广东省深圳市中考英语题型专练•阅读理解
Have you ever stood beside the ocean and stared at the waves (波浪)? The way they move is changing! Nothing is more peaceful than watching the movement of water.
Every ocean has waves. Unless you are lucky enough to live by the sea, though, you probably can't watch the waves very often. How would you like to have your own wave machine? Making one is easy and a lot of fun.
Start with the following things: a glass bottle, water, food colouring, some dish soap, vegetable oil, paint thinner (涂料稀释剂), a cap for the bottle *Note: Use the paint thinner only when your parents agree. Put it away carefully. | |
Step 1: Using the dish soap, wash the bottle carefully. You want your sea to be nice and clean! | |
Step 2: Fill the bottle halfway with clean water. | |
Step 3: Now pm food colouring into the bottle. A few drops will colour the water. You might want to use blue or green. The prettiest colour is actually a mix of blue and green! | |
Step 4: Pour some vegetable oil into your bottle. Pour until the bottle is almost full. Then add some paint thinner until your bottle is full. | |
Step 5: Cap your bottle gently. |
Now that you have made your ocean, put your bottle on its side. Wait a minute. The water win be on the bottom. The oil and paint thinner mixture will be on the top. Now tip (倾斜) the bottle back and forth (反复来回) and watch the waves.
