    Learning matters in living a full and rich life. You can take your passing interest in art and explore it more deeply. You can also improve your career prospects by learning new skills. 1.

1. They expand their library of books regularly.

As businessman Jim Rohn remarked, “Some people read so little they have rickets of the mind.” People with non-stop learning are often found browsing for books on Amazon. 2. Lifelong learners also ask friends and family for book suggestions, especially for non-fiction titles.

2. 3.

Deep engagement with learning makes the experience more valuable and easier to remember. Fortunately, this tip is easy to use. Simply take a few minutes during a class break to write down some questions about the material. If you are taking a business course, you can always ask questions about how to apply the material to your career goals.

If you are uncomfortable asking questions in front of other people, there are other options. 4.

3. They learn to earn.

5. Lifelong learners view their education as an investment with several components. For example, project management professionals are required to pursue ongoing education in three areas: leadership, technical knowledge and management.

If you are seeking to increase your income, consider learning sales and marketing skills. Those skills make a great difference even if you are not in a traditional sales job.

A.They learn from experiences that help them grow.

B.To discover the benefits of lifelong learning, read on.

C.They take the time to ask questions when they take courses.

D.Continuing education is vital to maintain your career growth.

E.Moreover, they like visiting their local library or book stores.

F.However, reading can not only broaden our vision but also cultivate our taste.

G.You can send questions by email or ask for an appointment to discuss the matter in depth.

The values of artistic works, according to cultural relativism(相对主义), are simply reflections of local social and economic conditions. Such a view, however, fails to explain the ability of some works of art to excite the human mind across cultures and through centuries.

History has witnessed the endless productions of Shakespearean plays in every major language of the world. It is never rare to find that Mozart packs Japanese concert halls, as Japanese painter Hiroshige does Paris galleries, Unique works of this kind are different from today’s popular art, even if they began as works of popular art. They have set themselves apart in their timeless appeal and will probably be enjoyed for centuries into the future.

In a 1757 essay, the philosopher David Hume argued that because“the general principles of taste are uniform(不变的) in human nature,”the value of some works of art might be essentially permanent. He observed that Homer was still admired after two thousand years. Works of this type, he believed, spoke to deep and unvarying features of human nature and could continue to exist over centuries.

Now researchers are applying scientific methods to the study of the universality of art. For example, evolutionary psychology is being used by literary scholars to explain the long-lasting themes and plot devices in fiction. The structures of musical pieces are now open to experimental analysis as never before. Research findings seem to indicate that the creation by a great artist is as permanent an achievement as the discovery by a great scientist.

    Scientists have discovered that rats have adapted to modern human life, even adapting their diets to the cities they live in.

The scientists claim that it could be possible that humans and rats have had similar changes in their genetic make-up, due to modern city life. The downside of the changes in the DNA is that they could make rats susceptible to the same health problems as humans, such as pollutants and sugary foods.

The study showed that rats’ diets have also adapted to their environment. In New York, you can see them eat bagels and beer; in Paris, they like croissants and butter. They adapt in amazing ways. The scientists also analyzed the genomes (基因组)of 29 New York rats and compared them with those of nine brown rats from Heilongjiang Province, north-east China. The finding showed that dozens of rat genes had been through major DNA changes over the centuries, as the rats spread from Asia to Europe and America, and from the countryside and into cities.

The changed genes were associated with diet, behavior, and movement, which added pressures and challenges for the rat to overcome. This could reflect the fact that urban rats have to move through highly artificial environments that are very different from natural habitats. So these gene changes might have evolved to help them move more easily through underground channels and pipes.

As the rats are closely associated with city-living humans, the scientists believe that it is possible that similar changes have happened in both species.

In October 2019, scientists used rats to successfully test an enzyme(酶) that could be used to help people quit smoking. Two groups of rats were trained to self-administer nicotine, and over two weeks their nicotine intakes increased, suggesting addiction. Then, one group of rats was given the enzyme, which led to a decreased nicotine intake. The scientists say that the enzyme could be developed for human use in the future.

1.Which of the following best explains the underlined phrase “susceptible to” in paragraph 2?

C.Rats are distributed in every continent of the earth.

D.Rats have been adjusting themselves to the environment.

3.What is the purpose of testing an enzyme on rats?

A.To explore rats’ survival ability. B.To help people stop smoking.

C.To learn more about city rats. D.To tell apart nicotine and enzyme.

4.What is the best title of this text?
