Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped(fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

【小题1】According to the passage, many lonely singles don’t appreciate the regular dating scene because it is ___．

If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different.       

If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses.

Here is an example, which I heard at a nurses' convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps over to a table by himself. "Who is that?" the new arrival asked St. Peter. "Oh, that's God." came the reply, "but sometimes he thinks he's a doctor."

If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it'll be appropriate for you to make a passing remark about the inedible canteen food or the chairman's notorious bad taste in ties. With other audiences you mustn't attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system.

If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently off-the-cuff(即兴的)remarks which you can deliver in a relaxed and unforced manner. Often it's the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark.

Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don't succeed, give up" or a play on words or on a situation. Search for exaggeration and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.

To make your humor work, you should ________.

A. take advantage of different kinds of audience

B. make fun of the disorganized people.

C. address different problems to different people.

D. show sympathy for your listeners.

The joke about doctors implies that, in the eyes of nurses, they are ________.

A. impolite to new arrivals.　　      

B. very conscious of their godlike role.

C. entitled to some privileges.　　 

D. very busy even during lunch hours.

It can be inferred from the text that public services ________.

A. have benefited many people.　　    

B. are the focus of public attention.

C. are an inappropriate subject for humor.　

D. have often been the laughing stock.

To achieve the desired result, humorous stories should be delivered ________.

　　A. in well-worded language.　            B. as awkwardly as possible.

　　C. in exaggerated statement.　　         D. as casually as possible.

The best title for the text may be ________.

A. Use Humor Effectively.　　           B. Various Kinds of Humor.

C. Add Humor to Speech.                 D. Different Humor Strategies.

A．Try to stay friendly                               B．Look nice and neat
