2、sour milk.The other three groups are the meat and fish group,the fruit and vegetable group,and the bread and rice group.Each meal should have at least one food from all four main groups.With all these food together,you will be given enough energy during the day.It is easy to get into bad eating-habi
3、ts.You may eat your breakfast in a hurry to get to school on time.Or you may not have time for a good lunch.It may seem easy to.But you will find yourself tired in these days and you can not think quickly.Watching what you eat will help your body remain healthy and strong.It is also good to take som

8、ce has made big steps in making food more fit to eat,it has,at the same time,made many foods unfit to eat.Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well.That food is related to illness is not a new discov
9、ery.In 1945,some researchers realized that things commonly used to keep colours in meats and other food additives caused cancer.Yet,these additives remain in our food,and it is difficult to know which things on the wrappings of foods are helpful or harmful.The additives which we eat are not all so d
10、irect.Farmers often give penicillin to their animals,and because of this,penicillin has been found in the milk of cows.Sometimes similar things are supplied to animals not for their health,but just to make a profit.The farmers are simply trying to fatten the animals in order to get a higher price on
11、 the market.Although some countries have tried to control such things,the practice continues.6.According to this passage,we can know .A.perhaps most of human illness is caused by what we eatB.perhaps most kinds of cancer are related to what people eatC.cancer was discovered in 1945D.science has made

15、hai Water Authority.With the city's population expected to increase only slightly and the economy to boom by 2020,Chen Yin,an official with the water authority,said Shanghai's water consumption will not increase from its present amount.Zhang Yue,director of the Urban construction Division un
16、der the Ministry of Construction,said,”Shanghai is the first city in the country to publicize these ambitions.They will not be easy to achieve.”He said water saving will help keep the sustainable development of China's economy.Saving one cubic meter of water means saving the city's infrastru
17、cture(基础设施)costs by 10 000 yuan.Last year,Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.“The aim is to arouse public awareness of the seriousness of water shortages,”Chen said.”The abundant surface water and amou
18、nt of rain of the city are so misleading that they result in improper use of water.”Shanghai lacks drinkable water.The Huangpu River,which supplies 80 percent of the city's drinkable water,is nearing exhaustion.The city,therefore,has been exploring new sources from the Yangtze River and growing
19、forests along it to conserve quality water.Besides penning regulations,the authority is popularizing technology among the public to efficiently cut the amount of water used.At present,the city has 600 000 family toilets,each using 13 liters of water per flush.These are to be renovated(整修)to use only
20、 9 liters of water per flush.The authority is renovating the first 200 toilets for householdsat a cost of 40 yuan each.In three years,all the toilets will be renovated,which saves the city nearly 15 million yuan every year in water conservation.Another task the city is engaged in is the treatment of
21、 sewage(污水)to improve the water environment.At present the city can only treat 44 percent of its daily 5.04 million tons of waste water.To meet the total demand,27 more sewage treatment factories are to be established with an estimated investment of 18 billion yuan.11.The people in Shanghai get thei
22、r daily water mainly from now.A.undergroundB.the Yellow RiverC.the Yangtze RiverD.the Huangpu River12.The underlined words “the aim” here refer to .A.the quality of drinking water in Shanghai will meet European Union standard by 2010B.citizens in Shanghai will drink the best water in the world by 20
23、20C.water saving will help keep the sustainable development of China's economyD.saving one cubic meter of water means saving the city's infrastructure costs by 10 000 yuan13.The authority is renovating the first 200 toilets for households to .A.make people's living more convenientB.save
24、drinkable fresh waterC.ease employment pressureD.meet the total demand of water14.The writer wrote the passage to .A.call on residents to save water in their daily lifeB.seek(寻找)ways to solve water shortage existing in ShanghaiC.introduce Shanghai's advanced experience in improving the water env
25、ironmentD.show that citizens in Shanghai will have the best drinking water in the world15.In the opinion of Zhang Yue,the real meaning of the action to publicize these ambitions is to make people know .A.it is not easy to achieveB.water shortage is very serious in ChinaC.the importance of improving
26、infrastructureD.economic development can't be separated with water supplyDDid you ever look up at the moon and think you saw a man's face there?When the moon is round and full,the shadows of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth an
27、d eyes. At least,some people think so. If there were a man on the mooninstead of mountains and valleys that just look like the face of a manwhat would he be like?He would not be like anyone you know. He would not be like anyone anybody knows. If the man on the moon were bothered by too much heat or
28、cold the way Earth people are,he could not stay on the moon. The moon becomes very,very hot. It becomes as hot as boiling water. And the moon becomes very,very cold. It becomes colder than ice.Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark.If the
29、 man on the moon had to breathe to stay alive,he couldn't live on the moon because there's no air there. (He'd have to carry an oxygen tank,as astronauts do. )There's no food on the moon,either. Nothing growsnot even weeds. If the man on the moon liked to climb mountains,he would be
30、very happy. There are many high places there,such as the raised land around the holes,or craters,of the moon. Some of these rims are as tall as Earth's highest mountains. But if the man on the moon liked to swim,he would be unhappy. There is no water on the moonjust dust and rock. When you think
31、 of what it's like on the moon,you may wonder why it interests our scientists. One reason is that the moon is Earth's nearest neighborit is the easiest place in space to get to. Going back and forth between the moon and Earth,astronauts will get a lot of practice in space travel. Things lear
32、ned on moon trips will be of great help to astronauts who later take long,long trips to some of the planets. Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on th
33、e moon would give them a clearer,closer view of the stars. 16.Which of the following is the best title of the passage?A.The Moon. B.The Man on the Moon. C.Research on the Moon. D.What It Is Like on the Moon. 17.What is the reason why our scientists are interested in the moon?A.The moon is beautiful.

35、he moon is quite different from that on the Earth. B.Traveling between the moon and Earth will do much good to astronauts. C.There is some food and weeds on the moon,even though there's no air. D.If you want to drink hot water on the moon,it's not so hard to boil water. 19.The underlined wor
36、d “rims” in Paragraph 8 means. A.ballB.hillC.round edgeD.height20.What is the main thought of the passage?A.We can learn much from research on the moon. B.There may be human beings on the moonC.If there were a man on the moon,there would be many similarities between the man on the moon and on the Ea
37、rth. D.A telescope on the moon would help scientists have a clearer,closer sight of the stars. EThe vitamins are named by letters of the alphabet (字母表). Vitamin A is needed by the eyes. There is Vitamin A in milk,butter,and green vegetables. It can be kept by the body. Vitamin B cannot be kept. It m
38、ust be supplied all the time by some of the food we eat. Vitamin C is very important to the body. Without it men's teeth become loose (松的) and their arms and legs get weak. Lemons,oranges and tomatoes have Vitamin C in them. Vitamin D is the sun vitamin. We get it in milk and eggs and from sunli
39、ght on our skin. There are other vitamins,but these A,B,C and D are the most important.21.What is the main idea of the passage?A.The importance of vitamins. B.How to get vitamins. C.How to go on a diet. D.The order of the alphabet. 22.If somebody's eyes are in poor condition,probably he needs. A

FOne night when my wife was preparing dinner,our little son took a piece of paper to her,which read:For washing the car $5.00For making my own bed t
42、his week $1.00Going to the provision shop $0.5Playing with little sister $0.25Taking out the rubbish $1.00Getting a good report card $5.00And for sweeping the common corridor $2.00Total $14.75His mother looked at him standing there expecting payment. I could see a thousand memories flashed through h
43、er mind. So she picked up the pen and turning the paper over,this is what she wrote:For 9 months I carried you,growing inside me No ChargeFor the nights I sat up with you,doctored and prayed for you No ChargeFor the toys,food and clothes and wiping your nose No ChargeWhen you add it all up,the full
44、cost of my love No ChargeWell,when he finished reading,he had great big tears in his eyes. He looked at his mother and said,“Mummy,I love you. ”Then he took the pen and in great big letters wrote on the “bill”“All paid”. 25.What's the best title for this passage?A.Part-time JobB.Mother's Lov

47、idD.the mother was angry with what the boy saidGComputers have many uses today:Computers can solve difficult problems and control other machines. Many people use small computers called calculators(计算器) to solve simple math problems quickly. Scientists use large computers to solve many problems at th
48、e same time. You can play games with computers,and some computers can help you learn languages. The Kurzweil Reading Machine is a special kind of computer. It can read books for blind people. To use the Kurzweil machine,a blind person can simply open the book and put it down on the scanner(扫描仪). The
49、 machine “reads” the words on the page. When one page is finished,the blind person turns the page and puts the book on the scanner again. The Kurzweil machine can read in a normal voice or in a special fast voice. It can read words with small letters and large letters. Blind people like the Kurzweil
50、 machine because they can “read” anything with it:newspapers,magazines,books,even typed letters. Many libraries now have Kurzweil machine for blind people to use. The Kurzweil machine can also help shortsighted children learn to read. 29.What does the first paragraph mainly tell us?A.Uses of compute
51、rs.B.Calculators. C.Computer languages.D.The Kurzweil Reading Machine. 30.Which of the following is TRUE?A.Computers can solve all the problems people can't. B.Large computers can only solve one problem at one time. C.When using the Kurzweil machine,a blind man needn't do anything. D.The Kur
52、zweil machine can help not only the blind but also the shortsighted children. HA young man named Charles Lyell had different ideas. He wrote a book about them called Principles of Geology (地质学). The earth,according to Lyell,was not only thousands of years old,it was millions of years old.As to (关于)
53、the common belief that changes in the earths surface happen suddenly because of a single earthquake or flood,he said that this might happen once in a while,but usually these changes took place very slowly. He believed that the surface of the earth had been changing from the beginning of time. The ch
54、anges,he said,were caused by the long-term action of the winds and seas,and by forces such as volcanoes breaking out under the earths surface. Once in a great while he thought,a mountain might appear for the first time after an earthquake. But usually mountains would rise slowly and steadily. Profes
55、sor Henslow was interested in Lyells ideas,but he did not actually believe them. Charles Darwin could not make up his mind about them. But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world.At Cambridge,Charles Darwin studied just enough to
56、 pass the examination,and received his college degree in 1831.During this time,he had become more and more interested in geology. At the end of the school year,he went to North Wales with one of his teachers to examine the rock formations (构成) and to search for fossils (化石). Fossils are the remains
57、of ancient living things. They are usually found fixed in rocks in the earths crust (地壳). Fossils may be of animals,such as fish,insects,birds,or humans. They may be of plants from tiny leaves to huge trees. When a living creature dies,it usually decays (腐烂)or is eaten by animals. However,if it sinks into a riverbed (河床) or is quickly covered by the blowing sands of a desert storm,the bones are kept up in the earth. Over many years the soft inner parts of a bone dis
