A romantic message-in-a-bottle discovered by a mother and daughter at a Scottish beach has sparked（触发） a mystery about whether it could have travelled 5,000 miles across the seas from China.

Nicola MacFarlane, 41, and daughter Lucy, four, from Portobello, near Edinburgh, were looking for driftwood（浮木） on Portobello Beach when they came across an old glass bottle containing a note inside written in Mandarin. Now the family are trying to work out if the letter has managed the extraordinary journey across the Philippine Sea, into the Indian Ocean and through both the South Atlantic and the North Atlantic Ocean’s before washing up on the shores of Great Britain.
　　 It was written on Chinese Valentine’s Day or Qixi Festival as it is more traditionally known, lunar July 7, 2012, so it sent off as recently as six days ago because it followed the modern calendar, which celebrated the occasion on August 23. Nicola was still excited to read about the Chinese love story after having it translated.

“I really do hope that it is from China but even it is from nearer to home, it’s still a lovely gesture and an inspiring find. It’s a love story regardless of where it came from. Nicola, who runs a beach art business in Portobello, added: “I’m always at the beach looking for bits of driftwood but I’ve never come across anything like this before. We knew it was Chinese, but we had no idea what it said.’

Unable to read the Mandarin text, Nicola turned to the internet and her Australian friend, Julie Gould, whose daughter attended a Chinese school in Sydney.

Several hours later Julie returned with the news that it was in fact a love letter.

The translated letter reads: “Da Hai(Ocean), I hope no-one will get this bottle, as we just wish you can hear our voice, and get your blessing. Today is the Chinese Valentine’s Day, we pray that our relationship will last forever and we will have a long happy life together…”

Nicola said: “It sounds to me like the couple are in love but cannot be together so they have sent the message to tell the world of their love.”

1.When did Nicola and her daughter come across the message-in-bottle?

A. On July 15, 2012.　　　　 B. On August 29, 2012.

C. On August 31, 2012.　 　　 D. On September 2, 2012.

2.What were Nicola and her daughter probably doing when they found the bottle?

A. They were walking on the beach.

B. They were washing hands and feet.

C. They were looking for the driftwoods.

D. They were lying on the beach resting.

3.The underlined word “Mandarin” probably means “　　　　　 ” .

A. Scottish　 B. British

C. English　　 D. Chinese

4.We can learn from the passage that Nicola__________.

A. thinks the letter was written to show love

B. had expected to get something unusual

C. knows a little Chinese

D. found the bottle was from a nearby place

The spectacular Victoria Falls links two countries, Zimbabwe and Zambia．It was discovered by David Livingstone in November 1855 and is known in the local language, as Mosi-oa-tunya, “the smoke that thunders”．It was Livingstone who named Victoria Falls after his Queen and stated in his own famous diary entry--- “Angels in their flight must have gazed．”

Adventure sports and a range of accommodation

The rustic（乡村的）Victoria Fall town--- just ten minutes from the Fall, and on the outskirts of the Zambezi National Park--- has all facilities necessary to act as a base for exploring the region．Accommodation is plentiful--- from low budget campsites to luxury hotels．

And across the border in Livingstone, Zambia, visitors will find a town suitable for the adventure sports enthusiasts with lots of travel and adventure sports companies．

Victoria Bridge--- the third highest Bungee jump in the world

At a height of 364 feet, the Victoria Falls Bridge, completed in 1905, is the world’s third highest Bungee jump, though the scream factor is arguably the loudest, making it a great draw-card for adventure sports enthusiasts．While dropping into the abyss (深渊), you will be blasted with spray from the thundering Victoria Falls, and then jerked (猛烈) back to reality within inches of the swirling eddies (漩涡) of the Zambezi below．

How to enjoy the Victoria Falls Experience--- take to the sky’s and the water

Anyone can pay an entrance fee and walk around the ridge of Victoria Falls and take some good pictures to send home, but to truly experience the size and scope of the spray, you’ve got to get airborne, and there are options--- tame and a little wild: fixed wing planes, helicopters, microlights．

River Rafting, in many shapes and sizes, is conducted on both sides of the Zambezi River, in Zimbabwe and Zambia below Victoria Falls．

63．What is the passage mainly about?

A．The introduction to the adventure sports at Victoria Falls．

B．The description of the beauty of Victoria Fall．

C．The development of the adventure sports in this region．

高三英语单项填空简单题查看答案及解析

Scientists have exactly discovered the set of brain cells involved in making risky decisions, and have been able to control them in rats using targeted light. By changing the activity of the cells they were able to change the behaviour of risk-taking rats to avoid risk, hinting the approach could in future be used to treat people with impulse (冲动) control problems.

Risk-taking is a key part of survival, knowing when to take a chance could pay off—such as moving to a new area to look for food when pickings are slim.

While all animals need an element of risk, the preference towards it varies between individuals. Researchers found this variation, which determines how risk-averse an individual is, is regulated by brain cells in a region of the brain called the nucleus accumbens. This cluster of neurons releases the neurotransmitter dopamine, which regulates the brain’s reward and pleasure centres.

Previous studies have shown that in patients with Parkinson’s disease, taking medication which blocks specific dopamine receptors (DR2) (受体) leads to increased gambling (赌博) behaviour and risk taking behaviour. In studies with rats, researchers were able to use a technique called optogenetics (光遗传学)—which uses light sensitive proteins to change the activity of cells—to modify cells with DR2 in the nucleus accumbens.

Rats were trained to choose one of two levers, offering them a choice between a “safe” or “risky” choice. The safe option resulted in a small, but consistent amount of a sugar water treat. But the risky choice consistently delivered smaller amounts of sugar water, with the occasional large pay off—essentially encouraging the animals to gamble for a bigger prize. Around two-thirds of the animals weren’t keen on risk, opting for the safe option, but the remaining third were risk-seekers. Brain scans of the animals showed that those with low levels of DR2 consistently went for the gamble.

But using pulses of light to stimulate (刺激) the DR2 cells and improve their activity could cause the risk-takers to play it safe and opt for the guaranteed but less rewarding option. Once the light-pulses stopped, the risk-takers returned to their gambling strategy.

In the risk-averse animals, stimulating the same cells had little to no effect.

Professor Karl Deisseroth, of Stanford University in California, said: “Humans and rats have similar brain structures involved.”And we found a drug known to increase risk preference in people had the same effect on the rats. So every indication is that these findings are relevant to humans. “Risky behavior has its moments where it’ s valuable. As a species, we wouldn’t have come as far as we have without it.”

1.The variation in people’s preference towards risks is directly regulated by ________.

A. nucleus accumbens　　　 B. light sensitive proteins

C. neurons　　　 　　　　　　 D. dopamine

2.From the experiment with rats, we can conclude that ________.

A. the lack of DR2 cells results in a safe option

B. the levels of DR2 have little to do with their choices

C. the high levels of DR2 can make animals avoid risks

D. the risky choice is a less rewarding option

3.The underlined words in Paragraph 7 most likely mean the animals that are ________.

A. willing to take big risks

B. reluctant to take risks

C. fond of gambling strategy

D. afraid of receiving stimulation

4.What can be inferred from what Professor Karl Deisseroth said?

A. Humans and rats differ in their preference for risk-taking.

B. Too much risk-taking can do more harm than good.

C. Risk-taking can be used to treat people with impulse control problems.

D. Risk-taking is a means of survival and brings higher returns to humans.
