Do you often lose things? Don’t worry. Now a new tool, which can be connected to any object you might lose, may be the way to solve your problem. The Tile, a small square linked up to your iphone or ipad by means of Bluetooth, lets you see how close you are to your missing item, within a 50-to-150-foot range (范围). If the item goes out of your phone’s 150-foot range, it can still be found on other smart phones with the same app.

When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object — a dog, for example, or a stolen bike — go out of your own phone’s 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.

Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn’t to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads.

1.What can the Tile app help you?

A. To find other phone users.

B. To find your missing items.

C. To save your phone’s power.

2.What does the second paragraph mainly tell us?

A. What the Tile app is.

B. How the Tile app works.

C. Why the Tile app was created.

D. What the advantages of the Tile app are.

3.What can we learn from the passage?

B. One smart phone can only be linked up with one Tile.

C. The Tile can’t be linked up with a phone without Bluetooth.

D. A missing item can’t be found if it goes out of your phone’s Bluetooth range.

4.Where does the passage probably come from?

Kanda really doesn't like to walk alone. The scientist from a research institute of intelligent robots finds the experience so boring that he'd rather drive—even though he lives close to his lab and knows that walking us healthy. "I enjoy walking with someone, like with my wife, with my daughter," Kanda said. "But they are not always available."

So Kanda, who specializes in human-like bots, developed a robotic walking partner that could make small talk based on its surroundings, which, he hopes, might motivate people to get out and exercise more. The bot rests on a person's shoulder like a boxy parrot. It weighs about a pound and a half and sits roughly 8.5 inches high, 3.5inches wide, and 10 inches long. A microphone, speaker, and internal camera allow it to communicate. It's even equipped with a smile.

Kanda and his team collected video form five different locations, including a garden and a shopping mall, and created a dataset of small talk topics related to each location. Then they programmed the robot to associate visual cues with specific topics. A special speech software provided the robot with a voice. Near a group of parked cars, for example, it might say, "In a big parking lot, sometimes I forget where I parked."

They tested the robot on 15 volunteers, 10 males and 5 females, who were paid and averaged about 26 years old. "Have you ever blown a puff of dandelion(蒲公英)seeds into the air?" The robot asked a participant, who smiled and responded, "Yes, I often did that when I was a child." Although several participants noted the robot's weight, Kanda was surprised that no one considered the experience as strange or funny. "I guess people enjoy new technologies," he said.

Just like a human partner, Kanda's bot isn't perfect. It's not able to go for walks in heavy rain and, while the robot can make expressions, it can't really hold a conversation, about which Kanda is most worried. Despite its limits, Kanda was comforted by the bot's presence. "I felt a kind of sense of being with someone, "he said, "particularly when it spoke."

1.Why does Kanda have the idea of developing a robotic walking partner?

A. Because he wants someone to accompany him while walking.

B. Because he has never developed a robot like a parrot.

C. Because his family are unwilling to walk with him.

D. Because he is crazy about developing robots.

2.What characteristic does the robot have?

A. It can "speak" and "see".

B. It can walk like a human being.

C. It can communicate with people freely.

D. It is much more humorous than a real person.

3.What is necessary for the robot to function?

A. A small size.

B. A boxy shape.

C. A human partner.

D. A speech software.

4.What is Kanda most likely to do about his robot next?

A. To make it more convenient to carry.

B. To improve its conversational skills.

C. To enable it to walk in heavy rain.

D. To better its sound system.

At thirteen,I was diagnosed with kind of attention disorder.It made school difficult for me.When people else in the class was focusing on tasks,I could not.

The American Bystander

On a humid subway ride into work a few days ago, a woman on the other end of my car had a seizure (病情突然发作). All of a sudden, I heard her let out a painful sigh as she collapsed. For several minutes, the train continued down the track, and everyone in the car just stared at the woman. Finally, at the next stop a man informed the operator of what had happened and called 911. Luckily the woman came to herself as the EMTs carried her off the train. Ever since, I’ve been puzzled by the same question — why didn’t anyone do anything? And more importantly, why didn’t I do anything?

We’ve learned about the commonly referenced bystander effect—a psychological phenomenon in which individuals will avoid offering help to a person in need when other people are present. The bystander effect is attributed to two different psychological processes: social influence—individuals in a group will monitor and imitate other group members’ behavior—and shift of responsibility—individuals will cease to help because they believe that someone else will.

Even though most people probably haven’t witnessed a woman having a seizure on the subway, I’m sure if asked, anyone could think of a time when they could have helped and simply didn’t. In fact, I know that we have all experienced the bystander effect, because I believe it is one of American society’s most common headaches.

Anyone who follows the news can tell you that most of what we hear or read about these days is another death or another hate crime committed right in our own country. Consider the most recent theatre shooting in Nashville. The headlines read Another Theatre Shooting, Gunman is dead. When we read that headline or heard it on the news, most of us just acknowledged how sad it was, then told ourselves that there is nothing we can do to help and assumed that someone else would.

If America is just one large group of witnesses, all while telling ourselves that someone else most certainly will step in, how can we hope to shake the hold of this social psychological spell? The solution lies solely within us, to know the difference between doing what is justifiable and doing what is right, helping those in need when we have the means and opportunity to do so.

I want to be like the man on the subway who told the operator about the woman’s seizure, because as soon as he did, people followed suit and offered help. We have the power to choose whether to justify passivity or actively decide to do the right thing, and as a society I believe we ought to break free from our psychological tendency to just stand by.

1.What was the most passengers’ attitude towards the woman’s seizure?

A. Indifferent. B. Skeptical.

C. Enthusiastic. D. Concerned.

2.The psychological explanation for the fact that most people hesitate to help is that ________.

A. they need heroes or good examples to learn from

B. they believe such cases are none of their business

C. they fear that their behavior will be imitated by others

D. they count on other group members to give a helping hand

3.What can we learn from the theatre shooting in Nashville?

A. The mass media are only too concerned about crimes and deaths.

B. The majority of the US citizens are suffering from crimes.

C. People get too accustomed to pay adequate attention to crimes.

D. Media coverage is inconsistent with what the Americans assume.

4.As far as the author is concerned, the key to solving such an effect lies in ________.

A. the necessary means and opportunity to help others

B. the essential power to display psychological tendency

C. the acute awareness of making a right choice

D. the determined effort to help whoever is in need of help
