Sunny countries are often poor. A shame, then...

Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around￡10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp (安培) current to store this electricity, and a lamp whose bulb is a light­emitting diode (二极管). The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile­phone charger for seven hours. Then, next day, it can be put outside and charged back up again.

The trick is that, to be able to use the electricity, the system’s keeper must buy a scratch card — for as little as a dollar — on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company’s server will respond automatically with an access code to the unit.

Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around￡80 worth of scratch cards — which Eight19 expects would take the average family around 18 months — the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10­watt solar cell.

In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.

According to Eight19’s figures, this looks like a good deal for customers. The firm believes the average energy­starved Kenyan spends around￡10 a month on oil — enough to fuel a couple of smoky lamps — plus￡2 on charging his mobile phone in the market­place. Regular users of one of Eight19’s basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.

1.The underlined word “get round” in the first paragraph can be replaced by “______”.

A.make use of B.come up with

C.look into D.deal with

2.What should the user do when the electricity in the battery is used up?

A.Buy a scratch card.

B.Recharge it outside.

C.Buy another solar cell.

D.Return it to the company.

3.How much would users pay for the cell and scratch cards before they own a 2.5­watt solar cell?

A.Around￡10. B.Around￡80.

C.Around￡90. D.Around￡180.

4.It can be inferred from the last paragraph that　　　　 .

A.Kenyan families would find it difficult to afford the solar cell

B.using the solar cell would help Kenyan families save money

C.few Kenyan families use mobile phones for lack of electricity

D.the company will make a great profit from selling solar cells

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it’s far from enough. Ladies and gentlemen, we’ve got to come up with some better ideas to help them.

I was very surprised, then, when I read about a plan to make cheap laptop computers（便携式电脑）for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia.

The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it will be covered in rubber so that it is very strong and won’t be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle（把手）so that children can wind（摇）the computer up to give it extra power when needed.

These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children’s education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children’s education they should help people to find their own solutions to their problems in the long term.

Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals（目标）at the same time. We will reduce the waste we produce and help others. In other words, we will be able to “kill two birds with one stone”, and that is always a good thing.
