二、 阅读理解：
（2025·辽宁·模拟预测）Sundews are beautiful little plants. They seem so small and harmless. All around the edges of their leaves are tiny hairs that shine with a shiny liquid (液体). To an insect this liquid looks like food. The insect lands on the leaf. The liquid is sticky (粘稠的) and the insect cannot get loose. The sundew wraps (包裹) itself around the insect and eats it.
Many years ago a scientist named Charles Darwin became interested in sundews. Would they eat only insects Darwin put small bits of roast beef on the sticky leaves. The plant ate them up. Darwin next tried drops of milk, bits of egg, the other foods. The sundew loved them all.
Sundews are just one kind of meat-eating plant. These plants trap insects in different ways. Some, like the sundew, use their tiny hairs. Others, like the pitcher plant, have bright colors that attract insects. When an insect lands on the colorful petals (花瓣), the insect starts falling. The insect slides down into the slippery insides of the plant. At the bottom is a pool of liquid. Special chemicals in this liquid turn the insect into food for the flowers.
Bladderworts are the meat-eating plants that live mostly in water. Bladderworts have trapdoors in their sides. When an insect comes near the tiny hairs on a bladderwort leaf, the trapdoor opens. The insect is pulled inside.
Some plants collect rainwater at their base. When insects go to get the water, they cannot run away. The plants are lined with a powder that makes it impossible for the insects to get away. A scientist named Durland Fish put four of the plants on a fence around a garden. Within eight days these four plants trapped 136 insects.

B．After the insect lands on the petals.
C．After the insect falls into a poor of liquid.
D．After the insect is attracted by the bright color.
4. What do the plants mentioned in the text have in common
