答案

1. B 文章中提到:“There is an old way to measure time. It's a sundial. A sundial uses the sun to tell time.”这表明日晷是一种古老的方法,通过利用太阳来测量时间。因此,选项B“一种利用太阳测量时间的古老方法”是正确的。
2. D 文章开头提到:“We use clocks, watches, and mobile phones to tell time.”这表明在现代,我们使用时钟、手表和手机来查看时间。因此,选项D“时钟、手表和手机”是正确的。
3. B 文章中提到:“The sun throws a shadow on the sundial.”这里的“shadow”指的是太阳在日晷上投下的阴影。阴影是太阳光线被阻挡后形成的黑暗区域。因此,选项B“太阳光线被阻挡形成的黑暗区域”是正确的。
三、根据短文理解和自己的思考,回答问题。
If you were in a desert without clocks, how would you use nature to tell time?
I would use the sun and shadows to tell time, just like a sundial. 文章中提到:“A sundial uses the sun to tell time. The sun throws a shadow on the sundial. In the morning, the shadow is long. At noon, the shadow is short. In the afternoon, the shadow is long again.”这说明日晷通过观察太阳的位置和影子的长度来判断时间。在沙漠中,没有时钟的情况下,我们可以利用太阳的位置和影子的长度来估计时间。
