[单项选择] New ice core samples taken from the centre of the Greenland ice-sheet have given a detailed record of the last "interglacial (间冰期)" which rail from about 135,000 to 115,000 years ago. The cores, taken from a depth of 2,780 to 2,870 metres, show that during this period the climate oscillated(摆动) between three states instead of remaining in one, as in the whole of recorded human history. The middle state was like our own, but the others were either’’ much colder or warmer.
Worse, it seems that the climate flipped from one condition to another very rapidly. "It apparently took very little time, perhaps less than a decade or two, to shift between the states," Dr. J.C. W. White of the Institute of Arctic and Alpine Research at the University of Colorado wrote earlier this year in the scientific journal, Nature: "We humans have built a remarkable socio-economic system during perhaps the only time when it could be built, when the climate was stable enough to let us develop the agricul

第一篇
Eating Potatoes Gives Your Immune System a Boost
Eating potatoes is not only good for bowel health,but also for the whole immune system,especially
when they come in the form of a potato salad or eaten cold.In a study on an animal model,researchers in
Spain found that pigs fed large quantities of raw potato starch(RPS)not only had a healthier bowel,but also
decreased levels of white blood cells, such as leucocytes and lymphocytes(淋巴细胞)in their blood. White
blood cells are produced as a result of inflammation or disease,generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall
beneficial effect,a generally healthier body.The reduction in leucocyte levels was about 15 percent.Lower
lymphocyte levels are also indicative of reduce levels of inflammation,but the observed reduction in both
lymphocyte density and lymphocyte apoptosis is surprising.
In what was the longest study of its kind,pigs were fed RPS over 14 weeks to find out the effect of
starch on bowel health."The use of raw potato starch in this experiment is designed to simulate the effects of
a diet high in resistant starch,"said study leader Jose Francisco Perez at the Universitat Aut6noma de
Barcelona,Spain.
Humans do not eat raw potatoes,but they do eat a lot of foods that contain resistant starch,such as cold
boiled potatoes,legumes,grains,green bananas,pasta and cereals.About 10 percent of the starch eaten by
human is resistant starch一starch that is not digested in the small intestine and so is shunted into the large
intestine where it ferments.Starch consumption is thought to reduce the risk of large bowel cancer and may
also have an effect on irritable bowel syndrome(lBS).
Immunology expert Lena Ohman's team previously found that the overall lymphocyte levels do not vary
for lBS patients,but that lymphocytes are transferred from the peripheral blood to the gut,which supports
the hypothesis of lBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes
observed by the Spanish is therefore interesting,and a diet of resistant starch may be worth trying in IBS
patients.Ohman is currently at the Department of Internal Medicine,Goteborg University,Sweden.The
study is published in the journal Chemistry and Industry,the magazine of the SCI.
All of the following foods are rich in resistant starch EXCEPT_______.
A.pasta
B.grains
C.legumes
D.vegetables
