People are being lured(引诱)onto Facebook with the promise of a fun and free service without realizing they’re paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook, because people don’t really know what their personal details are worth.
The biggest problem, however, is that the company keeps changing the rules. Early on, you could keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends’ names—were set, by default(默认), to be shared with everyone on the Internet.
According to Facebook’s vice-- president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience.”
Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they’re online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Commission to set guidelines for social-networking sites. “I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy, it’s only the beginning, which is why I’m considering deactivating(撤销)my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That is too high a price to pay.
1.What do we learn about Facebook from the first paragraph?

高二英语阅读理解中等难度题查看答案及解析
More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night’s sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends.
Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen.
Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, “Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed.”
They wrote in the journal Applied Ergonomics(应用人类工程学) that iPad makers should adjust the spectral power distribution(光谱功率分布) of the devices so that they affect the sleep patterns of users less.
It is not just a good night’s sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.
1.Blue light prevents iPad users from sleeping well because ____.
A. it is the same as daylight which keeps people awake
B. it makes the brain more active
C. it is brighter than light that is more orange or red
D. it can help decrease the production of melatonin
2.The underlined phrase “dim the display” means ____.
A. keep away from the display
B. make the display less bright
C. clean the display carefully
D. turn off the display
3. In the last paragraph, the author intends to ____.
A. warn of the seriousness of long-term poor sleep
B. call on researchers to study sleep patterns
C. show the danger of obesity and cancers
D. show how sleep is harmed by using iPads too much
4.What’s the main idea of the passage?
A. Scientists are warning that blue light is bad for our health.
B. People should limit the use of electronic devices
C. Using iPads before bed can cause a poor night’s sleep.
D. Looking at screens of iPads increase chances of sleeplessness.

Millions of people nowadays use Facebook, Instagram and Snapchat to converse with their friends. They use Skype to bridge long distances and Twitter to interact with public figure. But as more of our lives move online, are Internet-based interactions sufficient for a fulfilling life?
There have been considerable warnings about the drawbacks of online interactions. Some scholars have realized that our devotion to the screens is detracting from face-to-face conversations. For instance, a study showed that children who had been spending time with television and computers for a long period of time were significantly worse at recognizing nonverbal(非语言的)psychological suggestions in a conversation than those who had just five days without screens.
But there is another side to the argument: A 2015 Pew Foundation report found that teenagers use online interactions to strengthen their friendships. Plus, 57% of teenagers reported that they’d made friends online. Amori Milkami, a psychology professor at the University of British Columbia, has conducted several studies on online interactions and tells that the nature of online communication is changing as young people treat social networks in an entirely different ways.
Too much research tends to mix all online interactions together, she says, instead of distinguishing between positive, meaning conversations and more superficial, negative exchanges. According to her, online communities can be especially useful for people who have an unusual concern and live in isolated areas, and so are unlikely to meet people with similar concerns in person.
“The major good aspect of online interactions compared to in-person ones is that social network allow users to interact with so many people at once. Whether or not that’s positive or negative depends on the type of friends you have. It’s possible to get the same level of achievement from online interactions as it is from in=person friends,” says Mikami. “This might be hard for older adults to believe and it might not be possible for them, because they might not feel comfortable having those kinds of deep online interactions. To them, the online world will always be more superficial. But young people really see it differently.”
As the nature of online interactions continually evolve, it’s difficult to definitely establish whether or not social media friendships alone are sufficient. But for those who don’t have strong in-person support groups, the value of online communities shouldn’t be dismissed.
1.The underlined part in Paragraph 2 probably means that the screens are ______.
A.becoming more and more appealing
B.controlling what people talk about with each other
C.making face-to-face conversations less efficient
D.changing the way people communicate with each other
2.What is the advantage of online interactions according to Milkami?
A.More positive topics will be focused on.
B.Communication efficiency will be improved.
C.People will feel more comfortable with communicating.
D.People will have more in-depth communication with others.
3.Which of the following will the author agree with?
A.Compared with the real world, the online communities are superficial.
B.It is impossible to know whether social media friendships are sufficient.
C.Teenagers can depend on online interactions to strengthen their friendships.
D.The importance of online communities should be considered for some people.

Few people can resist the lure (诱惑) of a delicious ice cream, especially on a hot day. The only thing that spoils the fun is that the treat is hard to enjoy slowly, often ending up with a sticky melted mess. Now, researchers from Colombia's Pontificia Bolivariana University may have found an unlikely partner to help solve this age-old problem---cellulose fiber(纤维素) extracted from banana plant waste. Bananas, as you probably know, grow in bunches on a tree-like plant. Each bunch is attached to a central stalk, called a rachis(叶轴), which is thrown once the fruit has been harvested. The team, led by Dr. Robin Zuluaga Gallego, began extracting cellulose nanofibrils (CNFS) from powdered rachis. The tasteless, odorless macro fibers, thousands of times smaller than the width of a human hair were then added in various concentrations to 100 grams of ice cream mix.
With the right amount of CNFS mixed in, the dessert lasted longer in its frozen state than conventional ice cream, extending both its shelf life and the amount of time the treat can be enjoyed. Even more exciting was that the fibers increased the stickiness of low-fat ice cream to levels higher than the full-fat one. Since this is what determines the frozen treats’ creaminess and texture, CNFS could help create healthier ice cream without compromising on taste.
The researchers, who presented their findings at the American Chemical Society (ACS) meeting in New Orleans on March 21, 2018, next plan to investigate how different types of fat, such as coconut oil, affect the behavior of CNFS in other frozen treats.
The Colombian researchers are not the only one working on creating a slower-melting ice cream. In 2015, scientists at the University of Dundee in Scotland found that a naturally occurring protein called BSIA(Bacterial Surface Layer A) was remarkably effective in keeping the treat frozen for longer periods of time. With both teams competing to be the first to get to market, the future of everyone’s favorite dessert certainly looks promising.
1.What prevents people enjoying an ice cream slowly?
A.The hot weather.
B.A kind of fiber from banana.
C.The ice creams’ stickiness.
D.The ice creams’ quick melting.
2.Which is NOT a benefit of CNFS added to ice cream mix?
A.To improve its flavor.
B.To make it more healthy.
C.To reduce its fat content.
D.To make it melt more slowly.
3.What can be inferred from the last paragraph?
A.CNFS are more useful and effective than BSLA.
B.Ice cream with BSLA has been on sale at the market.
C.Slowly enjoying an ice cream will soon become a reality.
D.The Colombian research team has taken the lead in the competition with the Scottish team.
4.What's the author’s attitude towards the finding of CNFS?
A.Positive B.Casual
C.Defensive D.Suspicious.

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
I am one of those unfortunate people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the spot I was heading for.
I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going.
If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.
1.What is the writer going to do when someone asks him for direction?
A. He will direct the right way to the person willingly.
B. He will reply to it by the means of being a stranger to the town.
C. He will give the very person long list of direction.
D. He is going to show the man an opposite direction.
2.Why did the writer consider himself to be an unlucky dog?
A. Because of his poor sense of direction.
B. Because he always forget the way to home.
C. Because he did not have any friend.
D. Because he used to be shy and dared not ask others the way.
3.How did the visitor feel when he was showed into the very room?
A. He felt strange. B. He felt embarrassed.
C. He felt very sad. D. He felt astonished.
