根据短文内容，从题中所给的A、B、C、D四个选项中选出一个最佳选项。
I am Linda. Our home is slowly turning into a smart home, thanks to all kinds of cool and smart devices（设备）. Here are some of the ones I enjoy using the most.
First, our smart lights are fantastic. I can control them with my phone or just my voice—there is no need to get out of the bed to turn them off on a cold night! What’s really cool is that I can change their brightness and colours. For example, I set them to soft yellow when my kids are listening to bedtime stories and bright white when they are doing their homework.
Next, I’m a big fan of our smart door lock. Those days of searching for keys in the dark are gone! Now, we can unlock the door with a fingerprint or a password. It’s really convenient. And the best part is that we can create temporary（临时的） passwords for guests, so we don’t have to worry about giving out spare keys. These passwords will become invalid after the guests leave.
We also have a smart camera inside the house. It’s mainly for checking on our kids when we’re not at home. We can see what they are doing, and we can even talk to them through the camera! It makes us feel connected to them.
These smart devices are not just tools. They’re like our friends. They teach me that technology can bring both joy and safety to our daily lives.
21. How does the writer like the smart lights? （
A. Fantastic. B. Interesting.
C. Terrible. D. Ugly.
22. What is the best part of the smart door lock? （

B. People can create temporary passwords.
C. People can open it with their faces.
D. People can control it through phones.
23. Which of the following has the similar meaning to the underlined word “invalid”? （
A. Unfair. B. Unhappy.
C. Useless. D. Unpleasant.
24. What is the structure of the text? （
A. （p1）（p2）（p3）/（p4）（p5）
B. （p1）/（p2）（p3）/（p4）（p5）
C. （p1）（p2）/（p3）（p4）/（p5）
D. （p1）/（p2）（p3）（p4）/（p5）
