1 . As we know, mental health is in a worse situation among young people globally.     1     This not only lowers quality of life, but has a negative impact on a teenager’s growth. To get at the root causes of this decline, a group of scientists conducted a study and found the combination of high screen time and low “green time” greatly affects mental well-being. Children nowadays spend more time than ever in front of electronic devices.

The average daily screen time for 8-to-18-year-olds was 7.5 hours in the U. S. ten years ago. As the study states, “This greatly goes above guidelines of 2 hours per day.” Now the condition is worse by the fact that so many schools are using technology to teach classes. Indeed some screen time can promote connections and enable tasks to be done more efficiently.     2     In addition to troubling nerve stimulation, too much screen time takes the place of important protective behaviors for mental health such as physical activity, getting adequate sleep and academic activities.

The study authors suggest that green time could act as a cure for screen time, essentially balancing its negative effects.     3     The attention systems can be restored in natural environment when they are worn out, because they employ involuntary attention there, which is not tiring or effortful.

    4     The great nature could potentially function as a psychological well-being promotion intervention (干预) for children and teenagers in a high-tech era. This knowledge could be a guide to public health departments that are struggling to restore happiness and cheer in countless anxious teenagers.     5

B．Screen-based technology makes kids less attentive.

C．The frequency of depression and anxiety is increasing.

D．There are many more ways, nevertheless , in which it is harmful.

E．It suggests more outdoor projects like building parks could be fundamental.

2 . Rich and Famous

Twenty years ago the most common ambition of American children was to be a teacher, followed by working in banking and finance, and then medicine. But today’s situation is quite different.     1     Instead they most commonly say they want to be a sports star, a pop star, or an actor—in other words, they hope to become a celebrity .

According to experts, young people desire these jobs largely because of the wealth and the fame.     2     Let’s take athletes and singers as an example. Their careers are short-lived. Many athletes’ best time only lasts a few years and singers can have a very limited career. The field that was once the focus of their lives becomes something they have little or no involvement in. As a result, they’ll have a feeling of worthlessness and a lack of control.     3    The truth is quite simple: they have been so far removed from it for so long.

In spite of these disadvantages, there is greater ambition than ever among young people to achieve that status. They are not satisfied just making a living—they want to be rich and famous. Globally, more and more TV shows provide talent competitions where winners can achieve their goals in just a few weeks or months.    4    They unrealistically believe that this lifestyle is easily obtained and leads to great satisfaction.

While many people argue that there is nothing wrong with having such ambitions, others feel that this trend will finally lead to dissatisfaction as more and more people are unable to reach their goals.     5     That means they ignore the simple fact that great effort is needed before success. As a result, many people won’t realize their childhood dreams, which could have a negative effect on their happiness.

A．In many ways this has been brought about by the celebrity culture.

B．People no longer have a sense of satisfaction once their goals have been achieved.

C．Besides, it can be difficult for them to adapt back to a normal everyday life.

D．The younger generation don’t favor these professions any more.

E．Unfortunately, they do not always have a positive effect on people’s life.

F．The reason is that they don’t realize it takes talent and hard work to be rich and famous.

G．This quick way of gaining wealth and fame creates a celebrity culture among people.

I am the shared bike. I’d like to be on the street to serve for people. They can ride me just via a mobile app. But horrible things happen a few days ago. Several people stole some of us with paying their bills on the app but treated us badly. They broke my saddle and even threw my friends everywhere. We felt angry for which those bad guys had done. Thanks to some kindly people, we received careful “treatment”. Now, you help as well as the whole society’s attention is what we need most. We are designed to help people who are stuck the heavy traffic. We are neither toy nor private vehicles. Please obey the basic rules.
