Since technology has become popular, a new term was created for trouble on the web. cyberbullying. Cyberbullying is willful and repeated harm caused by the use of computers, cell phones or other electronic devices. Research on teens shows that 50% of them in our country have been bullied in their lifetime and 1/3 have been bullied online. 1.
Before that, it' s important to understand why cyberbullying happens. One reason is revenge(报复). 2. Another is that they sometimes just don' t understand what they are doing is wrong. In some cases, they think they are being funny.
3. But they couldn't be more wrong. The potential problem is that bullies will get into trouble in school, at home or even by the police if what they are doing is a threat. 4. Experiences with cyberbullying are linked to low self-respect, depression and even killing oneself.
If you have been affected by a cyberbully, there are some things you can do. If someone posts a mean comment, don't feel like you need to revenge. 5. You can also counteract(抵消) the negativity by creating positive content, such as posting nice and uplifting things on your Weibo or Wechat accounts. Finally, if the abuse really affects your social relationships, get help from a trusted adult or turn to the law. Together, cyberbullying will become a thing of the past.
A. Then what about their victims?
B. The victims are in need of help.
C. Bullies may think their comments are no big deal.
D. This problem is affecting so many teens across the country.
E. Delete it or keep all evidence by taking screenshots and report it to the app.
F. The other person did something to the bullies, and they feel it right to do it.
G. Therefore, we should look into the problem more carefully to see what can be done to end cyberbullying.
As the saying goes, "An apple a day keeps the doctor away." That's because this healthy food choice is supposed to be full of nutrients. The apple at the supermarket, though, might be so o1d that it has lost many of its nutrients. But soon there might be a way to check the quality of fruit by scanning it.
Scientists at Food+Future coLAB have come up with the idea of a handheld spectrometer(分光仪) that scans food. The machine will work by shining infrared(红外线的)light on a piece of produce. By measuring how chemicals in the fruit or vegetable take in the light, the scanner can recognize the food's chemical makeup.
"The machine can tell you exactly how old an apple is, how many calories it contains, what nutrients are present inside it, and even small differences in taste," Greg Shewmaker of Food+Future coLAB recently said.
For the new machine to be useful to consumers, researchers first need to create a database that contains possible chemicals for a particular type of fruit, like an apple, for example. Scientists will need to scan lots of pieces of produce to collect this data. The information collected will allow the scanners to tell customers the quality of fruit.
Once consumers know what's inside an apple, they can decide if they want to buy it. Knowing fruit quality may also affect how a store prices produce. "We can price produce based on the nutritional value," Shewmaker explained.
Food+Future coLAB has already created a working model of its machine. It says you may see one in your local supermarket within the next few years. Then deciding whether you've picked the healthiest fruit will be just a quick scan.
