2.When people think of improving their diet,they often talk about eating more fruits and vegetables.Others want to eat more fish and less red meat,in addition to reducing the amount of food they eat.But,they can improve their diets even more with just a simple addition.American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals.
Pennsylvania State University Associate Professor Shiela West led an investigation of the health effects of a spice-rich diet.Her team knew that a high-fat meal produces high levels of triglycerides(甘油三脂),a kind of fat,in the blood.She said,"If this happens too frequently,or if triglyceride levels are raised too much,your risk of heart disease is increased."
As part of the study,her team prepared meals on two separate days for six men between the ages of 30and 65.The men were overweight,but healthy.The researchers added about 30milliliters of spices to each serving of the test meal,which included chicken curry,Italian herb bread and a cinnamon(肉桂樹皮)biscuit.The meal for the control group was the same,but it did not include any spices.
During the experiment,the researchers removed blood from the men every 30minutes for three hours.They found that antioxidant activity(抗氧化活性) in the blood of the men who ate the spicy meal was 13percent higher than it was for the men who did not.In addition,insulin(胰島素) activity dropped by about 20percent in the men who ate the spicy food.
Shiela West says many scientists think that oxidative stress leads to heart disease.And what exactly is oxidative stress?Think of an apple that has been cut in half and set aside for half an hour or so.The cut side of the apple turns brown.That is a simple explanation of what happens when oxidative stress comes in contact with the inside and outside of our bodies.
Professor West says,"Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease."She adds that the level of spices used in the study provided the same amount of antioxidants found in 150milliliters of red wine or about 38grams of dark chocolate.

66.What does the author advise people to do in their diets?D
A.Eating large amount of food.
B.Eating less fruits and vegetables.
C.Eating more vegetables and fish.
D.Eating small amount of food with spices.
67.What is the function of spices according to the passage?C
A.To help people lose weight.
B.To cure chronic disease.
C.To reduce the risk of heart disease.
D.To cause oxidative stress.
68.What happened to the men who ate the spicy meal according to the experiment?A
A.The antioxidant activity in their blood became increased.
B.The insulin activity in their body became increased.
C.The level of triglyceride in their blood was increased.
D.The oxidative stress in their body was strengthened.
69.What does Professor West show by citing the example of a half apple?B
A.The whole thing can be divided into two parts.
B.It implies oxidative stress is harmful to our health.
C.An apple is the only food that contains antioxidants.
D.We can keep diseases away if we have an apple a day.

分析 本文主要寫了富含香料的飲食有助于減少吃高脂肪食物的有害影響,抗氧化劑,如香料,可能是重要的,減少氧化應(yīng)激,從而減少慢性疾病的風(fēng)險.

解答 66.D 推理判斷題.根據(jù)第一段最后一句American researchers have found that  a diet rich in spices can help reduce the harmful effects of eating high fat meals.富含香料的飲食有助于減少吃高脂肪食物的有害影響章最后一段Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease抗氧化劑,如香料,可能是重要的,減少氧化應(yīng)激,從而減少慢性疾病的風(fēng)險.可以推斷出作者認為吃少量有香料的食物.
67.C 推理判斷題.根據(jù)句子Shiela West says many scientists think that oxidative stress leads to heart disease.可知許多科學(xué)家認為氧化應(yīng)激導(dǎo)致心臟。鶕(jù)句子Antioxidants,like spices,may be important in reducing oxidative stress and thus reducing the risk of chronic disease抗氧化劑,如香料,可能是重要的,減少氧化應(yīng)激,從而減少慢性疾病的風(fēng)險.由此可以推斷出香料的作用可以降低心臟病的發(fā)生.所以答案選C.
68.A 細節(jié)理解題.根據(jù)句子They found that antioxidant activity(抗氧化活性) in the blood of the men who ate the spicy meal was 13percent higher than it was for the men who did not他們發(fā)現(xiàn)的抗氧化活性(抗氧化活性)在那些吃辣的食物的人的血液是百分之13高于沒有吃的人.所以答案選A.
69.B 細節(jié)理解題.根據(jù)West says many scientists think that oxidative stress leads to heart disease.what exactly is oxidative stress許多科學(xué)家認為氧化應(yīng)激導(dǎo)致心臟.到底什么是氧化應(yīng)激?為了證明什么是氧化應(yīng)激,舉了半個蘋果的例子,為了說明氧化應(yīng)激對我們健康有害.所以答案選B.

點評 閱讀理解題測試考生在閱讀基礎(chǔ)上的邏輯推理能力,要求考生根據(jù)文章所述事件的邏輯關(guān)系,對未說明的趨勢或結(jié)局作出合理的推斷;或根據(jù)作者所闡述的觀點理論,對文章未涉及的現(xiàn)象、事例給以解釋.考生首先要仔細閱讀短文,完整了解信息,準(zhǔn)確把握作者觀點.

After losing two grandparents within the past year,I have taken some time to reflect on(反思) what is most important.I want to let you know what a positive influence you have been on me.I am the person I am because of you.

But you taught me how to fix it.
I love and respect you.You are always patient,with a quiet determination.
Grandma,thank you for everything you have taught me.I hope that I am able to pass on all these memories and skills to my children and grandchildren.
Love always,
Kelly

11.I was at Kendriya Vidyalaya in Bambolim,Goa,in the 1980s.On Inspection Day one year,an officer and his team from the Board of Education were coming to see how our school was run.As usual,our teachers asked us to be prepared.
At the end of the day,Mrs Sushila Tyaji,our Hindi teacher,walked in and told us that the inspector had come and qu ietly observed the class from the back door.He had also left an adverse remark!That was sad for us.Would we now be punished for having failed our teachers?There were no answers from Mrs Tyaji.Instead,she wrote the Hindi word"dukh"on the blackboard.And then she did something I have never seen a teacher do in my entire school life.She apologized.
"I am sorry for having taught you something wrong,"she said."I missed out the dots between the letters‘du'and‘kh'.The inspector told me this in the staffroom.I hope you will not make this mistake in future."
That admission had a significant effect on me.If our teacher can say sorry to us when she is wrong,why can't I?The incident helped me get rid of two common vices-ego and dishonesty.
Twenty-three years passed.I had to let my teacher know what that lesson meant to me.I recently located Mrs Sushila Tyaji using the Internet and went to meet her with my husband.
    She smiled when she heard my story of how her small decades-old apology had transformed me for good."It's tough being a teacher.But every once in a while,when an old student comes along and tells us that we did something right,it makes up for everything else,"she said.
4.The underlined word"adverse"in Paragraph 2 can be replaced by"B".
A.offensive         
B.unfavorable       
C.encouraging        
D.unforgettable
5.At the end of Inspection Day,Mrs TyajiC.
