六、阅读短文,完成下列任务。
Millions(数百万）of people turn off their lights at 8:30 p.m. local time for Earth Hour. This activity is often on the last Saturday of March.
The first Earth Hour started in 2007 in Sydney, Australia. Why is it so important? Because our planet is in danger. Climate change and the loss of forests and wildlife are serious problems. Earth Hour is a small but powerful（很有效的）way to remind people of these big problems.

Turning off lights for one hour may not save much electricity. But when millions of people join in, many streets go dark. Many famous landmarks also take part, such as the Eiffel Tower, Big Ben and the Sydney Opera House. The more people join, the greater the difference we make. So Earth Hour is not just about saving energy. It is a way to show our care for the Earth.

任务一:根据短文内容,选择正确的答案。
()1. Where did the first Earth Hour start?
A. In the US. B. In the UK. C. In Australia.
()2. The underlined word "landmarks" means "".
A. large parks B. big hotels C. famous places
()3. What is the best title of the passage?
A. How to save electricity at home B. A way to show our care for the Earth C. The history of Earth Hour
任务二:根据短文内容并结合生活实际,回答问题。
1. Why is Earth Hour so important?
2. What will you do to save energy in your daily life?

任务一:1. C 2. C 3. B
任务二:1. Because our planet is in danger.
2. 示例:I'll walk or ride a bike to school.

【分析】
首先，任务一为选择题，需根据原文定位信息解题：第1题是细节题，定位原文找第一个地球一小时的地点；第2题是词义猜测题，根据后文举例的著名建筑推断词义；第3题是主旨题，总结全文核心内容。任务二为简答题，第1题是细节题，直接提取原文原因；第2题是开放题，结合生活实际写出节约能源的做法即可。
【解析】
任务一：
1. 定位原文第二段第一句“The first Earth Hour started in 2007 in Sydney, Australia.”，可知第一个地球一小时始于澳大利亚，故选C。
2. 后文举例“the Eiffel Tower, Big Ben and the Sydney Opera House”均为著名地标，由此推断“landmarks”意为“著名地方”，故选C。
3. 原文最后一段点明主旨“It is a way to show our care for the Earth.”，结合全文内容，故选B。
任务二：
1. 定位原文第二段“Why is it so important? Because our planet is in danger.”，直接提取原因作答。
