Question

14．Rice is an important part of many people's diets．Researchers from the Harvard School of Public Health in Massachusetts have released a report about rice．It shows that eating white rice increases the risk of Type Two diabetes （糖尿�。�．However，eating brown rice reduces the risk of the disease．
The World Health Organization says more than two hundred and twenty million people worldwide have diabetes．Type Two diabetes results when the body cannot effectively use the sugar it produces．
    More than thirty-nine thousand men and one hundred and fifty-seven thousand women took part in the study．They were asked about their diet and day-to-day activities，as well as any pre-existing diseases．The study found that the people who ate five or more servings of white rice per week had a seventeen percent increased risk of developing Type Two diabetes．But those who ate two or more servings of brown rice a week had an eleven percent reduced risk of getting the disease．
   Brown rice is the grain in its natural form．White rice results after it has been refined．This involves removing the outer cover．Only the inner white kernel is left．White rice is often enriched to replace some nutrients lost during the refining process．
   Qi Sun is the lead writer of the report．He says the outer parts of brown rice slow down the work of the body's digestive enzymes （消化酶） into starch．This means that the release of sugar into the bloodstream is slower after eating brown rice compared to white rice．
   A diet of foods that quickly release sugar into the bloodstream has been linked with a greater risk of Type Two diabetes．The exact reason for this is not known．
   Doctor Sun says less refined grains have more nutritional value than refined grains．He says replacing white rice with whole grains like whole wheat or barley could result in a thirty-six percent lower chance of developing Type Two diabetes．He says people should replace white rice and other refined carbohydrates with whole grains whenever possible．
   However，brown rice does not last as long as white rice because of the oil-rich layer of bran．This makes it less usable in poor communities．The International Rice Research Institute is working to develop kinds of white rice whose starch is released more slowly．
63．What is the exact reason of Type Two diabetes？D
A．Eating too much white rice
B．Sugar in the bloodstream．
C．digestive enzymes in the starch
D．It is still unknown to us．
64．What does the underlined word"refined"in the fourth paragraph mean？A
A．Processed
B．Cut
C．Struck
D．Developed．
65．Which of the following is true？C
A．White rice has more nutritional value than whole grains．
B．The oil-rich layer of bran can prevent the brown rice from going bad．
C．Eating brown rice may reduce the risk of developing Type Two diabetes．
D．The outer cover of brown rice will speed the release of sugar into the bloodstream．
66．What's the best title of the passage？C
A．The importance of rice                       
B．Brown rice and white rice       
C．Diabetes and rice eating                     
D．Sugar and diabetes．

Answer 1

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了米飯是許多人的飲食的重要組成部分，吃白米飯增加糖尿病的風險，吃糙米減少疾病的風險．

解答 63．D  細節(jié)理解題．根據(jù)文章第六段"A diet of foods that quickly release sugar into the bloodstream has been linked with a greater risk of Type Two diabetes．The exact reason for this is not known"可知二型糖尿病的確切原因我們不清楚；故選D．
64．A  詞義猜測題．根據(jù)文章第四段"Brown rice is the grain in its natural form．White rice results after it has been refined．This involves removing the outer cover．Only the inner white kernel is left"Brown rice是自然形態(tài)的谷粒，精米經過精煉后會得到結果，這就包括去除外蓋，只剩下內部白粒；可知詞義是精煉，處理的意思；故選A．
65．C  細節(jié)理解題．根據(jù)文章倒數(shù)第二段"He says replacing white rice with whole grains like whole wheat or barley could result in a thirty-six percent lower chance of developing Type Two diabetes"可知吃糙米可能降低患二型糖尿病的風險；故選C．
66．C 主旨大意題．通讀全文，可知文章主要講了米飯是許多人的飲食的重要組成部分，吃白米飯增加糖尿病的風險，吃糙米減少疾病的風險；可知最佳標題為米飯與糖尿��；故選C．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
