AOne sunny day, an ant went along the bank of a river. It felt very thirsty, so it bent down to drink from the river. But suddenly it slipped and fell into the water. The ant tried to swim back to the bank, but it couldn’t reach it. The current (水流) of the river was too strong.Just when the ant thought all hope was lost, a bird flew by, and saw the ant struggling in the water. Taking pity on the ant, the bird flew down, picked up a leaf, flew over the ant again, and dropped the leaf onto the water. The ant quickly climbed onto the leaf and was saved at last.A few days later, the ant came across the bird who had saved its life. It was resting on the branch of a tree. Suddenly, the ant saw a hunter aiming his gun at the bird. The ant quickly crawled towards the hunter and bit his foot. The hunter cried out in pain. On hearing the cry, the bird flew away. The brave ant saved the bird’s life.6. The ant went to the river to _____.A. play gamesB. drink waterC. have a bathD. have a swim7. What did the bird use to save the ant?A. A branch.B. A bank.C.

The ant saved the bird because it wanted to _____.A. stop the bird from flying awayB. thank the bird for saving its lifeC. thank the hunter for dropping his gunD. stop the hunter from aiming at the birdBHave you grasped the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style.Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it andconnecting it to things we are already aware of. In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures.For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message.Now scientists say there exist seven basic learning styles.·Linguistic: These people learn through listening, reading, speaking and writing.·Logical: These people learn with formula (公式) and principles (原理).·Visual: These people learn by seeing what they are studying.·Musical: These people learn well when information is presented through music.·Kinesthetic: These people learn from movement and physical activities.·Intrapersonal: These people learn best by linking new information directly with their own experiences.·Interpersonal: These people learn well by working with others.Therefore, if you know what learning style is your strength, you can balance your weakness, and get a more successful learning experience.10. From the passage, we know that our brains __________.A. deal with the information in different waysB. send out the information in the same wayC. organize information with our bodiesD. gather information in the same way11. A visual learner usually learns __________.A. through listening and speakingB. by seeing what he is learningC. from movement and physical activitiesD. by linking new information with his experience12. A musical learner will find it easy to learn __________.A. with formulas and principlesB. by working with othersC. through reading and writingD. through music he hears13. The purpose of the passage is to tell us to __________.A. learn more successfullyB. gather more informationC. understand more quicklyD. exchange information betterCZheng He was one of China’s most famous explorers. Towards the end of the fourteenth century, his fleet (舰队) sailed to countries far away.Zheng He had over 300 ships, some of which were over 150 meters long, and could carry up to 1,000 people. Besides, the ships carried gold, silver, silk, china and other treasures to give as gifts to the rulers of other countries. Some ships even had earth on board so that the sailors could grow their crops for food.On Zheng He’s first voyage, he set sail across the Indian Ocean. His fleet travelled many days far away from land. One day, they were hit by a storm. All the sailors thought the fleet was going to sink. Then a strange light appeared and after that, the storm passed. The strange light was probably electricity from the thunderstorm (雷雨), but the sailors in Zheng He’s fleet believed it was a sign of protection from the gods. With the belief, they were happy to follow Zheng He wherever he led them.Zheng He completed seven famous voyages between 1405 and 1433. He visited many countries in Asia and Africa. He brought back many gifts from the countries he visited, such as medicines, pearls (珍珠) and strange animals. The most famous of them were a giraffe and a zebra.In 28 years of travelling, Zheng He had managed to share the glory of China with many different countries. When he died in 1435, the stories of h is travels made him one of China’s most famous sailors.14. Some ships carried earth on board so that the sailors could __________.A. use it as a giftB. use it for exchangeC. plant trees for shadeD. grow their own crops for food15.
