单选题Above all know your audience and match what you say to their needs. Creating your presentation with your audience in mind will assure that your audience will follow you. If your presentation doesn't appeal to your audience- no matter how well you have developed your presentation-- your presentation will fall on deaf ears. This leads us to the next rule: Know your material thoroughly. Your material needs to be second nature to you. Practice and rehearse your presentation with friends, in front of a mirror, and with colleagues. If you are speaking in a second language, make sure that you record yourself and listen to a number of times before going to practice with a native speaker (if possible). Remember that you are an actor when presenting. Make sure that not only your physical appearance is appropriate to the occasion, but also the tone you use is well chosen. If your topic is serious, be solemn. However, it's always a good idea to begin your presentation with an ice-breaker. Don't worry about making friends, rather lead the audience through your materials in a calm and relaxed manner. Speak slowly and clearly, and remember to address everyone in the audience - even the person the farthest away from you. To achieve the above goals follow these tips when giving your presentation: 1. Speak with conviction. Believe what you are saying and you will persuade your audience. 2. Do not read from notes. Referring to notes is fine, but do so only briefly. 3. Maintain eye contact with your audience. Making direct eye contact with individuals will help them feel as if they are participating in your presentation. 4. Bring handouts. Don't just use a PowerPoint presentation. Provide audience members with handouts of the most important materials so they can keep your most important takeaways in mind. 5. Know when to stop. This cannot be underestimated. You need to make your case, but continuing for too long will only ensure that the audience forgets what you have said.

单选题 At the heart of the debate over illegal immigration lies one key question: are immigrants good or bad for the economy? The American public overwhelmingly thinks they're bad. Yet the consensus among most economists is that immigration, both legal and illegal, provides a small net boost to the economy. Immigrants provide cheap labor, lower the prices of everything from farm produce to new homes, and leave consumers with a little more money in their pockets. So why is there such a discrepancy between the perception of immigrants' impact on the economy and the reality? There are a number of familiar theories. Some argue that people are anxious and feel threatened by an inflow of new workers. Others highlight the strain that undocumented immigrants place on public services, like schools, hospitals, and jails. Still others emphasize the role of race, arguing that foreigners add to the nation's fears and insecurities. There's some truth to all these explanations, but they aren't quite sufficient. To get a better understanding of what's going on, consider the way immigration's impact is felt. Though its overall effect may be positive, its costs and benefits are distributed unevenly. David Card, an economist at UC Berkeley, notes that the ones who profit most directly from immigrants' low-cost labor are businesses and employers—meatpacking plants in Nebraska, for instance, or agricultural businesses in California. Granted, these producers' savings probably translate into lower prices at the grocery store, but how many consumers make that mental connection at the checkout counter? As for the drawbacks of illegal immigration, these, too, are concentrated. Native low-skilled workers suffer most from the competition of foreign labor. According to a study by George Borjas, a Harvard economist, immigration reduced the wages of American high-school dropouts by 9%between 1980-2000. Among high-skilled, better-educated employees, however, opposition was strongest in states with both high numbers of immigrants and relatively generous social services. What worried them most, in other words, was the fiscal (财政的) burden of immigration. That conclusion was reinforced by another finding: that their opposition appeared to soften when that fiscal burden decreased, as occurred with welfare reform in the 1990s, which curbed immigrants' access to certain benefits. The irony is that for all the overexcited debate, the net effect of immigration is minimal. Even for those most acutely affected—say, low-skilled workers, or California residents—the impact isn't all that dramatic. 'The unpleasant voices have tended to dominate our perceptions, ' says Daniel Tichenor, a political science professor at the University of Oregon, 'But when all those factors are put together and the economists calculate the numbers, it ends up being a net positive, but a small one. ' Too bad most people don't realize it.
