A

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant(香的) flavor was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria(自助) feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．

So, in selecting food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”, 　which humans soon lose．Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-established habits．Some people eat fox, dog and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．

Native to America, the cane toad(癞蛤蟆)was introduced to northern Queensland 70 years ago to control sugarcane beetles(甘蔗害虫)．The toads failed in that duty but spread across Queensland and into neighboring northern area.

Now it calmly invades(侵略)the states of Western Australia and New South Wales (NSW). NSW wildlife experts fear the amphibians--which have poisonous backs that kill hungry predators,(食肉动物)--will have a terrible effect on native animals.

Those fears may be about to be realized．Australia's leading government research body，　 the 　Commonwealth Science and Industry Research organization　 (CSIRO)，forecasts a rise in average temperatures that will make NSW ideal living place for the cane toad．

Tony Robinson，head of CSIRO’s Wildlife，Pests，and Diseases Program，said climate change is increasing the amount of suitable living place for the toad．

“With climate change，the cane toads might go down as far as Sydney and some areas of Westem Australia，”Robinson said．

Recent estimates put the pace of the toad’s westward march at nearly 1 7 miles(27 kilometers)a year and slightly slower from north to south．

More southerly cities，　 such as Melbourne and Adelaide，　 would likely remain too cold and dry to ever suit the toads，Robinson noted，but Perth could expect cane toads in five years’ time．

Sydney could see their arrival in the next 20 years．

Robinson said there is no 0ne method that will keep the toads under control．

The cane toads already cover at least half of Queensland and most of the northern country the toads are believed to number in the billions.

A Venezuelan virus was tried in the 1990s but had to be given up after it was found to also kill native frog species.

Scientists and governmental bodies believe a national approach is needed.

The main threat the toads cause to species such as dingos, quolls, goannas, and crocodiles is the poison contained in glands (腺) on each of the frogs' shoulders. The poison sprays out when the toads are threatened or handled roughly.

The poison is made up of 14 different chemicals. Together they cause rapid heartbeats, excessive salivation, convulsions, and paralysis.

Cane toads also compete, and usually win, the hunt for food and living space.

“If the government and other states combine resources, I believe we can achieve a very practical biological -control research program, ”Burns said.

Zurich of Switzerland is the city with the highest quality of life in 2006, while Baghdad, for the third year running, has the lowest, a survey published by human resource company Mercer on Monday shows. Zurich, Geneva and Vancouver made the top three in the list while Bangui in the Central African Republic and Brazzaville, the capital of Congo Republic, joined Baghdad in the bottom three.

Almost half the top 30 scoring cities are in Western Europe. In this region, Vienna follows Zurich and Geneva in　 4^th position． other highly-rated cities include Dusseldorf Frankfurt and Munich in positions 6，7 and 8 respectively．Athens remains the lowest scoring city in Westem Europe，standing at position 79．

Chicago is one of the biggest climbers in．the rankings since 2005，rising to 41^st　 from　 52^nd due to reduced crime rates，while Cairo is one of the biggest fallers，sliding nine places to　 131^st　 out of 215 cities．“(This was)due to political turmoil and terrorist attacks in the city and surrounding area，”Mercer said．

Asia-Pacific Auckland and Wellington have both moved up the rankings from 8^th to 5^th and 14^th to 12^th places respectively，while Sydney remains at position 9．In Asia，Singapore ranks　 34^th followed by Tokyo，Japan’s highest scoring city，at position 35．Hong Kong’s modem and efficient infrastructure，including its airport which is considered one of the best in the word, has pushed it up from 70^th to 68^th position. The top-ranking city in China’s mainland is Shanghai in 103^th place．

“Beijing and Shanghai are on the rise and should experience rapid improvements in quality of living in the coming years. This is mainly due to greater international investment driven by lower cost of labour and manufacturing expertise,” explained Mr. Slagin Parakatil, Senior Researcher at Mercer.
