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.
Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you’ll have no trouble answering these questions.
Most of us observed much more as children than we do as adults. A child’s day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的) to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.
The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they’d felt cold water at first.
Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.
The pressures of "time" and "destination"（目的地）are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what’s around them. I asked them what they’d seen. "Oh, a few birds," they said. They seemed bent on their destinations.
Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations(感觉）. Wander in this frame of mind and you will open a new dimension to your life.

A qualified doctor who rarely practised but instead devoted his life to writing. He once said, “Medicine is my lawful wife and literature is my lover.”Russian writer Anton Pavlovich Chekhov was a great playwright(剧作家) and one of the masters of the modern short story.
When Clekhov entered the Moscow University Medical School in 1879,he started to publish hundreds of comic short stories to support his family. After he graduated, he wrote regularly for a local daily newspaper.
As a writer he was extremely fast,often producing a short story in an hour or less. Checkhov’s medical and science experience can be seen through the indifference many of his characters show to tragic(悲剧的) events. In 1892,he became a full-time writer and published some of his most memorable stories.
Chekhov often wrote about the sufferings of life in small towns of Russia. Tragic events controlled his characters who were filled with feelings of hopelessness and despair.
It is often said that nothing happens in Chekhov’s stories and plays.He made up for this with his exciting technique for developing drama within his characters. Chekhov’s works combined the calm attitude of a scientist and doctor with the sensitivity of an artist.
Some of Chekhov’s works were translated into Chinese as early as the 1940s.One of his famous stories,“The Man in a Shell ”，about a school teacher’s extraordinarily orderly life was selected as a text for Chinese senior students.

The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.
Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.
There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked, their power to destroy is set free.”
There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.
Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.
Honesty and openness is important: it proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.
Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

B.people are used to exposing their weaknesses
C.people sometimes have no courage to share their stories
D.some stories make themselves feel sad

A.be open to people close to you by sharing some secrets
B.share stories appropriately for the good of others and ourselves

Food Parts You Should Never Throw Away in the Garbage
Pineapple Core
When you carve out the core of a pineapple, don't throw it in the garbage. You can use the pineapple core for all kinds of recipes, and there are tons of vitamins and minerals hiding within. To use the pineapple core: chop it and add it to fruit salad, blend it into smoothies, cut it into cubes and freeze for later use, or simply add it to water or even tea to improve flavor.
Kiwi Skin
If you never thought you could eat kiwi in the way you eat a peach, think again. That skin really is good for you and contains a lot of vitamin C, and in fact, it's also higher in fiber than the rest of the fruit. Of course, that rough, ugly skin isn't for everyone, so if you don't like it, try adding a whole kiwi to a smoothie to hide the taste of the skin.
Banana Peel
Most of us eat the banana without giving the soft peel a second thought. Here's why that's a mistake: banana peel contains tryptophan(色氨酸), which increases "the happiness hormone" to help with mood regulation and nerve system. There are a few creative ways to use the peel. Cook or boil for at least 10 minutes to soften. You can add it to smoothies, stir-fries, or soups. And, for a treat, simply slice and bake a banana with the skin on.
Watermelon Skin and Seed
The delicious, red inside makes for a refreshing snack or juice, but you're able to get some powerful nutrients in the skin and seeds as well. Cut out the white part under the green outside and use it in your cooking. It has vitamin C and B6, to keep you healthy. As for the seeds, you can roast them in the oven. Then add them to salads or to nut snacks.
1.Which of the following has a larger amount of fiber than its other parts?
A.Pineapple cores.
