Smartphones store a lot of personal data. These devices know our names,the names of our friends，our addresses and where we are right now.1. A weather app needs to know where a person is to report the local forecast，for example.

Many smartphone apps don't cost anything to download and use.But don't be fooled. There's still a price. 2. Those same apps may often send data on to advertisers as well.Those advertisers will pay well to know how people behave and live.Once your data leave a device，you can't get them back. And that data theft may not be harmless. Moreover，those data may tell when someone leaves home and when he gets back. 3. Social media sites often have access to a user's images and posts.

Recently a new online tool has been developed to track the misuse of private data.4. It tells people when their apps are sending data，which can help spot the misuse. SPEProxy identifies the misuse of data using an approach that has already been used to diagnose illnesses.

In the clinical field，a kind of medical software is used to collect data from a patient. Then it compares them to those symptoms of many possible illnesses to make a diagnosis.

Right now，people can only track data with the new tool by going to a website.5. It's also a bit awkward to use.People may not want to go to the trouble of getting online to track their data. A more convenient version that people could install on their phones is in urgent need.

A．It is called SPEProxy.

B．That means it's limited.

C. It is more than convenient to use in computers.

D．Your privacy is what's paying for it.

E．Some apps use those data to do their job.

F．Some apps may charge you much money to operate.

G．They can show how and where people spend their days.

Dear Malia and Sasha,

I know that you’ve both had a lot of fun these last two years on the campaign trail, going to picnics and parades and state fairs, eating all sorts of junk food your mother and I probably shouldn’t have let you have. But I also know that it hasn’t always been easy for you and Mom, and that as excited as you both are about that new puppy, it doesn’t make up for all the time we’ve been apart. I know how much I’ve missed these past two years, and today I want to tell you a little more about why I decided to take our family on this journey.

When I was a young man, I thought life was all about me-about how I’d make my way in the world, become successful, and get the things I want. But then the two of you came into my world with all your curiosity and mischief and those smiles that never fail to fill my heart and light up my day. And suddenly, all my big plans for myself didn’t seem so important anymore. I soon found that the greatest joy in my life was the joy I saw in yours. And I realized that my own life wouldn’t count for much unless I was able to ensure that you had every opportunity for happiness and fulfillment in yours. In the end, girls, that’s why I ran for President: because of what I want for you and for every child in this nation.

I want all our children to go to schools worthy of their potential—schools that challenge them, inspire them, and instill in them a sense of wonder about the world around them. I want them to have the chance to go to college-even if their parents aren’t rich. And I want them to get good jobs: jobs that pay well and give them benefits like health care, jobs that let them spend time with their own kids and retire with dignity.

I want us to push the boundaries of discovery so that you’ll live to see new technologies and inventions that improve our lives and make our planet cleaner and safer. And I want us to push our own human boundaries to reach beyond the divides of race and region, gender and religion that keep us from seeing the best in each other.

Sometimes we have to send our young men and women into war and other dangerous situations to protect our country—but when we do, I want to make sure that it is only for a very good reason, that we try our best to settle our differences with others peacefully, and that we do everything possible to keep our servicemen and women safe. And I want every child to understand that the blessings these brave Americans fight for are not free—that with the great privilege of being a citizen of this nation comes great responsibility.

That was the lesson your grandmother tried to teach me when I was your age, reading me the opening lines of the Declaration of Independence and telling me about the men and women who marched for equality because they believed those words put to paper two centuries ago should mean something.

She helped me understand that America is great not because it is perfect but because it can always be made better-and that the unfinished work of perfecting our union falls to each of us. It’s a charge we pass on to our children, coming closer with each new generation to what we know America should be.

I hope both of you will take up that work, righting the wrongs that you see and working to give others the chances you’ve had. Not just because you have an obligation to give something back to this country that has given our family so much—although you do have that obligation. But because you have an obligation to yourself. Because it is only when you hitch your wagon to something larger than yourself that you will realize your true potential.

These are the things I want for you-to grow up in a world with no limits on your dreams and no achievements beyond your reach, and to grow into compassionate, committed women who will help build that world. And I want every child to have the same chances to learn and dream and grow and thrive that you girls have. That’s why I’ve taken our family on this great adventure.

I am so proud of both of you. I love you more than you can ever know. And I am grateful every day for your patience, poise, grace, and humor as we prepare to start our new life together in the White House.

Love, Dad

We all know cameras. But have you heard of Google’s new camera? It is a small, smart device, called Clips. It comes with a case that has a clip (夹子), but it’s not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smart phone.

Onboard the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there’s a face you see frequently, it’ll try to get nice photos of those faces,” said Juston Payne, the device’s product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot—like when a child’s hand is over the lens, or if it is tossed in a dark purse.

The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

Did people think it was strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that the device is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

“This product is only possible because of the way that technology has advanced,” Payne said. It was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we’re likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

1.What is the most outstanding feature of Clips?

A. It is equipped with tough glass.

B. It enables easy Internet access.

C. It allows of hands-free photography.

D. It can be worn on your clothing.

2.What does the underlined word “candid” in Paragraph 2 probably mean?

A. Brief.　　 B. Touching.

C. Unforgettable.　　 D. Embarrassing.

3.What makes Clips a reality according to Juston Payne?

A. The popularity of the Internet.

B. The advance in technology.

C. The rise of the smart phone industry.

D. The reduction in the price of lens.

4.What is the best title for the text?

A. An Alternative Way to Photograph

B. New Gadgets in the Age of Apps

C. Artificial Intelligence in Everyday Life

D. A New Digital Camera from Google

In a certain store where they sell puddings, a number of these delicious things are laid out in a row during the Christmas season. Here you may select the one which is most to your taste, and you are even allowed to sample them before coming to a decision.

I have often wondered whether some people, who had no intention of making a purchase, would take advantage of this privilege. One day I asked this question of the shop girl, and I learned it was indeed the case. “Now there’s one old gentleman, for instance,” she told me, “he comes here almost every week and samples each one of the puddings, though he never buys anything, and I suspect he never will. I remember him from last year and the year before that, too. Well, let him come if he wants it, and welcome to it. And what’s more, I hope there are a lot more stores where he can go and get his share. He looks as if he needed it all right, and I suppose they can afford it.”

She was still speaking when an elderly gentleman limped up to the counter and began looking closely at the row of puddings with great interest. “Why, that’s the very gentleman I’ve been telling you about,” whispered the shop girl. “Just watch him now.” And then turning to him: “Would you like to sample them, sir? Here’s a spoon for you to use. “The elderly gentleman, who was poorly but neatly dressed, accepted the spoon and began eagerly to sample one after another of the puddings, only breaking off occasionally to wipe his red eyes with a large torn handkerchief. “This is quite good”. “This is not bad either, but a little too heavy”. All the time it was quite evident that he sincerely believed that he might eventually buy one of these puddings, and I am positive that he did not for a moment feel that he was in any way cheating the store. Poor old chap! Probably he had come down in the world and this sampling was all that was left him from the time when he could afford to come and select his favorite pudding.

Amidst the crowd of happy, prosperous looking Christmas shoppers, the little black figure of the old man seemed pitiful and out of place, and in a burst of benevolence, I went up to him and said:

“Pardon me, sir, will you do me a favor? Let me purchase you one of these puddings. It would give me such pleasure.”

He jumped back as if he had been stung, and the blood rushed into his wrinkled face.

“Excuse me,” he said, with more dignity than I would have thought possible considering his appearance, “I do not believe I have the pleasure of knowing you. Undoubtedly you have mistaken me for someone else.” And with a quick decision he turned to the shop girl and said in a loud voice, “Kindly pack me up this one here. I will take it with me.” He pointed at one of the largest and most expensive of the puddings.

The girl took down the pudding from its stand and started to make a parcel of it, While he pulled out a worn little black pocketbook and began counting out shillings and pennies on to the counter. To save his “honor”, he had been forced into a purchase which he could not possibly afford. How I longed for the power to unsay my tactless words! It was too late though, and I felt that the kindest thing I could do now would be walk away.

“You pay at the desk,” the shop girl was telling him, but he did not seem to understand and kept trying to put the coins into her hand. And that was the last I saw or heard of the old man. Now he can never go there to sample puddings and more.

1.By saying it was indeed the case. , the author meant that ______.

A. many shoppers would sample pudding before buying them

B. some people just sampled pudding but didn’t buy them

D. worked in the shop for a few months

3.The old man finally bought a pudding because ______

B. the author gave him some money

C. he was annoyed by the author’s offer

D. the shop girl asked him to purchase one

4.Why did the author feel that he should walk away according to the passage ?

A. He had something urgent to do

B.He was quite angry with the old man

They crossed in front of me as I was driving out of the store parking lot. My first reaction was anger at being delayed for a whole ten seconds. I quickly became patient when I realised that this was an elderly couple.

The man leaned on his wife who walked in front of him. He not only used her for support but it was obvious that he was blind. The two of them worked as one---each needing the other to function in this fast-changing world.

That little example of true strength changed my whole personal perception(理解) of life that day. Suddenly I wasn’t so mad about having to work a few extra hours on Saturdays. I had my strength, and I was still relatively young.

That picture of those two elderly people walking with dignity and strength stayed with me the entire week. My life wasn’t so bad after all. I had my health and a good job. I had a wonderful, supportive wife. I started to think---not only was I lucky to have it all, but so was that wonderful old couple, who, despite the trials and sufferings of a long life, still had the love and support of each other to carry them through this world.

There are so many people out there just like that couple. My wife and I sometimes picture ourselves in our old age, walking arm-in-arm into the sunset. That image always gives us a warm feeling of comfort. Just remember, none of us would be here if it wasn’t for our elders. We should all have a little extra time and patience when it comes to helping our elder friends.

1.When the author was about to drive away, the couple __________________.

2. After he saw the couple, the author would _________________.

3. What did the author think of the couple?

4. From the passage, we learn _______________________.
