More and more people around the world are joining in dangerous sports. Some people climbed the highest mountains; some traveled into unknown parts of the world; some sailed small boats across the largest sea. Now some people begin to look for new excitement.

Bungee jumping (蹦极) and motorcycle racing (摩托车赛) are quite dangerous sports. Bungee jumping only lasts a few minutes or even seconds. You jump from a high place, 200 meters above the ground, and there is a rubber band (橡胶带子) tied to your legs. When you jump down, the rubber band pulls you up. About 2,000,000 people around the world have tried bungee jumping.

Why do people join in these dangerous sports? Some scientists say that it is because modern life has become safe and it is not interesting. In the past, people lived in danger. They had to go out and look for food, and life was like a fight but was interesting.

Many people think that there is little excitement in life. They live and work in safe places, buy food in shops, and there are doctors and hospitals to look after them if they become ill.

                         How much ancient forest (原始森林) do you have in your home?
      Are you sleeping on illegal trees-trees from the Congo? Is your kitchen table made from wood, which
has started social conflict in a distant African country? Are you literally flushing an ancient forest down the
toilet? Check out our interactive Forest House to see exactly where your household goods come from and
the forest-friendly alternatives. 
     The Earth's ancient forests are unique, centuries old regions that support countless plant and animal
species as well as native communities. But they are rapidly vanishing (消失) as the demand for wood and
paper grows. In fact, only 20 percent of the world's ancient forests remain-a very scary statistic. Our
comfy houses are contributing to the problem-in Europe, 50 percent of the tropical wood used in our
furniture, doors and window frames is logged illegally, often from irresponsibly managed ancient forests.
This wood often fuels corruption and social conflict and destroys the homes of endangered or
undiscovered species.
      Our interactive Forest House is a room-by-room (and garden) guide to wood in household products,
featuring everything from flowerboxes to guitars. You can also learn exactly why wood is "good" or "bad"
and print out our one-pager to stick on the fridge and check before you make that trip to IKEA. The Forest
House also lets you search by product, so if you're on the lookout for a new hat stand or toilet seat, you'll
know you should give teak a miss.
      In general, the safest wood is always Forest Stewardship Council (FSC) certified. This means that the
wood is from a sustainable (可持续的) managed forest and that the rights of indigenous peoples are
respected during the logging process. Some homeware stores such as IKEA and Home Depot (in the US)
have made commitments to only source FSC certified wood for their products.
1. Write out some wood products in your home.

D. 80%
3. In general, the safest wood is _______.
[ ]

D. Home Depot
4. From the passage, we know that _______.
[ ]
A. In Europe, 20% of the tropical wood used in our furniture is logged illegally.
