According to a recent survey, violence (暴力) did happen in schools. Students showed their fear and parents and teachers were also     1     (annoy) at it. Experts hope     2     whole society should pay more attention to the mental health of     3     (teenager).

The topic of school violence is     4     (particular) hot now, and it calls for our great concern. We should try our best     5     (stop) violence happening at school because more and more students     6     personal safety could not be guaranteed (保证) would drop out of school. In fact, violence can     7     (learn). Children learn violent     8     (behave) from adults or from what they see on television or on the Internet.

If I meet with school violence, I will not answer violence with violence, for it will lead     9     more fighting. I will tell my teachers and parents about it. I think they will help medeal with it well and protect me from the bad guys.

All in all, we students should be responsible for     10     (we) and keep away from violence.

2 . You might think people all over the United States have Wi­Fi — wireless Internet service — and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the US capital, Washington D. C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

There is a ban (禁令) on Wi­Fi in Green Bank, along with anything else that can create electromagnetic (电磁的) waves. Officials say the waves could disturb the signals (信号) the telescope receives.

For many Americans, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

The observatory (天文台) is one of the largest employers in the area. The National Science Foundation (NSF) spends about $8.2 million a year to operate the observatory, telescope and educational center.

Jonah Bauserman is a technician. If he supposes there is a signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

People in the town respect the work of the scientists. And they say they are happy to live without Wi­Fi and mobile phones. “You know, instead of sitting here with our phones and other devices we’re out fishing, hunting and going to each other’s houses.” Everyone knows each other and communication is almost always face to face.

6 . In the coming era of budget cuts to education, remote learning could become a common thing.

The appeal to those in charge of education budgets to trade teachers for technology is so strong that they tend to ignore the disadvantages of remote learning. School facilities are expensive to build and maintain, and teachers are expensive to employ. It’s true that online classes do not require buildings and each class can host hundreds of people, which can result in greater savings, but moving away from a traditional classroom in which a living, breathing human being teaches and interacts with students daily would be a disaster.

Physically attending school has hidden benefits: interacting with peers and communicating with teachers are important skills to cultivate（培养）in young people. Moreover, schools are more than simple places of traditional learning. They are also places that provide meals, places where students receive mental help and other support.

Those policy-makers are often fascinated by the latest technology in education and its potential to transform education overnight. But online education does not allow a teacher to keep a struggling student after class and offer help. Educational videos may deliver academic content, but they are unable to make eye contact or assess a student’s level of engagement. Distance education will never match the personal teaching in a traditional classroom. In their first 18 years of life. American children spend only 9% of their time in school. Yet teachers are expected to prepare them to be responsible citizens, cultivate their social skills, encourage successful time management, and improve their capacity to compete in a competitive job market. Given these expectations, schools should not become permanently “remote”.

The power of the classroom is rooted in the qualities of the people gathered in the same place, at the same time, including their nature, empathy, devotion and so on. Technology, no matter how advanced, should simply be a tool of a good teacher.

7 . People are less willing to rely on their knowledge and say they know something when they have access (使用权) to the Internet. That suggests that our connection to the Internet is affecting how we think. Professor Evan F. Risko led a study where 100 participants (参与者) faced general knowledge questions, such as naming the capital of France. For half of the study, participants had access to the Internet. They had to look up the answer when they said that they did not know the answer. In the other half of the study, participants who did not have access to the Internet did differently.

The team found that the people who had access to the Internet were about 5 percent more likely to say that they did not know the answer to the question. And the people with access to the Internet reported feeling as though they knew less. “When a large amount of information is within reach, people seem less likely to rely on their own knowledge,” said Professor Risko.

Through the results, the researchers held that access to the Internet might make it less acceptable to say you know something but are incorrect. It is also possible that participants were more likely to say they didn’t know an answer when they had access to the Internet, because online searching offers a chance to confirm (证实) their answer or satisfy their curiosity.

“Our results suggest that access to the Internet affects the decisions we make about what we know and don’t know. We hope this research is helpful in our growing understanding of how easily access to large amounts of information can influence our thinking.” Risko said and planned to further the research in this area.

10 . As a young girl growing up in France, Sarah Toumi dreamed of becoming a leader who could make the world a better place. Her passion to help others was awakened when, from the age of nine, she accompanied her Tunisian father to his birthplace in the east of the country during holidays. There she organized homework clubs and activities for children.

Toumi witnessed first-hand the destructive effect of desertification (沙漠化). “Within 10 years rich farmers became worse off, and in 10 years from now they will be poor. I wanted to stop the Sahara Desert in its tracks.” A decrease in average rainfall and an increase in the severity of droughts have led to an estimated 75 percent of Tunisia’s agricultural lands being threatened by desertification.

Toumi recognized that farming practices needed to change. She is confident that small land areas can bring large returns if farmers are able to adapt by planting sustainable crops, using new technologies for water treatment and focusing on natural products and fertilizers rather than chemicals.

In 2012, Toumi consolidated (巩固) her dream of fighting the desert. She moved to Tunisia, and set up a programme named Acacias for All to put her sustainable farming philosophy (理念) into action. “I want to show young people in rural areas that they can create opportunities where they are. Nobody is better able to understand the impact of desertification and climate change than somebody who is living with no access to water.”

By September 2016, more than 130, 000 acacia trees had been planted on 20 pilot farms, with farmers recording a 60 percent survival rate. Toumi estimates that some 3 million acacia trees are needed to protect Tunisia’s farmland. She expects to plant 1 million trees by 2018. In the next couple of years, Toumi hopes to extend the programme to Algeria and Morocco.
