People around the world held many activities to celebrate David Attenborough’s 100th birthday on May 8. Celebrations included butterfly releasing, wasp (黄蜂) naming, music performances and a brand-new documentary.

David Attenborough is a well-known environmentalist and TV presenter. For many years, he has shown amazing natural scenery to audiences worldwide. He gained great popularity thanks to the BBC nature documentary Life on Earth. The show first came out in Britain in 1979 and reached America three years later.

The BBC held a grand celebration in London on his birthday. Many famous people and environmental lovers took part in the party, where musicians put on wonderful shows. A new documentary looking back at Life on Earth was also released at the same time.

A butterfly farm in England held a special activity too. Attenborough once shot a documentary there in 1983, which greatly helped the farm develop. Workers set free 100 rare blue butterflies to express their wishes. Besides, a new kind of wasp from Chile was named after him as a specialhonor.

Attenborough’s lifelong effort to record nature has won wide respect all over the world. His vivid documentaries let countless people appreciate natural beauty and care more about wildlife. He has always treasured every precious filming memory, and his spirit will always inspire people to protect our planet.

1.1.What do people do to celebrate Attenborough’s big birthday?

A Hold different events.

B Plant many trees.

C Build new farms.

D Catch small insects.

解析：选A。A 细节理解题。根据文章第一句“People around the world held many activities to celebrate David Attenborough’s 100th birthday”以及随后列举的放蝴蝶、黄蜂命名、音乐表演和新纪录片等活动，可知人们是通过举办多种多样的活动来庆祝，因此选项A“举办不同的活动”与原文直接对应。选项B“种植很多树”、选项C“建造新农场”和选项D“捕捉小昆虫”在文中均未出现，且与庆祝内容不符，不选。故选A。

2.2. When did the nature show Life on Earth arrive in America?

A In 1979.

B In 1982.

C In 1983.

D In 1985.

解析：选B。B 数字计算题。文章第二段明确提到“The show first came out in Britain in 1979 and reached America three years later.”，即节目1979年在英国首播，三年后也就是1982年到达美国。因此选项B“1982年”是准确答案。选项A“1979年”是在英国首播的时间，选项C“1983年”和选项D“1985年”则与原文“三年后”的计算不符，排除。故选B。

3.3. What can we know about the BBC celebration?

A It mainly served wildlife keepers.

B It released old animal pictures.

C It had musical performances.

D It invited local farmers only.

解析：选C。C 细节理解题。文章第三段描述了BBC在伦敦举行的盛大庆祝，并指出“musicians put on wonderful shows”，即音乐家们进行了精彩表演，因此选项C“有音乐表演”是文中的直接信息。选项A“主要服务野生动物饲养员”无依据，文中只说许多名人和环保爱好者参加；选项B“发布旧动物照片”与事实不符，原文提到发布了回顾《生命的进化》的新纪录片，并非旧照片；选项D“只邀请了当地农民”也与“many famous people and environmental lovers”相悖，因此均不选。故选C。

4.4.What influence do Attenborough’s documentaries have on people?

A People try to make movies.

B People begin to raise insects.

C People choose to travel abroad.

D People learn to enjoy and care about nature.

解析：选D。D 细节理解题。文章最后一段直接给出答案：“His vivid documentaries let countless people appreciate natural beauty and care more about wildlife.”，即让无数人欣赏自然之美并更加关心野生生物，这正是选项D“人们学会欣赏和关心自然”的同义转述。选项A“人们尝试制作电影”、选项B“人们开始饲养昆虫”和选项C“人们选择出国旅游”在文中完全没有涉及，所以排除。故选D。

5.5. What is the main purpose of this passage?

A To introduce a famous TV presenter.

B To report on a 100th birthday celebration.

C To encourage people to watch documentaries.

D To call on people to protect the environment.

解析：选B。B 主旨大意题。文章以阿滕伯勒的百岁生日为线索，开头总起全球举办多种庆祝活动，接着分别介绍BBC的庆祝仪式、蝴蝶农场的特别活动以及以他命名黄蜂的荣誉，最后一段虽提及其贡献与精神，但整体结构明显是在报道这一百岁生日庆典的盛况和具体庆祝方式。因此文章的主要目的应是选项B“报道一次百岁生日庆祝”。选项A“介绍一位著名电视主持人”过于宽泛，无法涵盖“百岁生日”这一核心事件；选项C“鼓励人们观看纪录片”并非文章着力点；选项D“呼吁人们保护环境”只是结尾的升华，并非篇章的主要写作目的，不选。故选B。
