One cold night,I was growing sick of my life in San Francisco. There I was walking home around one o'clock in the morning after a 1 practice at the the?atre. With the opening night only a week away,I was still learning my lines by heart. I was having 2 han?dling my parttime job at the bank in the daytime and my acting at night at the same time. As I walked,I thought seriously about 3 both acting and San Francisco. I had 4 too much of the city life.

As I walked down the 5 streets under the tall buildings,I felt very small and cold,so I began 6 both to keep warm and to keep away from any possible robbers. Very few people were still out 7 a few homeless people under blankets.

About a block from my 8 ,I heard a sound be?hind me. I 9 quickly,half expecting to see some?one with a knife or a gun. The street was empty. All I saw was a shining street light. Still,the noise had made me 10 so I started to run faster. Not until I reached my apartment building and unlocked the door did I 11 what the noise had been. It had been my wallet 12 to the sidewalk.

Suddenly I wasn't cold or tired any more. I ran out of the door and back to where I'd heard the noise. Al?though I searched the sidewalk 13 for 15 minutes,my wallet was 14 to be found.

Just as I was about to quit the 15 ,I heard the garbage truck stop to the sidewalk next to 16 When a voice came from the inside, "Alisa Camcho?" I thought I was dreaming. How could this man know my name? The door opened and out jumped a small blonde man with an 17 look in his eyes. "Is this 18 you're looking for?" He asked,holding up something like a wallet.

Plants have family values,too,it seems,with new research sug?gesting they can recognize close relatives in order to work together.

An ability to tell family from strangers is well known in animals,allowing them to cooperate and share resources,but plants may pos?sess similar social skills,scientists believe.

Susan Dudley and Amanda File of McMaster University in Ontario? Canada,report they have demonstrated for the first time that plants can recognize their kin.

This suggests that plants,though lacking recognition and memory,are capable of complex social interactions.

"Plants have this kind of hidden but complicated social life," Dudley said.

The study found plants from the same species of beachdwelling wild flower grew aggressively alongside unrelated neighbours but were less competitive when they shared soil with their families.

Sea rocket,a North American species,showed stronger and healthier root growth when planted in pots with strangers than when raised with relatives from the same ma?ternal (母系的) family,the study found.

This is an example of kin selection,a behaviour common in animals in which closely related individuals take a group approach to succeeding in their environment,the researchers said.

Kin selection also applies to competition,because if family members compete less with each other,the group will do better overall. "Everywhere you look,plants are growing right up next to other plants," Dudley said. "Usually it's a case of each plant for itself. But sometimes those plants are related,and there are bene?fits to not wasting resources on being competitive,and there is not really a cost to not being competitive as long as your neighbour is also not being competitive."

Learning and memory appear to be important for kin recognition in animals,but this isn't an option for plants,she noted.

Some researchers speculate (猜測(cè)) that plants communicate through their roots,identifying themselves using tiny chemical signatures specific to each plant's family.

5. What's the main idea of the passage?

A. Studies find plants can recognize and communicate with relatives.

B. Kin selection is important for plants.

C. Animals can recognize and memorize their relatives.

D. Competition asks plants to recognize their relatives.

6. Which of the following is NOT right about animals' social skills?

A. Animals can recognize and memorize their relatives.

B. Animals' social skills are to cooperate and share resources.

C. Animals' social skills can recognize close relatives to work together.

D. Animals' social skills are no use at all.

7. Plants' kin selection is to .

A. grow well
