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.

Helping and supporting others may be key to living a longer and healthier life, according to a new research from the University of Bagel in Switzerland. The findings published in the journal Evolution and Human Behavior, show that grandparents who care for their grandchildren enjoy longer lifespans. So do old people who care for others within their social networks.
Using data from the Berlin Aging Study, the researchers analyzed the longevity(寿命) and caregiving habits of more than 500 old people between the ages of 70 and 103. The study compared grandparents who acted as occasional caregivers with those who did not. It also compared these grandparents with old adults who did not have grandchildren but cared for people within their social networks.
Those grandparents who did not play the role of attending to grandchildren were more likely to have died within just five years of the testing period. While those old adults who provided, support to their family lived for an extra seven years on average and those provided support to their social networks lived for an extra four years on average.
Although the new study only focused on old adults, it's safe to assume that the health benefits of helping and taking care of others also reach those of all ages. However, it's important to note that too much caregiving often has just the opposite effect. There's a clear link between too much caregiving and a number of negative physical and mental health consequences.
1.How many groups of old people are involved in the study?
A. Two. B. Three.
C. Four. D. Five.
2.What does the research show?
A. Old people are more likely to support others.
B. Grandparents live longer than childless old adults.
C. Supporting others prevents diseases of old patients.
D. Helping others properly has a good effect on health.
3.What does the last paragraph imply?
A. Reducing earegiving can avoid bad health.
B. It's a good quality of all ages to be helpful.
C. Caregiving is not always beneficial to health.
D. Mental disorder is often caused by much caregiving.
People who report news sometimes find themselves in the news. This is especially true for foreign correspondents(记者), who risk their lives to bring us important stories from dangerous parts of the world. To learn more about the life of a foreign correspondent, we interviewed Tim Craig, who has covered the conflicts in Afghanistan and Iraq.
Q1: What draw you personally to dangerous places?
Tim Craig (TC): Experiencing problems that still exist in the world, seeing the struggles that soldiers face to keep peace, and the calamity that people meet during the war, and gaining a better understanding of how people from different countries live.
Q2: What do you like about your job?
TC: I like being able to talk to lots of different people about their problems and concerns. Sometimes the job can make you sad.

Q3 : Do you worry about your own safety? How do you deal with that?
TC: Yes, I do worry, but I try not to think about it all the time.

I watch from the wooden bench in my backyard as the water from the pipe quietly flows out onto the tomato plants. I watch the plants and rest easy, knowing the pipe is taking care of the plants. The drops soon seem to become rivers on the ground.
I see these red-brown ants, crawling(爬行) along around their home. What will happen when the water reaches the ants? Smelling the danger, these poor tiny creatures all run away from the water and rush back to their home. They spend their whole lives working together to create and make better things, but now they are facing the end of it all. I think this is just a reflection of the world. I keep watching as the water first attacks and then surrounds two ants. They struggle to stay floating as the water closes in on them, getting deeper and deeper. I try to get these two to come on my finger, but they refuse to let me save them. The water soon flows over them, as I remain helpless. Only then do they decide to climb onto my dirt-covered finger. Not until facing the moment of death would they trust one like me.
I check to see if they are alive, and both can move fine. Then I go to save other ants. However, the water washes everything away. How much I wish I could turn off this machine of death, but I cannot. I must complete my job.
It knocks me how much these little lives mean to me. When I was a small child, I would make a sport of killing them. Now, I can't hurt an insect, always thinking about what it would be like to be so small.
