It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not.

In Kenya, researchers have found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.

Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing.

The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

1.According to the passage, which of the following statements is true?

A. Maasai people are a threat to elephants.

B. Kamba people raise elephants for farming.

C. Both Kamba and Maasai people are elephant hunters.

D. Both Kamba and Maasai people traditionally wear red clothing.

2.How did the elephants react to smell in the study?

A. They attacked a man with the smell of new clothing.

B. They needed time to relax when smelling something unfamiliar.

C. They became anxious when they smelled Kamba-scented clothing.

D. They were frightened and ran away when they smelled their enemies.

3.What is the main idea of this passage?

A. Elephants attack people who wear red clothing.

B. Elephants use sight and smell to detect danger.

C. Scientists are now able to control elephants’ emotions.

D. Some Kenyan tribes understand elephants’ emotions very well.

4.What can be inferred about the elephant’s behavior from this passage?

A. Elephants learn from their experiences.

B. Elephants have sharper sense of smell than sight.

C. Elephants are more intelligent than other animals.

D. Elephants tend to attack rather than escape when in danger.

We all have our ways of marking time. As a photographer, my life is measured from one story to the next. My oldest son was born in the middle of a long story about the Endangered Species Act. My daughter came along with a pack of gray wolves.

Twenty stories later, though, it’s the story in Alaska that I’ll remember best. It was the story about the loss of wilderness — and the story during which my wife Kathy got cancer. That’s the one that made time stand still. I stopped taking pictures on the day when she found that tumor (肿瘤). Cruelly, it was Thanksgiving. By Christmas, she had become very weak. Some days she was so sick she couldn’t watch TV.

Early examination saves time. But ours was not early. By the time you can feel it yourself, it’s often bigger than the doctor want it to be.

Cancer is a thief. It steals time. Our days are already short with worry. Then comes this terrible disease, unfair as storm at harvest time. But cancer also has the power to change us, for good. We learn to simplify, enjoying what we have instead of feeling sorry for what we don’t. Cancer even made me a better father. My work had made me a stranger to my three kids. But now I pay attention to what really matters. This is not a race. This is a new way of life and new way of seeing, all from the cancer.

In the end each of us has so little time. We have less of it than we can possibly imagine. And even though it turns out that Kathy’s cancer has not spread, and her prognosis (诊断) is good. We try to make it all count now, enjoying every part of every day.

I’ve picked up my camera again. I watch the sky, searching for beautiful light. When winter storms come, Kathy and I gather our children and take the time to catch snowflakes (雪花) on our tongues. After all, this is good. This is what we’re living for.

1.As a photographer, the author used to ______.

A. leave his daughter with a pack of gray wolves

B. express his love for his family in a special way

C. miss a great many important historical moments

D. devote much more to his career than his family

2.Why did the author decide to stop taking pictures?

A. To cure his own disease.                                    B. To spend more time with his wife.

C. To seek a better position.                                   D. To leave the wilderness alone.

3.What is the biggest change the cancer has brought to the author?

A. He treasured every bit of time with his family.

B. He has become a stranger to his children.

C. He takes his work more seriously.

D. He focuses more on medical care.

4.The author and his family catch snowflakes on their tongues probably because ______.

A. the snowflakes taste very good

B. snowflakes are what they feed on

C. they regard that as a way to enjoy life

D. there is beautiful light in the snowflakes
