2 . When her classmates were having a good time, Molly sat at the picnic table alone. She remained embarrassed around her classmates. She seemed unsure of what to do or say, yet I could see her eyes longing for acceptance. Many students had already decided that her friendship would not be worth（值）the energy required to overcome the embarrassment. Others laughed at her. Most ignored her—except for one.

Brianna was making the other students laugh, as usual. “Brianna, do you see Molly down there? Would you mind walking down there and inviting her to come up here with the rest of us? I said.

Brianna sighed. I could tell she didn’t want to waste her precious time to do what I was asking of her, but I also knew her heart. She often thought of others before herself—a rare character for anyone, much less a kid.

Knowing this choice was hard for her, I pulled out a D-buck, our class currency（货币）. Though this was not the ideal way to deal with this situation. I needed her cooperation（合作）. “Here, I’ll pay you for your time.” I said to her. She offered an insincere smile, grasped the green paper, and headed down the hill.

As the rest of the children screamed and laughed, my eyes locked on Brianna as she neared the picnic table. Molly could be difficult to get along with, and I wouldn’t have been surprised if she sent Brianna back alone, refusing her invitation. When she encouraged herself to a standing position, I sighed with relief.

Minutes later, I felt a tap on my shoulder. “Here. Mrs. D.” Brianna handed me the D-buck. “Why?” I asked. “I shouldn’t keep this.” Her eyes fell to her feet, guilt showing from her quiet voice. “I don’t want Molly to think I only went to get her so I could earn the money. She’s my friend.”

A moment later, they were all laughing again, and who should I see among them, laughing for the first time that week? Molly.

3 . A single cigarette sold on a street corner may not cost a lot; however, the whole costs of smoking are huge.

First, consider the cost of human life. The World Health Organization says about 10 people die of a tobacco-related disease every minute. That speed adds up to almost six million people dying of such diseases every year.

Most of these preventable（可预防的）deaths happen in low-income and middle-income countries. The World Bank says each of these countries has a total national income（收入）of less than $12,746.

The World Health Organization says tobacco kills 6 million people yearly — a number that is expected to rise to 8 million by 2030 unless immediate action is taken.

For most people, stopping smoking is hard. Many began smoking as teenagers. They are used to it. Also, tobacco contains the powerful drug nicotine.

Studies show people who want to stop smoking can do so with different treatments. Some get help from electronic cigarettes, medicine or nicotine patches that reduce their desire for the drug.

But smoking costs more than the life of a person. It can affect the health of the whole country. The World Health Organization says low-income countries depend heavily on taxes from cigarettes. They use the money, in part, to pay the costs of health care for tobacco-related diseases.

But the illegal trade in tobacco products is further testing the economies of low-income countries. WHO officials say the illegal trade earns about $31 billion every year.

Douglas Bettcher is the director of the WHO’s Department for the Prevention of Non-communicable Diseases. He calls the illegal trade a monster with many heads. He says the trade enables young people to buy cigarettes at low prices, become addicted to tobacco and suffer from serious health problems. It also increases crime and reduces taxes.

The World Health Organization is strongly suggesting that the United Nations member states sign an agreement to end the illegal trade in tobacco products. Eight countries have agreed to the agreement. But the agreement of 32 other countries is still needed for it to become an international law.
