（一）Fire Prevention on Campus
People are alarmed by the succession of campus fires in recent years. In each of these accidents, heavy casualties were reported – houses were burned down, students lost their lives, and properties were damaged. Faced with such a chilling fact, people keep asking, “What on earth results in these repeated tragedies?”
A brief survey of them reveals that human factors still prove to be the leading causes. For example, three of these fires were caused by the students’ use of electric water-heaters. As students often leave the heaters unattended, the risks are rather high should the water in the bottle boil dry while no one is around to turn off the power. In other cases, fires were also caused by stoves, candles, cigarette butts, etc.
Since most of these disasters could have been prevented if proper precautions had been taken, students should be better educated on the importance and measures of fire control. The following three reminders are of particular importance for us students: First, learn how to use a fire extinguisher. Second, double-check candles, heaters, stoves and other electric appliances, and make sure there are no open flames before leaving rooms. Lastly, do not smoke in the dorm.

（二）Enhance Awareness to Guard against Campus Thefts
“If you don’t want to wake up and find you have no pants to wear, you’d better put them on in sleep,” goes a popular joke among students. Obviously, campus thefts have become increasingly annoying as they occur far more often than before. And it seems that the thieves are less choosy these days, with their targets ranging widely from bikes, cell phones, purses, pre-paid IC cards to sunglasses, bags, and even underwear. In short, anything that worth a dime is likely to be stolen.
What makes students the easy targets? The reasons are not hard to find. But I believe of all these reasons, the lack of anti-theft alertness is the most important. For lack of alertness, the students tend to leave the doors and windows wide open during sleep at noon or at night in summer. For the same reason, they’ll also leave their bikes unlocked before a store or by a road, or forget to take away their personal stuff before they go out of the classroom to make a phone call. These acts undoubtedly have increased their exposure to the light-fingered monsters.
In order to minimize possible losses, the students must stay on guard in the first place, as awareness of the thefts around often makes a big difference. To be more specific, the students should not hide any tempting amount of cash in the dorm. Put it in the bank instead. Besides, do not leave any valuable items unattended. Take them wherever you go. In addition, it’s advisable to develop a neighbourhood watch programme with other students in the dorm and neighbouring dorms.

（三）How Will Our Life Go on without Internet?
If asked whether the Internet is the greatest discovery of the 20th century, my answer would be yes. The Internet has drawn the world closer together, realized countless incredible dreams, and provided modern people with a great many conveniences and a brilliant life.
Today, many people simply feel they cannot live without the Internet. Governments publish their latest policies and decisions online for worldwide recognition. Political campaigns are often done online to gain wider public support. Companies and enterprises resort to the Internet for more business opportunities and potential customers home and abroad. Universities and researchers turn to the Internet if they’d seek international cooperation or funding. Common folks like us also rely on the cyber world in various ways, for communication, entertainment, banking and shopping.
True, the power of the Internet is all pervasive and its many negative effects are already visible. For example, Internet addicts tend to withdraw to their own fantasy world rather than communicate with a real person. Children are exposed to online pornography and violence. Internet frauds are an everyday occurrence. In view of all this, you are advised to use the Internet with wisdom. Keep it at a safe distance and never lose yourself.
has drawn…, realized, and provided此为谓语连动式的运用。
As a primary source of information as well as an efficient means of communication, the Internet offers people a colourful and convenient life. Just by clicking the mouse, we can enjoy a brilliant and easy life that could not be achieved ever before: shopping, making friends, contacting relatives, looking for jobs, downloading music and movies, conducting business deals, and freely airing our opinions.
For its convenience, the Internet has attracted people like magnets and some people even claim that it is indispensable. To them, life can’t go on without it. Every day millions of people spend hours on end surfing the Internet. They are obsessed with it so much so that they forget many other important matters.
As for me, I don’t approve of unrestrained Internet reliance. Although the Internet is a gift of the technological revolution and a blessing of this information age, we should never let it control our life. The Internet absolutely doesn’t mean the whole world to us. Instead, we should guard against its negative effects. To those Internet addicts, I would add: “Self-control can make or break your life. With proper use, the Internet serves you; otherwise, it kills you.”
