One of the world's richest men has taken a close interest in one of man’s most basic functions: visiting the toilet．Bill Gates’s charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world．

So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount of potential drinking water．Secondly, they are more likely to cause pollution．This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations．Younger people are particularly at risk．Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year．Finally, standard lavatories simply aren’t practical in remote areas．

The challenge set by Bill Gates was to come up with a latrine which works without running water, electricity or aseptic tank(化粪池)．It also needed to operate for less than 5 cents．28 designs were displayed at the recent Reinvent the Toilet Fair in Seattle, USA．Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing．

But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology（CIT）picked up a prize of $ 100,000.

But clearly Bill Gates doesn’t feel he’s flushing money down the toilet．After the Seattle event he said, “We, couldn’t be happier with the response we’ve gotten,” Gates has even pledged $370m more to the future toilet project．They hope to field test more prototypes over the next three years．

1.Why is Bill Gates paying people to invent new toilets?

A．Because he wants to test people’s sense of creativity．

B．Because he wants to improve sanitation for many people．

C．Because he thinks the traditional ones are out of fashion．

Antarctica has become one of the world’s most popular tourist destinations. Since 1969, the average number of visitors to the continent has increased from several hundred to over 34,000 today. All activities in Antarctica are heavily supervised by the Antarctic treaty for environmental protection purposes and the industry is largely managed by the International Association of Antarctica Tour Operators (IAATO).

The first expedition (探险) to Antarctica with travelers was in 1966, led by Swedish explorer Lars Eric Lindblad. He wanted to give tourists first-hand experience of the ecological sensitivity of the Antarctic environment, in order to educate them and promote a greater understanding of the continent’s role in the world. In 1969, Lindblad built the world’s first expedition ship, the MS Lindblad Explorer, which was specifically designed to transport tourists to Antarctica.

In 1977, both Australia and New Zealand started to offer scenic flights to Antarctica through Qantas and Air New Zealand. The flights often flew to the continent without landing and returned to the departure airport. The experience was an average 12 to 14 hours with up to 4 hours of flying directly over the continent. The flights from Australia and New Zealand stopped in 1980. It was largely due to the Air New Zealand Flight 901 accident on November 28, 1979. In 1994, flights to Antarctica continued again.

Despite the potential dangers and risks, trips to Antarctica continued to grow. According to IAATO, 34,354 travelers visited the continent between 2012 and 2013. Americans contributed to the largest share with 10,677 visitors, or 31.1%, followed by Germans 11.1%, Australians 10.7%, and the British 10.2%. The rest of the visitors were from China, Canada, Switzerland, France and elsewhere.

The cost of a trip to Antarctica can range from as little as $3,000-$4,000 to over $40,000, depending on the scope of transportation, housing, and activity needs. The higher end packages typically involve air transport, on-site camping, and a visit to the South Pole.

1.Which can best replace the underlined word “supervised” in Paragraph 1?

A.Protected. B.Monitored.

C.Supported. D.Forbidden.

2.What’s Lars Eric Lindblad’s original purpose in getting to Antarctica?

A.To make himself the first explorer to go to Antarctica.

B.To transport more and more tourists to Antarctica.

C.To get first-hand experience of precious resources.

D.To let people know the significance of the continent.

3.What do we know about the flights to Antarctica?

A.They were once cancelled for more than ten years due to dangers.

B.Natural conditions of Antarctica are unable to support their landing.

C.It takes 14 hours to fly from New Zealand to Antarctica directly.

D.Air New Zealand has much success in developing Antarctic tourism.

4.What can be learned from the passage?

A.It is very convenient for Americans to travel to Antarctica.

B.The travelers usually have 4 hours’ sightseeing on the continent.

C.The number of people travelling to Antarctica is increasing.

D.New Zealand is the first country to offer scenic flights to Antarctica.

5.What’s the best title for the text?

A.The development of Antarctica B.Antarctica, a dream tourist attraction

C.The history of tourism in Antarctica D.IAATO, a great organization
