The problem is that the river is r 33 out of water! This happens when there’s not enough rain or s 34 for a long time. We call this a drought. During a drought, there’s not e 35 water for everyone and everything that needs it.
Some people say that the weather is changing q 36 in ways we didn’t expect, and this is making droughts w 37 . We call this c 38 change. It’s affecting our water resources, like the Colorado River.

六、任务型阅读
Answer the questions（根据短文内容回答问题）
Have you ever wondered what happens to your old computers, MP3 players and cellphones when they stop working or you want to upgrade to a new one
Many people simply throw them away. But did you know that people all over the world created a huge amount of electronic waste, called e-waste They made 41.8 million tons of it, but only recycled 6.5 million tons. That left 7.1 million tons of waste, and China was the second-largest producer with 6 million tons.
It’s important to be aware of e-waste because it can be both valuable and harmful. It’s like a hidden treasure trove called an “urban mine” because it contains metals like gold, silver, iron and copper that are worth a lot of money — over 322 billion yuan worldwide! These materials can be reused and help us save resources.
However, if we just throw away our electronics, they can release harmful chemicals into the soil and air. This can harm the environment and make people sick.
So, what can we do to reduce e-waste One way is to buy electronic devices that last longer. When you have old electronics you no longer need, like toys or old cellphones, you can give them to charity or find someone who can use them.
Additionally, some companies offer recycling programs where you can get discounts when you trade in your old devices for new ones. For example, Apple in China gives customers a discount if they bring in their used devices when buying new ones. The company fixes up the old devices and sells them at lower prices, which is great for both the environment and your wallet!
49．Why is it important to recycle e-waste
50．What is a bad effect of not recycling e-waste
51．We should buy cellphones that can be used for a long time, shouldn’t we
52．What does Apple in China offer customers as an incentive to recycle their old devices
53．What type of e-waste recycling method would you personally choose, and why
54．Which do you consider more when shopping: being environmentally friendly or the price Why
七、书面表达
55．Write a diary in at least 50 words（假设你是一名关注环保的学生，近期开始尝试在日常生活中实践绿色生活方式。请以日记的形式，记录你采取的一项环保行动以及这些行动对你的生活方式、环保意识或周围人产生的积极影响。不少于50词的短文，标点符号不占格）

55．(for reference)
April 17th Sunny
Today marks a new beginning for me. I decided to start being more eco-friendly, so I used my own water bottle instead of buying a new plastic one. It felt really good to do something good for the planet. When my friends saw it, they asked me why. I told them about how plastic hurts the environment and how we can help by using less. They were really interested and said they would try it too. It makes me happy to know that even small things like this can make a big difference. I’m going to keep doing my part to help protect our planet.
