FOOD SAFETY

A question that often troubles food companies is how to control problems like rats and insects without harming the food. Pest control experts say poisons should never be used where they may enter food. They say the first line of defense against pests is to clean the places where the food is handled or stored.

Floors, food preparation surfaces and tools can be disinfected with chemicals like chlorine, iodine or bromine. Food containers should be stored about half a meter off the ground and about half a meter away from any walls. Storage areas should be kept dry and clean.

Containers for raw materials such as rice, wheat, etc. should be kept closed and clean. Any foodstuff split during delivery or handling should be cleared up both inside and outside the building. Pests enter a building from the outside, so pay attention to outer walls. Small stones can be used to cover the ground and block the growth of plants and the grass should be kept short to deny pests a place to live.

Check that doors and windows are completely closed. Also any hole that might allow pests to enter a building should be filled. Rats can enter through a hole the size of a coin. A mouse can pass through a hole half that size.

Supervisors should make a list of pest control measures to be taken by employees. This will aid the efforts and also help prepare for any inspections. In most countries, there is a food and drug administration bureau, or some agency with a similar name, which enforces rules nationwide, responsible for rules about the use of pesticides, etc. However, businesses where food is stored, prepared or sold must also follow state and local health laws. Most of these governmental departments or bureaus have their websites with information about food safety policies and other issues. People can easily access the information.

on, having outgrown the available food supplies. Today, a century and a half later, there are still experts who forecast the same global disaster—unless urgent measures are taken to prevent it. By the end of the present century there may well be over five thousand million people living on this globe, an increase of over fifty percent on todays figure. In order to keep pace with this increase in mankind the farmers of the world will have to step up their production of food by at least two percent every year. Such a rate of increase has never been maintained in any country by conventional methods of agriculture, despite modern mechanization and the widespread use of fertilizers. There are no large worthwhile reserves of potential farmland remaining, and good fertile land is continually being changed into industrial use. Moreover, erosion of the soil takes a constant toll (损失). Intensive research, carried out over many years in all manners of climate conditions, has produced a revolutionary method of growing crops without using any soil at all. Hydroponics (水栽 法), as this technique is called, may well be the answer to all our food worries; already it has accomplished wonders in producing huge crops. Hydroponics was once a complicated and expensive business, now it is well out of the experimental stage. Labor costs are far lower than when normal methods of agriculture are employed. In fact, it is a completely automatic system. There is no hard manual work, no digging or ploughing, and no weeding to speak of. Yields can be far higher than they are in soil.

Which of the following best sums up the whole passage？

A．Malthus" prediction has been proved to be correct by modern experts.

B．Hydroponics is a new development in agriculture.

C．Hydroponics may be the answer to the world food shortage in the future.

D．Conventional methods of agriculture should be improved so as to step up food production by two percent every year.

A.make

B.reach

C.put

Questions 1 to 5 are based on the following passage.

Some of the world's most sign significant problems hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of some of the world's major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.

The authors take a vast number of data points for the four most important crops: rice, wheat, corn and soyabeans(大豆). They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in the 1990s and 2000s.

There are two worrying features of the slowdown. One is that it has been particularly sharp in the world's most populous(人口多的)countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency cannot be taken for granted if yields continue to slow down or reverse.

Second,yield growth has been lower in wheat and rice than in corn and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Corn and soyabeans are more important as feed grains. The authors note that "we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world."

The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.

Instead, it says, thanks to slowing population growth, land currently ploughed up for crops might be able to revert(回返)to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.
