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 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 (新陈代谢)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.What is the main purpose of this passage?

Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various species in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.
Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.
All domestic animals need proper food. It must be suitable for them, sufficient inquantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps(剩饭), and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.
Even well-cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price.

Looking back on my childhood. I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental maths.
Before World War I we spent our summer holidays in Hungary. I have only the dim memory of the house we lived in, of my room and my toys. Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into varied investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries. Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together .This has resulted in my publishing 300 papers and books. Which some may light honor, with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist? One of the outstanding and essential qualities required is self-discipline, a quality I lack. A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.According to the author, a born naturalist should first of all be _____

subways
| The Tokyo Metro and Toei Lines |
Features: The Tokyo Metro and Toei lines that make up of Tokyo’s huge subway system carry almost 8 million people each day, making it the busiest system in the world. The system is famous for its oshiya- literally, “pusher”- who push passengers into crowded subway cars so the doors can close. And you think your ride is hell. |

Features: The Moscow Metro has some of the most beautiful stations in the world. The best of them were built during the Stalinist era and feature chandeliers(枝行吊灯)，marble moldings and elaborate murals(精美壁画). With more than 7 million riders a day , keeping all that marble clean has got to be a burden. |
| The Hong Kong MTR |
Features: The Hong Kong MTR has the distinction of being one of the few subway systems in the world that actually turns a profit. It’s privately owned and uses real estate development along its tracks to increase income and ridership. It also introduced “Octopus cards” that allow people to not only pay their fares electronically, but buy stuff at convenience stores ,supermarkets, restaurants and even parking meters. It’s estimated that 95% of all adults in Hong Kong own an Octopus card. |
| Shanghai Metro |
Features: Shanghai is the third city in China to build a metro system, and it has become the country’s largest in the 12 years since it opened.

While only about 200 astronauts have had the excitement of looking down at Earth and commanding systems on the International Space Station, actually thousands of everyday middleschool students have experienced by Middle School Students, or EarthKAM, a camera system.
EarthKAM is an educational activity and outreach(扩展)investigation that also results in remote Earth sensing and observation. Using the Internet, the students control a special digital camera fixed aboard the space station, enabling them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest from the unique advantage point of space.
While EarthKAM offers a powerful way for students to investigate Earth from the unique perspective of space, it is also inspiring the next generation of flight controllers for space programs—involving university students to control and operate the camera system and related activities from the ground.
In the interview, Brion Au, one of the investigation developers at NASA's Johnson Space Centre, said，“EarthKAM is a payload(有效载荷)by students, for students. They are in charge. This system provides a viewpoint that the astronauts have...it's just aweinspiring！”So far, students have captured more than 40,000 photos of the Earth from the space station as it orbited the Earth once every 90 minutes, traveling at 17,500 miles an hour. The team at EarthKAM posts these photographs online for the public and participating classrooms around the world to view.
Au explains that this education investigation is inspiring students to explore the world by examining Earth, while promoting social studies, art, geography, science, technology, and math, among other important lessons involving research and teamwork. EarthKAM was started by Dr. Sally Ride, originally flying on the shuttles. The camera is located in the window Observational Research Facility, also known as the WORF, one of many the station's research facilities.How have thousands of students experienced similar excitement as astronauts?
| A．In the space station. | B．In the spaceship. |
| C．Using a camera system. | D．Teaming up with astronauts. |
What equipment should the students need for the research?
| A．Computer. | B．Recorder. | C．Telephone. | D．Radios. |
What doesn't belong to the next generation of flight controllers for space programs?
| A．University students' controlling the camera system. |
| B．University students' operating the camera system. |
| C．University students' related activities from the ground. |
| D．University students' investigating Earth from space. |
Who are responsible for EarthKAM?
| A．The astronauts. | B．The students. |
| C．The investigation developers. | D．The teachers. |
What's the main idea of the last paragraph?
