Have you ever forgotten     1     (lock) the door of your house? Or, have you ever forgotten to switch off the TV or computer? These kinds of things happen to us all the time, waste resources, and can sometimes lead     2     problems.

However, in the not-too-distant future, we will     3     (live) in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget.

You will no longer have to think about turning     4     (switch) on and off yourself. Your home will also learn your     5    (day) routine and preferences, so everything will be ready for you when you get home each evening. Your lights will come on     6     instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already     7     (prepare) for you.

In addition, your smart home will be monitoring your health for you every day. If you start to have sleep or weight problems, it will send a warning to your phone. It will also give you suggestions on a     8     (health) diet and     9     to sleep better. Smart toilets will be keeping constant track of your health as well. They can warn you early on if there is something     10     (normal) or if you have a critical illness, such as cancer, and potentially save your life.

Smart homes will be able to prevent serious damage from accidents. Nevertheless, it will take some years before most new homes begin to use this new technology.

The Future Life on Mars

Can you imagine what the future will be like? Some     1     (company) are looking to produce flying vehicles. That is amazing. If we have our own     2     (person) flying cars, we would fly at 480 kilometers per hour, avoiding busy roads. However,     3     seems that there is a long way to go before they get off the ground! One of the problems     4     (point) out by some people is what     5     (happen) if the flying cars break down.

Others are trying to build a practical suit "exoskeleton", a suit of robot arms and legs      6     follows your movement. It will allow the wearer     7     (lift) heavy objects and walk a long way! It is useful in many ways,     8     (especial) for people with disabilities. This suit might help people to walk again after disease and injury. But the disadvantage at the moment is battery life. A suit like this     9     (need) a lot of power but batteries only last about 15 minutes at the moment.

So in the future, whether we may fly to work     10     lift heavy objects, there are plenty of problems to solve before this is possible.

There is no doubt that humankind dreams of making Mars our second home. However, sending people there will require all the skills, courage and     1     (intelligent) of the human race. While the Moon can be reached within days, it would take months to reach Mars,     2     (travel) through dangerous solar radiation. And even if the first settlers do reach Mars safely, staying alive will be     3    daily challenge, but as proved by the Biosphere experiment, not impossible.

As early as the 1980s, scientists were building Biosphere 2 in the Arizona desert. It consisted of a closed space    4     people, animals and plants could live together. The “closed” concept meant that the space was designed     5     (function) with its own oxygen, food and water, needing nothing from the outside world.     6     the two-year experiment was not a success, it did provide us with a better understanding of how humans might be able to live on another planet. More recently, scientists     7     (succeed) in growing a variety of plants in an environment similar to that on Mars. That     8     (definite) is a big step forward.

For now, human settlement of Mars is still     9     (decade) away. In the meantime, scientific research shows that the planet Earth is getting     10     (warm). This change is having a terrible effect on the biosphere.

5G is developing, but most of us aren't really sure what it is or the reason     1     we need it. A big part of the reason is that 5G means more than one thing. If you ask different people, you     2    (provide) with different answers.

Experts believe that 4G is on     3     way out. In 2020, the U.K. is expected to use 5G. At present, it is unknown exactly what influence 5G will have on people's life but it is widely thought that 5G will     4     (definite) be faster than any generation of networks we have used previously.

Work will likely become much easier as 5G will allow quicker downloads and a better ability to work online even if there is no wi-fi connection. With the     5     (develop) of 5G, driverless cars will be able to communicate     6     other vehicles, which can reduce road accidents by about 10%, One of the most     7     (impress) things will be that people can see which seats on a train are accessible to     8     (they) when it arrives at the station.     9     (get) around the world will also be more convenient.

A number of     10     (company) are now working on bringing 5G to the market. It remains to be seen how much of the country 5G will cover and whether everyone will be able to benefit from it.

Cards and digital(数字的) technologies     1    (kill) off cash slowly, but is it a cause for concern? Not     2    (necessary). Here are some ways of making the most of digital finance.

Cash is no longer king. Over recent years fewer and fewer transactions have been made with cash. The most recent figures show coins and notes are used just 34% of     3     time, down from 63% a decade ago. And usage     4    (predict) to fall to just 10% in 15 years.

Instead we’re paying with cards and digital technologies. Some of this is down to user choice, with contactless cards and smartphones making spending     5    (fast) and more convenient.

But it’s also being forced upon us. Some retailers are refusing physical money as they can avoid the high bank charges levied(征收) at them for     6    (handle) cash. Meanwhile it’s harder to get your hands on notes as cash machines and     7    (bank) disappear from the high street. And these are trends which are likely     8    (increase) in the coming years.

This could be bad news if you still primarily use cash,     9     that’s how you pay your bills or how you budget. For some, cash is just what you know. For     10    , cash is a necessity—especially when going digital is the alternative.

As a result this move towards cashless society makes many uneasy.

Chang’e 4 sent a picture    2    ( take) at 11:40 am back to Earth. It shows that the moon’s far side is not    3    (absolute) dark. But it is often called the dark side because it faces away from Earth and little    4    (know) about it. In fact,the far side of the moon is a rather quiet place that is free from disturbance from radio    5    (signal) from the Earth.

Hou Xiyun is a professor at Nanjing University’s school of astronomy and space science,     6    told the Associated Press,   “    7    the whole, China’s space technology still lags behind the West,with the landing on the far side of the moon, we have raced to the front.”

He added，”The landing is    8    example of China’s growing desire     9    (strengthen) its position as an international power.

China plans to explore Mars, Jupiter and asteroids in the future.”

There’s no doubt that our nation will go farther and farther.

It’s hoped     10     our space dream to make China stronger will come true soon.
