1 . The teenage years are probably the most unsettled and stressful years in a person’s life. Teens experience significant physical, emotional, social and cognitive changes. And teens of today face more challenges as they go through more uncertain times of the 21st century.     1    

As teens experience massive physical, social and emotional changes, the challenges are managing social expectations of ideal body images, developing their identity and finding their place in the world. In the past, a teen who was criticized for his or her larger figure or pimpled (有粉刺的) face, might feel embarrassed and dejected in school.     2     Constant comparison and endless posts of picture — perfect images and lives give teens greater pressure to follow current fashion trends. The Wall Street Journal reported that Instagram made body images worse for one in three teenage girls.

    3     Statistics show that most cases of cyber bullying take place on popular social media sites such as Facebook, Instagram, Snapchats and Twitter, where cyber bullies make emotionally scarring comments. These can be made publicly on a teen’s social media account.     4     As a result, cyber bullying can be more threatening than traditional bullying because it can be shared and viewed repeatedly on social media. In this age of social media, it is also important for teens to learn to cultivate positive, and healthy relationships with people.

There have been many discussions about new technologies and ways of working, such as artificial intelligence (AI) and automation, which will impact future jobs.     5    . Unlike in the past, the situation is different today as AI and automation are causing some jobs to disappear. Teens will have to meet this challenge by adopting an attitude of lifelong learning, and keeping paces with technology.

A．They can also be spread quickly by sharing with others.

B．Furthermore, social media has taken bullying to a new level.

C．The future has always been a dreamland for teens to anticipate.

D．Today, these same sufferings can be expanded by social media.

E．Social media, and technological advances are posing new challenges.

F．Additionally, social media is a strong tool for a teen to defend himself.

G．The challenge for a teen today is preparing for a largely unknown future.

2 . Over millions of years humans have responded to certain situations without thinking too hard. If our ancestors spotted movement in the nearby forest, they would run first and question later. At the same time, the ability to analyze and to plan is part of what separates us from other animals. The question of when to trust your instinct (直觉)and when to think slow matters in the office as much as in the savannah(草原).

Slow thinking is the feature of a well-managed workplace. Yet instinct also has its place. Some decisions are more connected to emotional responses and less to analysis. In demanding customer-service or public-facing situations, instinct is often a better guide to how to behave.

Instinct can also be improved. Plenty of research has shown that instinct becomes more unerring with experience. In one well-known experiment, volunteers were asked to assess whether a selection of designer handbags were real or not. Some were instructed to operate on instinct and others to deliberate(深思熟虑)over their decision. Instinct worked better for those who owned at least three designer handbags; indeed, it outperformed analysis. The more expert you become, the better your instinct tends to be.

However, the real reason to embrace fast thinking is that it is, well, fast. It is often the only way to get through the day. To take one example, when your inbox floods with new emails at the start of a new day, there is absolutely no way to read them all carefully. Instinct is what helps you decide which ones to answer and which to delete or leave unopened. Fast thinking can also help the entire organization. The value of many managerial decisions lies in the simple fact that they have been made at all. Yet as data explodes, the temptation(诱惑)to ask for one more bit of analysis has become much harder to resist. Managers often suffer from overthinking, turning a simple problem into a complex one.

When to use instinct in the workplace rests on its own form of pattern recognition. Does the decision maker have real expertise in this area? Is this a field in which emotion matters more than reasoning? Above all, is it worth delaying the decision? Slow thinking is needed to get the big calls right. But fast thinking is the way to stop deliberation turning to a waste of time.
