Passage 1

The British summer is extremely beautiful. Trees，flowers，birds and butterflies make the whole country like a big garden. However, many British people have noticed that butterflies have been gradually disappearing from this picturesque scenery during the past several years. What has happened to them?

（1）Butterfly Conservation in the UK is running a survey to help answer this question.（此項關于蝴蝶的調查是由英國蝴蝶保護委員會開展的。）The result is more serious than people expected.（2）According to the survey, among 59 butterfly species found in the British Isl.es，more than three-quarters of them are suffering a declining population.（根據這項調查，在英國埃爾斯地區發現的59種蝴蝶中，超過四分之三的蝴蝶種類正面臨數量下降的危險。）Moreover, half of all butterfly species are on the verge of extinction. The numbers of butterflies have dropped to. a record low in the past three years largely because the summer in the UK is getting cooler and their habitat is also degrading. Fortunately, Britain is experiencing a long hot summer this year compared to the last few summers. Conservationists believe the warm weather will bring some benefit to the butterflies.

Sir David Attenborough, President of Butterfly Conservation, said,"（3）Butterflies in profusion tell us that all is well with nature. When they decline it's a warning that other wildlife will be soon heading the same way." The organizers hope the survey will help raise public awareness of the value of butterflies in the UK. Butterflies give an indication of the well-being of nature and the environment.（蝴蝶數量多說明大自然整體來說狀況良好。但是蝴蝶種類的下降也警告我們其他一些野生生物將很快面臨同樣的問題。組織者們希望這項調查能讓人們意識到蝴蝶的重要性。蝴蝶的現狀也反映了大自然和環境的狀況。）
