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(市政會(huì)). The Council approved, and Councilwoman Bess LaRiviere jokingly named the bridge “Nutty Narrows”After architects designed the bridge, Amos Peters and Bill Hutch started construction. They built the 60­foot bridge from aluminum and lengths of fire hose(消防水帶). 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 known in newspapers all over the world.In 1983, after 20 years of use, Peters took down the worn­out 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 ten­foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.20.

The group of businessmen cooked up the squirrel bridge idea and formed a committee to ask the blessing of the City Council.”可以看出在此期間，建松鼠橋的想法產(chǎn)生了。故選B。22D詞義猜測(cè)題。根據(jù)本句的“Squirrels were even seen guiding their young”看出，是教小松鼠如何使用這個(gè)橋。故選D。23C細(xì)節(jié)理解題。倒數(shù)第二段的“Repairs were made and crosspieces were replaced”看出數(shù)年之后，這座橋得到了重修。故選C。24A推理判斷題。從最后一段的Peters died in 1984, and a ten­foot wooden squirrel sculpture was placed near the bridge in memory of its builder and his devotion to the project.看出，人們?cè)跇蚋浇藿ǖ裣駚?lái)紀(jì)念A(yù)mos Peters對(duì)動(dòng)物的這份愛(ài)心。故選A。.One possible version：Our Art FestivalLast_month_our_class_took_part_in_the_Art_Festival_of_the_school. We had a class meeting first, discussing what to perform in the festival. My classmates had several ideas such as putting on a drama, singing or dancing. As many of us were eager to participate, drama was our final choice. Preparations started right after the discussion. Though most of us were new to drama, we all had the confidence to try. All of actors and actresses began to practice the play we chose. Meanwhile, other classmates were preparing the stage properties like costumes and other decorations. Our monitor even made some lovely hats for the drama.The big day finally came. Every actor and actress performed at their best, impressing the audience greatly. Cheers and applause rose as we went up to receive the first prize. Our dream came true with the joint effort throughout the whole process.
