Dear classmates,
It’s a pleasure for me to have a chance to make a short speech today.

Some Americans judge success on the length of his vacations. The man who gets a month’s vacation each year consider himself more successful than the man gets two weeks. Many people want to be teachers because it are teachers who can get three-month vacation every year. Some college teachers who teach the three classes consider themselves less successful than that who teach only one or two, or none in all. In short, the less work Americans do, the less successful they consider themselves.
We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. 1. .
So, you have to give a speech—and you are terrified. You get nervous, you forget what you want to say, you stumble（结结巴巴） over words, you talk too long, and you bore your audience. Later you think, “Thank Goodness, it’s over. I’m just not good at public speaking. I hope I never have to do that again.”
Cheep up! 2. . Here are some simple steps to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion? Why are you speaking? Then, gather as many facts as you can on your subject. Spend plenty of your time doing your research. Then spend plenty of your time organizing your material so that your speech is clear and easy to follow. Use as many examples as possible, and use pictures, charts, and graphs if they help you make your points more clearly. 3. . Don’t talk down to them. Treat your audience with respect. They will appreciate your thoughtfulness.
Just remember: Be prepared. Know your subject, your audience, and the occasion. Be brief. 4. . And be yourself. Let your personality come through so that you make person-to-person contact with your audience.
If you follow these simple steps, you will see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to make more speeches! You’re not convinced yet? 5. .
A. It doesn’t have to be that bad.
B. Take several deep breaths before your speech.
C. This article gives some advice on how to give a good speech.
D. Say what you have to say and then stop.
E. Don’t give a try to say what you aren’t familiar with.
F. Never forget your audience.
G. Give it a try and see what happens.
Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透镜）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (发电机) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.
So keep dreaming and inventing. One day you might get it right.

Cutting global warming pollution would not only make the planet healthier, it would make people healthier too, new research suggests.
Cutting carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies released Wednesday and published in a special issue of The Lancet British medical journal.
“Relying on fossil fuels leads to unhealthy lifestyles, increasing our chances for getting sick and in some cases takes years from our lives,” US Health and Human Services Secretary Kathleen Sebelius said in a telecast (电视广播) briefing from her home state of Kansas. “As greenhouse gas emissions go down, so do deaths from cardiovascular (心血管的) and respiratory diseases (呼吸疾病). This is not a small effect.”
Instead of looking at the health ills caused by future global warming, as past studies have done, this research looks at the immediate benefits of doing something about the problem, said Linda Birnbaum, director of the US National Institute of Environmental Health Sciences.
Some possible benefits seemed highly speculative (投机的，推测的), the researchers conceded (承认，给予), based on people driving less and walking and cycling more. Other proposals studied were more concrete and achievable, such as reducing cook stoves that burn dung (粪便), charcoal and other polluting fuels in the developing world.
And cutting carbon dioxide emissions also makes the air cleaner, reducing lung damage for millions of people, doctors said.
“Here are ways you can attack major health problems at the same time as dealing with climate change," said lead author Dr. Paul Wilkinson, an environmental epidemiologist at the London School of Hygiene and Tropical Medicine.
Wilkinson said the individual studies came up with numbers of premature deaths prevented or extra years of life added for certain places.
For example, switching to low-polluting cars in London and Delhi, India, would save 160 lost years of life in London and nearly 1,700 in Delhi for every million residents, one study found. But if people also drove less and walked or biked more, those extra saved years would soar (高耸，高涨) to more than 7,300 years in London and 12,500 years in Delhi because of less heart disease.
1.What does the passage mainly about?
A. How can people live longer.
B. Cutting carbon dioxide emissions saves life.
C. Global warming threatens people’s lives
D. People should stop relying on fossil fuels
2.The new research differs from past studies in that ________.
A. it focuses on the immediate benefits of cutting carbon dioxide emissions
B. it studies the bad effects arising from future global warming
C. it is believed by most people
D. it mainly targets at developing countries
3.According to Kathleen Sebelius ________.
A. sometimes it takes years to see the bad effects caused by consuming fossil fuels
B. without greenhouse gas emissions, people would not die of cardiovascular and respiratory diseases
C. the main reason why people get sick is that they rely on fossil fuels
D. death from cardiovascular and respiratory diseases are closely related to greenhouse gas emissions
4.It can be inferred from the passage that ________.
A. London and Delhi have already benefited from reducing greenhouse gas emissions
B. switching to low-polluting cars would save 160 lives in London every year
C. walking and biking instead of driving will reduce the chance of heart disease
D. attacking health problems and dealing with climate change are contradictory
