1 . The teenage years of an individual is marked by evaluating one's values,experiencing a shift in outlooks,and a tendency to act rebellious. It can also be a time when someone becomes extremely____ to negative influences,and is drawn towards dangerous situations. On the other hand,for parents, the period of their children's adolescence means regularly worrying about their safety and formation as a citizen. Thus, a method of _____teenagers' security is needed, and curfews(宵禁)are often seen as such a measure，since they have proved their ______the same time, certain peculiarities exist about establishing curfews for children.

The issue of teenage curfews is widely debated in the United States, where this method is still rather _____, and in European democracies, where this measure is yet not so widely used .The first and foremost reason for establishing curfews is children's security. ____curfews require teenagers under 17 years to stay out of streets starting from 11p.m.or midnight. This is believed to protect them from crimes committed after nightfall,as well as from breaking the law, and there exists serious evidence _____this belief. For example, when New Orleans enabled a dusk-til-dawn curfew in 1994, the rates of juvenile crime were reported to fall more than 20 percent.Even more impressive _______were recorded in Dallas, which reported a 30-percent decrease in violent juvenile crime,and a 21-percent decrease in the overall rates of crimes committed by young people (The New York Times).

On the other hand, curfews can be seen as a preventive measure that rob young people of their rights,____ their freedom. This opinion is _____ supported by the fact that curfew violations(违规) and the respective charges are among the most often committed juvenile crimes in the United States. _______, there were reports claiming that police arrested more non-white teenagers for curfew violations.All this can cause a teenager to believe they have crossed a psychological line dividing them as criminals; thus,such teenagers may start to see themselves as outlaws, which can _____ committing more serious crimes than a curfew offense.

What is important for a parent to remember when establishing a curfew for their children is that a teenager's misjudged view of certain______may cause them to misbehave in some other way; this is proved by research conducted by the University of Minnesota, according to which teens tend to protest against what they see as _______. Considering this,parents should ______the authoritarian style of establishing curfews; instead, they should have a conversation with their teenager that would be aimed at finding ideal conditions for a curfew that would ______both sides.

5 . Communities across the world are starting to ban facial recognition technologies. The efforts are well intentioned, but banning facial recognition is the wrong way to fight against modern surveillance （监 视）.Generally, modern mass surveillance has three broad components: identification, correlation and discrimination.

Facial recognition is a technology that can be used to identify people without their consent. Once we are identified, the data about who we are and what we are doing can be correlated with other data. This might be movement data, which can be used to "follow” us as we move throughout our day. It can be purchasing data, Internet browsing data, or data about who we talk to via email or text. It might be data about our income, ethnicity, lifestyle, profession and interests. There is an entire industry of data brokers who make a living by selling our data without our consent.

It's not just that they know who we are; it's that they correlate what they know about us to create profiles about who we are and what our interests are. The whole purpose of this process is for companies to treat individuals differently. We are shown different ads on the Internet and receive different offers for credit cards. In the future, we might be treated differently when we walk into a store, just as we currently are when we visit websites.

It doesn't matter which technology is used to identify people. What's important is that we can be consistently identified over time. We might be completely anonymous （匿名的）in a system that uses unique cookies to track us as we browse the Internet, but the same process of correlation and discrimination still occurs.

Regulating this system means addressing all three steps of the process. A ban on facial recognition won't make any difference. The problem is that we are being identified without our knowledge or consent, and society needs rules about when that is permissible.

Similarly, we need rules about how our data can be combined with other data, and then bought and sold without our knowledge or consent. The data broker industry is almost entirely unregulated now. Reasonable laws would prevent the worst of their abuses.

Finally, we need better rules about when and how it is permissible for companies to discriminate. Discrimination based on protected characteristics like race and gender is already illegal, but those rules are ineffectual against the current technologies of surveillance and control. When people can be identified and their data correlated at a speed and scale previously unseen, we need new rules.

Today, facial recognition technologies are receiving the force of the tech backlash （抵制），but focusing on them misses the point. We need to have a serious conversation about all the technologies of identification, correlation and discrimination, and decide how much we want to be spied on and what sorts of influence we want them to have over our lives.

It is a common sight on campus or in the streets: a young person rides by on an electric scooter, traveling quickly and proudly. But Beijing’s traffic authorities have said that starting on Sept.5, people who are caught riding electric scooters on public roads or bicycle lanes will be fined 10 yuan. They will also be given a warning not to use the vehicles on public roads again.

The announcement was made after traffic police in Shanghai started a campaign to get electric scooters off public roads, with police officers stopping riders because the scooters could cause traffic problems.

The Beijing Consumer Association said it had tested more than 20 electric scooters of different brands recently and found that most had substandard brakes. It added that 16 of the tested scooters could go faster than the maximum 20 km per hour set for electric bikes. According to the traffic police, people who ride electric scooters at certain speeds can easily bump into the vehicles in the vehicle lane and hurt people who walk in the bicycle lanes.

But seeing the benefits that electric scooters have brought to young people, experts are worried that the ban may take effect slowly.

Electric scooters are a great answer to the ‘last mile problem’ of getting from a public transport station to one’s home. They’re light enough to throw over your shoulder. They’re easy to ride just about anywhere and don’t need a lot of physical effort. The scooter can travel 25 km on one charge. It’s convenient and easy to control.

They are also good for environment. Unlike cars and buses, electric scooters produce no carbon dioxide, need no fuel and make almost no noise.

For many young people, they use them to copy cool celebrities they have seen in videos.
