Free and secure accommodation, no bills and even the odd home-cooked meal. It sounds like the perfect living arrangement for cash-strapped(缺乏现金的) students.
Two mothers believe they have devised a way for struggling students to save on accommodation costs when they leave home to study at university.
Kate Barnham and Amanda Flude have launched Student Swaps, an online accommodation forum (论坛) for parents and students, in advance of the introduction in September of ￡3,000 higher education top-up fees.
Their website says, “The principle behind Student Swaps is to enable students to literally swap (交换) family homes.” The website will hold a database of students who would like to swap and link them with suitable matches. So those from one town / city could swap with those from a different town / city.
The site describes itself as offering a “cost-free accommodation alternative… at a time of growing student debt”. There is no charge for the service at the moment but Ms Barnham and Ms Flude intend to introduce a ￡10 annual fee if it becomes established.
However, the National Union of Students (NUS) has warned that, while the scheme may sound appealing to struggling freshers, it lacks any formal regulation.
Veronica King, NUS vice-president of welfare, said, “The fact that this scheme has even been suggested is evidence to the high levels of debt students now face on graduation.” Recent research has shown that students are more likely to live at home in coming years, in a bid to cut down on the cost of a degree.
“This is worrying, as it may mean that students choose their university on the basis of where it is, rather than because it offers the best course for them. It also means students will miss out on what is for some a key part of the student experience-living away from home.”

A Battery’s Nightmare
Portable electronics that can be carried about easily are only as good as their batteries (电池) and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go.
The engine---about the size of a ten-cent coin---starts with a combustion chamber (燃烧室) that burns hydrogen. Its tiny parts are etched (蚀刻) onto silicon wafers (硅片) in the same manner that computer parts are etched onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.
But the devil in all this nice detail is efficiency. Tiny engine parts don’t always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.
The scientists’ goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t likely until at least the end of the next ten years.

You may picture firefighters holding a hose (水管) outside of a burning building, but the Golden Eagles Hotshots don’t fight fires quite that way. When they go into action, you may not even see a fire truck.

The Hotshots are firefighters who battle fires in wildness areas. But don’t think you’ll only find them in their home state California. Wherever there is a national wildfire emergency, the Golden Eagles Hotshots could be there.

But these firefighters don’t work the same way as firefighters in a big city. They work in areas where there are a large number of trees, bushes, and grass. They climb up and down steep hills to clear brush and burnable debris（残骸）. They sometimes use water, but they often fight fire with fire!

They do that by lighting what are called “backfires,” which are small, controlled fires that burn up fuel in the path of large wildfires. That way, when the wildfire gets there, it has nothing to burn and nowhere to go, because all the burnable fuel has already gone up in smoke.

The Hotshots also clear away fuel using old-fashioned hard work. For example, they use a saw to cut away trees and heavy brush that could catch fire.

Of course there are times when the Golden Eagles Hotshots do have trucks to supply water to the fires. But the water is limited, and these guys have to rely on hard work more than anything. Physical fitness is very important. They have to be in great physical shape to handle steep hills and difficult terrain(地形) while carrying a 60-pound pack.

The Golden Eagles Hotshots definitely work hard for their pay. But thanks to their efforts, many lives have been saved, many houses have not burned, and countless trees are still standing.

1.67. The firefighters mentioned in the passenger. 

2.68. According to the passage, why do the firefighters light “backfires”?

3.69. What can we learn about the Golden Eagles Hotshots?

4.70. What is the author’s attitude towards the Golden Eagles Hotshots?
