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 circle in its tracks, people need to consume food and supplements that will neutralize 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.It can be inferred from Para. 2 that __________.
| A．foods with natural enzymes help people keep fit |

I am wearing a small red ribbon this morning to remind myself and others around me that today is World AIDS Day.
The red ribbon, an international symbol of AIDS awareness, is gaining increasing public recognition as more Chinese, from top leaders to movie stars, wear it today.
Gone were the days when the topic of HIV/AIDS was a public and media taboo(禁忌). Over the past few years, we have watched, read and heard many stories from doctors, volunteers and public health officials at the forefront of HIV/AIDS prevention and treatment.
Quite a few people with HIV/AIDS have come forward to share their experiences on TV or in the media.
The local and central governments have become more forthcoming (be helpful) with their new prevention and treatment programmes, and financial input. The latter rose from less than 1 million yuan (US$ 121,000) in 1986 to a pledge of 800 million yuan (US$98.8 million) in the year of 2006.
The change from silence to public and media campaigns with official promises has been remarkable, especially since China battled through the SARS crisis.
But have we got a full grip on HIV/AIDS? What do we know about the extent of HIV/AIDS in China?
The figures, ranging from confirmed cases to estimates, remain debated. After all, no more than a year has passed since the policy of free medical tests was made public. Unknown numbers from the high-risk groups: drug addicts and people working in sex- related places as well as farmers who once sold blood could still be reluctant to come forward.
69. What does the red ribbon stand for?
A. AIDS B. World AIDS Day
C. AIDS awareness D. AIDS prevention and treatment
70. Which of the following is Not true according to the text?
A. The topic of HIV/AIDS was a public and media taboo in the past.
B. The topic of HIV/AIDS is now still a public and media taboo.
C. Now a lot of people with HIV/AIDS have come forward to share their experiences on TV.
D. The writer wears a small red ribbon because today is World AIDS Day.
71. In paragraph 5 “the latter” refers to ____________________.
A. financial input B. new prevention programmes
C. new treatment programmes D. the central governments
72. We can learn from the text that high-risk groups of HIV/AIDS in China include the following EXCEPT __________________.
A. drug addicts B. people working in sex-related place
C. farmer who once sold blood D. people getting close to those affected with HIV/AIDS
第二节：阅读下列短文，从每题所给的A、B、C和D四个选项中选出最佳选项。（共15小题，每小题2分，满分30分）
Have you noticed that the majority of human beings seem to focus on the negative? Bad news is often seen in the newspapers, television shows and magazines, but good news are often overlooked.
I saw a woman I was not very familiar with. She is a beautiful woman; every time I see her, I am struck by the smile on her face that can light up a whole room. So at one time I walked up to her and said, “You know, you are like liquid sunshine! Every time I see you, you give me so much joy.” I was not quite prepared for her reaction. She was blown away. Her eyes seemed about to shed tears, and she said, “That is so sweet! That is the nicest thing anyone has ever said to me!” It was as if nobody had ever told her how beautiful her appearance was. I was extremely moved by the moment I had shared with this woman.
Why not take notice of the positive and spread a little sunshine? When you are looking for beauty, you will begin to see it more and more. When you discover it, don’t be afraid to appreciate it. Not only will it make them feel good, it will make you feel good as well. I truly believe the saying, “What goes around comes around.” When you show kindness and sincerity, you will receive it back. You may even discover — much to your surprise — that you become the friend of someone you would never have expected to get along with.
66. The woman had tears in her eyes because __________.
A. the man’s behavior was so rude
B. she was nervous about the man’s words

In ancient China tea was probably used as a relish(开胃小菜) and as a medicine. Tea was first brewed(煮泡) as a medicine around 2,700 BC in the western mountains of China. Tea was likely seen as healthy in part because it was made with boiled water, which is safer to drink in an area of polluted water.
Tea drinking, and commercial cultivation(种植)，spread during the Tang Dynasty, 618-907, especially after a Buddhist monk(佛教僧侣), wrote a book on the virtues of tea, Cha Ching. Tea gradually became one of the seven basic necessities of Chinese life (The others are fuel, rice, oil, salt, soy sauce, and vinegar.)
A Japanese Buddhist priest, Saicho, is believed to have introduced tea to Japan, when he returned from a visit to China in 805. In Japan tea drinking was considered medicinal, and became closely associated with Zen Buddhism(禅宗).
Tea drinking also spread to Korea and Southeast Asia, and was taken over the Silk Road to Central Asia, Russia, and the Middle East.
Dutch explorers became familiar with tea in the 1590s and were soon importing tea to Europe. In 1657 the British East India Company held the first public sale of tea in England, while that same year Thomas Garraway began offering tea at his London coffee house.
In 1662 tea received a big boost(推进) in England when the Portuguese Catherine of Braganza, married King Charles II and introduced tea drinking to the British court.
Gradually, the British fell in love with tea, and with the sugar that went in it. In 1665, less than 88 tons of sugar was imported to Great Britain. By 1700, it had increased to 10,000 tons of sugar. In 1768 the East India Company imported 10 million pounds of tea to Britain.

Some fish form huge schools. Could fish set up schools and teach their children how to survive in the ocean? You may ask. No. Here the “schools” are not the places where you study. They are fish shoals (鱼群) that cover tens of kilometers. What causes hundreds of millions of fish to gather and move together is one of biology’s mysteries.
Darkness appears to be the first step to the creation of shoals, according to a study published in the March 27 journal Science. A team of researchers from the Massachusetts Institute of Technology (MIT) and five other institutions studied Atlantic herring (鲱鱼), which forms shoals on a fishing ground off Massachusetts. They used an underwater imaging technology and fish-finding sonar (声纳) to observe the herring over several days in autumn when they spawn (产卵).
They found that, as the sun set, fish in scattered (分散的) groups began swimming much closer to one another than they normally do. When the number of fish reached a certain point in an area, this set off a chain reaction of similar behavior that spread like a sound wave through the water.
The herring’s movement seemed to be started by sunset. The team didn’t record the breakup of these shoals, but a previous study suggested that as the sun rose, the shoals fell apart.
“When the light fades (逐渐消失), it’s safer for the fish to move away from the seabed,” says Nicholas Makris, a professor at MIT who led the research. “Once they have a certain number of other fish, they suddenly come together - forming a shoal covering tens of kilometers within tens of minutes.”
Herring form shoals to migrate during the autumn spawning season. Some shoals were 40 km across and 30 m from top to bottom. They formed in deep water and moved into more shallow waters to spawn.
Forming shoals helps protect them from predators (掠食者) by giving them simple strength in numbers. The ordered movement of the shoal means the fish can reach their spawning ground more quickly and more safely.
Scientists have never before gathered information on so many animals acting together. Understanding these herring shoals could lead to more ideas about what causes animals to move in schools, says Iain Couzin, a biologist at Princeton University, US.

I was parked in front of the mall wiping off my car. Coming my way from across the parking lot was what society would consider a bum (乞丐). “I hope he doesn’t ask me for any money,” I thought.
He didn’t. He came and sat on the curb (路边) in front of the bus stop but he didn’t look like he could have enough money to even ride the bus.
After a few minutes he spoke,“That’s a very pretty car.” He was ragged (衣衫褴褛的) but he had an air of dignity.
I said “Thanks” and continued wiping off my car. He sat there quietly as I worked. “Do you need any help?” I asked.
He answered in three simple but profound words that I shall never forget.
“Don’t we all?” he said.
I was feeling high and mighty, successful and important, above a bum in the street, until those three words hit me like a shotgun.
Don’t we all?
I needed help. Maybe not for bus fare or a place to sleep, but I needed help. I reached in my wallet and gave him not only enough for bus fare, but enough to get a warm meal and shelter for the day.
Maybe the man was just a homeless stranger wandering the streets. Maybe he was more than that. Maybe he was sent by a power that is great and wise, to minister to a soul too comfortable with himself.
Don’t we all? Those three little words still ring true. No matter how much you have, no matter how much you have accomplished, you need help too. And you never know when you may see someone that appears to have it all. They are waiting for you to give them what they don’t have.
