| No one knows when the first house was built and who was the first one to built the house. But the houses are changing all the time. ( )1. What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects (建筑学家) believe that they may come true one day. The only thing for sure is the houses will be as green as possible in the future. ( )2. Many architects in the world would like to build a house like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even make fresh air for the room. The"root"(根) of the house is deep under the ground. It uses the soil to control the room's temperature. ( )3. Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it's in the bright sun, the cover of the house will turn white to protect it from strong heat. During dark days, it turns dark and takes in as much light and heat as possible to produce energy. ( )4. This design is perhaps for the future of food. It has a garden on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every morning, you just need to walk outside and collect your meals. ( )5. Looking to the future isn't the only way to be green. Sometimes, the old ways of building houses can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier for hot air to run out of the chimney. | |

The Venus flytrap is not a large plant. It grows to be only about a foot tall. The plant has white
flowers in the spring, but it is the plant's leaves that make it so interesting. The ends of the leaves have
folding parts with stiff, tiny hairs (带小硬刺的可折叠部分). These are the plant's "traps (捕捉器)".
What does the Venus flytrap eat? As you might guess, the Venus flytrap eats flies (苍蝇). It also
eats spiders, ants, and crickets. The Venus flytrap makes most of its food with sun, air, and water,
just like other plants. Living things just give it extra nutrition (营养) to grow well in wetlands.
How does this plant trap and eat living things? The Venus flytrap uses a sweet liquid (液体) to
attract its food. When a fly lands on one of the plant's open traps, hairs on the surface make the trap
closed. As soon as the trap closes, the fly is dinner!
If you want to have your own Venus flytrap at home, you have to buy the plant from a special place.
You can't take a Venus flytrap from where it grows! There are laws about taking it out of the wild.
B. In the desert.
C. In the rocks.
D. In the sea.
B. It only eats spiders.

b. A fly lands on one of the plant's open traps.
