Living a Life Full of Wild Adventures

Helen Skelton was brought up on a remote farm, and her family wasn't full of "runners and rock climbers". However, she has since travelled the world on 【1】 series of record breaking adventures. The former Blue Peter presenter has kayaked（劃皮劃艇）down the Amazon River, cycled to the South Pole and done a tightrope walk between the chimneys of Batter-sea Power Station in London. Now, Skelton 【2】 (share) the secrets of her success in a new book called Wild Girl: How to Have Incredible Outdoor Adventures.

【3】 she's got plenty of stamps in her passport, Skelton says you don't need to go to the Amazon or Antarctica in order to have an adventure - there's plenty to do here in the UK. She grew up in Cumbria, and would go bike-riding and skateboarding with her mum, as well as building rafts. She hopes to pass on these adventures to her own children.

Despite the title, Skelton says that the book isn't just for girls. She believes adventure is a leveller - an activity 【4】 men and women are equal. Adventures 【5】 also be educational. Skelton says when you're at the mercy of the elements you have to adapt and be flexible, which is a great lesson for life.

Of all the places she 【6】 (be) to, Skelton says the South Pole was particularly hard. "It's like living in a freezer. It's the windiest, driest, coldest place on Earth." Skelton explains, "You can't even put up your tent, which is your only shelter, 【7】 putting on huge gloves, otherwise you'll get a frostbite. 【8】 (put) up a tent in oven gloves isn't easy."

Her advice to any aspiring adventurers would be to "not worry about 【9】 comments other people might make. When I said I'm going to kayak the Amazon, people told me that's madness. And, if I had listened to them, I never would have done 【10】 of it. So just try."

【題目】 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. About 10 people die of a tobacco-related disease every minute. Most of these preventable deaths happen in low-income and middle-income countries. The World Bank says each of these countries has a total national income 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.

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 W HO 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 U. N. 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.

If the agreement succeeds, governments could put people who trade illegal tobacco products in prison-another cost to countries budgets.

【1】Where are people dying of a tobacco related disease mostly from?

A.Developed countries.B.Old countries.

C.Underdeveloped countries.D.New countries.

【2】Which of the following about the whole costs of smoking is NOT mentioned in the passage?

A.Destroying the environment.

B.Being harmful to human life.

C.Affecting the whole country’s economy.

D.Causing the illegal trade.

【3】What’s the main idea of Paragraph 6?

A.Some action has been taken by the WHO.

B.The illegal trade in tobacco products is harmful.

C.Young people who are addicted to smoking may commit a crime.

D.An agreement to end the illegal trade in tobacco products is being signed.

【4】Which of the following can be the best title for the passage?

A.Smoking Costs More than You Think

B.Different Ways to Stop Smoking

C.The Illegal Trade in Tobacco Products

D.Immediate Action to Stop Smoking
