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.

Based on the     1    (心理学) behind creating a desire to buy, advertisers have developed ways of persuading people into     2    (购买) their products or services. A common technique to make an impact is to create a     3    (难忘的)     4    (口号).     5    (口号) use simple but impressive language to make us remember the product or service being advertised. Some of these slogans may also appeal to (迎合) our emotions. For example, a slogan may connect a fine china     6    (茶壶) it aims to promote with our pride in having good taste. You will hear a variety of slogans any time you watch TV. Think about your favourite one. What makes it special? And what message does it try to     7    (被传达)? A slogan which communicates an idea effectively can    8    (使增长) sales and even becomes part of popular culture. That is the power of memorable slogans.

Another technique advertisers often employ is to link their company or product to a “    9    (品牌)    10    (大使)”-a famous actor, a sports star, or even a fictional character. Think of a popular fast-food restaurant. Does it have a     11    (品牌大使)? Is the     12    (品牌大使) popular among potential customers? The more we like the brand ambassador, the more we will be attracted to buy the product.

The festival was from the first under the charge of the Eleians. But so liberal a policy did this nation adopt and pursue that people from neighboring states were glad to send competitors. Rapidly the custom of resorting to the games spread to more     1    (遥远的，远处的) states. From an Eleian event, the festival finally became Panhellenic. The Athenians and Thebans at a very early date achieved splendid victories in these games. The Theban Pagondas was crowned victor in the four- horse chariot race in the 25th Olympiad, when for the first time this was a feature of the festival. Thus one state after another turned its     2    (注意，注意力) to the venerable celebration, and if it happened that a citizen of one state was crowned victor in a contest, interest in the games was sure to be increased in that locality.

Even in the absence of positive evidence it would be contrary to reason to suppose that the games were originally established as they existed at the time of Pindar. In fact, the different features were added successively. According to a fairly reliable tradition, there was originally and for 12 following Olympiads only one contest: a foot race     3     of (由……组成) a single lap of a stadium of 200 yards. Boxing and the chariot race are said to have been added in the 23rd Olympiad. Thus the games grew more elaborate, and the time over which they extended was increased from a     4    (仅有一个的，单个的) day to five or six.

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!

The first    1     of friendship is the peace that comes from sharing with friends our joy, sadness, success and failure. Here, friendship has a    2     advantage - happiness takes    3     a greater meaning and a trouble shared becomes a trouble halved!     4    , this kind of openness results    5     a close friendship. With true friends, we feel free to share our joy and sadness in full measure. We know that our friends will both respect our feeling and    6     these moments of closeness. Indeed, the human heart depends on such opportunities for comfort and protection.

Besides such ethical concerns, the legal situations the autonomous vehicle industry is likely to be confronted with have     1     heated debates. In this emerging industry, manufacturing and programming standards are not yet     2    . Moreover, the quality and safety of the technology used in self-driving cars is still being challenged. This could lead to extraordinary cases like who should be held     3     when self-driving cars are involved in accidents — should it be the driver, the software programmer or the manufacturer? Manufacturing and programming standards first have to be agreed upon to make it possible for law courts to decide who is at fault when things go wrong. As     4     in autonomous vehicle design and technology are in progress, the final agreement on laws and regulations     5     this industry remains to be seen.
