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.{#blank#}1{#/blank#}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 (名人).

    According to experts, young people desire these jobs largely because of the wealth and the fame.{#blank#}2{#/blank#} 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{#blank#}3{#/blank#}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{#blank#}4{#/blank#}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{#blank#}5{#/blank#} 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. The younger generation don't favor these professions any more.

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

C. Unfortunately, they do not always have a positive effect on people's life.

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

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

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

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

    After opening the world's first commercial Direct Air Capture plant（直接空气捕集工厂）designed to pull CO₂ out of the air, Swiss company Climeworks is now trying to create the world's first “negative emission（负排放）” power plant.

    An international team of scientists has been working on a way to turn captured CO₂ into minerals. The project is called CarFix. Experts capture the gas, put it into water and send it to more than 700 meters underground. There the CO₂ on contact with a special kind of rock forms into a mineral.

    “Our results show that between 95 and 98 percent of the CO₂, sent underground was mineralized over the period of less than two years, which is amazingly fast,” says lead author of the CarFix project, Dr. Juerg Matter. Before this discovery it was thought that this mineralization could take hundreds to thousands of years.

    The DAC technology can collect CO₂ from the atmosphere and then store it underground or sell it to business needing the gas. For example, customers can use it in drinks. And the first plant in Zurich is supplying the captured CO₂ to a nearby greenhouse to “feed” vegetables. By using the company's CO₂ the customers can reduce their carbon mission as well as lower their dependence on energy.

    A 2015 study suggested that before the CarFix project, experts could collect CO₂, but they didn't have a large-scale（大规模的）method to safely treat it.

    Combining Climeworks' DAC technology with the CarFix mineralization process they will be able to create a system. This system doesn't put additional carbon back into the atmosphere. Actually it is carbon negative.

    “The economic cost of applying this kind of carbon capture technology on a large-scale is not particularly practical now, but for the first time we are seeing a realistic and effective system,” says Christoph Gebald CEO of Climeworks.

    Kids love to go online. There is so much to explore and learn. {#blank#}1{#/blank#}The answer to the question is as difficult as determining at what age a child can be left at home by themselves, since all children are different. Here are some questions to ask yourself to determine what is right for your child.

    {#blank#}2{#/blank#}

    Of course when you are trying to determine if you can let him or her go online, your child has probably already said, "I'm ready; I can handle it." But are they? {#blank#}3{#/blank#} How would they handle the material if they ran across it by accident?

    {#blank#}4{#/blank#}

    Does your child question other people's actions? Do they easily believe anything that is presented to them? It is an important question to ask to determine if your child is ready to go online alone.

    Have you taught them what the dangers are?

    {#blank#}5{#/blank#} Have you explained to them that there are people out there that might want to do them harm? It is a dangerous world out there. If you are going to let them wander around in the online world, they need to be prepared for what they might see or run into.

A. You may be thinking this is a strange question to ask yourself.

B. Is your child easy to cheat?

C. There are a lot of dangers online.

D. Are they ready to go online by themselves?

E. Is your child skilled in using a computer?

F. Unfortunately there is a lot of unpleasant material online.

G. At what age should you allow your child to go online alone?

    Many people prefer eating out instead of cooking at home. A change appears to be taking place, though, and millennials are leading the way. According to one survey, more young people are starting to cook at home for three basic reasons: They can save money, eat healthy and waste less food.

    Popular TV chefs are also getting millennials excited about learning some basic cooking skills. Many millennials view cooking as a form of entertainment and self-expression. They proudly post pictures of their cooking creations on Facebook or Instagram, and invite friends over to share the cooking experience.

    Many millennials have also found ways to avoid wasting food. After roasting a chicken, they put the leftover bones in their freezer instead of the garbage can. Later, they use the bones to make chicken stock which is an important ingredient in many dishes.

    They also hate throwing out fruit that's too old. To avoid that situation, they bake ripe fruit like berries and bananas for 15 minutes at 175 degrees C. Then they freeze it overnight. After that, they place the fruit in plastic bags and store it their freezer for later use.

    Now any millennials only eat at restaurants that have excellent food-waste policies. These servants use every part of the vegetables they buy, including their stems and roots, in dishes. They also use beef, chicken and pork bones to make their own stock.

    Millennials also reduce food waste by only buying what they require. Before going to a market, they write down what they need and don't buy anything else. They say they won't purchase more food than they can consume.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play has an important part in keeping you healthy.

    Use "the best medicine" to treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

    Anyway, adding humor, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humor, laughter and play to make our life more active, interesting and happier.
