worth anything, you can fire me.”

Early the next morning the boy returned to the plant. Noticing the floor was thick with metal shavings and accumulated dirt, the boy got a broom and set out to clean the place.

Because of his self-confidence and work ethic, the boy’s future was predictable. He went on to stand out in many fields, including automobile racing, piloting World War I planes and founding one of America’s largest airline companies ---- Eastern Airlines.

People who become more confident habitually encourage themselves. Without confidence, we are not likely to move far in the direction of our dreams. It is important that we always believe in ourselves. In order to reach victory, we must believe in ourselves even when we make mistakes

1.How did the boy learn knowledge concerning automobiles?

A. He attended school in the daytime.

B. He studied hard at home.

C. He read books in the garage where he worked.

D. He turned to some instructors for help.

2.We can learn from the boy’s words that _____.

A. he wanted to show off his competence

B. he looked down upon others

C. he was very generous

D. he believed in himself

3.Due to his efforts and confidence, the boy _____.

A. made World War I planes

B. learned much knowledge in a garage

C. achieved everything in his life

D. set up Eastern Airlines

4.What is the purpose of the passage?

A. To inspire us with self-confidence.

B. To tell us an interesting story.

C. To inspire us to work hard.

D. To stress the importance of realizing our dreams.

If you are a motivated person, it is easy to put your personal goals ahead of those of the people around you. It is natural and not necessarily a bad thing. However, it is crucial t learn to be a team player. Acting as a part of a team builds character, teacher empathy （共鳴）, and eventually achieves goals.1.Here’s why:

Group Effort Is More Effective than Individual Effort. You can run a small business pretty independently, but if you ever plan on being employed or running a business that employs others, you’ll have to learn how to work with other people.2.

Improving Others Equals Improving Yourself. If you’re on a team, your personal success helps make you a good team player. This is because most people are at least a little bit competitive, whether they admit it or not. When you do well, you set a standard that others will want to meet. By pushing yourself, you help push the people on your team.3.When you see someone you’re working with do something better than you, more often than not, you’ll push yourself to meet that standard.

Your Attitude Matters4. People respect the ability to work well with others more than anything. Your individual actions have an impact, but if you’re reluctant to do something to help your team, it’ll be evident and your contribution will be less appreciated. Having a genuine interest in your team helps you as well as those you’re working with.

5.As much as your work is important and necessary to the success of your team, the success of your team is important and necessary to your success.

A. Of course, this works both ways

B. These is a mutual（相互的）effect between personal success and team achievement

C. People with team spirit try hard to make their team the best of all

D. You should be the kind of person who wants to be a team player

E. Those who show respect for others will be respected in turn

F. All of these things, in turn, contribute to your personal success

G. The most impressive achievements are accomplished by groups of people, not individuals

Yuoki, a restaurant in Germany, is not your everyday all-you-can-eat buffet (自助餐）. For starters, there isn't an actual buffet to fill your plate. Instead, customers are seated at a table and provided with iPads which they can use to order up to five small dishes every ten minutes. They can eat as much as they want for 120 minutes, but having the food served at short intervals (間隔) allows diners to constantly assess how hungry they are and order accordingly, preventing food waste. Also, the owner, Luan Guoyu, believes, “our eyes are bigger than our stomach”, so not being able to see the cooked food at the buffet prevents people from ordering more food than they can actually eat.

But Luan Guoyu's most effective way of fighting food waste, and the one that has attracted media attention, is his ?1 ($1.15) fine for food still left on the plate. “It’s called ‘ all-you-can-eat’ ” he says, adding that the extra charge is not meant to increase his income, but to act as a warning against wasting food.

Luan Guoyu's system is unique in the state of Baden-Wurttemberg, but not in Germany. Okinii, a Japanese-style restaurant in Dusseldorf, has also been charging customer, the same ? 1 tax for unfinished food on their plates since 2013.

With so many people living on the edge of their nations, and food waste becoming a serious problem in developed countries, it will be interesting to see if more restaurants will start carrying out the “eat up or pay up” policy. Even if they give the money from this fine to charity, it would still help them to save money in dealing with waste, so it's a win for everyone.

1.What does the underlined word “assess” in Paragraph 1 probably mean?

A. Doubt. B. Realize.

C. Judge. D. Compare.

2.What will Luan Guoyu do when people can’t finish the food on their plates?

A. He will charge them extra money.

B. He will advise them to eat up the food.

C. He will ask them to take the food away.

D. He will warn them to order less food next time.

3.What is the text mainly about?

A. Various German restaurants.

B. The seriousness of food waste.

C. Secrets of managing a restaurant.

D. Special ways to fight food waste.

4.What does the author think of the “eat up or pay up” policy?

A. Unfair. B. Funny.

C. Reasonable. D. Doubtful.
