LIKE many teachers, Cristi Derow and Jennifer Bradley have spent most of their careers giving classroom lectures to students who sat passively in their seats.
The Lewisvillle, Texas, school teachers were aware that the hours they spent on preparing lessons were too often wasted on many students. So Forestwood High School, Texas, used the “flipped (翻转的) classroom” method of instruction. “We’ve completely done away with our lecture,” Derow said. And homework assignments “are all done in class,” Bradley said.
With the flipped concept, a student’s usual homework assignment is to watch pre-recorded lectures on their computers or smart phones.They walk into class ready to discuss the topic, collaborate(合作) with other students and work on assignments based on what they learned from the video. Free from lecturing, the teachers can use class time to look deeper into the subject and focus on difficult concept. As students change from a passive to an active role, they learn critical thinking skills, learn to collaborate and become independent learners.
Instead of doing homework assignments alone at home, students are now “working together, talking about it,” Bradley said. “If they don’t agree on an answer, they debate it and have to justify their answers. It’s a higher level of learning.”
Her students give the flipped classroom high marks.
Sarah Lee, 14, watches the 30-minute videos on a home computer. She likes the ability to rewind the tapes if she doesn't understand a concept. She also likes being able to watch the lessons on her own schedule.
One of her classmates, Dawson Depperschmidt has the same idea and thinks the time she spends in the classroom is more productive. “It gives us more time to learn at school,” Dawson said. “You get more in-depth in class.What can we conclude from the first two paragraphs?

Strange things happen when you travel, because the earth is divided into twenty-four zones. The time difference between two zones is one hour. You can have days with more than twenty-four hours and days with fewer than twenty- four hours. You can have weeks with more than seven days and weeks with fewer than seven days.
If you make a five-trip across the Atlantic Ocean , your ship come into a different time zone every day. As you come into each zone, the time changes one hour. If you travel west, you set your watch back. If you travel east, you set it ahead. Each day of your trip has either twenty-five or twenty-three hours.
If you make a trip by ship across the Pacific Ocean , you cross the International Date Line. This is the point where a new day begins when you cross the line, you change one full day. If you travel east, today becomes yesterday, if you travel west it is tomorrow.Something interesting will happen to the time if you travel because .

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.Why did humans destroy rainforests in the past hundred years?
| A．They tried to get crops and paper |
| B．They needed other products |
| C．They wanted to raise farm animals |
| D．They aimed to get three major resources. |
Rainforests can help to adjust the climate because they________.
| A．reflect more heat into the atmosphere |
| B．bring about high rainfall throughout the world |
| C．rarely cause the temperature to drop lower than 16℃ |
| D．reduce the effect of heat from the sun on the earth |
What does the word “this” underlined in the third paragraph refer to?
| A．We will lose much more than we can gain. |
| B．Humans have begun destroying rainforests. |
| C．People have a strong desire for resources. |
| D．Much carbon dioxide comes from burning rainforests. |
It can be inferred from the text that________.
| A．we can get enough resources without rainforests |
| B．there is great medicine potential in rainforests |
| C．we will grow fewer kinds of crops in the gained land |
| D．the level of annual rainfall affects wind patterns |
What might be the best title for the text?
| A．How to Save Rainforests |
| B．How to Protect Nature |

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily. Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably. For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

| A．warmly welcomed at the airport |
| B．offered a ride to his home |
| C．treated hospitably at his home |

I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves. She made me promise that I would think seriously about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued to believe that I had cheated on the test.The story took place exactly ____ .

We all remember seeing hitchhikers（搭便车的人）, standing by the side of the road, thumb sticking out, waiting for a lift. But it is getting rare nowadays. What killed hitchhiking? Safety is often mentioned as a reason. Movies about murderous hitchhikers and real-life crime have put many drivers off picking up hitchhikers. That no single women picked me up on my journey to Manchester no doubt reflects the safety fear: a large, strangely dressed man is seen as dangerous.
But the reason may be more complex: hitchhiking happens where people don’t have cars and transport services are poor. Plenty of people still hitchhike in Poland and Romania. Perhaps the rising level of car ownership in the UK means the few people lift hitchhiking are usually considered strange. Why can’t they afford cars? Why can’t they take the coach or the train?
Three-quarters of the UK population have access to a car; many of the remainder will be quite old. The potential hitchhiking population is therefore small. Yet my trip proves it’s still possible to hitchhike. The people who picked me up were very interesting-lawyer, retired surgeon, tank commander, carpenter, man who live in an isolated farmhouse and a couple living up in the mountains. My conclusion is that only really interesting people are mad enough to pick up fat blokes in red,
spotted scarves. Most just wanted to do someone a good turn; a few said they were so surprised to see a hitchhiker that they couldn’t help stopping.
The future of hitchhiking most likely lies with car-sharing organized over the Internet, via sites such as hitchhikers. org. But for now, you can still stick your thumb out(actually, I didn’t do much of that, preferring just to hold up my destination sign) and people-wonderful, caring, sharing, unafraid people-will stop.
In the UK, with its cheap coaches and reasonable rail service, I don’t think I’ll make a habit of it. But having enjoyed it so much, I’m ready now to do a big trip across Europe and beyond. In the 1970s a female friend of my wife’s hitchhiked to India. How wonderful it would be to have another go, though Afghanistan might be a challenge. I wish I’d got that tank commander’s mobile number.The author tried to hitchhike but was rejected by single women drivers because_____________ .
| A．they were not heading towards Manchester |
| B．they thought most hitchhikers were dangerous |
| C．hitchhiking had been forbidden and they didn’t want to break the law |
| D．he was a strong man in strange clothes who seemed dangerous |
Which of the following statements is NOT true according to the passage?
| A．That some people refuse hitchhikers may reflect the safety fear. |
| B．Car ownership levels are lower in Romania than in the UK. |
| C．40% of UK people don’t have access to cars. |
| D．Increased car ownership has reduced the need for hitchhiking. |
The “fat blokes in red, spotted scarves” in Paragraph 3 most likely means .
| A．murderous hitchhikers |
| B．friendly and talkative hitchhikers |
| C．typical hitchhikers |
| D．strange hitchhikers like the author |
According to the author, future hitchhikers are more likely to .
| A．visit websites and find people to share cars with |
| B．stand by roads with their thumbs sticking out |
| C．stick out signs with their destinations written on |
| D．wait for some kind people to pick them up |
