My son was in the 4th grade last year, and he had a teacher called Miss Green. I believe that when he is an adult he will surely look back on her as the best teacher he has ever had.My son has attention deficit disorder(注意力缺损症) that makes it a little more difficult for him to learn. She was able to change her teaching methods for him so that he could keep up with the rest of the class. As a result, he got straight As on many subjects. She regarded her class as a family and they even had their own class song. She would often have them sing it to encourage them and develop a team spirit for them. When she saw that they were no longer listening carefully to what she was teaching, she would have them close their textbooks, stand up all around the room and throw around a small football. This helped them clear their minds and then focus on the lesson again. Besides, she was quick to reply to any phone calls or emails from us and got rid of our worries about children quickly.When my son went to the 5th grade this year, we happened to pass her classroom. When she saw my son, she smiled, and she came out and hugged him. She generally loves all of the children in her classroom and that love really shows. I can only pray that my son will continue to get teachers just like her for the rest of his school years.21. With the teacher’s help, the writer’s son ______.A. became the best student in his class B. was interested in singing songs4C. quickly finished his 4th grade lessons D. improved his grades greatly22. Which of the following is NOT true about Miss Green?A. She regarded the students as members of a family.B. She had special ways to help students study.C. She was good at teaching football and music.D. She usually made a quick reply to parents’ emails.23. We can learn from the passage that ______.A. Miss Green didn’t teach the writer’s son in the 5th gradeB. Miss Green was the best teacher at the schoolC. all the students in the school liked Miss GreenD. the writer’s son had many teachers like Miss Green24. In the passage, the writer mainly tells us ______.A. what his son studied at school B. his son once had a good teacherC. how to be a good and popular teacher D. a teacher who liked playing with studentsBLocated in the middle of the northern lights belt, Tromso can offer some of the highest levels of northern lights activities on earth. Perhaps Tromso is the world’s best place for a Northern Lights Tour. Join one of our Northern Lights Holidays this winter. It could become one of the greatest experiences in your life. DESTINATION: Tromso county, Norway. PRICE: $450 per person. WHEN: 2nd September until 31st March. PICK-UP: Each evening at 6 PM beside your hotel. DROP-OFF: Earliest at 12 AM. When we have a sighting we often stay out later, at no extra cost. 5SIZE OF GROUP: Maximum 8 participants are recommended and normal, but not absolute. A small group allows more freedom in terms of chasing the northern lights. INCLUDED—Transportation each day in a comfortable car. —A meal each day. —All necessary equipment such as snowshoes, flashlight, water-filled bottle, woolen underwear, hat, warm shoes, warm stockings, and reindeer skin to lie on, if needed. —A guide who will do anything necessary to find the northern lights. EXCITING CHASEA Northern Lights Holiday means an intense and exciting chase-to the coast or deep into the wild, perhaps even to the Finnish border. Each day on a Northern Lights Tour we contact meteorologists shortly before departure to get accurate information. In order to find out where we will have best chances to see the northern lights. WE GUARANTEE A GREAT TRIPThe northern light is unpredictable, but we make sure that we will do everything to find it. Patience is a keyword on Northern Lights Tour. ECO-TOURISMWe offer ecologically sustainable and responsible tours. Travelling in small groups is an essential part of the eco-tourism concept, as small groups have less impact on nature and will not disturb the wildlife unnecessarily. 25. A small group is preferred for the following reasons EXCEPT that___________. A. a small group is free to run after the northern lightsB. a small group has less influence on natureC. a small group can be safer facing troubleD. a small group will not disturb wildlife26. The underlined word “it” refers to “___________”. A. the northern lights tour B. patienceC. equipment D. the northern light27. We can infer that___________. A. if tourists stay out late, they have to pay more6B. every tourist group is not sure to see the northern lightsC. every tourist group will get the money back if they don’t see the northern lightsD. the northern lights can be seen every day from 20th September to 31st March28. The passage is most likely to be taken from a(n) ___________. A. travel magazine B. news reportC. science textbook D. storybookCDo you think you are more intelligent than your parents and grandparents? According to James Flynn, a professor at a New Zealand university, you are! Over the course of the last century, people’s IQ test scores have gotten steadily higher --- on average, three points higher each decade. This improvement is known as the “Flynn effect”, and scientists want to know what is behind it.IQ tests are designed to measure general intelligence rather than knowledge. Flynn believes that intelligence partly comes from our parents and partly is the result of our environment, but the improvement in test scores has been happening too quickly to be explained by heredity （遗传）. So what has occurred in the 20th century to help people achieve higher scores?Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general and the learning of test-taking techniques that help us perform better on any test. Others have pointed to better nutrition. Babies now are born larger, healthier, and with more brain development than in the past. Another suggested explanation is a change in educational styles, with teachers encouraging children to learn by discovering things for themselves rather than just memorizing information, which improves their problem-solving skills. Flynn has limited the possible explanations after carefully examining test data and discovering that the improvement in scores has taken place in only certain parts of 7the IQ test. Test-takers are not doing better on the maths or vocabulary sections of the test; they are doing better on the sections requiring reasoning and problem solving. For example, one part of the test shows a set of shapes, and test-takers must find the patterns and connections between them.According to Flynn, this visual intelligence improves as the amount of technology in our lives increases. Every time you play a computer game, you are exercising exactly the kind of thinking and problem solving that helps you do well on one kind of intelligence test. So are you really smarter than your parents? In one very specific way, you may be.29. According to the passage, the “Flynn effect” is ________.A. a method used to measure intelligenceB. an increase in IQ test scores over timeC. the influence of hard work on intelligenceD. a theory that connects intelligence to health30. What is the function of the third paragraph?A. To list the findings of Professor Flynn’s research.B. To show other scientists’ opinion on Professor’s Flynn’s research. C. To list different theories explaining the increase in IQ scores.D. To describe how research was carried out in the measuring of intelligence.31. The writer believes that computer games _________.A. have discouraged people from taking exercise B. have made young people become less intelligentC. have helped improve people’s visual intelligenceD. have caused young people to have poorer vocabularies32. Which statement would Professor Flynn agree with?A. People today are taking easier tests.B. People today have fewer problems to solve.C. Not all aspects of intelligence have increased.D. The language ability of people has improved.8DA man enters a store to buy milk. He walks out of the store with milk. That is all— milk. At the same time, a woman enters the same grocery store also to buy milk. She buys it. But, she also buys chicken and lemons to make dinner that night. Then she remembers to buy food for her son to eat at school. She also gets a bottle of wine for drinks with friends and a birthday card for her husband's niece. Then she gets coffee for breakfast, ice cream for dessert and remembers stamps to mail the bills. And don't forget soap for the bathroom.And that is the difference between the female and male brains simply explained in a grocery store. Generally speaking, men do one thing at a time. Women do many. Doing many things at one time is often called “multi-tasking”, a very popular word these days.Now scientific research supports this theory about male and female brains. A recent study has confirmed what we have known all along—men and women think differently.Scientist at the University of Pennsylvania studied brain images of 949 people aged from 8 to 22 years old. They found that male brains have more connections on one side of the brain, or hemisphere. In female brain, they found more activity and connections between the right and left sides of the brain. The left side of the brain is known as the side of “reason” The right hemisphere is known as the “creative” side.Regina Verma is a professor at the University of Pennsylvania. She co-wrote the report. She says when women are asked to do something difficult they might use different parts of the brain. Men, she adds, generally use just one side of the brain.As a result, men generally deal directly with a problem.
