Competition is great for kids, but it does have its dark side. 71 When this happens it takes the fun out of the activities they participate in. Kids need to keep a healthy attitude toward competitive activities and as parents it is our responsibility to let them know that it"s not all about winning. 72
Kids under the age of ten usually lose interest if an activity is too competitive. A good idea for kids in this age group is to allow them to participate in competitive activities but without keeping score. Emphasize that the importance of the activity I to make new friends, have fun and learn about sportsmanship. 73
When kids enter middle school, competitive activities take on new meaning. Kids like to be recognized for their efforts and winning places them in the spotlight. 74. The unfortunate thing is that kids who lose constantly get discouraged and quit participating. They feel they can"t accomplish their goals or meet the expectations of teachers and parents. This can lead to low self-esteem and discourage kids from trying their best. It"s best to keep them participating in competitive activities even if they only do so in the backyard with a group of their friends.
As a parent, never put the emphasis on winning. 75. Give kids praise for doing their best whether they win or lose. This sends a positive message about putting forth their best effort.
A．Winning becomes more appealing.
B．Encourage young kids to win when he participates in a competition.
C．Getting angry or depressed when he loses.
D．The importance of participating in competitive activities is to have fun.
E．Some children become over-competitive and focus only on recognition and winning.
F．Rather, encourage kids to always give their best effort.
G．Encourage young kids to give their best effort and gain self-confidence. |

I am always eager to do experiments, especially chemistry ones. It"s 21 to work with test tubes and beakers , even though sometimes my efforts end in failure. Experiments were fun for me 22 a recent accident.
The accident happened when I was heating a big test tube with an alcohol burner , chatting to my partner. All of a sudden, the tube cracked. Even though I jumped from my seat when I heard the crack, the hair on my forehead was burnt as I was leaning too close to the test tube.
23 I had no time to be sad about my hair: the liquid in the test tube poured onto the table and caught fire. I"d never 24 anything so bad! My mind went blank for a moment. Then I quickly covered the fire with a damp cloth to put it out.
The teacher told me that the test tube broke in half at the bottom because we didn"t dry it properly before 25 it.
We calmed down and did the experiment, again. But our hearts were still 26 rapidly even after we walked out of the lab.
But my bad luck didn"t end there! Since all our 27 was focused on the flames while we were in the lab, I didn"t see the liquid falling onto my trousers.
During the following class, I felt a pain in my leg. Soon it became more and m6re painful and I touched the area with my fingers, 28 to make things better. But to my great 29 , the material of my trousers turned into powder! "Vitriol ! ! ! The terrible word came into my mind. I rushed out right away to wash and examine my poor skin. 30 , it was not a serious injury.
After changing my trousers I thought it"s very important to have a serious attitude in chemistry class. Doing scientific experiments as a learner is no laughing matter.

The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing down on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.
The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！
What you need
•A hard-boiled egg without the shell
•A bottle with a neck slightly smaller than the egg
•A piece of paper
•A match
Method
1） Check that the egg will sit firmly on the neck of the bottle.
2） Tear the paper into strips and put the strips into the bottle.
3） Light the paper by dropping a burning match into the bottle.
4） Quickly sit the egg on the neck of the bottle.
Result
Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.
Why it happened
As the paper burns, it needs oxygen and uses up the oxygen （air） in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it.
小题1:Why is there the need to take care when you are doing the experiment? | A．The bottle could break. | | B．You need to light the paper with a match. | | C．The egg needs to be shelled. | | D．The egg has to be perfectly placed on the neck of the bottle. |
小题2:In the experiment, the burning inside the bottle can___. | A．equalize the air pressure inside and outside | | B．make a seal in the neck of the bottle | | C．finish up the oxygen inside the bottle | | D．produce more oxygen inside the bottle |
小题3:How did the egg put into the bottle？| A．The oxygen inside the bottle sucked the egg in. | | B．It became saft without the shell. | | C．The neck of the bottle was wide enough. | | D．The outside air pressure forced it into the bottle. |
小题4:The experiment is carried cut to prove ______. | A．water pushes on your body when you swim underwater. | | B．the earth is surrounded by a layer of air called the atmosphere. | | C．the pressure of air around us has a powerful force. | | D．the air pressure is not equalized around us. |

New archaeological discovers suggest that trade between Europe and Asia along the Silk
Road probably began in some form many countries earlier than once thought. The findings, coupled with a widening range of scientific and historical research, could add a fascinating new
page to the epic of the Silk Road.
The latest and most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.
The official origin of East-West commerce along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission（使命）across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of Rome.
But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.
小题1:The word “coupled” in the first paragraph could best be replaced by ______. | A．produced | B．contributed | C．doubled | D．combined |
小题2:The silk thread found in the hair of an Egyptian mummy suggests that ______. | A．Egyptians had probably travelled to China to buy silk | | B．trade along the Silk Road began earlier than once thought | | C．historical research often achieves fascinating results | | D．new light can now be thrown on ancient trading practices |
小题3: Until recently most historians believed that trade along the Silk Road _______. | A．originated in the 2nd century BC | | B．extended human migration into eastern Asia | | C．began a million years ago | | D．primarily benefited the Egyptians |
小题4:Historians have always considered Zhang Qian’s mission important because they believe ______. | A．be brought back knowledge of Rome to the emperor | B．be discovered the Silk Road | | C．be helped establish East-West trade | D．be travelled as far as Afghanistan |

Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience.
Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland sheds light on where ice sheets melted during the ice age.
It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern areas. This surprised the researchers from the University of Bern.
Scientists have long assumed(认为) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by theAntarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea, the ice can easily just slip to the ocean instead of building up.
The researchers used a computer model to look at the ways the ice could melt and how it might affect sea levels. They compared these results to evidence(迹象) of how temperatures and currents actually changed during that time.
The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too.
The only reasonable conclusion, the scientists could make, was that the ice melted equally in the North and the South.
It is still a mystery(谜) as to what caused the temperature changes that caused the ice to melt.
72. We can learn from the text that _____.
A.we have experienced temperature cycles since they began
B.what caused ice to melt is still unknown
C. the planet was much colder than it is now between 65,000 and 35,000 years ago, during which time temperature hardly changed
D. before the new study, scientists long believed that ice melted just in either northern or southern areas
73. The underlined phrase "sheds light on" （in Paragraph 3） can be replaced by _____.
A. throws doubts on B. beats down on C. makes it clear D. makes light of
74. The first two paragraphs were written _____.
A. to lead up to the subject that ice melted during the 30,000-year-long ice age
B. to describe what the weather was like during the ice age
C. to compare climate nowadays with that of the ice age
D. to explain what a temperature cycle is
75. Which of the following best shows the relationship between ice, ocean currents and temperatures according to the text?
A. Ice can easily slip into the ocean.
B. Temperature and currents changed as a result of ice melting.
C. Temperature changes lead to ice melting or water freezing, which in turn has an effect on ocean currents and temperature.
D. Ice melted and then froze again due to temperature. |
Think of London and you’re likely to think of the city’s famous bright red double-decker(双层) buses．Think of Thailand’s capital city, Bangkok，and the noisy tuk-tuk(三轮摩托车) may come to mind．Picture the American city of San Francisco and you might see the city’s cable cars(电车)．
Imagining what these cities would look like without their red buses，tuk-tuks or cable cars is difficult．They are symbols of these cities that make them different from anywhere else in the world．However,these city symbols，which are so 1oved by tourists，are not always so well loved by their city 1eaders． City 1eaders want what is best for their city, which often means the most modern transport．
In Thailand，Bangkok city authorities have forbidden new tuk-tuks because they consider them noisy and polluting．However, the ban has largely been unsuccessful，as it has not changed Thai people’s preference for the inexpensive tuk-tuks over taxis．
In London，the city’s first ever mayor got rid of the red double-decker buses． which he thought were old—fashioned, by selling them to other countries．His plan worked．but Londoners were upset to lose the charming old buses that they believed represented the best of their city. They made their upset felt， when the mayor came up for re-election 1ast year．Most Londoners voted for his competitor, who promised to bring the bus back．Now, an improved version(版本)of the double-decker bus will hit London’s streets in 2012．
AS for San Francisco, several cable cars remain in use but mainly as tourist attractions．They are too slow to be used for anything other than scenic trips．
City transport symbols may have palace in their city people’s hearts，but it seems they are increasingly out of step with the modern world．As Londoners have proved，their continued 1ife depends on people’s willingness to fight for their survival．
5．What’s the purpose of writing the first paragraph?
A．To show the cultural significance of several cities’unique transport systems．
B．To introduce some old-fashioned means of transport, which are symbols of three tourist cities．
C．To use the old transport symbols to attract more tourists to visit the cities．
D．To explain why those cities are popular with tourists around the world．
6．Bangkok’s ban on tuk-tuks is unsuccessful due to ________.
A．people’s unawareness of environmental protection
B．tourists’preference for tuk-tuks over taxis
C. the lack of severe punishment for violation
D．1ocals’willingness to take the tuk-tuks
7．The London double Decker bus is returning mainly because______.
A．it is an improved version B．The new mayor also loves it
C. it is popular with tourists D．Londoners fought for it
8．Which example can prove old city transport symbols are not loved by city leaders?
A．Bangkok city authorities tried to get rid of the cheap tuk-tuks．
B．The mayor who sold double-decker buses lost the re-election．
C．The new mayor will bring back improved double-decker buses．
D．Only a few cable cars remain in use by tourists in San Francisco．
9．We can conclude from reading the passage that_______.
A．Tourist cities will lose their charm if their old transport symbols disappear
B．A modern city should get rid of inefficient old transport
C．Old city transport symbols now face the problem of survival
D．The writer is in favor of keeping the old city transport symbols |
