Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census ( 普查 ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( 花瓣 ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.

1.It is _________ to see a black flower.

2.The passage tells us that ________________.

The Crowne Plaza Copenhagen Towers has been named the greenest one in the world by the travel and tourist organization Skaal International, reported the Danish news agency Ritzau on Monday.

The hotel has been awarded the EcoTourism Award for setting an environmental-friendly example to other hotels, said the report.

The Crowne Plaza Copenhagen Towers is located in the Copenhagen suburb of Oerestad and has the largest solar cell facility in the Nordic. This facility delivers energy to the hotel while Danish groundwater supplies cooling and heating in the air condition of the hotel.

TV and lights in the hotel are all of energy-saving brands. Shampoo bottles, toothbrushes and washing accessories are biologically degradable, which means that the nature can easily absorb the materials.

The hotel restaurant is only buying local goods and the food leftovers are used for bioenergy as well as fertilizer. The fitness facilities also provide a green touch to the hotel, as the training bikes of the fitness center are linked to the power grid（电网） of the hotel, thereby providing free energy if any guest wishes to exercise. People who do contribute free energy this way are supposedly getting a free meal in the hotel restaurant. “It is the first time that a Danish hotel receives this award. I think our throughout green thinking is the reason why we have been awarded. It is all the small details, as well as the big picture，” says Allan Agerholm, the CEO of the hotel, in a press release.

?The Crowne Plaza Copenhagen Towers opened its doors last year. Skaal International was founded in 1932 by travel managers and has approximately 20,000 members in 89 nations. It is an organization promoting global tourism.

The literal meaning of philosophy is “love of wisdom”. But this meaning does not tell us very much. Unlike the other disciplines, philosophy cannot be defined by what you study, because it is actually unlimited. Anything can be the subject matter of philosophy: history, law, language, literature, mathematics, and in fact, the other academic disciplines are directly related to philosophy. For this reason you get a Doctorate of Philosophy (Ph. D.) in biochemistry, or computer science, or psychology.

      Two broad sub-fields of philosophy are logic and the history of philosophy. Logic is the science of argument and critical thinking. It provides sound methods for distinguishing good from bad reasoning. The history of philosophy involves the study of major philosophers and periods in the development of philosophy.

      Of what use is philosophy? First it is useful in educational advancement. It is necessary for understanding other disciplines. Only philosophy questions the nature of the concepts used in a discipline, and its relation to other disciplines. And through the study of philosophy, one develops sound methods of research and analysis that can be applied to any field.

      There are a number of general uses of philosophy. It strengthens one’s ability to solve problems, to communicate, to organize ideas and issues, to persuade, and to take what is the most important from a large quantity of data. These general uses are of great benefit in the career field, not necessarily for obtaining one’s first job after graduation, but for preparing for positions of responsibility, management and leadership later on. It is very short-sighted after all, to take a course of studies only for the purpose of getting one’s first job. The useful skills developed through the study of philosophy have significant long-term benefits in career advancement. No other discipline systematically follows the ideals of wisdom, leadership, and capacity to resolve human conflict.

According to paragraph 1, philosophy can best be described as the study of        .

A. social sciences                          B. natural sciences

C. both social and natural sciences        D. the subject matter of politics

What does “discipline” mean in the first paragraph?

A. subject                     B. science                     C. literature           D. occupation

With the study of philosophy, you can           .

A. become a great leader                                  B. succeed in everything

C. find a good job soon after graduation     

D. make progress in your career development

According to the passage, which of the following statements is TRUE?

A. Philosophy is an independent discipline.

B. Logic helps you to become a better thinker.

C. The study of philosophy brings you immediate benefits.

D. The meaning of philosophy is too limited to define.

From the passage, we can conclude           .

A. not all the subjects have to do with philosophy

B. a person will get a Ph. D. if he/she studies philosophy

C. philosophy can be helpful for the study of any other subjects

D. philosophy is the only solution to all the problems in the world

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.

Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.

Processed foods contain chemical elements, which might confuse the appetite mechanism  (新陈代谢) that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism becomes inactive, and the result is weight gain and obesity.

The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.

To stop this vicious（恶性的）circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.
