【正文】 t is that?” This time, the son said to his father in a low and cold tone, “It?s a crow, a crow.”[ After a moment, the father yet again asked his son for the fourth time, “What is that?” This time his son shouted at the father, “Why do you keep asking me the same question again and again? I have told you already, ?IT IS A CROW.? Are you not able to understand this?” A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page. “Today my little son aged 3 was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I did not at all feel angry, but instead felt affection for my son.” If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. From today say this aloud, “I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the best way no matter how they behave.” 24. The writer mainly intends to .

In some cases, you can even build your own solar panels (太陽(yáng)能電池板 ), although the amount that you can effectively DIY home solar depends on how much you want to power. Making your own solar panel is a timeconsuming process and requires some electrical skills. However, it can also be very rewarding—learning to build your own panel is a great way to understand how solar electricity is generated (產(chǎn)生 ). Before you can build your own solar panels, you first need to understand how solar cells generate electricity. Once you?ve bought individual solar cells (they can be purchased online), the basic process for building your own solar panel goes like this: Prepare the backing (底板 ) for your panel. Many DIY solar panel builders prefer to use a wooden board as the base for their solar cell. You?ll need to drill holes in the board so that the wires for each cell can pass through. Wire your solar cells together. This requires some experience with electrical work. Use a soldering iron (烙鐵 ) to attach wire to the solar cells and then link each of the cells together. Attach cells to your backing. If possible, attach each solar cell to the backing individually. This makes it easier to replace a single cell in the event that bees damaged or is not operating properly. At this point you have a functional solar panel that can produce electricity when the sun shines. However, a solar panel by itself is not useful. If you are trying to generate electricity to power devices in your home, you need to pair your panel with an inverter (換流器 ) that will turn direct current (DC) power from the sun into the alternating current (AC) power used in most modem electronic devices. 28. What does the author think of building DIY solar panel in the first paragraph? A. It is easy. B. It is necessary. C. It is mon. D. It is worthwhile. 29. What?s the first step of building your own solar panels? A. Master the advanced knowledge of management. B. Buy individual solar cells. C. Prepare the backing for your panel. D. Drill holes in the wooden board. 30. Why are solar cells connected to the wooden board separately? A. To produce more power. B. To substitute damaged cells easily. C. To attach cells to the backing tightly. D. To pass through the wooden board easily. 31. What can be inferred from the text? A. People with electrical skills have advantages over those without in DIY solar panels. B. A functional solar panel can give power to your home devices directly. C. How to pair an inverter depends on how much you want to power. D. A wooden board is a must for your own solar panels.
