In order to present the best presentation and eliminate room for error, you need to keep in mind certain guidelines. Here's are some of my ideas for presenting quality presentation that demand genuine attention from your listeners.

Picking out a topic is the hard part, when it comes to choosing from a list of presentation subjects. It has to be interesting, impactful and unique, therefore it is crucial to choose something you care about rather than randomly selecting one. Ask yourself if it covers angles －is it informative? Will it keep my listeners hooked? Will it create an air of boredom? Will I be able to get all my facts and research done? Is it appealing to me, but not to them?

There's nothing more annoying than have someone blabber on about a topic he/she hasn't done extensive research on. It is obvious from the way they speak, how monotonous their tones sound and how robotic their movement and gestures are. So don't be that someone. Take the effort to learn as much as you can. Make it matter to you, and remember how it can impact your listeners, and enlighten them on things they didn't know about at all.

No one is perfect, and there are bound to be mistakes or circumstances that you didn’t count on and couldn’t avoid. You could stutter with a word, mix up slides, or forget some important sheets of your presentation and so on. Straighten up. Crack a minor joke in your defense. In other words improvise and don't beat yourself up about it or else your presentation will end in disaster. Don't let it ruin the rest of it, and finish the presentation as planned, so that people think more of how well it ended.

The best thing about presenting a topic is eye contact. If you are able to say it by heart, and not by looking at a piece of paper, you will have mastered the most effective presentation technique. Memorize your lines, and points, and only glance at your notes occasionally if you think you may forget something. In the end, if you think that you are well prepared to answer questions, then by all means invite them.

Directions: Read the following passage and choose the most suitable heading from A—F for each paragraph. There is one extra heading which you do not need．       
A．The results explained why time passes quickly when we are dealing with more tasks
B．Time flies when you are having fun and drags when you are bored．
C．Volunteers were told to finish three different tasks in the study．
D．There are areas of the brain having the function of estimating time．
E．Concentrating on time passing is probably a more accurate perception of reality
F．Focusing on' the duration or the color the of image makes trips speed．
【小题1】
Scans have shown that patterns of activity in the brain change depending on how we focus on a task． Concentrating on time passing, as we do when bored, will trigger brain activity which will make it seem as though the clock is ticking more slowly．
【小题2】
In the study, 12 volunteers watched an image while researchers monitored their brain activity using MRI scans．Volunteers were given a variety of tasks．In one they were told to concentrate simply on the duration of an image, in another they were asked to focus on the color, and in a third they were asked to concentrate on both duration and color．
【小题3】
The results showed that a network of brain regions was activated when more subjects were paid attention to duration．It is thought that if the brain is busy focusing on many aspects of a task, then it has to spread its resources thinly, and pays less heed（注意） to time passing．Therefore, time passes without us really noticing it, and seems to go quickly．
【小题4】
However, if the brain is not stimulated in this way, it concentrates its full energies on monitoring the passing of time．This may make time seem to drag, but in fact the researchers found that the more volunteers concentrated on the duration of the images, the more accurate were their estimates of its duration．
【小题5】
Lead researcher Dr Jennifer Coull said many of the areas of the brain involved in estimating time were the same that played a key role in controlling movement, and preparing for action．She said this overlap suggests that the brain may make sense of time as intervals between movements, in much the same way as a musician marks time with his foot, or an athlete anticipates the sound of a starter's pistol（手枪）．

I have heard that fluoride can help stop dental decay, but I recently read that it is poisonous．Which of these is true? How can children use fluoride safely?

This question is answered by Dr Marcia M．Rich who practises general dentistry in Newholt．She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares．

My answer to the first question is to stress that fluoride works well and is safe when users follow instructions．Young children have a tendency to swallow toothpaste, which is why they should only have a tiny amount of fluoride toothpaste on their toothbrush．If this simple measure is taken, parents can be confident that children will be protected against tooth decay, and come to no harm.

Almost all medicines have an adverse effect－or even be deadly－if they are not taken as directed．So you are right－fluoride can be poisonous if it is swallowed in very large quantities．It is for the reason that fluoride supplements can only be obtained on prescription from the doctor or dentist．Please be assured that fluoride overdoses are rare－in fact, I have never heard of any fatal incidents related to fluoride poisoning.

Scientific studies have shown that fluoride can help to prevent cavities as long as it is used correctly．If fluoride is abused, there is a risk of illness or even deaths in extreme cases．If a deadly amount of fluoride is taken, immediate first-aid could save a life．A person who has swallowed a large amount of fluoride will probably start vomiting．If not, the patient should be given milk or antacid and taken to the nearest hospital for emergency treatment.

Taking too much fluoride while teeth are growing can lead to a condition called dental fluorosis．The most likely cause is the swallowing of fluoride toothpastes by young children．It can also be caused by inappropriate use of fluoride drop or other fluoride supplements, for example when fluoride is already is already present in drinking water．  

Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.

A. Be well-organized.

B. Close with a Q & A.

C. Don’t be contradictory .

D. Bring it to a specific end.

E. Speak slowly and pause.

F. Drop unnecessary words.

Speaking to a group can be difficult, but listening to a bad speech is truly a tiresome task—especially when the speaker is confusing. Don’t want to confuse your audience? Follow these suggestions:

1.When it comes to understanding new information, the human brain needs a little time. First, we hear the words; then, we compare the new information to what we already know. If the two are different, we need to pause and think. But a breathless speaker never stops to let us think about what he or she is saying and risks confusing us. Slow it.

2.Sometimes we all start a sentence one way and then switch directions, which is very difficult to follow. When you confuse your listeners with opposing information, you leave the audience wondering what part of the information is right and what part they should remember. Instead of relying and keeping correcting yourself, work to get the facts clear and straight.

3.Jumping from point to point as it comes to your mind puts the onus (责任）on your listeners to make up for your lack of organization. And it’s confusing for them to listen, reorganize, and figure out what you’re saying all at once. But going smoothly from one point to the next helps them understand information more easily. You can arrange things from beginning to end, small to large, top to bottom or by some other order. Just be sure to organize.

4.Repeated use of um, ah, like, you know and some other useless noises can drive an audience crazy. It makes the speaker sound uncertain and unprepared, and it can leave listeners so annoyed that they can’t pay attention. Recently I attended a speech that was marked by so many ums that audience members were rolling their eyes. Was anybody grasping the intended message? Um, probably not.

5.Many speakers finish up their speeches with question-and-answer (Q & A) sessions, but some let the Q & A go on without a clear end. The audience is often left confused about whether the meeting is over and when they can get up and leave. Do your listeners a favour by setting a time limit on questions, and close your speech with a specific signal—even if it’s something simple like, “If you have any more questions, you know where to reach me.”

Or even more to the point, conclude your speech with “Thanks for your time. ”
