What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make _____, of course, but we can be sure that he will be different from what he is today, for man is slowly _____ all the time.

Let us take an obvious _____. Man, even five hundred years ago, was shorter than he is today. Now, on average, man is about three inches taller. Five hundred years is a relatively short period of time, so we may _____ that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity (能力). As time goes on, _____, we shall have to use our brains more and more, and _____ we shall need larger ones! This is likely to _____ a physical change to the head, and in particular the forehead, which will grow larger.

Nowadays our eyes are in _____ use. In fact, we use them so much that very often they become _____ and we have to wear a pair of glasses. But over a very long period of time it is likely that man’s eyes will grow stronger.

On the other hand, we have a (n) ______ to make less use of our arms and legs. They, ______, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive ______ they are used a great deal in modern life.

Another we are ______ about is our hair. This will ______ from the body altogether in the course of time because it does not ______ a useful purpose any longer. In the future, then, both sexes are likely to be bald (秃顶的).

Perhaps all this gives the ______ that future man will not be a very ______ creature to look at! This may well he true. All the same, ______ all these changes, future man will still have a lot in ______ with us. He will still be a human being, with thoughts and ______ similar to our own.

   What makes us human？Is it our thoughts？Our emotions？Our behavior？

All of these things make us who we are，but at the center of it all lies the genome — the genes inside our bodies that determine everything from our hair color to our intelligence. But if we could change our genome，would we still be human？

Recently，a group of scientists from the US and South Korea worked together to successfully“edit”a human embryo（胚胎）and remove a genetic mutation（变异）that would have led to heart disease. This was achieved with the help of CRISPR-a gene — editing tool that allows scientists to edit the genome by cutting，changing or adding to parts of it.

Scientists involved in DNA editing are certain about the good of their work，and hope that in the future，diseases could simply be“edited out”.

However，others aren't so sure. People are worried that the science could be used not only to remove life-threatening illness，but also to make a“perfect”baby whose DNA has been chosen to improve its intelligence or other qualities. They say that this is a shallow way of thinking about raising children.

“It makes you think about who we are as people，and it makes you ask if humans should use the kind of power…that is changing human evolution（进化），”Jennifer Doudna of the University of California said.

Still，others worry that DNA editing could be turned into an expensive service that would only be available to the people who could afford it. That might mean the rich would be given another advantage in a world where they already have plenty of them.

“You could find wealthy parents buying the technology for their children, leading to even greater inequality than we already live with,”Marcy Darnovsky, director of the San Francisco Center for Genetics and Society, said.

   The paperless office was first invented in 1975. Four decades later, we’re still chasing (追逐) the paperless office dream. Take the financial industry for example — it is one of the slowest industries to hug digital transformation. Many financial institutions today still send out trade confirmations (确认函) by mail. I can tell you from first-hand experience that going paperless is by no means impossible. The Centric Digital office is a paperless work environment where all the office operations go digital, which has amazed our business partners.

Actually, companies need to stress the benefits of a digital culture. Going paperless can save time and money. You could say goodbye to costly repairs, office supply orders, wasted employee time and so on. Besides, forbidding paper in the office forces information to be 100% digital, where you can make countless backups (备份), which easily increases transparency (透明). Not to mention, top talents want to work for digital companies.

You might think the secret to a paperless company is purely technology. Well, not really. Thanks to products like iPads, smartphones, and cloud services, the ability to go paperless is highly accessible. Yet, even with all this technology, companies continue to rely on paper. It’s not because they don’t have access to the technology, but because they’re lacking the policies, organizational structure, and strong desire to change. In order to go paperless, companies need to change the way they think and operate. The decision needs to be made and carried out, and everyone needs to work together to make it.

Yes, the paperless office has been a very long time in the making — but it no longer has to be. With plenty of software, services, apps, and technology available today, the only thing we need to do is make the decision to go paperless and see it through.

   Let us suppose it is now about A. D. 2060. Of course things have changed and life is very _____ .

Voyages to the moon are being made every day. It is as _____ to take a holiday on the moon today as it was for the people in the 1960s to take a holiday in Europe. At a number of _____ on the moon, many hotels have been built. The hotels are air-conditioned _____ In order that everyone can _____ the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for the _____ of the young and the old.

What are people _____ now? People are still eating food. They haven’t yet started to take the electrical current or nuclear power as their _____ of energy directly. They may do this some day. But many kinds of foods now come _____ pill form, and the food that goes into the pill continues to mainly ______ green plants.

______ there are several times as many people in the world today as a hundred years ago, most of our planet’s surface has been filled. The deserts are ______ regularly with water and crops are no longer destroyed by pests (害虫). As a result, the ______ is always good.

Farming, of course, is very highly ______ Very few people have to work on the farm; it is possible to ______ the farm by just ______ a few buttons now and then.

People are now largely vegetarians (素食主义者). You see, as the number of people ______, the number of animals decreases. Therefore, people have to be vegetarians. And we are ______ both in our bodies and in our minds for we know the causes of diseases and pain and the ______ to them, and it is possible to ______ diseases.

Such would he our life in 2060.
