[1]Although known as an extraordinarily successful businessman, Warren Buffet comes off as a pretty ordinary person.
[2]Looking back on his childhood, one can see how serious he was about making money. Buffet used to go door-to-door and sell soda pop. Later, he also worked at his grandfather’s grocery store. At the ripe age of 11, Buffet bought his first stock(股票). When his family moved to Washington D.C., Buffet became a paperboy for The Washington Post. While still in school, he was making $175 a month, a full-time wage for many young men.
[3]From the beginning, Buffet made his fortune from investing. He started with all the money that he had made from selling pop, delivering papers and so on. Between 1950 and l956, he grew his $9, 800 to $14, 000．From there, he organized investment partnerships with his family and friends, and then gradually drew in more people through very attractive terms.
[4]Buffet applied to Harvard Business School but , making it to be one of the worst admission decisions in Harvard history. The outcome ended up affecting Buffet’s life deeply, for he ended up attending Columbia Business School, where he studied under Benjamin Graham, the father of securities analysis who provided the foundation for Buffet’s grand success.
[5]Buffet is a person of habit—same house, same office, same city. He doesn’t collect houses or cars or works of art, and he hates companies that waste money on such goods. Instead, he has established the Buffet Foundation, with a detailed plan on how to invest his money more wisely to society. What kind of person is Buffet according to Paragraph 1?

Electrical devices（仪器）could soon use power make by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking . British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this , the device helps with the slowing sown movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device . Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers（起博器）. It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.
The developers hope the device will one day help developing countries. Nearly twenty five percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from walking. The knee device does not produce as much electricity as the bag . But the bag requires the walker to carry a load of twenty to thirty kilograms.The second paragraph mainly talks about .
| A．who developed the device |
| B．how the device works |
| C．several possible uses for the devices |
| D．how much electricity the device can produce |
What is the disadvantage of the experimental version of the device?
| A．It is too heavy for the walker to bear |
| B．It is too complex for people to use |
| C．It is too expensive for most people to afford |
| D．It will slow down one’s walking speed. |
Compared with the device designed by Larry Rome ,this new device .
| A．produces power without adding more loads to the walker |
| B．can produce more power in a much shorter time |
| C．needs to be equipped with a battery |
| D．can help the walker walk faster |
From the passage, we can learn that the electrical device can .
| A．help housewives operate the washing machine |
| B．make it much easier for us to go online |
| C．produce more electricity than that invented by Larry Rome |
| D．be applied to operate heart pacemakers |
What would be the best title for the passage?
| A．First device powered by walking will soon be on the market |
| B．Advanced technology brings in a new way to operate heart pacemakers |
| C．Device gives new meaning to the idea of power walking |
| D．Human energy will become a main source of electricity |
While applying to college may seem easy, getting in can be tough! When you apply for college, you will have to be honest with yourself and do a bit of research to find the right fit. Here are three steps to take when applying to colleges for the best chances at getting into the best college for you.
Step l: Making A List Of Colleges To Apply To
With over 6,000 colleges in the United States, the first step in applying to college is to do some research and make a college list . This process will be different for everyone. The number of colleges you apply to can vary, from applying to 1 school (not recommended) to 30 schools (not recommended),each applicant can choose how many colleges they apply to. Many limit the number because applications are accompanied by a fee. .
Step2: Splitting The List Into Target, Reach and Safety Schools
In general, students will want to apply to three types of schools: Target, Reach and Safety schools. It is up to you how many applications you send, but a good mix would be more target than reach, and at least one safety. You will need to take your list, and now decide which are your top picks, which are attainable for you academically, which are affordable for you only with aid, and refine your broad list into a group of schools that gives you the best chance for success. Talk to an admissions counselor at your high school if you have questions about this.
Step 3: Completing and Sending Applications to Colleges
Once your list is complete you are ready to apply to college by completing and sending in applications! College applications take time to complete —you have to write essays, ask for recommendations and get test scores sent to schools—so stay organized！ All colleges will require these types of application materials, so start thinking about these items well before October or December. Once you complete and send them, then you have successfully applied to college.It can be learned from the first paragraph that_____________.
| A．you should be cautious to pick up the right college |
| B．you don't have to think twice before applying to college |
| C．once you apply to a college, you'll be admitted to it easily |
| D．each applicant should choose the best college for their ideal |

| A．needn’t consider about your ability |

| B．Refer to admissions counselor at high school if necessary. |
| C．One doesn't have to send his test scores to the intended college. |
| D．Teachers' recommendations are included in application materials. |
We can conclude from the text that____________.
| A．each applicant has the right to apply to any colleges for free |
| B．the more college one chooses, the more successful he will be |
| C．applicants should send required materials before the deadline |
| D．safety schools are those that don't have so many requirements |
The text is mainly about____________.
| A．how to succeed in life | B．how to apply to college |
| C．how to ask for information | D．how to do a research in college |
While nature lovers across the world wish all humans to realize the significance of their natural surroundings , many Australians are turning caring for the environment into a way of life.
Julie Astonis , an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia’s Brisbane in April, one can still watch colorful blooming （盛开的）flowers in Julie’s little garden.
