2 . Nowadays some companies are attempting to grow seafood from cells in a laboratory rather than harvesting it from the oceans.

With massive problems with overfishing worldwide and growing demand for shrinking supplies of seafood, the way fish currently makes its way to our plates isn't a long-term viable option. Between 1961 and 2016, the average annual increase in global food fish consumption outpaced population growth. Those are figures not sustainable for us, the fish or the environment as a whole.

Cellular seafood could be the answer. Just don't make the mistake of calling it lab-grown fish. ''None of us in the industry would call it lab-grown seafood, '' says Mike Selden, CEO of Finless Foods. ''Finless Foods isn’t lab-grown. We experiment and create our science in the lab, but don't produce there. Our products come from a production base much like a farm as a production base for animals.''

Finless Foods is a tech company in San Francisco. Beginning in 2017, it's been working to bring to market a species of cultured bluefin tuna (蓝鳍金枪鱼) created using cellular technology. Shortly after that, the company produced its first pound of bluefin tuna meat for a cost of about $19,000. Since then, however, it's been working to bring that price down.

Selden terms what Finless Foods is doing as ''cell-based seafood''. ''We're growing seafood from real seafood cells,'' Selden explained. ''We take cells from a fish once, and then grow them endlessly from that. We do the same process that happens inside of a fish and make it happen outside of a fish. ''

The goal of cellular seafood isn't to entirely destroy the current seafood industry. Instead, it's intended to augment it—and perhaps to help reduce some of the more harmful aspects of current fishing practices like overfishing and illegal fishing. And when it comes to certain sea species, this laboratory-based approach could help create a plentiful supply of certain fish without endangering the survival of certain overfished species as a whole.

4 . 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.
