After entering high school, you must wonder how to study well. Here are some good skills for you.

Go to class.

    If you want to do well at school, going to class is the first step in studying well. If you miss classes, you will miss what the teacher thinks is important; as a result, you'll miss what is the most likely to end up on the test.{#blank#}1{#/blank#}

Take good notes.

    Try not to write down everything.{#blank#}2{#/blank#}Write down unfamiliar terms. After class, review your notes as soon as possible. You can fill in details that you missed and review the material while it is still fresh on your mind.

    If you are struggling in class, talk to your teacher. He or she may be able to give you more help or tutor you before or after class. Most teachers have little sympathy(同情) for students who just become worried about failing during the last few weeks of the grading period.

    The online economy—from search to email to social media—is built in large part on the fact that consumers are willing to give away their data in exchange for products that are free and easy to use. The assumption behind this trade-off is that without giving up all that data, those products either couldn't be so good or would have to come at a cost.

    But a new working paper, released this week by Lesley Chiou of Occidental College and Catherine Tucker of MIT, suggests that the trade-off may not always be necessary. By studying the effects of privacy regulations in the EU, they attempted to measure whether the anonymization(匿名化) of search data hurts the quality of search results.

    Most search engines capture user data, including IP addresses and other data that can identify a user across multiple visits. This data allows them search companies to improve their algorithms(算法) and to personalize results for the user. At least, that's the idea. To determine whether storage of users' personal data improves search results, Chiou and Tucker looked at how search results from Bring and Yahoo differed before and after changes in the European Commission's rules on data retention(数据保存). In 2008 the Commission recommended that search engines reduce the period over which search engines kept user records. In response, Yahoo decided to strengthen its privacy policy by anonymizing user data after 90 days. In 2010 Microsoft changed its policy, and began deleting IP addresses associated with searches on Bring after six months and all data points intended to identify a user across visits after 18 months. In 2011 Yahoo changed its policy again, this time deciding to store personal data longer—for 18 months rather than 90 days—allowing the researchers yet another chance to measure how changes in data storage affected search results.

    The researchers then looked at data from UK residents' web history before and after the changes. To measure search quality, they looked at the number of repeated searches, a signal of dissatisfaction with search results. In all three cases, they found no statistically significant effect on search result quality following changes in data retention policy. In other words, the decision to anonymize the data didn't appear to impair the search experience. “Our results suggest that the costs of privacy may be lower than currently perceived,” the authors write, though they note that previous studies have come to different conclusions.

    In a natural disaster: a hurricane, flood, volcanic eruption, or other catastrophes. Minutes and even seconds of warning can make the difference between life and death. Because of this, scientists are working to use the latest technological advances to predict when and where disasters will happen. They are also studying how best to analyze and communicate this information once it is obtained.

    On September 29,1998, Hurricane Georges made landfall in Biloxi, Mississippi, after damaging Haiti, the Dominican Republic, Puerto Rico, and several islands of the Caribbean badly with heavy rains and winds up to 160 km per hour. Few people lost their lives along the Gulf Coast of the United States, although hundreds died in the Caribbean. This was a very different result, when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston, Texas, killing at least 6,000 people. Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century—residents of Galveston had no advance warning that a storm was approaching, while residents of Biloxi had been warned days in advance, allowing for extensive safety precautions (预防).

    At the same time that people in Biloxi were thankful for the advance warning, some residents of New Orleans, Louisiana were less satisfied. A day before Georges made landfall, forecasters were predicting that the hurricane had a good chance of striking New Orleans. Emergency management officials must begin evacuations (疏散) well before a storm strikes. But evacuation costs money. The mayor of New Orleans estimated that his city's preparations for Georges cost more than 50 million. After Georges missed New Orleans, some residents questioned the value of the hurricane forecasts in the face of such high costs.

    The different views on the early warnings for Hurricane Georges show some of the complexities (复杂) related to predicting disasters. Disaster prediction is a process of providing scientific information to the government officials and other decision makers who must respond to those predictions.

    "Have a nice day！" may be a pleasant gesture or a meaningless expression. When my friend Maxie says "Have a nice day" with a smile, I know she sincerely cares about what happens to me. I feel loved and safe since another person cares about me and wishes me well.

    "Have a nice day. Next！" This version of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone (腔调) with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else's is the management's attempt to increase business.

    The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don't know what to say. "Oh, you just had a tooth out? I'm terribly sorry, but have a nice day. "

    The expression can be pleasant. If a stranger says "Have a nice day" to you, you may find it heart­warming because someone you don't know has tried to be nice to you.

    Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it's nice to know they care enough to pretend they care when they really don't care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.
