Facebook managed to put its vast treasure trove(±¦²Ø) of user data to good use before Friday¡¯s tragic terror attacks in Paris. The social network customized its safety check feature let users know whether their friends and loved ones in Paris are safe.

Users in the area are being alerted(֪ͨ) by Facebook¡¯s mobile apps, asked them whether they are safe, and offering to check on any of their friends. The app has also been sending out alerts to anyone who has friends in Paris, and Facebook¡¯s website lets anyone check on the status and whereabouts(È¥Ïò) of their friends as well as.

Most people have seen Facebook¡¯s safety check for the first time today, and the company actually lanched it in respond to the Nepal earthquake earlier this year. At the time, Facebook CEO Mark Zuckerberg wrote: ¡°When disasters happen, people need to know their loved ones are safe. It¡¯s moments like this when being able to connect really matters.¡±

Facebook wasn¡¯t the only tech company to direct reach out to its users in Paris after the terror attacks. AirBnB£¨¿ÕÖÐʳËÞ£© sent its customers in Paris a email advising them staying in place and follow the directions from local authorities, and Uber£¨ÓŲ½£© used its app to advise users ¡°not to move if absolutely necessary.¡±

¡¾ÌâÄ¿¡¿How to Study Smarter, Not Harder

Here are some of our favorite study tips that will help any student study smarter, not harder:

Recite As You Study

Reciting¡ªsaying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.

Take Fuller Notes

Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.

Study the Middle

The best time to review is soon after you¡¯ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.

Sleep On It

Study before going to bed, unless you are very tired. It¡¯s easier to remember material you¡¯ve just learned before sleeping than after an equal period of daytime activity, because your brain continues to think even after you¡¯ve fallen asleep.

Combine Memory and Understanding

There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding.

The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.

¡¾1¡¿You can notice your mistakes by ________.

A. saying things out aloud

B. taking notes

C. studying the middle

D. sleeping on it

¡¾2¡¿When taking notes, you should ________ to better help you with reading.

A. underline important notes

B. write notes in your own words

C. take down every detail

D. write as quickly as possible

¡¾3¡¿The writer advises you to ________ as it is easier for you to remember material.

A. study after a period of activity

B. do some exercise after studying

C. study as soon as you get up

D. study before going to sleep

¡¾4¡¿Which of the following is NOT helpful for your understanding?

A. Thinking about an idea in different ways.

B. Relating ideas and concepts with what you already know.

C. Reading from the beginning to the end without stop.

D. Going back to what first made you confused and start again.

Sleep is something we all do. But some people need to sleep more than others. Babies sleep most of the time. Children in school sleep about ten to twelve hours a night. Most adults sleep only seven or eight hours. ___¡¾1¡¿___

All parts of our bodies have to rest after they work.. Our arms need a rest after we lift heavy thing, When we run fast, our legs work hard. They get tired. We have to rest them. Our brains work hard, too. ___¡¾2¡¿__. We can sit quite still and rest our arms and legs. But our brains aren¡¯t resting. They go right on thinking as long as we are awake.

Our brains slow down a bit when we sleep and dream. ___¡¾3¡¿__ Instead of thinking wide-awake thoughts, our brains make up dreams. Some dreams are very pleasing. Some are not. Most of the time we forget them when we wake up.

Scientists have tried to find out what would happen if people were not allowed to sleep. They asked some people not to go to bed. The people stayed up all night and all the next day. They stayed up the next night too, and the day after. They played games, but they made mistakes. They forgot things. ___¡¾4¡¿__

The people grew rude and mean. They became angry with their friends. Finally they were too tired to stand up. When they sat down, they fell asleep.

Scientists have found that if people are not allowed to sleep and to dream, they act in an unusual way. __¡¾5¡¿__ But we do know that we need it to stay well. So tonight have a good sleep. Lie down under the covers. Shut your eyes. Let your thoughts wander. Soon you¡¯ll stop thinking. You¡¯ll be asleep.
