B Millie is watching a video about a raindrop's journey. Read the video script and choose the best answer for each question.
High up in the sky, there are dark, heavy clouds. A storm is on its way. Inside one of the clouds, several droplets of water are joining together to form a raindrop. The raindrop gets heavier and heavier. Soon, it is too heavy to stay in the cloud, so it falls to the ground. It's raining! The raindrop starts its long journey.
The raindrop bounces off a tree branch and lands on a man's hat. From there, it falls onto soft green grass. Here, it meets many interesting insects, but it can't stay in the grass for too long. Like all water, the little raindrop keeps flowing downward. It flows until it joins a small stream. The stream carries the raindrop to a river. Onwards goes the raindrop until it flows down into the big ocean.
Now the sun is coming out. The warm sun shines on the water and turns the raindrop into water vapour. The vapour rises from the ocean and travels up into the sky. The raindrop is back at its starting point.
But is its journey really over? No, it isn't! Up in the sky, the cold air turns the vapour back into tiny droplets. Once again, they join together to form a little raindrop. The raindrop gets heavier and falls. The cycle begins once more.
1 Why does the raindrop fall from the sky?
a Because the raindrop becomes too heavy for the cloud.
b Because the cloud gets too warm.
c Because the cloud gets too close to the ground.
2 What does the raindrop hit first on its trip down to the ground?
a It hits an insect. b It hits a river. c It hits a tree branch.
3 What happens to the raindrop after it gets to the ocean?
a It falls to the bottom of the ocean.
b It rises back up to the sky.
c It stays in the ocean.
4 Why isn't the raindrop's journey over when it gets back up to the sky?
a Because it rises higher up into the sky.
b Because it falls back to the ground again.
c Because it travels inside the cloud forever.
答案：【解析】：
这是一道阅读理解选择题，主要考查学生对英文文本的理解能力以及从文本中提取信息的能力。题目给出了一个关于雨滴旅程的视频脚本，并围绕这个脚本提出了四个问题。学生需要仔细阅读脚本内容，然后根据脚本中的描述，选择最符合题意的答案。
1. 对于第一个问题，“Why does the raindrop fall from the sky?”，学生需要从脚本中找到描述雨滴落下原因的部分，即“The raindrop gets heavier and heavier. Soon, it is too heavy to stay in the cloud, so it falls to the ground.”，然后对比选项，选出正确答案。
2. 对于第二个问题，“What does the raindrop hit first on its trip down to the ground?”，学生需要找到描述雨滴落下过程中首先撞击的物体的部分，即“The raindrop bounces off a tree branch”，然后对比选项，选出正确答案。
3. 对于第三个问题，“What happens to the raindrop after it gets to the ocean?”，学生需要找到描述雨滴到达海洋后发生的情况的部分，即“Now the sun is coming out. The warm sun shines on the water and turns the raindrop into water vapour. The vapour rises from the ocean and travels up into the sky.”，然后对比选项，选出正确答案。
4. 对于第四个问题，“Why isn't the raindrop's journey over when it gets back up to the sky?”，学生需要理解雨滴的循环过程，即雨滴在变成水蒸气升上天空后，又会因为冷空气而变成小水滴，再次形成雨滴并落下，然后对比选项，选出正确答案。
【答案】：
1. a Because the raindrop becomes too heavy for the cloud.
2. c It hits a tree branch.
3. b It rises back up to the sky.
4. b Because it falls back to the ground again.
