The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

BEIJING (AP) — Sandstorms whipping across China shrouded(遮蔽) cities in an unhealthy cloud of sand Monday, with winds carrying the pollution outside the mainland as far as Hong Kong and Taiwan.
It was the latest sign of the effects of desertification: Overgrazing, deforestation, urban sprawl(无计划地扩展) and drought have expanded deserts in the country's north and west. The shifting sands have gradually moved onto populated areas and worsened sandstorms that strike cities, particularly in the spring.
Winds blowing from the northwest have been sweeping sand across the country since Saturday, affecting Xinjiang in the far west all the way to Beijing in the country's east. The sand and dust were carried to parts of southern China and even to cities in Taiwan, 1600 miles (2600 kilometers) away from Inner Mongolia where much of the pollution originated.
The sandstorm in Taiwan, an island 100 miles (160 kilometers) away from the mainland, forced people to cover their faces to avoid breathing in the grit(砂砾) that can cause chest discomfort and respiratory problems even in healthy people. Drivers complained their cars were covered in a layer of black soot in just 10 minutes.
In Hong Kong, environmental protection officials said pollution levels were climbing as the sandstorm moved south. Twenty elderly people sought medical assistance for shortness of breath, Hong Kong's radio RTHK reported.
The latest sandstorm was expected to hit South Korea on Tuesday, said Kim Seung-bum of the Korea Meteorological Administration. The sandstorm that raked(掠过) across China over the weekend caused the worst "yellow dust" haze in South Korea since 2005, and authorities issued a rare nationwide dust advisory.
Grit from Chinese sandstorms has been found to travel as far as the western United States.
China's Central Meteorological Station urged people to close doors and windows, and cover their faces with masks or scarves when going outside. Sensitive electronic and mechanical equipment should be sealed off, the station said in a warning posted Monday on its Web site.
State television's noon newscast showed the tourist city of Hangzhou on the eastern coast, where graceful bridges and waterside pagodas were hidden in a mix of sand and other pollution. In Beijing, residents and tourists with faces covered scurried along sidewalks to minimize exposure to the pollution.
A massive sandstorm hit Beijing in 2006, when winds dumped about 300,000 tons of sand on the capital.We can learn from the text that .
| A．the sandstorms were purposely made by China. |
| B．the writer thinks that China government should be responsible for the pollution. |
| C．the sandstorms badly affected the air in US. |
| D．China's Central Meteorological Station will be closed. |
The passage tells us that the sandstorms mainly came from .
| A．Xinjiang | B．Hangzhou | C．Beijing | D．Inner Mongolia |
The underlined word, “respiratory” (in Para.4) means .
| A．breathing | B．digesting | C．hearing | D．walking |
Which of the following statements is NOT true?
| A．South Korea seldom issues nationwide dust advisories. |
| B．Taiwan is 1,600 miles from Beijing. |
| C．Sandstorms have hit Beijing more than once. |
| D．In Hong Kong some old people need help for shortness of breath caused by sandstorms. |
