Nowadays, it is common that more and more high school students open their own micro blogs on the Internet. For one thing, it can provide a colorful platform to show their talent. For     1    , it is a useful way     2    （release） their pressure. And all these make it more and more popular with high school students.     3     many parents and teachers hold a different view. They think that     4    （manage）one’s micro blog will take a lot of time and energy,     5     should be used to study.

In my view, I am greatly in favor of this activity. Today the Internet is playing     6     important role in our life. Therefore, as high school students of the Information Age, we need to learn to make use of this valuable tool to communicate and display ourselves. What’s more, opening and organizing micro blogs need     7    （vary） abilities such as writing, designing, being skillful at computer and so on. Only if we master those abilities can we make a successful micro blog. As a result, we improve ourselves while     8     （organize） our micro blogs.

In fact, micro blog     9     （it） is of little harm. It is your attitude     10     it that matters. We should take the advantages and avoid some bad effects.

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. Of course, showing respect and admiration to     4     old is a Chinese tradition     5     (date) back to ancient times, and therefore the people easily and readily support this day. 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.

However, respect for the elders should     7     (keep) in mind firmly and not restricted to one special day only. According     8     historical records, elders over 70 years old enjoyed special treatment and anyone not showing respect to them would be punished, which proves that respecting the elders was set in law back then.

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.

7 . 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.
