2026年孟建平各地期末试卷精选八年级英语下册外研版第68页答案
C
Do you know that the sun's warmth is a useful form of energy? Want to try using it yourself? Let's do a cool project—making a solar tower(太阳能塔)!
You can try this project at home. You just need some tape, a pin(别针), paper, three cans and two big thick books.
Now, we're going to build the solar tower. First, make a pinwheel(玩具风车) from a piece of square paper. In the second step, cut off the tops and bottoms of the cans, then place the cans on top of each other and stick them together. Next, use a pin to connect the pinwheel with the tower. Finally, put the can tower on top of the books, which are 5 cm apart from each other. So there's a gap at the bottom, allowing the air to enter the tower.
Now, all we have to do is set the whole thing near a window, where there's direct sunlight. When the sun shines on the tower, it gets hot and warms the air in it. The warmer air moves upward through the tower and makes the pinwheel turn around as it passes by. Then cooler air comes in through the gap from the bottom of the tower, gets heated up, and rises, so the cycle goes on. This is how it works. Isn't that amazing!
So next time you feel the warm sun on your face, remember that it's more than just a nice feeling—sunlight is a powerful and useful source of energy.
