2026 中考大时文阅读—跨学科专题 I.阅读理解 A Chicken eggs are just thin shells (壳), but you may be surprised at how strong they are. Let's do an experiment. What you need * Four eggs *Sharp scissors *Tape (胶带) *A bowl * Phone books or hardcover books What you do Step l: Dig a hole in the small end of each egg and make it larger to pour the eggs into the bowl. They are good for cooking. Wash and air dry the shells Step 2: Stick the tape around each egg's widest point, and then carefully break away shells between the tape and the hole Step 3: Put shells in a square at the four corners of a piece of paper, with the round end of the egg on top. Step 4: Add more books and see how strong the eggshells are. What has happened The strength of an eggshell lies in its shape. It's like a 3D arch (拱形) or dome (圆顶)which is one of the strongest shapes. The shape of the eggshell spreads pressure all over the whole egg rather than at one point. In fact, the shape of the eggshell is seen in many types of architecture (建筑设计),including doorways and large windows. The strong walls of the shell will support the weak point. At right conditions, the thin eggshell can even hold up 20 kg weight! 1. What does the experiment show us A. A small hole can make it easier to pour eggs B. Eggshells are thin. C. Books are harder than eggshells. D. Eggshells are strong 2. How many kinds of things are needed in the experiment A. Three B. Four C. Five D Six 3.Which picture is the right way to practice Step 3 4.

Here 's how to make a model submarine (潜水街) that dives and comes up from underwater like a real one. Materials Plastic bottle, Tape (胶带); Four coins, Thin rubber or plastic tube, Waterproof modeling clay(防水黏土)--not real clay, which dissolves (溶解) in water, Small scissors, Tub(盆). Steps 1. Cut two small holes on one side of the bottle, Tape coins to that side of the bottle. Remove cap, seal (密封) the tube to the bottle with clay. 2. Fill tub with water, put bottle in and let it fill with water. 3.Gently blow into the tube and watch what happens. Stop blowing and close the tube with your thumb. Lift your thumb and watch what happens Result When you blow, air pushes out water, the bottle becomes lighter and comes up. Bottle sinks when it fills with water and coins weight it down. Coins keep holes pointing downward, so air does not escape. When you stop blowing and seal the tube with your thumb, the bottle floats. Lift your thumb, air escapes through the tube and the bottle sinks. A real submari ... ...
