Luca Gramberini has been scuba-diving(戴水肺潛水) since he was a kid. His family owns a scuba company. For the past three summers, Luca has added gardening to his underwater activities. He helps run Nemo's Garden, a project to grow plants in the sea.

From May through September, Luca and other divers are working on Nemo's Garden in the Mediterranean Sea, 150 feet from the coast of Noli, Italy. Five large balloon-like objects, called biosphere(生物圈), hold plants such as beans and strawberries. The biosphere is filled with air and placed 20 feet below the surface. “My father came up with the idea because he loves gardening very much,” Luca said.

According to Luca, the sea is a good place to grow plants because underwater temperatures remain stable, changing little from day to night. The biosphere acts like greenhouses. Inside the air-filled biosphere, fresh water keeps evaporating(蒸發(fā)), providing the plants with a good environment to grow in. “We have already seen the plants, grow faster and better,” Luca says. “And there are fewer storms that can knock down the biosphere during the summer.”

Luca hopes Nemo's Garden will provide a new way of growing crops. “There is not enough land on the Earth,” he says. “And in many developing countries, bad conditions make it difficult for crops to grow.”

Though the project has just started, Nemo's Garden has achieved success and is moving to different areas. “We're going to try growing other plants,” Luca says. “We hope to set up biosphere in other countries. There are many possibilities.”

Have you ever felt angry with your parents? Do you sometimes quarrel with your parents? If you're upset or angry, try to keep yourself cool. Sometimes, the more you show your anger, the unhappier your parents will be. Try to come up with an idea that can solve your problem so that it won't happen again.

It might seem that your parents don't understand you—but don't give up. Remember that they don't really want to make things difficult for you. Your parents care about you, but sometimes it's just hard for them to know what you are thinking.

One of parents' jobs is to take care of you and keep you safe—until you're old enough to take care of yourself (but some parents have trouble giving up looking after their children even then)!

Usually, kids who quarrel with their parents learn to get along with them sooner or later. This is especially true if kids are able to make their parents know how they feel and what's important to them.

And remember that this may take time. It's not always easy. Talking with your parents about your opinions patiently—instead of shouting at them—will also make them listen to you more carefully. And you'll get respect(尊敬) and learn how to get along with them.

1.If kids want to get along with their parents, they should try to make their parents know ______ their thoughts are.(填單詞)

2.Translate the underlined sentence into Chinese.

_______________________________________

3.What does “this” in the last paragraph refer to?

_______________________________________

4.How can you make your parents listen to you more carefully?

_______________________________________

5.Give a proper title to the passage.
