Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.

Harmer, a professor in the University of California at Davis, Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.

By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.

The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably tack the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.

When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day or on the other side at night. A plant growth-regulating hormone (激素), called auxin, appears to be a key driver.

The “dance” to the sun cycle obviously slows when the sunflower matures (成熟) and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.

“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.

“The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said “We’re currently testing this idea.”

1.Why did Harmer do the experiment on sunflowers?

A.To see how sunflowers grow up B.To show what sunflowers’ genes are.

C.To study why sunflowers track the sun. D.To check if sunflowers swing in cloudy days.

2.What does the underlined word “staking” probably mean in Paragraph 3?

A.breaking B.controlling C.growing D.searching

3.What is the result of sunflowers being stopped from moving?

A.They will produce a number of new genes. B.They will grow faster than usual.

C.They won’t swing back though set free. D.They won’t grow well.

People sometimes like to read stories of dogs very much. They think that dogs are much cleverer than cats, sheep, cows or other animals in their homes.

One of my close friends, Bob, has a very large police dog named Jack. Every Sunday afternoon, Bob and Jack have a walk in the park nearby. Jack likes these walks very much. One Sunday afternoon, I paid a visit to my friend. I stayed there for a long time and my friend and I had much more talk with each other than ever before. Soon it was time for them to take a walk in the park. We forgot that. Jack became worried about it. He walked around the room several times and then sat down in front of me and looked at me. But I still paid no attention (注意) to him. I went on talking with my friend. At last, Jack could not wait any longer. He went out of the room and came back a few minutes later.
