1 . China has completed its BeiDou Navigation Satellite System (卫星导航系统), or BDS, becoming another one in the world with a global (全球的) navigation network, the other three being GPS of the US, GLONASS of Russia and Galileo of the European Union.
As the name suggests, the global navigation satellite system provides navigation and location services 24 hours a day. From what we have known so far, building a good satellite system costs a lot. Why does China have a new one if there is nothing special?
The other three systems have 24 satellites in MEO. Besides the 24 satellites, China’s new global navigation satellite system BeiDon-3 also has three satellites in GEO and three in IGSO. What’s special about these six satellites is that they have a relatively fixed area of activity. This can improve BDS’ accuracy (精准度) in China and the Asia-Pacific region to 5 meters, compared with a 10-meter accuracy in other areas.
BDS has another advantage - the short message service. It allows users to have a two-way communication. In areas not covered by communication signals (信号), BDS can make the short message service available in uninhabited areas, such as deserts, forests, mountainous and polar areas. With this service, users who are in danger can tell the rescue team (救援队) their location and condition.
In fact, BDS is also good business. According to the official report, China’s satellite industry has kept a 20% annual growth since 2012. And BDS contributes (贡献) about 80% of it. BDS has also created countless high-paying jobs. And with continuous improvement, it will have much more to offer in the future.

| A．It can only be used in China. |
| B．It is good for China’s development. |
| C．It has made lots of people lose their jobs. |
| D．It doesn’t work in areas where there is no communication signal. |
2 . What subject do you worry about the most at school? Many students worry about math. Some students can’t sleep well the day before a math exam. Others may feel very nervous during the exam itself. But there might be a way to make the subject less stressful.
“For people who are anxious about math, posture (姿势) makes a big difference,” Erik Peper from San Francisco State University told the Daily Mail. That’s right—sitting up straight can help you do better on math exams.
Scientists tested 125 college students. They asked them to do a simple math quiz (测试) while siting in a slumped-over (趴倒的) position, or sitting up straight. After the test, 56 percent of students said the exam was easier to do if they were sitting up straight.
Slumping over is a defensive (防御的) posture. It can trigger (激发) negative memories in the body and brain. This can stop you from thinking clearly, Peper said.
Students who were not nervous about taking the math exam did not necessarily benefit from better posture. But they did find that doing math while slumped over was more difficult, Science Daily reported.
Good posture isn’t just helpful for taking math exams. Athletes, musicians and public speakers can all benefit from better posture. When you feel stressed out, you can also try to sit up straight or stand tall. It can help you feel more positive and focus better.

3 . Your handshake is a part of your first impression (印象). Do you want your handshake to say good things about you? Here are some ways to help you learn how to shake hands correctly.
Know who to start. The person in a higher position or who is older should be the first one to reach out a hand. For example, if you are interviewed for a job, the interviewer should be the one to take the lead.
Don’t offer an unannounced handshake. If you offer someone your hand when they aren’t paying attention, they may not shake hands with you. It doesn’t mean the person doesn’t want to shake your hand. So start with a greeting to let others know that you’re here.
The handshake often lasts about 2 to 5 seconds. Most people don’t spend more time shaking hands. If the other person holds your hand for more than five seconds, politely withdraw (撤回) your hand.
Don’t show a sweaty (出汗的) hand. If you hand someone a sweaty hand, you may make them uncomfortable. Before shaking their hand, dry your own hand. If you’re holding a drink, hold it in your left hand so that it won’t make your right hand wet or sweaty because we often use our right hand to shake hands with others.
Shake hands in an up-and-down direction. Don’t go back and forward or side to side. Don’t swing the other person’s hand more than three times. It may make the other person uncomfortable.

In classes, your teachers will talk about the topics that you are studying. They provide important information for you to know when you take tests. So you must be able to take good written notes from what your teachers say. Here are the three stages（阶段） of taking notes and what you should do during each stage.
1.Before Class
Review your notes you have taken before you come to class. This will be good for remembering what was covered, and get you ready to understand new information in class.
2.During Class
Keep your attention on what your teacher is saying and “the signal words” that tell you what your teacher is going to say and it is important to write them in your notes. Examples of signal words are “the most important point… and remember that…”. Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations（缩写） such as med for medicine, using symbols such as “%” for percent, and writing short sentences.
3.After Class
Rewrite your notes to make them more complete and accurate（准确） by changing abbreviation into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.

7 . In Chinese culture, the color red stands for many good things, for example, happiness. But writing names and letters with red pens is usually avoided. Why?
In ancient times, red was the symbol of power. Not everyone could write with red pens—only emperors. They would reply to officials’ memorials（奏折）with red pens. The red ink that emperors used was made of cinnabar（朱砂）.
Writing with red pens was also related to death. In ancient China, the criminals who were sentenced to death（被判死刑）signed their names with red pens. The records of criminals’ names were all written in red words. Names on the tombstones（墓碑）were red as well. Therefore, it was thought to be unlucky to write names with red pens. Since red words carry bad meanings, people don’t write letters with red pens.
Nowadays, red pens are used for proof-reading（校对）. Teachers mark students’ homework with red pens. Editors who need them to correct mistakes in newspapers and magazines. But writing names or letters with red pens is still a bad idea to many people.
