Could machines really develop human-like intelligence? And what would happen if they did? Would thinking machines work alongside humans or     1     the existence of humans? How would they be punished if they     2     crimes or even murdered humans? As we become more and more     3     on computers, some scientists are urging us to think about the dangers     4    by the advances in AI. Stephen Hawking, for example, warned, “The development of full artificial intelligence could     5    the end of the human race.

With technologies first researched and developed for space     1    , we can solve some of the big problems facing mankind, making our lives safer and easier. One of these is earthquake shock absorbers. Shock absorbers     2     applied to the space shuttle launch have also been set up in the cities with a high     3     of earthquakes in order to protect buildings and save lives. Some technologies need     4     research to better solve real-life problems. For example, liquid hydrogen is a clean     5     energy source that is used widely as rocket fuel, and it is     6     that hydrogen fuel cell vehicles will be mass-produced and     7     in the near future. These scientific and technological     8     can provide benefits to societies on the Earth in many areas     9     health, energy and information technology. This should be a strong     10     for continuing to explore space.

Because the mass media     1     so many people, it is a perfect     2     for advertisers. If an advertisement is placed on a popular website or on TV at peak times, a huge number of people will know about the product or service it is advertising. In     3     to making people aware of a product or service, a successful advertisement will also create a desire to buy, thus     4     business. That is why when a company wants to promote a product or service, it often launches a mass media advertising     5    .

    6    , such warnings demand our attention. We need to make sure that we will not fall     7     to AI. We may still think it would be     8     to relax all day and allow     9     machines to do all the work for us — but perhaps we should not be too     10     and rather be careful what we wish for!

With the quick spread of COVID-19, more and more people around us are tested p    1    and people grow more and more     2    (焦虑). Here are some effective measures to p    3    you from being infected(感染)with the virus.

First, wear masks wherever you go, though it is not c    4    for you to perform daily routine. Second, m     5    distance from others. It is of extreme importance to avoid direct c    6    with those who have fever, cough or other COVID-19 symptoms(症状). Third, eat properly to ensure you have enough     7    (营养). If you have to eat outside, bringing food from home is     8    (推荐). Last but not least, we should a    9    importance to rest and exercise, which can help you     10    (恢复)sooner if you should fall ill.

At the basic level,     1    intelligence is a branch of computer science that aims to create intelligent machines. One of the     2    aims of AI is to develop computer intelligence capable of learning from experience, adjusting to new     3    and performing tasks like humans. To achieve this aim, many approaches to creating true AI have been put forward, including “deep learning”, which enables a machine to improve its own performance by learning from the results of its previous actions. Deep-learning AI has the capacity to     4    massive amounts of data through multiple layers, imitating the complex     5    of the human brain.
