答案：it is the most relevant to their field trip
原文定位：So let's include the mountain one. That's what they need to know about for geology. Then there are similar guidelines for caving, but they won't need those in the part of Iceland we're going to
同义替换：「most relevant to their field trip」↔「what they need to know about for geology」
答案：they get too absorbed in their tasks
原文定位：But what about not scaring birds or damaging rare plant life? Actually, what I think happens is that they all become so focused on what they're doing that they forget about other things around them. It's not intentional damage
同义替换：「harm the environment」↔「damaging rare plant life」，「get too absorbed in their tasks」↔「become so focused on what they're doing」
答案：keep collecting to a minimum
原文定位：For example, only take minute samples and only if necessary. Yes, that's the golden rule. That has to come first
答案：taking them from man-made structures
原文定位：And there's something we still have to find out about. Isn't there something about how you can never take a sample from a wall? You mean a man-made wall or something like a natural rock face? A wall, like of a building. Don't you just have to get permission from the owner? But I'm not sure, to be honest, so we need to check that
同义替换：「still have to find out about sampling」↔「need to check the rule of sampling from walls」，「man-made structures」↔「building walls」

原文定位：But when people are working on the seashore, they often fail to notice that the tides come in, and they're cut off by water. That's what we should make a point about
答案：energy for agriculture
原文定位：No, it deals with harnessing the heat generated from the earth in geothermal areas to grow vegetables for local consumption
答案：unique geological features of Iceland
原文定位：The reading pack called The Hot Spot will help them understand how Iceland differs from other islands formed at the same time, like Bermuda and the Canary Islands. It's the existence of the hot spot that explains the rock formations of this island and makes it unlike any of the others
答案：risk of flooding
原文定位：they need to be aware that although the ice and glaciers up in the mountains can stay frozen for thousands of years, if anything happens to make the glaciers melt suddenly, the water produced pours down the valleys, and it can mean that whole villages suddenly have to be evacuated
答案：long-team effects of volcanoes
原文定位：Then the Basalt Rock pack shows how Iceland's landscape, like many other islands, has been molded over millions of years by lava flows from volcanic eruptions, especially the area in the northwest of the island
答案：replacement of fossil fuels
原文定位：And lastly, reading about geothermal power plants will inform them of Iceland's plan to stop using energy derived from carbon in the future. Heating and electricity will come from sustainable sources which won't cause any pollution
