How could we tell time if there were no watches or clocks anywhere in the world?
The sun is probably the world’s first “clock”, except in the far north, where the Eskimos(愛斯基摩人) live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun as a clock. Even today, if you don’t have a clock, you can still know that when the sun shines, it’s day and when it’s dark, it’s night. The sun can also tell you if it’s morning, noon, or afternoon.
Some people live near the sea from the tides. In the daytime, for about six hours, water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours. Seamen on the ship learn how to tell time by looking at the moon and the stars. The whole sky is their clock.
In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.
A sand clock is an even better clock. If you had fine dry sand in a glass shaped like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom in exactly one hour. When the hourglass is turned over, the sand will take another hour to go back again
小題1: From the passage we can know there are _______ways to tell time besides the clock and watch.
A.3B.4C.5D.7
小題2:. The Eskimos in the far north can’t use the sun for a clock because________
A.they know very little about the sun
B.the sun there never goes down in winter
C.it’s too cold for them to go out to watch the sun
D.it has long dark winters and long light summers
小題3:. What does the underlined word “tides” mean in the passage?
A.洋流B.潮汐C.海嘯D.波浪
小題4: In which page of newspaper can you probably read this passage?
A.NewsB.ScienceC.AdvertisementD.Sports
小題5: What is the best title for the passage?
A.Different Ways to Tell TimeB.How the Clock Was Invented

When you do not use your arms or your legs for some time, they will become weak. When you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory (記憶 )  works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it.  When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his own fault (過錯).  But if he tells us that he has a poor memory, many of us think that his parents may be blamed (責(zé)備 ) , and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write but they have to remember things, they cannot write them down in a small notebook.  They have to remember days, names, songs and stories, so their memory is being exercised the whole time.
So if you want to have a good memory, learn from the people: practice remembering things in a way as other people do.
小題1: Someone can’t have a good memory if _     
A.his parents don't have a good memory
B.he can't read or write
C.he doesn’t use his memory
D.he doesn't use his arms or legs for some time
小題2: If you do not use your arms or legs for some time,                    _
A.they become weak and wont become strong until you use them again
B.they will become stronger
C.they become weak but they slowly become strong again
D.you cant use them any more
小題3: Which of the following is true?
A.Your memory works in the different way as your arms or legs.
B.Your memory, like your arms or legs, becomes weak if you do not give it enough chance
to practice.
C. Don't learn how to read or write if you want to have a better memory.
D.A good memory comes from less practice.
小題4: Few people know that it is only _     if a friend has a poor memory.
A.his grandmother's faultB.his parents fault

Tanzania Tarangire is a national Park which lies in Tanzania.The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country.I recently visited Tarangire to see what it was like.
One of the first sightings upon entering the park which I found was a huge group of elephants.Our guide told us that Tagrangire was probably the best place in Tanzania to find large group of elephants, and that their population in the park was around 2,500.We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch.
To the right of the elephant group, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years.Compared with this tree, the elephant just looked like dwarfs (much smaller plants or animals)! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees.
As we continued our drive through the park, we finally reached a watering hole.Our guide warned us that there were lions all around us.It took us all a while to find them, but there they were! Most of them are resting in the shade under bushes, but there was one that was drinking from the watering hole directly in front of us.We then noticed just to our right, there were a couple of fresh zebra bodies — it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the kill, as our guide had mentioned that the zebra bodies were fresh and the kill had happened within the last hour.
Our final big sighting was one that none of us were expecting to see, even our guide! We stopped at a place where there were quite a many cars, with a sleeping leopard(美洲豹)there! We took photos and watched its surprising body before returning to our hotel as it was getting late.
So, I hope you enjoyed my description of Tarangire, and add this amazing park to your very own Tanzania travel route.

What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射)light(光). We see color because most of the things reflect light. Something is red, because it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat.The darker the colour is, the less light is reflected, the more light is taken in. So dark-colored(深色的)clothes are warmer in the sun than light-colored(淺色的) clothes.
小題1:When something reflects light, we can_______.
A.see its colorB.see its heat  
C.not see its colorD.see nothing

Do you know that each child in school catches six to ten colds every year? Though there is no cure for colds, there are some suggestions for you to avoid getting a cold.
First, you can avoid catching a cold by practicing healthy habits. Begin by eating healthy foods. Eat lots of fruits and vegetables and drink milk and juice. Other healthy habits include getting plenty of sleep at night and lots of exercise.
Next, you should try to avoid contact with the viruses that cause colds. If you can, stay away from large crowds. When people cough(咳嗽) and sneeze(打噴嚏), the cold virus goes into the air. Do not share a drinking cup, fork, or spoon with someone else because that could spread the virus. Washing you hands is also a good way not to catch a cold. The cold virus may be on the things like telephones and money. Shaking another person’s hand could even spread the virus. By washing your hands, you can stop the virus from infecting(傳染).

Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the climate is changing.
The earth will perhaps be warmer by about 7 degrees centigrade. At the South Pole and the North Pole, the ice will melt (融化). The sea level (海平面) will rise by about 7meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the sunrays(紫外線). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid (酸) rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
小題1:Some scientists believe that          .               
A. the earth is growing warmer
B. we can find oil in our forests
C. we have to burn down the forests every year
小題2:Ice at the poles will          if the earth gets warmer.
A. cover cities like London and Tokyo
B. raise the sea level by 7 degrees

小題3:Acid rain          .
A. brings great changes in our climate
B. kills pests in lakes and forests
C. kills the fish in rivers and lakes
