【题目】 Suppose that we lined up our roughly 14 million United States businesses in order of size, starting with the smallest, along an imaginary road from San Francisco to New York. There will be 4,500 businesses to the mile, or a little less than one per foot. Suppose further that we planted a flag each business. The height of the flag pole represents the yearly volume of sales (销量) , each $ 10, 000 in sales in shown by one foot of pole.

The line of flagpoles is a very interesting sight. From San Francisco to about Reno, it is almost unnoticeable, a row of poles about a foot high. From Reno eastward the poles increase in height until, near Columbus, Ohio - about four - fifths of the way across the nation - flags fly about 10 feet in the air.

But as we approach the eastern terminus (终点) , the poles suddenly begin to mount (升高) . There are about 300, 000 firms in the country with sales over $ 500, 000. These firms take up the last 75 miles of the 3,000 - mile road. There are 200, 000 firms with sales over $ 1 million. They take up the last 50 miles. Then there are 1, 000 firms with sales of $ 50, 000, 000 or more. They take up the last quarter of a mile before the city limits, flags flying at cloud height, 5 , 000 feet up .

At the very gate of New York, on the last 100 feet of the last mile , we find the 100 largest industrial firms . They have sales of at least $ 1.5 billion, so that their flags are already miles high. Along the last 10 feet of road , there are 10 largest companies . Their sales are roughly $ 10 billion and up : their flags fly 190 miles in the air , almost in the stratosphere (平流层) .

【题目】New App Helps People Remember Faces

Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people’s names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.

The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody,” says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.

After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee’s face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users’ data after an event.

Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you.”

The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone’s face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user’s phone, according to the team behind the app.

1SocialRecall is used to ________.

A. take photosB. identify people

C. organize eventsD. make friends

2Paragraph 3 is mainly about ________.

A. how the app works

B. how the app was created

C. what makes the app popular

3SocialRecall helps people with prosopagnosia by ________.

A. giving names to the photos kept in their smartphones

B. collecting information previously entered in the phone

C. providing the information of a person when they first meet

D. showing the person’s information when it spots a stored face

4What can we learn about SocialRecall from the passage?

A. It may put people’s privacy at risk.

B. It has caused unintended consequences.

C. It can prevent some communication disorders.

D. It is praised by users for its protective measures.

【题目】Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

It was 1that students did not write details of how they arrived at their answers or conclusions. I decided to help students write in more detail about what they were thinking when they solved their problems or when they wrote about their ideas.

I chose a common, everyday task that all of us 2 in: choosing what to wear. When I asked them how they decided what they wore that day, there was a(n) 3 moment of silence. It seemed a 4 silly question. A few just said “they wore what they wore.” This was a perfect beginning as it was the same kind of response they were giving as to how they were getting their math answers. I told them how I decided what I wore that day.

First I checked the weather in the paper and by looking outside. I had to decide between wearing a dress or skirt since either one could make a difference in the 5 I wish to give. Most of the girls related to this one. I had to be sure what I wanted to wear was clean and ironed. They 6 no one ironed clothes any more. I had to check to see if I had shoes that went with the possible outfit. I thought about what I had worn 7 as I usually don’t wear the same clothes in the same week. I thought about the color I felt like wearing. I thought about the 8 I would be doing that day both at school and after school.

Each new consideration brought out comments from the students. I could expand on each or just mention it and go on, 9 on how long I wanted the lesson to go. After this discussion, it was clear to students that their thinking process is richer than they first suspected. It was a good lesson for showing details of the thinking process of which we weren’t 10.
