Wait a minute, we’ve got these photos _______.（单选）

听力原文：M: Hey, Sue. I was wondering if you could fill me in on Monday's class. I had to go the dentist for an emergency and I missed Prof. Smith's lecture. What was it on?

W: It was pretty interesting. She talked about volcanoes, active volcanoes, under the -- uh -- West Antarctic ice sheet.

M: There ere active volcanoes under the ice?

W: Apparently so. She said they help protect the ice sheet and prevent melting. Flooding would be pretty bad if that ice melted, not only there, but all over the world.

M: You lost me there. Volcanoes are hot. How can something hot prevent ice from melting?

W: Wait a minute, let me check my notes. Yeah, here it is. Volcanic heat melts just enough ice to create a slippery surface on the bottom of the glacier. This water allows ice to flow out into the ocean. So the solid interior ice is protected from the ocean's warmth. Does that make sense?

M: Son of. You mean that because the ice is flowing out to the ocean, the warmer ocean water can't flow in.

W: Exactly. And the ice that melts is constantly being replaced by snow. Prof. Smith said that if the ice sheet ever broke up and melted, the sea level would go up seven meters. Then we would have those floods.

M: Is that really possible? Or is it one of those exaggerations you hear all the time?

W: As far as I can understand, it is possible, because of global warming. I mean if the ocean got a lot warmer that interior ice would be very likely to melt.

M: Thanks for telling me about the lecture. Sounds like I've missed a pretty important class.

Why did the man ask about the lecture?

A．He wasn't present at the lecture.

B．He didn't listen to the lecture attentively.

C．He didn't appreciate the lecture.

D．He disliked some part of the lecture.

Firefighters are often asked to speak to school and community groups about the importance of fire safety, particularly fire prevention and detection. Because smoke detectors reduce the risk of dying in a fire by half, firefighters often provide audiences with information on how to install these protective devices in their homes.

Specifically, they tell them these things: A smoke detector should be placed on each floor of a home. While sleeping, people are in particular danger of an emergent fire, and there must be a detector outside each sleeping area. A good site for a detector would be a hallway that runs between living spaces and bedrooms.

Because of the dead-air space that might be missed by hot air bouncing around above a fire, smoke detectors should be installed either on the ceiling at least four inches from the nearest wall, or high on a wall at least four, but no further than twelve, inches from the ceiling.

Detectors should not be mounted near windows, entrances, or other places where drafts (过堂风) might direct the smoke away from the unit. Nor should they be placed in kitchens and garages, where cooking and gas fumes are likely to cause false alarms.

One responsibility of a firefighter is to ______________.

A.install smoke detectors in residents&39; homes

B.check if smoke detectors are properly installed

C.develop fire safety programs for schools

D.speak to residents about how to prevent fires
