While not an Olympic event, rock climbing is recognized by the International Olympic Committee as a sport.Rock climbing has been separated into several different styles and subdisciplines. At its most basic, rock climbing involves climbing a route with one39。s own hands and feet and little more than a cushioned bouldering pad for protection. This style of climbing is referred to as bouldering, since the relevant routes are usually found on boulders no more than 10 to 15 feet tall. As routes get higher off the ground, the increased risk of lifethreatening injuries makes additional safety measures necessary. Climbers will usually work in pairs and use a system of ropes and anchors designed to catch fallers.Rock climbing is a physically and mentally demanding sport that tests a climber39。s strength, endurance, and balance along with their mental control. It can be a dangerous sport and climbers are putting themselves at risk when they go climbing. However, the risk can be reduced by having the knowledge of proper climbing techniques and using specialized climbing equipment.Unit 5 Urban pulseLong conversationM: Hi Emily!

A smart city may mean one that uses data on traffic to ease congestion or one that aims to join up services to provide better information for citizens. For many it is about making cities greener and more efficient. It is partly a reaction to overcrowding and pollution and partly because in an everconnected world it makes increasing sense to hook entire cities up to the network.Masdar is a city that stands in the middle of the desert of Abu Dhabi in the United Arab Emirates. It is designed to be one of the most sustainable cities on the planet. With a solar power station at its heart and wind farms providing energy for it, it aims to be carbon free. Everything in the city, from water to rubbish, is measured and monitored, being a source of information. The city is built on a raised platform to allow its “digital plumbers” easy access to the system of advanced technologies that run it. It is pedestrianfriendly and entirely car free. The city is experimenting with a network of electric driverless podcars. The PRT — personal rapid transit — will run six meters under street level across the city. The buildings in the city have been designed by Norman Foster’s architecture firm, which designed a number of eyecatching buildings including The City Hall in London.It is hoped that 40,000 people will eventually live in the city, with up to 50,000 muting there each day.Unit 7 Time of technology：A blessing or a curse？Long conversationM: Oh!

My problem is I spent six hours on Saturday and five hours on Sunday at her apartment trying to teach her how to use her new electronic gadgets. I set up her telephone, Internet, TV, and DVD player. But she refuses to try and learn and she gets really confused. She just has no idea how to make any of them work.W: Oh, I see. My Aunt Patricia was the same. She didn39。t really want to learn — so it took six lessons plus nine phone calls to learn basic ! — how to open and close an , how to attach a document!M: Yes, my grandmother is like that, too. She refuses to learn. My grandfather always took care of all the electronic items – and since he passed away two years ago, she has to handle them by herself.W: OK, I have an idea! You need to get her liking electronic gadgets. Why not get her one of those video games made for families and kids. I bought my grandfather a Wii. He loves it. I got it all set up.
