II. Basic Listening Practice

1. Script

M: Now we have satellite and high-powered microscope, it’s easy to think we know everything about the world; but we still don’t understand EI Nino.

W: Right. Scientists all over the world over are even uncertain about the cause of the warm Pacific current that brings storms or drought—the mysterious EI Nino.

Q: Which of the following is true according to the conversation?

2. Script

M: Everyone is talking about environmental problem: acid rain, the greenhouse effect, holes in the ozone 1 layer. We should think positively 2. What can we do to improve things?

W: I agree. We could do a lot more to harness the sun’s energy for heating and lighting 3 in our homes. In Japan 43,000 solar roofs were installed in 2002.

Q: How do the man and the woman view the environment?

3. Script

W: We lived in Beijing some years ago. It was always difficult to keep the house clean with wind from the north blowing sand from the desert at us.

M: That’s why the Chinese government has been encouraging people to plant trees along the edges of the Gobi Desert. Now those trees act as wind barriers.

Q: What did the government encourage people to do?

4. Script

M: Many old refrigerators and cars are environmental hazards because they contain CFCs that destroy the ozone layer.

W: Yes, but government or organizations are helping 4 people to safely dispose of old refrigerators or, in the case of cars, to upgrade their air conditioning.

Q: What are government departments helping people to do?

5. Script

M: Hey, that’s an aerosol 5 spray you’re using on your hair! Build a bomb or set fire to the apartment to kill us quickly instead of making holes in the ozone, so we die of cancer.

W: Cool it, man. This spray doesn’t contain CFC s. And you’d better read a little more. In 2003 the hole in the ozone layer shrank by 20 percent, so there’s no reason to panic.

Q: What does the man mean?
