1st Period: 

1st Period The nature of things--- environmental concerns

Setting Goals : 

Setting Goals In this chapter you will learn how to identify the purpose of a language task. express concern and dissatisfaction about specific problems. state plans and intentions to solve a problem. develop realistic plans and prioritize them. identify contrasting viewpoints.

Getting Started: 

Getting Started What do I think about the topic? What do I know about the language?

Language Learning Strategy: 

Language Learning Strategy Brainstorming Step 1: Carry out the learning strategy Step 2: Determine the benefits of the task Step 3: Summarize the purpose of the task

Language you can use: 

Language you can use Expressing concern / dissatisfaction Using new language

Listening Task : 

Listening Task Discussing the Environment Listen for the 1st time Listen for the 2nd time

Video : 

Video Viewing Task 1 Watch the video. Try to understand and remember the following terms. Golden Gate Bridge Golden Gate straits rush-hour stuck in traffic traffic congestion traffic jam In a Traffic Jam

Video : 

Video JAMES HATTORI, HOST The spectacular1 vermilion2 orange span3 of the Golden Gate Bridge. Hi, everybody. I'm James Hattori. Welcome to NEXT@ CNN, this week from San Francisco's world famous landmark4, at the mouth of the Golden Gate straits5. Forty-two million vehicles a year cross this bridge. That gives you an idea of the often nightmarish6 traffic drivers face around here. And, of course, we're not alone. Natalie Pawelski has the numbers on what it costs Americans to cope with7 rush-hour8 traffic, in time & money. Viewing Task 2

Video : 

Video NATALIE PAWELSKI, CNN ENVIRONMENT CORRESPONDENT If you think traffic is getting worse in your town, you're probably right. TIM LOMAX, TEXAS TRANSPORTATION INSTITUTE There's a combination of factors. It's the amount of people, the amount of roadway that is there. It's sort of a demand/ supply relationship. You can think of it that way, and there's a lot more demand than there is supply.

Video : 

Video PAWELSKI The annual Urban Mobility Report from the Texas Trans- portation Institute finds in the average American city people traveled 85 percent more miles by car in the year 2000 than they did in 1982. And rush hour drivers are now wasting an average of 62 hours a year stuck9 in traffic. Now that's not total travel time, that's just the extra time spent going slow or going nowhere because of traffic congestion10.

Video : 

Video The study says the worst traffic is in Los Angeles where the average rush hour driver loses 136 hours a year, more than three work weeks, to traffic jams11. The runners up in the time drained category San Francisco, D.C., Seattle, Houston, San Jose, Dallas, New York, Atlanta and Miami where the average rush hour driver loses an extra 69 hours a year stuck in traffic.

Video : 

Video LOMAX Once you get to a big system, it's difficult to maintain12 the pace13 of the roadway and transit system development and you wind up14 falling behind. More congestion is typical in bigger cities. PAWELSKI (on camera) The report says traffic jams aren't just annoying15, they are expensive. For the 75 cities studied, researchers added up16 all the extra time and fuel wasted because of traffic conges- tion. The price tag17 they figure is almost $68 billion a year.

Leading In : 

Leading In I am a passenger on the spaceship Earth. ---- R. Buckminster Fuller, Operating Mannual for Spaceship Earth The nation that destroys its soil destroys itself. ---- Franklin D. Roosevelt, letter to state governors, February 26, 1937 We have forgotten how to be good guests, how to walk lightly on the Earth as its other creatures do. ---- Stockholm Conference, Only One Earth, 1972

Leading In : 

Leading In In what ways are we humans not “good guests” who “walk lightly on the Earth”? How are we destroying the environment? What can we do to save the environment?

Setting Goals : 

Setting Goals In this chapter you will learn how to use ecology-related vocabulary. use new words as soon and as often as possible. work with other students to think of solutions to environmental problems.

Video Precious Water Supply in Jordan HATTORI In a lot of countries, people have water delivered to their homes as a luxury1. In the Middle East country of Jordan, water delivery is a necessity. Richard Roth reports on a growing nation that has already outstripped2 its water supply.

Video: 

Video RICHARD ROTH, CNN CORRESPONDENT Delivery day. Not of a luxury item but a basic necessity of life water. Tanker drivers rush through the city of Amman with precious cargo3. Amman is under the most restricted water controls of any large city in the world. Residents receive water pumped only once a week by the city. If they want more, they have to buy it. Jordan’s surgeon Saeb Hammoudi provides a nice home for his family of five, along with the maid4. But he still must buy more water from the government.

Video: 

Video SAEB HAMMOUDI, AMMAN RESIDENT It’s not enough. Once weekly for a household5, maybe it’s not enough. We need more than that. But then the government has to find the water to pump daily.   ROTH Many other families in Jordan can’t afford to purchase extra quantities of water. “Everything involving water is a problem,” Nasara (ph) says. She saves every drop for cooking and cleaning in an extended family household of 17 people.

Video: 

Video Even delivering extra water in Jordan is no easy task. Hauling water to a branch of the Bank of Jordan resembles a daring6 daylight robbery7. Leaks in the house, though, are an example of how water is lost due to poor infrastructure. Finding water in Jordan is like looking for a needle in the desert. Jordan receives about four inches of rain annually. A bad drought8 has added to the woes of a dry land.   PROF. ELIAS SALABH, JORDAN UNIVERSITY We don’t have enough (UNINTELLIGIBLE). The geography dictates9 whatever water resources we have.

Video: 

Video  ROTH In order to survive, Jordan has had to rely on its neighbors in what is a tough neighborhood. But hope is not dead. At the Earth Summit, Jordan and Israel reached an agreement to build a pipeline10 to pump water from the Red Sea in order to save the Dead Sea, which is rapidly ebbing away. And also, eventually a dam, similar to this one, to be called the Unity Dam, will be built. Water, the currency11 for a deal between Israel and Jordan, and then providing electricity for Syria.

Video: 

Video But analysts say the struggle for water will continue to be a source of political and economic tensions12, especially in the Middle East. And Jordan has little to bargain with. Jordan is on a top 10 list it would rather not be on, among those countries with the least available amount of water. Twenty-five years ago, the Wahde (ph) River surged through here in the capital. Now it’s all dried up. Looking into a future that’s not so sunny is Jordan’s minister of water and irrigation13. He can see rooftops covered not just with satellite dishes, but water storage tanks. And he knows Jordan’s population will double by the year 2020, far outstripping water demand and supply.

Video: 

Video   ROTH Jordan is working hard to manage the scarcity of water. The prime minister opened a new multimillion-dollar expanded sewage treatment center. Turning waste water into a renewable resource is part of sustaining14 basic needs here. If successful, something to write home about.

Video: 

Video   Discussion 1. What do you think about the water shortage in Jordan? 2. Can you give some suggestions on how to save water?
