Thirty years ago not many people would have dreamed of doing the repairs and decorations in their own homes. In those days labor was fairly cheap and most people would have thought it worthwhile to employ a professional painter and decorator, unless of course they were either very hand up or were in the trade themselves. Today, however, it is quite a different story. Men and women in all walks of life turn their hands to all sorts of jobs round the house including painting, papering, putting up shelves and wall units, and tiling walls and floors. Some people with no professional training of any kind have even successfully built their own houses. These jobs have been made easier today by the introduction of prepared materials, which require the minimum amount of skill to use. In every high street throughout Britain nowadays there is at least one “Do-it-Yourself” shop containing a vast range of timber, tiles, paints, wallpapers and floor coverings besides tools of every description including power drills and many accessories. “Do-it-Yourself” is a booming business; all these shops do a roaring trade and look like continuing to do so. Probably the main reason for the craze is the high cost of present-day labor and the shortage of building firms willing to do small jobs. Why did people employ professional workers to decorate homes thirty years ago?
| A．Because they could not do it themselves. |
| B．Because professional workers were very cheap. |
| C．Because they had no time. |
| D．Because professional workers could do much better. |
Thirty years later what changes took place?
| A．People could do everything themselves. |
| B．Few people chose to be a professional worker |
| C．People with no professional training successfully built their own houses. |
| D．New expensive materials required no skills at all. |
What caused the DIY craze?
| A．Young people liked to follow the fashion. |
| B．“Do-it-Yourself” is a booming business. |
| C．There were fewer building companies. |
| D．High cost of professional workers. |
What is the speaker telling us?
| A．How DIY comes into being. |
| B．Changes in building. |
| C．Changes in housing. |
| D．Great changes in these thirty years. |
You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.
Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle to the boat. Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat. It needs to be out far enough to catch the wind, but it shouldn’t flap (摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.
Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you are tacking, you must always keep the sail inside the boat.What should you consider first while sailing?
| A．Sailors’ strength | B．Wave levels |
| C．Wind directions | D．Size of sails. |
What does the word “It” underlined in Paragraph 4 refer to?
| A．The boat | B．The wind |
| C．The sail | D．The angle |
What do you have to do when sailing against the wind?
| A．Move in a straight line. |
| B．Allow the sail to flap. |
| C．Lower the sail. |
| D．Tack the boat. |
Where can you probably find the text?
| A．In a popular magazine. | B．In a tourist guidebook. |
| C．In a physics textbook. | D．In an official report. |
Brenda Bongos was a happy, artistic girl. She had one big dream—to play the drums in a band. But one big problem lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.
One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.
With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit（成套设备） and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.
It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.
Years later, when asked how she had achieved all this, she thought for a moment, and said: ''If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.''Why did Brenda try to play in the strangest places?
| A．Because she didn't want others to hear her play |
| B．Because she didn't mean to disturb others. |
| C．Because she didn't have her own room |
| D．Because she didn’t like her neighbors. |
Brenda started to give concerts _______.
| A．after she practiced in her space bubble |
| B．when she became part of the unique space journey |
| C．after she became a real musical astronaut |

Brenda became famous because ______.
| A．she was good at music and science |
| B．she became a real musical astronaut |
| C．she invented a special way of practice |
| D．she played well and had a talent |
It can be inferred from the text that: " _______".
| A．He laughs best who laughs last |
| B．It's never too old to learn |
| C．Two heads are better than one |
| D．One good turn deserves another |
Harvard researchers have created a tough, low-cost, biodegradable (可生物降解的) material inspired by insects' hard outer shells. The material's inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp ('虾) shells and proteins produced from silk, is called "shrilk." It is thin, clear, flexible and strong.
A major benefit of the material is its biodegradability. Plastic's toughness and flexibility represented a revolution in materials science during the 1950s and '60s. Decades later, however, plastic's very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years?
Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer(肥料), and so will enrich the soil.
Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.
Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they're exploring ways to use it in wet environments. They're also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They're even exploring combining it with other materials, like carbon fibers, to give it new properties.Paragraph I of the passage is mainly about shritk's_____.
| A．remarkable design |
| B．interesting name |
| C．major features |
| D．basic elements |
What has become a concern about plastic?
| A．Using it properly. |
| B．Producing it cheaply. |
| C．Developing its properties quickly. |
| D．Evaluating its contributions fairly. |
What are the inventors doing in the lab?
| A．Replacing carbon fibers with shrilk. |
| B．Testing ahrilk's use in wet conditions. |
| C．Making shrilk out of used household goods. |
| D．Improving shrilk's flexibility for medical purposes. |
Which of the following can be the best title for the passage?
| A．Recent Progress in Environmental Protection |
| B．Benefits of Insects in Scientific Research |
| C．The Harm of One-time Products |
| D．A Possible Alternative to Plastic |
San Francisco has its cable cars. Seattle has its Space Needle. And, Longview has its squirrel bridge. The bridge, which has attracted international attention, is now a local landmark.
The Nutty Narrows Bridge was built in 1963 by a local builder, Amos Peters, to give squirrels a way to cross the busy road without getting flattened by passing cars.
The original bridge was built over Olympia Way on the west edge of the library grounds. Before the bridge was built, squirrels had to avoid traffic to and from the Park Plaza office building where office staff put out a nutty feast for the squirrels. Many times, Peters and others who worked in and near Park Plaza witnessed squirrels being run over.
One day Peters found a dead squirrel with a nut still in its mouth, and that day’s coffee break discussion turned into squirrel safety. The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council(市政会).The Council approved, and Councilwoman Bess LaRiviere named the bridge “Nutty Narrows.”
After architects designed the bridge, Amos Peters and Bill Hutch started Construction, They built the 60-foot bridge from aluminum and lengths of fire hose(消防水带). It cost 1,000.
It didn’t take long before reports of squirrels using the bridge started. Squirrels were even seen guiding their young and teaching them the ropes. The story was picked up by the media, and Nutty Narrows became know in newspapers all over the world.
In 1983, after 20 years of use, Peters took down the worn-out bridge. Repairs were made and crosspieces were replaced. The faded sign was repainted and in July 1983, hundreds of animal lovers attended the completion ceremony of the new bridge.
Peters died in 1984, and a ten-foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.The Nutty Narrows Bridge was built in order to ________.
| A．offer squirrels a place to eat nuts |
| B．set up a local landmark |

What happened over the coffee break discussion?
| A．The committee got the Council’s blessing. |
| B．The squirrel bridge idea was born |
| C．A councilwoman named the bridge |
| D．A squirrel was found dead. |
What does the underlined phrase “teaching them the ropes” probably means in the text?
| A．passing them a rope |
| B．Directing them to store food for winter |
| C．Teaching them a lesson |
| D．Showing them how to use the bridge. |
What can we learn about Amos Peters?
| A．He is remembered for his love of animals. |
| B．He donated $1,000 to build the bridge |
| C．He was a member of the City Council |
| D．He was awarded a medal for building the bridge. |
Peanuts to This
Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”
Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real talk I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.
Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?
Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet! What did the author’s classmates think about his report?
| A．Controversial. |
| B．Ridiculous. |
| C．Boring. |
| D．Puzzling. |
Why was the author confused about the task?
| A．He was unfamiliar with American history. |
| B．He followed the advice and flipped a coin. |
| C．He forgot his teacher’s instruction. |
| D．He was new at the school. |
