[简答题]The greatest results in life are usually attained by simple means, and the exercise of ordinary qualities. 1. The common life of every day, with its cares, necessities, and duties, affords ample opportunity for acquiring experience of the best kind: and its most beaten-paths provide the true worker with abundant scope for effort and room for sell-improvement. The road of human welfare lies along the old highway of steadfast well-doing: and they who are the most persistent, and work in the truest spirit, will usually be the most successful.
Fortune has often been blamed for her blindness; but fortune is not so blind as men are. Those who look into practical life will find that fortune is usually on the side of the industrious, as the winds and waves are on the side of the best navigators. In the pursuit of even the highest branches of human inquiry, the commoner qualities are found the most useful--such as common sense, attention, application, and perseverance.
2. Ge

E-mail
Imagine being able to send a letter to someone, anywhere in the world, that included pictures and sounds as well as written words, and not even have to put a stamp on it. With e-mail you can do just that. E-mail allows you to send messages quickly and easily to other people using computers rather than the postal service. To the Internet user, the ordinary post is known as "snail mail" because it is so much slower than e-mail, which can deliver its message to the other side of the world in seconds.
In some ways, e-mail is like a cross between a letter and a telephone call. You type a note or a letter on your screen and then you send it down the telephone line to another person for as little as it costs you to call your service provider. Whether your message is going to Calgary in Canada or to Copenhagen in Denmark, it will cost the same. You can even attach a file from your computer, whether it be a sound, an image or a text, to your e-mail m
