Great changes have taken place in the way of communication in people's life in recent years.
In the past, people kept in touch with each other mainly by written letters or using the public telephone. But now almost everyone have his own mobile phone. People can communicate for each other almost at any place and at any time. What's more, people have easy access to the Internet, what enables them to send and receive e-mails whatever they like.

Common public speaking problems
The use of "I feel", "I think" and "maybe"
In the question-and-answer session of the speaking competition, many contestants began their answers with uncertain expressions like "I feel", "I guess", "I hear", "maybe" and "perhaps".
These words show that the person is only speaking from his or her point of view.1.
Work on keeping your answers brief and to the point, 2.. Instead of the empty-sounding "I guess", using facts, together with a clear conclusion based on those facts, is far more likely to be popular with an audience.
Using only one speaking style
Don't stick to the same tone.3.
For example, when they spoke about their dreams, some sounded romantic. Others used humor. Very few used several different styles together. Try mixing more than one style, rather than just sticking with the same one.
Irresponsible answers
Public speaking is different from personal conversations. You're responsible for your words. 4.So you should think twice before you talk. Don't be like the student who, when asked about his opinion on book piracy（盗版）, started by saying he supported it.
Talking around the topic rather than directly answering it
You should focus on one point and give a clear solution. The key is to work out what question is being asked. Is it asking you to discuss a certain topic or to present your own point of view?
Use one or two arguments together and give a strong conclusion.5.
A. It can be boring. Try to mix it up.
B. Even though you want to answer quickly, you don't want to sound foolish.
C. Also work on delivering them with calmness and confidence.
D. Deliberate gestures and affected（做作的）expressions of feelings are improper in a successful speech.
E. Remember that judges are not judging you on whether they agree, but on your ability to say what you think clearly.
F. This lacks the support of facts and seems not to be reliable for the judges and audience.
G. Confidence is extremely important in public speaking as it lets a speaker sound more convincing.
In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse（诅咒）;in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets（药丸）that contained mercury（水银）, believing that it would make them immortal, but they died afterward.
Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars（毛毛虫）, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."
A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances（物质）that we regularly ingest（摄入）-chili, coffee and chocolate-owe their special flavors or stimulating（提神的）effects to chemicals that plants make to poison insects.
1.What does the underlined word "immortal" in Paragraph 1 mean?
A. happy B. not moral
C. living forever D. sick
2.What is the main purpose of the exhibition The Power of Poison?
A. To give people more in-depth knowledge about poison.
B. To teach people how to handle poisonous animals.
C. To inform people about which animals are the most poisonous.
D. To show how poison has been used for medical treatment.
3.Which of the following statements about the Golden poison frog is TRUE according to the article?
A. Its skin can cut off the signaling power of your nerves.
B. It's about the size of a coin.
C. It's the most poisonous animal on display.
D. You can only see it in a rainforest setting of the museum.
4.The stimulating effects of coffee come from ________.
A. natural poison made by the plant
B. the substances that we regularly ingest
C. chemicals produced by poisonous insects
D. its special flavor
