Every year in China, a day is set aside to honour, and show respect for, the elders and senior citizens in the entire nation. As China has more than 297 million people     1     (age) 60 and over, according to the latest statistics, this day     2     (grow) in popularity over the years.

In the early 1980s, the Chinese government declared that the Chongyang Festival would be the day     3     we celebrate the lives of China’s elder citizens.

On this day, the government and local communities hold     6     (variety) activities for the elders, like free hair-cuts, cultural performances and health-care consultations.

Apparently, respect for the elders is the     9     (found) of the Chinese moral system. Today, throughout China, we find many examples of young people     10     (carry) on this tradition of respect.

4 . Nowadays, the world is slowly becoming a high-tech society and we are now surrounded by technology. Facebook and Twitter are innovative tools; text messaging is still a somewhat existing phenomenon and even e-mail is only a flashing spot on the screen when compared with our long history of snail mail. Now we adopt these tools to the point of essentialness, and only rarely consider how we are more fundamentally affected by them.

Social media, texting and e-mail all make it much easier to communicate, gather and pass information, but they also present some dangers. By removing any real human engagement, they enable us to develop our abnormal self-love without the risk of disapproval or criticism. To use a theatrical metaphor (隐喻), these new forms of communication provide a stage on which we can each create our own characters, hidden behind a fourth wall of tweets, status updates and texts. This unreal state of unconcern can become addictive as we separate ourselves a safe distance from the cruelty of our fleshly lives, where we are imperfect, powerless and insignificant. In essence, we have been provided not only the means to be more free, but also to become new, to create and project a more perfect self to the world. As we become more reliant on these tools, they become more a part of our daily routine, and so we become more restricted in this fantasy.

So it is that we live in a cold era, where names and faces represent two different levels of closeness, where working relationships occur only through the magic of email and where love can start or end by text message. An environment such as this reduces interpersonal relationships to mere digital exchanges.

Would a celebrity have been so daring to do something dishonorable if he had had to do it in person? Doubtful. It seems he might have been lost in a fantasy world that ultimately convinced himself into believing the digital self could obey different rules and regulations, as if he could continually push the limits of what’s acceptable without facing the consequences of “real life.”

5 . Tackling lonely emotions

Do you feel lonely? The World Health Organization (WHO) recently addressed loneliness as a pressing health threat.     1    

Loneliness is a state of mind marked by feelings of isolation despite wanting social connections. So people who are lonely usually experience the emotional pain of not being connected with others.     2     People who enjoy spending time by themselves continue to maintain positive social relationships that they can return to when they want connection.

Social isolation impacts the health and well-being of all age groups across the world.     3     Between 5 and 15 percent adolescents experience loneliness, but the numbers are likely to be underestimations, said the organization.

Social disconnection in adolescence can lead to poorer education outcomes, since young people who have experienced loneliness in high school are more likely to drop out of university. Lack of social connection carries a risk of early death equivalent to other better-known risk factors such as smoking, obesity and air pollution, or potentially even greater.     4     but previous studies have shown that loneliness has been linked to anxiety and depression and can increase the risk of heart disease by 30 percent. A 2015 study looked at the immune systems of its participants who were identified as lonely. It showed that they tend to have more inflammation(炎症) and less immunity.     5    

To tackle this crisis, the WHO launched the Commission on Social Connection, which held its first leadership meeting to outline solutions to build social connections at scale.

A．The following aspects are something concerning how to tackle loneliness.

B．It called for countries and organizations to make social connections a priority.

C．Solitude (独处) on the other hand, is voluntary.

D．It can be a result of feeling stressed due to loneliness.

E．According to the WHO, one in four old people experience social isolation.

F．Loneliness cannot be identified as a fatal emotional factor,

G．Loneliness not only has a far-reaching impact comparable to smoking up to 15 cigarettes a day according to a 2017 study.

8 . The rapid increase of the oil price has brought the world to its senses. Scientists are seeking suitable alternative (替换) but so far in vain. They are considering how they can make better use of the two other major fuels, coal and natural gas, but they have found that neither can replace oil in their economics. In recent years, there has been a growing concern for the environment and coal is not a popular fuel with environmentalists. Natural gas, the purest of the three fuels, is also the most limited in supply.

The answer would seem to lie in nuclear power stations. They need very little fuel to produce enormous amounts of power and they do not pollute the atmosphere. Their dangers, however, are so great and the costs of building them are also high. Not only could one accident in a nuclear power station spread as much radioactivity (放射物) as a thousand Hiroshima atom bombs, but the radioactive waste from these stations is extremely dangerous.

Scientists have recently turned their attention to natural sources of energy: the sun, the sea, the wind and hot spring, of which the sun seems the most promising source for the future. Houses have already been built which are heated entirely by solar energy. However, solar energy can only be collected during daylight hours, and in countries where the weather is unreliable, an alternative heating system has to be included.

However, many scientists are optimistic that new ways of generating large amounts of energy will be successfully developed, but at the same time they fear the consequences. If the world population goes on increasing at its present rate, we may, in fifty years’ time, be burning up so much energy that we would damage the earth’s atmosphere. By raising the temperature of the atmosphere,we could melt the Arctic and Antarctic ice-caps and change the pattern of vegetable and animal life throughout the world——a frightening possibility.

1. What does the underlined phrase “in vain” in Paragraph1 mean?

A．without doubt

B．without results

C．in progress

D．under attack

2. The natural gas cannot take the place of oil because       .

A．it is too pure	B．the source of it is limited
C．its price is increasing	D．it may cause more pollution

3. Which of the following will cause pollution to the environment?

A．coal

B．natural gas

C．wind energy

D．solar energy

4. Nuclear power cannot take the place of the oil because       .

A．it may pollute the atmosphere

B．it cannot generate large amounts of power

C．it may use up enormous amounts of fuel

D．it may cause great danger to us if not properly handled

10 . Social media has completely taken over everyday life, affecting how society runs and changing individuals in ways that even they can feel. While social media can act as a platform for people to express themselves, it can also be overwhelming, especially for high school teens.

To teenager Bryson Lan, quitting social media helped eliminate (消除) a significant distraction in his routine and keep up with teachers. “I was scrolling through social networking sites so much,” Lan said. “I was also starting to struggle since I entered my high school year. When school started, I was super overwhelmed (不知所措的), and I was just not ready for it.”

Most teenagers fear that by eliminating these apps, they will miss out on connections with their peers and feel a significant loss to their social life. However, Lan found he didn’t miss anything during his time without social media.

Another problem with social media is the amount of “junk content” posted. People are regularly posting and updating on social media, and much of the content has no meaning to other viewers and is ultimately a time suck.

However, social media isn’t all negative. Social media can be a place to develop passions and boost creativity. For example, Lan found his interest in photography blossom after seeing works from other photographers on social media. “Social media is a good place where you can have a portfolio (作品集) or upload your works,” Lan said. “A lot of people have photography accounts or art accounts. In some ways, I think it actually furthers your hobby.” “Thanks to this revolutionary development of social media, we can enjoy a world where everyone is closer than before,” Lan said. “But we also need to have the skills to make good use of social media, and that depends on each person’s efforts.”

1. What did getting rid of social media bring Lan?

A．More distractions.	B．Confusion about life.
C．A smaller social circle.	D．More attention on his studies.

2. What does the underlined phrase “a time suck” in paragraph 4 mean?

A．A waste of time.

B．A timetable.

C．A lack of time.

D．A time switch.

3. What’s Lan’s attitude towards social media?

A．Doubtful.

B．Unclear.

C．Objective.

D．Supportive.

4. What’s the main idea of the text?

A．Most teenagers’ opinions on social media.	B．The effects social media has on teenagers.
C．Innovative development of social media.	D．The problems social media brings people.
