Traditionally, we Chinese attach great importance to(依恋) our hometown and are often     1    (willing)to migrate to other places. However, in present times, in particular after the reform and opening-up policy was introduced, more and more people feel like     2    (settle)down in more developed cities just as my family members did.

My parents were both in Sichuan. In 1963, a time when     3    (graduate)were assigned(被任命的) jobs by the government, my father received a job in Beijing. After I was born in 1969, my parents went to work in Xinjiang.

In the 1980s, Chinese society was filled with hope, and people worked hard to achieve their dreams. So did my family. In 1988, admitted     4    Renmin University of China, I went to Beijing. It took me 72 hours by train    5    (travel)from Xinjiang to Beijing, with a distance of over 3,770 kilometers. In 1990, my brother also passed the entrance     6    (exam)and chose his favorite major and he was enrolled in a university in Guangzhou,     7    he now lives and works.

Recalling the changes over the past four decades, I think    8    (improve) transportation is very important to our family. The long distance kept us apart most of the time. Today,     9    speed and methods of transportation have been improved a lot, which has    10    (entire)transformed our life and can bring us together easily.

2 . With the rapid development of science and technology, we don’t know how different our life will be in the future.     1    .

At first we think about human relationships. In the year 2050, we will use computers almost every day. We will be making new friends through the Internet — even our husbands or wives will be met in this way.     2    . On the other hand, our relationship with people won’t be as important as they are today — we will feel a little lonely.

Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the housework for us.

    3     . Traveling to other planets or to the moon will also be available for everyone. Means of transport will, of course, change, too. We will be using solar-powered cars, which will be much more environmentally friendly.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true.     4    . And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in a better condition.

Although we can’t predict the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather confident about our future.     5    .

5 . Space tourism is the term used to describe space travel for recreational or leisure purposes. What was once only a dream, as described in A Space Odyssey by Arthur C. Clarke, is now becoming a reality.

Futurologists attempt to make predictions of what life will be like in the future. After the first man landed on the moon, they thought that hotels would be built on the moon by the year 2000. They also considered the possibility that, in the 21st century, families might go for a holiday on the moon. Neither of these predictions have come true yet-but the rapid development of technology may mean these predictions are possible in the years to come.

Space Adventures is currently the only company to have succeeded in sending paying passengers into space. It worked with the Federal Space Agency of Russia and Rocket and Space Corporation Energia to provide flights for the world’s first private space explorers. Each paid over $20 million for their 10-day trip to the International Space Station.

Following successful explorations into space, other companies are now considering the possibility of enabling tourists to visit space. To make it affordable, suborbital space travel is being considered by some companies, like Virgin Galactic. Passengers would be transported to a height of between 100 and 160 km above earth, experience 3 — 6 minutes of weightlessness and a view of the stars before back to earth. This is expected to cost around $200, 000 per person.

Whilst it could be an enriching experience, there are some disadvantages. Many critics say that a huge growth in the spaceflight industry could drastically speed up the process of global warming. The ozone layer would be damaged further and the polar regions would suffer. In addition, space travel is only really affordable for the super-rich, though Virgin Galactic claims to be ‘opening space to the rest of us’.

6 . Most of the 20th century has been a development on the Industrial Revolution taken to an extreme（极端）: people now own more products than ever before; there are enough nuclear weapons to destroy the earth several times over; there is hardly any forest left and pollution has got to the point where we buy water. Within a few years I predict you will be able to buy air—there once was a time when you didn't need to buy food or shelter either.

Important developments in the last century are the breaking down of the class structures left over from the Industrial Revolution stage, bringing with it the empowerment（授权）of the "common man": the working day is set by law to only 8 hours a day; everyone has the vote; the media has less obvious government control; people have landed on the moon, sent spacecraft to Mars and so on. Families have also been shrinking; the nuclear family came about, and especially in the last half of the 20th century, one-parent families are becoming more common. The smaller size of the family shows the increased independence of people—once upon a time people had to live in large groups to survive.

Humans have realized their personality and independence and taken their control of the world to an extreme. In many countries the land is almost completely used in the production of food and as living space. People live in small cities which are entirely human constructed ,made from materials which are also entirely human constructed（concrete bricks）with hardly any remains of nature. Weeds are poisoned because they are messy; even parks have trees grown in tidy lines; grass is mowed to keep it short and soon. I think the massive drug "problem" troubling people is a result of too much of this influence, humans needing to escape the dull world they have created by entering fantasy worlds.

Over the last 100 years, the 20th century consciousness has spread throughout the world. Most of Asia has been thoroughly "Westernized", and most of the Third World is being over-run by Western ways of doing things and living.

7 . Forging a 5G future

The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G? It's the latest generation of cellular (蜂窝状的) network technology.     1    

5G's benefits mainly come from speed and connectivity (连接).    2    People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.

    3     For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒).    4     It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors’ movements.

So what about 5G's connectivity?       5    . Imagine having a smart home that automatically turns the lights on when you open your front door.

"New things become possible when you can move information at a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler. "

No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.
