Can plant eat people? Probably not. But there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat- eating plant is the Venus flytrap(捕蠅草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(蒼蠅) touches one of the hairs, the leaf closes very quickly. Then the fly can’t go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things, especially nitrogen(氮). Animal meat has a lot of nitrogen. So some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea.
根據(jù)短文內(nèi)容判斷。
1. The Venus flytrap grows in wet parts of the United States.
2. The Venus flytrap is a kind of plant.
3. The underlined word “presses” probably means（擠、壓） in Chinese.
4. In the world, many animals eat plants but plants never eat animals.
5. From the passage, we know that not only animals eat plants, but also some plants eat animals.

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree 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 create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.
The Lizard house
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 dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑風(fēng)格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技術(shù)) can also help cut down energy use. For example, a chimney (煙囪) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.
【小題1】What is the best title (標(biāo)題) of the passage?
A. Green house of the future.
b. The greener, the better.
C. How to build green houses.
D. Changes of the houses.

A. with the root of a leaf.
b. with the energy from sunlight.
C. with the soil under the ground
D. with gardens on its walls.
【小題3】What will happen to the cover of the lizard house when it’s in the bright sun?
A. It will take in light.
b. It will produce energy.
C. It will turn dark.
D. It will turn white.
【小題4】The passage seems to tell us that meals at home in the future            .
A. will be more delicious.
b. need more cooks.
C. cost as much as possible.
D. will be greener.
【小題5】A chimney can be a useful air conditioner but it used to cause          .
A. pollution.   b. accident.     C. noise.      D. techniques.
