Have you ever forgotten to lock the door of your house or switch off the TV? These kinds of things often happen to us,     1     may lead to serious problems.     2    , in the near future, we will be living in smart homes that will lock the door and switch off the TV automatically. These smart homes will provide us    3    a comfortable environment.

Your home will learn your daily routine and    4     (preference), so everything will be ready for you when you get home each evening. For example, lights will come on     5     (instant) you enter the door along with your favourite music. All controls will respond to voice commands, so you just say     6    you want and the home system will obey. Besides, it will give you suggestions on a    7     (healthy) diet and how    8     (sleep) better.

This smart technology is not     9    fantasy. Nevertheless, it will take some years     10    most new homes begin to use it.

The Future Life on Mars

Compared with the life we     1    (live) on the earth now, the future life on Mars will be     2    (total) different.

Firstly, without pollution on Mars, people will be able to drink cleaner water     3     breathe fresher air, so they will be     4    (health).     5     food on Mars will be different from our food now. People will just take     6    (pill) and drink man-made juice instead of eating bread and meat. Secondly, people will travel back to the earth or to other planets for sightseeing by spaceship. Additionally, there will be no     7    (fix) school and classrooms. Children will just fly to the classroom     8     the school spaceships. And people won’t work in factories or companies.     9    (them) can stay at home,     10    (work) with computers.

【推荐3】I am reading 1984 these days, a novel     1     (write) by George Orwell in the 1940s. It occurred to me that in another 84 years, it will be 2100, so I’d like to make a few     2     (predict) for the next 84 years.

First, we will have made certain contact with lives from other planets,     3     will change the way we look at the world and the universe. The most important outcome (结果) of this may be the uniting (联合) of the world.

The development of technology is a certainty. This can have many     4     (differ) outcomes, but it is clear that the new technology will have a major influence     5     human society. Simply     6     (speak), the next 84 years will determine whether humans have a future here on this planet.

We are facing many challenges that are forcing us     7     (choose) whether we will change the way we live     8     die. We must use our technology to bring about a much     9     (good) world. If we are unable to solve our problems     10     (successful), it appears unlikely that we will have much of a future beyond the end of this century.
