    A speech is a wonderful opportunity to inform,persuade or entertain.The best speeches often take on a combination of all three of these components（组成部分）.However,before you can go about the writing of a great speech,it is important to set goals.Goals keep you,your speech and your audience focused.

What a goal is

    In the context of a speech,a goal is the purpose of the speech,and what it hopes to accomplish.For example,the goal of a eulogy（颂歌）might be to celebrate the life of a loved one.The goal of a speech at a political gathering would be to inform the crowd about the political position of a candidate and persuade them to vote and campaign for the candidate in question.

    Why a goal is important

    Without a goal,a speech is without direction.The goal informs the structure and content of the speech.For example,if a speech's goal is to convince people that smoking is bad for them,the speech will be structured with persuasive arguments to back up the goal.A speech with a goal of informing audience will keep the information fair and factual.

    A goal is incredibly important to the speech's ability to connect with an audience.If the speaker is unaware of the goal of the speech,the audience will likely be unaware as well.This severely reduces the effectiveness of the message.

    Besides informing the audience of the content and structure,a speech's goal drives the speaker to greater heights. If a speaker is asked to speak on a specific subject but never establishes the goal,they won't know where to start in the research,organizing and writing of the speech.

    If you have been charged with delivering a speech,establishing a goal can seem difficult at first.There are several things to take into consideration.First,think about who you will be speaking to.The demographic（人口统计）of your audience will likely determine whether you will be able to persuade them or whether they will be able to sit through（一直坐到……结束）.Second,think about the topic itself.If the topic is something controversial（有争议的）,it may worth your while to consider an informative approach to present both sides of the issue.Finally,consider your resources.A speech with an informative or persuasive goal usually requires a great deal of research,and sometimes takes more time to write.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who findsit.

    Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce Peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

Frank, Aged 21

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

David, Aged 19

    I'm not going to lie. The first day is kind of frightening（令人恐惧的）. But you'll get used to it. Don't be afraid of anyone; upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

    So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.

    It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

    The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

    "This explains most of the previous failures of drug trials against rhinovirus," study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

    Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

    With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

Richard Holmes, a British author and academic, is something of a Romantic, famous for biographies of Percy Bysshe Shelley and Samuel Taylor Coleridge. In his last book, "The Age of Wonder", he wrote about science and Romanticism and their common commitment to discovery. In his new book, "Falling Upwards", he combines the two again to tell the stories of Europe's early balloonists (气球飞行者).

Mr Holmes's love of balloons was aroused at a village festival and his enthusiasm is one of the book's many pleasures. He refers to the cheerful tone used in many first-hand ballooning stories, and applies it in this second-hand account. He describes men and women wrapped up in fur coats under their hydrogen-filled balloons, enjoying cold chicken and champagne and looking back to earth to see mankind "for what it really is."

Mr Holmes makes much of the strange side of ballooning, but the book is at its best when examining its more serious applications. In the American civil war, for example, both North and South put observers in balloons to spy on enemy movements. And during the Prussian attack on Paris in 1870-71， balloonists managed to fly out of the city to communicate with the French government in exile (流亡) in Tours.

"Falling Upwards" contains much of the historian's writing characteristics, such as footnotes and bibliography (文献书目), but its epilogue (后记) refers modestly to what has gone before as "a series of true balloon stories". It does touch on the more technical aspects of ballooning, and says little about the French Montgolfier brothers who are credited as its inventors. That though seems a small price to pay for such a spirited work. Mr Holmes's tale ends at the start of the 20th century when the business of flight was being handed over to the airship and the airplane.
