材料一：去年3月以來,我國部分省市出現(xiàn)“腎結(jié)石寶寶”。9月12日，衛(wèi)生部認定，受三聚氰胺污染的嬰幼兒配方奶粉是導致嬰幼兒泌尿系統(tǒng)結(jié)石的元兇。為嚴肅處理嬰幼兒奶粉事件，國務院決定對事故原因和責任展開全面調(diào)查，10月9日公布實施《乳品質(zhì)量安全監(jiān)督管理條例》。

材料二：三鹿牌嬰幼兒奶粉事件是一起重大食品安全事件。對此，黨中央、國務院依法嚴厲查處三鹿奶粉重大食品安全事故相關(guān)責任人，維護人民群眾利益、確保食品健康安全。

（1）你從這次“毒奶粉事件”中可以看出市場調(diào)節(jié)具有什么樣的缺陷？試加以簡要說明。

請運用辯證唯物論的觀點說明：不同的人對國家采取的措施為什么有不同的認識? 應怎樣統(tǒng)一他們的認識?

27．（12分）2008年8月8日，中國人民乃至世界人民都不會忘記這個日子！中國成功地舉辦了奧運會，實現(xiàn)了中華民族的百年夢想。這帶動了一批高質(zhì)量的科技成果在比賽場館建設、節(jié)能減排、城市建設等方面的應用；高清晰的賽事轉(zhuǎn)播、絢麗夢幻的開幕式、復雜的賽事積分系統(tǒng)如同菲爾普斯在鳥巢奪下奧運8金的奇跡。北京奧運會每天都在上演驚奇，這既是一場體育盛會，也是一場科技盛宴。她讓全世界人民感受到了古老文明與現(xiàn)代科技的精密結(jié)合，推動“綠色奧運、科技奧運、人文奧運”理念的實現(xiàn)。

結(jié)合上述材料回答下列問題：

（1）從國家的角度說明國家重視科技創(chuàng)新的理由。

（2）運用國家職能的知識分析，在奧運會的舉辦過程中是如何展現(xiàn)中華民族豐富的文化底蘊的？

We have rather a small house, with only two bedrooms. You can imagine our alarm then, when Aunt Clara wrote to say that she was coming to stay with her family for the weekend. Her family, I should say, has four boys, all under the age of twelve.

I sent off a telegram(電報) at once, and explained in it that our house was too small. Aunt Clara called us up the next morning. ‘ I forgot to explain,’ she said in her sweetest voice, “the boys will be bringing a couple of tents .”

Even so my wife couldn’t make free from fear . It was true that we had a large garden, but there was still the problem of feeding four growing boys.

“And what if it rains ?”she asked. But Saturday morning turned out to be bright and clear when I went to the station to meet Aunt Clara. I tried to squeeze (塞) three of the boys, together with the luggage , into the back of the car. The youngest sat in front, with Aunt Clara and me.

“I didn’t see the tents among your luggage,’”I turned round and said to David, the eldest boy.

“The tents !”said Aunt Clara. “Oh！We left them in the luggage van(行李車廂).”

（）41. From the story, we know that the main problem was food .

（）42. Aunt Clara sent a telegram after she received the telegram.

（）43. The boys were going to sleep outside .

（）44. The man’s wife was looking forward to the visit.

“We needed furniture for our living room,”says John Kose, “but we didn’t have enough money to buy any.”So we decided to try making a few tables and chairs. John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Koses took a 2-week course（課程）for $ 280 at a night school. Now they make all their furniture and do repairs around the house.

Jim Hatfield has three boys and his wife has died . He has a full-time job at home as well as in a shoe-making factory. Last month, he received a car repair bill for $420. “I was very upset about it. Now I’ve finished a car repair course. I should be able to fix the car myself.

John and Jim are not unusual people. Most families in the country are doing everything they can to save money so that they can fight the high cost of living. If you want to become a “do-it-yourself”, you can go to DIY classes. And for those who don’t have time to take a course, there are books that tell you how to do things yourself.

46. We know from the passage that many people ________.

　A. seldom go to a department store to buy things

　D. he makes shoes in his home

49. Jim Hatfield decided to become a do-it-yourself when ______.

A. he had to raise the children all by himself

B. he could not possibly do two jobs

C. the car repair class was not helpful

D. his car repairs cost too much

50. What’s the best title of the passage?

A. Rose and Hatfield: Believers in DIY. B. You Can Do It ,Too.

C. The Joy of DIY. D. Welcome to our DIY Course.

　 (C)

Rivers are one of our most important natural resources(自然資源). Many of the world’s great cities are located on rivers, and almost every country has at least one river flowing through it that plays an important part in the lives of its people.

Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India , the Ganges is great. Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia, The greatest of all for navigation(航海), however, is the Amazon in Brail, It is so wide and so deep that large ships can go about two thousand miles upon it.

Besides transportation, rivers give food, water to drink, water for crops, and chances for fun and recreation for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam(大壩) across a river and let a lake form behind the dam. Then people can use the water not only to irrigate(灌溉) their fields but also to make electricity for their homes and industries.

However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits(利益) of this natural resource.

51.The greatest river for navigation is _________.

A. the Amazon B. the Nile

C. the Mekong D. the Mississippi

52.Which is Wrong?

A. The Nile is in India.

B. Almost every country has at least one important river.

C. Many cities are located on rivers.

D. Rivers play an important part in the lives of people.

53.By building a dam, people can use the water for______.

A. keeping the rivers clean B. only making electricity

C. washing clothes D. irrigation and making electricity

54.The water in the river is polluted because of _____.

A. people’s drinking water too much

B. people’s swimming in the river too much

C. chemicals and other materials

D. people’s building a dam across a river

55. The best title of the passage is _________.

A. Rivers in Cities B. The Importance of Rivers

C. Transportation D. Natural Resources

You can see Pizza Hut every few blocks, so it must be a very big business. Indeed it is .But believe it or not, it was started in 1958 by two college students with 600 dollars. The Carney brothers were trying to make some money so that they could use the money for their college education. They borrowed the money from their mother and sold pizza in a small house in their neighborhood. That’s how they got the name of the business. On the first day of their business, they gave away pizza to attract customers . Year after year, their business grew and now they often give free meals and chances to work to those in need.
