Kenya is the first country to try and protect elephants by text message. Mobile phone SIM cards inserted in the collars(项圈) of elephants automatically send a text message when they get too close to farms, allowing wildlife workers to drive them off rather than shoot them.
Hungry elephants cause big problem for farmers and villagers in some parts of Kenya looking for food and destroying homes and livelihoods in the process. Two years ago the Kenyan wildlife service had to shoot five elephants with regret and sadness who continued to destroy crops.
In an attempt to avoid such destructive actions the Save the Elephants charity installed a mobile phone SIM card in a collar that was placed on a huge bull elephant called Kimani. The conservationists( 自然环境保护者) then set up a virtual fence using a global positioning system.
Each time Kimani came near the fence, a text message was sent to workers. So far he has been prevented from going into farms fifteen times.
The project is expensive requiring five full time staff and a vehicle but it seems to be working successfully as Kimani hasn't come near a farm for four months. A similar system has now been carried out in another part of the country.
One of the biggest benefits of the project is that elephants seem to learn from one another.
Tracking and controlling one elephant can help a whole group change their habits.
The elephants can also be tracked using Google Earth software. This is also helping to prevent illegal hunting and killing as the workers know where to concentrate their resources to best protect the animals.
45. Which of the following is NOT a benefit of the project?
A. To extend elephants' habitat.
B. To protect farms from being destroyed.
C. To make more elephants change their habits.
D. To prevent elephants from being shot.
46. The fence mentioned in Paragraph 3 __________________________________ _.
A. can be seen by elephants B. actually refers to the text message
C. has prevented Kimani for 50 times D. doesn't exist in fact
47. According to the passage, the project ____________________.
A. costs just a little B. is carried out all by machine
C. seems to work out well D. is carried out across Kenya
45---47 ADC

举一反三期末百分冲刺卷系列答案If you give something to someone for free, will that person value it and use it? Development experts have debated this question for decades. Some think the act of paying causes people to value something and use it more.
Selling necessary health treatments, others argue, may deny them to the people who need them the most.
Consider, for example, chemically treated bed nets, which kill mosquitoes anti protect people against malaria(疟疾)while they are sleeping. William Easterly, an economist at New York University, believes this is one example of development having gone wrong. In a recent book, Professor Easterly suggests bed nets given free in Africa are often used for the wrong purpose. Yet, the World Health Organization (WHO) recommends bed nets be given out free and used by whole communities. The success of a large free bed net campaign in Kenya led the WHO to announce this recommendation
This debate will likely influence social programs in the developing world. Many non-governmental organizations support the creation of self-supporting programs in poor countries. Goods and services are sold for a price to help these programs survive.
According to Rachel Glenerster, who runs a research lab doing development and poverty studies at the Massachusetts Institute of Technology, her several studies have proven that small price changes have a big influence on the number of people who use a product. A price change will reduce the total amount of use of the product as well, she says. She has also found no evidence that the very act of paying for something changes how people use it.
As for a particular product among special populations, some development experts argue that pricing is useful. When it comes to bed nets, Miss Glenerster says research shows no evidence of this. People are just as likely to use a bed net whether they paid for it or not.

Kenya is losing an average of 100 of its 2,000 lions each year because of growing human settlements, increasing farming, climate change and diseases, according to the Kenya Wildlife Service (KWS).
“Lions have a special place in Kenyans’ life,” said Paul Udoto, a spokesman for the organization. “Other than being the symbol of national strength, they are among the Big Five, a main attraction for visitors to Kenya.”
There were 2,749 lions in Kenya in 2002 and their population dropped to 2,280 by 2004 and to about 2,000 today, according to KWS figures.
“The fall of the lion population is worrying and every effort needs to be made to make sure that Kenya either protects its population of 2,000 lions at present or increases the numbers to an ecologically (生态上地) acceptable level,” said Mr. Udoto.
“There is no doubt that the numbers are in free fall. I’d be surprised if they even last as long as 20 years,” said Laurence Frank, project director of Living With Lions, a Kenya-based animal protection organization. “When I first came here 30 years ago, I would always hear lions roaring across the land at night and see their tracks in the morning. Now that is very rare.”
“The reason is simple. As the numbers of people grow and the numbers of cows increase, they take up much of the lion’s space. Alongside that there are other ways, including poisoning, to kill lions.”
Animal lovers are making a new strategy to save the animals. Part of the measures will include tracking lions fitted with radio collars (无线电项圈) in the Amboseli area in southern Kenya, close to the border with Tanzania.
Wildlife officials in Tanzania face similar challenges in protecting their lions, but there is far less human encroachment（侵犯) on the animals’ homeland there than in Kenya.
